Authors: Kutsayeva Alesia , Myslyva Tamara
Published: September 2020

Improving the methodology of on-farm land management in the direction of transition from the formation of work sites to the formation of management zones for the specific requirements of the agricultural producer upon implementation of precision farming is extremely important for the agricultural sector of the Belarusian economy. The article presents the results of applying the methods of geostatistical and multifactor geoinformation analysis for the formation of management zones within the limits of land use of RUE “Uchkhoz BGSHA” (Republic of Belarus, Mogilev region, Gorky district). The total area of the surveyed territory is 83420.1 hectares. The nature of the spatial distribution of data on the content of humus, mobile phosphorus and potassium in the soil as well as pH level was estimated using the tools of the Spatial Statistics module of ArcGIS version 10.5. The presence of reliable clustering of data on soil parameters was established, since the value of the global Moran index I ranged from 0.197827 to 0.360388, and the z-score in all cases exceeded 2.58. The universal kriging method turned out to be the most suitable for modeling the spatial distribution of soil pH data,
while the empirical Bayesian kriging method is the most acceptable when modeling the spatial distribution of the content of humus, phosphorus, and potassium in the soil. The method of principal components and the simple summation of rasters using a calculator proved to be suitable for identifying management zones by a set of soil parameters (the discrepancy with the actual area was 16.56 and 16.24 ha, respectively).

Authors: Puziene Ruta , Anikeniene Asta
Published: September 2020

One of the most pressing problems in land management is abandoned agricultural land. Abandoned land in Lithuania is unattended and not used for agricultural activities. These areas degrade the country's landscape and over time overgrow with shrubs or low-value plants. The article analyzes the change of abandoned agricultural land in 2015-2019. State control to reduce abandoned land is discussed. Relations with selected indicators are analyzed. Data visualization was performed with ArcGIS software. However from 2015 to 2019, a constant decrease of abandoned land has occurred. The analysis showed that the
majority of abandoned land is found in Vilnius, Utena and Alytus counties. The results of the correlation analysis showed the highest dependence of abandoned lands on the average performance score in counties.

Published: September 2020

Günümüzde endüstri paydaşları, yapı elemanlarını daha ergonomik, daha hafif ve daha sağlam malzemeler kullanarak üretme yoluna gitmektedirler. Bu durum fiber takviyeli kompozitlerin talebini arttırmıştır. Farklı çalışma koşulları altında kullanılan kompozit malzemelerin, kullanım yerlerine göre sahip olması gereken bir takım mekanik özellikler mevcuttur. Malzemenin bu mekanik davranışlarına etki eden faktörlerden biri de üretim, montaj veya kullanım sırasında meydana gelen çatlak oluşumlarıdır. Tabakalı kompozitlerin kırılma davranışlarına, deformasyon hızı, çatlak uzunluğu ve çatlak geometrisi doğrudan etki eder. Bu çalışmada, farklı uzunluk ve farklı geometride çatlağa sahip S-2 cam/epoksi tabakalı kompozitlerin farklı deformasyon hızlarındaki kırılma davranışları deneysel ve nümerik olarak incelenmiştir. Çalışma kapsamında 5mm, 10mm ve 15mm çatlak uzunluğuna ve 0º ve 45º çatlak geometrisine sahip test numunelerinin farklı deformasyon hızındaki Mod I (açılma modu) ve Mod I/II (karma mod) kırılma davranışları araştırılmıştır. Çatlak başlangıcı ile deformasyon hızı arasındaki ilişkiyi ifade etmek için kırılma testleri 8,3×10-3, 8,3×10-4 ve 8,3×10-5 s-1 olmak üzere üç farklı deformasyon hızında gerçekleştirilmiştir. Ayrıca S-2 cam / epoksi tabakalı kompozitlerin kırılma davranışları, Sonlu Elemanlar Yöntemi (SEY) kullanılarak analiz edilmiştir. Elde edilen sonuçların birbirleriyle uyumlu olduğu görülmüştür. Deneysel ve SEY sonuçları hem Mod I hem de Mod I/II çatlak ucu açma koşullarındaki S-2 cam/epoksi lamine kompozit malzemenin kırılma davranışlarının, çatlak geometrisine ve deformasyon hızına duyarlı olduğunu, ayrıca incelenen test parametrelerine göre değiştiği görülmüştür.

