Opis:
This article presents R.S. Peters’ theory of moral education embedded in his broad conception of morality. The author examines Peters’ views against the background of Kohlberg’s stage theory of moral development; hence, the positions of both thinkers are interwoven throughout the discussion. It addresses some central issues relevant to moral education such as, for example: cognitive and affective aspects of morality, and the acquisition of virtues. In the article the author argues that Peters’ account of moral development and moral education provides supplementation for the somewhat narrow theory developed by Kohlberg, thus establishing a broader framework relevant to moral education.

Opis:
The concept of [r, s, t]-colourings was recently introduced by Hackmann, Kemnitz and Marangio [3] as follows: Given non-negative integers r, s and t, an [r, s, t]-colouring of a graph G = (V(G), E(G)) is a mapping c from V(G) ∪ E(G) to the colour set {1, 2,..., k} such that ‌c(vi) - c(vj)‌ ≥ r for every two adjacent vertices vi, vj, ‌c(ei) - c(ej)‌ ≥ s for every two adjacent edges ei, ej, and ‌c(vi) - c(ej)‌ ≥ t for all pairs of incident vertices and edges, respectively. The [r, s, t]-chromatic number Xr,s,t(G) of G is defined to be the minimum k such that G admits an [r, s, t]-colouring. In this paper, we determine the [r, s, t]-chromatic number for paths.

Opis:
Let $G$ be a plane graph. Two edges are facially adjacent in $G$ if they are consecutive edges on the boundary walk of a face of $G$. Given nonnegative integers $r$, $s$, and $t$, a facial $[r, s, t]$-coloring of a plane graph $G = (V,E)$ is a mapping $f : V \cup E \rightarrow {1, . . ., k} $ such that $ |f(v_1) − f(v_2)| \ge r $ for every two adjacent vertices $ v_1 $ and $ v_2 $, $ | f(e_1) − f(e_2)| \ge s $ for every two facially adjacent edges $ e_1 $ and $ e_2 $, and $ | f(v) − f(e)| \ge t $ for all pairs of incident vertices $ v $ and edges $ e $. The facial $[r, s, t]$-chromatic number $ \overline{ \chi }_{r,s,t} (G) $ of $ G $ is defined to be the minimum $k$ such that $G$ admits a facial $[r, s, t]$-coloring with colors $1, . . ., k$. In this paper we show that $ \overline{ \chi }_{r,s,t} (G) \le 3r + 3s + t + 1 $ for every plane graph $G$. For some triplets $ [r, s, t] $ and for some families of plane graphs this bound is improved. Special attention is devoted to the cases when the parameters $r$, $s$, and $t$ are small.

Opis:
The Fourth Dimension. R.S. Thomas’s Poetry and the Question of God’s AbsenceThe text deals with the poetry of R.S. Thomas (1913−2000) – a British author and an Anglican priest in the Church of Wales – whose works are full of controversial (given his priesthood) statements concerning the absence of God. As a lot of Thomas’s poems convey thoughts intersecting with post-secular reflection on the death of God, rooted in Derrida’s questioning of the “metaphysics of presence,” the article aims at tracing the inspirations behind Thomas’s quasi-religious poetry. The point of departure for this reflection is the poet’s recollection of being left by his parents alone for the first time. The impression of an empty house turns out to be an experience which shaped the poet’s attitude towards the disenchanted space he lives in. Although most critics claim that the apparent absence of God in Thomas’s poetry results directly from the tradition of theological via negativa, the author of the article pays attention to those characteristics which differentiate Thomas’s spirituality from the theological tradition and the most important difference between the poet’s attitude and the traditional model of Christian contemplation turns out to be time, or, more precisely, the temporal discrepancy between the possible accessibility of the transcendent being and the man’s ability to “catch it at work.”

Opis:
Na osnowie poliuretanów (PUR) zsyntezowanych z biokompatybilnych substratów wytworzono kompozyty z udziałem 2,5 lub 5,0 % mas. chitozanu. Segment sztywny poliuretanów otrzymano z alifatycznego 4,4'-diizocyjanianu dicykloheksylometanu i 1,4-butanodiolu, a segment giętki z polikaprolaktonodiolu i syntetycznego poli([R,S]-3-hydroksymaślanu), w stosunku masowym 90:10 lub 80:20. Twardość poliuretanów i ich kompozytów była typowa dla elastomerów stosowanych w medycynie. Na podstawie termogramów DSC stwierdzono, że wytworzone polimery były semikrystaliczne, a powierzchnia obserwowana pod mikroskopem optycznym wskazywała na strukturę heterogeniczną. Dodatek chitozanu do wytworzonych poliuretanów powodował zmniejszenie przepuszczalności pary wodnej, wpływając jednocześnie na zwiększenie sorpcji wody, natomiast nie zmienił sorpcji oleju.
Polyurethanes synthesized from biocompatible components were used to produce composites with 5 and 10 wt % chitosan content. The hard segments of polyurethanes were obtained from aliphatic 4,4'-methylene dicyclohexyl diisocyanate and 1,4-butanediol, while the soft segments were derived from polycaprolactonediol and synthetic poly([R,S]-3-hydroxybutyrate) in a weight ratio of 90:10 or 80:20. The hardness of polyurethanes and their composites with chitosan was typical for elastomers used in medicine. DSC thermograms showed that the investigated polymers were semicrystalline. The morphology of their surface observed under optical microscope was heterogeneous. The presence of chitosan in the composites reduced their water vapour permeability, resulting at the same time in an increased water sorption, while not influencing the oil sorption of polymer samples.

