Prolonged Response Time Concealed Information Test decreases probe-control differences but increases classification accuracy
Authors: Lukács Gáspár
Published: August 2021

The Response Time Concealed Information Test (RT-CIT) can reveal that a person recognizes a relevant item (probe, e.g. a murder weapon) among other, irrelevant items (controls), based on slower responses to the probe compared to the controls. The present paper assesses the influence of test length (due to practice, habituation, or fatigue) on two key variables in the RT-CIT: (a) probe-control differences and (b) classification accuracy, through a meta-analysis (using 12 previous experiments), as well as with two new experiments. It is consistently demonstrated that increased test length decreases probe-control differences but increases classification accuracies. The main implication for real-life application is that using altogether at least around 600 trials is optimal for the RT-CIT.
Welfare and Competition in Expert Advice Markets
Authors: Albertazzi Andrea , Ploner Matteo , Vaccari Federico
Published: August 2021

We perform a controlled experiment to study the welfare effects of competition within a strategic communication environment. Two equally informed senders with conflicting interests can misreport information at a cost. We compare a treatment where only one sender communicates to a treatment where both senders privately communicate with a decision-maker, all else equal. Data show that competition fails to improve decision-making and harms senders' welfare. As a result, the overall market welfare is significantly lower under competition. In both treatments, senders reveal less information, and decision-makers obtain less than the most informative equilibria predict. However, they still reveal and get more information compared to other equilibria.
Numerical solution of a fractal-fractional order chaotic circuit system
Authors: Altaf Khan Muhammad , Atangana Abdon , Muhammad Taseer , Alzahrani Ebraheem
Published: August 2021

The dynamical system has an important research area and due to its wide applications many researchers and scientists working to develop new model and techniques for their solution. We present in this work the dynamics of a chaotic model in the presence of newly introduced fractal-fractional operators. The model is formulated initially in ordinary differential equations and then we utilize the fractal-fractional (FF) in power law, exponential and Mittag-Leffler to generalize the model. For each fractal-fractional order model, we briefly study its numerical solution via the numerical algorithm. We present some graphical results with arbitrary order of fractal and fractional orders, and present that these operators provide different chaotic attractors for different fractal and fractional order values. The graphical results demonstrate the effectiveness of the fractal-fractional operators.

Steady flow of high-paraffin bituminous binder in cylindrical tube in terms of Herschel – Bulkley fluid
Authors: Matvienko Oleg V. , Litvinova Alyona E.
Published: August 2021

This paper deals with the flow of bitumen binder in a cylindrical tube described by the Hershel-Bulkley fluid. The dependence is suggested for the fluid flow rate and the pressure drop. Dependences are also determined for the radial velocity distribution and effective viscosity. It is found that at a low pressure drop, the non-Newtonian properties of the medium lead to a significant hydraulic resistance due to the internal structure. With an increase in the pressure drop, the hydraulic resistance of the flow decreases.

Authors: Tru Nguyen Anh , Huu Cuong Tran , Huyen Vu Ngoc
Published: August 2021

The aim of this article is to assess the importance and development of high-tech agriculture in Vietnam under the context of industrialization and urbanization. Due to pressure from international economic integration and climate change in recent years, high-tech agriculture seems to be an affordable direction for Vietnam to renovate the agricultural sector. Although high-tech agriculture has existed in different locals and sub-sectors of agriculture such as crop, livestock, and aquaculture, and Vietnam has obtained initial achievements in adopting high-tech agriculture, this country has to face a number of challenges related to land, credit, information technology, and human resources in the process of developing high-tech agriculture. Lastly, policies are recommended to facilitate the development of high-tech agriculture in Vietnam.

