Opis:
The paper seeks to elaborate on the competitive advantage of supply chains from the perspective of networking that is employed in a twofold sense. First, it is used to explore the issue of network competitive advantage, which is considered to deliver benefits to all major actors constituting the supply chains, while in the second sense networking is brought to demonstrate whether actors, as well as relationships formed by these actors, possess the necessary characteristics to deliver the network competitive advantage. Based on this conceptual reasoning, we then deliver theoretical propositions that assist in deeper understanding of how the network characteristics of supply chains can contribute to deriving the network competitive advantage of supply chains. Specifically, the study shows that most of these characteristics have a positive impact on the value of network rent. Likewise, the paper also points out that the specific characteristics of networking are mutually interdependent and remain in intermeshing and overlapping relationships. As a consequence, the independent variables, when considered holistically, may mutually interact in such a way that they may produce contradictory outcomes.

Opis:
The article describes that network mass media which appeared as a new type of discourse in the Russian-speaking sector of the internet - runet — morę than ten years ago are active- ly forming in the socio-cultural space of Russia. It mentions both generał features for the network and traditional mass media and specific ones characteristic only for network edi- tions, conditioned at first by technical possibilities of the internet (hypertextuality, inte- ractivity, multimediability, etc).The major content of the publication is connected with the display of speech epatage as the style dominant of the texts in network mass media. It is shown, for example, that the first phrase of the text (its peculiar headline-“hook”) is devoted arousing maximum inte- rest of the reader, to “hook” him and thus it is epatageous by its naturę, destination. Such a phrase tums out often to be units having both linguistic and cultural meaning, called lo- goepisystems or logoepisystemoids (transformed logoepisystems).The main idea of the article is that the traditional publicistic pathos of mass media has changed on the internet to the tonality of total irony and language gamę, resulting in the fact that the text is perceived as an enigma to be not only read, but rather unriddled.

Opis:
In this paper, we explore the relationship between the topological characteristics of a complex network and its robustness to sustained targeted attacks. Using synthesised scale-free, small-world and random networks, we look at a number of network measures, including assortativity, modularity, average path length, clustering coefficient, rich club profiles and scale-free exponent (where applicable) of a network, and how each of these influence the robustness of a network under targeted attacks. We use an established robustness coefficient to measure topological robustness, and consider sustained targeted attacks by order of node degree. With respect to scale-free networks, we show that assortativity, modularity and average path length have a positive correlation with network robustness, whereas clustering coefficient has a negative correlation. We did not find any correlation between scale-free exponent and robustness, or rich-club profiles and robustness. The robustness of small-world networks on the other hand, show substantial positive correlations with assortativity, modularity, clustering coefficient and average path length. In comparison, the robustness of Erdos-Renyi random networks did not have any significant correlation with any of the network properties considered. A significant observation is that high clustering decreases topological robustness in scale-free networks, yet it increases topological robustness in small-world networks. Our results highlight the importance of topological characteristics in influencing network robustness, and illustrate design strategies network designers can use to increase the robustness of scale-free and small-world networks under sustained targeted attacks.

Opis:
The article presents the methodology for measuring verification of the phenomenon of fades in the DAB+ SFN. The verification is related to comparing the characteristics of the fades determined theoretically with the occurring fades in the real environment of a large city. The conditions favorable for the occurrence of fading are presented and by selecting the appropriate propagation analysis tool, the places where the occurrence of fading is most likely were selected. In these places an analysis of the characteristics of fades was carried out and the conditions for their verification were determined.

Opis:
Subnetwork with two nodes shared with entire ventilation network can be separated as its part. For the network under common ventilation conditions, one of these nodes will become the subnetwork starting node, while the other will be the subnetwork end node. According to the graphs theory, such a piece of the network can be considered as a subgraph of the graph representing the entire ventilation network. A special feature of that subgraph is lack of predecessors of the subnetwork starting node and lack of successors of the subnetwork end node. Ventilation district of a mine may be often treated as a subnetwork. Vicinity is a part of the network which is not separated as subnetwork. In the case of a ventilation district its vicinity forces air flow through the district. The alternative characteristic curve of the vicinity can therefore be compared to the characteristics curve of a fictional fan that forces the airflow in the district. The alternative characteristics (later in the text: the characteristics) of the vicinity of the ventilation district in an underground mine strongly influence air quantity and therefore play a crucial role in the reduction of methane, fire and thermal hazards. The role of these characteristics and proper selection of their approximating function were presented in the article. The reduction of resistance of an intake stopping (having influence on entire resistance of a ventilation district) produces increased airflow in the district. This changes of airflow in the district caused by a variation in internal resistance (e.g. by opening an internal regulation stopping) depends on the characteristic of the vicinity of the district. Proper selection of its approximating function is also important for this matter. The methods of determination of the alternative characteristic curve of the district vicinity are presented. From these procedures it was possible to obtain the results of air quantities and differences in isentropic potentials between an inlet and an outlet to/from the ventilation district. Following this, the characteristics were determined by graphic and analytic methods. It was proved that, in contrast to flat vicinity characteristics, steep ones have a smaller influence on the airflow modification in the district (which are caused by a regulation of the district resistance). The characteristic curve of the vicinity determines the ability to regulate air quantity and velocity in the district.

