Published: August 2020

ABSTRAKMakalah ini membahas desain dan simulasi generator magnet permanen fluks aksial 500 W, 220 V, 500 rpm, 1 fasa, stator tunggal tanpa inti besi lunak dan rotor ganda berbahan baja karbon. Tujuan studi adalah untuk mengetahui performa generator pada dua jenis pembebanan yaitu beban RL dan ZL. Metode perhitungan desain dilakukan secara analitik dan numerik menggunakan perangkat lunak FEMM 4.2 dengan berbasis pada dimensi magnet permanen komersil. Performa generator yang dianalisis meliputi tegangan terminal, daya keluaran dan efisiensi. Hasil simulasi menunjukkan bahwa ketika diberi beban RL, daya keluaran dan efisiensi generator lebih tinggi dibanding ketika diberi beban ZL. Grafik tegangan terminal dari kedua jenis pembebanan tersebut sebagian berimpit tetapi pada beban RL tingkat penurunannya lebih tajam disebabkan tegangan jatuhnya lebih besar. Dari semua hasil perhitungan dan simulasi, dapat disimpulkan bahwa generator menunjukkan performa yang baik pada kedua jenis pembebanan dengan efisiensi sekitar 80%.Kata kunci: generator, magnet permanen, fluks aksial, stator tunggal, rotor ganda ABSTRACTThis paper discusses the design and simulation of 500 W, 220 V, 500 rpm axial flux permanent magnet generators, with the construction of coreless, single stator, and double rotor made of carbon steel. This study aims to find out the performance of the generators in two types of loadings, namely RL and ZL loads. The design calculation method is done analytically and numerically using FEMM 4.2 software based on the dimensions of commercial permanent magnets. The generator performances analyzed include the terminal voltage, the output power, and the efficiency. From the simulation results, it is known that under load RL, the output power and efficiency are higher than under load ZL. The terminal voltage graphs of the two types of loadings partially coincide but at the RL load, the rate of the decline is sharper due to the greater voltage drop. From all the results, it can be concluded that the generator shows good performance on both types of loads with a quite high efficiency, which is around 80%.Keywords: generator, permanent magnet, axial flux, single stator, double rotor

Authors: Saihu Saihu , Åžahin Cemal
Published: August 2020

This paper discusses the harmonious dialectics process between Hindus and Muslims throughâ€˜urf or local wisdom which is believed to have philosophical, sociological, and psychological values with plural-multicultural nuances for the community of Jembrana, Province of Bali. This paper focuses on searching the effectiveness of someâ€˜urf or local wisdom that functions as a means to interact between two religious communities that lead to peaceful practices on Hindu-Muslim communities in Jembrana-Bali. The data sources are field observations and unstructured interviews from March-July 2019. This study is field research using a method of a case study. The results found that the dialectics process with a multicultural nuance between Hindus and Muslims in Jembrana is through theâ€˜urf or local wisdom, namely male, ngejot, rebana, and mekepung traditions. Further, from these four traditions, there is a process of active involvement, constructive understanding, and efforts to find joint commitments from various commitments, so that a sense of brotherhood and understanding of the diversity between the two religious communities becomes extremely close. This dialectic can also shape the character of Hindu and Muslim communities in Jembrana to be humanist, tolerant, and inclusive, this phenomenon then leads to the process of association, integration, complementation, and sublimation.

HARNESSING IN INDIAN CONTEMPORARY ART AND INDIAN MEDIA MARKET: THE FUTURE POSSIBILITIES
Authors: Porwal Tina
Published: August 2020

In primitive times, humans first created sketches in caves with coal. The development of time introduced man's colours and gradually begun to wind up the shades of nature even in colours. Then gradually the chemical colours (substance colours) were used for painting. Alongside every one of these advancements, the artist has not abstained from illustration on the PC while changing himself after some time. The world of art and artist is extremely bizarre and stranger. There is also attraction and fear in this world and there is always a neglected place for this world. In contemporary times when the person has reached the moon, the development of technology has reduced the whole world Ground Flood has brought the whole world to a stage of art And consumerism and marketism have pulled out the art and made a big canvas, Then this is the right time, when a person evaluates how the thinking of the common man and the artist has changed over the art. The commercialization of art is posing a threat. The artist is from middle-class society, which starts working from the beginning to improve its economic condition, influenced by the market. Some artists are destroyed in such a situation, some save themselves, who save themselves, they give something to art. The craft of craftsmanship isn't awful, it is awful to be impacted by the market. The art of the market is growing fast in contemporary times and in the same way, the art market is fast becoming a thing. Naturally, now art has started declaring the object of market value and in this way the meaning of art is changing rapidly. And the meaning of his originality is also changing. At this time, it is very difficult to differentiate between genuine or real and fake in painting in the contemporary art market. And counterfeit paintings are also being sold in the market.

