This book offers a timely review of modern technologies for health, with a special emphasis on wireless and wearable technologies, GIS tools and machine learning methods for managing the impacts of pandemics. It describes new strategies for forecasting evolution of pandemics, optimizing contract tracing, and for detection and diagnosis of diseases, among others. Written by researchers and professionals with different backgrounds, this book offers a extensive information and a source of inspiration for physiologists, engineers, IT scientists and policy makers in the health and technology sector.

The COVID-19 global pandemic has triggered health insecurity, food insecurity, and economic insecurity among many others in South Asia. It has profound impact on every sector of human activities ranging from the economic to environment. There is a need for a critical study of the implications of the COVID-19 pandemic for human security in order to fathom the emerging theoretical and policy issues in the region. Hence, the book provides an understanding of the consequences of the COVID-19 global pandemic for human security in South Asia. This intellectually stimulating book provides a critical analysis and insights on this contemporary challenge to policy makers, health professionals, academics, students, researchers, NGO workers working with health, human security and anyone interested in health and human security in South Asia. The book covers major human security areas, i.e. health security, food security, economic security, and environment issue. The role of regional cooperation and global health governance is also covered in the domain of COVID-19. This book fills the existing knowledge gap on the human security in South Asia in general and linking with COVID-19 in particular. From the perspective of policy, the insights of the study would guide the policy makers in South Asia in reframing their security policies emphasising human security issues and challenges. Finally, this book contributes to the evolving debate and discourse on the impact of the COVID-19 on the South Asian region from a human security perspective.

This stimulating book examines the key issues - including border management, water cooperation, and connectivity - challenges and possibilities in Bangladesh-India relations in the last fifty years. The book also investigates the role of the 'China factor', the role of civil society in Bangladesh-India relations and maps out the future course of actions in Bangladesh-India partnership in the post-pandemic world. The book contributes to both from theoretical and policy perspective and therefore will be immensely useful to the students of International Relations, Political Science, to academics, researchers, and policymakers with interest on Bangladesh-India relations, Bangladesh foreign policy, India's foreign policy in particular, and South Asia in general.

A Solar Home System includes Solar PV, battery, and solar charge controller. In most cases solar energy consumer use solar energy at evening hours, but it is available in day time. So, it is required to store solar energy into battery. A solar charge controller, or charge regulator is similar to the voltage regulator. It regulates the voltage and current coming from the solar panels and goes to the battery. Most of the batteries are fully charged at 14 to 14.5 volts. On the other hand, battery's life time drastically reduces due to the discharge over the level of 70%-80% DOD; at this discharge level the battery voltage normally goes down to 11.5 0.2 volts. Each battery has certain limit of capacity. Battery lifetime reduces due to overcharging and deep discharging. As battery is a very expensive component of Solar Home System. So, it is essential to protect the batteries from over charging and deep discharging. In this case charge controller plays a vital role to protect this battery. The research aims to study the design and implementation of a low cost solar charge controller."
