Weerheijm, J. (author), Lu, Y. (author), Xu, J. (author)This paper presents a numerical modelling study on the simulation of the cracking process and fracture energy in concrete under high strain rate. To capture the stress wave effect and the damage evolution at the meso-length scale, both a homogeneous model with a millimetreresolution mesh and an explicit heterogeneous mesoscale model with random...conference paper 2013

Xu, J. (author), Yazicioglu, Refet Firat (author), Grundlehner, Bernard (author), Harpe, Pieter (author), Makinwa, K.A.A. (author), Van Hoof, Chris (author)This paper presents an active electrode system for gel-free biopotential EEG signal acquisition. The system consists of front-end chopper amplifiers and a back-end common-mode feedback (CMFB) circuit. The front-end AC-coupled chopper amplifier employs input impedance boosting and digitally-assisted<br/>offset trimming. The former increases the...journal article 2011
