An Integrated Depok Smart City Evaluation

Given the complicated pressures brought on by the fast pace of urbanization, innovative and long-lasting solutions to the issues arising from urban expansion are needed. To ensure a greater standard of life for their citizens and make sustainable growth one of their long-term goals, cities will need to make more inventive, persistent, and successful changes to their infrastructure. Nonetheless, smart cities require complex solutions to problems involving ICT, economics, government, social issues, the environment, and transportation. The sustainability of smart cities is now a topic that academics, environmental policymakers, and governmental organizations are more interested in. Depok's smart city must be evaluated to determine its capacity to fulfill the desired vision to help implement the Movement Towards 100 Smart Cities. This study offers an evaluation approach for the Depok smart city. Three indices were used to construct an integrated evaluation approach: the IMD Smart City Index 2023, The Cities of the Future Index, and the Global Power City Index. None of the indexes' results include all six of the Depok Smart City's necessary dimensions. Thus, the advice was to merge the three indices into an integrated evaluation approach for evaluating the six primary dimensions of the Depok Smart City. The results of this study also offer a sample measurement statement according to Depok Smart City. Furthermore, follow-up actions that the government or stakeholders can take to improve Depok's smart city performance include implementing the integrated matrix indicators and evaluating their validity and relevance in the real world.

Hybrid Deep Neural Network Approaches for Power Quality Analysis in Electric Arc Furnaces

In this research, we investigate the power quality of the grid where an Electric Arc Furnace (EAF) with a very high load operates. An Electric Arc Furnace (EAF) is a highly nonlinear load that uses very high and variable currents, causing major power quality issues such as voltage sags, flickers, and harmonic distortions. These disturbances produce electrical grid instability, affect the operation of other equipment, and require strong mitigation measures to reduce their impact. To investigate these issues, data are collected from the Point of Common Coupling where the Electric Arc Furnace is fed. The following three main factors are identified for evaluating power quality: apparent power, active and reactive power, and distorted power. Along with these powers, Total Harmonic Distortion, an important indicator of power quality, is calculated. These data are collected during the full process of producing a complete steel batch. To create a Deep Neural Network that can model and forecast power quality parameters, a network is developed using LSTM layers, Convolutional Layers, and GRU Layers, all of which demonstrate good prediction performance. The results of the prediction models are examined, as well as the primary metrics characterizing the prediction, using the following: MAE, RMSE, R-squared, and sMAPE. Predicting active and reactive power and Total Harmonic Distortion (THD) proves useful for anticipating power quality problems in an Electric Arc Furnace (EAF). By reducing the EAF’s impact on the power system, accurate predictions will anticipate and minimize disturbances, optimize energy consumption, and improve grid stability. This research’s principal scientific contribution is the development of a hybrid deep neural network that integrates Convolutional Neural Networks (CNNs), Long Short-Term Memory (LSTM), and Gated Recurrent Unit (GRU) layers. This deep neural network was designed to predict power quality metrics, including active power, reactive power, distortion power, and Total Harmonic Distortion (THD). The proposed methodology indicates an important step in improving the accuracy of power quality forecasting for Electric Arc Furnaces (EAFs). The hybrid model’s ability for analyzing both time-series data and complex nonlinear patterns improves its predictive accuracy compared to traditional methods.

A Novel NR-DA-Based ANN for SHEPWM in Cascaded Multilevel Inverters for Renewable Energy Applications

Harmonics is the major power quality problem caused by nonlinear devices, leading to malfunction or operational halt of the system. Low-order harmonics increase vibration and heat generation in motors. Therefore, controlling harmonics in the output waveform is the prime target for industrial applications to avoid economic loss. Selective harmonic elimination pulse width modulation (SHEPWM) is one of the techniques used for eliminating or minimizing selected harmonics in the output voltage waveform. This paper utilizes the Newton-Raphson method and Dragonfly Algorithms to calculate optimum switching angles for a Cascaded H-bridge Multilevel inverter (CHBMLI). The algorithms use non-linear equations to calculate the Switching Angles of MLI. The Dragonfly algorithm requires several iterations to reach an optimum solution. For complex problems, this algorithm becomes computationally expensive and time-consuming. A lookup table addresses the limitation by offline training an Artificial Neural Network (ANN) to generate the optimum switching angle for a given modulation index. Neural Fitting Tool in MATLAB software is used to train the ANN model. The simulation is performed using MATLAB SIMULINK software for both 5-level and 7-level CHBMLI configuration. The Dragonfly algorithm-based ANN achieves THD 8.84% when the modulation index (M) equals 0.8 for a 7-level inverter and THD 14.91% for a 5-level inverter and effectively minimizes third and fifth-order harmonics.