Examination Timetabling Problem is one of the optimization and combinatorial problems. It is proved to be a non-deterministic polynomial (NP)-hard problem. On a large scale of data, the examination timetabling problem becomes a complex problem and takes time if it solved manually. Therefore, heuristics exist to provide reasonable enough solutions and meet the constraints of the problem. In this study, a real-world dataset of Examination Timetabling (Toronto dataset) is solved using a Hill-Climbing and Tabu Search algorithm. Different from the approach in the literature, Tabu Search is a meta-heuristic method, but we implemented a Tabu Search within the hyper-heuristic framework. The main objective of this study is to provide a better understanding of the application of Hill-Climbing and Tabu Search in hyper-heuristics to solve timetabling problems. The results of the experiments show that Hill-Climbing and Tabu Search succeeded in automating the timetabling process by reducing the penalty 18-65% from the initial solution. Besides, we tested the algorithms within 10,000-100,000 iterations, and the results were compared with a previous study. Most of the solutions generated from this experiment are better compared to the previous study that also used Tabu Search algorithm.

Published: August 2020

Background: The temperature and salivary pH in a person's mouth are highly dynamic (e.g., before, during, and after eating) and so restorations in a cavity must be resilient to these variable conditions. Temperature and immersion conditions affect the mechanical properties of a restoration. This study aimed to determine the effect of environmental conditions on diametral tensile strength (DTS) and surface microhardness of a resin composite with alkaline fillers or zirconia–reinforced glass ionomer cement (Zr-reinforced GIC). Method: Thirty specimens of a resin composite with alkaline fillers (Cention-N, Ivoclar-Vivadent, Lichtenstein) and 30 specimens with zirconia-reinforced GIC (Zirconomer, Shofu, Japan) were stored at different conditions (23°C and 37°C; with and without immersion in water) for 24 hours. DTS was tested with a Universal Testing Machine (AGS-X series, Shimadzu, Japan) and surface microhardness was tested with a Vickers Microhardness tester (HMV-G Series Micro Vickers Microhardness Tester, Shimadzu, Japan). Data were analyzed statistically using a one-way ANOVA test (and Shapiro-Wilk test. Result: The values of microhardness and DTS increased significantly both for the composite resin alkasite and zirconia-reinforced GIC with increasing temperature in the groups without immersion. However, there was a significant decrease in microhardness and DTS after immersion in distilled water at 37°C for both the composite resin alkasite and zirconia-reinforced GIC. Conclusion: It can be concluded that storage conditions affect the microhardness and DTS of resin composite Alkasite and Zirconia-reinforced GIC

Sosyal Statü Farklılıklarının Kur’ân’a Yansımaları: Din Adamları ve Halka Yönelik Hükümlerin Mukayesesi
Authors: ERGÜN Mehmet
Published: August 2020

Kur’ân’a göre genel manada bütün insanlar dini sorumluluk açısından eşit olmakla birlikte âyetlerin satır aralarında kişilerin sosyal statülerine göre bazı farklı hitaplar ve hükümler bulunmaktadır. Araştırmalar serisi halinde ele aldığımız bu farklılıklar arasından bu çalışmamızda din adamları ve halk arasında gerek hitap gerekse sorumluluk açısından değişen hükümleri inceleyeceğiz. Tarih boyunca toplumlardaki görev paylaşımı prensibi gereği her dinin bağlıları arasında bir din adamı sınıfı olagelmiştir. Halkın dini konu-larda bilgi edinme ve rehberlik ihtiyacından doğan bu grubun özellikleri dinlere göre farklılıklar göster-mektedir. Kur’ân’da, özellikle Yahudi ve Hıristiyan din adamlarını konu edinen çok sayıda âyet bulun-maktadır ve bu ayetlerin çoğunluğunda onların Tanrı’ya ve insanlara karşı sorumluluklarını yerine getir-mediklerinden bahsedilmektedir. Bundaki amaç İslam’da halkı din alanında aydınlatacak ve onlara reh-berlik edecek kişilerin aynı hatalara düşmemeleri konusunda uyarmaktır. İslam dininde bazı dinlerin ak-sine ruhban sınıfı bulunmamakta ve din adamı ile halk arasındaki çizgi diğer dinlere göre daha esnek bir yapı arz etmektedir. Helal-haram ve emir-yasak bakımından halk ile din adamı arasında hiçbir farklılık bulunmamaktadır. Ancak yine de Kur’ân, din konusunda bilgi ve idrak açısından halka göre daha üstün düzeyde olan kişilerden bazı dini sorumlulukları yerine getirmede daha fazla hassasiyet beklemektedir.