Opis:
Jakość regulacji jest kluczowym zagadnieniem w nowoczesnym przemyśle. Zadaniem inżyniera jest nie tylko dobór parametrów regulacji, ale również bieżące nadzorowanie jej jakości tak, aby maksymalizować wydajność procesu a także dbać o stan aparatury i urządzeń wykonawczych. W zdecydowanej większości rozwiązań praktycznych stosowany jest kwadratowy wskaźnik jakości, zarówno w procesie strojenia jak i oceny jakości regulacji. W artykule zostały zaproponowane inne wskaźniki, cechujące się większą odpornością. Zostały one zastosowane do dwóch zadań: projektowania nastaw regulatora oraz oceny jakości już pracującej struktury sterowania. W pracy uwzględnione zostały rozwiązania dla różnych wersji podstawowego algorytmu regulacji w przemyśle procesowym, tj. PID. Różne strategie regulacji PID zostały również porównane z algorytmem sterowania predykcyjnego typu MPC. Analiza symulacyjna wykorzystuje przemysłowy benchmark układu sterowania systemem chłodniczym wykorzystującym zjawisko kompresji pary.
Control quality is a crucial issue in modern industry. The engineer’s goal is to set control parameters and assess it constantly in order to maximize the efficiency of the process and watch the condition of actuators. The article describes a number of Control Performance Assessment indexes. They are applied to two tasks: controller tuning and the assessment of the quality of an already tuned control strategy. It presents a comparison between different indexes applied to various structures of the PID control algorithm. Finally the results are compared with Model Predictive Control. The analysis uses well known nonlinear industrial benchmark of a refrigeration system based on vapour compression.

Opis:
Today's world mainly focuses on reducing human effort and maximizing efficiency. Machines are replacing humans in many hazardous working environments. Automation is playing an important role in saving human efforts in most of their day-to-day works. A robotic vehicle has been developed in this project which can be particularly used in a small scale industry. The robotic vehicle is controlled by a mobile phone that is connected to the robot through a GSM network which acts as a remote controller. DTMF technology is used, which enables the robot to be controlled over the GSM network. The keypad of the mobile phone acts as a remote to control the vehicle's movement. The robotic vehicle developed is not an Automated Guided Vehicle (AGV) as an operator has to manually operate the vehicle. A sensor is attached to the front of the vehicle which senses obstruction in its path and enables the vehicle to avoid collisions with moving or fixed objects. The vehicle features battery powered motors and computer technology that has been programmed to drive to and from specific points. This research work involves the fabrication of a working model vehicle controlled over a GSM network using DTMF technology. The guided vehicle can work in environments such as transporting materials from a warehouse to production lines to reduce human effort and increase efficiency.

Opis:
A review of our today’s understanding of the ultimately broadband photonic Internet is presented. A simple calculation is presented showing the estimate of the throughput of the core photonic network branches. Optoelectronic components, circuits, systems and signals, together with analogous electronic entities and common software layers, are building blocks of the contemporary Internet. Participation of photonics in development of the physical layer in the future Internet will probably increase. The photonics leads now to a better usage of the available bandwidth (increase of the spectral efficiency measured in Bit/s/Hz), increase in the transmission rate (from Gbps, via Tbps up to probably Pbps), increase in the transmission distance without signal regeneration (in distortion compensated active optical cables), increase in energy/power efficiency measured in W/Gbps, etc. Photonics may lead, in the future, to fully transparent optical networks and, thus, to essential increase in bandwidth and network reliability. It is expected that photonics (with biochemistry, electronics and mechatronics) may build psychological and physiological interface for humans to the future global network. The following optical signal multiplexing methods were considered, which are possible without O/E/O conversion: TDM-OTDM, FDM-CO-OFDM, OCDM-OCDMA, WDM-DWDM. The Polish perspective closes the review.

This paper proposes a biometric system for authentication that uses the retina blood vessel pattern. The retina biometric analyzes the layer of blood vessels located at the back of the eye. The blood vessels at the back of the eye have a unique pattern, from eye to eye and person to person. The retina, a layer of blood vessels located at the back of the eye, forms an identity card for the individual under investigation. In particular retinal recognition creates an ”eye signature” from its vascular configuration and its artificial duplication is thought to be virtually impossible.

Opis:
This paper provides an overview of the research into the driver behaviour in simulated near collision situations. The aim of such investigations is to determine various parameters characterising the driver performance, e.g. driver response time. The driver response time is a very important parameter used, for example, to analyse road accidents. The results presented in this paper come from a study performed for two different emergency traffic situations using some predefined procedures (scenarios). The tests included situations in which a person driving a subject vehicle on a test track was to respond to obstacle mock-ups on a conflicting path (intrusion of a pedestrian from the left or from the right and intrusion of a vehicle from the right). The test data was used to determine the parameters describing the driver behaviour, i.e. the braking response time (braking manoeuvre), the steering response time (steering manoeuvre) and the intensity of the two manoeuvres. This paper compares the values of the driver response time for two scenarios, each with two variants. The average values of the braking response time and the steering response time were determined on a closed track in relation to the Time-To-Collision (TTC) in the range 0,6÷3s, characterising a near collision situation. Another parameter describing the driver behaviour discussed in this paper is the intensity of an avoidance manoeuvre. In the case of braking, the relative brake pedal displacement was analysed, while in the steering manoeuvre, the steering angle was taken into account. The average values of the braking displacement and the steering angle were presented in the function of the TTC. This paper looks at the relationship between the intensity of the driver response (braking, steering), the driver response time and the TTC.

