Ev Charging

Electrical vehicles are the future of the world; hence, there is a necessity to pave the way for the upcoming technology and to ensure its contribution to the society fairly. Nevertheless, if the EVs completely replaced the fuel-based cars, more EV charging stations would be needed which might develop overconsumption of the main grid power causing remarkable instability. Consequently, the micro grids become the solution to this problem, in which they are defined as relatively small networks of energy sources and loads at the distribution level that aim to provide electricity to remote locations where the charging stations are located. In this chapter, the EV is considered as a load to the micro grid indirectly through the EV charging stations. Thus, micro grid loads will be retrieved from experimental data of an actual prototype electric vehicle to reflect on the battery degradation in a micro-grid connected system.

In less than three decades, Nokia emerged from Finland to lead the mobile phone revolution. It grew to have one of the most recognizable and valuable brands in the world and then fell into decline, leading to the sale of its mobile phone business to Microsoft. This book explores and analyzes that journey and distills observations and lessons for anyone keen to understand what drove Nokia’s amazing success and sudden downfall. It is tempting to lay the blame for Nokia’s demise at the doors of Apple, Google, and Samsung, but this would be to ignore one very important fact: Nokia had begun to collapse from within well before any of these companies entered the mobile communications market, and this makes Nokia’s story all the more interesting. Observing from the position of privileged outsiders (with access to Nokia’s senior managers over the last twenty years and a more recent, concerted research agenda), this book describes and analyzes the various stages in Nokia’s journey. This is an inside story: one of leaders making strategic and organizational decisions, of their behavior and interactions, and of how they succeeded and failed to inspire and engage their employees. Perhaps most intriguingly, it is a story that opens the proverbial “black box” of why and how things actually happen at the top of organizations. Why did things fall apart? To what extent were avoidable mistakes made? Did the world around Nokia change too fast for it to adapt? Did Nokia’s success contain the seeds of its failure?

<span lang="EN-US">Battery charging is an important issue when it is associated with battery life and cycle performance. The aim of this research is to design and promote fast battery chargers using fuzzy logic control techniques (FLC) for LiFePO4 batteries have been developed. The proposed charger is controlled by voltage and current to activate the PWM duty. The results show that the proposed battery charger has the potential to accelerate charging up to 37% at the rate when charging 2C. This means it is faster than the existing filling. The charger proposed by the FLC method is also capable of charging LiFePO4 batteries with greater efficiency, which is 82%. It can be concluded that the FLC application method has better performance than the CC-CV method</span>

With more than 500 million subscribers, India is the second largest mobile phone market in the world after China. In the last decade, an average of 15 Telecom operators has started operations in India. The market has been flamboyant for Indian as well as Foreign investors. Many of them are entering through the Merger and Acquisition route. The Governing Regulatory Authorities have a responsibility that no irregularity occurs and that every investor is given equal opportunity. Spectrum which is a constrained essential input for mobile services is also highly fragmented leading to possible industry inefficiencies. This paper critically examines the Merger and Acquisition scenario in the Telecom industry in India and the current policy framework that provides policy prescriptions for the future.

Aim: Prevalence and determining factors of refractive errors among the medical students in FMU, Faisalabad. Methodology: Cross-sectional quantitative study conducted in Faisalabad Medical University from 01-03-2020 to 15-12-2020 after approval from institutional review committee. All students of MBBS in FMU were included in this study. A structured questionnaire was used to collect the required quantitative information. SPSS version 26 was used for analysis. Results: Prevalence of refractive error is 49%. Females were 59% and males were 41%. More students i.e. 85.2% were suffering from myopia. In our study, usage of electronic devices i.e. mobile phones especially was one of the risk factors in developing refractive errors. 20.6% students having refractive error said that they use mobile phone for 4 hours, 30.2% having refractive error said that they watch TV for one hour, 23.3% having refractive error said that they play video games for one hour. For the correction of the refractive error, 184 students i.e. 97.4% used spectacles whereas only 5 (2.6%) students used contact lenses. It is observed in this study that contact lenses were only used by those students having refractive error <1.5. Conclusion: Refractive errors were a significant cause of visual impairment among medical students. The prolonged use of electronic devices especially mobile phones should be discouraged. Keywords: Refractive errors, myopia, electronic devices, mobile phone

The World

Participants in varying but recent citizen-led social movements in Kenya, Iran, Tunisia, and Egypt have found new voices by employing new ICTs. In some cases, new ICTs were used to mobilize citizens to join and/or to encourage use of violence against other ethnicities. In nearly all cases, the combined use of new ICTs kept the world informed of developments as ensuing protests progressed. In most cases, the use of new ICTs as alternative media motivated international actors’ intervention in averting or resolving ensuing crises. Foregoing engagements have also induced state actions such as appropriation of Internet and mobile phone SMS for counter-protest message dissemination and/or termination of citizens’ access. Against the background of the sociology and politics of social movements and a focus on the protests in Kenya and Egypt, this chapter broaches critical questions about recent social movements and processes: to what extent have the uses of new ICTs served as alternative platforms for positive citizens’ communication? When is use of new ICTs convertible into “weapons of mass destruction”? When does state repression or take-over of ICTs constitute security measures, and when is such action censorship? In the process, the chapter appraises the roles of local and international third parties to the engagement while underscoring conceptual definitions whose usage in studies of this kind should be conscientiously employed. Authors offer suggestions for future investigations.
