A Comparative Simulation Study of the Thermal Performances of the Building Envelope Wall Materials in the Tropics
Authors: Jannat Nusrat , Hussien Aseel , Abdullah Badr , Cotgrave Alison
Published: June 2020

The building walls which form the major part of the building envelope thermally interact with the changing surrounding environment throughout the day influencing the indoor thermal comfort of the space. This paper aims at assessing in detail the different aspects (thermophysical properties, thickness, exposure to solar heat gain, etc.) of opaque building wall materials affecting the indoor thermal environment and energy efficiency of the buildings in tropical climate (in the summer and winter days) by conducting simplified simulation analysis using the Integrated Environmental Solutions Virtual Environment (IES-VE) program. Besides, the thermal efficiency of a number of selected wall materials with different thermal properties and wall configurations was analysed to determine the most optimal option for the studied climate. This study first developed the conditions for parametric simulation analysis and then addressed selected findings by comparing the thermal responses of the materials to moderate outdoor temperature and energy-saving potential. While energy consumption estimation for a complete operational building is a complex method by which the performance of the wall materials cannot be properly defined, as a result, this simplistic simulation approach can guide the designers to preliminary analyse the different building wall materials in order to select the best thermal efficiency solution.
Exploring Access to Nature Play in Urban Parks: Resilience, Sustainability, and Early Childhood
Authors: Beery Thomas
Published: June 2020

Nature play is an important component of the development of resilience in early childhood. Nature play is also an element of urban sustainability through a consideration of access to urban nature. From the foundation of access to nature play as a part of both resilience and sustainability considerations, a mixed-method case study was initiated. Spatial analysis, survey outreach, and focus group methodology have been combined to consider whether city parkland provides access for preschools to incorporate nature play, and, further, whether other barriers may exist to limit or prevent the use of city parks for nature play by preschool programs. The results indicate the existence of quality proximate access, but other factors creating barriers for broader application of nature play exist. The results also illustrate the critical role of public access to public parks as part of urban sustainability and the development of resilience in young children. The implications for the use of city parkland for nature play are presented.

Authors: Tamadon Abbas , Baghestani Arvand , Bajgholi Mohammad
Published: June 2020

The effect of various tungsten carbide (WC) pin tools and operating parameters on the material structure and properties of an AA1100 friction stir welding (FSW) weld were evaluated. Three different pin shapes were employed (conical, square and threaded). For each tool shape, welds were generated for a set of tool (revolutions per minute, RPM) (710, 1120 and 1400) and advancing speeds (150, 250 and 400 mm/min). Weld samples were tested for mechanical strength by tensile testing. Morphology was examined using optical microscopy, and weld composition with scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). No weld contamination from the tools was observed. However, a number of structural defects, inherent to the FSW process, were observed (including tunnel voids, kissing bonds and swirling lines). These defects, associated with the stirring action, could not be eliminated. The results show how the operating parameters may be optimized to produce stronger welds.

Published: June 2020

Next-generation sequencing (NGS) in HIV drug resistance (HIVDR) testing has the potential to improve both clinical and public health settings, however it challenges the normal operations of quality management systems to be more flexible due to its complexity, massive data generation, and rapidly evolving protocols. While guidelines for quality management in NGS data have previously been outlined, little guidance has been implemented for NGS-based HIVDR testing. This document summarizes quality control procedures for NGS-based HIVDR testing laboratories using a laboratory information systems (LIS) framework. Here, we focus in particular on the quality control measures applied on the final sequencing product aligned with the recommendations from the World Health Organization HIV Drug Resistance Laboratory Network.

Published: June 2020

Domain III of the envelope protein (EDIII) is the major target of flavivirus neutralizing antibody. To date, little is known regarding antibody-mediated neutralization of Tembusu virus (TMUV), a novel flavivirus emerging in duck in 2010. Here, a novel monoclonal antibody (MAb), designated 12F11, was prepared by immunization of mice with recombinant EDIII (rEDIII) protein. Using virus neutralization test, 12F11 in undiluted ascites neutralized the TMUV infectivity to induce the development of cytopathic effects in BHK-21 cells, indicating that 12F11 exhibits a neutralizing activity. The neutralizing activity of 12F11 was confirmed by plaque reduction neutralization test, in which 12F11 reduced significantly the number of plaques produced by TMUV in BHK-21 cells. Western blot analyses of a series of truncated rEDIII proteins showed that the epitope recognized by 12F11 includes amino acids between residues 8 and 77 of EDIII protein. Function analysis demonstrated that 12F11 neutralizes TMUV infection at virus adsorption and at a step after adsorption to a certain extent. The present study provides an important step towards elucidating antibody-mediated neutralization of TMUV.
Innate Immune Receptors and Defense Against Primary Pathogenic Fungi
Authors: Kirkland Theo N. , Fierer Joshua
Published: June 2020

