W artykule przedstawiono problem wymiany danych pomiędzy komputerem pokładowym i systemem nawigacji lądowej TALIN. Komputer pokładowy wozu bojowego z zainstalowanym oprogramowaniem jest narzędziem wspomagającym dowodzenie. Jednym z podstawowych źródeł informacji dla tego komputera jest system nawigacji, który ciągle przesyła dane nawigacyjne potrzebne oprogramowaniu zainstalowanemu na tym komputerze. W celu zapewnienia automatycznej komunikacji pomiędzy komputerem i systemem nawigacji zostało w WITU opracowane specjalne oprogramowanie spełniające rolę interfejsu, które łatwo się implementuje i jest bardzo proste w użyciu.

Andrzej Pitrus discusses complex relationships between the two worlds – art and computer/ games. Numerous artists are looking for inspirations in the world of an interactive entertainment, yet some of them are creating new paths of its development. Some of the artists focus on new and unique interfaces. Others refer to the mechanics of games to create their own interactive works. Bill Viola’s The Night Journey is an excellent example of such project. The author also reviews critical games, which are based on the mechanisms easily found in commercial games. Yet, their goal is to deconstruct them, rather than followig well known tracks. Pitrus examines this strategy in the works of a famous studio “Tale of Tales”.

The strain-rate effects on the interaction between a matrix crack and an elliptic inclusion in granule composites under dynamic tensile loadings are investigated numerically. It is found that the crack deflection/penetration behavior depends on the relative strength and local curvature of the interface as well as the loading-rate (or strain-rate). For a certain interfacial strength, there exists a critical strain-rate above which the crack can penetrate across the interface; otherwise, the crack deflection occurs. Moreover, the critical strain-rate is found to be dependent only on the local curvature of the interface near the crack tip regardless of the size and shape of the elliptic inclusions.

W pracy przedstawiono rezultaty symulacji numerycznych wpływu szybkości zmian stanu naprężenia na interakcje pomiędzy szczeliną w osnowie i eliptycznym wtrąceniu w kompozycie granulkowym poddanym dynamicznemu obciążeniu rozciągającemu. Stwierdzono, że odkształcenie i (lub) penetracja szczeliny zależy od względnej wytrzymałości oraz lokalnej krzywizny powierzchni kontaktu pomiędzy wtrąceniem a osnową. Wykazano także ich zależność od tempa zmian obciążenia (lub odkształcenia). Zauważono, że przy pewnym poziomie wytrzymałości powierzchni kontaktu pojawia się krytyczna wartość tempa zmian odkształcenia, powyżej której szczelina propaguje w poprzek powierzchni kontaktu, w przeciwnym razie ugina się. Zgodnie z wynikami badań, krytyczna wartość szybkości zmian odkształcenia okazała się zależna wyłącznie od miejscowej krzywizny powierzchni kontaktu przy wierzchołku szczeliny, bez względu na rozmiar i kształt eliptycznego wtrącenia.

In this study, stainless steel 316L and Inconel 625 alloy powders were additively manufactured by using directed energy deposition process. And heat treatment effect on hardness and microstructures of the bonded stainless steel 316L/Inconel 625 sample was investigated. The microstructures shows there are no secondary phases and big inclusions near interfacial region between stainless steel 316L and Inconel 625 except several small cracks. The results of TEM and Vickers Hardness show the interfacial area have a few tens of micrometers in thickness. Interestingly, as the heat treatment temperature increases, the cracks in the stainless steel region does not change in morphology while both hardness values of stainless steel 316L and Inconel 625 decrease. These results can be used for designing pipes and valves with surface treatment of Inconel material based on stainless steel 316L material using the directed energy deposition.

