The RDT network router chip
The RDT network Router chip is a versatile router for the massively parallel computer prototype JUMP-1, which is currently under development by collaboration between 7 Japanese universities[1]. The major goal of this project is to establish techniques for building an e cient distributed shared memory on a massively parallel processor. For this purpose, the reduced hierarchical bit-map directory...
متن کاملNonlinear RDT theory of near-wall turbulence
A WKB method was recently used to extend rapid distortion theory (RDT) to initially inhomogeneous turbulence strained by irrotational mean flows [S.V. Nazarenko, N. Kevlahan, B. Dubrulle, J. Fluid Mech. 390 (1999) 325]. This theory takes into account the feedback of turbulence on the mean flow, and it was used by Nazarenko et al. to explain the effect of strain reduction caused by turbulence ob...
متن کاملEffect of mechanically simulated diaphragmatic respiratory motion on myocardial SPECT processed with and without attenuation correction.
UNLABELLED The goal of this study was to assess the effect of diaphragmatic respiratory motion on inferior wall cold artifact in myocardial SPECT and to assess the ability of attenuation correction (AC) to correct for this artifact in the presence of diaphragmatic motion. METHODS We used an anthropomorphic phantom with ventricular wall activity, variable ventricular caudal tilt, attenuating l...
متن کاملReaction Decoder Tool (RDT): extracting features from chemical reactions
UNLABELLED Extracting chemical features like Atom-Atom Mapping (AAM), Bond Changes (BCs) and Reaction Centres from biochemical reactions helps us understand the chemical composition of enzymatic reactions. Reaction Decoder is a robust command line tool, which performs this task with high accuracy. It supports standard chemical input/output exchange formats i.e. RXN/SMILES, computes AAM, highlig...
متن کاملRDT+: A parameter-free algorithm for exact motion planning
In this paper parameter-free concepts for exact motion planning are investigated. With the proposed RDT approach the collision detection parameters of a Rapidlyexploring Dense Tree (RDT) are automatically adjusted until an exact solution can be found. For efficient planning discrete collision detection routines are used within the RDT planner and by verifying the results with exact collision de...