The innate immune system is critical for natural resistance to all pathogenic microorganisms, including fungi. The innate response plays a vital role in resistance to infections before the antigen-specific immune response and also influences antigen-specific adaptive immunity. There are many different receptors for the innate immune response to fungi, and some receptors have been found to play a significant role in the response to human infections with opportunistic fungi. Most human infections are caused by opportunistic fungi, but a small number of organisms are capable of causing infections in normal hosts. The primary pathogenic fungi that cause invasive infections include Blastomyces spp., Cryptococcus gattii, Coccidioides spp., Histoplasma spp., and Paracoccidioides spp. In this review of innate immune receptors that play a role in infections caused by these organisms, we find that innate immunity differs between organisms.
Characterization of Global DNA Methylation in Different Gene Regions Reveals Candidate Biomarkers in Pigs with High and Low Levels of Boar Taint
Authors: Wang Xiao , Kadarmideen Haja N.
Published: June 2020

DNA methylation of different gene components, including different exons and introns, or different lengths of exons and introns is associated with differences in gene expression. To investigate the methylation of porcine gene components associated with the boar taint (BT) trait, this study used reduced representation bisulfite sequencing (RRBS) data from nine porcine testis samples in three BT groups (low, medium and high BT). The results showed that the methylation levels of the first exons and first introns were lower than those of the other exons and introns. The first exons/introns of CpG island regions had even lower levels of methylation. A total of 123 differentially methylated promoters (DMPs), 194 differentially methylated exons (DMEs) and 402 differentially methylated introns (DMIs) were identified, of which 80 DMPs (DMP-CpGis), 112 DMEs (DME-CpGis) and 166 DMIs (DMI-CpGis) were discovered in CpG islands. Importantly, GPX1 contained one each of DMP, DME, DMI, DMP-CpGi, DME-CpGi and DMI-CpGi. Gene-GO term relationships and pathways analysis showed DMP-CpGi-related genes are mainly involved in methylation-related biological functions. In addition, gene–gene interaction networks consisted of nodes that were hypo-methylated GPX1, hypo-methylated APP, hypo-methylated ATOX1, hyper-methylated ADRB2, hyper-methylated RPS6KA1 and hyper-methylated PNMT. They could be used as candidate biomarkers for reducing boar taint in pigs, after further validation in large cohorts.

La démarche du naturaliste et explorateur allemand, unissant l'esthétique, la science et l'éthique, est interprétée ici comme l'une des premières tentatives géopoéticiennes. La recherche d'une relation moins simpliste, plus complexe, entre l'être humain, la Terre et le Cosmos, le voyage considéré à la fois comme plan de vie et plan de travail, la quête d'un langage qui puisse exprimer cette pensée et cette expérience originale du monde, se trouvent liés dans ce texte qui révèle l'analogie entre les voyages d'Alexandre de Humboldt et le parcours géopoétique de Kenneth White.
Thyroid Function in Children with Down Syndrome in the Polish Population: A Case–Control Study
Authors: Zelazowska-Rutkowska Beata , Jakubiuk-Tomaszuk Anna , Cylwik Bogdan
Published: June 2020

