Background: Generalized joint hyper mobility predisposes some individuals to a wide variety of musculoskeletal complaints. Given the critical role of scapular position in function of shoulder, the aim of this study was to compare scapular position between persons with and without general joint hyper mobility. Methods: By nonprobability sampling 30 hyper mobile persons at average of 22.86 ±2.77...

Based on application requirements, nodes are static or mobile in Wireless Sensor Networks (WSNs). Mobility poses challenges in protocol design, especially at the link layer requiring mobility adaptation algorithms to localize mobile nodes and predict link quality to be established with them. This study implements XMAC and Berkeley Media Access Control (BMAC) routing protocols to evaluate perfor...

fractional flow analysis confirms the advantages of surfactant alternative gas injection (sag) in enhanced oil recovery, but an adsorption phenomenon that has been affected by several factors, weakens the effectiveness of sag injection. in this study, the effects of sacrificial agent, gas phase, and surfactant concentration on adsorption density on silica mineral were investigated by static and...

In this paper, we propose several novel fast converging mobility control protocols to achieve optimal deployment for streaming data flows in wireless sensor networks (WSNs). We also identify a unique sink privacy issue in mobility control protocols and propose a new privacy-preserving scheme which can be integrated into mobility control protocols to protect the sink. The simulation and performa...

In this pilot study we investigated the ability of five infants from 6 to 9 months of age to learn to drive the WeeBot, a mobile robot controlled by weight shift over a Wii balance board, over five training sessions. Infants demonstrated continued improvement in driving performance in a training protocol and in time-in-motion and goal-directed behavior during the free play sessions. The Wii pro...