Opis:
W artykule przedstawiono problemy modelowania wybranych właściwości warstw, otrzymywanych w procesach osadzania powłok metodami PAPVD. Analizie zostały poddane powłoki nanoszone z wykorzystaniem dwóch różnych komercyjnych urządzeń. Technika modelowania została zastosowana w celu opracowania modeli, pozwalających na prognozowanie właściwości warstw na podstawie parametrów procesu osadzania. W procesie modelowania, z zastosowaniem metody sztucznych sieci neuronowych, zostały wykorzystane zbiory danych z eksperymentów badawczych i procesów technologicznych. Przeprowadzone badania pozwoliły na opracowanie modeli tylko dla niektórych z analizowanych charakterystyk, głównie ze względu na występujące niedostatki w zbiorach danych. Wpłynęło to zasadniczo na organicznie możliwości opracowania modeli. Należy jednak podkreślić, że uzyskane w trakcie badań wyniki uzasadniają zastosowanie sieci neuronowych do opisu badanych procesów i budowy modeli prognostycznych.
Some of the properties of coatings deposited with the use of PAPVD methods were described. The research concerns coatings deposited on two different commercial devices. The modelling technique was applied in order to model development that enables the prediction of layer properties based on the deposition parameters. In this research, the method of artificial neural network was applied for modelling, and data from both research experiments and technological processes were used. As the results of modelling show, only some characteristics were well described by models. That problem mainly appeared because of data shortage causing a limitation in modelling. However, research results justify neural network application for describing the analysed processes and the development of prediction models for coating properties.

Opis:
Certain critical infrastructure networks show some interconnections, relations and interactions with other ones, most frequently when located and operating within particular areas. Failures arising within one critical infrastructure network, can then negatively impact not only on associated systems, societies and natural environment, but also on mutual critical infrastructure networks. Therefore, interdependent critical infrastructure networks can be determined as network of critical infrastructure networks (network of networks approach). The paper presents safety analysis of the network of critical infrastructure networks, taking into account interconnections, relations and interactions between particular ones. Critical infrastructures networks as multistate systems are considered, by distinguishing subsets of no-hazards safety states, and crisis situation states, and by analysing transitions between particular ones. Issues introduced in the article are based on the assumption that one key critical infrastructure network impacts on functioning of other critical infrastructure networks - can reduce their functionality and change level of their safety and inoperability, furthermore, other networks can impact each other, too. Safety characteristics of network of critical infrastructure networks: safety function, mean values and standard deviations of lifetimes in particular safety state subsets, are determined, taking into account interdependencies between particular networks. The results are related to various values of coefficients defining the significance of influence of interdependencies among networks.

Opis:
The article presents torque characteristic of the engine in dynamic operating conditions as a function of engine speed and throttle opening angle. All mentioned parameters are analyzed as independent variables over time. To develop such a characteristic an artificial neural network is used. The training data were obtained from measurements carried out on the test bench on SI engine. The operating states reflect all possible configurations of these parameters, which may occur during use of the vehicle in real traffic conditions. The article shows design of an artificial neural network that allows to designate the required dependences. Moreover, it describes the fit of the model to the measurement data, which clearly indicates its correctness. Then the developed characteristic in dynamic states is compared with the characteristic in static working states. The differences between them for selected cases of engine operation states are presented. It shows the versatility of the presented method.

The principles are established by means of a Thomistic metaphysics of the One and the Many, i.e., the Thomistic teaching of the opposition between Unity and Multiplicity. It is this Thomistic metaphysical philosophical science that studies the distinct kind (genus) of an organization and its specific common sense principles of organizational leadership. This common sense leadership is a harmonious blending of psychology, ethics and operational behavior.

