Opis:
Dobrobyt społeczno-ekonomiczny to pojęcie złożone, które nie ma w literaturze precyzyjnego i jednoznacznego określenia, stąd trudności jego pomiaru. Wielu polityków, ekonomistów, międzynarodowe instytucje i media próbują wykorzystywać produkt krajowy brutto, czy też do- chód narodowy, jako miernik dobrobytu. Jest to podejście niewłaściwe, gdyż jeden i ten sam miernik nie może poprawnie charakteryzować dwóch różnych merytorycznie agregatów – produk- cji i dobrobytu. W badaniach spoleczno-ekonomicznych podejmowane są próby wprowadzenia alternatywnych, czy też komplementarnych w stosunku do PKB mierników dobrobytu. Trwają poszukiwania formuły, stąd pomiar dobrobytu społeczno-ekonomicznego jest otwartym proble- mem badawczym. Głównym celem referatu jest zaprezentowanie próby pomiaru dobrobytu spo- łeczno-ekonomicznego z wykorzystaniem modelowania miękkiego. W pierwszej części referatu zaprezentowane będą rozważania na podstawie literatury o spo- sobach definiowania i pomiaru dobrobytu społeczno-ekonomicznego. Jednym ze nich jest opraco- wany w ramach Programu Narodów Zjednoczonych d.s. Rozwoju (United Nations Development Programme) wskaźnik rozwoju społecznego HDI (ang. Human Development Index). Wskaźnik HDI jest oparty na trzech podstawowych czynnikach: poziomie zdrowotności, poziomie wykształ- cenia oraz dostępności dóbr materialnych, które decydują o powiększaniu zdolności i możliwości człowieka. Inne podejście jest stosowane w ramach koncepcji trwałego i zrównoważonego rozwo- ju, która zakłada poprawę jakości życia współczesnych i przyszłych pokoleń oraz wskazuje po- trzebę przewartościowania celów rozwojowych z materialnych na niematerialne. Koncepcja zrów- noważonego rozwoju podkreśla trzy aspekty rozwoju: społeczeństwo, gospodarkę i środowisko naturalne, przy czym to ten ostatni element jest bardzo mocno podkreślany. Założenia trwałego i zrównoważonego rozwoju uwzględnione są przy konstrukcji wskaźnika trwałego dobrobytu ekonomicznego ISEW (ang. Index of Sustainable Economic Welfare), bądź jego modyfikacji wskaźnika autentycznego rozwoju GPI (ang. Genuine Progress Indicator). Druga część referatu będzie poświęcona zastosowaniu do badania dobrobytu społeczno- ekonomicznego modelowania miękkiego. Metoda ta pozwala na badanie powiązań między zmien- nymi ukrytymi (niemierzalnymi), czyli zmiennymi nie mającymi jednoznacznych odpowiedników wśród zmiennych obserwowalnych (mierzalnych). W oparciu o opis teoretyczny budowany jest model, który wyjaśnia kształtowanie się wartości badanej zmiennej ukrytej poprzez zależności z jej indykatorami (zmiennymi mierzalnymi), a także poprzez związki z innymi zmiennymi ukry- tymi. W badaniu dobrobytu społeczno-ekonomicznego, oprócz aspektu materialnego, muszą być uwzględnione korzyści wynikające z ochrony zdrowia oraz edukacji. W modelu przyjęto, że do- brobyt społeczno-ekonomiczny jest zależny od poziomu rozwoju gospodarki i jakości środowiska naturalnego. Zbudowany model miękki ma posłużyć do analizy dobrobytu społeczno- ekonomicznego w krajach Unii Europejskiej.

Opis:
The article discusses the development of an approximation model of selected plastic and mechanical properties obtained from compression tests of model materials used in physical modeling. The use of physical modeling with the use of soft model materials such as a synthetic wax branch with various modifiers is a popular tool used as an alternative or verification of numerical modeling of bulk metal forming processes. In order to develop an algorithm to facilitate the choice of material model to simulate the behavior of real-metallic materials used in industrial production processes the induction of decision trees was used. First of all, the Statistica program was used for data mining, which made it possible to determine / find the relationship between the percentage of particular constituents of the model material (base material and modifiers) and yield strength, critical and maximum strain, and provide the opportunity to indicate the most important variables determining the shape of the stress - strain curve. Next, using the induction of decision trees, an approximation model was developed, which allowed to create an algorithm facilitating the selection of individual modifying components. The last stage of the research was verification of the correctness of the developed algorithm. The obtained research results indicate the possibility of using decision tree induction to approximate selected properties of modeling materials simulating the behavior of real materials, thus eliminating the need for costly and time-consuming experiments carried out on metallic material.