Published: August 2021

Situated in the Northern Mountain Region, one of the most climate-vulnerable regions of Vietnam, Yen Bai province is exposed to many climate risks. This study investigated how well Yen Bai farmers were aware of the impacts of the changing climate on production and their livelihoods and how they referred support programs from the central and local governments to make decisions on adaptation and resilience strategies. Data were collected through direct interviews of 488 cassava households in six communes of Van Yen district. Descriptive statistics, One-way ANOVA, and Chi-square test were used to statistically analyze the data. In addition, we employed the Partial Least Square Structural Equation Modelling (PLS-SEM) to study the relationships of three identified independent variables: (i) understanding of support programs/policies; (ii) access to weather information; and (iii) experience of climate risks and impacts, and farmers’ perceptions of climate impacts. Results from the PLS-SEM model showed that farmers with higher positive scores in the three independent variables above had better perceptions of climate change and its possible impacts, from which better adaptation decisions and strategies could be derived. These research findings emphasized the need for improving the understanding of climate change that could impact farmers’ livelihoods, farmers’ access to accurate near-time and medium-term weather forecasts, and thoroughly using local knowledge on climate risks and effective native adaptation measures for better adaptation and mitigation strategies and actions in rural climate-vulnerable communities in Vietnam.

Published: August 2021

This study was conducted to examine general information of tax obligations and perceived tax compliance for small and medium enterprises in the district of Gia Lam district. To achieve these objectives, 150 small and medium enterprises were randomly selected and analyzed using descriptive analysis and Principal Component Analysis (PCA). The results show that most of enterprises got difficulties in register, declare and pay taxes, and nearly half of them had submitted taxes lately. Besides, perceived tax compliance of enterprises could be divided into five key factors, including: "Quality of tax services"; "society norms"; "Technology Application"; "Enterprise responsibility "; and "Quality of tax officials". Based on these results, some recommendations could give to the tax authorities in order to improve tax regulations and policies.

Published: August 2021

Mineral nutrients are essential to plant growth and development. The present study aimed to evaluate the effects of mineral fertilizer doses and N:P:K ratio on growth, yield, and raw material quality of the tea variety PH10 to improve the production of high-quality tea products. The field experiment was conducted from 2015 to 2017. A two-factor experiment was designed by split-plot design with three replications. The mainplot treatments were three fertilizer doses of N  for one metric ton of fresh shoot products (30, 40, and 50 kg N ha-1). The subplot treatments were two NPK ratios (3:1:1 and 3:1:2). Plant height, leaf canopy, plant diameter, shoot yield parameters, shoot components, biochemical compounds, and sensory quality for Oolong and Sencha tea products were evaluated. The results showed that increasing fertilizer doses from 30 up to 40 kg N per ton of fresh product improved remarkably growth, yield, and tea quality of PH10 variety. Different fertilizer ratios resulted in variations in plant growth, the content of carbohydrate, sensory quality for taste and flavor as well as total sensory quality with higher values at NPK ratio of 3:1:2. Applying mineral fertilizer with an NPK ratio of 3:1:2 and 40kg N per ton of fresh shoot products was recommended to bring about the most benefits of tea yield and quality as well as economic profit.

Authors: Thu Thieu Thi Phong , Thiem Tran Thi , Loan Nguyen Thi , An Pham Van
Published: August 2021

This study was conducted to examine the effects of baby corn density on the crop and weed performance under two different maize-soybean intercropping systems. Treatments included four baby corn densities (D1= 138,888 plants ha-1, D2 = 111,111 plants ha-1, D3 = 92,592 plants ha-1, and D4 = 79,365 plants ha-1), and three intercropping methods (P0 = a sole cropping of baby corn, P1 = 1 row of soybean + 1 row of baby corn (density of soybean, 10 plant m-2), and P2 = 2 rows of soybean + 1 row of baby corn (density of soybean, 20 plants m-2)). Physiological characteristics and yield were measured for the baby corn and soybean. The weed species, weed frequency, and the growth of the weeds were recorded at the final harvesting time of the baby corn. The results showed that the yield of soybean and the growth of the weeds were statistically different under the different maize-soybean intercropping systems. Increasing the baby corn density increased the leaf area index, dry matter accumulation, and cob yield, but did not have a clear effect on the soybean yield under both intercropping methods. In addition, the P2 intercropping method produced significantly higher soybean yield and gave better results of weed growth reduction in comparison with the P1 intercropping method. In the P2 intercropping method, baby corn should be grown at a density of 111,111 plants ha-1 to optimize the population productivity and achieve reasonable weed control for the sustainability of agriculture.

