Item Express method of threshold voltage control of dmos transistors in the process of their manufacturing(Видавництво Львівської політехніки, 2012) Politansky, Leonid; Lesinsky, ValentinThere is shown the use of test structure for DMOSstructure threshold voltage control and correction.Item Methods for controlling levels of electromagnetic radiation in indoor spaces(Видавництво Львівської політехніки, 2012) Serkov, Oleksandr; Tolkachov, MaksymWe propose a model of a system for control of resistance levels of electronic systems with regard to electromagnetic noise in indoor spaces, which allows analyzing cumulative averages of electromagnetic fields of concentrated sets of radiation sources.Item Simulation approaches of low-dimension structures for biosensing(Видавництво Львівської політехніки, 2012) Bodilovska, DariaModeling theory and simulation approaches of field effect transistor (FET)-based sensor for biomolecules detection are presented.Item Computer simulation of the impact of the magnitude of applied field and surface anchoring force on gradient lightguide formation in the layer of nematic liquid crystal(Видавництво Львівської політехніки, 2012) Ilnytskyi, Jaroslav; Fechan, Andrij; Sushynskyy, Orest; Tomashevskyy, Oleh; Kotsun, Volodymyr; Varanytsia, Andrij; Adamchuk, OlenaThere were investigated phase diagram and distribution profile of the director field of simulated liquid crystal which is kept in the pore with homeotropic boundary conditions in different phases. By the means of molecular dynamics method there was performed the computer simulation of the changes of refractive index profile in gradient lightguide under the surface anchoring force and applied electric field.Item On the mathematical approaches to multi-state PAL models for porous solids(Видавництво Львівської політехніки, 2012) Klym, HalynaThe mathematical approaches for all positron annihilation processes in porous solids for electronics are performed within multi-channel model, which include positron trapping modes and positronium decaying.Item High-voltage power supply based on piezoelectric transformer(Видавництво Львівської політехніки, 2012) Kryvoshei, Dmytro; Paerand, YuriyHigh-voltage power supply based on piezoelectric transformer instead of traditional electromagnetic transformer is offered in the paper. The structure of the power supply is represented. The power supply operation principle is described, the diagrams that illustrate its operation are given.Item Self-oscillations in recurrent neural structures(Видавництво Львівської політехніки, 2012) Romanyshyn, Yuriy; Petrytska, SvitlanaIn this paper the conditions of the selfoscillations in one and two neurons with feedback are considered.Item Modeling of the air duct is for the selective serve of air to the radio electronic blocks(Видавництво Львівської політехніки, 2012) Fast, Volodymyr; Yangursky, Kostyantyn; Atamanova, IrynaMathematic modeling is applied to identify the specificity of designing an air duct of constant cross-section with apertures different in area.Item Mathematical model of channel current in FET-based nanobiosensors(Видавництво Львівської політехніки, 2012) Bodilovska, Daria; Popov, AntonField effect transistor (FET)-based sensor for biomolecules detection has been simulated.Item Influence the bonding jumpers characteristics on the microstrip coupler lange parameters(Видавництво Львівської політехніки, 2012) Furmanova, NataliyaIn the paper effect of the bonding jumpers characteristics as the shape, diameter, material and the number of jumpers on the microstrip coupler Lange parameters was investigated.
