Bearings-only aerial shooter localization using a microphone array mounted on a drone
(Journal article, 2017)Estimating the direction of arrival (DoA) of an audio signal from an aerial platform gives way to estimating the localization of the source. This paper addresses the problem of airborne shooter localization using an array ... -
Belief Propagation Detection For Large-Scale MIMO Systems With Low-Resolution ADCs
(Peer reviewed; Journal article, 2019)We derive the belief propagation (BP) detector for large-scale multiple-input multiple-out communication systems where the low-resolution analog-to-digital converters (ADCs) are used to save the power and hardware costs. ... -
Beyond CMOS: Ternary and mixed radix CNTFET circuit design, simulation and verification
(Journal article; Peer reviewed, 2022)For three-valued or ternary computing to be an alternative for binary, new multiple valued logic (MVL) electronic design automation (EDA) tools are needed. In this article we present a novel MVL logic synthesis tool to ... -
Bridging the Gap Between Bio-inspired Steering and Locomotion: a Braitenberg Snake Robot
(Chapter, 2018)Braitenberg vehicles are simple models of animal motion towards, or away from, a stimulus (light, sound, chemicals, etc). They have been widely used in robotics to implement target reaching and avoidance behaviors based ... -
Cause and Impact Analysis of Cost and Schedule Overruns in Subsea Oil and Gas Projects – A Supplier’s Perspective
(Journal article; Peer reviewed, 2017)Abstract. This paper identifies drivers for cost and schedule overruns in subsea production system projects from a supplier’s point of view. Subsea Production Systems connects subsea wells to offshore vessels, and enable ... -
