This paper presents the new face verification algorithm based on deep convolutional neural network. The algorithm produces face feature vectors, distance between these vectors allows to determine whether images from the same class. Comparative experimental results are given for LFW test database and modern face recognition algorithms. ROC-curve and equal error rate are used to determine the accuracy...
In paper, the technique of generation of all possible structures of digital filters with the fixed number of nodes is offered. As a mathematical model of the structure of the digital filter, a topological matrix of the transmission coefficients between the nodes of the structural scheme was used. Templates have been built for the formation of specific structural schemes. Structural units of block...

The problem of ensuring the safety of passengers waiting for public passenger transport at a halting point is considered. In addition, due to the large number of vehicles in the streets and road networks of cities, the lack of parking spaces, there is a problem of parking at bus stops. In order to solve the above problems, it is suggested to equip a bus stop with the necessary equipment for admission...
A new approach to partially programmable combinational circuit design that allows masking single stuck-at faults of wires is considered. It is supposed that only one wire may be fault. The combinational circuit consists of gates, look-up tables (LUTs) and Multiplexers (MUXs). The approach is based on using incompletely specified Boolean functions for finding sub-circuits from gates that may be covered...
The problems of IC reliability are now becoming increasingly important. The idea of reliability is a complex integrated concept and includes structural, schematic and technological solutions, as well as solutions at the level of logic gates, register transmissions and microsystem as a whole. This paper is devoted to preprocessing of logical circuits aimed at the reduction of computational costs of...
The article describes implementation issues of jet-acoustic sensors for building high-speed temperature measuring devices of gas. The brief overview of the existing methods of measurement of high temperatures and their advantages and disadvantages has been examined. The use of fluidics elements here for initiating the oscillations in the acoustic generator has been justified. Solutions of problems...
The paper presents a Finite State Machine (FSM) based approach for deriving tests with reduced complexity, under the White Box testing assumption where all the faulty implementations are explicitly enumerated. The specification and implementation FSMs are assumed to be initialized, i.e., each possibly partial and (non-observable) nondeterministic FSM has a reliable reset. The proposed technique is...

The proposed method is based on the calculation of the load of the central processor, memory and bandwidth fractal information streams of different classes of service for each server and the entire distributed system. The method allows calculating the imbalance of all...
With the increasing technological complexity modern SoC designs continue to grow in size and involve increasingly more IPs. Therefore, it becomes much harder to complete testing of large SoCs within the desired schedule and cost. Usually an automated hierarchical test helps to solve this problem efficiently but for such systems the preparation of input data, especially IP level information and description...
This paper is devoted to a problem of on-line testing efficiency in digital components of safety-related systems taking into account their design for operation in two modes: normal and emergency. Approach to increase of on-line testing method trustworthiness in checking of approximate results is offered. Approach is based on distinguishing of the essential and inessential errors caused by faults of...
The market share of portable and loT (Internet of Things) devices has been rapidly growing over the last decade. In parallel the amount of non-volatile memories, especially flash memories, used in such devices has also increased significantly due to their low power consumption and capability of in-field programmability. Therefore, for achieving high production yield the reliability and testability...
This paper describes the first steps towards a union of low-cost “Shrinky Dink” (SD) microfluidic chip fabrication with low-cost do-it-yourself (DIY) micro-PIV. The SD microfluidic chip fabrication technique enables rapid development of complex designs using inexpensive materials and reagents, while abrogating the need for a cleanroom. DIY microPIV system provides a low-cost means of accurate flow...
This work proposes a fault diagnosis methodology intended for resistive memories. Multiple cells of a block may suffer from stuck-at faults during repetitive write operations in resistive memory. It causes serious hindrance to large scale adoption of resistive memory. This issue is addressed through introduction of von Neumann's Cellular Automata (CA). The two single length cycle attractor CA (TACA)...
