Abstract
Two major factors that limit the throughput inmulti-hop wireless networks are the unreliability of wirelesstransmissions and co-channel interference. One promising techniquethat combats lossy wireless transmissions is opportunisticrouting (OR). OR involves multiple forwarding candidates torelay packets by taking advantage of the broadcast nature andspacial diversity of the wireless medium. Furthermore, recentadvances in multi-radio multi-channel transmission technologyallows more concurrent transmissions in the network, and sh ....etc

Introduction

Requirements for removable media storage devices (RMSDs) used with personal computers have changed significantly since the introduction of the floppy disk in 1971. At one time, desktop computers depended on floppy disks for all of their storage requirements. Even with the advent of multigigabyte hard drives, floppy disks and other RMSDs are still an integral part of most computer systems, providing.

Today, the World Wide Web is used for information, commerce, news, weather, music, telephony, audio and video conferencing, database access, file sharing, with new features cropping up almost daily. Each has its own security concerns and weaknesses. The frequency and sophistication of Internet attacks have increased. These changes in the Internet community and its security needs prompted the first bona fide defense measures. The network must be protected from outside attacks that could cause loss of information, breakdowns in network integrity ....etc

Multi-agent systems exhibit highly dynamic behaviour within dynamic environments. Modelling of individual agents within such systems demands considering both evolving data structures and the control over their internal changing states. In addition, modelling of the overall system implies modelling of the agents configuration, including their ability to exchange messages as well as the ability to re-structure their formation over time. This is particularly the case with biological multi-agent systems, such as colonies of ants or bees, flocks of ....etc

The present day requirement for high performance from a medium power engine has resulted in generally higher maximum crank shaft speeds, typically in the region 5500 ? 6000 rpm. This can be explained by recalling the factors governing the power output of an engine since, if neither piston displacement nor mean effective pressure can be further increased. Then the only other way to raise the maximum power is to permit higher crank shaft speeds. For this reason it becomes increasingly more important to avoid erratic operation of valves. As a resu ....etc

Abstract
With the increase of usage of wireless networks for purposes where the nodes are either stationary or minimally mobile, focus is also on increasing the network capacity of wireless networks. One such way is to use non-overlapping multiple channels provided by 802.11 by using multiple interfaces per node. Multiple nonoverlapped channels exist in the 2.4GHz and 5GHz spectrum. However, most IEEE 802.11-based multihop ad hoc networks today use only a single channel. As a result, these networks rarely can fully exploit the aggrega ....etc

Fluorescent Multi-layer Disc

The introduction of the Fluorescent Multi-layer Disc (FMD) smashes the barriers of existing data storage formats. Depending on the application and the market requirements, the first generation of 120mm (CD Sized) FMD ROM discs will hold 20 - 100 GigaBytes of pre -recorded data on 12 - 30 data layers with a total thickness of under 2mm.In comparison, a standard DVD disc holds just 4.7 gigabytes. With C3D's (Constellation 3D) proprietary parallel reading and writing techn ....etc
