Long-Reach Optical Access Technologies

Abstract


A number of leading long-reach optical access technologies are examined. It gives the economic arguments behind the technologies.

1. Introduction


As broadband uptake increases globally, the services offered are becoming increasingly bandwidth-intensive. A service that continues to increase bandwidth requirements is high-definition television (HDTV), which requires in the region of 8 Mb/s per channel. For telecommunication networks to support a single channel of HDTV plus data and ....etc

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

Abstract
Project Title: Multi Threading Interactive Client Chat
Communication over Internet or Intranet has become a feature of everyday life in the 21st Century. It is in has evolved into a new medium of communication and developing itself into a register with identifiable elements and relatively stable characteristics.

This project is to create a chat application with a server and clients to enable the clients to chat with many other clients. This project is to simulate the multicast chatting. In the case of multicasting when a messag ....etc

Definition

Compact peripheral component interconnect (CPCI) is an adaptation of the peripheral component interconnect (PCI) specification for industrial computer applications requiring a smaller, more robust mechanical form factor than the one defined for the desktop. CompactPCI is an open standard supported by the PCI Industrial Computer Manufacturer's Group (PICMG). CompactPCI is best suited for small, high-speed industrial computing applications where transfers occur between a number of high-speed cards.

It is a high-performance indust ....etc

MULTI-THREADED SERVER CLIENT CHAT MODEL
AIM OF THE PROJECT: To design and implement a chat model which can perform many processes or tasks at same time with very low halting problem i.e. a Multi-Threaded Server Client Chat Model.

A set of devices (often referred to as nodes) connected by communication links makes up a network. A computer, printer, or any device that can handle data can be a node. developing networking applications is primarily based on socket programming. c, c++, Java etc. are widely used for this purpose.

Description : This is nothing but the Chat application. Each and every user should give the name before communicate each other. All the user names will be displayed in the current user list. One user can communicate with another user by select the name of the user. Whenever communicating with each other, they can send String data as well as files.
Technologies : Jsp,Java and Servlet
Back End : Access ....etc

I am doing a project in which i have to count the no.of. vehicles passing a signal in a particular lane. Which type of sensors can be used to count the vehicles...? If ir sensors can be used,is it possible to design ir transmitters and receivers in the range of 40 to 50 meters or more....? or Are they readily available in the market...? ....etc
