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 algorith ....etc

Abstract –
There is a trend toward increasing the performanceof power electronics converters used in photovoltaic systems.However, parameters such as reliability, efficiency, andcomplexity might be in conflict. In this paper, the design of asimple DC/DC interleaved boost converter is assessed. It takesadvantage of state-of-the-art power devices that have fastswitching times. It is shown that requirements of low complexity,high reliability, and high efficiency can be satisfied, withoutresorting to switching aids, provided that the dev ....etc

The performance of caching systems in general, and Internet caches in particular, is evaluated by means of the user-perceived service speed, reliability of downloaded content, and system scalability. In this dissertation, we focus on optimizing the speed of service, as well as on evaluating the reliability and quality of data sent to users. In order to optimize the service speed, we seek optimal replacement policies in the first part of the dissertation, as it is well known that download delays are a direct product of document availability at ....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 ....etc

Management of Available Power in Substation Transformers Based on Reliability
A method for estimating the maximum power obtainable from a distribution transformer is described in this article. This estimate is made on the basis of the estimated value of the future load, current temperature values measured at different points and also the factor of transformer reliability. Also developed is a system to provide means of controlling the transformer overload especially in the times of peak load.

System description
It consists ....etc

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.

Design principles
In the case of RF MEMS which depend on the electrostatic actuation have a a small air gap in the micrometer range between their movable membrane and ....etc
