Characterisation of pavement profile heights using accelerometer readings and a combinatorial optimisation technique

Harris, Niall K. ; González, Arturo ; O'Brien, Eugene J. ; McGetrick, P. (Elsevier, 2010-03)

Pavement surface profiles induce dynamic ride responses in vehicles which can potentially be used to classify road surface roughness. A novel method is proposed for the characterisation of pavement roughness through an ...
A method for monitoring reactive strength index

Patterson, Matthew ; Caulfield, Brian (Elsevier, 2010-06)

Ubiquitous motion sensors in shoes and clothing are becoming more prevalent. This new data stream opens a large opportunity to gain a deeper understanding of human movement. This paper describes the development and validation ...
Two Stage Kalman Filtering for Position Estimation Using Dual Inertial Measurement Units

Yadav, Nagesh ; Bleakley, Chris (IEEE, 2011-10-28)

Herein a two stage Kalman filter based algorithm is proposed for processing of Inertial Measurement Unit (IMU) data to obtain accurate position estimation over a short period of time. The proposed algorithm uses a novel ...
The use of vehicle acceleration measurements to estimate road roughness

González, Arturo ; O'Brien, Eugene J. ; Li, Yingyan ; Cashell, K. (2008-06)

Road roughness is a broad term that incorporates everything from potholes and cracks to the random deviations that exist in a profile. To build a roughness index, road irregularities need to be measured first. Existing ...
