    Opis:
    Soil salinity is one of the major impact factors on agriculture in the South of Kazakhstan. Prediction and estimation of soil salinity before planting a season usually helps to plan for the leaching of the salt. In the paper, satellite data such as radar data and machine learning algorithms, were used to classify soil salinity. Numerical results were presented for the Turkestan region, which contains more than 102 points. The machine learning algorithms, including Gaussian Process, Decision Tree, and Random Forest, were compared. The evaluation of the model score was realized by using metrics, such as accuracy, Recall, and f1. In addition, the influence of the dataset features on the classification was investigated using machine learning algorithms. The research results showed that the Gaussian Process model has the best score among considered algorithms. In addition, the results are consistent with the outcome of the Shapley Additive exPlanations (SHAP) framework.

    Opis:
    The paper considers developed and offered an effective algorithm for solving the block-symmetrical tasks of polynomial computational complexity of data processing modular block-schemes designing. Currently, there are a large number of technologies and tools that allow you to create information systems of any class and purpose. To solve the problems of designing effective information systems, various models and methods are used, in particular, mathematical discrete programming methods. At the same time, it is known that such tasks have exponential computational complexity and can not always be used to solve practical problems. In this regard, there is a need to develop models and methods of the new class, which provide the solution of applied problems of discrete programming, aimed at solving problems of large dimensions. The work has developed and proposed block-symmetric models and methods as a new class of discrete programming problems that allow us to set and solve applied problems from various spheres of human activity. The issues of using the developed models are considered. and methods for computer-aided design of information systems (IS).

    Opis:
    At present there exist a lot of technical devices, the failure of which can be connected not only with huge financial losses, but with the treat to the environment as well. Therefore, an important problem is the effective devices conditions diagnostics, including electronic components and check of their operation. Timely faults detecting allows introducing the prevention measures and avoiding serious consequences. Fiber-optic sensors have several advantages, more important of which include the immunity to electromagnetic disturbances, little weight and possibility to be included into the structure being measured. The most perspective are the sensors based on the Bragg fiber gratings. Bragg fiber gratings have several advantages, for instance, they allow creating the distributed measuring massifs, which contain several sensors. As well, they are insensitive to the optic power source vibrations. Variety of using the fiber sensors based on the Bragg fiber gratings has led to producing the Bragg fiber gratings with different spectral characteristics. Homogeneous Bragg fiber gratings have the spectra with solid side lobes, which can influence at the temperature sensor processing characteristics. To level the side lobes there is applied the apodization method, which is one of the means to affect the spectral form. The article herein considers the issues of the Bragg fiber gratings mathematical and computer modeling using the transfer matrix method. Transfer matrix method allows defining the optical components spectral characteristics based on the bound modes theory and description of electromagnetic wave, passing through an optic fiber. In the article there have been analyzed the Bragg fiber gratings in compliance with spectral features, such as transmission and reflectance spectra. As well, there has been carried out the experiment with influence of various parameters at the Bragg fiber gratings spectral characteristics. There have been studied the Bragg fiber gratings spectral features and selected the grating optimal parameters for designing the fiber-optic sensors based on the Bragg fiber gratings.
    Obecnie istnieje wiele urządzeń technicznych, których awarię można powiązać nie tylko z ogromnymi stratami finansowymi, ale także z troską o środowisko. Dlatego ważnym problemem jest skuteczna diagnostyka warunków pracy urządzeń, w tym elementów elektronicznych i kontrola ich działania. Wykrywanie błędów w odpowiednim czasie umożliwia wprowadzenie środków zapobiegawczych i uniknięcie poważnych konsekwencji. Czujniki światłowodowe mają kilka zalet, z których ważniejsze to odporność na zakłócenia elektromagnetyczne, niewielka waga i możliwość włączenia do mierzonej struktury. Najbardziej perspektywiczne są czujniki oparte na siatkach Bragga (FBG). Optyczne siatki Bragga mają kilka zalet, na przykład umożliwiają tworzenie rozproszonych układów pomiarowych, które zawierają kilka czujników. Są również niewrażliwe na wibracje źródła zasilania optycznego. Różnorodność wykorzystania czujników światłowodowych opartych na siatkach Bragga doprowadziła do wytworzenia siatek Bragga o różnych charakterystykach spektralnych. Jednorodne, optyczne siatki Bragga mają widma z pełnymi płatkami bocznymi, które mogą wpływać na charakterystykę przetwarzania czujnika temperatury. Aby wyrównać płatki boczne, stosuje się metodę apodyzacji, która jest jednym ze sposobów wpływania na formę widmową. W niniejszym artykule omówiono zagadnienia światłowodowych siatek Bragga, modelowania matematycznego i komputerowego z wykorzystaniem metody macierzy transferu. Metoda macierzy transferu pozwala na określenie charakterystyki widmowej składników optycznych w oparciu o teorię modów wiązanych i opis fali elektromagnetycznej, przechodzącej przez światłowód. W artykule przeanalizowano siatki Bragga zgodnie z cechami widmowymi, takimi jak widma transmisji i odbicia. Przeprowadzono również eksperyment z wpływem różnych parametrów na charakterystyki widmowe siatek Bragga. Zbadano cechy widmowe siatek Bragga i wybrano optymalne parametry siatki do projektowania czujników światłowodowych opartych na siatkach Bragga.