Authors: Silva Wesley Pereira , Oliveira Sérgio Peres de
Published: September 2020

O presente artigo é resultado de um estudo desenvolvido para a elaboração de pesquisa de conclusão do curso de Especialização em Metodologias do Ensino da Matemática da Universidade de Brasília (UnB). Tem como objetivo investigar a construção das avaliações pelos professores de Matemática que atuam com aluno com diagnóstico do Transtorno de Déficit de Atenção e/ou Hiperatividade (TDA e TDAH). A pesquisa está ancorada em uma abordagem qualitativa, do tipo estudo de caso. Utilizamos o questionário como técnica de pesquisa. Apurou-se que existem práticas de avaliação da aprendizagem de alunos com TDAH, porém de forma distante da realidade do aluno. Chegou-se à conclusão que a atuação do professor na elaboração da avaliação escolar e seu olhar diferenciado para os alunos com este transtorno é fundamental para a análise da assimilação do conteúdo de Matemática, auxiliando na superação das dificuldades que os alunos com TDAH apresentam. Além disso, constatamos que em muitas situações as provas de Matemática são adaptadas para os estudantes com TDAH, mas o professor utiliza critérios específicos para a correção dessas avaliações.

Published: September 2020

O objetivo deste artigo é apresentar parte da pesquisa amostral intitulada “Análise de Práticas Pedagógicas e avaliativas:  contribuições para a política de Formação Docente” realizada no ano de 2017, em 04 salas de aula de 5ºs anos, de 04 escolas com bons resultados no IDEB, no município de Macaé-RJ. Deu-se a partir de um olhar apurado sobre a metodologia dos professores em sala de aula e suas práticas avaliativas. A metodologia da pesquisa foi de cunho Qualitativo Bibliográfica e de campo através de observações e aplicação de questionários. A pesquisa contou com a participação de 08 alunos/pesquisadores da licenciatura em Matemática da Faculdade Professor Miguel Ângelo da Silva Santos – FeMASS. O tema da investigação justifica-se, na defesa da ideia de que a atuação do professor em sala de aula é um dos elementos que deve ser considerado ao olhar-se o desempenho da escola. Como fundamentação teórica utilizou-se os conceitos de campo e de habitus, postos por Pierre Bourdieu (2003, 2009) e outros autores que discutem a avaliação. Os resultados mostraram que o lugar ocupado pela avaliação não é igual em todas as escolas, alguns professores valorizam a heterogeneidade da sala de aula e subjetividade dos alunos, enquanto outros dão centralidade ao treinamento para as avaliações externas. Considerou-se que se precisa ouvir os professores acerca de suas necessidades cotidianas, a fim de se pensar junto de que maneira a formação continuada pode auxiliar mais efetivamente na resolução dos problemas inerentes à sala de aula.

Caminhos do desenvolvimento profissional docente na perspectiva freireana
Authors: Cruz Lilian Moreira , Barreto Andreia Cristina Freitas , Ferreira Lúcia Gracia
Published: September 2020

O presente artigo objetiva discutir possibilidades de caminhos do Desenvolvimento Profissional Docente (DPD) na perspectiva freireana, tendo como aporte o livro “Medo e ousadia: o cotidiano do professor”. Paulo Freire é tomado neste estudo como possibilidade de rompimento paradigmático que, na atualidade, é oportuno, sobretudo, no Brasil, país que atravessa um momento de severas críticas sobre os profissionais da educação, pois estes vêm sofrendo retaliações em sua autonomia, formação e prática docente, o que, consequentemente, vem provocando, muitas vezes, rupturas no DPD. Diante desses desafios vividos pelos/as professores/as, se faz necessário reinventar o pensamento de Paulo Freire para provocar problematizações e reflexões sobre os possíveis caminhos para Desenvolvimento Profissional Docente. Desse modo, fizemos uma revisão do livro citado, apontando possibilidades de contribuições da perspectiva freiriana para o DPD, a partir da formação, do currículo, do ensino e da relação do professor/a com o conhecimento. Com isso, constatamos que Freire muito contribuiu para os estudos sobre o DPD, apontando possíveis caminhos para a evolução e continuidade desse processo.

Published: September 2020

This review paper looks at the causes of welding defects and their remedies which occur during the welding process. Welding industries in developing countries bearing poor quality and productivity due to the involvement of a number of the process parameter. Even in a completely controlled process, defects in the welding are observed and hence welding process is also known as the process of uncertainty which challenges explanation about the cause of welding defects. In order to identify the welding defect and problem-related to welding, the study is aimed at the research work. This will be beneficial in enhancing the yield of welding. Beside this, standardization (optimization) of process parameter for the entire cycle of manufacturing of the critical part is intended in the proposed work .This review paper also provides the accurate guideline to the quality control department to find welding defects and will help them to analyze defects which are not desired. In this review paper, an attempt has been made to categorise the various welding defects and their root causes of happening.

