A deterministic-statistical model for the analysis of signal propagation indoor is proposed. The model is based on a combination of the deterministic three-dimensional ray tracing method and the statistical account of the changing spatial structure of the communication channels and the irregularities of the reflecting surfaces. The channel matrix elements of the MIMO system are estimated based on the proposed model.

In this work compact branch-line coupler with the use of microstrip U -shaped containers with different thicknesses of the substrate used are developed. With the help of a specialized program, an assessment was made of how much the change in such a substrate parameter as the thickness of the possibility of miniaturization affects coupler. Miniaturization of the area of devices was realized due to reduction of dimensions with the help of equivalent circuits in the form of a high-resistance line and connected to it in parallel with U-shaped capacitance. The characteristics of this circuit have similar characteristics in the frequency band with the characteristics of the segments used in the standard scheme. Let's consider three variants of designs of power dividers with different substrate thicknesses from 1 to 2 mm, with a step of half a millimeter. Proceeding from this, it was found that when the thickness of the substrate is reduced, the possibilities to reduce the dimensions of the device are increased.

This article describes the first steps in the development of a low-cost digital sensory glove that designed for use in virtual reality systems especially. Existing concepts of gloves differ in features and design, they have various functions, including feedback, tactile feedback to the electric discharge, a feeling of finger bending, finger grip strength and prediction of action and three-dimensional spatial positioning - to improve sensation and practical experience in virtual reality. Manual dynamic perception and freedom of action, common in the real world, provide instant information about objects in the virtual world. Digital gloves act not only as a remote control in VR, but also provide physical feedback for the user when they come in contact with virtual objects. This article presented an own design for inexpensive gloves that allow for proximal and distal finger joint movements, as well as position/orientation determination with an inertial measuring unit. These sensors and tactile feedback caused by the vibration patterns of the coins at the fingertips are integrated into a wireless, easy-to-use and open-source system. The design of hardware, as well as experiment plans for proof of concept, is presented.

The article gives an analysis of the advantages and disadvantages of the original method for implementing a practical spectrum analyzer based on the discrete Fourier transform (DFT). There are two names used for this method: the weighted overlap-add structure, and the window-presum FFT method. It is shown that the main disadvantage of the weighted superimposition-addition method is the fixation of the central frequencies of the filters of the realized spectrum analyzer. The theoretical foundations of this method have been discovered and investigated. It is shown that the reason for the disadvantage of the method is the procedure used for preliminary data processing in the time domain. Based on the analysis of the DFT matrix, it is shown that the preprocessing procedure used in the time domain is only one of the possible procedures. A generalization of the weighted superposition-addition (FFT method with preliminary summation) is proposed on the basis of a parametric discrete Fourier transform.

Scan-based Design-for-Test (DfT) feature aims to fulfil the need for better testability and diagnosability of a modern-day VLSI chip. However, an unprotected scan architecture can be exploited by an unauthorized user to steal sensitive data such as a secret encryption key which is embedded on a cryptographic chip. In this work, a new technique is proposed to secure the scan architecture through test authorization mechanism. The proposed technique locks down the scan infrastructure whenever the circuit enters into the test mode of operation. The user needs to pass a test authorization step in order to unlock the scan feature and exercise the scan test. The test authorization step is a one time process which must be passed at the start of the test session. The proposed secure scan test technique has no overhead in terms of test time and test data volume. Furthermore, the proposed secure scan design has marginal area overhead and has similar debug capabilities as the conventional scan design.

The robustness of standard CMOS combinational logic gates to Single Event Transients (SETs), in the presence of resistive open and resistive bridge defects, was investigated. Analysis was performed with SPICE simulations, using the resistors for modeling the open and bridge defects, and a standard double-exponential current source for modeling the SET effects. Two simple circuits based on NAND gate, designed in IHP's 130 nm bulk CMOS process, were employed for this study. It was demonstrated that, for certain input logic levels, the intra- and inter-gate resistive open and bridge defects may lead to significant decrease of the gate's critical charge, and thus to the increase of its soft error rate (SER) by more than one order of magnitude. Also, it was shown that the SET pulse width may significantly increase due to the resistive defects. Simulation results have confirmed that the resistive open defects have a stronger impact on the SET robustness of standard logic gates than the resistive bridge defects.

A method for increasing the slew-rate (SRHS) in the invert connection of an operational amplifier (OA) with a dual-input-stage is proposed. The principle of the method includes introduction of two nonlinear differentiating correction circuits (DCc) of the transient into the classical OA circuit which form additional overcharge currents of the integrating capacitance of the OA correction in the high-signal operation. At the same time, the DCcs practically don't affect the small-signal response of the OA. The OA circuits of the proposed subclass can have a low consumption current in the steady-state behavior and be performed on the basis of typical technological processes (CMOS, BiJFet, BJT, SiGe, etc.). The results of computer modeling of BJT OA on integrated transistors of JSC “SPE Pulsar” (Moscow) show that the SRHS of the inverting OA, with ideal current mirrors and the buffer amplifier, increases more than 15 times (to 20,000 V/µs).

The article proposes an algorithm for modeling of the process monomers copolymerization, which is carried out in a continuous mode in a cascade of consistently connected reactors of ideal mixing. The algorithm is based on the Monte-Carlo method. It is based on the imitation of growth of each macromolecule of the formed copolymer and fixation of the processes occurring with it. Since the process is conducted in a continuous mode, the algorithm takes into account the distribution of product particles according to the time spent in the system, as well as the constant flow of reaction mixture into the first cascade reactor. The model built on the basis of the algorithm allows to estimate indicators of the product at any time, namely: to predict molecular-mass and viscosity characteristics, mass content of the original monomers in the copolymer, to carry out calculation of molecular-mass distribution, to investigate composite heterogeneity of a product. The proposed algorithm can be implemented as a software tool, in this connection the article proposes an approach to the storage and processing of used data. According to the results of the research a number of computational experiments on modelling of production of butadiene-slipper synthetic rubber in industrial conditions were carried out. The basis of its production is the process of low copolymerization of butadiene with styrene in emulsion. The simulated results reflect consistency with the experimental data.

The design and operation of an autodyne proximity sensor is considered. The autodyne system generator is constructed using a microstrip antenna as an open oscillation system of the device. At two points, the microstrip antenna is connected to the source and the source of the field-effect transistor. The central part of the microstrip antenna is connected to the common wire. The connection of the transistor and microstrip antenna is equivalent to the Hartley generator system (inductive three-point). In the drain circuit of the FET, the useful signal of the motion sensor is picked up. The motion sensor has a certain ease of implementation, while it allows registering moving objects at a distance of several tens of meters.
