Opis:
Computing, in its usual sense, is centered on manipulation of numbers and symbols. In contrast, computing with words, or CW for short, is a methodology in which the objects of computation are words and propositions drawn from a natural language, e.g., small, large, far, heavy, not very likely, the price of gas is low and declining, Berkeley is near San Francisco, it is very unlikely that there will be a significant in crease in the price of oil in the near future, etc. Computing with words is inspired by the remarkable human capability to perform a wide variety of physical and mental tasks without any measurements and any computations. Familiar examples of such tasks are parking a car, driving in heavy traffic, playing golf, riding a bicycle, understanding speech and summarizing a story. Underlying this remarkable capability is the brain's crucial ability to manipulate perceptions - perceptions of distance, size, weight, color, speed, time, direction, force, number, truth, likelihood and other characteristics of physical and mental objects. Manipulation of perceptions plays a key role in human recognition, decision and execution processes. As a methodology, computing with words provides a foundation for a computational theory of perceptions - a theory which may have an important bearing on how humans make - and machines might make - perception-based rational decisions in an environment of imprecision, uncertainty and partial truth.

Opis:
Laser-matter interaction in rare gases (He, Ne, Ar and Xe) has been investigated using a 1 ps Nd-glass laser pulse at 1053 nm with intensities between 10$\text{}^{13}$ to 10$\text{}^{18}$ W/cm$\text{}^{2}$. Three aspects of the interaction have been studied: the creation of multiply charged ions, the energy of the ejected electron and the propagation in an underdense plasma. At the maximum laser intensity, all electrons of the outer shell are removed, except in Ne for which charge states up to 7+ are observed. Comparison of experimental data with Ammosov et al. tunneling model shows a very good agreement, indicating that ionization with a 1 ps pulse in the near infrared light mainly occurs in tunneling regime. Electrons created in a low-density medium with energies up to 5 keV have been detected. These energies are far above the energy acquired during the ionization process, indicating that at high laser intensities electron energy is governed by ponderomotive force. Finally, the study of the propagation of an intense laser pulse in an underdense plasma shows that it is not possible to obtain simultaneously high laser intensity (10$\text{}^{17}$-10$\text{}^{18}$ W/cm$\text{}^{2}$) and high electron density (10$\text{}^{19}$-10$\text{}^{20}$ cm$\text{}^{-3}$). Best conditions for solving this problem will be discussed.

Opis:
The shell of the coleoid cephalopod mollusc Kostromateuthis roemeri gen. et sp. n. from the lower Kimmeridgian of Central Russia consists of the slowly expanding orthoconic phragmocone and aragonitic sheath with a rugged surface, a weakly developed post-alveolar part and a long, strong, probably dorsal groove. The sheath lacks concentric structure common for belemnoid rostra. It is formed by spherulites consisting of the needle-like crystallites, and is characterized by strong porosity and high content of originally organic matter. Each spherulite has a porous central part, a solid periphery and an organic cover. Tubular structures with a wall formed by the needle-like crystallites are present in the sheath. For comparison the shell ultrastructure in Recent Spirula and Sepia, as well as in the Eocene Belemnosis were studied with SEM. Based on gross morphology and sheath ultrastructure K. roemeri is tentatively assigned to Spirulida and a monotypic family Kostromateuthidae nov. is erected for it. The Mesozoic evolution of spirulids is discussed.

