In this paper, the effect of yttrium oxide nanoparticles on the optical properties of polymethylmethacrylate has been investigated. The results show that the optical constants of (PMMA-Y2O3) nanocomposites are increasing with the increase of the yttrium oxide nanoparticles concentrations. The energy band gap of (PMMA-Y2O3) nanocomposites decreases with the increase of the yttrium oxide nanoparticles concentrations.

Vision based human action recognition allows to detect and understand meaningful human motion. In this method, human silhouette extraction technique like background subtraction is applied. The extracted human silhouettes are processed in order to obtain the contour based feature. Finding the most characteristic poses among the training data returns the key poses. K-means clustering is an efficient technique to cluster poses based on attributes like distance. With reference to Weizmann dataset, six actions such as running, walking, jumping, bending, waving one hand and waving two hands are considered. The actions are learned by making use of sequences of key poses. The sequence of key poses model the temporal evolution between key poses with respect to the original training sequences. Action recognition is done by means of Minimum Distance Classifier. Action recognition of unknown key poses is matched with known classes of cluster center, then the correct action is recognized. Weizmann dataset deals with single view scenarios with an average success rate of 93%.

Discharges of domestic and industrial wastewater in the two banks of the Bouregreg River without any treatment, usually has a large number of health and environmental risks, among these water pollution by dangerous chemicals. The Objective of this study is to follow the variation of the conductivity of wastewater discharged into the Bouregreg river depending on the anions concentration of chlorides (Cl-), sulfates (SO42-), bicarbonates (HCO3-) and nitrates ( NO3-) to determine the ions that have an effect on this physicochemical parameter for modeling and optimization this parameter according anions analyzed in wastewater discharged into the Bouregreg river with help of the experimental designs method and isoresponses curves.
