Software distributed shared memory (DSM) improves the programmability of message-passing machines and workstation clusters by providing a shared memory abstract (i.e., a coherent global address space) to programmers. As in any distributed system, however, the probability of software DSM failures increases as the system size grows. This paper presents a new, efficient logging protocol for adapti...

Spiculated margins indicate a high risk of malignancy for breast cancer. Detection accuracy of current computerized diagnostic systems Computer Aided Detections (CADs) for spiculated margins is not high due to the existence of intensity heterogeneities, often subtle and varied in appearance. This paper presents an automatic system for Accurately Detection of Spiculated Margins (ADSM) by measuri...

Ventilatory equivalents for oxygen and carbon dioxide are physiological measures of breathing efficiency, and are known to be affected by the intensity and mode of exercise. We examined the effect of level running (gradient 0%) and muscle-damaging downhill running (−12%), matched for oxygen uptake, on the ventilatory equivalents for oxygen (V̇E/V̇Ο2) and carbon dioxide (V̇E/V̇CO2). Nine men (27 ± 9...

Although the brain is not perfectly symmetrical with respect to the mid-sagittal plane, the automatic detection of this plane and of the degree of symmetry is of interest for many anatomical and functional studies. We propose a method for detecting the best symmetry plane in 3D MR brain images. We express this problem as a registration problem and compute a degree of similarity between the imag...

The paper deals with testing and evaluation of selected modified heuristic optimization methods Random Search, Downhill Simplex, Hill Climbing, Tabu Search, Local Search, Simulated Annealing, Evolution Strategy; Differential Evolution and Self Organizing Migrating Algorithm. The optimization methods were tested on four standard testing functions – the domain of the function is a defined step fo...

In deep learning-based local stereo matching methods, larger image patches usually bring better accuracy. However, it is unrealistic to increase the size of patch without restriction. Arbitrarily extending will change method into global method, and accuracy be saturated. We simplified existing Siamese convolutional network by reducing number parameters propose an efficient CNN based structure, ...

This paper introduces and analyzes the algorithm of Parallel Genetic Alogrithm (PGA) embedded with Downhill which is applied to the optimization of continuous functions. The strategy goes this way: Subpopulation tries to locate good local minima by PGA. When a subpopulation does not progress after a certain number of generations, downhill is taken into account. Alternative downhill method (dept...

We study the parallelization of the steepest-edge version of the dual simplex algorithm. Three different parallel implementations are examined, each of which is derived from the CPLEX dual simplex implementation. One alternative uses PVM, one general-purpose System V shared-memory constructs, and one the PowerC extension of C on a Silicon Graphics multi-processor. These versions were tested on ...

For the safety problem of heavy duty vehicles running on long downhill sections, a model was built for the application of engine brake and service brake combination based on test results. And a model of brake temperature rise for heavy duty vehicles running on long downhill sections was also established. For different braking modes, gear positions, speed and downhill slopes, brake temperature r...