We describe an innovative computer interface designed to assist annotators in the efficient selection of segmentation solutions for proper tagging of Sanskrit corpora. The proposed solution uses a compact representation of the shared forest of all segmentations. The main idea is to represent the union of all segmentations, abstracting from the sandhi rules used, and aligning with the input sentence. We show that this representation provides an exponential saving, in both space and time. The segmentation methodology is lexicon-directed. When the lexicon does not have full coverage of the corpus vocabulary, some chunks of the input may fail to be recognized. We designed a lexiconacquisition facility, which remedies this incompleteness and makes the interface more robust. This interface has been implemented, and is currently being applied to the annotation of the Sanskrit Library corpus. Evaluation over 1,500 sentences from the Pañcatantra text shows the effectiveness of the proposed interface on real corpus data.

This paper presents the framework for executing Cahn-Hilliard simulations through a web interface which is based on a popular continuous integration tool called Jenkins. This setup allows launching computations from any machine, in the client mode, and without the need to sustain a connection to the computational environment. It also isolates the researcher from the complexity of the underlying infrastructure and reduces the number of steps necessary to perform the simulations. Moreover, the results of the computations are automatically post-processed and stored upon job completion for future retrieval in the form of raw data, a sequence of bitmaps, as well as a video sequence illustrating changes in the material structure over time. The Cahn-Hilliard equations are parameterized with mobility and chemical potential function, allowing for several numerical applications. The discretization is performed with Isogeometric finite element method, and it is parameterized with the number of time steps, the time step size, the mesh size, and the order of the B-spline basis functions using for the approximation of the solution. The interface is linked with the alternating direction semi-implicit solver, resulting in a linear computational cost of the simulation.

Wykorzystujemy do tego popularne narzędzie służące do ciągłej integracji o nazwie Jenkins. Tego typu konfiguracja pozwala na uruchamianie obliczeń z dowolnej maszyny w trybie klienckim bez konieczności utrzymywania połączenia do środowiska obliczeniowego. Dzięki temu naukowiec wykonujący obliczenia jest odizolowany od skomplikowanej infrastruktury obliczeniowej, a uruchomienie symulacji wymaga mniejszej liczby czynności. Ponadto, wyniki symulacji są automatycznie przetwarzane i prezentowane w formie tabularycznej, sekwencji bitmap oraz filmu, który odzwierciedla zmiany zachodzące w strukturze badanego materiału w czasie. Równania Cahna-Hilliarda są parametryzowane poprzez funkcje mobilności i potencjału chemicznego, co pozwala na przeprowadzanie symulacji wybranych zjawisk dla wielu materiałów. Dyskretyzacja jest wykonywana z wykorzystaniem Izogeometrycznej Metody Elementów Skończonych i jest uzależniona od liczby i rozmiaru kroków czasowych, wielkości siatki oraz rzędu krzywych B-sklejanych, użytych do aproksymacji rozwiązania. Interfejs, o którym mowa, konfiguruje solwer zmienno-kierunkowy z dyskretyzacją czasową schematem wprost, co skutkuje liniowym kosztem obliczeniowym symulacji.

The contribution subject is the adhesive forces at the solid-liquid interface study. The adhesive forces effect is characterized by so called surface energy. On the Victor Kaplan department of fluid engineering there is installed a special device for the surface energy measurement. By this device usage will be presented the surface energy measurement results of different surfaces used in the hydraulics and aeronautics. On the result base will be derived the dissipative function rate of these materials in reference to glass. This rate represents the hydraulic losses. Moreover it'll be set the new boundary condition for the partial slip (partial wettable) surfaces.

The interface between vacuum deposited C60 fullerene films and layers of mimetic liquid crystals (LC), such as pentylcyanobiphenyl (5??) or the BL055 mixture has been studied. In order to understand the processes of barrier formation at the C60 /LC interface, the kinetics of the dark current, short-circuit photocurrent and photo voltage caused by short pulses of light (~60 sec, hv = 1.88 eV) were investigated. Initial barrier height at the ?60 /LC interface and its increase caused by ion diffusion to electrodes under the action of an internal electric field or light are determined. A fast component of the short-circuit photocurrent and photo voltage was observed. This component was probably due to the presence of a partly filled acceptor-like deep electron level associated with an interaction between C60 molecules and oxygen. The occupancy of the local states depends on molecular interactions at the interface. Their effect on the processes of ionic polarization and depolarization is discussed.