Opis:
Free electron laser FELs are built in Europe mainly as nondependent infrastructures, or as a development of synchrotron ones. They are constructed mainly in centres which have considerable experience with synchrotron light sources of the third generation like DESY, Trieste, INFN, etc. Advances in very energetically efficient superconducting linear accelerators for electron beams, like TESLA type, caused an abrupt development of FEL machines all over Europe. New generation of FELs emits light beam of extreme intensity, good parameters, in IR, VIS, UV, EUV and X-ray spectral regions. The machine construction teams comprise also of young active researchers from Poland. In particular, these is a considerable participation of M.Sc. and Ph.D. students from Warsaw University of Technology at building of FLASH I, FLASH II, and EXFEL machines. Unique experiences gathered at work with these large experiments result in development of these young teams, and their further engagement in new initiatives: laser, laser - accelerator, inertial, plasma, plasma - energy, etc. This is what we observe with satisfaction. However, due to the lack of large research infrastructures in Poland, we are not members of the infrastructure owner clubs. Our young researchers may take part in the initiatives only indirectly as members of cooperative teams from the leading countries. As a further consequence, there is also a confined access of Polish laser and accelerator researchers to some kinds of European infrastructure development projects now under realization within the H2020.

Opis:
The most powerful now in the world, American X-ray laser LCLS (Linac Coherent Light Source), has been working as a research and user facility since 2009. It is further developed to LCLS II machine at the Stanford National Accelerator Laboratory SLAC in Menlo Park CA. In a certain sense, LCLS II is a response to the EXFEL machine and a logical extension of LCLS. All these machines are light sources of the fifth generation. EXFEL is expected to open user facility in 2016, at a cost of over 1 mld Euro. LCLS II, which design started in 2010, will be operational in 2017. The lasers LCLS, LCLS II and EXFEL use SASE and SEED methods to generate light and are powered by electron linacs, LCLS by a warm one, and EXFEL by a cold one. The linacs have energies approaching 20 GeV, and are around 2 - 3 km in length. EXFEL linac uses SRF TESLA microwave cavity technology at 1,3 GHz. A prototype of EXFEL was FLASH laser. SLAC Laboratory uses effectively over 50 years experience in research, building and exploitation of linear electron accelerators. In 2009, a part of the largest 3 km SLAC linac was used to build the LCLS machine. For the LCLS II machine a new infrastructure is build for two new laser beams and a number of experimental stations. A number of experts and young researchers from Poland participate in the design, construction and research of the biggest world linear and elliptical accelerators and FEL lasers like LCLS (Stanford), EXFEL (DESY) and CEBAF (JLab), and a few more. The paper concentrates on the development state-of-the-art of large laser infrastructure and its global and local impact, in the competitive world of R&D. LCLS infrastructure implications in Poland are considered.

Opis:
ILC machine–International Liner Collider, is one of two accelerators e+e-just under design and advanced consideration to be built with final energy of colliding electron and positron beams over 1 TeV. An alternative project to ILC is CLIC in CERN The ILC machine is an important complementary addition for the research potential of the LHC accelerator complex. The required length of ILC is minimally 30 km, but some versions of the TDR estimates mention nearly 50km. Superconducting RF linacs will be built using well established 1,3 GHz TESLA technology using ultrapure niobium or Nb3Sn resonant microwave cavities of RRR class, of ultimate finesse, working with gradients over 35MV/m, while some versions of the design mention ultimate confinement as high as 50MV/m. Several teams from Poland (Kraków. Warszawa, Wrocław – IFJ-PAN, AGH, UJ, NCBJ, UW, PW, PWr, INT-PAN) participate in the global design effort for this machine – including detectors, cryogenics, and SRF systems. Now it seems that the ILC machine will be built in Japan, during the period of 2016-2026. If true, Japan will turn to a world super-power in accelerator technology no.3 after CERN and USA. The paper summarizes the state-of-the-art of technical and administration activities around the immense ILC and CLIC machines, with emphasis on potential participation of Polish teams in the global effort of newly established LCC –The Linear Collider Consortium.

Opis:
Fusion, in all its varieties, is a very current subject of science and technology. The results of strongly exothermic reaction of thermonuclear fusion between nuclei of deuterium and tritium are: helium nuclei and neutrons, plus considerable kinetic energy of neutrons of over 14 MeV. DT nuclides synthesis reaction is probably not the most favorable one for energy production, but is the most advanced technologically. More efficient would be possibly an aneutronic fusion. The EU by its EURATOM agenda prepared a Road Map for research and implementation of Fusion as a commercial method of thermonuclear energy generation in the time horizon of 2050. The milestones on this road are tokomak experiments JET, ITER and DEMO, and neutron experiment IFMIF. There is a hope, that by engagement of the national government, and all research and technical fusion and plasma communities, part of this Road Map may be realized in Poland. The infrastructure build for fusion experiments may be also used for material engineering research, chemistry, biomedical, associated with environment protection, power engineering, security, etc. Construction of such research and industrial accelerator and tokomak infrastructure may have potentially a profound meaning for the development of science and technology in Poland.

