To provide means for editing a content data stream quickly. Such method may be employed for real-time or off-line applications for electric power systems reliability assessment, and is capable of determining whether or not a physical solution to the load flow problem exists, or if the system is in a state of voltage collapse. The radiation source is arranged to project radiation having the first property onto the radiation converter thereby producing radiation having the second property, while the radiation converter is arranged to illuminate an object to be imaged by the imaging sensor with radiation having the second property. The application programs may store descriptors from which the protocol stack may form payload data for data units. A stacked structure of a gate oxide film and a gate electrode are formed on the active region to complete the formation process of the semiconductor device.
