Klok, Lana (author)Frail elderly have an increased risk to get involved with care. Shared decision making can help ensure that this care contributes to the elderly´s quality of life, instead of only extending life. To enable shared decision making, clear communication between the elderly and care professionals is needed, however, this communication is especially...master thesis 2019

Sheldon, R.A. (author)Two of the grand societal and technological challenges of the twenty first century are the 'greening' of chemicals manufacture and the ongoing transition to a bio-based economy: that is a sustainable, carbon-neutral economy based on renewable biomass as the raw material. These challenges are motivated by the need to eliminate environmental...journal article 2019

Bae, D. (author), Seger, Brian (author), Hansen, Ole (author), Vesborg, Peter C.K. (author), Chorkendorff, Ib (author)This work investigates long-term photoelectrochemical hydrogen evolution (82 days) in 1 M HClO4 using a TiO2:H protected crystalline Si-based photocathode with metal-oxide-semiconductor (MOS) junctions. It is shown that day/night cycling leads to relatively rapid performance degradation while the photocurrent under the continuous light condition...journal article 2019

Xie, S. (author), Theuwissen, A.J.P.A.M. (author)This paper analyzes and compensates for process and temperature dependency among a (Complementary Metal Oxide Semiconductor) CMOS image sensor (CIS) array. Both the analysis and compensation are supported with experimental results on the CIS’s dark current, dark signal non-uniformity (DSNU), and conversion gain (CG). To model and to...journal article 2019

Zhang, Chunyan (author), Liu, Bin (author), Yu, Baoxing (author), Lu, Xiaopeng (author), Wei, Yong (author), Zhang, Tao (author), Mol, J.M.C. (author), Wang, Fuhui (author)Surface pretreatment is generally applied before application of protective coatings on Mg alloys, which influences surface microstructure and electrochemical activity of the substrate and has an effect on the coating properties. The effect of various pretreatment processes (sand-blasting, grinding and polishing) on the microstructure and...journal article 2019

Merkx, E.P.J. (author), van Overbeek, S. (author), van der Kolk, E. (author)SiAlON window coatings are applied on an industrial scale to achieve e.g. scratch-resistance and anti-reflection. Doping these SiAlONs with rare-earths adds luminescent functionality, which could be applied in photovoltaics. By using a combinatorial reactive sputtering approach, an amorphous thin film composition library with a Si:Al ratio...journal article 2019

(author), Demiris, Yiannis (author), Kiefer, Bernd (author), Fumagalli, Diego (author), Bierman, Bert (author)Social or humanoid robots do hardly show up in “the wild,” aiming at pervasive and enduring human benefits such as child health. This paper presents a socio-cognitive engineering (SCE) methodology that guides the ongoing research & development for an evolving, longer-lasting human-robot partnership in practice. The SCE methodology has been...journal article 2019

Raman, C.A. (author), Hung, H.S. (author)The detection of free-standing conversing groups has received significant attention in recent years. In the absence of a formal definition, most studies operationalize the notion of a conversation group either through a spatial or a temporal lens. Spatially, the most commonly used representation is the F-formation, defined by social...conference paper 2019

Rosatelli, A. (author), Gedik, E. (author), Hung, H.S. (author)In this paper, we investigate the use of proxemics and dynamics for automatically identifying conversing groups, or so-called F-formations. More formally we aim to automatically identify whether wearable sensor data coming from 2 people is indicative of F-formation membership. We also explore the problem of jointly detecting membership and...conference paper 2019

A Supply Pushing Reduction Technique for LC Oscillators Based on Ripple Replication and CancellationChen, Y. (author), Liu, Yao-Hong (author), Zong, Z. (author), Dijkhuis, Johan (author), Dolmans, Guido (author), Staszewski, R.B. (author), Babaie, M. (author)In this paper, we propose a method to suppress supply pushing of an LC oscillator such that it may directly operate from a switched-mode dc-dc converter generating fairly large ripples. A ripple replication block (RRB) generates an amplified ripple replica at the gate terminal of the tail current source to stabilize the oscillator's tail...journal article 2019

Sheldon, R.A. (author)Biocatalysis has emerged in the last decade as a pre-eminent technology for enabling the envisaged transition to a more sustainable bio-based economy. For industrial viability it is essential that enzymes can be readily recovered and recycled by immobilization as solid, recyclable catalysts. One method to achieve this is via carrier-free...journal article 2019

Tielman, M.L. (author), Neerincx, M.A. (author), Pagliari, Claudia (author), Rizzo, Albert (author), Brinkman, W.P. (author)Background: Digital health interventions can fill gaps in mental healthcare provision. However, autonomous e-mental health (AEMH) systems also present challenges for effective risk management. To balance autonomy and safety, AEMH systems need to detect risk situations and act on these appropriately. One option is sending automatic alerts to...journal article 2019
