Cooperative Relay Selection For Load Balancing With Mobility In Hierarchical Wsns: A Multi-Armed Bandit Approach, Jian Zhang, Jian Tang, Feng Wang
Faculty and Student Publications
© 2013 IEEE. Energy efficiency is the major concern in hierarchical wireless sensor networks(WSNs), where the major energy consumption originates from radios for communication. Due to notable energy expenditure of long-range transmission for cluster members and data aggregation for Cluster Head (CH), saving and balancing energy consumption is a tricky challenge in WSNs. In this paper, we design a CH selection mechanism with a mobile sink (MS) while proposing relay selection algorithms with multi-user multi-armed bandit (UM-MAB) to solve the problem of energy efficiency. According to the definition of node density and residual energy, we propose a conception referred to …

The natural environment poses a significant number of obstacles and dynamic settings that makes mobility difficult for those with physical and mobility impairments. To approach this problem, a suspension was designed using inspiration from the early Mars rovers developed by NASA for traversing the varied Martian landscape. The course of the project followed the direction of a start-up through problem identification, early design generation and review, and final design production. The project outcome, through client request and proven market research, aimed to produce a multi-terrain wheelchair. The final product is a kinematic body with mobile front “legs” and a rotational …

Currently, there is limited research of the biomechanics of pediatric manual wheelchair mobility. Specifically, the biomechanics of functional tasks and their relationship to joint pain and health is not well understood. To contribute to this knowledge gap, a quantitative rehabilitation approach was applied for characterizing upper extremity biomechanics of manual wheelchair mobility in children and adolescents during propulsion, starting, and stopping tasks. A Vicon motion analysis system captured movement, while a SmartWheel simultaneously collected three-dimensional forces and moments occurring at the handrim. A custom pediatric inverse dynamics model was used to evaluate three-dimensional upper extremity joint motions, forces, and moments …
Design And Validation Of A Full Contact Gait Simulator For The Cadaveric Lower Extremity, Joseph Michael Iaquinto
Design And Validation Of A Full Contact Gait Simulator For The Cadaveric Lower Extremity, Joseph Michael Iaquinto
Theses and Dissertations
The projects goal was to create a device to simulate full contact gait in the cadaveric lower extremity. The Contact Gait Simulation System loads specific muscles to recreate anatomical dorsi and plantar flexion of the ankle under axial loading. A system of pneumatic load generation was connected a LabVIEW virtual instrument (VI), which controlled the application of these loads. The loads were roughly based off literature cited EMG data, and further modified from feedback. In addition to controlling the load system, the VI also coordinates external sensor timing. Along with this simulator, software was developed specifically for analyzing pressure data …
