This book is focused on fabrication of composite material with powder metallurgy. It also includes the hardness test for finding the mechanical properties & machining operation for getting optimize MRR. With the help of SEM, EDS and hardness test Micro structure and properties were investigated to know effect of sintering temperature and time composite materials. The micrographs of Cu-graphite reflect the clean interface and good compatibility between matrix and reinforcement. The result showed that Cu- SiC composite is having more uniform structure visualized after the sintering, everywhere reinforcement material located in base material. Machining of fabricated composite Cu-SiC is more easy compare than other because it is having more material removal rate (MRR). The results obtained by this research will be useful for various Manufacturing Industries and researchers working in this field.

The main aim of this book is to analyze the effect of utilization of butanol and ethanol on emissions, exhaust temperature, power and efficiency, taken in definite quantities in spark ignition engine with gasoline. Due to concerning shortage of fossil fuels and there harmful effects on environment and human life has lead the world to think about an effective alternative to these, So we will try to reduce all these emissions from the gasoline engines. It is imminent that the petroleum reserve will be finished soon if some alternative fuels does not at least partly replaces petrol and diesel. It should have satisfactory brake power, thermal efficiency, low polluting emissions and should be long lasting and economical. Government has mandated the use of gasoline-ethanol blends in many countries. The Results obtained by this research will be useful for various Automobiles Industries and researchers working in this field.

This story is about an extraordinary journey of an ordinary Indian Immigrant to the UK. He grew up in a middle-class Indian family, had troubled childhood, struggling working life, and failed relationships. Despite all personal and professional setbacks, his desperation to keep moving forward in life, hunger for success and persistent hard work takes him to the level of success that most people can only dream to achieve. It's an amazing story of hope, courage, perseverance and how an ordinary middle-class Indian boy builds a bridge between his dreams and reality, to become one of the richest tycoons in England.

The last decade has witnessed an unprecedented development and growth in global wireless communications systems, technologies and network "traffic" generated over network infrastructures. This book presents state-of-the-art energy-efficient techniques, designs and implementations that pertain to wireless communication networks such as cellular networks, wireless local area networks (WLANs) and wireless ad hoc networks (WAHNs) including mobile ad hoc networks (MANETs), and wireless sensor networks (WSNs) as they are deployed across the world to facilitate "always on" reliable high-speed wireless access from anywhere, at anytime to accommodate the new paradigm of the "Internet of Things" (IoT). The pervasive and exponential growth of Wi-Fi and the impact of bandwidth-intensive applications on the energy consumption of Wi-Fi-enabled devices are discussed along with energy harvesting as an advantageous option to power WAHNs. The book aims to serve as a useful reference for researchers, students, regulatory authorities, and educators.