Opis:
The paper analyses the possibilities of using the forest soil descriptions included in the forest management plan to draw up an initial characterization of the area in terms of their usefulness for the forest road building. That kind of data may be used in the planning of forest road network in preliminary location concept of road sections. Knowledge in the subject of the spatial distribution of ground with specific physical properties enables us to offer such options, that are likely to ensure the stability of built facilities and also lower costs of implementation and operating as well as reduce the environmental costs of the investment. The paper shows the possibilities and ways to determine the basic characteristics of the ground, such as: the type of ground, filtration coefficient and vulnerability to frost heave. Forest soil descriptions based on macroscopic studies should be regarded as insufficient. Use of the soil data is possible and gives the desired effect only when the results of the grain size analysis can be used. On the basis of these data, classification of the ground can be performed and one can determine the basic indicators of the suitability of the tested materials. We used twelve soil samples with the diverse texture (10−89% sand, 7−83% silt and 4−29% clay). On the basis of complete pedological data collected in accordance with the recommendations of the Forest Management Instruction, it was possible to classify the material in terms of engineering and calculation of relevant indicators and characteristics. It should be noted that this is the initial characteristics of the soil and as such it is not a substitute for detailed research required for the execution stage of the project of specific road sections.

Opis:
Badanie cech jakościowych ma coraz większe znaczenie ze względu na ustalenie ceny skupu oraz ze względu na dalsze przeznaczenie nasion. Po wejściu Polski do Unii Europejskiej surowce i produkty końcowe muszą sprostać wymogom stawianym przez pozostałe kraje członkowskie. Ważnym problemem współczesnego rolnictwa zrównoważonego jest produkcja nasion oraz produktów o odpowiednich parametrach jakościowych. Dotychczasowe badania dowodzą, że zarówno technologia zbioru, warunki transportu i suszenia a także przechowywanie wywierają wpływ na jakość nasion, warunkując ich przydatność dla przemysłu. Zadaniem przemysłu zbożowego jest, oprócz przetwórstwa, także odpowiednie zabezpieczenie w czasie magazynowania, aby zachować odpowiednie właściwości i walory smakowe nasion. W związku z tym istnieje konieczność ciągłej kontroli produktów jak również surowców magazynowanych. Przemysł rolno - spożywczy dysponuje jedynie metodami opartymi na ocenie sensorycznej, wykorzystującej narządy zmysłu. Metoda ta jest bardzo czasochłonna i pracochłonna. Poszukiwanie innowacyjnych metod pozwala na wdrożenie do przemysłu rolno - spożywczego technik opartych na komputerowej analizie obrazu i sztucznych sieci neuronowych. Założono zatem, że korzystając z komputerowej analizy obrazu oraz przygotowanej w tym celu aplikacji do przetwarzania i analizowania pozyskanych obrazów cyfrowych, wykorzystując model rozpoznawania barw RGB, pozwoli na szybkie uzyskiwanie wyników. Ma to znaczenie w czasie skupu zbóż do magazynów, w celu określenia wstępnej jakości przyjmowanych nasion pod względem zanieczyszczeń, co w konsekwencji prowadzi do ustalenia ceny skupowanego materiału. Drugim aspektem wykorzystania tej metody jest kontrola jakości przechowywanego ziarna w magazynach. Opracowanie takiej metody pozwoli na szybkie uzyskanie wyników z pominięciem czasochłonnych prac laboratoryjnych. Dodatkowym elementem pracy jest porównanie metody tradycyjnej z metodą komputerowej analizy obrazu. Do porównania wykorzystano sztuczne sieci neuronowe.
Examination of qualitative characteristics becomes more and more important for fixing purchase price and due to further use of seeds. Following Poland accession to the European Union, raw materials and final products must meet requirements set by other member states. An important issue in modern sustainable agriculture is the production of seeds and products possessing suitable qualitative parameters. Studies completed to date prove that harvesting technology, transport and drying conditions, and storage affect seeds quality, thus conditioning their usability for industry. Besides processing, grain industry is expected to provide adequate protection during storage so as to ensure suitable properties and taste quality of seeds. As a result of this, it is necessary to provide continuous control of products and stored materials. Agricultural and food industry has at its disposal methods based on sensory assessment only, using sense organs. This method is highly timeconsuming and labour absorbing. Search for innovative methods allows to introduce techniques based on computerised image analysis and artificial neural networks in agricultural and food industry. It has been assumed then that using computerised image analysis and specially prepared for this purpose application for processing and analysis of obtained digital images with help of the RGB colour identification model will allow to obtain results quickly. This is important when purchasing grain for stores in order to determine initial quality of accepted seeds as regards impurities, which consequently leads to determining purchased material price. Another aspect of using this method is quality control for grain kept in stores. Development of such method will allow to obtain results quickly, omitting time-consuming laboratory works. An additional element in this paper is comparing conventional method to computerised image analysis method. Artificial neural networks have been used for comparison.

Opis:
In the article a queueing network (QN) with positive customers and a random waiting time of negative customers has been investigated. Negative customers destroy positive customers on the expiration of a random time. Queueing systems (QS) operate under a heavy-traffic regime. The system of difference-differential equations (DDE) for state probabilities of such a network was obtained. The technique of solving this system and finding mean characteristics of the network, which is based on the use of multivariate generating functions was proposed.
