E-mode AlGaN/GaN HEMTs are generally promising candidate for switching power transistors due to their high breakdown voltage, high current density and low on-resistance. The threshold voltage (Vth) of normally-off mode AlGaN/GaN HEMTs with a self-aligned p-type GaN gate can be successfully improved by...

Inventory control algorithm for the model of a warehouse with time delays is proposed. Inventory control algorithm based on optimization linear and quadratic criteria with using the Kalman filtering for systems with unknown input and smoothing procedures is constructed. Example to illustrate the proposed...

this paper considers a method for solving Cauchy problem of nonlinear differential equation. Source of solution error and way to reduce it is studied. Solution obtained with suggested method is compared with solution obtained with built-in MATLAB functions.

Cognitive and simulation modeling is applied to research the behavior of critically important objects. The fuzzy cognitive model of the organizational-control structure of the object under study is proposed. A computer experiment is carried out, the development scenarios of the object are modeled under...

The use of discrete modeling and the mathematical model of joint deformation to calculate the stress-strain state of the structure is considered in the work. The authors cite the model of joint deformation and the procedure for constructing a discrete model. As an example, the calculation of the stress-strain...

The main principles of photon quantum mechanics describing its one-particle states with the help of the wave function in coordinate representations are given. This wave function (packet) is the superposition of the basic bivectors that are generalized eigenfunctions of energy, momentum, and helicity...

The article presents a semantic model and a technique for application in the development of software and based on synthesis of open information systems a program code generator needs to comply with the following requirements: extensibility, scalability, cross-platform and interoperability. A fragment...

The paper deals with the distributed systems with channel aggregation. The aim of the work is to investigate the possibilities of increasing the efficiency of the exchange through the aggregated channels while making the redundant transmissions of the packet copies that are critical to the timing of...

This article deals with the model of tutoring accompanying students with special educational needs and disability in conditions of professional education. The goals, tasks, main components and specific features of the tutor's activities are presented.

The paper presents the results of physical modeling of the wind pressure. Systematic data are obtained for the pressure coefficient distribution over the sides of the different-size building models under the airflow conditions. These conditions are provided by an obstacle situated in front of the building...

In the article, the convolution of the test results of drivers of motor vehicles on the auto-simulator and on the complex of psychological tests "effecton" is considered.

Stochastic differential equations (further referred to as SDEs) and the models based on SDE are widely used to describe stochastic processes in virtually any area of human activity, such as biology or finance. Unlike an analytical approach to solving SDE, the simulation methods allow to significantly...

This article describes the different aspects of a systematic and a structural-level approach that is considered as the methodological basis for personal-oriented psychological research. The general provisions of the system theory was given, and the following approaches were described: systematic approach...
