A power dolly is disclosed having an elongated main frame and load bed with a pair of traction wheels at the front end and a pivot wheel at the rear end with a manual steering handle behind the pivot wheel. The outer layer sections include an outermost layer and a second layer inwardly located therefrom. A device includes at least one exhaust gas line through which an exhaust gas can flow in a flow direction, a nozzle for introducing a reducing agent containing or forming ammonia, and the aforementioned particle filter. Electric terminals for connection with separate power supply wires are also provided on the connection board exterior surface. In particular, a reversible inner function is used in a nested message authentication code configuration to provide both error detection and error correction in high performance applications. The method includes the steps of compiling a source code of the intermediate code-based application program to an intermediate code, translating the intermediate code to a PTX instruction code, and translating the PTX instruction code to a machine code executable by the target graphics processing unit before delivering the machine code to the target GPU.
