Instantaneous Active and Reactive Power Control Using Direct Power Control Strategy for Multilevel Multistring Inverter Fed Photovoltaic System
Authors: Manoharan Balamurugan , Sahoo Sarat Kumar
Published: March 2021

This paper presents the Direct Power Control (DPC) strategy for Multilevel Multistring Inverter fed Photovoltaic (PV) system to control the instantaneous active and reactive power. The proposed system consists of PV strings, boost converter and three phase three level cascaded H-bridge (CHB) inverter. In multistring topology, each PV string is connected to the dc/dc converter and the distributed MPPT control algorithm is connected to the central inverter. The Space Vector Modulation (SVM) based DPC approach is used to obtain the constant switching frequency and reduced power ripple. The detailed model of the proposed system is developed in Matlab to evaluate the performance. A laboratory based prototype of the proposed system is developed to realize the system in real time. dSPACE DS1103 is used as the control interface to perform the real time implementation (RTI). Power Quality Analyser (PQ-Box 200) is used to analyse the system parameters like voltage, current and Total Harmonic Distortion (THD) of inverter. The effectiveness of the proposed system has been validated with the help of simulation and the experimental results.

Published: March 2021

The idea about this proposed work, to know the Distributed Generation (DG) impact on distribution scheme. This is to improve the performance of the system using power loss reduction and voltage development. In this proposed work Wind Turbine (WT) and Photo-Voltaic (PV) units were taken for DGs and various algorithms are tested to get the effect of DG on network. In this paper one new hybrid algorithm is proposed to have optimal size and location of various types of DGs. Initially, active and reactive power losses of the test system and voltage at every bus of the test system were examined using Back and Forward (B/FW) Sweep technique. Similarly, Gravitational Search Analysis (GSA), BAT Analysis (BA) and Ant Lion Optimization (ALO) techniques were utilized to examine the parameters of the same test system. Finally, all the constraints were compared with projected hybrid approach. All the algorithms have tested on IEEE-33 and IEEE-69 standard test systems. Furthermore, the MATLAB simulation is used to get the optimal allocation of DGs.
A New Improved Variable Step Size MPPT Method for Photovoltaic Systems Using Grey Wolf and Whale Optimization Technique Based PID Controller
Authors: Abderrahim Zemmit , Eddine Herraguemi Kamel , Sabir Messalti
Published: March 2021

In this work, we have developed two new intelligent maximum power point tracking (MPPT) techniques for photovoltaic (PV) solar systems. To optimize the PWM duty cycle driving the DC/DC boost converter, we have used two optimization algorithms namely the whale optimization algorithm (WOA) and grey wolf optimization (GWO) so we can tune the PID controller gains. The oscillation around the MPP and the fail accuracy under fast variable isolation are among the well-known drawbacks of conventional MPPT algorithms. To overcome these two drawbacks, we have formulated a new objective fitness function that includes WOA/GWO based accuracy, ripple, and overshoot. To provide the most relevant variable step size, this objective fitness function was optimized using the two aforementioned optimization algorithms (i.e., WOA and GWO). We have carried out several tests on Solarex MSX-150 panel and DC/DC boost converter based PV systems. In the simulation results section, we can clearly see that the two proposed algorithms perform better than the conventional ones in term of power overshoot, ripple and the response time.

Published: March 2021

The use of high voltage direct current based voltage source converter (VSC-HVDC) in power transmission systems knows a great progress in recent years. Above all, with the new generation of power electronics converters such as the modular multi-level converter (MMC), with his scalable structure it can theoretically meet any voltage level requirement, which allows to increase the size of the power transferred compared to conventional converters. In this sense, this paper presents a study of a VSC-HVDC system based on a modular multi-level converter (MMC). The main objective of this work is to analyze the performance of the VSC-HVDC system based MMC without the AC filters and its control in the event of a fault, during set point changes and unbalanced grid conditions. After realization a mathematical model of the system studied and its control, simulations are done over in Simpower System/Matlab. The results obtained confirm the robustness of the system control and the system gives a good energy quality, that manifests by a good output currant and voltage curves with no need to use a voluminous AC filter.
Swinburne on Physicalism and Personal Identity
Authors: Snowdon Paul
Published: March 2021

In chapter 2 Swinburne rejects physicalism for two reason. The first is that it is committed to entailments that do not exist. It is suggested that this reason is questionable both because there is no persuasive reason to deny there are such entailments, and also no reason to think that physicalism has such entailments. The second reason is that the mental involves privileged access by the subject and physical features do not allow privileged access. It is proposed that the physical does in fact permit privileged access. In chapter 3 Swinburne defends the Simple View of personal identity. The reasoning is very complex and rich, but it is proposed that Swinburne has not really shown that a reductionist account cannot be correct.
Does Anger Toward God Moderate the Relationship Between Religiousness and Well-Being?
Authors: Aditya Yonathan , Ariela Jessica , Martoyo Ihan , Pramono Rudy
Published: March 2021

