Particle swarm optimization based on data driven for EV charging station siting

Charging stations are an important support facility for electric vehicles (EVs). Nowadays, the EV industry is developing rapidly, however, the imperfect construction of charging stations or the unreasonable choice of location has seriously reduced the desire of people to buy EVs and led to the problem of difficult charging of EVs in many areas. At present, the research field of EV charging station siting suffers from the inability to quickly and accurately calculate the optimal solution for charging station siting. In this regard, a particle swarm optimization based on deep neural networks modified boundaries (DNNMBPSO) is proposed for solving the problem. DNNMBPSO reduces the convergence value of the objective function by applying deep learning to modify the boundary of the particle swarm optimization. DNNMBPSO is an algorithm that combines heuristic and data driven. In this study, DNNMBPSO is applied for siting study in a system having 50 alternative points, 500 alternative points, and 1000 alternative points and a case of siting of electric vehicle charging stations in Nanning, Guangxi, China. The convergence value of the DNNMBPSO-based objective function is found to be at least 5.5 %, 1.7 %, 8.23 % and 14.7 %, lower compared to genetic algorithms, African vulture optimization algorithm, particle swarm optimization, and grey wolf optimization algorithms, respectively. Traditional heuristic optimization algorithms cannot find optimal solutions in large-scale systems, while DNNMBPSO shows feasibility in large-scale systems.

Aspectual Features of Some Circumstantial Clauses in Italian Translation (Based on a Corpus of Works by Georgi Gоspоdinov

The article takes a cursory look at the translation from Bulgarian to Italian of some types of circumstantial sentences, where a difference in type is observed. The translation of perfective or imperfective constructions is a challenge for both the translator and the learners of the Italian language, since the ways of expressing the verb form in Italian are different from those in Bulgarian. In the Bulgarian language, the type is expressed through morphological indicators, while the Italian language shows the type through the verb tenses and the opposition between them. The analysis of the corpus of examples shows the type difference between original and translation, where some kind of modality is also present, and that these type differences do not significantly affect the overall meaning of the examples under consideration.

Review and Reflection on the Construction of Ecological Moral Education in China and Abroad

At present, China is vigorously promoting the formation of new quality productive forces that will enable high-quality development, and the new quality productive forces themselves are green productive forces, which translates into the field of education, where the greening of education is to be promoted. Moral education is located in the first of the "five educations" in Chinese education, and it is undoubtedly of great significance to expand moral education from interpersonal moral education to ecological moral education. The main problems facing the construction of ecological moral education include lagging in the new direction of "big moral education," insufficient exploration of the mechanism of educational articulation, and imperfect construction of the relationship structure of various elements of moral education in schools. Based on this, we review the development and research on the construction of ecological and moral education in China and foreign countries and reflect on the implications for the construction of ecological and moral education in China and foreign countries to strengthen the government's implementation and supervision of ecological, moral education, to enrich and improve the construction of ecological, moral education curricula in schools, and to set up a platform for cooperation on "big ideology and politics" in order to promote the popularization of ecological, moral education.

ANALYSIS OF E-COMMERCE DEVELOPMENT OF AGRICULTURAL PRODUCTS IN PANZHIHUA UNDER THE INFLUENCE OF COVID-19

In recent years, agricultural e-commerce has improved a lot with the support of national policies. During the COVID-19 epidemic, the “no-touching” consumption model was used in agricultural e-commerce, which helped upgrade and optimize the agricultural industry chain. Due to this, agricultural products are prevented from being hoarded. The online sales of agricultural products in Panzhihua City have exceeded 900 million yuan now, showing a steady upward trend. This thesis intends to research the development of agricultural e-commerce in Panzhihua under the influence of the Covid-19 epidemic to analyze the current situation of agricultural e-commerce in Panzhihua, to find the main existing problems, such as the lack of e-commerce professionals and the imperfect construction of logistics infrastructure. Besides, by adopting the method of literatureresearching and case-analyzing, some possible ways to help improve agricultural e-commerce of Panzhihua more smoothly will be explored. The significance of this study is to a faster speed of the agricultural economy of Panzhihua and to drive the development of rural agricultural ecommerce in Panzhihua to a higher level.