Visual forms of communication are ubiquitous in media, educational texts, government reports, and scientific publications. Two challenges immediately come to mind and drive the research agenda we have been following. We need to know that these graphs are provably understandable. We also need to know that the personnel have the skills to understand the information being presented when it is presented well. In this paper, we assert that the right way to achieve both goals relies on perceiving what are the visual equivalents of sentences from graphs.

The human response to the COVID-19 pandemic set in motion an unprecedented shift in human activity with unknown long-term effects. The impacts in marine systems are expected to be highly dynamic at local and global scales. However, in comparison to terrestrial ecosystems, we are not well-prepared to document these changes in marine and coastal environments. The problems are two-fold: 1) manual and siloed data collection and processing, and 2) reliance on marine professionals for observation and analysis. These problems are relevant beyond the pandemic and are a barrier to understanding rapidly evolving blue economies, the impacts of climate change, and the many other changes our modern-day oceans are undergoing. The “Our Ocean in COVID-19” project, which aims to track human-ocean interactions throughout the pandemic, uses the new eOceans platform (eOceans.app) to overcome these barriers. Working at local scales, a global network of ocean scientists and citizen scientists are collaborating to monitor the ocean in near real-time. The purpose of this paper is to bring this project to the attention of the marine conservation community, researchers, and the public wanting to track changes in their area. As our team continues to grow, this project will provide important baselines and temporal patterns for ocean conservation, policy, and innovation as society transitions towards a new normal. It may also provide a proof-of-concept for real-time, collaborative ocean monitoring that breaks down silos between academia, government, and at-sea stakeholders to create a stronger and more democratic blue economy with communities more resilient to ocean and global change.

Engineering applications of high strength alloys are often restricted due to their poor tensile elongation or ductility. Alloys with high yield strength typically exhibit limited strain-hardenability (the difference between tensile and yield-strengths), leading to reduced tensile ductility. Deformation twinning, resulting in high strain hardenability, can lead to enhanced tensile elongation in single-phase solid solutions, including high entropy alloys (HEAs). However, alloy systems involving a solid solution matrix strengthened with an intermetallic phase do not exhibit deformation twinning, thus limiting their tensile ductility. We have successfully exploited deformation twinning in a novel HEA, strengthened using nano-lamellar ordered multi-component intermetallic precipitates, leading to an exceptionally high yield strength (~1630 MPa), good tensile ductility (~15%), and ultimate tensile strength (~1720 MPa), higher than any other reported fcc based alloy. Exploiting deformation twinning in a two-phase metal-intermetallic system, offers a new paradigm for addressing the strength-ductility trade-off plaguing alloy design.
The psychology of obesity: An umbrella review and evidence-based map of the psychological correlates of heavier body weight

Published: August 2020

Psychological factors may explain why some people develop obesity and others remain a normal weight during their life course. We use an umbrella review approach to build an evidence-based map of the psychological correlates of heavier body weight. Synthesising findings from 42 meta-analyses that have examined associations between psychological factors and heavier body weight, we assessed level of evidence for a range of cognitive, psychosocial and mental health individual difference factors. There is convincing evidence that impaired mental health is associated with heavier body weight and highly suggestive evidence that numerous cognitive factors are associated with heavier body weight. However, the relatively low methodological quality of meta-analyses resulted in lower evidential certainty for most psychosocial factors. Psychological correlates of heavier body weight tended to be small in statistical size and on average, people with obesity were likely to be more psychologically similar than different to people with normal weight. We consider implications for understanding the development of heavier body weight and identifying effective public health interventions to reduce obesity.
Under the Umbrella of Prosocial Behavior – A Critical Comparison of Paradigms
Authors: Behrens Friederike , Kret Mariska
Published: August 2020

Despite the discontent, cruelty, and warfare that fill the daily news, people show tremendous capacities to help and cooperate with others. Prosocial behavior is used as an umbrella term capturing the diversity of selfless acts. As such, researchers have developed a variety of tasks and it is crucial to verify that they measure the same underlying construct of prosocial behavior. Previous studies have focused on comparing anonymous, one-shot economic games providing evidence for behavioral consistency across games. The current study extends these findings by (i) comparing both repeated economic and naturalistic interactive games in a within-subject design, and (ii) letting participants play in face-to-face dyadic settings. In total, 74 participants completed six tasks: three variants of a social dilemma game, an Egg Hunt game measuring helping behavior, a group decision-making paradigm requiring communication skills, and a Tangram game where participants solved puzzles together. A Principal Component Analysis revealed that two components best describe the behavior in these tasks. The three social dilemma games loaded on the first component, termed “social dilemma games”. These games were distinct from the interactive games and the helping and decision-making tasks loaded on the second component, termed “naturalistic games”. The Tangram game was unrelated to all other games. These findings suggest that the behavioral consistency observed in economic games has its limits to generalize to other types of tasks and emphasizes the importance of choosing the appropriate (combination of) paradigms to measure prosocial behavior. Theoretical and methodological differences between tasks are discussed to explain these findings.
The Effect of Accuracy Instructions on Coronavirus-Related Belief Change Following Conversational Interactions
Authors: Vlasceanu Madalina , Coman Alin
Published: August 2020

