Provided is a turbine blade including: a platform; a blade body including a cooling flow channel including a meandering serpentine cooling flow channel; a fillet portion provided in a joint surface between the blade body and the platform; and a base portion including a cooling flow channel communicated with the serpentine cooling flow channel. According to the invention, the data storage medium is designed such that data which is used more than once for a calculation process is scrambled using different functions. This permits the user to generate expense line entries more in alignment with the locationway that many expense are actually generated, e. Respective third storage values are re-read from a subset of the memory cells that includes the memory cells holding the suspect storage values.