Most of the current research has found that highly religious people have better well-being compared to people with low religiousness. However, the former group is not immune from occasionally feeling anger toward God, which has an adverse effect on well-being. The purpose of this research is to study whether anger toward God moderates the effect of religiousness on the well-being of Christian college students. The data were derived from 228 respondents (55 male) from a religious university using the Four Basic Dimensions of Religiousness (4-BDRS), the Attitude toward God Scale (ATGS-9), and the Satisfaction with Life Scale (SWLS). The results of the moderation analysis using Process version 3 demonstrated that Anger toward God significantly moderated the effect of religiousness toward well-being (b = .01, 95% Cl [.001, .023], t = 2.14, p < .05). The higher the level of anger toward God, the lesser the effect of religiousness on well-being. Therefore, it is essential for students to resolve their divine struggles. The implications and applications of this study are discussed.

Strategic Decision Making: The Effects of Big Data
Authors: C Turner Harvey , Atkinson David
Published: March 2021

This study aimed to understand the emerging effects big data is having across different business functions as well as how much the insights gathered, from big data sets, are starting to influence business strategy. The literature highlights a lack of understanding around big data, with very little research focusing on big data’s applications outside of short term marketing strategies. This research investigated the potential barriers to big data integration within businesses, and sought to understand how these could be removed. In order to achieve an in depth understanding, an interview based approach was used. A wide range of business sources were examined to further understand the gaps identified by previous research. Primary research took the form of in-depth interviews. Respondents were carefully selected based on industry knowledge and experience, working for companies such as Ebiquity PLC, Satalia and Barclays. The interviews were used to compare and contrast the experts’ opinions and establish whether the key themes identified in the literature held true in the primary research. This approach enabled real insight to be gathered in order to concisely examine and critique the current literature as well as enabled further themes to be investigated. This investigation found how critical big data is becoming to business success, including understanding an emerging gulf between those who have adopted data big sets and those who have not. It was also understood that, on the whole, knowledge and understanding is lagging far behind benchmarks set by some businesses. The paper concludes by explaining why big data is not influencing business strategy. A focused understanding approach is outlined as the preferred solution to bridge the gulf between the ‘haves’ and ‘have not’s’.

Published: March 2021

ABSTRACTIntroduction: Ear protection equipment is indispensable for workers exposed to noise exceeding the threshold value. Introduction: Many studies have shown that the level of labor compliance with the use of ear protection equipment is influenced by the length of work and age of the workers concerned. However, many studies also show different conditions with the results of these studies. For this reason, this study was conducted to determine how the influence of the work period and age of workers on the compliance with the use of ear protection equipment at PT X animal feed industry. Methods: The method used was observational with a cross-sectional approach. The number of population selected from animal feed production workers was 30 workers. The sample was obtained using a simple random sampling calculation of 28 workers. The analysis was done using contingency coefficient statistical tests. Results: The number of workers in the study area whose tenure <12 years is 50% and whose age <37 years is was also 50%. By using the contingency coefficient, it is known that there are 39.3% and 35.7% of 64.3% of workers who were not compliant with the useof ear protection equipment, each having a work period of <12 years and age <37 years respectively. It is also known that work period and age of workers have a Sig (0.115)> α (0.05) and Sig (0.430)> α (0.05) accordingly, which means there is no relationship between work period and the age of the workers with the compliance with the use of ear protection equipment. Conclusion: The reasons of the non-compliance of workers with the use of ear protection equipment are they feel uncomfortable, they have a lack of supervision, as well as they have a lack of motivation work.age, animal feed, compliance, ear protection equipment, years of service

The United Kingdom’s response to the 2014-2018 Islamic State Terrorist Group attacks
Authors: Juita Dewi Nawar Sri
Published: March 2021

Advancements in technology, information, and communication have transformed warfare from a conventional method to psychological warfare (psywar). In the past, warfare was heavily associated with various weapons, such as rifles, bombs, or even nuclear power, to attack an area for specific purposes. In the modern era, warfare is more concerned about technology and information superiority to threaten the enemy faster and more robust. Modern warfare targets the psychology of society in order to win the war. Islamic State (IS) has attracted the world’s attention for its successful strategy in using Twitter in waging war on a country, in this case, the United Kingdom. The purpose of this research is to describe the United Kingdom government’s response in fighting Islamic State attacks on Twitter. This research uses descriptive methods by collecting data from books, the internet, journals, and scientific articles. This study indicates that the United Kingdom responds to Islamic State attacks through two patterns, hard and soft power. The hard power method is carried out through intelligence, police, and economic power to collaborate with international organizations such as the United Nations. The soft power pattern was implemented by creating official state Twitter accounts such as @UKAgainstDaesh, @coalition, @TerrorismPolice, and collaboration with the Global Internet Forum Counter-Terrorism (GIFCT). This strategy plays an essential role in stopping the spread of online terrorism-related content online by blocking related photos, videos, and texts of terrorism.