Исследованы особенности инновационного развития в Украине в условиях усиления глобальной конкуренции. Проанализированы трансформационные изменения в развитии инвестиционно-инновационной среды в Украине, что дало возможность  определить реальное состояние инвестиционного климата и инновационной привлекательности нашей страны. Доказано, что на инновационную привлекательность Украины значительно влияет не только общее положение национальной экономики страны, но и условия ведения предпринимательской деятельности
The transformation of the economy of Ukraine predetermines the need for comprehensive analysis of its impact on the areas of economic activity because the depth of transformation processes has significant differences. In this regard especially important is innovation environment, on the development of which the competitiveness of the national economy largely depends, as well as the pace and quality of economic development. The analysis of the features of the transformational changes in the environment, especially in the innovation sector, is particularly relevant under conditions of global competition. The aim of the article is to study the development of global innovation environment, development and scientific substantiation of directions ensuring national innovation competitive advantages, to identify opportunities to use integration processes to enhance international innovation investment cooperation. To achieve this aim we applied the following methods: abstract–logical, structurally–logical, comparative and statistical. Peculiarities of innovation development in Ukraine under conditions of growing global competition were examined. We studied transformational changes in the development of investment and innovation environment in Ukraine, which made it possible to determine the real state of its innovation appeal. The innovative development was considered as self–reproductive basis for the formation of new patterns of economic dynamics, modernization of the national economy, technological convergence of Ukraine into global economic space, maintaining intellectual potential. The study of the transformation of innovative development and market transformation efficiency of social production showed that the innovation attractiveness of Ukraine is significantly affected not only by the general state of the national economy but by the conditions of business activities. The practical value of the research is in the fact that the implementation of the formulated strategic objectives in the innovation field will allow the national economy to solve the problem of substantial growth of the gross domestic product, to improve investment attractiveness, to create conditions for the development of existing and for attracting new companies, to create new sectors of the economy in the field of small and medium sized innovative businesses, to form the clusters of innovative enterprises, to ensure integration of science, government and business.  The issues of the transformation of innovative development will require further detailed study in the context of overcoming the crisis of competitiveness of the national economy, market transformations for the efficiency of social production.
Трансформація економіки України зумовлює необхідність всебічного аналізу її впливу на сфери економічної діяльності, оскільки глибина трансформаційних процесів має суттєві відмінності. У зв’язку з цим особливо важливе інноваційне середовище, від розвитку якого значною мірою залежить конкурентоспроможність національної економіки, темпи та якість економічного розвитку. Аналіз особливостей трансформаційних змін середовища, насамперед у інноваційній сфері України, особливо актуальний в умовах глобальної конкуренції. Мета статті полягає у дослідженні розвитку глобального інноваційного середовища, розробці та науковому обґрунтуванні напрямів забезпечення національних інноваційних конкурентних переваг, визначенні можливостей використання інтеграційних процесів для активізації міжнародного інноваційно-інвестиційного співробітництва. Для досягнення поставленої мети застосовано такі методи: абстрактно-логічний, структурно-логічний, порівняльний та статистичний. Досліджено особливості інноваційного розвитку в Україні в умовах посилення глобальної конкуренції. Вивчено трансформаційні зміни у розвитку інвестиційно-інноваційного середовища в Україні, що дало можливість визначити реальний стан її інноваційної привабливості. Інноваційний розвиток розглянуто як самовідтворювальну основу для формування нових моделей економічної динаміки, модернізації національного господарства, технологічної конвергенції України у світовий економічний простір, збереження інтелектуального потенціалу. Дослідження трансформації інноваційного розвитку та відповідності ринкових перетворень ефективності суспільного виробництва показало, що на інноваційну привабливість України значно впливає не лише загальний стан національної економіки, а й умови ведення бізнесу. Практичне значення дослідження полягає у тому, що виконання сформульованих стратегічних завдань у інноваційній сфері дозволить національній економіці вирішити питання забезпечення істотного росту валового продукту, підвищити інвестиційну привабливість, створити умови для розвитку сучасних і залучення нових великих компаній, створювати нові сектори економіки в сфері малого та середнього інноваційного бізнесу, сформувати кластери інноваційних підприємств, забезпечити інтеграцію науки, влади та бізнесу. Подальшого детального вивчення потребують питання трансформації інноваційного розвитку в контексті подолання кризи конкурентоспроможності національної економіки, відповідності ринкових перетворень ефективності суспільного виробництва.

Opis:
Although R.S. Peters is one of the founding fathers of the analytical paradigm in the philosophy of education, in this paper I develop his less known synthetic view on education. To that purpose, I explore Peters’ integrative view on the relationship between reason and passion (the emotions), his view on the levels of life, and even his view on religious education. What emerges from this exploration is the claim that Peters is, in an important sense, not a Kantian philosopher and the thesis that Peters’ work on the analysis and justification of education gets its ultimate inspiration from an anthropological and metaphysical background, which Ray Elliot identified as Peters’ Stoic attitude.

