Opis:

In this paper, we describe how several soft computing tools can be used to assist in high throughput screening of potential drug candidates. Individual small molecules (ligands) are assessed for their potential to bind to specific proteins (receptors). Committees of multilayer networks are used to classify protein-ligand complexes as good binders or bad binders, based on selected chemical descriptors. The novel aspects of this paper include the use of statistical analyses on the weights of single layer networks to select the appropriate descriptors, the use of Monte Carlo cross-validation to provide confidence measures of network performance (and also to identify problems in the data), the addition of new chemical descriptors to improve network accuracy, and the use of Self Organizing Maps to analyze the performance of the trained network and identify anomalies. We demonstrate the procedures on a large practical data set, and use them to discover a promising characteristic of the data. We also perform virtual screenings with the trained networks on a number of benchmark sets and analyze the results.

Opis:

This paper discusses various aspects that should be considered when defining and executing extraction process-related information from the source data (ERP system) to an event log. This includes trace and event selection, as well as important project decisions that should be made beforehand. The basic idea of a proposed approach is demonstrated by performing a case study which is related to a standard sales order processing, that is, business process from sales quotation through sales order and delivery to invoicing. For this processes we showed the characteristics of the event logs, and the models we can discover.

Opis:

The paper shows how a certain kind of underlying representations (or deep forms) of words can be constructed in a straightforward manner through aligning the surface forms of the morphs of the word forms. The inventory of morphophonemes follows directly from this alignment. Furthermore, the two-level rules which govern the different realisations of such morphophonemes follow fairly directly from the previous steps. The alignment and rules are based upon an approximate general metric among phonemes, e.g., articulatory features, that determines which alternations are likely or possible. This enables us to summarise contexts for the different realisations.

Opis:

The widespread particularist account of the onset of molecular biology that identifies it with the discovery of the DNA structure in 1953 has been recently contested. The paper contributes to this debate by focusing on a more recent discovery of small noncoding RNAs (microRNAs). First, it outlines a particularist account of the microRNAs discovery and the origins of the particularist predilection of the modern scientometric studies of science dynamics. Next, it discusses its limitations and proposes an alternative, modified processualist account of the discovery. In the final part, the paper applies this approach to unravel network dynamics of the research on the first two microRNAs that were discovered, namely lin-4 and let-7.

Opis:

The field of health care is an important element of the economic and social life of every country in the world combining demographic, economic and epidemiological, ethical and social challenges. Spending on the development of new therapies has been increasing over the past two decades, and the amount of drugs approved by regulatory agencies has remained stable. Literature does not provide adequate knowledge about the reasons of the productivity drop that impacts the competitive advantage of the companies taking part in the project’s race to the market (Schuhmacher et al., 2022), and it therefore seems crucial to analyse the factors determining high productivity of the pharmaceutical industry to adjust further actions ensuring the highest quality of health care systems, focusing on the wellbeing of the patient and the development of increasingly safer medicines. To address this need the author performed systematic literature review followed by structured interviews with 14 experts working globally in the field of drug development to determine productivity factors in drug discovery research and development projects, with the goal of answering questions related to which factors play a key role in the productivity of scientific organisations and the relationship between the factors, providing an insight into which parts of drug discovery ecosystem can increase a chance to address highly unmet medical needs of patients waiting for novel, safe and effective forms of treatment. As a result of the research 22 key productivity factors were defined and clustered into 4 categories: scientific, managerial, business, environmental and relations between the factors were discussed.

Artykuł jest oparty na korespondencji między Udo Wid’em i Karin Hofer a Łukaszem Guzkiem i Anką Lesniak. Dotyczy przygotowań do spotkania i konferencji w Dreźnie (Ostrale). Jest to przykład wymiany poglądów i tworzenia teorii w zamkniętej grupie (echo chamber). Jest także przykładem tego, jak w praktyce przebiega produkcja wiedzy w naukach humanistycznych oraz jaka rolę mogą odegrać badania artystyczne. Tak więc nowa dyscyplina Art(istic) research wykorzystuje metody artystyczne do tworzenia wiedzy o świecie, podczas gdy przyszłe ArtStudies prawdopodobnie będą wykorzystywać metody epistemiczne do tworzenia wiedzy o sztuce. Oba mogą się uzupełniać.
The article is based on the correspondence between Udo Wid and Karin Hofer and Łukasz Guzek and Anka Lesniak. Concerns preparations for meetings and conferences in Dresden (Ostrale). This is an example of exchanging views and creating theories in a closed group (echo chamber). It is also an example of how the production of knowledge in the humanities works in practice and what role artistic research can play. So the new discipline of Art (istic) Research uses artistic methods to produce knowledge about the world, while future ArtStudies will probably use epistemic methods to produce knowledge about art. Both perhaps will complement each other.

Opis:

Luck is one of the critical factors determining outcome of many activities we are involved in. In chemistry, and specifically in drug discovery a strike of luck can determine a successful study outcome leading to an approval of potentially blockbuster drug consequently offering a new treatment option for patients in need. On the other hand, lack of luck can often result in termination of activities, wasted resources and years of studies and often have negative impact on a fate of companies and its employees. In a similar fashion, hard work is critical for one’s success. It is not meant in a literal fashion, but rather from the perspective of “going the extra mile” in scientific research and development. It is meant as a proper approach to analysis of study outcome and understanding the reasons “why”, rather than accepting simply yes/no outcomes. Below article discusses two instances where certain level of luck and extra effort invested in understanding of widely available results led to development of two novel therapeutics in oncology field. Described stories deal with development of Abraxane, novel formulation of paclitaxel commercialized by Abraxis Bioscience as well as enzalutamid (Xtandi®) discovered at UCLA and developed and commercialized by Medivation and Astellas Pharma.

We demonstrate the implementation of the proposed method on two real world healthcare datasets. Formal Concept Analysis (FCA) is a mathematical framework that offers a conceptual knowledge representation through hierarchical conceptual structures called concept lattices. However, during the design of a concept lattice, complexity plays a major role.

Opis:

Purpose: the main purpose of this paper is to define the scope in which the entrepreneurial discovery process for smart specialization affects the technological development of the region. Design/methodology/approach: Based on theoretical analysis of the concept of smart specialization and entrepreneurial discovery process (EDP), set of research tools and methods has been proposed, including broad participation and interaction between EDP participants. The research tool – questionnaire for studying the needs of entrepreneurs in the direction of technological development of the Silesian Voivodeship consisted of four thematic blocks, including such aspects, as: innovative activity, financial aspects and the effectiveness of obtaining funds, cooperation and development strategy. A representative group of 300 companies was selected to participate in the survey. The responses obtained were processed and generalized using statistical methods – with use of MS Excel and Statistica software. The results of the research, conducted in 2017-2019, were used as a tool to identify areas of technological and cooperation advantage in the Silesian Voivodeship and recommendations for the update of Regional Technological Program for the 2030 perspective. Findings: The role of different groups of actors is varies substantially in terms of their involvement and impact, with the stakeholders from business and research are the main group to be targeted in the entrepreneurial discovery process. Research limitations/implications: The results provide a basis to improve the effectiveness of regional development planning, especially solutions for SME involvement and cooperation. The results confirm, that a detailed study of entrepreneurs' needs should be included as the main instrument for the implementation and for gaining reliable information on the effectiveness of implemented solutions in the field of innovation support. Limitations of the study include the subjectivity of respondents' opinions and the relatively small research sample, which may limit the generalization of the results. Practical implications: The results of the survey indicate the existence in Silesian region of the distance between entrepreneurs and scientists (thinkers and doers), which may result in lessening of effectiveness and willingness of cooperation, without preventive measures on a regional scale. The results also confirmed, the existence of financial barriers for innovativeness activities, especially impeded access to external capital, translating into lost benefits. Originality/value: The contribution of the research to the development of innovation management process in the region, which is based on a broad process of collaboration with different stakeholder groups. The results provide a contribution to the operationalization of the entrepreneurial discovery process.

