Zhu, H. (author), Liu, E. (author), You, Fangzhou (author), de Bont, Cees (author), Gruber, Thorsten (author), Dong, Hua (author), Melles, M. (author)Economic studies have shown that living in poverty may produce a subjective feeling of scarcity, which affects people's cognitive functions and decision-making. Understanding this mechanism could inform healthcare designers on designing inclusive health interventions by considering the psychological scarcity and limited cognitive resources of...book chapter 2024

(author)We report on realization of a 2 × 2 NbN hot electron bolometer (HEB) array receiver using multiple local oscillator (LO) beams that are obtained from a Fourier phase grating mirror. The grating splits a 1.4 THz single beam into four uniform sub-beams. Two 50mm lenses are applied to collimate each beam in order to achieve a spacing of 12mm...conference paper 2015

Influence of different corrosion solutions on reinforced concrete by DIC and traditional strain testWang, XiaoX (author), Liu, JiaP (author), Zhong, PeiH (author)When the corrosion expansion stress of the steel reinforcement exceeds the ultimate tensile strength of the concrete, the concrete will crack and eventually cause structural damage. Therefore, direct characterization methods of steel corrosion expansion stress can help predict the concrete cracking time, prevent corrosion expansion and repair...conference paper 2021

Liu, L. (author), Zlatanova, S. (author)Indoor navigation is gaining an increasing interest among researchers in many domains. In many cases users need to orient quickly in complex environments, which is not always the target of current routing algorithms. The paper reviews current indoor path-finding approaches and discusses some of the limitations. In order to support a natural...conference paper 2011

Liu, Y. (author), Wapenaar, C.P.A. (author), Arntsen, B. (author)The retrieval of the Green's functions between receiver pairs by multi-dimensional deconvolution can be extended to extract the impulse response between source pairs through source-receiver reciprocity. However in general, the procedure requires the separation of the outgoing and incoming wavefields at the sources, which reduces to the...conference paper 2014
