This book deals with development of computer multimedia software package for school children to enhance their academic achievement in Science, especially of low achievers in Physics. Science in school is meant to enable the child to think scientifically, analyze and to articulate logically. Physics is an important branch of Science which contains a number of abstract concepts. Physics generates fundamental knowledge needed for the future technological advances that will continue to drive economic engines of the world. Hence, the methods of teaching/learning science need to be...

The present book is written for those researchers who are interested in designing a low-cost, low- power Wireless Sensor Network (WSN). In this book, design and development of a low cost WSN node using MSP430 microcontroller and nRF24L01 radio transceiver has been given in detail. A new adaptive power algorithm has been developed, which further reduces the power consumption of this node. The evaluation of WSN node has been done for various tests including routing algorithms, packet loss measurement, receiver sensitivity and calculation of free space loss. A case study of Car Parking...