In a high-risk environment, such as during an epidemic, people are exposed to a large amount of information, both accurate and inaccurate. Following exposure, they typically discuss the information with each other. Here, we assess the effects of such conversations on beliefs. A sample of 126 M-Turk participants rated the accuracy of a set of COVID-19 statements (pre-test). They were then paired and asked to discuss these statements (low epistemic condition) or to discuss only the statements they thought were accurate (high epistemic condition). Finally, they rated the accuracy of the initial statements again (post- test). We do not find an effect of the epistemic condition on belief change. However, we find that individuals are sensitive to their conversational partners and change their beliefs according to their partners’ conveyed beliefs. This influence is strongest for initially moderately held beliefs. In exploratory analyses, we find that COVID-19 knowledge is predicted by trusting Doctor Fauci, not trusting President Trump, and feeling threatened by COVID-19, whereas believing COVID-19 conspiracies is predicted by trusting President Trump, not trusting Doctor Fauci, news media consumption, social media usage, and political orientation. Finally, we find that news media consumption positively predicts believing COVID-19 conspiracies, even when controlling for demographic variables including political ideology, and that this effect is not driven by a particular news network, but instead it is a general effect of news media consumption.
What do people know about the senses? Understanding perceptions of variation in sensory experience
Authors: Cuskley Christine , Saitis Charalampos
Published: August 2020

Academic disciplines spanning cognitive science, art, and music have made strides in understanding how humans sense and experience the world. We now have a better scientific understanding of how human sensation and perception function both in the brain and in interaction than ever before. However, there is little research on how this high level scientific understanding is translated into knowledge for the public more widely. We present descriptive results from a simple survey and compare how public understanding and perception of sensory experience lines up with scientific understanding. Results show that even in a sample with fairly high educational attainment, many respondents were unaware of fairly common forms of sensory variation. In line with the well-documented under representation of sign languages within linguistics, respondents tended to under-estimate the number of sign languages in the world. We outline how our results represent gaps in public understanding of sensory variation, and argue that filling these gaps can form an important early intervention, acting as a basic foundation for improving acceptance, inclusivity, and accessibility for cognitively diverse populations.

Twin studies indicate that 30-40% of the disease liability for depression can be attributed to genetic differences. Here, we assess the explanatory ability of polygenic scores (PGS) based on broad- (PGSBD) and clinical- (PGSMDD) depression summary statistics from the UK Biobank using a sample of adults (N=210; 100% European Ancestry) who have been extensively phenotyped for depression and related neurocognitive traits (e.g., rumination, emotion regulation, anhedonia, and resting frontal alpha asymmetry). PGS associations with depression severity and diagnosis were generally modest (β’s ranging from 0.150 (PGSMDD on current depression diagnosis) to 0.177 (PGS PGSBD on current depression diagnosis)). Overall, the UK Biobank-derived broad-depression PGS had a small but significant association with suicidal ideation (such that higher PGSBD was associated with suicidal ideation) but its association with other neurocognitive variables was minimal. The UK Biobank-derived MDD PGS had limited transportability to endo/intermediary phenotypes measured in this study.
Statistical Learning of Target Location Probability in Children and Adults

Learning environmental regularities allows us to make predictions and guide behavior. Growing evidence of location probability learning (LPL) has shown that the statistical regularity of target locations affects spatial attention allocation. However, past studies on LPL have mostly focused on adults’ learning. To achieve a comprehensive understanding of the mechanism of this learning, we investigated the effect of target location probability on 5- to 9-year-old children’s visual search in comparison with that of adults. Both children and adults responded faster when the target appeared in the high probability “rich” quadrant than in the low probability “sparse” quadrants of the search space. This attentional bias toward the rich quadrant persisted even when the target was equally likely to appear in all four quadrants. Importantly, the magnitude of the bias was constant across various ages of participants and did not depend on individual differences in executive functions. Taken together, these results provide novel and converging evidence that implicit statistical learning of target locations occurs early in development and remains stable until early adulthood, which is a distinct developmental pattern from explicit goal-driven spatial attention learning.
