Abstract: A method for the production of blow-molded containers that are sterile at least in certain regions, and a blow-molding machine configured to carry out the method. In accordance with the method, blowing stations are arranged on a rotating blowing wheel. A preform of a thermoplastic material is first heated and then stretched in a blowing station by a stretching rod and subjected to a pressurized blowing fluid via a blowing nozzle.

The method and system enables the dynamic replication of data objects to respond to fluctuating user demand. The method and system is particularly useful in file servers such as multimedia servers delivering continuously in real time large multimedia files such as movies.

Abstract: An improved method for supporting an empirical measurement of the data bandwidth that one or more computer disks can continuously sustain while reading data. In a computer system having predetermined workload requirements and disk storage for storing an allocation table including entries for meta blocks and data blocks, a method for supporting a dynamic measurement of the read bandwidth of a disk, includes the steps of: creating an alternate allocation table that ignores the existing content of the disk; creating meta blocks for a phantom file by allocating the meta blocks from the allocation table; allocating data blocks for the phantom file from the alternate allocation table; and writing only meta blocks to the disk, but not actual data blocks. Since the actual data blocks are by far the largest component of the files, phantom files require only a very small number of disk blocks, and can be written very quickly.
