Belfiori, F. (author), van Rossum, W.L. (author), Hoogeboom, P. (author)This paper investigates the use of a 2D MUSIC algorithm for the joint estimation of angular and range target locations. Coherency and correlation characteristics of the target signals are taken into account and 2D spatial smoothing technique is preliminarily applied in order to ensure the non-singularity of the received signals covariance matrix...conference paper 2012

(author)Nano-satellites have a cost advantage due to their low mass and usage of commercial-off-the-shelf technologies. However, the low mass also restricts the functionality of a nano-satellite's payload. Typically, this would imply instruments with very low to low resolution and accuracy, essentially ruling out applications such as remote sensing....conference paper 2012

(author)Dual-gate organic transistor technology is used to increase the robustness of digital circuits as illustrated by higher inverter gains and noise margins. The additional gate in the technology functions as a VT-control gate. Both zero-VGS-load and diode-load logic are investigated. The noise margin of zero- VGS-load inverter increases from 1.15 V...article 2011

Myny, K. (author), van Veenendaal, E. (author), Gelinck, G.H. (author), Genoe, J. (author), Dehaene, W. (author), Heremans, P. (author)We introduce a microprocessor made by organic thin-film transistors processed directly onto flexible plastic foil. This is a direct realization of a microprocessor by thin-film technology, i.e., without transfer, on plastic. It paves the way to equip mundane supports and objects with low-cost computing power. We also demonstrate the correct...conference paper 2011

Toet, A. (author)The predictions of 13 computational bottom-up saliency models and a newly introduced Multiscale Contrast Conspicuity (MCC) metric are compared with human visual conspicuity measurements. The agreement between human visual conspicuity estimates and model saliency predictions is quantified through their rank order correlation. The maximum of the...article 2011

(author)Digital subscriber line (DSL) data rates for short loops are typically limited by crosstalk between adjacent lines rather than by background noise. Precoding can reduce crosstalk in the downstream from the access node to the customer premises equipment significantly if an accurate estimate of the inverse crosstalk channel is provided. Recently,...article 2011