Background: Patients with subclinical thyroid disease have few or no clinical symptoms of thyroid dysfunction and thus, laboratory diagnosis is needed. In this context, the objective of the current study was to analyze the prevalence rate and pattern of thyroid function in children with Down syndrome in the Polish population. Methods: A total of 30 children, aged 6–12 years, with cytogenetically confirmed Down syndrome were studied. The control group included 27 children. Results: Of the 30 patients with Down syndrome, 14 (46.7%) had abnormal thyroid profiles. Mean thyroid-stimulating hormone (TSH) and fT4 concentrations in children with Down syndrome were found to be significantly increased compared with the controls (4.30 ± 1.9 µIU/mL, 95% CI: 3.55–5.04 µIU/mL vs. 3.10 ± 1.47 µIU/mL, 95% CI: 2.52–3.68 µIU/mL, P = 0.013, 95% CI: 0.26–2.14, and 1.33 ± 0.23 ng/dL, 95% CI: 1.25–1.42 vs. 1.19 ± 0.14 ng/dL, 95% CI: 1.13–1.25, P = 0.008, 95% CI: 0.04–0.24, respectively). In Down syndrome, subclinical hypothyroidism was recognized in 10 children (33.3%) (high TSH and normal fT4 and fT3 levels). Two children (6.67%) had evident hypothyroidism (high TSH and low fT4). In the control group, subclinical hypothyroidism was diagnosed in four (14.8%) children. Conclusion: Children with Down syndrome may have increased secretion of TSH, even when thyroid hormone and autoantibodies are normal, suggesting that an isolated increase in TSH does not predispose the patient to the development of thyroid disease. We also recommend that all patients with Down syndrome should be screened for thyroid dysgenesis, since they have thyroid dysfunction more frequently as compared to the general healthy population.

Authors: Badri Shirinsadat , Soltani Rasool , Sayadi Mina , Khorvash Farzin , Meidani Mohsen , Taheri Shahram
Published: June 2020

Background:The proposed mechanism of vancomycin-induced nephrotoxicity (VIN) is indirect production of reactive oxygen species in the kidney tissue. This study aimed to investigate the effectiveness of N-acetylcysteine (NAC), an anti-oxidant agent, in the prevention of VIN.Methods:Patients who received vancomycin for any indication were randomly divided to drug (NAC) and control groups. The patients in the drug group received oral NAC 600 mg every 12 hours for 10 days, starting concurrently with vancomycin. Serum creatinine (SCr) levels and blood urea nitrogen (BUN) as well as creatinine clearance (CrCl) and 12-hour urine volume were recorded at baseline, every other day during the study, and 12 hours after the last dose of vancomycin on the 10th day. Furthermore, the cases of acute kidney injury (AKI; ≥ 0.5 mg/dL or at least 50% increase in serum creatinine from baseline) were recorded in the two groups.Results:Over the study period, 84 and 95 patients completed the study in drug and control groups, respectively. SCr and CrCl were significantly lower and higher, respectively, at all-time points (except for baseline) in the NAC compared to the control group. Furthermore, although not statistically significant, 12 cases of vancomycin-induced AKI were observed in the control group (12.63%), while 4 cases (4.76%) were reported from drug group (P= 0.066; relative risk [RR] = 0.377, 95% CI: 0.126–1.124).Conclusion:NAC has the potential for reduction of VIN. However, more studies are necessary to confirm this effect.

Approach to the synthesis of variable data insertion procedures in structure-independent databases
Authors: Grishchenko Andrey S.
Published: June 2020

The aim of developing an approach to the synthesis of variable data insertion procedures in structure-independent databases is to identify and analyze heterogeneities in the existing construction process. Two types of heterogeneities were identified associated with various forms of representing the minimum structural units for constructing the process of constructing the data insertion procedure, as well as semantic heterogeneities associated with the use of elements that are semantically heterogeneous to structural elements of a structure-independent database. To eliminate them, you need to use an approach based on the action designer. It allows to use actions as minimal structural units in the synthesis process, to reveal the meanings of characteristics, presenting them in the form of an action structure. The result of the article is a formulated approach to the synthesis of variable data insertion procedures in structure-independent databases.

Authors: Polenov Maxim Yu. , Kurmaleev Artem O.
Published: June 2020

The objective of the work is to develop software tools that allow to reduce time costs of creating models of complex technical systems. This problem is solved by translating and using model components stored in a distributed storage of external models for the modeling tools chosen by the researcher. Translation of models is carried out using the previously developed Multitranslator environment. To speed up the process of model translation and resolve the uncertainties arising in this case, it is proposed to use an expert system. CLIPS environment was chosen as a tool for creating an expert system. The paper discusses the features of the organization of the expert system interaction with the developed distributed storage of external models based on the CLIPS API. The result of the work is the development of the approach of intellectualization of multilanguage translation tools for the use of external models in the modeling of complex systems.