W referacie zaprezentowano problem zastosowania nowej dziedziny inżynierii wiedzy, jaką jest odkrywanie wiedzy w bazach danych w zakresie identyfikacji ilościowych modeli diagnostycznych. Przedstawiono genezę tej dziedziny, scharakteryzowano ją jako interaktywny i iteracyjny proces, a także wymieniono zadania oraz metody, jakimi się ta dziedzina posługuje. Szczególną uwagę zwrócono na metody odkrywania zależności funkcyjnych. W dalszej części referatu przedstawiono przykładowe zastosowania do zadań odkrywania statycznych zależności przyczynowo-skutkowych i "diagnostycznych" oraz zależności dynamicznych. W podsumowaniu dokonano analizy uzyskanych wyników oraz przeprowadzono dyskusję dotyczącą wprowadzenia zmian poz.walających zastosować te metody w praktyce.
The paper deals with the problem of application of the new knowledge engineering domain, which is the knowledge discovery in databases (KDD), for the identification of quantity diagnostics models. The origin of the domain was presented. Then KDD was characterized as an interactive an iterative process. The tasks and methods used were specified, as well. The special attention was paid to the methods of discovering functional dependencies. The exemplary applications to tasks of static cause-and-effects and "diagnostics" dependencies and also dynamics dependencies were presented in the further past of the paper. The analysis of the obtained results was included in the summary, which discusses some changes in the KDD methodology allowing to put these methods into practice.

One of the benefits of such technological convergence is that grid resources and applications can be virtualized by services and offered through the SOA paradigm. In the broad and interoperable scenarios enabled by the SOA, involving the participation of several grid infrastructures across many administrative domains, service discovery can be a serious issue. In this paper we present a P2P-based infrastructure that leverages semantic technologies to support a scalable and accurate service discovery process. The key concept of the presented idea is the creation of an overlay network organized in several semantic groups of peers, each specialized in answering queries pertaining to specific applicative domains. Groups are formed by clustering together peers offering services that are semantically related. The architecture details of the proposed solution are presented. A system prototype has also been implemented and validated through a case study deployed on the PlanetLab testbed.

Opis:

The Google Shopping case has provided significant lessons that reach beyond antitrust enforcement. ‘Enabling and discovery tools’ create a layer that serves as a gateway to the Internet ecosystem. Therefore, on the one hand, they play a key role in ensuring the openness of the Internet ecosystem, and on the other hand, they exercise a primary influence on consumer experiences and their cognitive processes, which in turn determine online consumer transactions. Enabling and discovery tools, such as adopting design methods based on applied behavioural sciences (for example: user experience design (UX) and user interface design (UI)), create global challenges at the crossroads of antitrust, consumer law and platform regulation. At the same time, in light of the complexity of the platform economy, some market phenomena might be particularly difficult to identify and address, while fast and efficient adaptation is an essential factor for market players. This brings advocacy – the promotion of a competitive environment – into the focus also at the national level, particularly where a dual enforcement regime makes a multifocal approach possible.
L’affaire Google Shopping a fourni des leçons importantes qui vont au-delà de l’application du droit de la concurrence. Les «outils d’activation et de découverte» créent une couche qui sert de passerelle vers l’écosystème d’Internet. Par conséquent, d’une part, ils jouent un rôle clé pour assurer l’ouverture de l’écosystème d’Internet et, d’autre part, ils exercent une influence primordiale sur les expériences des consommateurs et leurs processus cognitifs, qui à leur tour déterminent les transactions des consommateurs en ligne. Les outils d’activation et de découverte, tells que l’adoption de méthodes de conception basées sur les sciences comportementales appliquées (par exemple: la conception de l’expérience utilisateur (EU) et la conception de l’interface utilisateur (UI)), créent des défis mondiaux au carrefour du droit de la concurrence, du droit de la consommation et de la réglementation des plateformes. Dans le même temps, compte tenu de la complexité de l’économie des plateformes, certains phénomènes de marché pourraient être particulièrement difficiles à identifier et à traiter, alors qu’une adaptation rapide et efficace est un facteur essentiel pour les acteurs du marché. Cela place le plaidoyer pour la promotion d’un environnement concurrentiel au centre de l’attention également au niveau national, en particulier là où un double régime d’application du droit rend possible une approche multifocale.

Opis:

Zwolennicy tradycyjnej filozofii nauki opowiadali się za wprowadzeniem rozróżnienia na kontekst odkrycia i kontekst uzasadniania, czyniąc ten ostatni jedynym właściwym przedmiotem filozoficznej refleksji. Wielu badaczy nie zgadzało się z tym rozstrzygnięciem. Niektórzy z nich podjęli wysiłki opracowania normatywnej teorii odkrycia naukowego. Dzięki zastosowaniu zaawansowanych maszyn liczących starano się stworzyć program komputerowy generujący odkrycia naukowe. Doprowadziło to do powstania odrębnej dziedziny nauki – teorii odkryć maszynowych – czerpiącej z dorobku psychologii rozwiązywania problemów i badań nad sztuczną inteligencją. Celem pracy jest dowiedzenie, że żadna z prób oparcia odkrycia naukowego o procedury stosowane przez komputery jest nierealizowalna z przyczyn logicznych. W poniższej pracy przedstawiono historyczny proces, który doprowadził do wyodrębnienia się kontekstów odkrycia i uzasadnienia oraz wskazano badaczy i nurty, które sprzeciwiły się podziałowi na kontekst odkrycia i kontekst uzasadnienia. Następnie nakreślona została teoria odkryć maszynowych, której autorzy podjęli się próby skonstruowania programu komputerowego generującego odkrycia naukowe. Artykuł wieńczy przybliżenie racji logicznych, które czyniły ich starania niemożliwymi do zrealizowania. W toku badań wykazano, że istnieją przekonujące racje logiczne, by uznać, że algorytmizacja odkrycia naukowego nie jest programem badawczym, którego cele mogły być osiągnięte. Przybliżono szereg racji odwołujących się do natury poznania komputerowego, które czynią nadzieje badaczy na sukces programu płonnymi. Poznanie komputerowe ma charakter dedukcyjny, jest treściowo puste, ponieważ nie może dostarczyć żadnej nowej wiedzy. Chociaż wykorzystanie komputerów w pracy badawczej wydaje się decyzją słuszną, albowiem poprzez możliwości analizy ogromnej liczby danych otwierają przed naukowcami zupełnie nowe możliwości, maszyny liczące nie zastąpią naukowców całkowicie. Niezależnie od postępu technologicznego natura poznania komputerowego sprawia, że odkrycie naukowe będzie wymagało ludzkiej interwencji, a wszelkie próby redukcji odkrycia do czynności właściwych komputerom są skazane na niepowodzenie.
Adherents of traditional philosophy of science supported the distinction between context of discovery and context of justification, making the latter the only actual subject of philosophical inquiry. Many scientists did not follow this conclusion. Some of them tried to construct normative theory of scientific discovery. Due to application of advanced computing machines, they endeavoured constructing a computer programme as it would be able to generate scientific discoveries. It led to the emergence of separate scientific discipline – a theory of machine discovery that was based on the work of psychology of problem solving as well as artificial intelligence. The goal of the paper is to present argumentation in favour of the view that none of the attempts of reducing scientific inquiry to computation can succeed due to logical purposes. The paper shows the historical process that led to the distinction of context of discovery and context of justification as well as indicates the scientists and trends that objected such a distinction. Subsequently, the paper presents the theory of machine discovery, which authors tried to construct a computer program that would generate scientific discoveries. Last part of the material is dedicated to logical arguments that make such attempts unable to succeed. The inquiry showed that there are logical arguments to state that the algorythmization of scientific discovery is not possible. The paper delivers argumentation, derived from the nature of machine cognition that makes such attempts impossible to succeed. Machine cognition is deductive, without reference to any subject, has no content and can be reduced to the data given to the input of the system. While using the computers in scientific inquiry seems to be a reasonable decision, because of the possibility of analysing great sets of data what opens new possibilities to scientists, the computers will never be a substitute for human beings. Regardless of the technical development, the nature of machine cognition makes scientific discovery dependent on human intervention. All attempts of reducing discovery to computing procedure cannot, necessarily, succeed.

