A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services. First, a client directly connects to the proxy server, and makes a request for a file or any other resource available on a different server. The requested resource is provided by the proxy server either from the cache or by fetching from the specified server. In some cases, the client's request or the server's response maybe altered by the proxy server> the purpose for this maybe for vi ....etc

The method of finding the location of moving Automatic Guided Vehicles (AGV) in pre-defined areas is by Distance Measurement Equipment (DME) which is based on ultrasound and triangulation technique. To reduce error,the ultrasound transmitter needs to be within the line of sight of the receiver. To get rid of this problem, powerful transmitters are used to ensure omni-directional transmission over large distances, which results in cone-shaped propagation..The new system shows that the vehicle can be more flexible, and angular restrictio ....etc

In computer networks, a proxy server is a server (a computer system or an application program) which services the requests of its clients by forwarding requests to other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server provides the resource by connecting to the specified server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and ....etc