Opis:
In any complex system at temperature T the absorption cross-section and fluorescent power at a given photon energy are connected by a simple relation if the system is in thermal equilibrium while occupying one particular electronic excited state. Although this situation is impossible in principle because of finite excited-state lifetimes, it is often approximated to the extent that the simple relation, which is expressed as a linear function of energy with slope -1/k_{B}T, holds in a variety of cases. (The usual symbols for Boltzmann's constant and absolute temperature are used.) Observed deviations are of two principal kinds: a slope characteristic of some temperature T* other than ambient, and departures from a single pure straight line. The latter may include seemingly random variations and in some cases multiple regions of straight-line behavior. We have recently introduced an effective temperature T*(E), derived from the actual local slope of the putative straight line at energy E, which turns out to be a very sensitive detector of deviations from the ideal and, we believe, from equilibrium in the excited state. Plots of T*(E) display a variety of features. An anomaly in the T*(E) spectrum of chlorophyll a can be analyzed on this model, indicating a second weakly fluorescent state about 70 meV below the well-known Q_{y} band. The cases of chlorophyll and many others are included in a selective review of applications of the universal relation to fluorescent systems.

Opis:
Doppler broadening measurements performed by a slow positron beam on p-type Si samples implanted with He at 20 keV and at a fluence of 5×10$\text{}^{15}$ and 2×10$\text{}^{16}$ cm$\text{}^{-2}$ are reviewed and discussed. The evolution of the open volume defects distribution was studied as a function of isochronal and isothermal annealing of the samples. In the as implanted samples the majority of the open volume defects produced by implantation was passivated by He. The open volume defects density decreases, reaching a minimum at 250°C. In the 250-650°C temperature range there is an increase in defects due to the appearance of vacancy clusters. At the higher annealing temperatures (700-900°C) the vacancy clusters disappear only in the samples implanted at 5×10$\text{}^{15}$ cm$\text{}^{-2}$.

Light plays a key role in human’s life. Without light there will be no human life environment. Technologies based on light, called photonics, decide of the development of our civilization. The role of photonics is constantly increasing, especially in such fields as energy, education, agriculture and health. The UN has established the International Year of Light and Light - based Technologies – IYL2015 [1]. The organizers of IYL2015 events are professional organizations, communities, educational organizations, non-profit ones, technological clusters and platforms, but also private sector. The aim is to increase the social consciousness about the role of light and photonics in building of our civilization. This sort of recognition is necessary as a needed component of the development process of the society. Introduction of new technologies, like completely new kind of lighting, new diagnostic and therapeutic methods, new sources of energy, etc., must meet with social acceptance. In the opposite case, isolated development of infrastructure, will meet with obstacles. In Poland, the professional events, technical, trade fairs and outreach ones, are organized in the framework of the IYL2015 by Photonics Society of Poland, Polish Physical Society, Polish Platform of Photonics Technologies, etc. The paper summarizes the issues combined with the organization of the IYL2015 globally and in Poland. Extended version of this paper was published in Polish [2]. The paper is a part of a cycle of articles devoted to analysis of global processes of photonics development. Previous papers concerned initiatives Photonics21 in Europe [3-4], NPI – National Photonics Initiative in USA [5], and development of optical sciences in Poland [6-15].

Wide scale, European, infrastructural research projects on accelerator science and technology are under realization since 2003. CARE project was realized during the period 2003/4-2008, and next EuCARD during 2009-2013. Now during 2014-2017 there is successfully continued EuCARD² - Enhanced European Coordination of Accelerator R&D. European accelerator R&D community prepares next continuation of the EuCARD inside the Horizon 2020. The paper presents the work developments of EuCARD. Several institutions from Poland are participating in EuCARD: NCNR in Świerk, IChTJ, technical Universites in Łódź, Wrocław and Warsaw. Realization of the project during the last 12 years gave numerable and valuable results combined with essential modernization of the European research infrastructures. From the point of view of domestic interests, where we do not have large research infrastructures, the considerable benefits are associated with the participation of young researchers from Poland - engineers and physicists, in building of the top research infrastructures. Due to such participation, high technologies are developed in several centres in the country. The EuCARD project organizes annual meetings summarizing periodically the R&D advances. The EuCARD AM2015 was held in Barcelona in April.

Opis:
Science - research transformation of the Internet of Things (IoT) has a number of colours and shadows, many dimensions including technical, social, community, financial, economic and civilization. This transformation has many wide development roads but also numerable pitfalls and traps. It does not take place solely at the level of scientific and technical progress and innovation. It preliminarily takes place in a complex sociopolitical-economic context, narrowed for simplification as social acceptance and education only. Such acceptance, for example expressed simply by demand and market popularity, for simple items supplemented by useful functions, such as an iron that recognizes the type of fabric and matches its work accordingly, a completely autonomous vacuum cleaner, etc., is trivial. We aim at much deeper relations of IoT with society. If IoT were only adding such functionalities, it would not be worth the time to consider it here. IoT causes a lot of confusion for much more important reasons in many areas of life. Somewhere further on the potential paths of IoT development, it has been noted with interest, but also with anxiety, the possibility of its empowerment as local but also global, superintendent surveillance system, gathering enormous amounts of information, creating knowledge and making autonomous decisions. Potential subjectivity must include such attributes as acquiting from the creator, autonomy, consciousness, morality and further building by the society the whole legal system around the new entity. It will not be a single entity, it will be a whole virtual society, with electronic people. The consequences can be far-reaching and appear as an inevitable option on such a scale for the first time in the history of our human society. Overcoming certain barriers recognized by us may mean that the intelligence and consciousness are not only attributes of the human biological mind. Such reasoning, not without a reason, encounters strong resistance. However, there is a fundamental difference between the opposition to some genetic research and the potential modification of man himself, and the opposition to machine building, a system of superintendence that far exceeds the possibilities of a single man and of entire societies.