Opis:

The simulation and modelling paradigms have significantly shifted in recent years under the influence of the Industry 4.0 concept. There is a requirement for a much higher level of detail and a lower level of abstraction within the simulation of a modelled system that continuously develops. Consequently, higher demands are placed on the construction of automated process models. Such a possibility is provided by automated process discovery techniques. Thus, the paper aims to investigate the performance of automated process discovery techniques within the controlled environment. The presented paper aims to benchmark the automated discovery techniques regarding realistic simulation models within the controlled environment and, more specifically, the logistics process of a manufacturing company. The study is based on a hybrid simulation of logistics in a manufacturing company that implemented the AnyLogic framework. The hybrid simulation is modelled using the BPMN notation using BIMP, the business process modelling software, to acquire data in the form of event logs. Next, five chosen automated process discovery techniques are applied to the event logs, and the results are evaluated. Based on the evaluation of benchmark results received using the chosen discovery algorithms, it is evident that the discovery algorithms have a better overall performance using more extensive event logs both in terms of fitness and precision. Nevertheless, the discovery techniques perform better in the case of smaller data sets, with less complex process models. Typically, automated discovery techniques have to address scalability issues due to the high amount of data present in the logs. However, as demonstrated, the process discovery techniques can also encounter issues of opposite nature. While discovery techniques typically have to address scalability issues due to large datasets, in the case of companies with long delivery cycles, long processing times and parallel production, which is common for the industrial sector, they have to address issues with incompleteness and lack of information in datasets. The management of business companies is becoming essential for companies to stay competitive through efficiency. The issues encountered within the simulation model will be amplified through both vertical and horizontal integration of the supply chain within the Industry 4.0. The impact of vertical integration in the BPMN model and the chosen case identifier is demonstrated. Without the assumption of smart manufacturing, it would be impossible to use a single case identifier throughout the entire simulation. The entire process would have to be divided into several subprocesses.

Opis:

The paper introduces a Universal Plug and Play based discovery and management toolkit that facilitates collaboration between cloud infrastructure providers and users. The presented tools construct a unified hierarchy of devices and their management-related services, that represents the current deployment of users' (virtual) infrastructures in the provider's (physical) infrastructure as well as the management interfaces of respective devices. The hierarchy can be used to enhance the capabilities ofthe provider's infrastructure management system. To maintain user independence, the set of management operations exposed by a particular device is always defined by the device owner (either the provider or user).
Artykuł opisuje zestaw narzędzi opartych na technologii Universal Plug and Play, wspomagających współpracę pomiędzy użytkownikami i dostawcą usług w zakresie wykrywania zarządców wirtualizacji (ang. hypervisor) i maszyn wirtualnych oraz zarządzania nimi. Prezentowane narzędzia konstruują spójną, hierarchiczną reprezentację rozmieszczenia maszyn wirtualnych w infrastrukturze fizycznej, zawierającą opisy fizycznych i wirtualnych urządzeń oraz usług służących do zarządzania nimi. Struktura ta może być wykorzystana przez dostawcę usług np. w celu optymalizacji wykorzystania posiadanych mocy obliczeniowych. W celu zachowania niezależności pomiędzy użytkownikami i dostawcami infrastruktury przyjęto założenie, że zbiór usług oferowanych przez poszczególne urządzenia jest określany przez jego posiadacza.

Rozwój technologii automatycznego gromadzenia i przechowywania informacji jest wynikiem nagłego wzrostu rozmiarów przechowywanych danych i eksplozją danych. Nowe możliwości daje ciągły wzrost mocy obliczeniowej i pojemności pamięci, jednak posiadanie danych nie jest równoznaczne z posiadaniem wiedzy zawartej w tych danych. Dla podejmowania lepszych decyzji i wyciągnięcia wniosków konieczna staje się zaawansowana analiza dużych wolumenów danych. Techniki eksploracji danych pozwalają na znajdowanie nieznanych zależności pomiędzy danymi, co przyczynia się do wspomagania podejmowania decyzji. Celem artykułu jest prezentacja rozwiązań związanych z odkrywaniem wiedzy w bazach danych, poprzez omówienie technik eksploracji danych oraz reprezentacji odkrywanej wiedzy z jej praktycznym zastosowaniem.
Development of technologies for automated collection and storage of information is a result of a sudden increase in the size and amount of storage data. Continuous increase of computing power and storage capacity gives new opportunities, but having the data is not synonymous with having the knowledge contained in these data. For making better decisions and drawing conclusions, it is necessary to make an advanced analysis of large volumes of storage information. Data mining techniques (called. Data Mining) allow you to find the unknown relationship between the data, which helps to support decision-making.

Opis:

Recently, business protocol discovery has taken more attention in the field of web services. This activity permits a better description of the web service by giving information about its dynamics. The latter is not supported by theWSDL language which concerns only the static part. The problem is that the only information available to construct the dynamic part is the set of log files saving the runtime interaction of the web service with its clients. In this paper, a new approach based on the Discrete Wavelet Transformation (DWT) is proposed to discover the business protocol of web services. The DWT allows reducing the problem space while preserving essential information. It also overcomes the problem of noise in the log files. The proposed approach has been validated using artificially-generated log files.

Opis:

The paper is of a review character and in historical terms, it contains an overview of research on polonium from the time of its discovery in 1898 (125 years ago) to the present time. The article contains a description of the state of knowledge about the chemistry of polonium, taking into account its physicochemical properties, as well as methods of its production and the radioactivity of its isotopes, as well as its current scientific and industrial applications. The issue of strong radiotoxicity of polonium and the dangers associated with research on it, as well as numerous example of diseases and death from its absorption into the human body, are described in detail. Despite the passage of 125 years since the discovery of polonium, it still fascinates researchers with its mysteries that have not been fully understood, revealed and explained. The sources of this peculiarity should be sought in the fact that although it is classified as a metal, it also has non-metallic properties and can form a number of different chemical compounds. Several chemical compounds of polonium have been tested, which are very easy to get into the human body, where it causes terrible havoc. Alpha particles emitted from decay of 210Po can cause damage to proteins and DNA that load to cell death or such changes in the body that consequently initiate the development of cancer. So you could say that polonium not only has a rich past, but also has an undeniably interesting future.

Opis:

Internet protocol based networking is gaining ground in armed forces, leading to a concept described by the NATO as network centric capabilities (NCC). The goal is to enable state-of-the-art, affordable and powerful electronic information services to the troops. A tighter connection of the forces is expected to further enhance the joined strike capabilities. Providing secure information exchange within groups of armed forces is one aspect of the NCC concept. Such group communication is enabled by the multicast feature of the IP technology. Security requirements are met by using the IP security (IPsec) architecture. IPsec enables secure communication between secure private networks via an unsecured public text network. While secure unicast transmission with IPsec is common, only few achievements have been made to secure multicast transmissions. The protection of multicast data traffic of a group in an automated way is described in this document. We utilize an automatic detection of IPsec devices and an efficient key management protocol to reach our aim.