Authors: Loan Nguyen Thi , Can Tran Thi My
Published: August 2021

To study the effects of cover methods and nitrogen (N) levels on the growth and yield components of tomato Cv. Pear F1, field experiments with a 4x3 factorial design were conducted in the 2019 spring and winter seasons using a randomized complete block design with three replications. The cover methods included four treatments: bare soil (BS), black plastic mulch (BPM), transparent polypropylene row cover (RC), and a combination of BPM and RC (BPMRC) with the RC removed approximately 30 days after transplanting. Nitrogen (N) was applied at three levels (150, 180, and 210 kg N ha-1). Using BPM and RC generally led to an increased air temperature, air humidity, soil moisture, and soil temperature compared to the BS treatment. Higher N rates (180 and 210 kg N ha-1) did not result  in different tomato fruit sizes and fruit weights but positively increased fruit yield and quality (Brix values and fruit dry weight) as compared to the 150 kg N ha-1 addition. The cover methods positively affected the yield components and fruit yield of tomato as well as the fruit characteristics compared to the BS treatment. Using cover materials (BPM and RC) combined with a higher N application significantly increased the yield attributes and fruit yield. The highest fruit yield was achieved under the mulching treatment by black plastic (BPM treatment) combined with a 210 kg N ha-1 application, resulting in 50.90 tons ha-1 in the spring and 58.27 tons ha-1 in the winter.

Authors: Linh Nguyen Thi , Cham Le Thi Tuyet , Thang Vu Ngoc
Published: August 2021

This study was conducted to evaluate the salt tolerance ability of two soybean cultivars under salinity conditions using a selection of growth and physiological parameters. Three weeks after germination, plants began being treated with either a 100 mM concentration of NaCl in Hoagland solution or a non-salinity (0 mM NaCl) solution. The results showed that the plant height, number of leaves, leaf area index, and shoot and root biomasses were significantly reduced under salt conditions. A similar tendency was observed in several physiological parameters (SPAD, Fv/Fm). Since all the salt-treated plants of the D8 cultivar were dead after 40 days under the 100 mM NaCl treatment, the yield of D8 could not be obtained, while the treated plants of the D140 cultivar experienced a marked decrease in yield compared to the control plants. In this study, we identified that the D140 soybean cultivar had a better salt tolerance than the D8 soybean cultivar at a 100 mM NaCl concentration.
Russia-Africa Business Dialogue at SPIEF 2021: Trends, Problems and Prospects for Russian-African Cooperation
Authors: Abramova Irina
Published: August 2021

More than a year and a half has passed since the first Summit and the Russia-Africa Economic Forum. The crisis of “Western-style” globalization, accelerated by the coronavirus pandemic, has adjusted the formation of the Russian business strategy in the African direction. The most important areas of Russian-African cooperation in the near future are healthcare, ensuring food security, infrastructure projects, including digitalization, education and science. With what results will Russia and Africa approach the next Summit, planned for 2022? Which business strategy will meet both Russian and African interests? What Russian investment projects are already being implemented on the African continent? How are the new mechanism and tools of the Russian-African partnership formed? These and other issues on the Russian-African agenda were discussed at the Russia-Africa business dialogue, which was held on June 3, 2021 as part of the St. Petersburg International Economic Forum. This was the first major Russian African event in full-time format after the historic Russia-Africa Summit and Economic Forum, which was successfully held in Sochi on October 23-24, 2019.
The participants in the discussion concluded that Africa needs Russia to achieve the ambitious goals of the Agenda 2063, but Russia also needs Africa to implement the new development strategy of the Russian Federation, which focuses on increasing non-resource exports and technological breakthrough. The African fast-growing market, formed by the youngest population in the world, is showing an increased demand for modern Russian goods and technologies, primarily in such areas as healthcare, agriculture, infrastructure, resource development, and digital products.
To intensify cooperation, it is necessary to use the entire set of instruments of public-private partnership, to utilize the information resource at full capacity, and to develop cooperation in the field of science and education. The main thing for us now is to bring our cooperation, including in the economic sphere, to a fundamentally new level that meets the interests of our peoples. Both Russia and Africa have a lot to learn from each other, and our economic strategies can be successfully implemented if we combine our efforts.
Religious factor in the political process in Zambia: mutual influence of religion and politics
Authors: Prokopenko Liubov
Published: August 2021