Opis:
В соответствующих опытах сравнивали 4 севооборота с разным участием картофеля (25, 50 и 75% и монокультура). Исследования охватывали два сорта картофеля: Сова и Тарпан. Материал для исследований отбирали после окончания первой ротации севооборотных опытов заложенных в 1976 г. после прохода посевных с учетом всех полей на бурых почвах хорошего ржаного комплекса. Предметом определений являлись почвенные образцы отобранные цилиндром в 1980 г после уборки растений со слоев 0-10, 10-20 и 20-30 см, из которых выделено, исчислено и идентифицировано фрукты и семена сорняков. Установлено, что по мере насыщения севооборота картофелем снижается запас Фруктов и семен сорняков в почве и беднеет их видовой состав. Особенно четко снижается число диаспор таких видов, как Scleranthus annuus, Polygonum convolvulus, Setaria glauca, Spergula arvensis, Rumex acetosella, Plantago maior, Polygonum avioulare.
Four crop rotations with different share of potatoes (25, 50, 75 and 100%) were compared in the respective experiments. Two potato varieties: Sawa and Tarpan, were tested. The material for investigations was taken after the first crop rotation in the experiment established in 1976 on brown soil of the good ryeland complex. The object of investigationss constituted soil samples taken into cylinders in 1980 after the harvest of crops from the 0-10, 10-20 and 20-30 layers. In the samples fruits and seeds of weeds were separated, counted and identified. It has been found that along with increasing share of potatoes in the crop rotation decreases the mass of fruits and seeds of weeds in soil and impoverishe their species composition. Particularly strongly decreases the number of diaspores of such weeds, as Scleranthus annuus, Polygonum convolvulus, Setaria glauca, Spergula arvensis, Rumex acetosella, Plantago maior and Polygonum aviculare.

Opis:
The Compact Muon Solenoid CMS is one of the major detectors of the LHC Large Hadron Collider accelerator. The second, a competitive brother, is Atlas. The accelerator complex in CERN was shut down for two years, after two years of exploitation, and will resume its work in 2015. During this break, called long shutdown LS1 a number of complex components, including electronics and photonics, will be intensely refurbished. Not only the LHC itself but also the booster components and detectors. In particular, the beam luminosity will be doubled, as well as the colliding beam energy. This means tenfold increase in the integrated luminosity over a year to 250fb⁻¹y. Discovery potential will be increased. This potential will be used for subsequent two years, with essentially no breaks, till the LS2 in 2017. The paper presents an introduction to the research area of the LHC and chosen aspects of the CMS detector modernization. The Warsaw CMS Group is involved in CMS construction, commissioning, maintenance and refurbishment, in particular for algorithms and hardware of the muon trigger. The Group consists of members form the following local research institutions, academic and governmental: IFD-UW, NCBJ- Świerk and ISE-WEITI-PW.

Opis:
W literaturze związanej z teorią inwestycji finansowych można spotkać wiele metod klasycznych i nieklasycznych, pozwalających na ocenę ryzyka. W grupie miar klasycznych znajdują się m.in. odchylenie standardowe czy też współczynnik zmienności. Miary te jednak na ogół zaniżają poziom ryzyka. W pracy zaprezentowano bardziej rzetelną miarę należącą do metod nieklasycznych, tj. wymiar fraktalny. Szacowanie tego wymiaru oparto na trzech procedurach: analizie R/S, metodzie segmentowo- -wariacyjnej oraz metodzie podziału pola. Badanie przeprowadzono dla finansowych szeregów czasowych złożonych z cen zamknięcia wybranych indeksów giełdowych oraz akcji spółek notowanych na GPW w Warszawie.
In the literature on the theory of financial investments can meet many classical and non-classical methods which allowing for risk assessment. In the group of the classical measures are the standard deviation or variation coefficient. However, these measures generally understate the level of risk. In the paper presents a more reliable measure of which belongs to the non-classical methods, ie. fractal dimension. This dimension was estimated based on the three procedures: R/S analysis, segment-variation method and field division method. The test will be conducted based on the financial time series which consist of closing prices of stock market indices and companies listed on the Warsaw Stock Exchange.