Opis:

A great breakthrough in development of biological sciences was the cell theory formulated in the first half of the 19th century. It permitted a reduction of the studies of a huge diversity of living organisms to analysis of a single animal or plant cell. Till the end of the 19th century the nervous tissue was not described in terms of this theory, because a simple optical microscope was an insufficient instrument when applied in the studies of such complex but fascinating structure. The implementation of the new method of staining proposed by Golgi - reazione nera, opened the possibility of structural investigation of the nervous tissue. Camillo Golgi and Santiago Ramon y Cajal were the first to apply this method in cytological studies. They worked separately, on the same set of data, but the interpretations presented by each of them led to substantially different conclusions. The work of Cajal has become fundamental for development of the neuron theory, which - together with the postulate of the functional localization - is basic for the current knowledge of the structure and function of the nervous system. Therefore, Santiago Ramon y Cajal has been recognized as the precursor of the research discipline known as neuroscience.

Machine discovery is a new area of artificial intelligence, dealing with computer systems which make discoveries. An automated discovery system can be imagined similarly to a human discoverer or to the sommunity of scientists-discoverers, as a robot that makes experiments and uses empirical data to develop theories. The author argues that construction of discovery system and theories of their functioning is a new and attractive program for the philosophy of science. He reviews the existing discovery systems and presents the theoretical schema emerging from their analysis. A large reference list provides directions for further studies.

Opis:

The historical past of a building has a key influence on the variability of geotechnical conditions. These conditions change with a modification of the structural system, a change in function or only architectural elements (fashionable in a given period). In the article, various geotechnical and geophysical surveys are described, which led to a discovery of potential causes of a structural failure at historical Castle of Dukes of Pomerania in Szczecin. The investigation resulted in a discovery of an underground tunnel system constructed under the Castle, which existence was only suspected. The tunnels were constructed primarily during II World War, but also before that period. The article summarizes facts discovered due to investigation as well as historical and geological background related to the execution of the reinforced concrete and masonry tunnels. The lesson learned resulting from this discovery is that great care should be taken when historical areas are considered, even if the structure seems to be massive and robust.
Historyczna przeszłość budynku ma kluczowy wpływ na zmienność warunków geotechnicznych. Warunki te zmieniają się wraz z modyfikacją układu konstrukcyjnego, zmianą funkcji lub tylko elementów architektonicznych (modnymi w danym okresie). W artykule opisano różne badania geotechniczne i geofizyczne, które doprowadziły do odkrycia potencjalnych przyczyn katastrofy historycznego skrzydła Zamku Książąt Pomorskich w Szczecinie. Przeprowadzone badania doprowadziły do odkrycia podziemnego systemu tuneli zbudowanych pod Zamkiem, których istnienie tylko podejrzewano. Tunele zostały zbudowane głównie w czasie II wojny światowej, ale także przed tym okresem. W artykule podsumowano aktualne fakty odkryte w wyniku badań oraz uwarunkowania historyczne i geotechniczne związane z wykonaniem tuneli żelbetowych i murowanych.

Opis:

In Ordovician erratic boulders land plants remains were found. They could be considered as more primitive than Psilophytales , and probably as the most primitive land plants. Two new genera : Musciphyton gen. nov. and Hepaticaephyton gen. nov. are distinguished.
W notatce tej autorzy informują o znalezieniu przez pierwszego z nich szczątków roślinnych wieku ordowickiego o charakterze roślin lądowych. Autor wypreparował te materiały z wapiennych narzutniaków ordowickich, zebranych w dolinie Wisły koło Zakroczymia, rozpuszczając je w kwasie solnym. Wapienie te, przywleczone ze Skandynawii przez lodowce czwartorzędowe, odpowiadają osadom morskim i zawierają szczątki zwierząt typowo morskich, jak graptolity, szkarłupnie, brachiopody, pierścienice (skolekodonty), hydroidy itp. Zawierają one tez grzyby niższe i algi ,zapewne również morskie. Wśród tych organizmów znalazły się jednak pewne rośliny o wyższej organizacji, które, według drugiego autora, są niewątpliwie lądowe. Rośliny te musiały być przyniesione do zbiornika morskiego z wybrzeży lądu. Odznaczają się one wyjątkowo doskonałym stanem zachowania. Szczegółowym ich badaniem zajął się drugi z autorów i wyniki je go pracy ogłoszone zastana w niedalekiej przyszłości. W niniejszej notatce wstępnej autor ten komunikuje, iż badane przez niego rośliny reprezentują dwa nowe rodzaje, którym nadaje nazwy Musciphyton i Hepaticaephyton, a grupę, do której będzie można je zaliczyć, nazywa prowizorycznie "Propsilophyta " . Są to rośliny pod wieloma względami prymitywniejsze, niż znane dotychczas z syluru i dewonu Psilophyta. Przypuszczalnie niewiele oddalają się one od teoretycznego prototypu roślin lądowych. Na razie autor ogranicza się do podania ogólnej tylko charakterystyki dwóch wyróżnionych przezeń rodzajów, ilustrując je zdjęciami fotograficznymi i rysunkami. Czyni równocześnie rozważania na temat znaczenia tego znaleziska dla zagadnienia pochodzenia i ewolucji roślin lądowych.

Opis:

The main purpose of a topological index is to encode a chemical structure by a number. A topological index is a graph invariant, which decribes the topology of the graph and remains constant under a graph automorphism. Topological indices play a wide role in the study of QSAR (quantitative structure-activity relationship) and QSPR (quantitative structure-property relationship). Topological indices are implemented to judge the bioactivity of chemical compounds. In this article, we compute the ABC (atom-bond connectivity); ABC4 (fourth version of ABC), GA(geometric arithmetic) and GA5(fifth version of GA) indices of some networks sheet. These networks include: octonano window sheet; equilateral triangular tetra sheet; rectangular sheet; and rectangular tetra sheet networks.

Opis:

Moldavites represent tektites derived from the Ries impact structure ca. 14 Ma. in southern Germany. Approximately 36 moldavite specimens from Poland have been reported since 2012. Characteristic moldavites features, especially bubbles and inclusions of lechatelierite, are reported in all found moldavites. Almost all of them are genetically connected with the Miocene Gozdnica Formation. Only two have been found in Pleistocene sediments, which are part of the Nysa Łużyca river terrace sediments. In 2020, four more moldavites have been collected from Poland. One specimen was found in Gozdnica village, and the other three in Jaroszów village, which is located ~10 km east of Strzegom. Numerous moldavites are generally found in Poland, widely distributed based on the distance from the Ries crater, exceeding 500 km, experimentally determined based on the transport mechanism. However, the lack of the autochthonous tektites indicates that tektites investigated up to now, had to be redeposited in a fluvial environment, probably from the Lusatian area as well as from the Czech Republic.

Opis:

We investigate structure of the Primary Language of the human brain as introduced by J. von Neumann in 1957. Two components have been investigated, the algorithm optimizing warfighting, Linguistic Geometry (LG), and the algorithm for inventing new algorithms, the Algorithm of Discovery. The latter is based on multiple thought experiments, which manifest themselves via mental visual streams (“mental movies”). There are Observation, Construction and Validation classes of streams. Several visual streams can run concurrently and exchange information between each other. The streams may initiate additional thought experiments, program them, and execute them in due course. The visual streams are focused employing the algorithm of “a child playing a construction set” that includes a visual model, a construction set, and the Ghost. Mosaic reasoning introduced in this paper is one of the major means to focusing visual streams in a desired direction. It uses analogy with an assembly of a picture of various colorful tiles, components of a construction set. In investigating role of mosaic reasoning in the Algorithm of Discovery, in this paper, I replay a series of four thought experiments related to the discovery of the structure of the molecule of DNA. Only the fourth experiment was successful. This series of experiments reveals how a sequence of failures eventually leads the Algorithm to a discovery. This series permits to expose the key components of the mosaic reasoning, tiles and aggregates, local and global matching rules, and unstructured environment. In particular, it reveals the aggregates and the rules that played critical role in the discovery of the structure of DNA. They include the generator and the plug-in aggregates, the transformation and complementarity matching rules, and the type of unstructured environment. For the first time, the Algorithm of Discovery has been applied to replaying discoveries not related to LG and even to mathematics.

