A media storage and access system and methodology including a set-top box which receives and processes a plurality of signal sources and makes programming available locally through connected devices or via a data network such as a LAN, WAN, or the Internet. 5, and at least four light-sensitive layers, after development processing, being colored with color materials having different spectral absorption waveforms. The query is transformed into a set program having at least one operation structure, corresponding to the operator and having logic for type-independently performing an operation, corresponding to the operator, and having a data relation structure, cooperating with the operation structure, for handling all data access and storage associated with the operation. It is ensured that the opening degree of the expansion valve is automatically adjusted to the actual operating conditions, thereby optimising the efficiency of the vapour compression system. In addition, they can bond adherends by contact bonding despite that they are water-based solid adhesives. The patterns of behavior as well as the user preferences derived therefrom can then be used to apply individually adapted optimization criteria to the specific user in calculating the route.
