Authors: Arkhipov A. E. 
Published: December 2023

Purpose of research. Development of a method and algorithm of complex analog radio signals filtering and binarization, such as the signal of Automatic dependent surveillance-broadcast (ADS-B), which allows to increase the sensitivity of the receiver of the AZN-B signal and increase the number of correctly detected received messages.Methods. To solve this problem, the basics of the theory of signal filtering and the theory of fuzzy sets were applied in the work. The proposed method is based on combining signal filtering by known filters and a two-level fuzzy model. The first and second levels of the fuzzy model contain three operations: automatic formation of membership functions, compositional output and defuzzification. Input variables of both levels are given by trapezoidal membership functions. At the first level, they are formed automatically depending on the characteristics of the complex signal. The output function at the first level is given by a singleton function, and defuzzification is carried out using a simplified center of gravity model.Results. The proposed algorithm was implemented in the developed device based on a programmable logic integrated circuit (FPGA). In addition to filtering, the developed device implements all signal processing functions, such as: receiving input data, decoding, checking the correctness of decoded data, storing them, transmitting ADS-B messages for further processing. A distinctive feature of the device is its small size and low power consumption, which allows use it in small spacecraft and unmanned aerial vehicles.Conclusion. A method of filtering complex signals based on a fuzzy logic model is considered, which can be used to filter complex signals, such as ADS-B messages in small spacecraft modules. The proposed implementation of the filtering method makes it possible to increase the sensitivity of the AZN-B signal receiver by 20% and correctly decode the received signal. The method was implemented by an FPGA-based device, which made it possible to reduce the size and power consumption compared to analogues.

Published: December 2023

Resume. The development of the heat pump market ensures the growth of energy prices, the fight against global warming and the stimulation of the growth rates of countries in transition to "clean energy sources". the most environmentally friendly and energy efficient, taking into account the cost of their installation and the impact of air source heat pumps compared to geothermal ones. However, their use in countries with cold climates is limited by the formation of frost on the evaporator unit heat exchanger, which significantly increases their heating capacity and conversion efficiency.Purpose of research. The purpose of this work is to compare the efficiency of heat pumps with an evaporative circuit heat exchanger manufactured by MITSUI (Japan) and a heat exchanger with a MOVEBIT defroster manufactured by ALTEC (Russia).Methods. The research methodology is based on large laboratory tests of an evaporator with an oscillatory circuit of the MOVEBIT system (ALTEK - Russia) and an industrial heat exchanger MITSUI (Japan), a graphical analysis of the operation of a heat pump with common evaporators, and a theoretical substantiation of the transformation ratio. To compare the main standardized performance indicators, the transformation coefficient (COP – coefficient of performance) is used, showing the ratio of received energy to applied work.Results. The analysis of the results of the heat pump operation showed that while maintaining the humidity at a constant level of φ ≈ 65% and lowering the temperature from +10°C to +5°C, a decrease in the heat output of the unit is observed, regardless of the type of MOVEBIT and MITSUI heat exchanger, which is explained by the formation of condensate. With a further decrease in temperature to zero and below, ice forms on the evaporator of the heat exchanger. Taking into account the cost of removing ice on the MITSUI heat exchanger, the transformation ratio of the heat pump unit (HPU) is 2.08. The removal of ice by the MOVEBIT system practically does not require additional costs and the transformation ratio of the installation is 4.45, which is similar to the operation of an air source heat pump at positive temperatures.Conclusion. Our studies show that the best prospect for de-icing is the application of mechanical oscillations with the use of magneto-constrictive transducers. The COP of the air source heat pump with the MOVEBIT system exceeds the COP of the heat pump with the MITSUI standard evaporator by 2 times at a temperature of 0°C and below.

Published: December 2023

Abstract
Moisture damage (Stripping) in Hot Mix Asphalt (HMA) is the loss of adhesive bond between aggregate particles and bitumen due to water action. Most urban roads in Iraq have been exposed to moisture damage failure because of the high silica content in aggregate, this phenomenon led to a decrease in the service life of roads and an increase in maintenance cost. This study used two anti-stripping agents: hydrated lime and Wetfix-BE. Lime was added as a powder to the aggregate in a dosage of 2.0 % of the aggregate weight and Wetfix-BE, a liquid chemical adhesion promoter for hot and warm mix asphalt, was added to asphalt at in dosage of 0.5 % from the total weight of asphalt. The retained Marshall stability, tensile strength ratio, Texas boiling test, and static immersion test are calculated to determine the resistance to moisture damage. The results indicated that both Wetfix-BE and lime could increase Marshall retained stability, tensile strength, and resistance to moisture damage of mixtures, especially at higher condition temperatures. The bitumen modified with Wetfix-BE had better results than bitumen modified with lime for all tests at different temperatures.

Changes in regional settlement systems in Poland
Authors: Runge Anna 
Published: December 2023

Abstract
This article is an attempt to identify regularities in changes in regional settlement systems in Poland with an indication of the elements that showed the highest population dynamics (growth or decline) in particular periods, thus contributing to changes in the structure of these systems. In order to show similarities and differences in the course of the analyzed changes, univariate statistical measures (median, quartiles) were used. This allowed for presenting a dynamic typology of these changes in order to show their cyclical nature and spatial diversity. The results show that these processes do not occur in a similar direction in all regions. The model of consistent changes in the size structure of cities concerns the settlement core of the country (Mazowieckie, Wielkopolskie, Małopolskie), while the resequential changes generally took place in the agricultural peripheries of the country (Podlaskie, Warmińsko-mazurskie), which were drained from the demographic potential by the migration outflow of the population the earliest, as well as in industrial regions (Śląskie, Łódzkie), where the political and economic transformation significantly affected population processes.