Ethiopia and BRICS: Prospects and Challenges

This study examines Ethiopia's relationship with the BRICS group (Brazil, Russia, India, China, and South Africa), exploring both the opportunities and challenges this affiliation presents. As emerging economies gain global influence, Ethiopia's inclusion in BRICS represents a significant chance to leverage economic, political, and technological strengths. The research highlights the potential benefits for Ethiopia, including enhanced trade, investment, and technology transfer, which could drive the country's economic growth and development. However, Ethiopia also faces substantial challenges, such as infrastructure deficiencies, skill gaps, and regulatory barriers that may hinder its ability to fully align with BRICS frameworks. The study underscores Ethiopia's strategic motivations for engaging with BRICS, including accessing new markets and fostering innovation. It also addresses the risks of economic dependency and the need for a balanced diplomatic strategy with traditional Western partners. Through a mixed-method approach, the research combines quantitative and qualitative analyses to provide a comprehensive understanding of Ethiopia's position within BRICS. The study emphasizes the geopolitical significance of BRICS in reshaping global power dynamics and Ethiopia's potential role in this transformation. The study offers strategic recommendations to enhance Ethiopia's engagement with BRICS, aimed at a mutually beneficial partnership aligned with Ethiopia's development goals and regional influence. This contribution is crucial for policymakers and researchers interested in South-South cooperation and its impact on Africa's fastest-growing economies.

EVALUATION OF TECHNOLOGICAL PLASTICITY OF HIGH BORON CORROSION-RESISTANT STEEL DURING HOT DEFORMATION OF PIPES USED FOR SPENT NUCLEAR FUEL STORAGE

Statement of the problem. The sustainable development of the global nuclear power industry in the future depends on how effectively the problems of radiation safety and nuclear proliferation are addressed. Such problems occur, among other things, at the final stage of the nuclear fuel cycle – spent fuel management. This task is currently on the agenda of both the international community and national governments of countries that develop or intend to develop nuclear energy [1−3]. Today, in connection with ensuring the safety of nuclear energy, boron-containing steels are widely used in the world practice as a material for biological protection and for the manufacture of special equipment parts. This is due to the fact that the B10 isotope in steels provides neutron capture [4]. Hexagonal pipes made of high-boron steel were needed to shield the support cover of the compacted spent fuel storage facility at nuclear power plants. Corrosion-resistant steels alloyed with boron are widely used in the nuclear power industry due to their special nuclear properties. During the operation of nuclear power plants, fuel assemblies that have served their useful life must be stored in special storage facilities using containers – hexagonal tubes made of 04Сr14Ti3B2V steel. To reduce costs during in the construction and operation of NPPs, part of the spent nuclear fuel management should be performed at Ukrainian enterprises. This will provide a significant import substitution effect. To manufacture hexagonal tubes from 04Сr14Ti3B2V steel according to the ingot-hot deformation-profiling-heat treatment scheme, it is necessary to develop the parameters of hot deformation and subsequent technological operations. The use of these pipes in compacted spent fuel storage facilities of NPPs will allow to increase the storage capacity by 2 times, which will give a significant national economic effect Material and methods of research. Material used for the study was steel 04Сr14Ti3B2V (CS-82), smelted using two variants (vacuum-induction – “VI” and vacuum-induction followed by vacuum-arc remelting – (“VD”). Steel grade 04Сr14Ti3B2V belongs to high-alloy, corrosion-resistant ferritic steels with a high boron content of up to 2 %. The method of differential thermal analysis was used to study the phase transformation temperatures in the steel. X-ray diffraction and micro-X-ray spectral analysis were used to assess the phase state. The steel samples were tested for weldability After cooling, the welded samples were subjected to X-ray transmission [5]. Hot twisting tests and mechanical tests at high temperatures were also performed. The macro- and microstructure of the metal was studied. Results. The macro- and microstructure of steel was evaluated depending on the smelting method. The phase composition of the steel was studied. The study of the plastic properties of steel ChS-82 by means of penetration and hot twisting tests showed that the temperature range of maximum plasticity is in a wide range (from 1 025 to 1 150 0C) with a rather low resistance to deformation. During hot deformation in the temperature range of 1 175 0C and above, metal fracture was observed along the grain boundaries at the melting points of the Cr−Fe−B boride phase. The optimal temperature range for hot deformation of steel ChS-82 is 1 000−1 050 ⁰С. Scientific novelty. For corrosion-resistant high boron steel used for spent nuclear fuel storage, the temperature range of hot deformation was selected and the structural and phase composition was estimated, which will allow deforming the metal on the piercing mill and manufacturing pipes.