The continuously changing and developing technology framework and IT infrastructure create novel approaches and possibilities all over the industry spectrum. Thus the energy and its IT supporting segment cannot be an exception either. Nowadays it is hard to imagine any kind of work process on energy generation, transmission, distribution or consumption filed without IT application solutions. To keep this portfolio transparent and effective a methodology is needed for developments and strategy planning. In this paper enterprise application landscape planning experiences and recommendations are introduced. The approach effectively combines the TOGAF (The Open Group Architecture Framework) and Agile methods. At the end of a five years ‘journey’, the evolution can be followed from a target architecture planning approach to a novel solution which is in use right now. To conclude this work a group of techniques and methods are suggested for the application of these solutions for a sustainable and forward-looking application portfolio at a reasonable cost level.
Grid Fault Ride Through Capability of Voltage Controlled Inverters for Photovoltaic Applications
Authors: Islam Abdelraouf  , Sobhy Abdelkader  , Mohamed Saeed
Published: September 2020

Fault ride through (FRT) capability is one of the challenges faced in today's large-scale grid photovoltaic (PV) power system.
Solar  PV  systems  are  designed  to  disconnect,  and remain offline  for  5  mints  when  tripped  by  loss  of  grid  voltage. However, The  PV  system,  by  itself,  cannot  differentiate between   transient   and   sustained   grid   voltage   loss.   It behaves   in   the   same   manner   in   the   two   cases,   i.e., disconnect, stay offline for five minutes and then makes re-connection    trial.    Staying    offline    for fiveminutes unnecessarily  wastes  considerable  amount  of  clean  energy from the PV, may affect the power balance of the grid and many other adverse effects of service discontinuity.
This paper presents a new control strategy for grid FRT capability of a large grid connected PV System  to increase the stability and reliability of the PV system, in which a photovoltaic inverter can be controlled to pass transient faults. Our strategy is to control the inverter  so  that  it  disconnects  from  the  grid  when  the  current exceeds  a  specific  value  for  a  specific  time  otherwise,  it  still connected and ride-through the faults to ensure continuous output power under transient fault conditions. A case study of a 100 KW PV  power  system  simulated  to  ensure  the  proposed  control.  The results show the ability of the proposed control method to manage various types of grid faults. A case study of a 100 KW PV power system simulated to ensure the proposed control. The results show the  ability  of  the  proposed  control  method  to  manage  various types of grid faults.

Published: September 2020

Distributed Generation (DG) in Spain has recently been boosted through the impact in the regulatory framework of the electrical grid and the electrical market provided by the Royal Decree 244/2019. One important novelty is that it incorporates to the Royal Decree 842/2002 a modification establishing that prosumers associated to a self-consumption Grid-connected Microgrid (GCMG) classified as without energy surplus, cannot deliver energy to the electrical network. The criteria for ensuring this restriction only consider classical Power Factor (PF) calculation, Overvoltage and DC current injection and do not consider Power Quality (PQ) issues related to Total Harmonic Distortion (THD). In the recent years, nonlinear loads are increasing its presence in the electrical installations consumption side. Nonlinear loads such as lighting, electronic devices and others can pollute with harmonics the GCMG and, therefore, the Grid. This work proposes an assessment of the modifications of the Royal Decree 842/2002 considering PQ issues related to THD due to the Nonlinear Loads existing on a GCMG in the context of the Smart Grid (SG).

Managing letters related to residence in Babau Village usually takes a long time. Residents must meet directly with the head of the RT/RW in the domicile area to obtain a cover letter, then they can go to the Kelurahan office to arrange the intended documents. The problem that then arises is if the community cannot meet the RT/RW leader because of busy life. Likewise if it arrives at the Kelurahan office, it turns out that the Lurah is not there. This will certainly hinder the management process. In addition to the above problems, another problem that can also arise is the RT/RW cover letter that has the potential to be falsified.These problems can be solved by building a Digital Village platform where the community does not need to meet directly with the RT/RW but can use the existing platform to manage the required documents. The proposal letter that goes to RT/RW can be directly approved and forwarded to the Village Head to be approved and ready to be printed. Everything is done without the need for paperless paperwork.
