Abstract: Infrastructure safety inspections rely on visual inspections and hammering inspections by inspectors. However, an important difficulty is that inspection results vary because of differences in the technical expertise of inspectors. An inspection method and preventive work using a coating type resin sensor and an infrared camera are proposed to over... Show More

Abstract: We present an assessment tool, based on virtual reality technology, for predicting motor control, attentional or cognitive factors of risk of falls in the elderly. Falls are the leading cause of accidents among the elderly. Each year, it affects 1 in 4 people over the age of 65. In order to better understand and predict this risk of falling, we dev...

Abstract: This paper presents a calibration method for low-cost 3-axis magnetometers using the least square ellipsoid fitting algorithm. The aim of the calibration process is to reduce noise and mitigate the effects of magnetic interferences and instrumentation errors, thereby enhancing the accuracy and reliability of magnetometer measurements. By collecting... Show More
