Object Classification on a Conveying Belt

This paper describes a system for object detection on a conveying belt. The detection algorithms are based on the permanence effect that basically consists on increasing a state variable associated to each pixel of the sensor when the moving element is located on that particular pixel point, and to decrease it otherwise. Using this permanence effect, a characteristic called LSR can be obtained ...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

On the Electrostatics of Pneumatic Conveying of Granular Materials

In this work the electrostatics of the pneumatic conveying of granular materials in a non-conducting (PVC) vertical pipe is studied using Electrical Capacitance Tomography (ECT) system. The non-conducting wall in general attains static charges arising from particle-wall collisions in the initial periods of conveying process and then reaches equilibrium with the surroundings. The polarity of par...