The article examines the problem of growing politicization in some religious confessions, primarily Christianity, in the process of democratization that began in Zambia in the early 1990s. Zambia is one of the African countries whose religious leaders have played a prominent role in social life throughout their history. It is especially noted that the proclamation of Zambia a Christian nation in 1991 by President Frederick Chiluba contributed greatly to the strengthening of mutual influence between politics and religion.
In modern Zambia religious organizations adhere generally to neutrality, the liberal part of all confessional groups seeing their task in solving primary social problems. In recent decades there have been no pronounced ethnic and religious contradictions in the country which could contribute to an emergence of open bloody conflicts threatening internal security and stability.
The article shows that with Edgar Lungu’s (Patriotic Front, PF) coming to power in 2015, Zambia was proclaimed a Christian nation again, which was enshrined in the new edition of its Constitution. The campaigns for presidential elections in 2015 and for general elec-tions in 2016 have shown that “religion-politics” discourse has become relevant in the political process, regarding primarily multiple rela-tionships between religion, ethnicity and politics. The country is on the eve of new general elections due in August 2021. In a difficult economic situation, exacerbated by the COVID-19 pandemics, Zambian government and Church officials are calling on voters to ensure peaceful electoral process.
Riyadh changes priorities - “smart” cities and resorts instead of oil?
Authors: Dudarev Konstantin P.
Published: August 2021

The article examines the progress of the implementation of socio-economic reforms, which began in 2016 after the promulgation of the new "Strategy of the Kingdom of Saudi Arabia" called "Vision 2030", and aimed at diversification of the economy and modernization of the country. The focus is on two main areas of economic development - tourism and the construction of "smart" cities of the future. 
In accordance with the logic of the new strategy the economic geography of the Kingdom is also changing. If in the previous decades the state's efforts and investments were directed mainly to the east of the country, on the coast of the Persian/Arabian Gulf, where oil de-posits are concentrated, today, during the transition to the post-oil era, the main attention is paid to unlocking the potential of the western regions adjacent to the coast of the Red Sea. 
In brief, the result of 5 years of reforms is that the words "post-oil era" have ceased to be an abstract concept. As an evidence of the population's support for the reforms, the author cites the results of a survey by UN staff members of the Kingdom's residents, most of whom expressed satisfaction with the quality of life and the actions of the authorities, as well as the report of the IMF mission, which praised the activities of the KSA government on tourism and the entertainment industry development, to combat the pandemic, and to in-crease the role of the private sector in the country's economic development.
At the same time, the author believes that despite the obvious successes, it would be a delusion to believe that all the risks associated with the implementation of reforms have been left behind.
Dynamic Response Characteristics of Aeolian Sediment along Sichuan-Tibet Railway
Authors: Han Kan , Xue Chunxiao
Published: August 2021

In order to reduce the damage of liquefaction of aeolian sand along the Sichuan-Tibet railway, the dynamic response characteristics of saturated aeolian sand in the study area were discussed by using shaking table test. The results show that the macroscopic characteristics of saturated aeolian sand in the study area are subsidence, water flow and fracture. The displacement time history shows that the surface displacement increases with increasing the input ground motion acceleration. When the acceleration is small (0.1g), the vibration in the soil layer has an obvious tendency to enlarge continuously from bottom to top. With the increase of the acceleration (0.2g), the amplification trend basically disappeared. When the acceleration increases to 0.3g, the ground motion increases first and then decreases.
The Importance of Liberal Arts in the Digital Age
Authors: Zhang Yan
Published: August 2021