Theoretical studies of interface impact on structural properties of InAs/GaSb type-II superlattices were carried out. Multilayer structures used for mid-infrared detection were considered. The superlattices examined consisted of 190 pairs of 9 monolayers (MLs) of InAs and 10 MLs of GaSb. Both types of interfaces, i.e., "GaAs-like" as well as "InSb-like", were analyzed. The simulations were performed using dynamical theory of diffraction for different thicknesses of interface layers. The lattice mismatch was extracted from X-ray diffraction profiles. The analysis performed shows that the strain-balanced InAs/GaSb superlattice can be optimized by using thin InSb-like or GaAs-like interface layers simultaneously.

The structure of Ceria doped Scandia Stabilized Zirconia (1Ce10ScSZ) electrolyte film deposited by EB-PVD (Electron Beam-Physical Vapour Deposition) technique on NiO-ZrO2 substrate was characterized by electron microscopy. The highly porous substrate was densely covered by deposited film without any spallation. The produced electrolyte layer was of a columnar structure with bushes, bundles of a diameter up to 30 ?m and diverse height. Between the columns, delamination cracks of few microns length were visible. The annealing of zirconia film at 1000 °C resulted in its densification. The columnar grains and delaminating cracks changed their shape into a bit rounded. High magnification studies revealed nanopores 5-60 nm formed along the boundaries of the columnar grains during annealing. High-quality contacts between the electrolyte film and anode substrate ensured good conductivity of the electrolyte film and high efficiency of SOFC.

In the paper by Chattopadhyay and Rajneesh (2006, "Reflection and refraction of waves at the interface of an isotropic medium over a highly anisotropic medium", Acta Geophysica, vol. 54, no. 3, pp. 239-249), the authors proposed a process to calculate R/T (reflection and transmission) coefficients at the interface between isotropic and triclinic half-spaces, with incident qP waves in triclinic media. Unfortunately, besides several misprints, the authors made a fatal assumption that there is no transmitted SH wave generated in isotropic media, which led the successive analytical derivations and numerical calculations thoroughly wrong. In this paper, the errors are analyzed at length and corrections are given. Then an alternative approach to solve the problem is proposed and numerical results are shown and discussed.

Currently all modern car combustion engines are equipped with an electronic control device, sometimes called on-board computer. It is responsible for driving the engine depending on driver behavior, engine working conditions and engine load. Main loads an Electronic Engine Control (EEC) unit is empowered to control are injectors (to doze certain amount of fuel) and ignition system (to ensure ignition timing). The control decision is estimated on the basis of readings from various sensors like MAP (Manifold Air Pressure) Sensor, CKP (Crankshaft Position) Sensor, air temperature sensor, throttle position and many others. Treating the EEC unit as a black box with specific inputs and outputs, an engine simulator was be constructed. Its principle is to substitute real sensors with compatible artificial electrical signals, arrange them in patterns similar to typical engine working conditions, expose EEC to them and eventually measure how EEC changes output signals values in real-time. The purpose behind was to create a fixture for educational purposes. Its operator can easily manipulate with virtual throttle pedal, set temperatures, load, even simulate sensor disconnection, having the ability of monitoring and registering the resulting EEC control decision. Those activities are realized by an electronic circuit involving 8-bit microcontroller and signals level match elements usage. Currently chosen target to interface with is Ford EEC IV unit, originally designed for Ford Sierra 2.0DOHC EFI engine. A series of successful measurements of ignition angle and cylinder filling characteristics have been done. Achieved results were verified with empirical data collected from a real engine.

