Performance and event-related potentials (ERPs) were examined in a proactive interference (PI) task with 15 male schizophrenic patients and 15 matched healthy controls. Within a paired-associate task, 30 pairs of semantically unrelated words (A-B) were presented twice, followed by cued recall, in which the paired-associate B had to be named upon cue A. Subsequently, 50% of the A-words were pair...

We present first investigation of Pi 2 pulsations observed from MAGnetic Data Acquisition System (MAGDAS) at Fayum and Aswan stations (FYM and ASW) in Egypt. MAGDAS is an important component of the International Space Weather Initiative (ISWI). We carried out our analysis through a visual inspection comparing our events with burst in AE index during the period from November 2008 to October 2009...

We present a computer vision system for measuring the weight of gobs during a glass-forming process, and a control strategy to automatically correct any weight deviation from a given set point. The system is based on a reliable gob area estimation using image-processing algorithms. A monochrome CCD high-resolution camera and a photodetector for synchronizing acquisition are used for registering...

Geometry measurements are very important to monitor a machine part’s health and performance. Optical measurement system have several advantages for the acquisition of a parts geometry: measurement speed, precision, point density and contactless operation. Measuring parts inside of assembled machines is also desirable to keep maintenance cost low. The Raspberry Pi is a small and cost efficient c...

Introduction: Compressed sensing (CS) is an acquisition and reconstruction technique that can reduce the measurement size [1]. In this work, we present a novel way to efficiently combine CS and parallel imaging (PI) by separating the estimation methods in k-space. We apply CS to estimate high-frequency k-space data, and use ARC (Autocalibrated Reconstruction for Cartesian sampling) PI to estima...

In this paper some upper and lower bounds for the greatest eigenvalues of the PI and vertex PI matrices of a graph G are obtained. Those graphs for which these bounds are best possible are characterized.

We tested the hypothesis that accumulation of H+ or inorganic phosphate (Pi) is responsible for the early contractile failure of hypoxia by measuring maximal Ca2+-activated pressure and 31P nuclear magnetic resonance spectra in Langendorff-perfused ferret hearts at 30 degrees C. Maximal Ca2+-activated pressure was identified by the saturation of pressure with respect to [Ca2+]o observed during ...

This work presents a low-cost robot, controlled by a Raspberry Pi, whose navigation system is based on vision. The strategy used consisted of identifying obstacles via optical flow pattern recognition. Its estimation was done using the Lucas-Kanade algorithm, which can be executed by the Raspberry Pi without harming its performance. Finally, an SVM-based classifier was used to identify patterns...

In this paper a Sliding mode controller (SMC) scheme based on the power rate reaching law approach has been proposed for the inner loop current control of the 3-Phase Brushless DC motor (BLDC) drive. A proportionalintegral (PI) controller is used to control the outer loop speed performance. The developed PI-SMC control scheme is simulated on MATLAB/SIMULINK platform under a sequence of load tor...

The aim of this paper is to implement controllers based on soft computing techniques in real time for a non-linear process. The process taken up for study is to control the level in a conical tank setup using cost effective data acquisition system. The system identification of this nonlinear process is done using black box modeling and found to be First Order Plus Dead Time (FOPDT) model. Then ...
