Abstract: The paper considers the performance of underwater acoustic ad-hoc networks. A uniform distribution of nodes over a finite area is assumed. The node-to-node channel is modeled through the Ricean fading model. The paper adopts a communication theoretic approach and studies the impact of point-to-point convolutional channel coding on the sustainable number of hops through the network. Numerical examples are presented to illustrate the results of the analysis.

Abstract: Repeated movements of upper extremities cause to overuse injuries however, it is really challenging to determine which of them do so. Primary aim of the project is to determine the effect of different shoulder positions on gripping capability of hand and electro physiologic activity of upper extremity muscles. 23 case report data which have ages ranging between 18 and 30 are analyzed. According to our results, as the shoulder flexion increases, muscular activity and depending on this the muscular exhaustion also increases whereas the functional quality of hand decreases. The case is both a risk factor for an occupational disease and a situation that decreases skillful functioning of hands. For the next researches, advantages of exhaustion reducing apparatus and ergonomic systems, which can be used during works requiring over shoulder movements, are EMG results.
