GPS and Remote Sensing for Emergency Vehicle Navigation and Communication

Organizations and individuals have been facing disasters globally and locally since hundreds of years. Increasing number of natural disasters has demonstrated the paramount importance of the natural hazards subject for the protection of environment and the citizens. Now more than ever, designing an efficient traffic system, moving vast amounts of helping goods quickly and safely across great distances is one of our most pressing needs. Satellite navigation systems are changing the way in which we travel from place to place whether by land, sea or air and whether in remote areas or through congested city streets. Global positioning system (GPS) and its role in advanced transportation projects is inseparable and become a synonym. The management and operations of vehicles and giving real-time information to users that will lead to cost-effective and satisfied service to passengers is possible nowadays using a GPS based vehicle navigation system and communication via remote sensing. This paper describes how the already developed fleet management and remote sensing technologies can be merged together to form an efficient disaster management system

Smart Power Transmission System Using FACTS Device

Received Oct 12, 2012 Revised Mar 24, 2013 Accepted Apr 8, 2013 Making of smart grids puts mounting pressure on the nation’s aging electric power transmission system. Just planting additional towers and stringing more line won’t practice the nation’s electric power transmission infrastructure to meet up the energy challenges ahead. Smart grids stand geared up to play a much larger role in the energy equation for reduction of transmission line losses with the range of technologies and methodologies now on hand. The FACTS controllers come out with the capability of enhancing transmission system control, reliability, and operation. Shunt Flexible AC Transmission Systems (FACTS) devices have been used in power systems since the 1970s for the improvement of its dynamic performance. This paper will discuss and express how Static Synchronous Compensator (STATCOM) has effectively been applied to power system for efficiently regulating system voltage and thus increase system load ability. This paper investigates the effects of (STATCOM) on voltage stability of a power system at different positions. STATCOM plays an important role in controlling the reactive power flow to the power network, when it is placed in a long transmission line. The simulation analysis of this paper can be used as guideline for power industry. The study is thereby simulated using the MATLAB/SIMULINK software and simulation results show that STATCOM is effective in midpoint voltage regulation on transmission line. In this paper comparison is also performed between STATCOM and SVC under fault condition and it is proved that STATCOM have the capacity to provide more capacitive power for the period of a fault than SVC. It is also displayed that STATCOM shows faster response than SVC. Keyword:

Swarm Intelligence Based Reputation Model for Open Multi Agent Systems

In open multiagent systems individual components act in an autonomous and uncertain manner, thus making it difficult for the participating agents to interact with one another in a reliable environment. A reputation model can however predict the behavior of the agents and can optimize the issues related with dynamism. In this paper we present a critical analysis of an existing model for open MAS (FIRE) against our proposed swarm intelligence based reputation model. The model not only provides an optimum solution to various issues of reputation but also provides the mechanism of getting information from various sources.