Comparison of Herding Effect Between Developed Countries and Developing Countries

How to properly invest in the stock market is a hot issue of social concern, and some studies have shown that the herding effect will have a certain impact on the market stability and market efficiency of the stock market, and the herding effect between countries with different levels of development can be studied in more depth. The research topic of this paper is the study of herding effects in countries with different levels of development. The research methodology of this paper is as follows: developed and developing countries are divided into two categories, and four countries, the United States, the United Kingdom, China, and Indonesia, are selected to explore the causes and effects of the herding effect in developed and developing countries, respectively. The study found that the herding effect was more pronounced in developing countries compared to developed countries. The herding effect is more pronounced in developing countries because of the relatively imperfect construction of financial markets, the lack of financial literacy of the people, and so on, so these internal factors lead to the herding effect. In contrast, developed countries need to pay more attention to the herding effect caused by external influences such as epidemics and financial crises.

Bayesian inference and calibration of magnetic diagnostics.

The magnetic diagnostics across TAE Technologies' compact toroid fusion device include 28 internal and 45 external flux loops that measure poloidal flux and axial field strength, 64 three-axis (radial, toroidal, and axial) Mirnov probes, and 22 internal and external, axial-only Mirnov probes. Imperfect construction, installation, and physical constraints required a Bayesian approach for the calibration process to best account for errors in signals. These errors included flux loops not fitted to a perfect circle due to spatial constraints, Mirnov probes not perfectly aligned against their respective axes, and flux pickup that occurred within the insert (feedthrough) of the Mirnov probes. Our model-based calibration is derived from magnetostatic theory and the circuitry of the sensors. These models predicted outputs that were compared against experimental data. Using a simple least-squares optimization, we were able to predict flux loop data within 1% of relative error. For the Mirnov probes, we utilized Bayesian inference to determine three rotation angles and three amplifier gains. The results of this work not only gave our diagnostic measurements physical meaning, but also act as a safeguard to spot when instruments have malfunctioned, or when there is an error in database maintenance. This paper will go into the details of our calibration procedure, our Bayesian modeling, and the accuracy of our results compared to experimental data.

Revisiting the latent structure of negative symptoms in schizophrenia: Evidence from two second-generation clinical assessments

BackgroundNegative symptoms are core symptom of schizophrenia, and many previous research studied the latent structure of negative symptoms based on a single measurement scale. Applying two second-generation negative symptom scales to the same sample can address measurement-invariance of latent structure. MethodsThree-hundred-and-five schizophrenia patients were assessed using the CAINS and the BNSS. Confirmatory Factor Analysis (CFA) tested four competing factor-models: (1) a 1-factor model; (2) a 2-factor model comprising the motivation and pleasure (MAP) domain and the diminished expression (EXP) domain; (3) a 5-factor model comprising anhedonia, avolition, asociality, blunted affect and alogia; (4) a hierarchical model comprising the “first-order” 5-domain factors and the “second-order” MAP & EXP factors. ResultsThe CFA results for the data of the CAINS showed that the 2-factor model had the best data fit over the other competing models. The CFA using the BNSS data in the same sample also supported the superiority of the 2-factor model. Lastly, after combining the items of the BNSS and CAINS together in the same sample for CFA, the 2-factor model prevailed over the other competing models. ConclusionsThe 2-factor model appears to be measurement-invariant latent structure of negative symptoms. The novel method of combining the items of the CAINS and BNSS might have circumvented the possible imperfect construct of a single scale. Our findings support the MAP and EXP factors as the latent structure for negative symptoms.

Quantum Readout of Imperfect Classical Data.

The encoding of classical data in a physical support can be done up to some level of accuracy due to errors and the imperfection of the writing process. Moreover, some degradation of the stored data can happen over time because of physical or chemical instability of the system. Any readout strategy should take into account this natural degree of uncertainty and minimize its effect. An example are optical digital memories, where the information is encoded in two values of reflectance of a collection of cells. Quantum reading using entanglement, has been shown to enhances the readout of an ideal optical memory, where the two level are perfectly characterized. In this work, we analyse the case of imperfect construction of the memory and propose an optimized quantum sensing protocol to maximize the readout accuracy in presence of imprecise writing. The proposed strategy is feasible with current technology and is relatively robust to detection and optical losses. Beside optical memories, this work have implications for identification of pattern in biological system, in spectrophotometry, and whenever the information can be extracted from a transmission/reflection optical measurement.

