Exploration and Development of Marine Renewable Energy in Fujian Province Towards Carbon Neutrality

To achieve peak carbon emission and carbon neutrality, marine renewable energy plays an essential role in energy transition in China’s coastal areas. Fujian Province is not only exposed to a shortage of traditional energy resources, but also urgently needs to change its current coal-based energy structure to reduce carbon emissions. In contrast to the scarcity of fossil fuels, Fujian Province has rich marine energy reserves, with an abundant supply of offshore wind, wave, tidal, and ocean current energy. Therefore, the active development of low-carbon and carbon-free marine energy can increase the energy supply and alleviate energy shortages. Furthermore, it can optimize the structure of the energy sector in this region. This study analyzed the energy structure of the Fujian Province, the effort needed to reach the carbon neutrality goal, the reserves of marine energy resources, the background of marine energy development technology, and socio-economic conditions. We believe that the development of the marine energy is a critical action towards solving the current energy resource limitations in Fujian and subsequently propose relevant suggestions for marine energy industry development in Fujian Province in terms of development ideas and pathways.

Strateška kontrola Arktika i mogući oružani sukob velikih sila

The geopolitical competition of great powers over the control of strategically important natural resources is an integral part of the political agenda aimed at achieving economic and thus military dominance on a global level. The territory of the Arctic, as the northernmost part of the planet Earth, has large reserves of natural resources (primarily oil and gas), the sovereign control and exploitation of which are contested by the countries that surround (a total of eight of them) this area, but also recently by countries that have granted themselves the status of "near Arctic state" like the People's Republic of China. The trend of accelerated militarization of the Arctic in the period after the closure of the Cold War can be interpreted as a consequence of the damaged relationship between the key actors of international politics and different perceptions of the future global order. The goal of this work is a systematic description of the dynamics of relations between Arctic states with a special focus on the USA (including NATO) and the Russian Federation and their activities in the military-defense sphere. To achieve the projected goal, the technique of content analysis of strategic documents, the technique of narrative analysis and historical comparative analysis was used. The results of this research indicate the increased interest of the great powers in controlling the Arctic, i.e. the natural resources present in this area, as well as the strategically important international traffic corridor, the Northern Sea Route. Accordingly, the engagement of the armed forces should enable the unhindered implementation of the defined political-economic activities of the Arctic states with the status of a great power.

Summary of the impact of aeolian sand environment on key parts of wind turbine

<p indent="0mm">With the global implementation of the double carbon plan, the wind turbine industry has developed rapidly recently. The wind and sand environments significantly impact the operation of wind turbines. Wind farms are typically located in an area with large reserves of wind resources and can coexist harmoniously with the local environment. Although the desert area has substantial wind energy reserves, it is frequently affected by windy and dusty weather. First, this paper summarizes the distribution of deserts and the corresponding usage of wind energy globally; then, it briefly describes the core factors of the dusty weather, namely, sand source, dust movement form, and dust weather characteristics; finally, the research on the influence of wind and sand on the key components of wind turbines in the wind-sand environment is reviewed, and the research prospect is discussed. The purpose is to provide a reference for the technicians engaged in relevant research, hoping to support the collaborative improvement of wind energy usage and the desertification environment.

The logistic dynamics of population growth as a prerequisite for global sustainable development

As a result of phenomenon of demographic transition, Verhulst’s logistic model is again relevant and allows to adequately reflect modern trends in population growth. The logistic dynamics of population growth can be considered as one of the main prerequisites for global sustainable development. Our research was based on the conclusions of most modern researchers, according to which the number of the Earth’s population cannot grow indefinitely. Such estimates are based on the limited reserves of the main exhaustible resources and on the current trend of declining birth rates. This indicates that the planet is moving into a new stationary state that corresponds to its increased industrial and technological capabilities, a higher level of health care. We built the logistic models that describe the dynamics of Earth population growth and its individual continents. These models make it possible to forecast the population size and its growth rates for the next 200 years. Obtained results open up an opportunity for regulation and optimal management of the Earth’s demographic resources.

Жамбыл облысының микрогидронимдерін зерттеудегі жасанды және табиғи су көздері атауларының көрінісі

A large number of natural and artificial water sources are found on the territory of Zhambyl region. This is due to the fact that in the territory located in the mountainous region, the names of rivers, lakes, streams, wells with rich reserves of water resources are often found, and the nature of hydrological objects is clearly indicated. It can be said that the terms defining geographical names that characterize natural water sources have an ecological and geographical basis. Natural water sources have played an important role in the economy and provide extensive geographical information from history. From modern historical and archaeological data it can be seen that the first human settlements were located near water bodies. The article analyzes specific data on the manifestations, formation and features of the names of artificial and natural water sources in the study of microhydrogems of the Zhambyl region. The names of water bodies (hydronyms) are based on hydrographic terms. With the help of the terms contained in the hydronyms, it is possible to determine the type, nature and geographical features of water bodies. Toponymic analysis, geoinformation methods of differentiation and drawing conclusions were used in the study of microhydronyms of Zhambyl region.