Liberal arts are vulnerable to the challenge that they are useless in the digital age. “Uselessness is a kind of usefulness” — that is, although liberal arts fail to mold the practical skills, for example, the skills that enable people to earn much money in markets, they are useful in other senses, which is a common and seemingly philosophical answer to the question about the function of liberal arts. Such an answer, however, seems insufficient and abstract. In this article, the author intends to demonstrate with examples and statistics that liberal arts play an irreplaceable role in nursing people’s critical thinking, expanding their imagination and understanding of the differences of the world. Moreover, technology is essentially related to the understanding of human society. User-friendly technology is the combination of empathy and the understanding of humanity.

Published: August 2021

International students have contributed to the internationalization and diversification of U.S. higher education; yet, when COVID-19 (i.e., coronavirus) struck, it became evident that this subset of the U.S. higher education student population was left unaccounted for and unprotected. This manuscript underscores the unimaginable damage and disruption that can occur when a global crisis of the highest magnitude meets under preparedness, pre-existing discrimination, and impulsive policy-making. It also highlights, for context, past crises and their impacts on international students, thus establishing a trend which places international students at the epicenter of the blow’s concomitant with crises of different nature. Moreover, the manuscript provides considerations higher education stakeholders should reflect upon, as well as the following implications for higher education institutions: a) Establish support systems, b) create a sustainable emergency/crisis relief fund, c) seek and maintain non-local partnerships, d) get in good trouble, and e) develop intervention programs. In enacting these tangible solutions, institutions would be able to guide, serve, and support international students more effectively during and after crises.

Published: August 2021

The COVID-19 pandemic has undoubtedly exacerbated the challenging situation facing many students in colleges and universities in the United States. To promote student success and address equity issues in higher education, there is an urgent need to treat students as humans first and attend to their basic needs. In this essay, I present evidence pointing to the fact that the pandemic has made student basic needs insecurity even worse. However, well designed and successfully implemented emergency aid programs and other innovative interventions with equity at the center can help address problems in student basic needs insecurity. I present successful examples in addressing student basic needs insecurity and call for sustained and bold actions.

Human Trafficking in Woman and Children Perspective; Protocol to Prevent, Suppress and Punish in Persons
Authors: Aryana I Wayan Putu Sucana
Published: August 2021

Trafficking in persons is a cross-border crime which injures human dignity. The mode of trafficking in persons is to take advantage of the economic conditions of potential victims by luring them a better job. This research will discuss the profile of victims of trafficking in persons, gender analysis in human trafficking, and international policies in victim protection that are gender equality oriented. This research is a normative juridical study examining the analysis of international legal instruments, laws and court decisions. The research was conducted using the statute approach, legal concepts and the concept of gender. The victims of trafficking in persons are dominated by women, although it does not rule out the possibility that men can also be the victims. Women are considered as commodities that can provide benefits because they can be bought and sold to do work without requiring high education, and even provide sexual services. The perpetrators of the criminal network carry out the recruitment of potential victims by involving the householder of the potential victim, in this case the husband or father of the potential victim. This condition cannot be separated from the deep rooted patriarchal culture in the society, in which the men play a role as the decision makers in the family. Power relations play an important role in analyzing this crime of trafficking in persons. Efforts to combat trafficking in persons are carried out within the framework of a gender-equitable policy. However, the existing legal instruments have not addressed the fundamental problems of trafficking in women. Reconstruction of the legal culture of society is very important in protecting women from various forms of violence.