A Review on the Overall Optimization of Production–Living–Ecological Space: Theoretical Basis and Conceptual Framework

The 18th National Congress of the Communist Party of China put forward the optimization of territorial space development patterns as the primary measure of ecological civilization construction, and put forward the goal of “promoting intensive and efficient production space, livable and moderate living space, and beautiful (picturesque scenery) ecological space”. Through literature research and summing induction, this paper combs the research progress of the overall optimization of “Production–Living–Ecological” space (PLES) systematically. It is found that the existing work mainly focuses on the overall optimization of PLES from the perspectives of land-use quality, land-use suitability evaluation, resource and environmental carrying capacity, and comparative advantages. However, due to the lack of understanding of the scientific connotation of PLES, and the imperfect construction of quantitative identification methods and classification system, there are many problems in the technical approaches of the overall optimization of PLES, which remain to be clarified. In the future, the technological approach to the overall optimization of PLES should be guided by the vision of building a beautiful China, with the theory of a human–Earth coupling system as the core, and systematically build a theoretical system and technical framework to identify and optimize territorial space.

With the development of the e-commerce industry, behind the prosperity of Internet e-commerce, it is also bound to face the problems of industry development, such as the scarcity of talents, imperfect construction of the rule of law, logistics services do not match. This paper analyzes and discusses the difficulties of e-commerce development from the characteristics of the current situation of e-commerce development in China, and puts forward corresponding countermeasures. E-commerce may encounter different problems and difficulties in the process of development, but it is believed that through the joint efforts of the government and all parties, it will be continuously improved and eventually provide more convenient services for people's lives.

Problems and Solutions of Construction Budget Overruns in China's Engineering Projects

The rapid development of the construction industry has driven the construction of engineering projects in China. However, there are currently many construction projects with budget overruns, resulting in reduced economic benefits of the project. Therefore, this paper elaborates the importance of construction budget of engineering projects, and then proposes the reasons for construction budget overrun of engineering projects: imperfect construction budget plan, lack of supervision in the implementation of construction budget plan, insufficient level of cost management personnel, and construction materials affected by the supply market. Finally, we propose measures to solve the budget overrun of engineering project construction: improve the project construction budget plan, strengthen the supervision of the implementation of the project budget plan, improve the professional skills of budget staff, and stabilize the supply price of construction materials.

Study on the Operation Mechanism of Categorized Protection System for Kunjing Children

The protection of the rights and interests of Kunjing children is related to the national economy and people's livelihood. In recent years, the categorized protection policy for children in needs is the focus of the government and academia, but the related research does not pay close attention to the longitudinal context of its internal operation. Based on this, this paper adopts the method of qualitative research to study the operation mechanism of categorized protection for children in needs through field investigation and explore the problems in the process of matching and implementation of protection content by constructing the operating framework of "monitoring-evaluation-treatment". The study found that at present, there are still some problems in the categorized protection of children in needs in the country, such as imperfect construction of categorized protection policy, insufficient protection of institutions and professional personnel, difficult policy implementation and so on. In this regard, the country should promote the further implementation of categorized protection for children in needs by promoting the combination and perfection of protection projects, improving the coordination and linkage mechanism of departments, and strengthening the construction of grass-roots child welfare team.

Exploring and categorising the Arabic copula and auxiliarykānathrough enhanced part-of-speech tagging

Arabic syntax has yet to be studied in detail from a corpus-based perspective. The Arabic copula kāna (‘be’), functions also as an auxiliary, creating periphrastic tense–aspect constructions; but the literature on these functions is far from exhaustive. To analyse kāna within the one-million word Corpus of Contemporary Arabic, part-of-speech tagging (using novel, targeted enhancements to a previously described program which improves the accessibility for linguistic analysis of the output of Habash et al.’s [2012] mada disambiguator for the Buckwalter Arabic morphological analyser) is applied to disambiguate copula and auxiliary at a high rate of accuracy. Concordances of both are extracted, and 10 percent samples (499 instances of copula kāna and 387 of auxiliary kāna) are analysed manually to identify surface-level grammatical patterns and meanings. This raw analysis is then systematised according to the more general patterns’ main parameters of variation; special descriptions are developed for specific, apparently fixed-form expressions (including two phraseologies which afford expression of verbal and adjectival modality). Overall, we uncover substantial new detail, not mentioned in existing grammars (e.g., the quantitative predominance of the past imperfect construction over other uses of auxiliary kāna). There exists notable potential for these corpus-based findings to inform and enhance not only grammatical descriptions but also pedagogy of Arabic as a first or second/foreign language.

