High-availability power systems: Redundancy options

In major applications like major computer installations, process control in chemical plants, safety monitors, IC units of hospitals etc., even a temporary power failure may lead to large economic losses. For such critical loads, it is of paramount importance to use UPS systems.

But all UPS equipments should be completely de-energized for preventive maintenance at least once per year. This limits the availability of the power system. Now there a ....etc

Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz ....etc

Almost all firms use UPS systems. They maintain the continuity of supply in case of power outages. But all UPS equipments regardless of manufacturer should be completely de-energized for preventive maintenance at least once per year. This limits the availability of the power system.

But now a ?days certain configurations of the UPS systems are there to permit concurrent maintenance so that we can overcome the above problem.

Each of the system configurations described in this paper has its own advantages and disadva ....etc

Introduction

In major applications like major computer installations, process control in chemical plants, safety monitors, IC units of hospitals etc., even a temporary power failure may lead to large economic losses. For such critical loads, it is of paramount importance to use UPS systems.

But all UPS equipments should be completely de-energized for preventive maintenance at least once per year. This limits the availability of the power system. Now there are new UPS systems in the market to permit concurrent maintenance.

Aim: To create a distributed application to download various files from various servers using RMI
Algorithm:
1. Create four files – file interface, file implementation, file client and fileserver
2. In the file interface, class specify the prototype of the method that is to be implemented in the file implementation class
3. In the file implementation class, specify the implementation coding for the method defined earlier (download file)
4. Try to read the contents of a file in this class
5. In the fileclient class try t ....etc