Opis:

In the great century of Jewish migration, from the end of the eighteenth century into the 1920s, when over four million Jews left central and eastern Europe and headed for new lands, the humble, ubiquitous and despised occupation of peddling served as the vehicle which propelled them outward. Jews had peddled for centuries in Europe, as well as in the Muslim lands of the Ottoman Empire and in North Africa and it had a deep and complicated history as a pillar of Jewish economic life in these pre-migration settings. But its very nature played a crucial role in the ways in which Jews experienced their migration, encounter, and eventual settlement in the places to which they went. This paper looks at the connection between Jewish peddling and the great migration of the long nineteenth century when the locus of Jewish life shifted to the “new world,” the world opened up through European colonization and settlement.

Our solution to the problem of managing requirements is an embedded domainspecific language with Clojure playing the role of the host language. The requirements are placed directly in the source code, but there is an impedance mismatch between the compilation units and electronic documents, that are the major carriers of requirements information. This paper presents a coverage for this problem.

Process modelling is a very important stage in a Business Process Management cycle enabling process analysis and its redesign. Many sources of information for process modelling purposes exist. It may be an analysis of documentation related directly or indirectly to the process being analysed, observations or participation in the process. Nowadays, for this purpose, it is increasingly proposed to use the event logs from organization’s IT systems. Event logs could be analysed with process mining techniques to create process models expressed by various notations (i.e. Petri Nets, BPMN, EPC). Process mining enables also conformance checking and enhancement analysis of the processes. In the paper issues related to process modelling and process mining are briefly discussed. A case study, an example of delivery process modelling with process mining technique is presented.

Opis:

During the period of 60 years, the mining and metallurgical industry has been developed to such extent that Poland is now among the worlds’major producers ofcopper and silver. The discovery, made on 23 March 1957 by a team of specialists from the Geological Institute under the leadership of Jan Wyżykowski, was followed by the preparation of the first geological documentation of the copper deposit, containing the results ofpioneering works that laid the foundation for the knowledge of the Fore-Sudetic Monocline geology. This discovery marked the beginning of the recognition of the deposit and gave rise to further exploration for prospective areas elsewhere in SW Poland. Later studies of numerous drill cores strongly indicate that the Zechstein copper-bearing series contains a very large volume of prognostic, prospective and hypothetical resources, rimming the oxidized Rote Fäule areas also outside the Lubin-Sieroszowice Copper District. Extensive deep exploration drilling is required to verify the resource potential in several prospects. The long-term challenges demand new solutions for the mining industry of the future within the EU, to enable the reindustrialization of Europe.

Opis:

The turning point of Icelandic history was the reception of Christianity. After the discovery of the island, and then its settlement and the organization of an independent state, this was another step in the unification of the Icelandic nation. The circumstances of Iceland's acceptance of Christianity are peculiar in comparison with other countries in Europe at that time. While the decision to accept a new religion was usually made by the ruler, in Iceland the introduction of Christianity took place by the decision of the pagan parliament. Opposition to each other, the pagan and Christian factions, through reasonable negotiations, agreed in a bloodless manner on political agreement in this matter. The national assembly – Althingi – made a resolution in the summer of 1000 establishing a Christianity valid for the whole country religion. It is worth noting that pagan priest and clan leader Thorgeir Thorlaksson, played a crucial role here. Iceland was thus a country that was an exception to the European countries, which accepted a new faith through the conscious and voluntary decision of its inhabitants.

Jan Chryzostom Pasek

Opis:

Jan Chryzostom Pasek’s seventeenth-century Pamiętniki [Diaries] has to be regarded an important manuscript for Polish Romanticism. The significance of this text can only be rivalled by Macpherson’s songs of Ossian, the Dvůr Králové Manuscript, or the Poetic Edda, which is attested by a considerable number of editions of this Old-Polish ‘epic work’. The first printing of a substantial part of the text appeared in 1821 in Warsaw in the Astrea magazine. This publication contributed to the complex phenomenon of the Romantic turning point. Pasek’s Pamiętniki should be counted as the third beginning of Polish Romanticism, after Adam Mickiewicz’s Ballady i romanse (first volume of Mickiewicz’s Poezyje) and Antoni Malczewski’s Maria.

Opis:

The author presents and compares Maritain’s and Aquinas’s accounts of our discovery (1) of being as existing; and (2) of being as being (ens inquantum ens or the subject of metaphysics). He finds that especially in his final discussion of how one discovers being as being, Maritain’s account suffers greatly from the absence of any appeal to Aquinas’s negative judgment of separation and also from the omission of reference to the role of judgments of existence in one’s discovery of a premetaphysical notion of being. Wippel finds no evidence in Aquinas’s texts for Maritain’s defense of an intuition of being or of existence.

Opis:

Recently, mainly thanks to the creation of genomic sequences' databases of many organisms and invention of new technologies, rapid development of proteomics took place. Proteomics is the branch of modern molecular biology that deals with global analysis of proteins. A crucial part of this area of research is mass spectrometry, which allows sensitive, precise, fast and automated identification of single components of highly complex protein mixtures. Proteomic analysis is a multistage process that consists of sample collection and preparation, protein separation, their quantification and identification, and analysis of the collected data. One of the aims of proteomics is to identify biomarkers - specific indicators of defined biological processes. The biomarkers are extremely important from the medical point of view, since they can be applied as diagnostic parameters, or serve as aims of novel therapies. As cancer is still an unsolved problem of healthcare, many experiments have been conducted aiming at identification of biomarkers of these incurable illnesses.

Opis:

Greater emphasis must be placed on activities that promote innovative teaching methods in early childhood mathematics education in Poland. Our classrooms offer algorithmic and rote teaching methods, depriving students of important elements of successful mathematics learning. The aim of this action research was to investigate the relationship between a classroom environment that allows for dialogue and discovery and young children’s input into problem solving. Teaching six classes of elementary school within one academic year gave the author the opportunity to examine how dialogic teaching combined with a growth mindset approach can transform the attainment of knowledge, understanding and skills of learners, and how modern practices like number talks, solving open-ended tasks and group work can unleash students’ potential and activate them as thinkers and reasoners. The results confirmed that students who are challenged and offered concept-based learning opportunities not only genuinely engage in their tasks, but also help each other with deeper understanding of the concepts. They can cooperate with teachers in the creation of a new classroom in which students’ voices are heard and discoveries take place.

One reminds of the details concerning the discovery of trichinellosis by Zenker in 1860. After that a period of serious epidemics followed which caused panic everywhere. In course of time, however, the publiic opinion and even that of the sanitary authorities calmed down, partiailly due to the trust in the efficacy of trichinoscopy. Despite of numerous investigations on trichinellosis (over 2500 publications) and doubtless progresses in the prophylaxis the situation after 100 years did not much improve, at least in some countries. It 'is only since 25 years that more interest is shown in the problem of trichinellosis. One discovers the disease even there where it never had been recorded. Epidemics with a large extent (500 patients and more) happen frequently as well as lethal cases in families infected with the parasite. In spite of that, many cases still remain undiagnosed. One appeals to celebrate the 100th anniversary of the discovery of trichinellosis not only under the historical aspect but also as a symbol and indication to the unfavourable situation in many countries. One should propagandize investigations on a large scale, because we are still far even from knowing the actual frequency in occurrence of the parasite in the world. Perhaps the international conference to be held in Warsaw (12th and 13 th September, 1960) will be the turning point in starting an international co-operation in this field.

