We introduce a computing mechanism of a biochemical inspiration (similar to a P system in the area of computing by membranes) which consists of a multiset of symbol-objects and a set of nite state sequential transducers. The transducers process symbols in the current multiset in the usual manner. A computation starts in an initial con guration and ends in halting con guration. The power of thes...

The goal of the proposed capacity planning tool is to provide the best cost performance con guration for support of a known media service workload There are two essential components in our capacity planning tool i the capacity measurements of di erent h w and s w solutions using a specially designed set of media benchmarks and ii a media service workload pro ler called MediaProf which ex tracts...

A theory for identi cation and classi cation of two ngered grasps is described and demon strated It is shown that optimal nger positions are obtained from the pairwise intersections of three subsets in the con guration space for the gripper The sets are the symmetry and antisymmetry sets and a third set the critical set of the grasp map Furthermore the three sets themselves form boundaries in a...

This paper presents a variant of probabilistic roadmap methods (PRM) that recently appeared as a promising approach to motion planning. We exploit a free-space structuring of the conŽ guration space into visibility domains in order to produce small roadmaps, called visibility roadmaps. Our algorithm integrates an original termination condition related to the volume of the free space covered by ...

Lack of automatic mapping techniques is a signi cant hurdle in obtaining high performance for general purpose computing on recongurable hardware. In this paper, we develop techniques for mapping loop computations from applications onto high performance pipelined con gurations. Loop statements with generalized directed acyclic graph dependencies are mapped onto multiple pipeline segments. Each p...

To facilitate the writing of large maintainable distributed systems we need to separate out various concerns We view these concerns as being communication computation con guration and coordination We look at the coordination requirements of long running systems pay ing particular attention to enabling the dynamic addition and removal of services We show that the key to a smooth integration of c...

Using density functional theory calculations with van der Waals corrections, we have investigated the stability and electronic properties of monolayer hexagonal boron nitride (hBN) on the Ni(111) surface. We have found that hBN can bind either strongly (chemisorption) or weakly to the substrate with metallic or insulating properties, respectively. While the more stable con ̄guration is the chemi...

We consider the optimum north-south elongation for the Millimeter Array A con guration and interferometric arrays in general. The optimum elongation depends primarily on the observational requirements of the array, with a very weak dependance on the latitude. Assuming that the Millimeter Array A con guration will be used primarily for long integrations, we nd that the optimum north-south axis r...

The environment in which the vehicle must move is often very complex. Furthermore, the vehicle itself may be a complex structure or possess a large degree of exibility. To simplify the detection of collisions, the real-world space is mapped to con guration space. Each dimension in this corresponds to one of the vehicle's degrees of freedom (eg. two spatial and one rotational). In con guration s...

We propose a framework for interaction description based on the paradigm of roles to be used in software development It includes processes to formulate global interaction requirements abstracting from con guration and interaction details and event traces to analyze global interaction properties like deadlock freedom The main constituent of the framework are role descriptions which are structure...
