This research deals with generating warm water for these conditions using improvised photovoltaic (PV) panels. PV panels have the ability of concentrating the heat due to the incident solar insolation thereby increasing its temperature much above the ambient temperature. The efficiency of PV panels is also a function of temperature with an optimum performance temperature limited to 25 o C. Efficiency decreases by 0.5%/K after 25oC.The surface temperature of the PV panel increases due to concentration of heat, attaining 50-60 o C above 25 o C. This research articulates modelling of integrated hybrid Photovoltaic-Thermal (PV-T) system utilizing diethyl ether for generating warm water with simultaneous cooling of PV panels thereby increasing its efficiency. This objective was addressed with a heat exchanger in a cubical enclosure made of aluminium with solar cells occupying its top surface and acting as a heat input. The enclosure consist of ether as a heat storage and transmitting medium with circulating water inside the pipes as heat absorber. Ether was selected due to its boiling point of 34°C which would be able to transfer heat to the water until water attains a temperature of 34°C. Ether proved to be a viable option with 4.9°C reduction in surface temperature of the panels and also generating warm water at 34°C.","PeriodicalId":302312,"journal":{"name":"International Journal of Technical Research & Science","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133693868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract-Power system is a huge network which involves many operations going on at the same time. Hence, it is very complex. This complexity is susceptible to many abnormal conditions which may give rise to the low frequency oscillations causing instability in the operation. These low frequency oscillation ranges from 0.1Hz to 2Hz. It is most commonly addressed via incorporating Power System Stabilizer (PSS) in the system. But the elimination of oscillations by it may not be sufficient if the oscillations are due to the severe fault condition. In such a case, Flexible AC Transmission devices (FACTs) come to the aid consisting of several useful characteristics depending upon the type of device used. For the present work, use of Static Synchronous Compensator (STATCOM) has been made. Here, a structure has been designed in cooperating PSS and damping controller based on STATCOM for the purpose of damping out low frequency oscillations. STATCOM is added as the supplementary damping controller. The capability of structure is further enhanced by the use of JAYA Algorithm (JA) by optimizing its parameters. This developed optimized structure is then implemented in the Single Machine Infinite Bus System (SMIB) to analyze its performance. A two are four machine system has been developed and given design of PSS has been implemented for each of machines in their respective areas. To realize the whole model the platform was provided by the MATLAB/SMIULINK. Later on, the performance of the proposed structure for damping out controllers is compared with the other heuristic algorithm based controllers so as to show its vitality and robustness. The main focus which has been considered is the speed deviation at nominal, light and heavy loading conditions. The system modeled is tested for these loading conditions after deviation in speed with and without CPSS, and then with JAYA tuned coordinated design of CPSS and STATCOM. The results obtained have been tabulated and compared in different fault conditions with and without CPSS.","PeriodicalId":302312,"journal":{"name":"International Journal of Technical Research & Science","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124989615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main drawback is that the dc voltage generated by a single fuel cell varies from 0.7V to 1V. Due to the low input voltage in fuel cells, a suitable power conditioner is required to interface to the utility grid or local loads. To meet this requirement, this paper presents the design, development and performance of an inverter. The advantage of the proposed topology is that the modulation, control and protection requirements of each bridge are modular and it requires only a single dc source in each phase leg. A two-level Hbridge inverter using SPWM wave carrier modulation technique has been studied for total harmonic distortion (THD) and switching losses for fuel cell applications. A detailed study of the technique was carried out through MATLAB/SIMULINK for switching losses and THD. The results were verified through simulation.","PeriodicalId":302312,"journal":{"name":"International Journal of Technical Research & Science","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127437210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main goal or the philosophy behind this paper is to assess the impact of WhatsApp usage on student academic performance. The paper reviewed enormous works on the research topic in order to make a position on how far WhatsApp has impacted on academic performance. The model adapted in the work indicated a clear relationship between WhatsApp and academic performance. The research methodology was essentially exploratory and therefore depended on secondary data for the examination of issues surrounding WhasApp and academic performance. Content analysis was used to make analysis. The researchers found out that evolution of ICT in the world has led to uncountable effects on education, especially on academic performance. People use social WhatsApp to pass time, for entertainment and learning at large. Many people get socialized through the use of WhatsApp. This avails them the opportunity to share pictures, academic videos, group/class interaction and other vital academic materials online. Also most students tend to spend time on WhatsApp than academic activities. Researches also indicated poor academic communication among students while writing examination. This to us will greatly affect the human capital development on the long run leading to half-baked and unproductive graduates. The researchers therefore, advice that strict rules and regulations should be made to that effect by the various educational institutions towards eliminating this abnormality.","PeriodicalId":302312,"journal":{"name":"International Journal of Technical Research & Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128614243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heat treatment process such as normalizing is often required to be done on raw material to soften the materials and to relieve the stresses. However, if process parameters are not selected properly, the desirable mechanical properties of steel may not be achieved. The present investigation is an attempt to study the effect of the process parameters such as soaking time, temperature and iso-annealing temperature on the hardness of 16MnCr5 steel using Taguchi method. These were varied and resulting changes in material microstructure were observed. Further, hardness in the range of 160-210BHN and 190-260BHN was observed, with the non uniform distribution of ferrite and pearlite phases. Also, the surface of the samples was found to have coarse grains.","PeriodicalId":302312,"journal":{"name":"International Journal of Technical Research & Science","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133536877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
