Numerical Relativity (NR) uses advanced numerical techniques in supercomputers to simulate the relativistic, strong-field dynam s and radiation of merging compact binaries, such as black holes and neutron tars, and oth r s milar phenomena that are governed by E nstein's th ory of General R lativi y (GR). Analytical relativity (AR) metho s, based on Po -Newtonian exp ns ons of the GR qua ion nd ...

-Certain classes of elementary operations on the system matrix of a linear system are defined, and then their use IS illustrated for the calculation of canonical forms, the largest (A,B)-mvarmnt and controllablhty subspaces in ker(C), transmission zeros, and minimal inverses Questions of numerical accuracy are discussed The results are directly codable as efficient numerical algorithms, and may...

PRELIMINARY CONSIDERATIONS The spreading depression of Lefio has been well estabhshed as a reproducible reaction m the hssencephahc rabbat (Lefio 1944a b 1947 1945) The reaction can be initiated by weak mechamcal or electrical stamulat~on apphed to the surface of the pm-arachno~d membranes or ~t can also be mttmted by mtense neuronal activity It conststs of a slowly expanding wave of depression...

The objective of this study was to obtain a quantitative understanding of the crateting process over a broad range of conditions. Our approach was to numerically compute the evolution of impact induced flow fields and calculate the time histories of the key measures of crater geometry (e.g. depth, diameter, lip height) for 9 2 variations in planetary gravity (0 to 10 cin/s ), material strength ...

Interventions to support individuals with cognitive disabilities surrounding the organization of time and activities often include what are known as visual schedules. These artifacts use words, images, and sometimes tangible objects to represent activities that will take place (or have taken place) arranged in temporal order to augment understanding of time, events, and places. Use of visual sc...

Clique is a HP Labs Grenoble project. The goal is to develop a novel peer-to-peer, server-less distributed file system based on optimistic replication algorithms, which transparently integrates into users’ native file systems. Some properties of the Clique system are epidemic replication, a no lost updates consistency model and conflict management, as well as disconnected operation and replica ...

For almost a century, various predictions have been made that the human race was imminently going to run out of available petroleum. The passing of time has proven all those predictions to have been utterly wrong. It is pointed out here how all such predictions have depended fundamentally upon an archaic hypothesis from the 18th century that petroleum somehow (miraculously) evolved from biologi...
