This paper presents a case study about the applicability and usage of non blocking collective operations. These operations provide the ability to overlap communication with computation and to avoid unnecessary synchronization. We introduce our NBC library, a portable low-overhead implementation of non blocking collectives on top of MPI-1. We demonstrate the easy usage of the NBC library with th...

Domain decomposition methods are widely used to solve in parallel large linear systems of equations arising in the discretization of partial differential equations. Optimized Schwarz Methods (OSM) have been the subject of intense research because they lead to algorithms that converge very quickly. The analysis of OSM has been a very challenging research area and there are currently no general p...

The dynamics of learning from examples in the K = 3 nonoverlapping committee machine with single presentation of examples is studied. The optimal algorithm, in the sense of mean generalization, is obtained from a variational analysis of the diierential equations which describe the dynamics. The agreement of the theoretical predictions and the results of numerical simulations is excellent. The o...

It is possible to employ printed capacitive sensors in car bezel applications because of its lower cost and higher detecting capabilities. In this paper, a flexible sensor for automotive entertainment has been developed using an electrode with interdigitated pattern on it screen printing 3D fabrication processes. Design concerns such as overlap, gap width capacitance changes, production costs w...

The fast Fourier transform (FFT), which is employed by all commercially available ultrasonic systems, provides a time-frequency representation of Doppler ultrasonic signals obtained from blood flow. The FFT assumes that the signal is stationary within the analysis window. However, the presence of short duration embolic signals invalidates this assumption. For optimal detection of embolic signal...

Direct experimental measurement techniques have had limited success in the determination of the two-dimensional (2D) doping profile of a MOSFET. In this paper, we describe an alternative methodology that uses source/drain (S/D) diode and gate overlap capacitance measurements to determine the 2D profile by inverse modeling [l]. Our approach is based on the optimized tensor product spline (TPS) r...

We report the observation of whispering-gallery-mode lasers based on Er(3+) -doped ZBLAN microspheres coupled with half-tapered and tapered optical fibers. A multimode lasing effect is observed at 1.56mu when the taper diameters are properly adjusted so that their fundamental propagation constants match those of the resonant modes of interest. Overlap between the pump and the laser geometrical ...

Abstract As an important class of aggregation operators, the notion overlap functions was first presented in 2009 order to be considered for applications image processing context. Later, many other researches arised bringing some variations those different purposes. Here, our main goal is defining on lattices and discuss how a weakned version it, named quasi-overlaps, works when continuity elim...

In this paper, we propose a novel ICP variant that uses a histogram in conjunction with multiple closest points to detect the overlap area between range images geing registered. Tentative correspondences sharing similar distances are normally all within, or all outside, the overlap area. Thus, the overlap area can be detected in a bin by bin batch manner using a histogram. Using multiple closes...
