A vehicle positioning apparatus and method are provided, which includes a magnetic source, a sensing unit, a signal process unit, and a display unit. The query and geographic location are incorporated into a message digest, which can be a hash. Solar energy in a wide range of sunlight spectrum can be efficiently converted into electric energy by moving electrons from the electron emitter to the electron collector. A latency for the runtime and the resource requirements for running in the multi-client environment are fed out as the result of simulating. The resource request specifies the resource and the virtual machine type, thereby enabling the resource server to retrieve the correct instance of the classfile to return to the resource loader.