The Influence of the Meiji Restoration on the Rise of Militarism in Japan: An Analysis of Internal Reforms and External Influences

Before the Meiji Restoration, Japan was experiencing exploitation and oppression from Western imperialism as China did, and Japan was forced to sign a series of unequal treaties with Western countries. The oppression of imperialism made Japan realize the importance of having a strong army, therefore after the Meiji Restoration, the government decided to enhance Japans military capability to win the respect of Western countries and revise the unequal treaties that Japan was previously forced to sign. Later, Japans military power increased significantly due to militarism, which was why Japan defeated China in the First Sino-Japanese War and defeated Russia in the Russo-Japanese War. The victory of these wars made the country gain the respect of Western countries and made the government sure of the importance of a powerful military. The thing that made Japan become a great power was militarism, which was promoted by the Meiji Restoration, and this essay will study how the Meiji Restoration promoted the rise of militarism in Japan. The study has found that the impact of the Meiji Restoration on the rise of militarism in Japan can be divided into two parts. The first part is the internal factors, which are the military reformation exercised by the government and the governments education and publicity towards the people, the second part is the external factor, which is the influence received by the Meiji government from Prussia. These three factors played an important role in the rise of militarism in Japan.

Childhood, Migration and the Pursuit of Happiness in MIDDLE‐CLASS EAST ASIA

ABSTRACTThis special issue explores the shifting landscape of global middle‐class migration within and from East Asia by taking the relationship between mobility, parenting ideals and changing educational desires as its focus. Contributions explore how East Asian middle‐class families balance the emergent emphasis on their children's well‐being with the demands of global competitiveness as these often‐antagonistic desires are projected onto old and new migration destinations against the background of global geopolitical and economic power shifts. Instead of reifying the simplistic binary of hierarchical, achievement‐oriented East Asian ‘Confucian educational norms’ versus democratic, well‐being‐focussed Western ideals, the contributions offer a nuanced understanding of how these educational ideals coexist within the social, cultural, political and economic contexts of families. By carefully assessing the dialectically entwined intimate experiences of parents and children, the articles collected here set out to broaden our understanding of how middle‐class families in Singapore, South Korea, Japan and China attempt to negotiate the tension between prioritizing children's happiness and maintaining global competitiveness result in a variety of strategies from migrating to less obvious international destinations to crafting domestic alternatives. Taken together, the articles reveal consistent patterns of middle‐class migration and child‐rearing decisions that contest and reshape conventional notions of success, attesting to a shift in global middle‐class migration trends and to the importance of child‐rearing in migratory decisions.

