Objectivity in Historiography: A Comparative Analysis of Marxist and Postmodern Approaches
Статья научная
This article analyzes the problem of objectivity in historiography in a comparative way, within the context of Marxist and postmodern approaches. The aim of the study is to determine the place, possibilities, and limitations of objectivity in the approaches of both theoretical directions to the science of history. While Marxist historiography explains objectivity through the principles of class analysis and historical materialism, the postmodern approach emphasizes the relative and constructive nature of historical knowledge. The article presents the theoretical foundations of both directions, methodological differences, and critical views on the claims of objectivity. Also, the application of these approaches is compared using a specific historical event as an example. As a result, it is determined that the concept of objectivity in historiography is controversial and variable, and Marxist and postmodern theories approach this concept from different directions.

On some issues of judicial practice in human trafficking cases
Статья научная
Human trafficking continues to be one of the serious problems of the modern world community. The authors made an attempt on the basis of a comprehensive study (legal analysis of the composition of human trafficking and the study of judicial practice) to identify problematic issues when considering cases of this category, in order to ensure uniform approaches and develop a legal position. Eighteen sentences posted in the public domain in the Judicial Cabinet service, reviewed by the country's courts from 2015 to 2022, were studied. The data of official statistics are analyzed, the latency of crimes related to human trafficking is noted. The “facets” of human trafficking as a legal phenomenon in the history of national criminal legislation are traced. As possible ways to increase the effectiveness of countering trafficking in persons, as well as bringing domestic legislation into line with international law, it is proposed to include in the dispositions of Articles 128, 135 of the Criminal Code of the Republic of Kazakhstan an indication of the methods of committing crimes, differentiate the composition of trafficking in persons and trafficking in minors depending on the nature and purpose of the actions committed, systematically summarize judicial practice in cases of about human trafficking.

On the Comparative Study of the Kyrgyz Epic “Manas” and the Ancient Indian Epic “Mahabharata”
Статья научная
The heroic epic Manas, due to its grand scale and fantastically rich content, as well as its artistic perfection, figurative expressiveness, and the wealth of both verbal and visual means, holds a well-deserved place among the outstanding monuments of the world’s epic heritage. Comparative analysis of Manas with other world epics contributes to a deeper and more comprehensive understanding of its narrative and artistic features. According to researchers, in the Middle Ages, the ancestors of the Kyrgyz people were part of the Great Turkic Khaganate, which maintained cultural ties with many countries, including India. There are studies that confirm this historical connection. This article presents a comparative analysis of the great Indian epic Mahabharata (The Tale of the Great Bharata), translated by Nurgazy Kemelbaev and Kenesh Jusupov, and the work Tengir Manas in the version by Ashym Zhakypbekov. The study is aimed at identifying similarities and differences in the prose versions of these epic narratives. Examining typological parallels between the Indian epic Mahabharata and the Kyrgyz epic Manas allows for a deeper exploration of the originality of the latter, as each epic is a unique cultural monument shaped by the specific cultural, historical, and mental characteristics of its people.

The accommodation of renewable energy is driving the development of energy storage technology, and shared energy storage has gained widespread attention because of its decentralized nature. In the optimal scheduling of shared energy storage, the problem of benefit distribution among multiple subjects is faced, so a shared energy storage plant operation optimization method based on Nash bargaining theory is proposed. The article constructs a joint model of shared energy storage plants and industrial users, establishes the cooperative operation model of each operator based on Nash bargaining theory, equates this nonconvex nonlinear problem into two subproblems of system revenue maximization and power transaction payment bargaining according to the mean value inequality, and uses the alternating direction multiplier method to solve them in a distributed manner. The algorithm selects three typical industrial users to participate in the joint system of shared energy storage, and through comparative analysis before and after cooperative bargaining, it is concluded that the proposed optimization method can effectively improve the benefits of each subject, while promoting the accommodation of new energy.

Optimal design of heating boilers
Статья научная
Instead of a regular flywheel, it is possible to install a lightweight, with a variable moment of inertia on the electric unit, which will accelerate faster, which means it is faster to enter the mode of the rated frequency of the generator output voltage. In a mode close to the nominal speed of rotation, the moment of inertia will increase sharply, which will allow more mechanical energy storage, which will not allow to slow down the speed of the internal combustion engine, so it is better to damp (smooth out) the low-frequency external disturbances from the side of the electrical network.