Opis:
Tailored, specialty optical fibres, made of complex glasses, called collectively as a non-telecommunications or instrumentation family, serve for various optical wave transformations for particular functional purposes and optical signal processing, rather than for long distance lossless and dispersionless, undistorted transmission. Research work on these fibres started during the late seventies of the last century in ITME/Warsaw and in Białystok University of Technology at the Faculty of Electrical Engineering. The initiator of this research at Glass Works Białystok [39] and Białystok University of Technology [4] was, then a very young engineer, Jan Dorosz. Over 35 years of development of the technological team, under his skilful management, resulted in a top laboratory which today does research at the cutting edge of the photonics science. The Białystok Optical Fibre Technology Laboratory (OFTL) is now a pearl in the crown of his Alma Mater. The paper opens this special issue of the PAS Bulletin on Technical Sciences, devoted to professor Jan Dorosz, and shows some of the developments in the area of optical fibre photonics, which were carried out at his active laboratory.

Opis:
W pracy przeprowadzono analizę wpływu zastosowania redukcji szumu losowego na poziom ryzyka inwestycyjnego mierzonego nieklasyczną miarą ryzyka, tj. wymiarem fraktalnym. Wymiar fraktalny jest jedną z charakterystyk dynamiki chaotycznej i bada, w jakim stopniu analizowany obiekt (szereg) wypełnia przestrzeń, w której jest zanurzony. W inwestycjach miara ta określa zmienność stopy zwrotu i im większa jej wartość, tym większe ryzyko związane z inwestowaniem w dany instrument finansowy. W celu wyznaczenia wymiaru fraktalnego zastosowano metodę segmentowo-wariacyjną i analizę R/S. W badaniach pod uwagę wzięto finansowe szeregi czasowe złożone z cen zamknięcia wybranych indeksów giełdowych oraz akcji spółek notowanych na GPW w Warszawie.
The paper analyzes the impact of the use of noise reduction on the level of investment risk, measured by a non-classical risk measure, i.e. the fractal dimension. The fractal dimension is one of the characteristics of chaotic dynamics and study the extent to which an object (series) fills the space in which it is embedded. In investments, this measure determines the volatility of the rate of return and the greater its value, the greater the risk associated with investing in a given financial instrument. The segment- -variation method and R/S analysis were used to determine the fractal dimension. The test will be conducted based on the financial time series which consist of closing prices of stock market indices and companies listed on the Warsaw Stock Exchange.

Opis:
Silent Life of Letters. On Interconnections between Language and Nature in the Poetry of R.S. Thomas. The essay sets out to explore R.S. Thomas’ (1913–2000) vision of the problematic relations between the man, the nature and their Creator. In the context of contemporary critique as well as the 20th century, post-husserlian philosophy, the author analyses Thomas’ cosmological poems and represents, on the one hand, the place that both man and God take in the creation and, on the other, the sacramental relationship between the human and the nature. What is important from this perspective is the material existence of both man and nature, which enables mutual infiltration that leads to discovery of imperceptible dimension of materiality, which, in turn, influences both human consciousness and language. This is why the author asks about the role of science in Thomas’ poetry and about the influence that “the machine” has on language and consciousness.

Opis:
The dynamic bone remodeling process is a computationally challenging research area that struggles to understand the actual mechanisms. It has been observed that a mechanical stimulus in the bone greatly affects the remodeling process. A 3D finite element model of a femur is created and a probabilistic analysis is performed on the model. The probabilistic analysis measures the sensitivities of various parameters related to the material properties, geometric properties, and the three load cases defined as Single Leg Stance, Abduction, and Adduction. The sensitivity of each parameter is based on the calculated maximum mechanical stimulus and analyzed at various values of probabilities ranging from 0.001 to 0.999. The analysis showed that the parameters associated with the Single Leg Stance load case had the highest sensitivity with a probability of 0.99 and the angle of the force applied to the joint of the proximal femur had the overall highest sensitivity.

Opis:
In the present paper, the axisymmetric boundary layer flow and heat transfer past a permeable shrinking cylinder subject to surface mass transfer is studied. The similarity transformations are adopted to convert the governing partial differential equations for the flow and heat transfer into the nonlinear self-similar ordinary differential equations and then solved by a finite difference method using the quasilinearization technique. From the current investigation, it is found that the velocity in the boundary layer region decreases with the curvature parameter and increases with suction mass transfer. Moreover, with the increase of the curvature parameter, the suction parameter and Prandtl number, the heat transfer is enhanced.

Opis:
An analysis is presented to investigate the unsteady magnetohydrodynamic (MHD) mixed convection boundary-layer flow of a micropolar fluid over a vertical wedge in the presence of thermal radiation and heat generation or absorption. The free-stream velocity and surface temperature are assumed to be oscillating in magnitude but not in the direction of the oncoming flow velocity. The governing equations have been solved by two distinct methods, namely, the finite difference method for the entire frequency range, and the series solution for low frequency range and the asymptotic series expansion method for the high frequency range. Numerical solutions provide a good agreement with the series solutions. The amplitudes of skin friction and couple stress coefficients are found to be strongly dependent on the Richardson number and the vortex viscosity parameter. The Prandtl number, the conduction-radiation parameter, the surface temperature parameter and the pressure gradient parameter significantly affect the amplitudes of skin friction, couple stress and surface heat transfer rates. However, the amplitudes of skin friction coefficient are considerably affected by the magnetic field parameter, whereas the amplitudes of heat transfer rate are appreciably changed with the heat generation or absorption parameter. In addition, results are presented for the transient skin friction, couple stress and heat transfer rate with the variations of the Richardson number, the vortex viscosity parameter, the pressure gradient parameter and the magnetic field parameter.