It is common knowledge that transmission systems are being pushed ever closer to their stability and thermal limits. Traditional solutions for upgrading electrical transmission system infrastructure have been primarily in the form of new power plants, new transmission lines, substations, and associated equipment. However, as experience has proven, the process of authorizing, locating, and constructing new transmission lines has become extremely difficult, expensive and time-consuming. This is the reason why during the last few years interest in dispersed generation, power flow controlling or/and energy storage has increased significantly – interest in solutions which can improve the efficiency of the distributed power system. With respect to the above the major aim of this paper is to present the fundamental problems of the Power Systems and the improvement methods which arise using Distributed Generation. The paper introduces also a system for the utilization of energy generated on the customerside – this arrangement is realised using a Voltage Active Power Filter. The experimental results presented in the paper confirm the flexibility of this arrangement in efficiency improvement processes.

Experimental and theoretical investigations of the optical and magneto-optical (MO) properties of sputter deposited Fe/SixFe1-x multilayers (MLS) are presented. The diagonal and off-diagonal components of the optical conductivity tensor of the MLS have been determined in the photon energy range 0.8-5.8 eV from the measurements of the magneto-optical complex Kerr angles and the optical data measured by the spectroscopic ellipsometry and compared with the theoretical ones calculated from first principles in density functional theory by the LMTO method within the supercell approach. The calculations have been performed for different models of iron silicide structures. In particular, various spacer layer structures: metallic FeSi and semiconducting FeSi2 iron-silicide phases, as well as pure Si and Fe were investigated. The comparison of the recorded and calculated spectra confirm the conclusion inferred from other studies that the spacer layer structures represent semiconducting A-FeSi and A-FeSi2 phases rather than the metallic FeSi phase.

Tensile tests of 8009Al alloy reinforced with SiC and Al₂O₃ particles fabricated by powder metallurgy (PM) were conducted at temperatures of 250–350°C and strain rates of 0.001–0.1 s⁻¹. The ultimate tensile strength and yield strength of the samples decreased while the temperature and strain rate increased. The elongation slightly decreased at first and then increased with growing temperature because of the medium-temperature brittleness of the alloy matrix. When the strain rate was 0.1 s⁻¹, the elongation of the 8009Al/Al₂O₃ composites always decreased with an increase in temperature because of the poorly coordinated deformation and weak bonding between the matrix and Al₂O₃ particles at such a high strain rate. The work-hardening rates of the composites sharply increased to maxima and then decreased rapidly as the strain increased. Meanwhile, the 8009Al/SiCₚ composites displayed superior UTS, YS, elongation, and work-hardening rates than those of the 8009Al/Al₂O₃ composites under the same conditions. Compared to 8009Al alloys reinforced with spherical Al₂O₃ particle, 8009Al alloys reinforced with irregular SiC particles exhibited a better strengthening effect. The fracture mechanism of the 8009Al/SiCₚ composites was mainly ductile, while that of the 8009Al/Al₂O₃ composites was primarily debonding at the matrix–particle interfaces in a brittle mode.

The effect of interface anisotropy on the electronic structure of InAs/GaSb type-II superlattices is exploited in the design of thin-layer superlattices for mid-IR detection threshold. The design is based on a theoretical envelope function model that incorporates the change of anion and cation species across InAs/GaSb interfaces, in particular, across the preferred InSb interface. The model predicts that a given threshold can be reached for a range of superlattice periods with InAs and GaSb layers as thin as a few monolayers. Although the oscillator strengths are predicted to be larger for thinner period superlattices, the absorption coefficients are comparable because of the compensating effect of larger band widths. However, larger intervalence band separations for thinner-period samples should lead to longer minority electron Auger lifetimes and higher operating temperatures in p-type SLs. In addition, the hole masses for thinner-period samples are on the order the free-electron mass rather than being effectively infinite for the wider period samples. Therefore, holes should also contribute to photoresponse. A number of superlattices with periods ranging from 50.6 to 21.2 Å for the 4 µm detection threshold were grown by molecular beam epitaxy based on the model design. Low temperature photoluminescence and photoresponse spectra confirmed that the superlattice band gaps remained constant at 330 meV although the period changed by the factor of 2.5. Overall, the present study points to the importance of interfaces as a tool in the design and growth of thin superlattices for mid-IR detectors for room temperature operation.