Purpose: The paper presents the issues of designing the maintenance of materials and products in accordance with the idea of Industry 4.0. The author's views on the need for augmentation of the Industry 4.0 model were also presented, as well as the author's original concept that hybrid activities in predictive maintenance and condition-based maintenance should be preceded by designing material, maintenance & manufacturing 3MD at the stage of the product's material designing and technological designing. The 3MD approach significantly reduces the frequency of assumed actions, procedures and resources necessary to remain the condition of this product for the longest possible time, enabling it to perform the designed working functions. Examples of own advanced research on several selected, newly developed materials, used in very different areas of application, confirmed the validity of the scientific hypothesis and the relationship between the studied phenomena and structural effects and the working functions of products and their maintenance and indicated that material design is one of the most important elements guaranteeing progress production at the stage of Industry 4.0 of the industrial revolution. Design/methodology/approach: The author's considerations are based on an extensive literature study and the results of the author's previous study and empirical work. Each of the examples given required the use of a full set of research methods available to modern material engineering, including HRTEM high-resolution transmission electron microscopy. Findings: The most interesting intellectual achievements contained in the paper include presentations of the author's original concepts regarding the augmentation of the Industry 4.0 model, which has been distributed so far, which not only requires augmentation but is actually only one of the 4 elements of the technology platform of the extended holistic model of current industrial development, concerning cyber-IT production aided system. The author also presents his own concept for designing material, maintenance and manufacturing 3MD already at the stage of material and technological design of the product, eliminating many problems related to product maintenance, even before they are manufactured and put into exploitation. Detailed results of detailed structural researches of several selected avant-garde engineering materials and discussion of structural changes that accompanying their manufacturing and/or processing are also included. Originality/value: The originality of the paper is associated with the novelty of the approach to analysing maintenance problems of materials and products, taking into account the requirements of the contemporary stage of Industry 4.0 development. The value of the paper is mainly associated with the presentation of original issues referred to as findings, including the concept of augmentation of the Industry 4.0 model and the introduction and experimental confirmation of the idea by designing material, maintenance and manufacturing 3MD.

Opis:
In this paper, a reliability modeling approach for products with two performance characteristics related to two degradation processes is developed. The joint modeling of such processes is performed by using a copula function in order to consider the dependence structure between degradation processes. The proposed approach considers that different random effects affect the stochastic behavior of each performance characteristic. For such approach, different bivariate models with marginal gamma processes with heterogeneous random effects as marginal distributions are considered. As the random effects may differ between performance characteristics, different modifications of the structure of the parameters of the gamma process are proposed. Such that the random effects affect both the drift and diffusion, just the drift, and just the diffusion of the marginal gamma processes. The statistical inference of the joint bivariate models is performed via Bayesian approach. The obtained results show that a bivariate model with heterogeneous random effects has a slight better performance among the proposed models. Which implies that the bivariate heterogeneous random effects gamma process models may provide a better approach to model multivariate degradation data, and thus a better reliability assessment of the product under study.
W niniejszym artykule opracowano sposób modelowania niezawodności produktów posiadających dwa parametry użytkowe związane z dwoma procesami degradacji. Procesy takie można modelować łącznie wykorzystując funkcję kopuły, która pozwala na analizę struktury zależności między procesami degradacji. Proponowane podejście zakłada, że na stochastyczne zachowanie każdego z parametrów użytkowych wpływają różne efekty losowe. Przy takim założeniu, należy wziąć pod uwagę różne modele dwuwymiarowe, w których rozkłady brzegowe są brzegowymi procesami gamma z niejednorodnymi efektami losowymi. Jako że efekty losowe mogą być odmienne dla różnych parametrów użytkowych, zaproponowano różne modyfikacje struktury parametrów procesu gamma, takie, że efekty losowe wpływają zarówno na dryf jak i dyfuzję, tylko na dryf, lub tylko na dyfuzję procesów brzegowych gamma. Wnioskowanie statystyczne dla wspólnych modeli dwuwymiarowych przeprowadzono metodą Bayesa. Uzyskane wyniki pokazują, że dwuwymiarowy model z niejednorodnymi efektami losowymi ma nieznaczną przewagę nad pozostałymi zaproponowanymi modelami. Oznacza to, że dwuwymiarowe modele procesu gamma z niejednorodnymi efektami losowymi mogą stanowić lepszy sposób modelowania wielowymiarowych danych degradacyjnych, tym samym umożliwiając lepszą ocenę niezawodności badanego produktu.

Opis:
We consider a two-dimensional degenerate electron gas in the presence of perpendicular random magnetic field. The magnetic field disorder which is assumed to be Gaussian is characterized by two parameters. The first is proportional to the amplitude of local magnetic field fluctuations. The second one characterizes the disorder on the longer scale - we call it the screening length. Using the Kubo formula for the conductivity we have found a class of diagrams which leads to the long time tails in the current-current correlation function. For short times in comparison with the diffusion time corresponding to the screening length this function behaves like logarithm of time, for longer times it decays like t$\text{}^{-1}$ which of course brings into question the diffusive character of the behavior of the charged particle in random magnetic field widely assumed in the literature.