Prospects for the use of Arctic routes in the context of climate change and the implementation of the concept of sustainable development of the Arctic zone

The urgent need to solve environmental problems and meet the needs of people requires finding alternative ways to deliver goods in the most environmentally friendly and safe way. In addition, the climatic changes occurring on our planet open up additional prospects for the use of the Arctic for economic purposes, in particular, the use of the Northern Sea Route for cargo transportation. In the modern world economy, sea cargo transportation accounts for about 80% of all cargo transportation. The main cargo flow is carried out through the Southern Sea Route (SSR), along which goods are transported from Europe to Asia. For quite a long period of time, shipowners and logistics companies did not perceive the Arctic region as an alternative to traffic from Asia to Europe or North America, while navigation in the Arctic was much more than just transport shipping. At the same time, the situation has changed significantly in the 21stcentury. The interest in this region among the states of the Arctic zone, as well as other countries, is connected not only with the presence there of large reserves of mineral resources, solving geopolitical problems, but also the search for alternative sea routes for cargo transportation between Europe, North America and Asia. In connection with the blockade of the Suez Canal in March 2021, the question of the need to redirect cargo transportation to alternative routes – the Northern Sea Route (NSR), as part of the Northeast Passage, and the Northwest Passage became acute. The Suez Canal is the busiest and longest sea artery. In addition, this area is unsafe due to frequent attacks by pirates. Due to the geographical features of the SSR the presence of sufficiently narrow places along the route - under the condition of increasing traffic, does not contribute to the free passage of ships. Meanwhile, the active melting of the Arctic ice in the foreseeable future will allow navigation along Arctic routes at higher latitudes and without the escort of icebreaker transport. All of the above allows us to consider navigation in the Arctic latitudes as an actual alternative to the Southern Route, which will serve as the beginning of sustainable development of the Arctic region.

Tax aspects of the functioning of the electric car market in Ukraine

Introduction. A large-scale war in Ukraine leads to the destruction of a number of industries, the closing of factories, the emigration of human capital abroad, and the rise of energy prices. The experience of developed countries considers the development and use of ecological transport, in particular, the gradual replacement of gasoline, diesel and gas cars and trucks with electric vehicles, as one of the promising directions for overcoming crises. The production and operation of environmentally friendly electric cars is a tool for stimulating innovative production in the country. Goal.

The results. It has been proven that the market of electric cars can become a driver of the post-war reconstruction of Ukraine. It is in Ukraine that large reserves of resources for the full production of electric vehicles are concentrated. It is proposed to overcome the level of unemployment, create new jobs and attract investments in the construction of factories for the production of electric vehicles.

Washington's policy against the backdrop of fierce competition between the U.S. and China in Central Asia

The article identifies Washington's priorities in the process of implementing its policy towards Central Asia, especially in the context of strengthening Beijing’s position in the region which is its main military and economic rival. Fierce competition for the world influence has made Central Asia one of the priority regions of the post-Soviet space for both the United States and China, due to the presence of large natural resource reserves located here, as well as its important transit potential, which permits constructing suitable logistics there thus providing a close link between Europe and Asia. The reasons for the United States’ increased interest for this country are determined together with profound analysis of Washington’s ways and means on the way of implementing its policies toward Central Asia. The main levers used by the United States in the region are, first of all, its solid financial capabilities, though currently Washington is far behind Beijing in this area. At the same time, it seems that US inclination to take a leading position in the thus China aside will directly depend on the way to what extent the United States could become much more attractive in comparison with China on the way of implementing both countries’ ambitious policies toward the region.

Challenges In Optimizing Migration Costs From On-Premises To Microsoft Azure

The current paper analyzes the feasibility of a modular web application's migration procedure from on-premises to the cloud. Our focus is on identifying cost savings and options for hosting the application in the cloud. The research specifically examines the impact of architectural decisions records (ADR) on a modular monolith use case, utilizing .NET Core for the backend and Angular for the front end, with Clean Architecture as the design pattern.We investigate different cloud models (IaaS, PaaS, Serverless) considering project management's triple constraints (time, cost, performance). The study demonstrates that a modular monolith can be migrated with varying effort and costs depending on the chosen cloud model and technology stack. We explore optimizations such as resource utilization, licensing fees, and cost reduction through infrastructure reservations. Our findings show that the migration cost can range from a 20% increase with IaaS to approximately 70% cost reduction with the Serverless strategy compared to the on-premises environment, using equivalent resources.We also explore methods to lower expenses for each model, including resource modifications, Linux operating systems, and longer resource reservations. Considering limitations, we propose a two-stage migration strategy: initially lifting and shifting the application to IaaS with cost optimization, and subsequently migrating to PaaS for scalability and simplified resource management in the long term.