Opis:

The scope of historical transformation starting from 1492 could have been caused by the fact that Columbus’s voyages triggered off the process of re-defining rules and connections in the New World inhabited by various peoples. Important questions were raised: how to reconcile the variety of cultures and historical trajectories with a Christian impulse, and mainly with a universality of human values which could harmonize social relations with the variety of peoples and cultures, permeated by the power of otherness and inequality. Those issues brought about political and moral dilemmas for America’s conquerors. One can state that year 1492 symbolized an early dawn of our own era and many towns which were founded in America by Christopher Columbus and his successors became a symbol of struggle for justice, equality and peace for many nations, with memorable victories and failures, the majority of which have been too easily forgotten or ignored. But the most important sign of this significant year 1492 was kindling of the holy fire of the future, which gave hope to release a vital force of America’s peoples, regardless of their skin color and country of origin.

Opis:

The fossil remains of a hemichordate exoskeleton, recognized as fragments of the stolons and their cyst−like swellings connected with the fusellar zooidal tubes, were derived by chemical isolations from Late Permian (Kazanian) mudstones of the Svalis Dome (central Barents Sea, Norway). These fossils, referred to as Diplohydra szaniawskii sp. nov., are the first undoubted representatives of the class Graptolithoidea found in Permian deposits. The genus Diplohydra Kozłowski, 1959, known previously only from the Ordovician and originally established as a thecate hydroid taxon, is reinterpreted as an aberrant member of the order Rhabdopleuroidea. This strange hemichordate, characterized by fusellar tubes distinctly narrower than stolon−like tubes and their swellings, reveals a certain degree of dimorphism in the stolon system. D. szaniawskii sp. nov. also displays some peculiar morphological features common to the Ordovician rhabdopleuroid genus Rhabdopleurites Kozłowski and the stolonoid genus Stolonodendrum Kozłowski.

In 1925 Vladimir Mayakovsky travelled to America. He reached New York on July 30, 1925, meeting his readers, giving interviews and sightseeing. He also visited Cleveland, Detroit, Chicago, Philadelphia and Pittsburgh, where he read his poems, talked about the Soviet Union and shared his impressions of his US travel. His three-month stay (from the end of July 1925 to the end of October 1925) resulted in writing “Stichi ob Amierikie” and a travelog “Moje odkrytije Amieriki” (Moscow 1926), which many years later was also published in the Polish edition (Warsaw 1950).Mayakovski’s poems and reportage on America reflect his observational talent and brilliant sarcasm, which, however, are not devoid of ideology and propaganda.The poet, fascinated by modernization, mechanization and electrification, described the “country of dollar”, “car civilization”, standardization, prosperity and dynamic development, not without recognition and appreciation. At the same time he wrote critically, and sometimes maliciously, about such social problems of America of that time as racism, imperialism, etc.

Opis:

After World War II, Jan Wyżykowski studied at the Faculty of Mining University in Kraków. In 1946-1948, he held summer practices in mines and at the Polish Geological Institute (PGI), which allowed him to explore the ore deposits in Lower Silesia. On January 1951, he was transferred to the PGI, where all works related to the issues of the ore exploration were gradually taken over by the Ore Department based in Kraków. In the early 1950’s, a research program for copper exploration began to crystallize in the area located north of the Old Copper Basin and north of Wroclaw. Such program was postulated by two heads of the Ore Department, R. Krajewski and A. Graniczny. A seismic profile was acquired along the Boleslawiec-Glogów line to determine the extent of the Zechstein Kupeferschiefer formation in the Fore-Sudetic area. Wyżykowski was a planner ofthe drillings along this profile. Thefirst three boreholes did not indicate the possibility of success. What is more, Wyżykowski’s research was illegal, because he drilled to a depth of 700 metres, which was about 300 metres deeper than allowed. The thesis offutility of exploration in this area started to dominate. Despite all these adversities, Wyżykowski stubbornly strove to achieve the goal. A team led by him came across economic copper ore deposits on 23 March, 1957. In the Sieroszowice IG 1 borehole, at a depth of650 m, copper mineralization of 1.4% was found in marls. The presence of rich copper mineralization was confirmed also in a nearby borehole drilled in Lubin, S-19. The history of the "great Polish copper has started”.

Opis:

The knowledge discovery from real-life databases is a multi-phase process consisting of numerous steps, including attribute selection, discretization of real-valued attributes, and rule induction. In the paper, we discuss a rule discovery process that is based on rough set theory. The core of the process is a soft hybrid induction system called the Generalized Distribution Table and Rough Set System (GDT-RS) for discovering classification rules from databases with uncertain and incomplete data. The system is based on a combination of Generalization Distribution Table (GDT) and the Rough Set methodologies. In the preprocessing, two modules, i.e. Rough Sets with Heuristics (RSH) and Rough Sets with Boolean Reasoning (RSBR), are used for attribute selection and discretization of real-valued attributes, respectively. We use a slope-collapse database as an example showing how rules can be discovered from a large, real-life database.

Opis:

The historical development of scientific knowledge is examined in the context of research, and not, as tradition tells, in the context of justification. It is a story about experimental researches and theoretical investigations conducted in the years 1820-1902, which finally led to the discovery of electron, accompanied by methodological comments. Main results of the analysis are that knowledge is scientific if it has a systemic character, and experimental studies are scientific if they are systematic. „Systemic” means that studied objects or processes are assumed (a) to obey to the same laws, (b) if we know nothing about that the change of experimental situation can influence the given theoretical property of an object or process, than this property, determined in other successful applications of an accepted theory (i.e. the set of laws), should be attributed to objects or processes in new applications of the same theory. „Systematic” means that the same objects or processes are examined experimentally in a number of different, but interrelated, situations (so many as time, money and available laboratory instruments allow). I also try to show that in the historical growth of scientific knowledge hypotheses, understood as „free creations of the imagination”, do not play almost any role. Almost all theoretical discoveries are products of inferences that can be logically reconstructed and whose premises are (1) known and accepted laws of nature, (2) what is known about the studied objects on the basis of approved applications of these laws, (3) new experimental results. The moral of this is that theoretical discoveries appear if and only if the system of scientific knowledge is mature enough: it is impossible to draw conclusions, if you lack the necessary premises. A scientist cannot, by letting her imagination to run wild, to be ahead of her time, and if she tries to do that, she usually goes beyond the boundaries of science.

This research problem was a main incentive to add some development to the theory of association rules. The new form of quantitative and multi-dimensional association rules, unlike other approaches, does not require the discretization of real value attributes as a preprocessing step. They are discovered with data driven algorithm that gives precise and complete results and has polynomial complexity for a given dimensionality.

Opis:

Although the distribution of Asian crocodyliforms was extended northwards during the Paleocene–Eocene greenhouse world, the fossil record in northern Asia becomes scarce towards the end of the Eocene. We here report the first crocodyliform (an isolated tooth) from the upper Eocene Ergilin Dzo Formation of southeastern Mongolia, the mammalian fauna of which defines the Ergilian Asian Land Mammal Age. The conical non-recurved crown, the near complete root with the central resorption facet, and its late Eocene age suggest the crocodyliform affinity of the tooth. The current finding represents one of the northernmost occurrences of crocodyliforms in the upper Eocene of Asia (paleolatitude ca. 49°30’ N), and demonstrates that SE Mongolia probably met thermal requirements of crocodyliforms during the late Eocene.

