Introduction

With the development of modern power system to the direction of extra-high voltage, large capacity, far distance transmission and application of advanced technologies the demand on the safety, stability and economic operation of power system became higher. A good grounding system is the fundamental insurance to keep the safe operation of the power system. The good grounding system should ensure the following:

To provide safety to personnel during normal and fault conditions by limiting step and touch potential.
To assur ....etc

Managing construction sites are difficult due to temporary work nature, changing work area, untrained workers, over time works etc., Most of the accidents occurred in construction activities like building structures, demolition, excavation, roof work, alteration, scaffolding, painting etc,. In typical construction works about 1500 people are killed in Britain and 25,000-30,000 more are seriously injured. The accident statistics represent not only serious human tragedies but also substantial economical losses due to accidents which cause damage ....etc

An automotive controller that complements the driving experience must work to avoid collisions, enforce a smooth trajectory, and deliver the vehicle to the intended destination as quickly as possible. Unfortunately, satisfying
these requirements with traditional methods proves intractable at best and forces us to consider biologically -inspired techniques like Swarm Intelligence.

A controller is currently being designed in a robot simulation program with the goal of implementing the system in real hardware to investigate these ....etc

Success is all about being in the right place at the right time ?.. and the axiom is a guiding principle for designers of motorsport circuits. To avoid problems you need know where and when things are likely to go wrong before cars turn a wheel -and anticipating accidents is a science.

Take barriers, for example .there is little point erecting them in the wrong place -but predicting the right place is a black art. The FIA has developed bespoke software, the Circuit and Safety Analysis System (CSAS), to predict problemareas on F ....etc

Seasonal Influence on Safety of Substation Grounding

Introduction
The low or high resistivity soil layer formed in raining or freezing season affects the safety of grounding system, and leads the changes of grounding resistance of the grounding system, step and touch voltages on the ground surface.

This paper systematically discusses the seasonal influence on the safety of grounding system and the different methods to be adopted inorder to nullify the effect of seasonal changes. Inorder to nullify the effect of the seasonal changes we c ....etc

This is the era of automobile revolution. People in old days looked for comfort luxury and economy, but now a day they are keener on safety. Safety places an important roll on the design and production of modern car. A lot of research and developments made in this field and hence a lot of safety devices are implemented on modern cars. In the two decades, automobile technology is evolved so much and, more and more safety systems have been incorporated into the car in an attempt to make them safer. Safety systems in automobiles are classified in ....etc