In pre-school age, children generally show significant development, especially in aspects of cognitive development.This happens because in pre-school age is a golden age that is often called golden age.Cognitive development is not necessarily able to take place optimally without the stimulus or stimulation given to pre-school age children.Lack of stimulation given to pre-school age children can result in loss of brain cells function so that it will impact the slow cognitive development and impact on the child's ability to process the information received.The research method in this study is to use literature studies based on the results of analysis of the results of research used as literature in this study.The procedure in conducting literature studies in this study is to determine the formulation of problems, find relevant literature, evaluate the data obtained, analyze and then interpret the data that has been obtained.Based on the study of literature can be obtained the conclusion that the provision of stimulation education in pre-school age children can improve the cognitive development of pre-school age children
Integrated Weed Management Strategies for Sustainable Rice Production in Bangladesh
Authors: Bhuiyan MKA , Salam MU , Kabir MS
Published: August 2021

Weed causes huge reduction in crops yield, increases cost of cultivation, reduces input efficiency, interferes with agricultural operations, impairs quality, act as alternate hosts for several insect and diseases .Yield loss due to improper weeding at farmer’s field ranged from 4 to 22% depending on different rice ecosystem in Bangladesh. But at present considering all the cultivable land across the country and other issues; yield loss due to weeds considered about 2% in a consultation meeting.The present weed control practices in Bangladesh are characterized by intensive use of manual labour, use of herbicide and certain mechanical weeding. Manual weeding, besides laborious is inefficient as it is not done in time in most of the cases and always not practical because of various adverse conditions. Cost effective and integrated weed management system should be adopted to increase economic gain and sustainable rice production. Adopting timely and effectively appropriate weed management techniques we can reduce a significant amount of yield loss and about 0.43 million ton (MT) additional yield could be increased by 2030. To achieve the target weed management should be done from the very beginning of rice production and up to 30-35 DAP (days after planting) for Aus season, 35-40 DAT (days after transplanting) for T. Aman season and 40-45 DAT for Boro season which indicates critical period of weed infestation in Aus, T. Aman and Boro season. The main approach is that rice field have to keep free from weed up to that days by 2/3 hand weeding (HW) or application of herbicide fb (Followed by) 1HW or applying weeder fb 1HW which is called integrated weed management. Herbicide should be applied at proper time and dose which reduce 61% weeding cost. Mechanical weeding (MW) reduces 50% weeding cost that keeps environment friendly. Future weed science research specially herbicide efficacy with correct time and dose, new molecule herbicide with low environmental effect, herbicide residues in soil plant system, bioherbicide, allelopathic variety, weed competetive variety, mechanical weeder with related technological developments need a multidimensional approach for ecologically sustainable integrated weed management. Such a system will work toward a socially permissible, environmentally sound, economically feasible, productive and sustainable agricultural system.

Published: August 2021

Perilymph fistula (PLF) is defined as an abnormal communication between the middle ear cavity and perilymphatic space of the inner ear. Most cases of PLF are responsible for pressure change caused by internal trauma or external trauma. However, spontaneous PLF might occur without an obvious history of barotrauma. We report two cases of possible spontaneous PLF in the postpartum period: both cases involved progressive sensorineural hearing loss with positional dizziness. Although the leakage of perilymph was not found during exploration, both hearing loss and dizziness improved immediately after PLF repair. It is necessary to consider the possibility of PLF in patients who have sudden or progressive sensorineural hearing loss with positional nystagmus. Early surgical exploration is recommended even if the history of barotrauma is not clear.

Background and Objectives The purpose of this study is to compare diagnostic outcome and safety of fine needle aspiration (FNA) and core needle biopsy (CNB) in patients with cervical lymphadenopathy. Subjects and Method This retrospective studies were conducted on 164 cases with cervical lymphadenopathy that had undergone FNA, and 44 cases that had undergone CNB. The cytopathological results from FNA and CNB were compared with the histopathological results confirmed by excisional biopsy in the nodes according to different sizes and radiological levels, respectively. Diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were evaluated according to disease entities.Results FNA is more accurate than CNB in most of the sizes and at all cervical levels. However, there is no statistically significant difference between the results of the two tests. Sensitivity and NPV for diagnosis of malignant lymphoma are higher with FNA than with CNB. However, specificity and PPV for malignant lymphoma are higher with CNB than with FNA. Also CNB showed superior sensitivity, PPV and NPV for metastatic lymphadenopathy. Conclusion Although CNB is beneficial in reducing the false negative rate, it still has several limitations. Since CNB has no statistically significant advantage over FNA, FNA can be a good alternative method with less complication and high diagnostic value for lesions where CNB is difficult to perform.