Authors: Serra Payeras Pedrona , Prat Grau Maria , Nicolino Aline da Silva , Soler Prat Susanna , Silva Ana Márcia
Published: June 2020

Se analiza cómo se ha introducido la perspectiva de género en los grados universitarios que capacitan al profesorado de educación física en Brasil y España. A partir del análisis de contenido de los proyectos curriculares o guías docentes de 65 instituciones de educación superior brasileñas (7,8% del total) y 16 universidades españolas (45%) que estaban disponibles en línea. Se ha utilizado la teoría iniciada por Tetreault (1985), en la que destaca cinco niveles de inclusión del conocimiento sobre las mujeres y las relaciones de género. La investigación ha permitido constatar que la presencia de la perspectiva de género es puntual y anecdótica en el proceso de formación de los y las profesionales de ambos países a pesar de la existencia de marcos legales que establecen la necesidad de incorporarla. Los resultados confirman que la construcción del conocimiento y las diversas formas de transmitirlo influyen en la transformación o la reproducción de las relaciones hegemónicas de género. Las aportaciones de este estudio muestran la necesidad de cuestionar la situación actual y apelar a la reflexión institucional en ambos contextos para incorporar cambios sustanciales en la formación del profesorado y así fomentar la transformación social desde las universidades.
Active contour driven by scalable local regional information on expandable kernel
Authors: Faisal Amir , Pluempitiwiriyawej Charnchai
Published: June 2020

An active contour that uses the pixel’s intensity on a set of expandable kernels along the propagating contour for image segmentation is presented in this paper. The objective is this study is to employ the scalable kernels to attract the contour to meet the desired boundary. The key characteristics of this scheme is that the kernels gradually expand to find an object’s boundary. So this scheme could penetrate to the concave boundary more effective and efficient than some other schemes. If a Gaussian kernel is applied, it could trace the object with a blurred or smooth boundary. Moreover, the directional selectivity feature enables in capturing two edge’s types with just one initial position. Its performance showed more desirable segmentation outcomes compared to the other existing active contours using regional information when segmenting the noisy image and the non-uniform (or heterogeneous) textures. Meanwhile, the level set implementation enables topological flexibility to our active contour scheme.

Authors: Nulhakim Lukman , Rozana Monna , Yuliarto Brian , Makino Hisao
Published: June 2020

The electrical and optical properties of Ga-doped ZnO (GZO) thin film prepared by direct current (dc) magnetron sputtering were investigated. The GZO thin film was deposited on a glass substrate at a substrate temperature (Ts) of room temperature (RT), 150 °C, and 200 °C using DC power of 100 W and an Ar gas flow rate of 450 sccm. The thickness of films was maintained at about 200 nm by controlling the deposition rate of about 12.5 nm/minute. The result showed that the electrical properties improved with increasing Ts. The films deposited at Ts of 200 °C showed the lowest resistivity, highest hall mobility, and carrier concentration compared to other Ts. The average transmittance of the films in the visible range (380-750 nm) was approximately 86.04%. The value of the optical band gap (Eg) was approximately 3.8 eV. The results suggested that GZO films deposited by DC magnetron sputtering at Ts of 200 °C can be applied to transparent conducting oxide (TCO) as an electrode in optoelectronic applications such as solar cells, LEDs and display technology.

Published: June 2020

The paper describes the rapid arising of a national-level research information management infrastructure (RIM) in India as a case study for a bottom-up Current Research Information System (CRIS) implementation strategy. Less than a year and a half after its first launch, the Indian Research Information Network System (IRINS) has become a widespread institutional RIM asset with over 180 instances at Indian research-performing organisations. As a result, India is currently leading the classification by number of CRIS per country in the euroCRIS Directory of Research Information Systems (DRIS), followed by Norway and the United Kingdom.As a background to the case study, the broad international CRIS context is also analysed. The causes for the quick rise of such systems are examined, together with their national-level implementation models in various countries and the differences between CRIS and expert finder systems.
A configuração teórica da Produção Textual na Base Nacional Comum Curricular: um olhar para a Transposição Didática
Authors: Do Nascimento Antonio Naéliton , De Araújo Denise Lino
Published: June 2020

