In this paper, we introduce the concept of dynamical distance on a nuclear conguration space. We partition the nuclear conguration space into disjoint classes. This classification coincides with the classical partitioning of molecular systems via the concept of conjugacy of dynamical systems. It gives a quantitative criterion to distinguish dierent molecular structures.

Speedups of coupled processor-FPGA systems over traditional microprocessor systems are limited by the cost of hardware reconguration. In this paper we compare several new con guration caching algorithms that reduce the latency of recon guration. We also present a cache replacement strategy for a 3-level hierarchy. Using the techniques we present, total latency for loading the con gurations is r...

This paper describes a framework and tools for automating the production of designs which can be partially recon gured at run time. The tools include: (i) a partial evaluator, which produces con guration les for a given design, where the number of con gurations can be minimised by a process known as compile-time sequencing; (ii) an incremental con guration calculator, which takes the output of ...

This paper outlines an appr oachand experimental results for Synthetic Aperture Radar (SAR) object recognition using the MSTAR data. With SAR scattering c enter locations and magnitudes as features, the invariance of these featur esis shown with obje ct articulation (e.g., rotation of a tank turr et) and with external con guration variants. This scatter er location and magnitude quasi-invarianc...

In this paper, we study distributed algorithms for nding the k-th value in the decentralized systems. First we consider the case of circular con guration of processors where no processor knows the total number of participants. Later a network of arbitrary conguration is examined and a tree-based algorithm is proposed. The proposed algorithm requires O(N ) messages and O(logN ) rounds of message...

We argue that the statistical entropy relevant for the thermal interactions of a black hole with its surroundings is (the logarithm of) the number of quantum microstates of the hole which are distinguishable from the hole's exterior, and which correspond to a given hole's macroscopic conguration. We compute this number explicitly from rst principles, for a Schwarzschild black hole, using nonper...

The charter of SRC i s t o a d v ance both the state of knowledge and the state of the art in computer systems. From our establishment in 1984, we h a v e performed basic and applied research to support Digital's business objectives. Our current work includes exploring distributed personal computing on multiple platforms, networking, programming technology, system modelling and management techn...

| This paper studies a family of switchedcurrent and current-mode building blocks for nonlinear sampled-data signal processing and proposes several new switched-current nonlinear circuits which can be designed using the building block approach. The proposed circuits present merits of simple circuit conguration, low voltage and low cost. The development of these circuits has not only expanded th...