The Development of Tribology in Lubrication Systems of Industrial Applications: Now and future impact

Over the past 25 years, natural resources have been used up quickly, causing significant damage and contamination to the planet which is earth. Tribology, a new technology for keeping power and parts running, supported extremely fast and efficient coal and oil-powered machinery throughout history. Many different kinds of resource reserves, like those for power and parts, will be gone in a century. Revolutionary zero-emission and durability technologies are in high demand all over the world in order to create new, truly healthy and long-lasting lifestyles for humans and other living things in a symbiotic way. Tribology is expected to expand its technological innovation in order to support a new industrial trend and meet the requirements of the sector. At the moment, the primary factors influencing engine development are cost, performance, governmental requirements, and consumer requirements. In a few instances, the requirements are linked to tribology. For engines to last longer and be more reliable, tribology advancements that reduce friction and increase wear resistance will be crucial. The components under scrutiny are a part of the heavy-duty diesel engines’ valvetrain mechanism. The fuel injector places a lot of strain on the injection cam, making it one of the camshaft’s most problematic components. Lubrication plays a crucial role in avoiding cam failure caused by wear. The cam and roller contact, in any case, has shown to be one of the most provoking tribological plan challenges to handle. For lubricated contacts, the type and amount of wear are significantly influenced by the degree of separation between the surfaces. The term “specific film thickness” refers to this degree of separation and measures the degree to which asperities interact with one another in the lubricated contact. In order to predict lubrication regimes and, consequently, identify the injection cam’s likely wear zones, this paper focuses on measuring the oil film thickness in the cam-roller contact and other machine parts that follows. The results of the experiment (the observation of worn cam surfaces) are then confronted. In the near future, a multivariate analysis will be used to ascertain how the various parameters affect oil film thickness. The following stage will primarily focus on modeling injection cam wear, which will also include quantifying relationships between wear and a specific film thickness.

МЕТОДОЛОГИЯ УПРАВЛЕНИЯ РАЗВИТИЕМ ТЕРРИТОРИИ АРКТИЧЕСКОЙ ЗОНЫ НА ОСНОВЕ ТЕХНОЛОГИЙ ЦИРКУЛЯРНОЙ ЭКОНОМИКИ

The relevance of this study is due to the fact that modern society is entering a new round of innovative development with a characteristic increase in eco-activism and public demand for products of environmentally friendly industries, as well as the growing interest of business structures in saving scarce resources that are becoming more expensive through the massive introduction of waste-free technologies and lengthening cycles of consumption. The benefits of the transition to circular economy for regional systems lie in the creation of new jobs as they move from simply giving up some of the benefits created from non-renewable resources to designing long and multiple cycles of consumption. The natural wealth of the Arctic zone is a huge potential for the development of the Russian economy. Considering the large resource reserve of this region, the issues of increasing the efficiency of managing the socio-ecological and economic development of this territory based on circular economy technologies are timely and necessary. The goal is to develop methodological foundations for managing the socio-ecological and economic development of the Arctic zone based on the circular economy model. The object of research is the concept of circular economy. The subject of the study is the organizational and managerial relations that arise in the process of managing regional systems based on circular economy technologies. Research methodology: comparative and systematic approaches, as well as general theoretical methods of analysis, synthesis, generalization, comparison. As a result, the author reveals the essence of the circular economy, which consists in the adoption of cleaner production models, increased responsibility and awareness of producers and consumers, the use of renewable technologies and materials, as well as the adoption of suitable, stable policies and tools. The principles and tools for managing regional systems based on circular economy technologies are proposed. The necessity of transformation of the model of management of the socio-ecological and economic development of the Arctic zone through the use of elements of the circular economy is substantiated.

Optimization of production parameters of agricultural enterprises

The study substantiates the need to apply methods of economic and mathematical modelling of optimization of the production process of enterprises of the agrarian complex. The key elements of the various stages of development and construction of an economic and mathematical model of agricultural enterprises’ production resources that optimizes resource reserves for resource identification, judicious resource use, and enhancement of economic activity efficiency are taken into consideration. The proposed model may be used to analyze and discover resource potential reserves for businesses with any kind of ownership, as well as to identify elements of strategies to increase the economic activity of both the business as a whole and its individual units. The findings confirm that the employment of economic and mathematical approaches is efficient in evaluating agricultural firms’ resource potential as well as the optimization of raw materials, output, and sales. The process of modelling the activities of agricultural enterprises makes it possible to respond quickly to changes in demand for marketable products and make scientifically sound management decisions regarding the planning of production of its various types in order to maximize profits. Confirmation of the result is that the use of economic and mathematical methods is effective in assessing not only the resource potential of agricultural enterprises, but also the optimization of raw materials, production and sales. The process of modelling the activities of agricultural enterprises makes it possible to respond quickly to changes in demand for marketable products and make scientifically sound management decisions regarding the planning of production of its various types in order to maximize profits.