A Contrastive Analysis of Carbon Emissions in Different Solutions to Battered Piles

Carbon emission from construction engineering is one of the main sources of environmental pollution. Complicated geological conditions, imperfect construction technology, and inattentive management in construction are the reasons of battered piles. The extant solutions to battered piles focus on bearing capacity, lower cost and convenience in engineering, rather than carbon emissions, as well as the requirements of environmental protection. This paper, through a contrastive analysis of carbon emissions in different solutions, concludes that the approach of prestressed pipe pile with concrete floor can significantly reduce carbon emissions to one third of its counterpart approaches. Carbon emission database for accurate calculation should be built to optimize construction projects. This paper provides a feasible solution to treat battered piles in a environment-friendly way.

Correctional labor as an alternative to imprisonment in modern problems of punishment assignment

The global practice has shown many times that the primary means of struggling with criminality over the entire history of the civilized society is punishment. The modern legislator is constantly striving to improve its types by following global trends in its regulation, assignment and use. Efficiency of labor influence over the convict makes us pay a special attention to punishments suggesting mandatory labor nurturing. One of such punishments is correctional labor whose relevance of research is caused by the interest of the international society to use measures alternative to imprisonment. Despite the fact that legal systems of some foreign countries envisage and widely use punishments whose various characteristics are similar to domestic correctional labor, the Russian experience of their regulation and use can be useful, due to their specific nature, and interesting to any modern state, because the issue of implementing a rich potential of penology is especially relevant these days. At the same time there are significant issues in assignment of correctional labor, which area caused by imperfect construction of law. Research purpose is to study urgent issues of assigning correctional labor as an alternative to imprisonment in the Russian legal system. Methods: the analysis method allowed for characterization of specific features of assigning criminal punishment in the form of correctional labor and revealing primary problems in this area. The comparative method was used to collate specifics of correctional labor and probation. The prediction method helped defining perspectives to eliminate the identified disadvantages. An alternative mode of correctional labor has been criticized; measures have been offered to improve the legislative regulation of correctional labor within Article 53.1 of the Russian Federation Criminal Code.

Research on the Characteristic Model of Survival and Development Behavior of Math Teachers in Higher Vocational Colleges Based on Big Data Technology

With the implementation of the national "double high education program", the living environment and training conditions of teachers in various disciplines have become an important field of education system reform. At present, due to the imperfect construction of teachers’ salary system and training mechanism, teachers in higher vocational colleges still face many difficulties in their survival and development, which seriously limits the implementation effect of the "double high education program". Therefore, it is particularly urgent to study the survival and development of teachers in vocational colleges. This article takes mathematics teachers in vocational colleges as the research object, and describes the current situation of the survival and development of mathematics teachers in vocational colleges. On this basis, this paper uses the refined computer big data technology to construct the survival and development behaviour characteristic model of mathematics teachers in vocational colleges, and discusses the feasible strategies to ensure the quality of survival and development of mathematics teachers, which provides a solid theoretical support for the smooth implementation of the national "double high program".

Analysis of coupling factors between high proportion wind power and ultra-high voltage DC

Due to the imperfect construction of supporting thermal power units, when wind power sources are in full swing, if DC low-power operation will inevitably lead to wind power abandonment, if DC high power operation is subject to fault transient overvoltage operation constraints, it will also cause power curtailment of wind power sources. In order to promote wind power consumption and lean management of DC influencing factors, this paper analyzes the number of supporting thermal units started, supporting unit power changed, wind power and connected substation power to find out the key factors of DC operating limit and wind power consumption. The validity of this paper was verified by a DC power grid simulation in a certain area.

Optical analogues to the equatorial Kerr\u2013Newman black hole

Optical analogues to black holes allow the investigation of general relativity in a laboratory setting. Previous works have considered analogues to Schwarzschild black holes in an isotropic coordinate system; the major drawback is that required material properties diverge at the horizon. We present the dielectric permittivity and permeability tensors that exactly reproduce the equatorial Kerr–Newman metric, as well as the gradient-index material that reproduces equatorial Kerr–Newman null geodesics. Importantly, the radial profile of the scalar refractive index is finite along all trajectories except at the point of rotation reversal for counter-rotating geodesics. Construction of these analogues is feasible with available ordinary materials. A finite-difference frequency-domain solver of Maxwell’s equations is used to simulate light trajectories around a variety of Kerr–Newman black holes. For reasonably sized experimental systems, ray tracing confirms that null geodesics can be well-approximated in the lab, even when allowing for imperfect construction and experimental error.
