In ambient monitoring applications, the sensing field may be so far away from the data center that causes the direct relay routes between the sensor network and the data center impossible. Typically, in such isolated sensor network, data is stored in a distributed manner and collected by data mule. To improve the efficiency, sensed data is normally stored near the area where the mule will pass ...

UNLABELLED The list of individualized needs of the wheelchair user as developed by the medical and personal profile assessment can be categorized under the general goals to be accomplished through the process of the wheelchair recommendation: MEDICAL PROFILE: MEDICAL HISTORY (1) Compensate for loss or absence of function. (2) Promote good health through prevention of problems. Physical Assess...

BACKGROUND This study examines the relationship between race and mobility over 5 years in initially well-functioning older adults and evaluates how a broad set of socioeconomic status indicators affect this relationship. METHODS Data were from 2,969 black and white participants aged 70-79 from the Health, Aging, and Body Composition study. Mobility parameters included self-reported capacity t...

OBJECTIVE Compare the quality of life (QOL) of youth living with visible facial differences (FDs) with youth living with a visible nonfacial difference (i.e., mobility limitations), an invisible difference (i.e., attention deficit/hyperactivity disorder), or no known difference. DESIGN An observational study of perceived QOL among adolescents with FDs (n = 56), adolescents with no diagnosed c...

nowadays the position of the renewable energy is so important because of the environment pollution and the limitation of fossil fuels in the world. energy can be generated more and more by the renewable sources, but the fossil fuels are non-renewable. one of the most important renewable sources is the wind energy. the wind energy is an appropriate alternative source of fossil fuel. the replacem...

a wireless sensor network consists of many inexpensive sensor nodes that can be used toconfidently extract data from the environment .nodes are organized into clusters and in each cluster all non-cluster nodes transmit their data only to the cluster-head .the cluster-head transmits all received data to the base station .because of energy limitation in sensor nodes and energy reduction in each d...

objectives: although for those spinal cord injury (sci) patients with paralysis of the legs but not at arms, the primary means of mobility post injury is the manual wheelchair, there are many physiological and psychological advantages to standing and walking, such as improvement in respiratory function, lower limb weight bearing and preventing osteoporosis, pressure sores prevention etc. high m...