    Opis:
    In the present work, an exergy analysis was done of two-circuit flat solar collector with thermosiphon circulation. The article presents a mathematical model of energy and exergic analysis of flat solar collectors, as well as calculations of solar radiation efficiency, temperature, flow rate of the fluid, exergy rates and exergy loss rates are done. The significance of the results achieved is high, since experimental studies can detect inefficient components of the solar heating system. The exergetic efficiency of a dual-circuit flat solar collector with a thermosiphon circulation describes irreversibility of the process according to thermodynamic parameters. This is caused by a large the degree of overheating achieved at the end of the processes of compression and evaporation, which leads to large differences in heat exchange temperature based on the heat pump cycle. The exergy efficiency value for the entire system is 70. Maximum values energy efficiency and exergy at noon, 32.5% and 2.23%, respectively. The efficiency of exergy is 4%, and the highest the loss of exergy is the difference between the absorber plates and the sun, accounting for 52.86% of the total exergy rate.
    W niniejszej pracy wykonano analizę egzergetyczną płaskiego kolektora słonecznego dwuobwodowego z cyrkulacją termosyfonową. W artykule przedstawiono model matematyczny analizy energetycznej i egzergetycznej płaskich kolektorów słonecznych, a także obliczono sprawność promieniowania słonecznego, temperaturę, natężenie przepływu cieczy, wskaźniki egzergii i wskaźniki strat egzergetycznych. Znaczenie osiągniętych wyników jest duże, ponieważ badania eksperymentalne mogą wykryć nieefektywne elementy systemu ogrzewania energią słoneczną. Egzergetyczna sprawność dwuobwodowego płaskiego kolektora słonecznego z obiegiem termosyfonowym opisuje nieodwracalność procesu według parametrów termodynamicznych. Jest to spowodowane dużym stopniem przegrzania osiąganym pod koniec procesów sprężania i odparowywania, co prowadzi do dużych różnic w wymianie ciepła w oparciu o cykl pompy ciepła. Efektywność energetyczna całego systemu wynosi 70. Maksymalne wartości sprawności energetycznej i egzergii w południe, odpowiednio 32,5% i 2,23%. Efektywność egzergii wynosi 4%, a największą stratą egzergii jest różnica pomiędzy płytami absorbera a słońcem, stanowiąca 52,86% całkowitego wskaźnika egzergii.

    The paper presents the schemes of various equipment for the mechanical treatment of the industrial and domestic wastewater, which allows removing it from the main part of the pollution. An examination of the shortcomings of the known equipment with the aim of its improvement was conducted. As a result, an installation scheme for continuous high-performance mechanical wastewater treatment was proposed. In contrast to the known equipment, the proposed installation provides a three-staged treatment of wastewater with the help of the two pairs of gratings – for preliminary treatment (removal of large-size pollutions) and by filtration through the two metallic sieves – for normal and fine treatment (removal of small-size mechanical pollutions). The installation consists of highly-efficient appliances for the cleaning of filtering elements in the course of realization of the working process, which provides stable high productivity of treatment. The installation has simple reliable design and low energy expenses. The paper contains the formulas for determining of main operational parameters of the installation: the change of the cross-sectional area of the filtering elements and productivity of the working process, periodicity of cleaning of gratings and sieves, the necessary electric power of installations drives. These formulas can be a basis for further research of installation and for elaboration of a method of its design calculation.

    Opis:
    With the development of information technology, electromagnetic radiation becomes a tangible view of the physical (wave) environmental pollution. Modern scientific research aimed at the components of the elec tromagnetic environment pollution problems mainly involves the anthropocentric approach. There is no procedure for determining the influence of harmful physical factors on biota, in particular in terms of water (Daphnia magna Straus) and air (Drosophila melanogaster L.) environments. A clear system of rationing of maximum permissible levels of electromagnetic radiation, including volume and ecosystems protected areas has not been developed. The article considers the relevant scientific and practical problem of creating a framework for assessing and predicting the negative impact of electromagnetic radiation on the biota related to ethological changes and teratogenesis. The characteristic of all the constituent elements of the system determines the degree of the negative impact of the induction of the magnetic field on the biota: activity, mortality; reproduction; availability, and frequency of Teratology. A method for determining the activity levels of Daphnia and Drosophila total average activity biota was developed and described. The trajectory patterns of Daphnia motion at low activity in the state of stability, with increased activity in the excited state, were created. The results of the research on the negative impact of electromagnetic radiation of industrial frequency on biota were presented. The critical levels of the magnetic field and noise pollution, which cause the depletion and destruction of the test object, the relationship between ethological changes and the occurrence of mutations depending on radiation levels were determined. The biological test objects were proven to minimize the error of the results of determination of electromagnetic effects on the biota, in comparison with the mathematical methods of research.

    Opis:
    This paper presents a time-saving method for monitoring the ecology of a dispersed territory using the delivery of measurement units provided by unmanned aerial vehicles with measurement sensors according to a reverse priority algorithm. It is achievable because of the decreasing mean waiting time of the order inside a queue during low-priority order servicing. The experimental research that confirms the efficiency of the proposed method in the case of delivery distributed measurement systems for low-priority measurement is carried out. The experimental research of the proposed method in the case of one-channel and many-channel SMD that can have an option of order rejection or an in-queue waiting option is conducted in WeBots. The probability distributions in the case of this system applying are compared with similar probability distributions in the case of systems of direct priority applying. Comparison and analysis enable us to conclude that the probability distribution in the case of SMD with a direct priority of delivery tends to decrease and approximates zero. This is related to the fact that means at the end of the queue to be handled have a lower priority, as these means of measurement take longer to handle the order than those at the head of the queue. Thus, the means of a low priority will be serviced in the last charge and there is a constant possibility that in some cases such orders will be rejected. The proposed method enables moderate this situation by using increasing the possibility of servicing the low-priority orders. The method can increase the efficiency of environmental monitoring and pollution emission control.
