Methods for identifying array areas in dies formed on a wafer and methods for setting up such methods are provided. Delay information indicating a relationship between a calibration pattern to be received and an amount of cycle delay is stored in advance. Each hull node in the hull hierarchy stores parameters which characterize a bounding hull for the corresponding cluster or object. In another embodiment, a method comprises storing an interrupt state describing a virtual interrupt in a storage area allocated to a guest. The fiber has a core that is a polyolefin that is at least partially enveloped by a sheath that is a copolymer of an olefin and at least one olefinically unsaturated comonomer selected from the group consisting of an unsaturated carboxylic acid, alkyl acrylate, alkyl methacrylate and vinyl ester. A vacuum pump is controllably connected via a suction line to the hollow chamber of the housing and to one of the storage compartments.