O debate acerca de um currículo nacional comum tem gerado discussão entre os atores da esfera educacional, visto que a construção de uma proposta curricular dessa natureza parece ser o objeto em torno qual várias políticas educacionais orbitam. Nesse contexto, surge a Base Nacional Comum Curricular (BNCC, 2018), cujo objetivo central é definir as aprendizagens essenciais às quais todos os alunos devem ter acesso na Educação Básica. Levando em consideração a área de Linguagens e a disciplina de Língua Portuguesa, podemos perceber que (re)configurações teóricas foram realizadas durante a elaboração desse documento, portanto, merecem ser elucidadas, sobretudo se considerarmos o professor, leitor-alvo da BNCC. Assim sendo, este artigo tem como foco apresentar a (des)montagem (LE GOFF, 1997) da versão homologada da BNCC relativa ao nível de ensino médio, propondo uma análise de verbetes relacionados ao eixo Produção Textual, a partir de pesquisa documental, de base qualitativo-interpretativista e situada no campo aplicado dos estudos da linguagem. Para tal investigação, apoiamo-nos na teoria da Transposição Didática, Chevallard (2001), Marandino (2004); na Linguística Textual, Brait (2016), Koch (2009); e nos Estudos sobre Currículo, Silva (2005), Macedo (2012), entre outras fontes bibliográficas. Os resultados apontam para uma expressiva heterogeneidade terminológica voltada à produção textual, revelando uma filiação grafocêntrica, mas também multissemiótica, do objeto investigado. Ademais, o termo produção textual apresenta imprecisão conceitual em sua reconfiguração, gerando sobreposição de objetos e ambiguidade de leitura na BNCC.
Literatura e representação: uma análise crítica de Cacau, de Jorge Amado
Authors: Badaró Santos José Otávio , Dos Santos Oton Magno Santana , Souza Mateus Santos
Published: June 2020

O presente texto pretende analisar o romance Cacau (1933), de Jorge Amado, em uma perspectiva da literatura como representação, na esteira dos estudos de Louis Marin e Roger Chartier, considerando o texto literário como a representação das sensibilidades de determinados homens, em determinadas épocas, da ideia que faziam de sua própria sociedade, dos significados que almejavam construir, ou a maneira como apreendiam o mundo em que viviam. Nesse sentido, propomos uma oposição à ideia de que a referida obra, circunscrita pela crítica marxista como romance proletário e regionalista, é uma homologia das estruturas sociais da realidade que lhe é referente, uma vez que buscamos construir um estudo mais próximo das correntes teóricas que investigam a cultura não como um nível de realidade adstrito às determinações socioeconômicas, mas como uma dimensão complexa do homem que, de maneira alguma, pode ser explicada por modelos reducionistas e deterministas. Assim, a noção de representação nos permitiu compreender as relações que o autor ou o grupo do qual ele fez parte mantiveram com o mundo social, como uma construção multifacetada, constituída de posições, escolhas e interesses. Baseado em Jauss, propomos que não há um sentido oculto, mas uma significação que se dá na relação obra e leitor.

Introduction. To determine the strategic goals of transforming the financial system of Ukraine, it is especially important to study the experience of successful and effective world economies. The iconic examples of such systems are the financial systems of Canada and the United States.

The purpose of this article is to analyze the dynamics of the United States and Canadian financial systems’ indicators and determine the characteristics of the development of these countries in terms of their future closest financial integration.

Methods. The research methodology was based on a combination of such scientific methods as: generalization, graphic and comparative analysis, analysis and synthesis, this made possible to determine the development details of the USA and Canadian financial system and the possibilities for their financial sector further integration and harmonization.

Results. The USA and Canadian financial systems are analyzed, especially, the causes and consequences of the financial integration of these systems, as well as possible ways for their further development are thoroughly studied. Such stability indicators of the financial system as inflation, money supply, interest rate dynamics and public debt are researched. Risk assessment of the further development of the financial system of the USA and Canada is also done.

Conclusions. The Canadian and US financial systems are closely interconnected through many years of cooperation. Accordingly, the risks in these systems are the same, and factors that are similar for both countries hinder their development. Although, regardless of these factors, in general, the development of the financial systems of the United States and Canada is stable and consistent.