Sustainable (and adaptive) management of natural resources is usually based on long term local experiences with nature. Local traditional communities often possess rich ecological knowledge connected to nature and traditional resource use and management. This knowledge can provide unexpected new information for researchers, and show new opportunities and ways for professionals in conserving rare and threatened species. We found significant new populations of the rare Ophrys lesbis in a private area next to the settlement of Çamlık, Muğla, and Orchis punctulata in the graveyard of Kadılar, Antalya with the help of local rural people. We firstly report the replanting of some orchid species (Orchis papilionacea, O. italica, and Barlia robertiana) in kitchen gardens of Çamlık and Bayır, in Muğla Province. The presence of significant orchid populations (e.g., the biggest ever found for Ophrys lesbis) in an area, where local owners have been actively harvesting salep from year to year for decades suggests that the moderate salep harvesting can be sustainable for long run. Based on our observations, Turkish salep harvesters can help botanists and conservationists find new locations of rare threatened orchid populations, and therefore indirectly help in conserve these populations.

Opis:

The first suite of epidosite from the Central Sudetic Ophiolites has been discovered in the sheeted dyke complex of the Mount Ślęża ophiolite (SW Poland). Epidosites from the Mount Ślęża ophiolite represent A-type epidosites which metasomatically replaced diabasic sheeted dykes of the Strzegomiany–Kunów Fe-Ti mineralisation zone. They form decimetre-scale elongated pistachio-green patches or veins within single dykes. Their composition (quartz + epidote + titanite) is analogue to Troodos ophiolite end-member epidosite of Cyprus. The pistacite content of epidote range from Ps16 to Ps31 and is similar to those from other ophiolitic epidosites. Titanite is low in Al2O3 (0.61 to 1.10 wt.%) and Fe2O3 (0.43 to 0.63 wt.%) and high in V2O5 (from 0.22 to 0.47 wt.%). The presence of epidosites in the Mount Ślęża ophiolite can be considered as an evidence of its supra-subduction zone (SSZ) affinity. Finally, a direct link between the epidosite formation and the release of base metals from its protolith (Cu, Zn and Co) indicates the possibility of the Cyprus-type volcanogenic massive sulphide deposit (VMS) formation in the Mount Ślęża ophiolite.

Opis:

Data integration is a crucial issue in the environments of heterogeneous data sources. At present, the afore-mentioned heterogeneity is becoming widespread. Based on various data sources, if we want to gain useful information and knowledge, we must solve data integration problems in order to apply appropriate analytical methods to comprehensive and uniform data. Such activity is known as knowledge discovery from the data process. Therefore, approaches to the data integration problem are very interesting and bring us closer to the “age of information”. This paper presents an architecture which implements knowledge discovery from the data process. The solution combines ETL technology and a wrapper layer known from mediated systems. It also provides semantic integration through connection mechanism between data elements. The solution allows for integration of any data sources and implementation of analytical methods in one environment. The proposed environment is verified by applying it to data sources in the foundry industry.

Opis:

Artykuł dotyczy odkrycia skarbu złotych monet w Zalewie (dawniej Saalfeld). Książę Prus, Albrecht Fryderyk, został o nim poinformowany przez starostę przezmarskiego (Preussisch Mark), który wysłał mu 144 monety w 1572 r. Starosta opisał również okoliczności odkrycia. W kancelarii książęcej określono je jako florentinische Guldtgulden, tj. „florenckie złote guldeny”. Autorzy twierdzą, że jest to opis pierwszego odkrycia złotych florenów w Zalewie. Podobny skarb zarejestrowano tam w 1991 r. Monety wysłane w 1572 r. przypuszczalnie stały się częścią kolekcji księcia Prus. Niektóre z florenów odnalezionych w 1991 r. zostały przekazane Muzeum Warmii i Mazur.
This article discusses the discovery of a hoard of gold coins in Zalewo (formerly Saalfeld). The duke of Prussia, Albrecht Frederick, was informed about the discovery by the Hauptmann of Przezmark (Preussisch Mark), who sent him 144 coins in 1572. The Hauptmann also described the process of how the coins were obtained. These coins were described by the archivist at the dukes‘s court as florentinische Guldtgulden – which means ”florentine gold florins“. The authors claim, that this is the first described discovery of gold florins from Zalewo. A similar discovery was recorded in Zalewo in 1991. The coins sent in 1572 possibly became a part of the collection of the Duke of Prussia. Some of the gold florins found in 1991 were donated to the Museum of Warmia and Mazury.

Opis:

Several problems related to work reliability appear while building service-oriented systems. The first problem consists of the lack of static typing and the lack of interservice data type checking. The second one consists of the high connectivity of services. The article shows an example of the strong and static polymorphic type system and the type check algorithm. The service-contract and the contract discovery concepts for universal service linking and type verification are described. After theoretic results had been realized in a service form, they were applied in practice in the real system, which improved its reliability. Also, technical realization decreased services connectivity, which promoted system quality increase. However, the increased complexity of the resulting system leveled advanced reliability.

We address one of the weaknesses of the RSA ciphering systems \textit{i.e.} the existence of the private keys that are relatively easy to compromise by the attacker. The problem can be mitigated by the Internet services providers, but it requires some computational effort. We propose the proof of concept of the GPGPU-accelerated system that can help detect and eliminate users' weak keys. We have proposed the algorithms and developed the GPU-optimised program code that is now publicly available and substantially outperforms the tested CPU processor. The source code of the OpenSSL library was adapted for GPGPU, and the resulting code can perform both on the GPU and CPU processors. Additionally, we present the solution how to map a triangular grid into the GPU rectangular grid \textendash{} the basic dilemma in many problems that concern pair-wise analysis for the set of elements. Also, the comparison of two data caching methods on GPGPU leads to the interesting general conclusions. We present the results of the experiments of the performance analysis of the selected algorithms for the various RSA key length, configurations of GPU grid, and size of the tested key set.

Opis:

The question stated in the title refers primarily to the awareness that there were indeed inspired writings, such as the First Letter to the Corinthians (cf. 1Cor 5:9), which is not even preserved in the oldest codes. To resolve this question you first need to provide answers to the following questions: What is the inspiration? How was the canon of the inspired books shaped? What is the Gospel and what is the difference between canonical and apocryphal gospels? There are important elements related to the inspiration that are meaningful to the discussed issues. Firstly, the revelation ended with the death of the last apostle. Secondly, the early Church became the norm of faith for the future generations. Thirdly, writing (especially letters) were written for a specific purpose. In the fourth place, the authorship of the Bible does not affect their inspired style. In the fifth place, the inspired books have a certain style and language that govern the rights of the times in which they arose. Taking into account all these elements we cannot deny the theoretical possibility of the discovery of the „disappeared” inspired writings, but an integral understanding of the revelation allows us to think of their possible finding that does not change in any way the content of revelation. In relation to the canon of the sacred books it seems to be a particularly important fact recalled by Benedict XVI in the Apostolic Exhortation Verbum Domini of inspiration, which was and is a deposit which the Church has received from God. This argument allows us to conclude that the Church, as the primary custodian of inspiration, provides comprehensive nature of revelation. Even if there was discovered some hitherto unknown letter, with all certainty inspired, it would not add anything new to the revelation that God had already revealed before. In relation to the gospel, we notice that there is only one, unchanged Gospel, and its content is the cross and resurrection of Christ (1Cor 15:3-5), that is the coming of the kingdom of God (Mark 1:14-15). In the canon of the New Testament books of the Bible there are four books, which we can define the literary genre of the concept of the gospel (Matthew, Mark, Luke and John). There are not, however, four separate versions of the message of the Good News but rather a slightly different view of the same reality of coming of the kingdom of God and its fulfillment in the cross of Christ and His resurrection. Such content cannot be found in the apocryphal gospels. There is therefore no basis for concern that it could come to the discovery of some sort of a letter that would change the way of looking at the reality of Jesus Christ and His art of saving.