Opis:
In order to analyze the influential factors of soft foundation settlement in a marine reclamation land project, the consolidation settlement and pore pressure dissipation of the entire area are numerically simulated using Soft-SoilCreep Model, in which the PLAXIS finite element software for professional geotechnical engineering is applied and empirical data of Japanese Kansai’s airport project are used. Moreover, the figures of settlement and pore pressure results in the different basic period are drawn, and the corresponding analysis conclusions are obtained based on the comparison among the results from the computational parameters of depth. In addition,, the influence rules of various parameters on settlement results is concluded through running the parameter sensitivity analysis in Soft-Soil-Creep Model, and the experience and conclusions can be for reference in the design and con-struction of similar large-scale marine reclamation land project. Also the empirical value method of the creep index has not been applied widely. Further research needs to be done.

Opis:
The paper presents the results of the magnetoelastic Villari effect modelling in high-permeability Mn0.51Zn0.44Fe2.05O4 ferrite. Modelling was performed on the basis of measurements of magnetoelastic characteristics of frame-shaped samples. For the modelling, the corrected Jiles-Atherton-Sablik model was used. On the base of modelling results, the stress dependence of parameter k and stress-induced anisotropy were estimated. As a result the changes of saturation magnetostriction of Mn0.51Zn0.44Fe2.05O4 ferrite subjected to stresses were calculated. Such changes were previously observed experimentally. However, the phenomenon of stress-induced sign change of saturation magnetostriction was never previously explained quantitatively.

Opis:
Time dependence of soft soils has already been thoroughly investigated. The knowledge on creep and relaxation phenomena is generally available in the literature. However, it is still rarely applied in practice. Regarding the organic soils, geotechnical engineers mostly base their calculations on the simple assumptions. Yet, as presented within this article, the rate-dependent behaviour of soft soils is a very special and important feature. It influences both the strength and the stiffness of a soil depending on time. It is, thus, significant to account for time dependence in the geotechnical design when considering the soft soils. This can result in a more robust and economic design of geotechnical structures. Hence, the up-to-date possibilities of regarding creep in practice, which are provided by the existing theories, are reviewed herein. In this article, we first justify the importance of creep effects in practical applications. Next, we present the fundamental theories explaining the time-dependent behaviour of organic soils. Finally, the revision of the existing constitutive models that can be used in numerical simulations involving soft soils is introduced. Both the models that are implemented in the commercial geotechnical software and some more advanced models that take into account further aspects of soft soils behaviour are revised. The assumptions, the basic equations along with the advantages and the drawbacks of the considered models are described.

Zawarte w tytule pojęcie bogactwo narodów, zapożyczone od Adama Smitha, jest wystarczająco pojemne, by pomieścić określenia pokrewne, które pojawią się w dalszych rozważaniach: arystotelesowską obfitość środków potrzebnych dla domu i państwa, marksowski społeczny produkt globalny oraz współczesne dochód narodowy i produkt krajowy brutto. Jedne oznaczają, co prawda, cały zasób dóbr i usług, inne – okresowe przyrosty tego zasobu, ale wszystkie mieszczą się w pojęciu bogactwo narodów. Zamierzam wyjaśnić, jaki typ badań stosowano, aby napełnić te określenia odpowiednią treścią, ile stuleci pochłonęły badania i jak kolejne sztafety pokoleniowe przekazywały rezultaty badań swoim następcom. Przypuszczam, że uda się to osiągnąć w ramach modelu B+R, który tym razem wykorzystany będzie na szlaku innowacji miękkich.
The wealth of nations, an idea borrowed from Adam Smith’s work, is a notion broad enough to include many similar concepts such as Aristotle’s abundance of means needed by the home and state, Marx’s social global product and modern meanings of national income and gross domestic product. Some denote the total amount of goods or services, whereas others describe the seasonal growth of that amount, but they all fit into the notion of the wealth of nations. My aim was to explain which research methods were utilized in order to assign a specific meaning to this idea, for how many centuries the problem has been studied, and how each generation passed the results of their research to their successors. My analyses are based within the framework of the R&D model, in this case used in relation to soft innovations.

Opis:
While the Slope Fault Model method can solve the soft-fault diagnosis problem in linear analog circuit effectively, the challenging tolerance problem is still unsolved. In this paper, a proposed Normal Quotient Distribution approach was combined with the Slope Fault Model to handle the tolerances problem in soft-fault diagnosis for analog circuit. Firstly, the principle of the Slope Fault Model is presented, and the huge computation of traditional Slope Fault Characteristic set was reduced greatly by the elimination of superfluous features. Several typical tolerance handling methods on the ground of the Slope Fault Model were compared. Then, the approximating distribution function of the Slope Fault Characteristic was deduced and sufficient conditions were given to improve the approximation accuracy. The monotonous and continuous mapping between Normal Quotient Distribution and standard normal distribution was proved. Thus the estimation formulas about the ranges of the Slope Fault Characteristic were deduced. After that, a new test-nodes selection algorithm based on the reduced Slope Fault Characteristic ranges set was designed. Finally, two numerical experiments were done to illustrate the proposed approach and demonstrate its effectiveness.