Nucleic acid content in different tissues in the freshwater fish N.notopterus in relation to sex was studied during Pre-spawning phase of the reproductive cycle. The fish were scarified and the tissues such as brain, liver, kidney and gonads removed and processed for determination of nucleic acids. It is observed that the nucleic acid content in different tissues of female fish has lower values than males. The results obtained in the present study may provide a contribution to the knowledge of the characteristics of nucleic acid as parameters of sexing the fish. The study also indicates that although male fish have higher values than female fish, both the sexes are biochemically and nutritionally better.

Opis:
The goal of mass customization is to make the products and / or services to satisfy individual customer who makes the order with a specific design for their needs. In real situation it is not so easy deal to meet individual design and to satisfy each customer separately; there is a need to accustom such environment to fulfill the market demand. In such situation, the decision makers are to ensure that they are following flexibility while taking orders and also dispatching them to the customers. One such idea is being developed in this research work. The main aim of this research work is to offer the procedure; flexible mass customization (FLMACUS) to make flexible schedules that meets the customer requirements. A simple heuristics is used to develop the procedure and Gantt charts are used for accommodating the jobs for meeting specific due dates. In this paper batch type Original Equipment Manufacturers (OEMs) are considered for our study purpose. The results from Gantt charts in various categories are depicted. Such types of Gantt charts are hardly found in earlier studies and the results show that this procedure (FLMACUS) is promising in nature to meet customer demands and due dates in a mass customized environment.
Celem masowej personalizacji jest sprawienie, aby produkty i / lub usługi satysfakcjonowały indywidualnego klienta, który dokonuje zamówienia zgodnego z konkretnym projektem odpowiadającego jego potrzebom. W rzeczywistej sytuacji nie jest łatwo znaleźć indywidualny projekt i zadowolić każdego klienta osobno; istnieje potrzeba przystosowania takiego środowiska do zaspokojenia popytu na rynku. W takiej sytuacji decydenci muszą upewnić się, że działają elastycznie przy przyjmowaniu zamówień i wysyłaniu ich do klientów. Taka koncepcja rozwinięta została w niniejszej pracy badawczej. Głównym celem badania jest zaproponowanie procedury; elastyczną masową personalizację (FLMACUS) do tworzenia elastycznych harmonogramów spełniających wymagania klientów. Do opracowania procedury wykorzystano prostą heurystykę, natomiast do dostosowania zadań do spełnienia określonych terminów posłużyły wykresy Gantta. W artykule do celów badawczych wzięto pod uwagę Producentów Oryginalnego Sprzętu (OEM). W kolejnej części artykułu przedstawiono wyniki z wykresów Gantta w różnych kategoriach. Tego typu wykresy Gantta prawie nie występują we wcześniejszych badaniach, a wyniki pokazują, że ta procedura (FLMACUS) ma charakter obiecujący, aby sprostać wymaganiom klientów i terminom w masowo dostosowywanym środowisku.

W artykule przedstawiono problem związany z ograniczeniem pola widoczności tzw. stref martwych w pojazdach użytkowych oraz pojazdach ciężarowych. Problem związany z bezpieczeństwem użytkowania takich pojazdów wiąże się w dużej mierze ze specyfiką konstrukcji samego nadwozia pojazdu oraz miejsca pracy kierowcy. Jednym ze sposobów poprawy widoczności z miejsca kierowcy jest wprowadzanie różnych układów techniki wizyjnej oraz systemów przekształcania obrazu z wykorzystaniem w technice samochodowej mini kamer. Jednym z najnowszych rozwiązań w tym zakresie jest „system 360 stopni” analizujący w pełnym zakresie otoczenie wokół pojazdu. System ten może w znaczący sposób poprawić bezpieczeństwo manewrowania poprzez całkowitą likwidację stref martwych widoczności.
The article presents the problem of limited field of view so. Blind spots in commercial vehicles and heavy goods vehicles. The problem of the safety of use of such vehicles is associated largely with the specifics of construction of the body of the vehicle and the driver's workplace. One way to improve visibility from the driver's seat is the introduction of different kinds of systems technology vision and image conversion system opened possibilities for use in automotive engineering mini-cameras. One of the latest solutions in this regard is the "system 360 degrees" fully analyzing the environment around the vehicle. This system can significantly improve the safety of maneuvering through the complete elimination of dead visibility.

Spectral methods constitute a useful tool in the analysis and synthesis of Boolean functions, especially in cases when other methods reduce to brute-force search procedures. There is renewed interest in the application of spectral methods in this area, which extends also to the closely connected concept of the autocorrelation function, for which spectral methods provide fast calculation algorithms. This paper discusses the problem of spectral decomposition of Boolean functions using the Walsh transform and autocorrelation characteristics.

Opis:
In this paper, we present an initial value technique for solving self-adjoint singularly perturbed linearvboundary value problems. The original problem is reduced to its normal form and the reduced problem is converted to first order initial value problems. This replacement is significant from the computational point of view. The classical fourth order Runge-Kutta method is used to solve these initial value problems. This approach to solve singularly perturbed boundary-value problems is numerically very appealing. To demonstrate the applicability of this method, we have applied it on several linear examples with left-end boundary layer and rightend layer. From the numerical results, the method seems accurate and solutions to problems with extremely thin boundary layers are obtained.
