Computer simulation of thin film growth and annealing processes on early stage at atomic and molecular level is one of the most important stages to study and increase high quality of obtained thin films or coatings. And in this paper, the computer simulation will be presented at different conditions to show which influence facts and their contribution on the quality of obtained films based on built models and algorithms. Basic numerical methods used in this work is a combination of two methods based on the specifics of thin film growth, in the random and self organization processes, we use Monte-Carlo method with a choice of number of particles and quasi-Newton method with the definition of the direction of particle's motion. Based on the kind of on-going process and deposition (or sputtering) materials, various sub models are built.

Theoretical and experimental research of total ionizing dose (TID) effects on high voltage (HV) MOS transistor I-V characteristics are presented. MOS transistors, manufactured in 2 different Bipolar-CMOS-DMOS (BCD) technological processes, were used in the research. HV MOS are used for power management ICs undergoing harsh radiation. Thus, devices underwent radiation to various TID levels up to 105 krad. The obtained results allowed to modify the SPICE models of transistors taking into account the changes of their characteristics. As the result, it will be possible to evaluate the effects of TID on power management IC's functional characteristics and increase their reliability in future. The results of the study show that BCD 0,5 um has better radiation resistance than BCD 1 um, but breakdown voltage of BCD 1 um is higher than that of BCD 0,5 um.

In the report there is the review conducted with the subsequent selection of the method from the current processing algorithms with further analysis of revealing their advantages over the other signal processing methods. As well as there is an example of the implementation of a ground penetrating radar, that is a promising direction in this field. The research into the differences between using narrow-band signal and UWB allows us to understand during the implementation of the UWB radar, when we can use the traditional theory of radar detection, and when it is necessary to look for new methods.

The Internet of things brings to life a new set of services that can be deployed on the mobile network operator and offered to the end user, for example, services such as: tactile Internet, augmented reality, virtual reality, medical networks, weather forecasting, smart homes and smart cities, completely automated cities with smart self-learning algorithms for managing everything. This paper considers the possibility of implementing services of the “Smart City” concept. Based on the experience of other cities, we can conclude that the most interesting and popular will be the implementation of intelligent street lighting, that allows the municipality to save budget funds, spent on street lighting in the city. For implementing this service, using a standardized wireless technology for building a physical network and a unified service model, in future it will be possible with minimal investment to increase the number of services, adding, for example, air pollution analysis, or “smart” waste containers. In this paper we analyze wireless technologies with low power consumption and long range. Based on the analysis was chosen the best technology, which can be used in smart city to provide a “smart street lighting” service. In results model for providing “smart street lighting” service was developed, which includes equipment, the scheme of the overall network organization, as well as its logical implementation in a unified service model, and also in this work we tested the network segment built using the selected wireless technology LoRa.

This paper describes models and algorithms for intelligent control of a group of autonomous mobile robots, which perform large-sized object transportation in a complex environment. The proposed models allow the multi-robot system to reach its target position while avoiding obstacles and maintaining object orientation with coordinated motion of several robots. We use neural based Q-learning to provide robots adaptability to unknown environments. The inputs of the learning subsystem are 2d-map data collected during system operation and target misalignments of multi-robot system. The primary output is a control decision with a maximum value of estimated efficiency. Experimental results presented in the paper fully confirm the reliability of the proposed approach.

This paper covers non-conventional recurrent data-flow architecture, its features, and implementation aspects. Recurrence — the main feature of the new architecture efficiently solves data redundancy problem, typical for data-flow architectures while increasing performance. Conventional recurrence implementation has an overhead of configuration operand insertion that provides required functional fields (tags). Functional capabilities expansion of the architecture mechanism implementing this feature resulted in further efficiency by eliminating said overhead in some instances. We cover enhancements implemented in multicore recurrent data-flow architecture, designed to increase the versatility of recurrent computational process utilization. We compare Viterbi algorithm implementations with and without enhancements.

Analog-to-digital converters (ADC) are used in modern high-performance telecommunication systems. The fastest ADC is based on the flash architecture. The flash ADC speed is limited by two factors. The first one is the comparator response time in the input analog part of ADC. The second factor is the delay time of the encoder. The encoder converts the thermometer code into the straight binary code. In this paper, design of encoder circuits based on CMOS technology is considered. New encoder circuits with reduced delay are proposed. Comparative analysis of encoder main characteristics based on the circuit simulation is presented.

The paper presents an algorithm to determine the location of two-channel gateways in two-level network to reduce response time of second-level network. To evaluate response time in second-level network with bus topology an integer functions are proposed. The algorithm is based on construction of approximation function by three special points or using the least squares method. It's shown for tree topology that construction of approximation function using three special points must be preceded by finding the numeration order of tree edges such that all edges corresponding to optimal values of the integer functions have adjacent numbers. The paper shows that in order to numerate edges in such a way a special condition based on the Hamiltonian cycle must be satisfied. If the condition is not hold the paper propose sequential procedure consisting of several steps of edges renumbering and local optimal values of approximation functions subset determination.

This paper presents results of in vitro and in vivo trials of a wearable artificial kidney (WAK) based on peritoneal dialysis. Materials and methods: in vitro trials were carried out in a developed test bench, which imitates patient's peritoneal cavity and capable to measure main procedure parameters. In vivo trial was carried out on a 15 kg dog in a healthy state to evaluate the effect of WAK on blood biochemical indicators and in an acute kidney injury state to test WAK's blood purification capabilities. Results: in vitro trials demonstrated that WAK could eliminate urea, uric acid and creatinine from spent dialysate with mean mass rates of 0.85±0.1 g/h, 0.10±0.04 g/h and 0.05±0.01 g/h respectively. Concentrations of Na+, Cl− and Ca2+ ions are kept in 10 % range from initial values. It is demonstrated that WAK can operate without replacement of expendable materials for 38 hours. During in vivo trial (39,5 hours), WAK performed continuous peritoneal dialysis with dialysis fluid regeneration. In acute kidney injury conditions (34 hours) creatinine and uric acid were eliminated from dialysing solution with the rate of 0,3 mg/h, urea was eliminated at the rate of 0,15 g/h, total removed ultrafiltrate volume was 350 ml. At the end of the second stage blood biochemical indicators stabilised in the range of normal values. Conclusion: developed WAK can perform elimination of metabolites from spent dialysis fluid with mass rates that are sufficient to maintain stable, physiologically normal metabolite concentrations in patient's blood.
