Parallel algorithms for large applied problems: Issues and technologies
Optoelectronics, Instrumentation and Data Processing - Tập 43 - Trang 99-111 - 2007
Topical issues of parallelizing computational methods and technologies for implementing the main mathematical modeling stages in solving a wide range of large applied problems are considered. Computation-information process models, classification of the main types of algorithms, and principles of their efficient mapping onto the distributed-and shared-memory computer architecture are described.
An interrogation technique for fiber Bragg grating sensors based on optical time-domain reflectometry
Optoelectronics, Instrumentation and Data Processing - Tập 44 - Trang 178-182 - 2008
A method for fiber Bragg grating (FBG) interrogation is proposed. The method rests on measuring the light intensity reflected from FBG sensors by means of a standard optical time-domain reflectometer. Multiple FBGs along the fiber optic line are interrogated through time division multiplexing. Specifications of FBGs enabling linear response of the sensors to strain and temperature are determined. ...... hiện toàn bộ
Transport Properties of Two-Dimensional Topological Insulators and Excitonic Condensates
Optoelectronics, Instrumentation and Data Processing - Tập 56 - Trang 545-552 - 2021
The paper reviews studies of the Laboratory of Theoretical Physics of the Rzhanov Institute of Semiconductor Physics, Siberian Branch, Russian Academy of Sciences. Two research directions are discussed: transport properties of two-dimensional excitonic systems and electron transport in two-dimensional topological insulators. Particular attention is given to excitonic systems in the mode of Bose–Ei...... hiện toàn bộ
Spectrophotometric method for measuring the groove depth of calibration reflection gratings
Optoelectronics, Instrumentation and Data Processing - Tập 48 - Trang 211-217 - 2012
A method for measuring the groove depth of calibration gratings is proposed which is based on measuring the spectral dependence of the the zero-order reflection diffraction efficiency. The errors of the method are determined by three main factors: the shift of the maxima of the spectrum due to the wall slope of the grating grooves, the error in setting the wavelength of the spectrophotometer, and ...... hiện toàn bộ
Photodesorption of molecular nitrogen from the glass surface
Optoelectronics, Instrumentation and Data Processing - Tập 49 - Trang 608-614 - 2014
Results of experiments on photodesorption of molecular nitrogen from the glass surface are presented. The study is performed in vacuum glass cells whose internal surface is illuminated by a powerful pulsed lamp. The dynamics of the nitrogen density in the cell due to photodesorption is studied with the use of a mass spectrometer and a vacuum ionization lamp. A qualitative comparison of experimenta...... hiện toàn bộ
Ellipsometric monitoring in label-free microarray biotechnologies
Optoelectronics, Instrumentation and Data Processing - Tập 47 - Trang 472-481 - 2012
The surface of biochips prepared on the basis of silicon wafers for studies of reactions of pre-immobilized oligonucleotides and protein molecules was analyzed by high-resolution scanning ellipsometry. The hybridization interactions of nucleic acid (duplex formation in the reaction of an amplicon of the influenza A virus matrix protein gene with probe molecules), sorption of protein molecules, and...... hiện toàn bộ
Method of binary search for image elements of functionally defined objects using graphics processing units
Optoelectronics, Instrumentation and Data Processing - Tập 50 - Trang 606-612 - 2015
This paper deals with the real-time synthesis of high-quality images, a method of defining free forms without approximating them with polygons or patches, issues of using perturbation functions for real-time animation of the surfaces of three-dimensional objects. A method for visualizing functionally defined objects adapted for graphics processing units is proposed, and methods of transforming the...... hiện toàn bộ
Methods of Spatial-Temporal Processing of Broadband Signals and Approaches to Their Modeling
Optoelectronics, Instrumentation and Data Processing - Tập 58 - Trang 160-166 - 2022
Various methods of adaptive spatial-temporal processing of signals in a survey radar system (RS) using a digital antenna array and broadband probing signals and operating under conditions of intense active and passive interference are considered. Approaches to modeling the interference affecting RSs and algorithms for their suppression in adaptive signal processing are discussed. It is proposed to...... hiện toàn bộ
Adaptive Traffic Signal Control Based on Neural Network Prediction of Weighted Traffic Flow
Optoelectronics, Instrumentation and Data Processing - Tập 58 - Trang 503-513 - 2023
We propose a two-stage method for adaptive traffic signal control based on an estimate of the predicted weighted flow of vehicles passing through an intersection. At the first stage, the time for each vehicle to pass the intersection is estimated using an artificial neural network model; then, the predicted flow of vehicles through the intersection for a given phase of the traffic light cycle is e...... hiện toàn bộ
Identification of the Dynamics of a Moving Object with the Use of Neural Networks
Optoelectronics, Instrumentation and Data Processing - Tập 54 - Trang 617-622 - 2019
A method for identification of the dynamics of a quadrotor-type vehicle is proposed. The method is based on the Elman recurrent neural network, which corresponds to the canonical form of a dynamic system in the space of states and does not require structural correction. The results of a numerical experiment reveal the convergence of the network learning algorithm with the use of an extended Kalman...... hiện toàn bộ