The integrated energy system (IES) is an effective way to achieve the “carbon neutrality and emission peak” goal. In order to further explore the role of the adjustable potential of demand side on carbon emission reduction, an optimized operation model of IES considering the demand response under the carbon trading mechanism is proposed. Firstly, according to the characteristics of load response, the demand response is divided into two types: price-type and substitution-type. The price-type demand response model is established on the basis of price elasticity matrix, and the substitution-type demand response model is constructed by considering the conversion of electricity and heat. Secondly, base-line method is used to allocate free carbon emission quota for the system and considering the actual carbon emissions of gas turbine and gas boiler, a carbon trading mechanism for the IES is constructed. Finally, a low-carbon optimal operation model of IES is established, whose objective is to minimize the sum cost of energy purchase, cost of carbon transaction and cost of IES operation and maintenance. The effectiveness of the proposed model is verified through four typical scenarios. By analyzing the sensitivity of demand response, heat distribution ratio of gas turbine and the operating state of the system under different carbon trading prices, it is found that reasonable allocation of price-type and substitution-type demand response and heat production ratio of gas turbine is beneficial to improve the operating economy of the system. Making reasonable carbon trading price can realize the coordination of system economy and low carbon.

Optimal operation of integrated energy systems based on multi-energy complementarity
Статья научная
Complementary multi-energy operation is an inevitable trend in the development of integrated energy systems, and the construction of a fair and reasonable distribution method among multiple stakeholders is the key to realizing complementary multi-energy operation. Integrated energy systems have important applications for achieving sustainable energy development and building a green, low-carbon society, while the complex internal energy structures and equipment coupling relationships pose challenges for their operational optimization. Taking advantage of the interactive and complementary relationship between power and heat on both the supply and demand sides, energy storage devices are used on the supply side to realize the thermo-electrolytic coupling of the combined supply equipment and to enhance the multi-energy supply capacity of the system through each energy conversion device. On the demand side, load types are classified, and the elasticity of electrical loads and the diversity of system heating methods are used to construct a comprehensive energy demand response model with time shifting and curtailment responses of electrical loads and responses of heating load supply methods, and to propose a response compensation mechanism. On this basis, with the objective of minimizing the sum of system operation cost and response compensation cost, the mathematical model for optimal operation of integrated energy systems based on multi-energy complementarity is established, taking into account the equipment operation and dispatchable load resource constraints on both the supply and demand sides. Simulation results and comparative analyses based on arithmetic examples show that: synergistic optimization of both supply and demand, taking into account multi-energy complementarities, can effectively improve the flexibility and operational economy of the system.

Combined with domestic and foreign literature, the research progress, key parameters and existing problems of flat-panel solar collectors are analyzed. On this basis, the thermal efficiency of flat-panel solar collectors is studied by means of experiments and numerical simulations. This paper introduces and analyzes the structural characteristics of flat-panel solar collectors. Based on the structural characteristics of flat-panel solar energy and research at home and abroad, the influence of the structural parameters of each flat-panel solar collector on the collector performance was studied. According to the heat transfer process and structural characteristics of the collector, the heat energy equation of the collector is established, and the calculation process of the heat loss of the collector is simplified according to the existing research, and the calculation of the heat loss coefficient is an empirical formula. In order to facilitate the experimental study, an efficiency factor and a heat transfer factor are introduced, and the temperature of the fluid at the inlet of the collector is used to replace the surface temperature of the heat-absorbing plate, which is difficult to measure. The calculation program is used to obtain the influence data of each key parameter of the collector on the thermal efficiency and use Origin to process the data to visualize the influence of each parameter on the thermal efficiency. On this basis, a variance analysis method is proposed to optimize the collector. Based on the PYTHON software, the calculation program is written according to the variance analysis method, and the key parameters that will greatly affect the instantaneous efficiency of the collector are combined in pairs, and the optimal collector parameter combination corresponding to the maximum instantaneous efficiency is studied. This research has a certain guiding effect on the utilization of solar energy.

Optimizing the time costs of passenger transport of people with disabilities
Статья научная
The paper dwells on a mathematical model of the logistical system of transport services for persons with disabilities, and there have been analyzed factors that affect the time spent on their transportation. When developing methodology for optimizing the time costs of passenger transport of persons with disabilities, the following two basic transportation services have been taken into account: “Social Taxi”, which will transport only people with special health; b) vehicle system in combination with urban passenger transport, which will transport representatives of the group of people with restricted mobility together with all other passengers. The study found that in the case of insufficient accessibility to the required environment, by the increase in the demand of disabled people for transportation by “social taxi”, travel costs are increased that results in increasing total costs of the carrier. When determining the expenses of passengers, it is necessary to take into account the additional time, which the disabled persons need for boarding and alighting in buses at the stopping points, on average 2-3.5 minutes.