Gravity can play a tremendous effect on deformation of rubberlike materials and biological soft tissues. In this paper, considering the gravity effect, we proposed a surface Green’s function of a soft elastomer based on the neo-Hookean model. The proposed surface Green’s function is applied to analyze the elastic deformation of a soft elastomer subjected to uniform pressure. The surface normal displacement of the soft elastomer is calculated and the results show that gravity has a large impact on the surface deformation of the elastomer. Generally, the surface normal displacement decreases with the increasing gravitational force.

Opis:
Magnetic hysteresis occurs in most electrical engineering devices once soft ferromagnetic materials are exposed to relatively high temperatures. According to several scientific studies, magnetic properties are strongly influenced by temperature. The development of models that can accurately describe the thermal effect on ferromagnetic materials is still an issue that inspires researchers. In this paper, the effect of temperature on magnetic hysteresis for ferromagnetic materials is investigated using a self-developed numerical method based on the Preisach distribution function identification. It employs a parameter depending on both temperature and the Curie temperature. This approach is of the macroscopic phenomenological type, where the variation of the magnetization (in direct connection with the Preisach triangle) is related to the observed macroscopic hysteretic behavior. The isotropic character of the material medium is predominant. The technique relies on a few experimental data extracted from the first magnetization curve provided by metallurgists. The ultimate goal is to provide a simple and robust magnetic behavior modeling tool for designers of electrical devices. Temperature is introduced at the stage of identifying the distribution function of the Preisach model. This method is validated by the agreement between the experimental data and the simulation results. The developed method is very accurate and efficient in modeling the hysteresis of ferromagnetic materials in engineering particularly for systems with ferromagnetic components and electromagnetic-thermal coupling.

Opis:
In order to properly understand the effect of freezing-thawing circle (FTC) to mechanical behavior of costal soft soil (CSS), unconfined compressive test is conducted. Six kind FTC times are designed from zero to five. The tested data show that: (1) unconfined compressive strength of CCS decreases nonlinearly with more FTC, and the strength after five FTC times becomes about 22% of its original strength without any freezing-thawing experience; (2) stressstrain curves of all unconfined compressive samples can be well fitted by three-parameter hyperbolic model; (3) and relationship between two parameters and FTC times can be fitted by exponent function, while another parameter can be considered as 0.95. Consequently, one composite hyperbolic- exponent empirical formula is established in order to describe freezing-thawing-dependent stress-strain behavior of CSS. Finally, good agreements have been found between tested dada and simulated results.

The aim of the study was an estimation of the possibility of using hyperelastic material models to fit experimental data obtained in the tensile test for the swine skin tissue. Methods: The uniaxial tensile tests of samples taken from the abdomen and back of a pig was carried out. The mechanical properties of the skin such as the mean Young’s modulus, the mean maximum stress and the mean maximum elongation were calculated. The experimental data have been used to identify the parameters in specific strain-energy functions given in seven constitutive models of hyperelastic materials: neo-Hookean, Mooney–Rivlin, Ogden, Yeoh, Martins, Humphrey and Veronda–Westmann. An analysis of errors in fitting of theoretical and experimental data was done. Results: Comparison of load –displacement curves for the back and abdomen regions of skin taken showed a different scope of both the mean maximum loading forces and the mean maximum elongation. Samples which have been prepared from the abdominal area had lower values of the mean maximum load compared to samples from the spine area. The reverse trend was observed during the analysis of the values of elongation. An analysis of the accuracy of model fitting to the experimental data showed that, the least accurate were the model of neo- -Hookean, model of Mooney–Rivlin for the abdominal region and model of Veronda–Westmann for the spine region. Conclusions: An analysis of seven hyperelastic material models showed good correlations between the experimental and the theoretical data for five models.

Opis:
The article argues that the current security model was shaped in a long period. It is shown that the system was shaped by the solutions applied after the II WW, what embraces global and regional solutions. Until the end of the Cold War the applied solutions were assigned to two opposite Blocs: Western and Eastern. After 1989, which is considered to be the symbolic turning point and end of the Cold War, part of the states from the former Eastern Bloc, after introducing market and democratic reforms have joined NATO and the EU. This also included three states created after the dissolution of the former SU. The article states also that security in Europe is challenged by attempt to reconstruct the area of Russian influence. At the same time it states that this process is not limited to voluntary access of the former republics of SU but also includes annexation of the territories of sovereign Ukraine. The article illustrates that the contemporary security system is characterized by strong asymmetry of applied solutions. NATO applies liberal, cooperative solutions, while Russia uses solutions build upon force and military potential. This asymmetry and moves undertaken by Russia undermine the solutions introduced by international laws. They resulted introduction of sanctions by the US and EU states, what was followed by some political and military steps, labelled as boost NATO military presence in the NATO states bordering with Russia. The article states that in parallel to Hard Power, NATO and the EU should apply also Soft Power. Solutions applied in Russia follow the feeling of majority people in Russia who experience the trauma of former superpower and its fall. The article describes basic conditions of security system with its global and regional solutions, which create its current determinants. This concerns the level of military spending, economic potential, as well as weight of individual states and their groupings in the world scene.