Research on the Cultivation of Employment-oriented Students' Entrepreneurial Ability in Vocational Schools

In recent years, the employment problem of graduates in vocational schools has become increasingly prominent, and the main reason lies in the lack of core competitiveness of students in vocational schools. Vocational schools shoulder the responsibility of cultivating entrepreneurial talents to meet the needs of society, focusing on improving college students' entrepreneurial literacy and practical entrepreneurial ability, and accumulating entrepreneurial human resources reserve for the country. Good professional ability is the basis of students' employment. Vocational schools are employment-oriented, so we should focus on cultivating students' professional ability. Therefore, courses should be set up according to the requirements of post professional ability. The entrepreneurship education mode of vocational school students from the perspective of industry-university cooperation not only helps to open up employment channels for college students and increase their employment chances, but also improves their employment quality and cultivates entrepreneurial talents needed by enterprises. This article discusses the cultivation of students' innovative consciousness from the perspective of employment, puts innovative consciousness at the core position of students' core competitiveness in employment, and analyzes the employment orientation of students in vocational schools from the perspective of the cultivation of development concept.

Возможности протокола резервирования ресурсов для повышения пропускной способности и надежности передачи трафика между системами коммутации

As a research task, the authors define the features of the use of the resource reservation protocol (RSVP) in modern networks of MPLS (Multi protocol label switching) technology, which provides an increase in the throughput of delay-sensitive voice and video traffic. The RSVP protocol allows you to transfer requirements for the level of Quality of Service (QoS) with reference to data flows. The article discusses the characteristics of the RSVP protocol. The use of RSVP of three reservation styles is considered, as well as an extension of RSVP that supports better QoS, the establishment of explicit routable paths (LSP) with or without reservation, the possibility of LSP redirection. The benefits of segment routing (SR) are discussed in giving the network operator more control over the network, simplifying the network, and supporting class of service. It also discusses the protection mechanisms for MPLS-TE tunnels to provide failover.

A Scenario-Oriented Approach to Energy-Reserve Joint Procurement and Pricing

We consider some crucial problems related to the secure and reliable operation of power systems with high renewable penetrations: how much reserve should we procure, how should reserve resources distribute among different locations, and how should we price reserve and charge uncertainty sources. These issues have so far been largely addressed empirically. In this paper, we first develop a scenario-oriented energy-reserve co-optimization model, which directly connects reserve procurement with possible outages and load/renewable power fluctuations without the need for empirical reserve requirements. Accordingly, reserve can be optimally procured system-wide to handle all possible future uncertainties with the minimum expected system total cost. Based on the proposed model, marginal pricing approaches are developed for energy and reserve, respectively. Locational uniform pricing is established for energy, and the similar property is also established for the combination of reserve and re-dispatch. In addition, properties of cost recovery for generators and revenue adequacy for the system operator (SO) are also proven. Simulations validate the effectiveness of the proposed mechanism.

Congestion Control in Autonomous Resource Selection of Cellular-V2X

Intelligent transportation systems have recently become a promising technology for future industry to provide safe, green, and automated driving. In this regard, the Third Generation Partnership Project (3GPP) has proposed to utilize cellular communication to enable direct communication between vehicles with and without cellular infrastructure assistance. 3GPP has introduced the Sensing-Based Semi-Persistent Scheduling (S-SPS) technique when coverage of the cellular system is absent. S-SPS faces resource collision and performance degradation problems when channel load increases in the network. This paper suggests a decentralized congestion control and transmission power control mechanism (TPC-DCC) with an adaptive threshold for the received signal as a combination method to decrease channel load in the network. Furthermore, this work introduces a novel channel load adjustment. The new adjusting algorithm is based on a constant difference between the upper and lower boundaries of channel load at each level to handle channel overload and provide more flexibility using DCC mechanisms. The interactions of the proposed algorithm with S-SPS and the Extended-Estimation Reservation Resource Allocation (E-ERRA) algorithms that the authors previously proposed are investigated. The results indicate that system performance can be substantially improved when the transmission power and reception threshold are adaptively adjusted to the proposed channel load adjustment. The results of E-ERRA with the proposed channel load adjustment method show promising results compared to S-SPS.
