a pervasive computing environment can be expected based on the recent progresses and advances in computing and communication technologies. Next generation of mobile communication will include both popular infrastructured wireless networks and novel infrastructureless mobile ad-hoc networks (MANETs). A MANET is collection of wireless nodes that can dynamically form a network to exchange information without using any pre-existing fixed network infrastructure. Wireless ad-hoc networks are increasingly being used ....etc

Challenges in the Migration to 4G

Second-generation (2G) mobile systems were very successful in the previous decade. Their success prompted the development of third generation (3G) mobile systems. While 2G systems such as GSM, IS-95, and cdmaOne were designed to carry speech and low-bit-rate data, 3G systems were designed to provide higher-data-rate services. During the evolution from 2G to 3G, a range of wireless systems, including GPRS, IMT-2000, Bluetooth, WLAN, and HiperLAN, have been developed. All these systems were designed independen ....etc

A multi-scale model for electrochemistry in proton exchange membrane (PEM) fuel cells has been developed. The multi-scale model involves four scales: atomic-scale for kinetics of chemical/electrochemical reaction, nano-scale for surface reactions, micro-scale for electrolyte transport, and macro-scale. The energetics of chemical and electrochemical reactions are computed using quantum computation which serves as input for the kinetics on nano-scale catalysts which is simulated using the dynamic Monte Carlo (DMC) method. A full fuel cell model w ....etc

Introduction

According to the American Marketing Association, green marketing is the marketing of products that are presumed to be environmentally safe. Thus green marketing incorporates a broad range of activities, including product modification, changes to the production process, packaging changes, as well as modifying advertising. Yet defining green marketing is not a simple task where several meanings intersect and contradict each other; an example of this will be the existence of varying socia ....etc
