Multicast Routing with Delay and Delay Variation Constraints for Collaborative Applications on Overlay Networks

Maximum variation in the delays from a source to the destinations. The time-complexity of our Algorithm is O ( E +nk log ( E /n) +m2 k), where n and E are the number of nodes and edges in the network, respectively, k is the Number of shortest paths determined, and Abstract Computer supported collaborative applications on overlay networks are gaining popularity among users who are geographically dispersed. E ....etc

Abstract
Computer supported collaborative applications on overlay networks are gaining popularity among users who are geographically dispersed. Examples of these kinds of applications include video-conferencing, distributed database replication, and online games. This type of application requires a multicasting subnetwork, using which messages should arrive at the destinations within a specified delay bound. These applications also require that destinations receive the message from the source at approximately the same time. The problem of fi ....etc

power amplifier circuit diagram



Circuit Description
There are many instances where a simple and reliable power amplifier is needed - rear and centre channel speakers for surround-sound, beefing up the PC speakers, low powered tweeter amplifier, etc. For those who want to build their own 'Gainclone' amplifier, this will certainly do the job :-)
This project (unlike most of the others, but in a similar vein to Project 19) is based almost directly on the typical application ci ....etc

Automatic temperature controlled fan
Here is a scheme through which the fan can be linearly thespeed controlledautomatically, dependingon the room temperature. The scheme is effective because it ishighly control thyristors forpower. Alternatively, samecircuit can be used to automatically control AC temperaturecontrolled.In this diagram, temperature NTC thermistor is sensorused, i.e. one Havinga multiplier negative temperatures. The resistance of the thermistor in Thevalue 25 with the isabout 1 kilogram-ohm.Op Amp A1 essentially works for ASI t ....etc

Common Emitter BJT Amplifier Design Current Mirror Design


Some Random Observations
Conditions for stabilized voltage source biasing
Emitter resistance, RE, is needed.
Base voltage source will have finite resistance, RB.
needs to be much larger than RB.
Small RB - relative to RS - will attenuate input signal.
Larger RE permits larger RB, but results in lower gain.
Gain = -RC/RE for RE >> re.
Split RE with bypassing increases gain.
Requires large bypass cap ....etc