This study proposes a sequential pattern mining algorithm to discover sequential patterns of Malaysia rainfall data for prediction. The apriori based algorithm is employed to find the sequential patterns from the time series data. The frequent episodes of rainfall sequences are discovered and classified by the expert into four main events namely, No rain, Light, Moderate and heavy. The sequential rules of ten rainfall stations from the duration of 33 years are analysed. The proposed algorithm is able to generate higher confidence and support of frequent and sequential patterns. Generally, the proposed study has shown its potential in producing methods that manage to preserve important knowledge and thus reduce information loss in weather prediction problem.

A fragment of clay figurine was found in a Band Pottery Culture pit at Lipnica near Szamotuły during rescue excavations o f the Y amai gas pipe ( 1996). It was probably painted and ornamented by vertically incised lines. Its compositional and formal attributes make us believe that this is a fragment of anthropomorphic, freestanding and realistically represented figurine without steatopygic features. It was either an early Neolithic idol or toy. The figurine shows similarities to alike artifacts from Central European oecumene of the Band Pottery culture (in particular in the Lower Silesia and Germany), which are characterized by their slenderness and incised ornamentation. Additionally, the painting decoration is indicative of influences from south-eastern centers of the LBK (Ukraine and Moravia).

Opis:

With the rapid popularization of mobile end-user electronic devices, wireless network technologies begin to play a crucial role as networks access technologies. While classic point-to-multipoint wireless access systems, based on fixed infrastructure of base stations providing access to clients, remain the main most popular solution, an increasing attention is devoted to wireless mesh systems, where each connecting client can extend overall resources of the network by becoming a network node capable of forwarding transit traffic. This ability results in severe reduction of the necessary network infrastructure, provides through coverage (thereby offering significant step towards ubiquity of network access) and offers massive redundancy. One of the most promising wireless mesh solutions currently being developed is an IEEE 802.11s standard, based on popular Wi-Fi technology. It combines low deployment costs with comprehensive suite of mechanisms able to operate a self-forming, autoconfigurable, dynamically extending, and secure mesh solution. However, despite its advantages, the standard lacks sufficient support for a number of functionalities, which can lead to significant inefficiency and degradation of service quality in real-world IEEE 802.11s network deployments. In the paper we propose a number of extensions of IEEE 802.11s mechanisms, designed to provide better service quality in case of real-world deployment scenarios, especially in case of large systems. Both propositions introduce modifications to mesh path discovery and interworking procedures, while retaining compatibility with standard solution. Their basic functionality and efficiency have been verified by means of simulation model in large-scale, self-organizing mesh structure. Subsequently they have been implemented and tested in real-world, access network testbed deployment. The results clearly indicate their utility, particularly in case of larger deployments of this network system type.

Opis:

In view of the characteristics of low speed mobile ship network, strong network dynamics and large signal interference, this paper proposes a low-rate mobile sensor network routing algorithm. In mobile wireless sensor networks, network topology changes frequently is a new challenge for resource constrained sensor node. Constantly updated network topology, sensor nodes need to exchange data frequently in order to maintain fresh route, resulting in sensor nodes consume a lot of energy. To solve this problem, to reduce control overhead is considered to be an effctive strategy. In this paper, we present a vector network-based dynamic routes (VNDR) scheme aims to minimize the control cost of the sensor nodes. We propose data exchange based on binary-coded vector address to reduce the control cost, moreover, we present a set of communication rules that govern the routes search procedure thereby requiring little cost of packet analysis to determine the next hop of node. VNDR performance was compared with well known scheme such as SPIN and DD. Simulation results show that, our VNDR scheme reduced the network control overhead and improved network lifetime.

Opis:

Traditional data mining methods based on rough set theory focus on extracting models which are good at classifying unseen objects. If one wants to uncover new knowledge from the data, the model must have a high descriptive quality---it must describe the data set in a clear and concise manner, without sacrificing classification performance. Rough modeling, introduced by Kowalczyk (1998), is an approach which aims at providing models with good predictive and descriptive qualities, in addition to being computationally simple enough to handle large data sets. As rough models are flexible in nature and simple to generate, it is possible to generate a large number of models and search through them for the best model. Initial experiments confirm that the drop in performance of rough models compared to models induced using traditional rough set methods is slight at worst, and the gain in descriptive quality is very large.

Opis:

Sphenothallus specimens are reported for the first time from the Mississippian of Central Russia. All Sphenothallus specimens have a phosphatic composition and a characteristic laminar structure, which is best observable in the thickened lateral parts of a tube. Most of the lamellae in the tube wall are straight, but some have a wavy morphology and a few are so wrinkled that they form hollow “ribs”. The wrinkled lamellae presumably had an originally higher organic content than the straight lamellae. There are borings on the surfaces of some lamel-lae that are similar in morphology to the bioerosional traces in various hard, biomineral substrates. Lamellae in the inner parts of the tube wall are composed of fibres. The fibres are parallel to the surface of the tube wall and in successive laminae they differ in orientation by irregularly varying angles. It is possible that the plywood micro-structure in Sphenothallus was originally organic and was later phosphatized during fossilization. An alternative, but less likely explanation is that the plywood structure was originally mineralized and therefore is comparable to the phosphatic lamello-fibrillar structures of vertebrates.

Opis:

The article shows the way in which the discovery of the existence of the Absolute is made in existential metaphysics. This existential metaphysics provides us with knowledge about reality. It shows the content of the experience of being, the content given to us in the transcendentals. It also unveils the foundation of the rational order, which is given to us in the discovery of the first principles of the existence of being and of cognition. Metaphysics provides us also with knowledge concerning the structure of being. It shows us being as composite and plural; being which is “insufficient” in its structure and calls for an explanation. That being—that is problematized in existence, given to us in experience, and incompletely intelligible in itself—lifts us toward its ultimate “complement” and understanding, to the Absolute.

Opis:

A knowledge discovery system is prone to yielding plenty of patterns, presented in the form of rules. Sifting through to identify useful and interesting patterns is a tedious and time consuming process. An important measure of interestingness is: whether or not the pattern can be used in the decision making process of a business to increase profit. Hence, actionable patterns, such as action rules, are desirable. Action rules may suggest actions to be taken based on the discovered knowledge. In this way contributing to business strategies and scientific research. The large amounts of knowledge in the form of rules presents a challenge of identifying the essence, the most important part, of high usability. We focus on decreasing the space of action rules through generalization. In this paper, we propose an improved method for discovering short descriptions of action rules. The new algorithm produces summaries by maximizing the diversity of rule pairs, and minimizing the cost of the suggested actions.

Tematy:

Opis:

The paper discusses the results of experiments with a new context extension of a sequential pattern mining problem. In this extension, two kinds of context attributes are introduced for describing the source of a sequence and for each element inside this sequence. Such context based sequential patterns may be discovered by a new algorithm, called Context Mapping Improved, specific for handling attributes with similarity functions. For numerical attributes an alternative approach could include their pre-discretization, transforming discrete values into artificial items and, then, using an adaptation of an algorithm for mining sequential patterns from nominal items. The aim of this paper is to experimentally compare these two approaches to mine artificially generated sequence databases with numerical context attributes where several reference patterns are hidden. The results of experiments show that the Context Mapping Improved algorithm has led to better re-discovery of reference patterns. Moreover, a new measure for comparing two sets of context based patterns is introduced.
