    Opis:
    With the increasing number of electric vehicles (EVs), the disordered charging of a large number of EVs will have a large influence on the power grid. The problems of charging and discharging optimization management for EVs are studied in this paper. The distribution of characteristic quantities of charging behaviour such as the starting time and charging duration are analysed. The results show that charging distribution is in line with a logarithmic normal distribution. An EV charging behaviour model is established, and error calibration is carried out. The result shows that the error is within its permitted scope. The daily EV charge load is obtained by using the Latin hypercube Monte Carlo statistical method. Genetic particle swarm optimization (PSO) is proposed to optimize the proportion of AC 1, AC 2 and DC charging equipment, and the optimal solution can not only meet the needs of users but also reduce equipment investment and the EV peak valley difference, so the effectiveness of the method is verified.

    Opis:
    GAP and HTPB are polymers on which the copolymer obtained in our work is based. The following report indicates how to perform the polymerization reactions for these two polymers in order to obtain a copolymer that combines their individual positive physico-chemical properties. It demonstrates how the ratio of substrates and reaction conditions affect the polymer properties. It has been shown that increasing the amount of epichlorohydrin attached to HTPB significantly affects the copolymer viscosity. This has a later effect on polymer processing, as well as on the hydroxyl values being too low. This is important for the subsequent production of polyurethanes. Analysis of the results allows the reaction conditions to be designed so as to generate a polymer with the best properties. The reactions were carried out in two stages. The first stage was the connection of polyepichlorohydrin (PECH) to HTPB, and the second was azidation of the resultant PECH-HTPB-PECH copolymer. The influence of the amount of epichlorohydrin attached to HTPB on the copolymer properties (e.g. viscosity) was demonstrated. Analysis of the second stage, the preparation of the GAP-HTPB-GAP copolymer (by azidation of the PECH-HTPB-PECH copolymer), showed that the nitrogen content in the copolymer has a significant effect on the viscosity and heat of polymer combustion.

    Opis:
    This work concerns the study of the coatings for the ultrasound frequency range as a quasi one-dimensional phononic crystal structure protecting a sea object against high resolution active sonar in the frequency range most commonly found for this type of equipment. The topology of the examined structure was optimized to obtain a band gap in the 2.2-2.3 MHz frequency band. For this purpose, a genetic algorithm was used, which allows for optimal distribution of individual elements of the ultrasound multilayer composite. By optimal distribution is meant to achieve a structure that will allow minimal reflectance in a given frequency range without height reflectance peaks with a small half width. Analysis of the wave propagation was made using the Transfer Matrix Method (TMM). As part of the research, 15 and 20-layer structures with reflectance at the level of 0.23% and 0.18%, respectively, were obtained. increasing the number of layers in the analyzed structures resulted in finding such a distribution in which a narrow band of low reflectance was obtained, such distributions could also be used as bandpass filters. The use of a genetic algorithm for designing allows to obtain modern coatings, the characteristics of which result from the structure.

    Opis:
    For obvious reasons, models for decision-making under severe uncertainty are austere. Simply put, there is precious little to work with under these conditions. This fact highlights the great importance of utilizing in such cases the ingredients of the mathematical model to the fullest extent, which in turn brings under the spotlight the art of mathematical modeling. In this discussion we examine some of the subtle considerations that are called for in the mathematical modeling of decision-making under severe uncertainty in general, and worst-case analysis in particular. As a case study we discuss the lessons learnt on this front from the Info-Gap experience.