The future image as a component of political subjective space: testing the conceptual model

The image of the future of youth is described in this paper and its relationship with the subjective space of politics is identified. The article provides a brief analysis of research on the image of the future within the framework of social and political sciences, describes the main theoretical approaches to analyzing the future image of youth. The authors give their own conceptual definition of the future image as a component of the political subjective space, a set of symbolic, ideological and cultural meanings that determine the orientation and behavior of various political actors. The authors as a methodology use focus group interviews, online questionnaires of youth representatives in order to verify the conceptual model of the study. The dynamic nature of the future image as a part of political subjective space is determined by a system of institutions, agents and factors of socialization. Five key components have been identified in the structure of the future image: content, value, emotions, activity and technology. Four projection levels of the future image are defined: personal, group, projection at the level of the macro community and global. The study indicates the predominance of personal projection in the respondents' ideas about the future. Despite the presence of worries and fears for their personal future, young people are generally confident in their own future and believe that the Russian state will continue to play an important role as a world power. An important characteristic of the future image is the subjectivity of its bearer, the degree of activity or proactivity and the willingness to take responsibility for their own future and the future of their families, local community, region, country, and the world. Locus control, that is, a subjective assessment of the factors (personal efforts or external circumstances) on which the future depends, according to the study, is associated with the degree of confidence in the future, the formation of a positive future image. The predominance of civic identity in the hierarchy of identities is also revealed. Young people feel responsible for the future of their country. At the moment, Russian civic identity has a positive impact on the future image of young people. It is significant that among students studying in the Luhansk People's Republic, the level of concern about the future is higher, the level of civil identity is lower, which indicates that the task of forming civil identity should be prioritized in the new regions of the Russian Federation.

Identifying the spatio-temporal distribution characteristics of offshore wind turbines in China from Sentinel-1 imagery using deep learning

ABSTRACT Offshore wind power is a crucial clean energy source for coastal countries and advances blue economies. Accurate spatial mapping of offshore wind turbines supports energy assessment and the sustainable development of marine resources. Offshore wind power has developed rapidly in China, but the spatiotemporal distribution characteristics of offshore wind turbines and farms remain poorly understood. Extracting nearshore small targets from Sentinel-1 synthetic aperture radar images remain challenging due to noise from the rough sea surface background and the diverse substrate types in offshore wind turbine (OWT) distributions. Here, to address these issues, we first created a dataset of China’s offshore wind turbines (COWTs) that contained typical substrate types (e.g. seawater and tidal flats). Then, a deep learning model integrating an attention mechanism and receptive fields was used to accurately detect COWTs. The well-trained model was used to detect the changes in COWTs from 2015 to 2022. Our model detected an increase in the number of offshore wind farms in China from 7 to 114 (clusters counted as an offshore wind farm), while COWTs increased from 305 to 6451 from 2015 to 2022. The Taiwan Strait exhibited the highest wind speeds, yet the Jiangsu and Guangdong regions had the most installed turbines. Over 90% of COWTs were located in areas with offshore wind energy resources less than 500 W/m3, indicating a mismatch between COWT installation and wind resource distribution. This study demonstrated temporal and geographical generalizability, which is promising for global wind power detection. Our analysis of spatiotemporal variation in COWTs facilitates informed decision-making for future field establishment and sustainable marine planning.

China’s Rise and U.S.–Iran Standoff: An American Perspective

There has been a notable link/correlation between the rise of China and U.S.–Iran standoff in recent years. The year 2012 marks a watershed moment in U.S. strategic calculation on its relations with China and Iran. Before that year, China was not a peer competitor capable of challenging U.S. preeminence on the world stage and Iran was merely a regional adversary. After 2012, U.S. intelligence reports have consistently assess that China is the only great power with the intent and ability to undermine the liberal world order and its growing ties with U.S. adversaries, Iran included, will pose the biggest threat to U.S. and Western interests. The China factor has become an independent variable in U.S.–Iran relation, and as Beijing continues to grow its economic and military power, the United States will resort to more hawkish policy toward China and Iran, further escalating the U.S.–Iran standoff. Tehran will continue to play a crucial role in its asymmetrical relationships with Beijing and Washington as the two superpowers seek their respective leverage in the triangular relationship to outcompete the other party.

