DIGITAL's Alpha 21264 processor is a highly out-of-order, superpipelined, superscalar implementation of the Alpha architecture, capable of a peak execution rate of six instructions per cycle and a sustainable rate of four per cycle. The 21264 also features a 500 MHz clock speed and a high-bandwidth system interface that channels up to 5.3 Gbytes/second of(More)
The Unified Modeling Language has become widely accepted as a standard in software development. Several tools have been produced to support UML model validation. However, most of them support either static or dynamic model checking; and no tools support to check both static and dynamic aspects of a UML model.

Use case diagrams in UML are used to give requirements for a software system, but all descriptions for each use case are written in informal(More)

Attempts to automate the sewing process of garment manufacturing have employed substitutes for human guidance of fabric into somewhat conventional sewing machines. A new approach has been proposed and partially verified in prototype form. It consists of several subsystems responsible for 1) gross fabric motion, 2) precision detection of the fabric location(More)
