Toward real-time detection of deep tissue injury risk in wheelchair users using Hertz contact theory

Toward real-time detection of deep tissue injury risk in wheelchair users using Hertz contact theory.

This study assessed the suitability of a new portable system that is based on Hertz's contact theory for evaluating internal gluteal muscle stresses under the ischial tuberosities of wheelchair users in real-time as a risk indicator for a deep tissue injury. Sitting in a wheelchair was monitored and processed with the portable system for six control subjects and five individuals with paraplegia...

Detection of Congenital Mullerian Anomalies Using Real-Time 3D Sonography

Repetitive Strain Injury Among Manual Wheelchair Users

W heelchairs provide mobility for millions of people with physical impairments. However, prolonged manual wheelchair use can lead to pain and repetitive strain injury (RSI) of the upper extremities. The number of manual wheelchair users experiencing pain tends to increase with the time spent using a wheelchair. Although manual wheelchairs have improved tremendously over the past 15 years, many ...

Real-time damage detection of bridges using adaptive time-frequency analysis and ANN

Although traditional signal-based structural health monitoring algorithms have been successfully employed for small structures, their application for large and complex bridges has been challenging due to non-stationary signal characteristics with a high level of noise. In this paper, a promising damage detection algorithm is proposed by incorporation of adaptive signal processing and Artificial...

Real-Time Interference Detection in Tracking Loop of GPS Receiver

Global Positioning System (GPS) spoofing could pose a major threat for GPS navigation ‎systems, so the GPS users have to gain a better understanding of the broader implications of ‎GPS.‎ In this paper, a plenary anti-spoofing approach based on correlation is proposed to distinguish spoofing effects. The suggested ‎method can be easily implemented in tracking loop of GPS receiver...
