Natural language processing tools are used to automatically detect disturbances in transcribed speech of schizophrenia inpatients who speak Hebrew. We measure topic mutation over time and show that controls maintain more cohesive speech than inpatien

This paper presents a method for the solution of parabolic PDEs on parallel computers, which is a combination of implicit and explicit finite difference schemes based on a domain decomposition (DD) strategy. Moreover, this method is asynchronous (i.e

In achieving significant speed-up on parallel machines, a major obstacle is the overhead associated with synchronizing the concurrent processes. This paper presents high-orderparallel asynchronous schemes, which are schemes that are specifically desi

Parallel elliptic single/multigrid solutions around an aligned and nonaligned body are presented and implemented on two multi-user and single-user shared memory multiprocessors (Sequent Symmetry and MOS) and on a distributed memory multiprocessor (a

General high-resolution smoothing techniques for estimating deterministic sinusoidal frequencies from short-record noisy data are presented. Symmetric smoothings are proven to provide conjugate reciprocal polynomial roots also in the noisy case and t

New asynchronous and time stabilizing finite-difference methods for constant coefficient parabolic PDEs are presented. These schemes remove the synchronization overhead and are suitable for shared-memory, message-passing, single- or multi-user multi-

In this paper we consider an object detection problem for image based surveillance system that works in a predefined area. A real environment is a random spatial and temporal changing background, e.g. water waves, light, wind, rain, fog, etc. The sus

The performance of the Viterbi and the interacting multiple model (IMM) algorithms, applied to radar tracking and detection, are investigated and compared. Two different cases are considered. In the first case, target acceleration is identical to one