We study the identification of the nonlinearities A, vec{b} and c appearing in the quasilinear parabolic equation y_t - div (A(y) nabla y + vec{b} (y)) + c(y) = u in Omega x (0,T), assuming that the solution of an associated boundary value problem is known at the terminal time, y(x,T), over a (probably small) subset of Omega, for each source term u. Our work can be divided into two parts. Firstly, the uniqueness of A, vec{b} and c is proved under appropriate assumptions. Secondly, we consider a finite-dimensional optimization problem that allows for the reconstruction of the nonlinearities. Some numerical results in the one-dimensional case are presented, even in the case of noisy data.

Opis:
Deuterated monoclinic RbD$\text{}_{2}$PO$\text{}_{4}$ (DRDP) doped with chromium Cr$\text{}^{5+}$ is studied by EPR in 90 K to 400 K temperature range. EPR reveals two types of paramagnetic centers: single Cr$\text{}^{5+}$ (S = 1/2) complex and Cr$\text{}^{5+}$-Cr$\text{}^{5+}$ coupled pairs with effective spin S = 1. The EPR line splitting of single Cr$\text{}^{5+}$ complex in DRDP versus temperature agrees with the unit cell multiplication. The splitting of EPR line of pair spectrum appears at T* = 160 K, far below the phase transition temperatures and is due to the anisotropy of the exchange interaction. The clustering effect in the low-dimensional DRDP is suggested.

Opis:
The specific interactions between bovine serum albumin and poly- or two monoclonal bovine serum albumin antibodies were studied using force spectroscopy mode of atomic force microscopy. The histograms of the unbinding forces for polyclonal bovine serum albumin antibodies are broad at high antibody concentrations (50 or 270 μg/ml) and narrow at low concentrations (10 or 27 μg/ml), while the histograms for monoclonal antibodies peak at well defined unbinding force. The peak unbinding force depends on the type of antibody and the antibody concentration. In this paper we described and characterized the passive adsorption and covalent immobilization of proteins for tip and sample preparation. Force spectroscopy could serve as a useful method for characterization of antigen-antibody interactions for measuring the specificity of an antibody or to assess the purity of a monoclonal antibody solution and to distinguish between different antibodies.

Opis:
The purpose of this study is to develop a methodology for material design. This methogology will enabling the selection of production descriptors to ensure the required mechanical properties of structural steels specified by the designer of machinery and equipment. The selection is performed by using a computational model developed with use of artificial intelligence methods and virtual environment. The model is designed to provide impact examinations of these factors on the mechanical properties of steel only in the computing environment. Virtual computing environment allows full usage of the developed intelligent model of non-alloy and alloy structural steel properties and provides an easy, intuitive and user-friendly way to designate these properties for products after heat and plastic treatment. Also, very easy is the determination of chemical composition, treatment conditions and geometric dimensions on the basis of the steels mechanical properties. The proposed solutions allow the usage of developed virtual environment as a new medium in both, the scientific work performed remotely, as well as in education during classes. It is also possible the extension of this model to other groups of materials, not just for steel.

Opis:
A consistent particle filtering-based framework for the purpose of parallel face tracking and recognition from video sequences is proposed. A novel approach to defining randomized, particle filtering-driven local face features for the purpose of recognition is proposed. The potential of cumulating classification decisions based on the proposed feature set definition is evaluated. By applying cumulation mechanisms to the classification results determined from single frames and with the use of particle-filtered features, good recognition rates are obtained at the minimal computational cost. The proposed framework can operate in real-time on a typical modern PC. Additionally, the application of cumulation mechanisms makes the framework resistant to brief visual distortions, such as occlusions, head rotations or face expressions. A high performance is also obtained on low resolution images (video frames). Since the framework is based on the particle filtering principle, it is easily tunable to various application requirements (security level, hardware constraints).