Published: June 2020

We performed an open-air-type plasma treatment of polytetrafluoroethylene (PTFE) at atmospheric pressure to increase the adhesion strength between PTFE and an Ag metal film obtained from Ag ink. When PTFE was Ar plasma-treated without H2O addition for 600 s, the coloration of the PTFE surface occurred, and the Ag/PTFE adhesion strength was 0.06 N mm−1. This adhesion strength was the same as that of the as-received PTFE (0.04 N mm−1). When the PTFE was Ar plasma-treated with the H2O addition of ca. 0.1% for 600 s, coloration did not occur, and the Ag/PTFE adhesion strength increased to 1.03 N mm−1. The effects of H2O addition to the Ar plasma on the Ag/PTFE adhesion strength, surface chemical composition, surface morphology, and the surface hardness were investigated and discussed in this study.

In this study, fish oil & cottonseed oils were used to produce their individual methyl esters using a mixed base catalyst (Sodium hydroxide & di-sodium phosphate). The produced biodiesels were characterized to check the quality of biodiesel and to establish the feasibility of using the mixed base catalyst for production of biodiesels. The biodiesel was characterized by FTIR (Fourier Transform infrared spectrometry) and GC (Gas Chromatography) tests and the other important properties of biodiesel were found out and compared with that of diesel. FTIR test confirms complete conversion of biodiesel from individual oils and the fuel properties were found to be within the range prescribed in ASTM standards. GC analysis has shown presence of more unsaturated fatty acids in cottonseed oil and less in fish oil biodiesel throwing some light on the stability of the fuels. The present characterization studies has established the potential use of mixed base catalyst during transesterification reactions.

In this paper, we are discussing about a heart disease called Arrhythmia and how it can be identified using the Electrocardiogram. Electrocardiogram (ECG) is a graphical form for electrical activity of cardiac muscle. A healthy human heart beats, 72 times per minute under normal conditions. For every heartbeat the cardiac muscle undergoes specific electrical activity which identifies the pattern in the ECG signal. It consists of PQRST wave which represents heart functions. The patterns of the ECG signal change due to the abnormalities in the heartbeat. The abnormality in the ECG is called Arrhythmia.

To design and develop an automated surveillance system to detect and intimate the presence of animals, monitoring the health parameters of the trekkers and to detect fire in the dense forest. Using sensors and wireless technology that communicate to the base station using wireless communication. In this project the image processing technique is explored for the detection of animals so that any change in pattern then the trekkers and base station are alerted. For the communication process, a wireless underground sensor network is employed which has a lot of interlinked nodes. This is because internet usage is not effective in the dense and reserved forest area. Node to node communication is performed for efficient information sharing with the base station and the communication process for trekkers is carried on with wireless sensor networks thus provides warning information to the trekkers. Animal detection based applications have a very important role in many real-life situations and also detection of forest fire in dense forest is hard and fast-spreading. Therefore there must be automation and faster means of communication.

Mobile Ad hoc Network is an assortment of free hubs that can convey one another. These hubs are self-composed hub, which doesn't have any fixed framework like base station, radio wires, and so forth. The hubs with in its range can have an immediate correspondence if not it utilizes a moderate hub for transmitting the information. Each node will act as both host and router. The nodes can join or leave the network anytime and makes the network topology. Network topology is dynamic in nature. Because of the dynamic behavior the detection of trust value is difficult for intermediary node. Trust should be managed in the network ie., the network has different behaviors like malicious, selfishness, unhealthiness, etc., due to these behaviors the trust of an intermediary node is difficult to calculate. Right now safe routing is performed by the improvement of convention which yields the minimization of trust inclination and boosts the application execution. This study compares different trust management framework and compare the trust level based on the metrics and outlines the issues and future ideas.

Need of green energy can be catered with the support of major share of wind power generation systems in the global energy scenario. Power quality of generated wind power depends on several factors. Wind velocity is one of the major factors producing fluctuations in the generated output voltage. These fluctuations cause visible disturbance to human eyes, known as voltage flicker. The wind farms affect performance of Grid due to variations in wind speed with respect to time. The paper explains measurement of flicker, flicker level severity index along with flicker mitigation technique. Flicker is observed in the power generated with help of Permanent Magnet Synchronous Generator (PMSG), where wind velocity is changing continuously. After employing converter control strategy, reduction in flicker level severity index is observed. The system is simulated using PSCAD/EMTDC, a powerful simulation software. Result shows that Grid side converter control helps to mitigate flicker effect.
