Internet Protocol (IP) Telephony has many issues that have to be overcome before it can be considered a rival to the existing telephony infrastructure. One such issue is the quality of service. The use of play-out buffering at the receiver helps to improve the quality of Voice over IP (VoIP). A buffering algorithm has been proposed by Narbutt, which uses a dynamic approach to buffering. This algorithm is adjusted automatically according to an estimate of the network delay. This is more suitable to the changing network conditions usually experi ....etc

Please help me to interface rishabh energy meter EM 1340 with Arduino Uno. I have tried using ModbusMaster Library and SimpleModbus Library for coding in arduino. I have build RS485 to TTL converter using MAX485 IC and circuit which is given in SimpleModbus Library . I can share the code with you . My problem is that i am always getting Timeout Error . I checked on DSO the query at the converter end is not what is accepted , I mean when arduino sends query the message in form of square wave but at converter end their is loading . Please tell me ....etc

ABSTRACT




In the real world, many people are using online auctions for their easy business, which is a marvelous thing. The objective of this project is to implement an ËœOpen Cry Auction Serverâ„¢, which is application software for online auction transactions. It is a web application and has a database server for storing and retrieving data entered during the time of online transactions like buying and selling the items. This report describes the software architecture and describes the various processes that comprise the auction ....etc

I am using UART for communicating 8 modules having LPC2148 microcontroller as a slave with another module having LPC2148 as master.But I am finding a constraint of wire length(I have read some articles on net which suggest a wire length of 2.6 mtrs for a baudrate of 56000bps) Can I replace this with MODBUS communication ?If yes where can I get information about modbus? ....etc

Abstract
A computer cluster is a group of loosely coupled computers that work together closely so that in many respects it can be viewed as though it were a single computer. Clusters are commonly connected through fast local area networks and are usually deployed to improve speed and/or reliability over that provided by a single computer, while typically being much more cost-effective than single computers of comparable speed or reliability. Clusters built from open source software, particularly based on the GNU/Linux operating system, are in ....etc
