Perfect modeling is essential to estimate the performance of PhV (Photovoltaic) modules in different environmental conditions. The comparison of the performance of solar cells with different models leads to the conclusion that the manufacturers did not provide the values of the resistance in series and parallel of the manufactured cell. Before installing a PhV system, a good ...

The article considers the bending of a two-support beam using the example of the simplest load option - a concentrated force applied in the middle of the span. The values of deformations in the middle of the span are calculated for various variants of the beam cross section. The calculation results were modeled using the Ansys program, version 22.2

This article considers the principal theoretical possibility of regulating a nuclear power reactor under changing operating modes conditions when external periodic disturbances take place in conditions of changing the operating mode. By the external periodic perturbation a downward change in the conditions of the heat sink was meant. The magnitude of the changes was preliminarily ...

In the article, the results of studies carried out during the formation logistics schemes for international transportation of export cargoes under the restrictions of the western direction for the Republic of Belarus. Research has established that the amount of freight charges for the logistics of transporting export cargo to the PRC depends on the type of shipment (the cargo can ...

A series of mathematical models and codes are developed to investigate the dendritic growth of Fe-0.82wt%C alloy. It is found that the small columnar dendrites are growing under the restriction of neighboring bigger ones and will be eventually combined to form the stronger columnar dendrites. With the decrease of cooling intensity, the primary dendrite arm spacing increases, and ...

Mn16Fe16CoxNi34-xGe7Si27（x=1，3，6，7.5，9）series alloy were prepared by vacuum arc melting technology under the protection of argon flow and structure and magnetocaloric effects of MnCoGe-FeNiSi composite material was investigated . Using X-ray diffraction (XRD) and vibrating sample magnetometer (VSM) method, structure and magnetocaloric effects of the alloys were analyzed, respectively. ...

In recent years the application of fiber in concrete is more and more extensive, this paper for, plant fiber, nano-fiber, steel fiber to make a relevant comparison of the classification, and discusses the fiber in the concrete in the relevant problems, I hope to provide readers with relevant reference around.

A new approach for the computation of electric fields is described, based on the response surface methodology (RSM) and geometric feature charge simulation method (GFCSM). And the novel combination of RSM and GFCSM is applied to calculate the electric field of the high voltage SF6 arc quenching chamber in this paper. The electric field distribution with higher calculation precision ...

The developed empirical relationships have practical significance and used for determine the structural composition of iron on known data of express-analysis and for optimization technical process of obtaining castings of ductile iron at Public corporation «Gomel foundry «TSENTROLIT».