Emotionalization and Privatization of Political Communication on Facebook
Authors: Vučković Milica , Oblak Črnič Tanja
Published: March 2021

Social media are usually accused of being one of the major forces for personalization of ‏political communication and consequently for depolitization of recent politics. However, personalization ‏seems to stimulate certain users to pay more attention to political issues and to act more responsively to ‏such highly personalized political profiles. This article presents the results of a longitudinal analysis of ‏online presence of Barack Obama to assess his political communication through Facebook. It also answers ‏if presence of emotional appeals and private life cues in the posts have any effect on users’ responses in‏ terms of numbers of their likes, comments and shares. Based on a quantitative analysis of 2804 Facebook ‏posts, published in the period from 2008 to 2016, the results of content analysis revealed that Obama ‏used his Facebook fan page almost exclusively to communicate about political issues instead of his ‏personal life. The analysis also confirmed that a smaller number of posts, which contained emotional ‏appeals or cues from private life had significantly higher numbers of users’ responses than posts that ‏were not emotionalized or privatized. While personalization of Obama’s political figure is part of a wider‏ debate, this study confirms that the presence of private cues and emotional appeals stimulates greater‏ responsiveness from Facebook users.
Generation Z and Consumption

Published: March 2021

Using smart applications, members of Generation Z communicate in their networks on a wide‏ range of issues, which forms their social sensitivity and makes impact on their consumption. The article‏ focuses on Generation Z in Central and East Europe (CEE) where youth as a share of the total population is‏ the smallest in the world. This study investigates Generation Z in Lithuania, one of the CEE countries, and‏ presents the results of a large-scale survey of youth which analyses the expression of consumption and‏ its interconnection with characteristics formed by social media. There are three main characteristics that‏ explain consumption by Generation Z: cultural tolerance, social tolerance and tolerance to otherness on‏ the network. This threefold theoretical model was proved using the Structural Equation Model (SQM). On‏ the basis of this test we found out that social mindset is the strongest mediator between communication‏ environment and consumption by Generation Z. At the same time, communication environment‏ motivates for self-reward and hedonic consumption which does not compete and goes along with the‏ social mindset. We conclude that Gen Z is a new group in consumer society that is distinctive by its unique‏ characteristics.

Published: March 2021

U 21. stoljeću feministički pokret doživljava novi uzlet, a na to osobit utjecaj imaju slavne‏ žene koje svojim djelovanjem promoviraju emancipaciju žene. Cilj ovog rada bio je utvrditi kako se u‏ reklamama za ženske parfeme prikazuje emancipiranost kao poželjna ženska osobina. Kvalitativnom‏ istraživačkom metodom analize narativa analizirano je pet reklama za parfeme čije su glavne protagonistice‏ slavne osobe. Njihove zajedničke karakteristike su odlučnost, s izraženim osjećajem samosvijesti,‏ i buntovnost. One su ekstrovertirane, asertivne i sklone traženju uzbuđenja, kompetentne i orijentirane‏ na uspjeh. Njihova poželjnost određena je istodobnim utjelovljivanjem muževnog ponašanja i estetike‏ ženstvenosti, odbacivanjem rodnih normi (izuzev ideala vitkosti), dominantnim ponašanjem u interakciji‏ s muškarcima te okretanjem budućnosti. Ponašanje protagonistica izrazito odgovara karakteristikama‏ postfeminističkog poimanja ženstvenosti te podržava temeljnu odrednicu feminizma – ideju‏ emancipacije.

Main SEP measures presented in these studies were education, income, perceived socioeconomic status and employment. Sample size in these studies varied from N = 90 participants until N = 33865 participants. Overall, a lower educational level, a lower income and full-time employment were associated with EDS. EDS symptoms are prevalent in women, especially those with a low income or no job; and children and adolescents with difficult living conditions or people working part-time reported more sleep disturbances. Conclusions: SEP is already considered as an important determinant for many health outcomes, but if SEP is embedded in experimental design in psychosomatic research, biomedical research and clinical practice as a constant variable regardless of outcome; it will move forward future investigations.
