  • Modeling the thermal-to-plasma transitions for Cu photoablation

    Publication Year: 1994, Page(s):3 - 10

    Excimer laser ablation of metals starts as a thermal process in the ∼1-J/cm2 fluence range and makes a rapid transition near 5 J/cm2 to a highly ionized plume (for 10-ns pulses). The 1-5-J/cm2 range is of particular interest because it overlaps the irradiance range used to fabricate high- temperature superconductors, diamondlike carbon films, and conducting ...

  • ABC: A better control for manufacturing

    Publication Year: 1994, Page(s):11 - 30

    ABC is a generic methodology to improve the quality of manufacturing. It can optimize operation of a single process or an entire factory to meet or exceed product specifications. ABC is based on three nets which continually interact to model processes and to provide local process control and global product optimization. Significant process variables are identified, evaluated, and ranked according ... View full abstract»

  • Embedding hyperpyramids into hypercubes

    Publication Year: 1994, Page(s):31 - 46

    A ̂P(k, d) hyperpyramid is a level structure of k hypercubes, where the hypercube at level i is of dimension id, and a node at level i - 1 is connected to every node in a d-dimensional subcube at level i, except for the leaf level k. Hyperpyramids contain pyramids as proper subgraphs. We show that a hyperpyramid P(k, d) can be embedded in a hypercube with minimal expansion and dilation = d.... View full abstract»

  • Background data movement in a log-structured disk subsystem

    Publication Year: 1994, Page(s):47 - 58

    The log-structured disk subsystem is a new concept for the use of disk storage whose future application has enormous potential. In such a subsystem, all writes are organized into a log, each entry of which is placed into the next available free storage. A directory indicates the physical location of each logical object (e.g., each file block or track image) as known to the processor originating th... View full abstract»

  • SCISM: A scalable compound instruction set machine

    Publication Year: 1994, Page(s):59 - 78

    In this paper we describe a machine organization suitable for RISC and CISC architectures. The proposed organization reduces hardware complexity in parallel instruction fetch and issue logic by minimizing possible increases in cycle time caused by parallel instruction issue decisions in the instruction buffer. Furthermore, it improves instruction-level parallelism by means of special features. The... View full abstract»
