Computational Methods in Science and Technology
EN A combined molecular dynamics and molecular mechanics method has been developed for estimating Poisson's ratios of certain types of molecular auxetics at various temperatures. The tem­perature dependence of the auxeticity of a special class of molecular auxetics, namely, a self-expanding supramolecu[...]

EN We present a framework for the identification and processing of scan sheets by using an array model. Certain submatrices of the arrays representing scan sheets contain the designated information for processing. Based on certain algebraic operations on arrays, eective techniques are formulated for pr[...]

EN This paper presents a new set of bivariate discrete orthogonal moments which are based on bivariate Hahn polynomials with non-separable basis. The polynomials are scaled to ensure numerical stability. Their computational aspects are discussed in detail. The principle of parameter selection is establ[...]

EN In this paper, the gamma - gamma probability distribution is used to model turbulent channels. The bit error rate (BER) performance of free space optical (FSO) communication systems employing on-off keying (OOK) or subcarrier binary phase-shift keying (BPSK) modulation format is derived. A tip-tilt [...]

PL Kluczem do algorytmu pozycjonowania wykorzystującego metodę fingerprinting jest ustanowienie skutecznej bazy danych na podstawie informacji z radiowych nadajników referencyjnych przy wykorzystaniu wskaźnika mocy odbieranego sygnału (RSSI). Tradycyjna metoda oparta jest na przeprowadzeniu kalibracji [...]
EN The key to fingerprint positioning algorithm is establishing effective fingerprint information database based on different reference nodes of received signal strength indicator (RSSI). Traditional method is to set the location area calibration multiple information sampling points, and collection of [...]

EN The objective of the research documented herein was to investigate high-accuracy identification and measurement of a work-piece through edge detection, and to derive its three-dimensional properties from a profile of the work-piece image. A number of techniques for providing the transformation of th[...]

EN The phenomenon of core disking is commonly seen in deep drilling of highly stressed regions in the Earth’s crust. Given its close relationship with the in situ stress state, the presence and features of core disking can be used to interpret the stresses when traditional in situ stress measuring tech[...]

EN To model and analyze systems with multi-valued information, in this paper, we present an extension of Kripke structures in the framework of complete residuted lattices, which we will refer to as lattice-valued Kripke structures (LKSs). We then show how the traditional trace containment and equivalen[...]

PL W artykule przedstawiono metodę optymalizacji rozmieszczenia i gęstości odwiertów oraz zbalansowania ilości studzien poziomych, co zapobiegnie nierównomiernym rozpływom cieczy. Dodatkowo pozwoli to na kontrolę ciśnienia przy wytwarzaniu poziomych sekcji oraz jednorodne przedłużanie profilu przepływu[...]
EN The horizontal wellbore pressure and reservoir heterogeneity are major factors in the horizontal well uneven inflow. Given the situation, it is to establish balanced production of horizontal wells as the objective function, and holes dense as the optimization which is a typical constrained nonlinear[...]

EN Currently there are more and more ships sailing in inland waterways so that the traditional inland shipping management information system (ISMIS) becomes relatively backward. Based on the rapidly developed new information technologies, such as wireless sensor network, Internet-of-things, cloud-compu[...]

Opto - Electronics Review
EN An all-fibre multi-parameter sensor for composite structures based on a chirped optical fibre Bragg grating (CFBG) has been studied theoretically and experimentally. The principle of multi-parameters sensing with a single CFBG is based on that the centre wavelength and the FWHM (full width at half m[...]

EN In this study, a polarization selective beam splitter constructed by only a single layer subwavelength multisubpart profile grating is presented. Rigorous coupled-wave analysis is adopted to investigate the properties of the structure. It is shown that for a transverse electric polarized wave, the d[...]

EN Nanostructured spherical spinel lithium manganate with about 30 nm in diameter was synthesized for the first time by explosive method. The water-solubility explosive was prepared using a simple facility at room temperature. The growth of lithium manganate via detonation reaction was investigated wit[...]

EN Beam blocked and truncated by the receiver causes serious power losses in beam uplink propagation in a relay mirror system. We propose a method to improve power efficiency of beam uplink propagation in the relay mirror system by using vortex source and phase optimization. A typical model of beam upl[...]