The European Response to US Expansion in the Mid-Nineteenth Century

The territorial expansion of the USA in the 1840s represented an important phase on its way to becoming a world power. Historians have paid considerable attention to US foreign policy during this period but have largely neglected the significant impact of US expansion on Europe. Whereas they have written a great deal about European reflections on American democracy or slavery, they have largely overlooked the geopolitical response that US expansion provoked among Europeans during that decade. This omission is surprising given the fact that this reaction spread not only in governmental circles but also among the broad public: the policy of the USA and its position in the Americas became an important topic with serious consequences for both sides of the Atlantic. Europeans often criticized the USA for its aggressive policy, and they feared that with the rise of its power it would behave in the same way in all parts of the world. The article's principal aim is to reveal the European response to US territorial expansion and how the repercussions of this response on the USA contributed to the rise of pan-Europeanism, nationalism, imperialism, and colonialism from the mid-nineteenth century.

Computational Fluid Dynamics Analysis on Proton Exchange Membrane (PEM) Fuel Cell Performance using Honeycomb Flow Channel

Proton exchange membrane fuel cell (PEMFC) systems have the ability to meet our energy demands in the near future since they are green, economical, and clean. They can also use hydrogen as a direct fuel. One of the key design factors influencing the PEMFC's performance is flow field configuration. The configuration of the flow channel in a PEMFC has a profound effect on reactant distribution and water management within the fuel cell. Current study aims to ameliorate fuel cell (FC) performance, water management, and pressure drop (PD) across channels. ANSYS Fluent 18.2 software, including its PEMFC add-on module, is utilized to execute a computational fluid dynamics (CFD) simulation of a 3D model of a PEMFC with a flow channel shaped like a honeycomb structure. A polarization curve, as well as factors such as PD, hydrogen and oxygen concentrations, membrane water content, and current density distribution along flow channels, have been included in the simulation results. The findings suggest that when the FC is operated at 0.45V, homogeneous reactant consumption and greater power and current densities are achieved, and, water generation is high across the Membrane Electrode Assembly (MEA).

The potential role of concentrated solar power for off-grid green hydrogen and ammonia production

This paper investigates the potential role of concentrated solar power (CSP) in off-grid green electrolytic hydrogen and ammonia production using an open-source techno-economic assessment optimisation model. The green ammonia plant comprises a flexible Haber-Bosch loop, an electrolyser park, a desalination plant, storage systems (thermal, electrical, and hydrogen), and a power supply optionally including wind power, solar photovoltaic (PV), and CSP (solar tower or parabolic trough collectors). Various system configurations and cost assumptions are tested to evaluate when CSP technologies are economically viable for green fuel production. Results demonstrate that CSP and thermal energy storage (TES) technologies can play a minor but useful role in providing nighttime power supply to the ammonia plant, in combination with onshore wind power and electrical storage. Solar PV with 1-axis tracking remains the primary power provider, and the optimal system always includes large-scale hydrogen storage. In the cheapest configuration, the LCOA reaches 646 €/tNH3. With an 80% reduction in CSP and TES costs, CSP technology becomes a major player in power production. In scenarios where hydrogen storage is not feasible and the ammonia plant lacks full flexibility, a 20% cost reduction (to 2750 €/kW) is enough for them to become major power providers.

The Greatest Name of God: ʿAlī ibn Abī Ṭālib as a cosmic image in Rajab al-Bursī's Mashāriq al-anwār

Abstract ʿAlī ibn Abī Ṭālib (d. 40/661)—a revered figure in Islamic history as both the first Shiʿi imam and the fourth caliph—serves as a significant image of sacral power in the Persianate world and beyond. ʿAlī's authority underwent a profound reimagining in the early modern era as he emerged as a captivating imperial emblem from the Timurid renaissance to the Safavid revolution, rivalling other prominent figures of political authority such as Chinggis Khan (d. 1227), and becoming a symbol of human perfection for both Sunni and Shiʿi intellectuals alike. ʿAlī transcended his role as a Shiʿi imam to assume the status of a cosmic figure, gradually becoming an ideal symbol for imperial branding. However, there is little scholarly knowledge and appreciation of his changing role in this period. This article examines how al-Ḥāfiẓ Rajab al-Bursī's (d. circa 814/1411) Mashāriq al-anwār, which has remained highly popular throughout the Persianate and Shiʿi world, contributed to the reshaping of ʿAlī's image, portraying him as the quintessential archetype of sacral power and unmatched authoritative feats.
