  • In writing this book the author has been primarily concerned with the presentation of the basic essentials of power-system operation and analysis to students in the final year of first degree courses at universities and colleges of technology. The emphasis is on the consideration of the system as a whole rather than on the engineering details of its constituents, and the treatment presented is aimed at practical conditions and situations rather than theoretical nicety.

  • The whole world is in the grip of energy crisis and the pollution manifesting itself in the spiraling cost of energy and uncomforted due to increase in pollution as well as the depletion of conventional energy resources and increasing curve of pollution elements. To meet these challenges one way is to check growing energy demand but that would show down the economic growth as first step and to develop nonpolluting energy conversion system as second step. It is commonly accepted that the standard of living increases with increasing energy consumption per capita.

  • This book provides an introduction to contemporary constitutional law for intelligent readers who are not, or not yet, lawyers. It is a reasonably short book, which leaves out much detail. I have also done my best to write it in plain language – or at least to explain the jargon used by courts and lawyers before employing it myself. But the book does not talk down to the reader or omit central considerations.

  • There have been considerable changes in today’s power systems in recent years, due, in large part, to the emergence of competition and deregulation in power industries. The goal of deregulation is to provide the customer with reduced costs. The global competition between utilities leads to utility cost-cutting, downsizing, and reducing maintenance on both transmission and distribution systems. Power systems that are hierarchically integrated

  • The influence of temperature and the type of expander on the cycle life of negative lead±acid battery plates set to cycling tests following the requirements of the ECE-15 test protocol has been investigated. The plates prepared with the currently used expanders Vanisperse (Vs) or Indulin (In) alone have a considerably shorter cycle life than negative plates produced with a blend of the two expanders.

  • Benefit-cost ratios of intervention to control or prevent air pollution from household SFU will depend on what benefits and costs are included in the analysis and how non-market benefits and costs are valued. Health effects of air pollution are often a major concern and motivation for intervention. Which health effects to include and how they are valued are therefore an important consideration in an economic analysis. Large scale household stove programs have also been motivated by natural resource considerations, for instance in China in the 1980s.

  • As carriers begin deploying FTTX architectures, they are focusing a lot of attention on the outside plant (OSP) segment. And why not? This architecture presents many challenges with passive optical networking (PON) technology, thousands of distribution lines and connections, power and distance concerns, and so many other issues to address. Basically, the mindset is that if a problem is going to surface during the FTTX deployment, it will likely happen downstream.

  • Administrative law is an exciting topic, in particular for those with an interest in how the law seeks to control the exercise of the enormous powers of the modern state. In the development of the law generally, modern administrative law is a recent, very largely post-Second World War, phenomenon. In legal education, it has grown over the past 20 years from being a component within established constitutional law courses to being a subject in its own right. Its relationship with constitutional law, however, must not be forgotten....

  • Piezoelectric materials form the backbone of several components utilized in communication systems, defense systems, industrial automation, medical diagnostics, energy storage and harvesting, and information technology. In high performance piezoelectric applications the material of choice is based upon lead-based composition with Pb(Zr,Ti)O3 (PZT) being the base. Recently worldwide environmental considerations are demanding the elimination of lead-based materials from all the consumer items. This has created urgency for finding alternative to PZT.