Pharyngocutaneous fistula is a readily encountered complication that occurs after surgery for laryngopharyngeal cancer. The development of pharyngocutaneous fistula increases hospitalization, delays postoperative adjuvant treatment, and can lead to serious complications such as wound infection and carotid artery rupture. Transoral robotic surgery (TORS) is actively being performed as a standard procedure for surgery of pharyngeal and laryngeal cancers. Many reports verified that TORS is advantageous in terms of perioperative outcomes such as decreased hospitalization and reduced rate of postoperative complications, free flap reconstruction, and tracheostomy or gastrostomy tube dependence relative to open surgery. However, careful selection of patients is mandatory and there are some critical points to consider in optimal treatment outcomes. Recently, we experienced a 47-year-old patient with tonsillar cancer who underwent lateral oropharyngectomy by TORS and radical neck dissection. Unfortunately, multiple pharyngocutaneous fistulae occurred following postoperative concurrent chemoradiotherapy (CCRT). Multiple phrayngocutaneous fistulae following TORS and postoperative CCRT have not been reported in the literature. Therefore, we report this case with a brief discussion supported by a review of the relevant literature.

Published: August 2021

This paper aims to respond to these concerns
through the identification and explanation of the most
popular and effective NDT approaches in concrete
structures and also their accuracies. The fundamentals of
the non-destructive test methods are discussed in terms of
their capacity, limits, inspection techniques and
interpretations. Factors that affect the performance of NDT
an approach are discussed and means of mediate their
influence was suggested. Ultrasonic pulse velocity and
SONREB methods of Non-destructive test are showed in
this paper as past experiments of NDT. NDT of concrete
was found to be increasingly recognized as a way of
measuring the strength, integrity, resilience and other
properties of existing concrete structures, Perceptions of
NDT inadequacy are attributed to lack of knowledge of the
building materials and the NDT approaches themselves.
The goal of this paper is to resolve these issues reviewing
some articles already done and defining and discussing the
most common popular NDT methods applied to concrete
structures.

Published: August 2021

Medium-and long-term load forecasting in the distribution network has important guiding significance for overload warning of distribution transformer, transformation of distribution network and other scenarios. However, there are many constraints in the forecasting process. For example, there are many predict objects, the data sample size of a single predict object is small, and the long term load trend is not obvious. The forecasting method based on neural network is difficult to model due to lack of data, and the forecasting method based on time sequence law commonly used in engineering is highly subjective, which is not effective. Aiming at the above problems, this paper takes distribution transformer as the research object and proposes a medium-and long-term load forecasting method for group objects based on Image Representation Learning (IRL). Firstly, the data of distribution transformer is preprocessed in order to restore the load variation in natural state. And then, the load forecasting process is decoupled into two parts: the load trend forecasting of the next year and numerical forecasting of the load change rate. Secondly, the load images covering annual and inter-annual data change information are constructed. Meanwhile, an Image Representation Learning forecasting model based on convolutional neural network, which will use to predict the load development trend, is obtained by using load images for training; And according to the data shape, the group classification of the data in different periods are carried out to train the corresponding group objects forecasting model of each group. Based on the forecasting data and the load trend forecasting result, the group forecasting model corresponding to the forecasting data can be selected to realize the numerical forecasting of load change rate. Due to the large number of predict objects, this paper introduces the evaluation index of group forecasting to measure the forecasting effect of different methods. Finally, the experimental results show that, compared with the existing distribution transformer forecasting methods, the method proposed in this paper has a better overall forecasting effect, and provides a new idea and solution for the medium-and long-term intelligent load forecasting of the distribution network.
