 Abstract

The present research work deals with the control of grid frequency by controlling the operation of doubly fed induction generator and also control regulation of active power of demand and supplied by grid with help of doubly fed induction generator. The evolution of technology related to wind systems industry leaded to the development of a generation of variable speed wind turbines that present many advantages compared to the fixed speed wind turbines. These wind energy conversion systems are connected to the grid through Voltage Source Converters (VSC) to make variable speed operation possible. The studied system here is a variable speed wind generation system based on Doubly Fed Induction Generator (DFIG). The rotor side converter (RSC) usually provides active and reactive power control of the machine while the grid-side converter (GSC) keeps the voltage of the DC-link constant. The additional freedom of reactive power generation by the GSC is usually not used due to the fact that it is more preferable to do so using the RSC. This paper deals with the introduction of Doubly fed induction generator, AC/DC/AC converter control and finally the SIMULINK/MATLAB simulation for isolated Induction generator as well as for grid connected Doubly Fed Induction Generator and corresponding results and wave forms are displayed.

 Abstract

The present study covers the various aspects of biodiesels fuel derived from Karanja seed oil and also the study of performance and emissions on four stroke compression ignition engine. Crude Karanja seed oil is converted to Karanja seed oil methyl esters by transesterification process. The obtained biodiesel properties are measured experimentally and analyzed with diesel. The performance and emission parameters of biodiesel blends were compared with the diesel and from the result analysis the optimum Karanja seed oil blend is found. After finding optimum blend, the tests were conducted on the same engine with addition of DMC (Dimethyl carbonate) as a fuel additive at 5%, 10% and 15% on volume basis and evaluate its effects on diesel engine characteristics. The main purpose of fuel additives is to improve the combustion process and reductions of exhaust emissions. Finally, the experimental outcomes are analyzed with the diesel. The blend KSOME15 with DMC10% is shows better performance and lower emissions. Finally, results show the improvement in engine performance and reduction of emission parameters needs to justify the potentiality of the Karanja seed oil methyl ester as alternative fuel for diesel engine without any modification.

 Abstract

The journal studies this time will examine the differences in the way and pattern of government of the two Prime Ministers of Malaysia, namely between Tan Sri Dato '(DR) Haji Mahiaddin Bin Md Yasin where he became the 8th Prime Minister of Malaysia on 29 February 2020 and resigned on 16 August 2021 after another struggle in Malaysian politics and Tun Dr. Mahathir Bin Mohamad. The first time Tun Dr. Mahathir Bin Mohamad as a prime minister on 16 July 1981 until 30 October 2003 and the second on 10 May 2018 until he resigned on 24 February 2020. These two dates are in different eras. But we will study it more specifically in terms of socio-economics. The uniqueness of this study is because Tun Dr. Mahathir Bin Mohamad has been the Prime Minister of Malaysia twice and both in different eras. It is common knowledge that the political system in Malaysia is based on democracy. The top leadership is elected fairly and listens to the voices of all players in politics as well as the voices of the people. The goal of these two leaders is between Tan Sri Dato '(DR) Haji Mahiaddin Bin Md Yasin and Tun Dr. Mahathir Bin Mohamad is the same, which is to develop the country's economy and further maintain the well -being of the people while developing the country to be in line with other developed countries. However, the ideas and thoughts between these two leaders are definitely different in all aspects even though the goals are the same. That is the difference that will be described in this study.

 Abstract

Stress is a condition of mental pressure for particular individual facing problems from envi-ronmental and social well-being which leads to so many diseases. Young age is the critical period because at this time youth faces lots of changes in his/her life. They are expected to be the elites in the society. Thus, they should enhance their stress management abilities so as to live a healthy life after entering the society. When a child enters into the youth age, they need to not only adapt themselves to the new life and new environment but also be familiar with many new people, events, and things. The life stress on them is considerable. Therefore, understanding the sources of stress among them and how they can cope with the stress is very important. The researcher found that the stress mainly comes from academic tests, interpersonal relations, relationship problems, life changes, and career exploration. Such stress may usually cause psychological, physical, and behavioral problems. They should be brought up in the positive environment. More emphasis should be given to the outdoor activities and create hostile learning environment by minimizing the negative impact of stressors. The findings will help the individual students, scholars, lecturers, career and counseling centers.

 Abstract

Social media platform is the need of hour of every tourism industry,where everyone wants to connect with the entire travellers through this platform.Using S. M. P. creates win win situation for industry as well as travellers.The major agenda behind conducting this research investigation is to scrutinize and evaluating the consequences of social media practices on performance of tourism industry in the Uttarakhand state and providing some expedient recommendations regarding social media practices as well as guidelines of tourism industry. Research study is mixed in nature (quantitative and qualitative) and depends upon only primary sources of data collection: researchers has selected around 100 tourism marketers or industrialists of Uttarakhand (50 industrialists /marketers from dehradun, +50 industrialist /marketer from nainital) for study. Random sampling method has been implemented by the researchers.Three tables have been mentioned in respect of data analysis. Table 1 comprises of social media platforms adopted by tourism Industry of Uttarakhand, table 2 encompasses of time period from which they are operating their social media page and table 3 contains duration of the updation and posting of content to social media by industry. Table 4 includes the feedback of industrialist based on likert's 5 point scale. At the end, researchers has recorded some facts regarding social media which acts as a powerful weapon to attract so many traveller troops to avail and assess the services provided by tourism industry and how fake or false information posted by tourism industry ferociously affects the working of tourism industry, despite of having negatives highlighted by researchers in their paper, there is some glimmer of courage to exterminate the issues facing by tourism industry, that is as follows :-(I)every industry must utilize their social media platform to engross travellers meritoriously. (II) Govt. and cyber cell authorities should prudently supervise the social media pages of tourism industry in order fend off unfair practices

 Abstract

Domestic violence against women is a universal problem. It could broadly be defined as any act of gender-based violence that results in or is likely to result in physical, psychological or sexual harm or suffering to women including threats of such acts. It was recognised as a criminal violence in India in 1983 but most violence inside the homes goes unreported. Primarily because family and community structures render it difficult, if not impossible for women to report abusive husbands or in-laws, the verry people upon whom they are most dependent (Agnes, 1992). Though domestic violence against women is fairly common across all socio-economic and cultural/ caste configurations across India and is documented fairly extensively in the context of dowry related violence in the middle-class context, the specificity of violence faced by Dalit women in domestic space largely remains neglected in the activism and discourse around domestic violence due to several reasons. Despite clear indications from various surveys and sociological studies that prevalence of women facing domestic violence at physical and psychological level is much higher among Dalit women in comparison to other dominant caste women, it is often (wrongly) treated as insignificant issue in comparison to threat of or actual violence experienced by them in the public spaces.
