The switched varactor for high power RF signals is described in this article. This varactor can perform tuneable capacitor operations up to 10 GHz frequencies. The RF micro-electro-mechanical systems (MEMS) has become an atractive area of research in the recent. Devices like tuners, antenna beam forming networks and reconfigurable filters all will benefit from this.

optimal location placement power system distributed generation gams code matlab code

Distributed Generation (DG) is growing rapidly in power systems due to their potential solution for issues, like the deregulation in power system, to meet the power demand and the shortage of transmission capacities. Optimal placement of DG assumes significance that improper allocation of DG sources in power system would not only lead to increased power or energy losses, but can also jeopardize the system operation. Also optimal placement of DG is necessary fo ....etc

Toward Broadcast Reliability in Mobile Ad Hoc Networks with Double Coverage. (A New TCP for Persistent Packet Reordering).

Abstract:

The broadcast operation, as a fundamental service in mobile ad hoc networks (MANETs), is prone to the broadcast storm problem if forwarding nodes are not carefully designated. The objective of reducing broadcast redundancy while still providing high delivery ratio under high transmission error rate is a major challenge in MANETs. In this paper, we propose a simple broadcast algorithm, ca ....etc

Power System Reliability Analysis with Distributed Generators



Introduction

The economic and social effects of loss of electric service have
significant impacts on both the utility supplying electric energy and the end
users of electric service. The cost of a major power outage confined to one
state can be on the order of tens of millions of dollars. If a major power
outage affects multiple states, then the cost can exceed 100 million dollars.
The power system is vulnerable ....etc

IMPROVING RELIABILITY AND PERFORMANCE OF TRANSMISSION LINE USING FACTS TECHNOLOGY


INTRODUCTION :-
As generation and consumption of electricity has grown, investment in the transmission infrastructure has declined. The grid is aging and few new lines are being built, given high cost and permitting delays. The inability to control power flow on the grid results in poor asset utilization and impedes the growth of the energy market. Uncertainties in transmission investment recove ....etc

Optimal Placement of Distributed Generation on
Distribution Networks

ABSTRACT
In this paper we evaluate a heuristic methodology to obtain the optimal placement and size of distributed generation in order to minimize the distribution utility's cost. Technical aspects like energy losses and voltage levels are considered, as well as economic aspects like price of energy, investment and operating cost of distributed generation and cost of losses. ....etc

RELIABILITY IN MEMS PACKAGING

ABSTRACT
Cost effective packaging and robust reliability are two critical factors for successful commercialization of MEMS and microsystems. While packaging contributes to the effective production cost of MEMS devices, reliability addresses consumer s confidence in and expectation on sustainable performance of the products. There are a number of factors that contribute to the reliability of MEMS; packaging, in par ....etc
