Zinc oxide (ZnO) is a well-known semiconductor material having very interestingphysical properties that place it among the most promising materials in different fields; such as optics, photovoltaics, electronics, and gas-detection. ZnO is a transparent conducting oxide that has a natural conductivity and a high transparency in the visible.
Providing proper coverage is one of the main applications of wireless sensor networks. In many working environments, it is necessary to take advantage of mobile sensor networks (MSNs), with the capability of having cooperation between sensor nodes and moving into appropriate positions, to provide the required coverage. However, in some applications such as intelligent transport system (ITS), where...
This study examines the postural stability of children with idiopathic scoliosis, using experimental data and a model of sway that includes mediolateral (ML) and anterioposterial (AP) components. The experimental data includes center of pressure (COP) measurements calculated from data acquired using two Advanced Medical Technology, Inc. (AMTI) force plates. Sway metrics are computed and compared with...
This study presents initial results from a bi-planar model used to investigate the neurological factors affecting balance deficits in children with diplegic cerebral palsy (CP). The model uses an inverted pendulum to describe sway in both the anteroposterior (AP) and mediolateral (ML) planes. The study presents Center of Pressure (COP) data from 17 children diagnosed with spastic diplegic CP using...
A multi-root node structure for dynamic multicasting is proposed to support multi-source bidirectional multicasting in IP/MPLS over WDM networks. The blocking probability of this method is studied.
Ankle foot orthoses (AFOs) are prescribed for ambulatory children with spastic diplegia to improve biomechanical alignment and functional capability. The purpose of this study was to employ quantitative motion analysis of the lower extremity to investigate two rehabilitative orthotics. The effects of hinged ankle foot orthoses (HAFO) and dynamic ankle foot orthoses (DAFO) for joint ankle management...
Skeletal deformity is an important characteristic of osteogenesis imperfecta (OI). To study the influence of deformity in stress/strain distribution, a finite element analysis (TEA) of the femur during physiological loading was developed. The diaphysis was altered mathematically to reflect different clinical deformities of OI. Joint reaction and muscle forces were adapted from the literature to reproduce...
This study applies an upper extremity model to analyze motion in 25 children with cerebral palsy using posterior walkers. The study indicates that throughout a gait cycle, the shoulders and wrist are in extension and the elbows are flexed. It also reveals that the elbows are the most asymmetrical joint of the upper extremities during walker-assisted ambulation.
