16.8 Monolithic all-perovskite triple-junction solar cells via a universal two-step solution processWang, J. (author), Zardetto, V. (author), Datta, K. (author), Zhang, D. (author), Wienk, M.M. (author), Janssen, R.A.J. (author)Perovskite semiconductors hold a unique promise in developing multijunction solar cells with high-efficiency and low-cost. Besides design constraints to reduce optical and electrical losses, integrating several very different perovskite absorber layers in a multijunction cell imposes a great processing challenge. Here, we report a versatile two...article 2020

Aliman, N.M. (author), Kester, L.H.J.M. (author)In recent years, prevalent global societal issues related to fake news, fakery, misinformation, and disinformation were brought to the fore, leading to the construction of descriptive labels such as “post-truth” to refer to the supposedly new emerging era. Thereby, the (mis-)use of technologies such as AI and VR has been argued to potentially...article 2020

(author)An increasing number of schools obtained a Healthy School certificate, yet little is known about factors, characteristics, and processes, i.e. conditions, influencing the effectiveness of the Healthy School program. Therefore, a mixed methods evaluation study will be conducted on three levels: the student, the school, and the region. The...article 2020

(author)Automatic detection and tracking of persons and vehicles can greatly increase situational awareness in many military applications. Various methods for detection and tracking have been proposed so far, both for rule-based and learning approaches. With the advent of deep learning, learning approaches generally outperform rule-based approaches. Pre...conference paper 2020

(author), Markopoulus, P. (author)Design cards are a popular way for designers to encode and communicate design knowledge. Aiming to inform the designers of such design tools we set out to characterize the design space of design cards in a two-pronged approach involving a) a systematic literature survey on the use of design cards and b) card sorting interviews, which were...conference paper 2020

Toet, A. (author), Hoogervorst, M.A. (author)In military operations signature reduction techniques such as camouflage nets, low-emissive paints, and camouflage patterns are typically deployed to optimize the survivability of high value assets by minimizing their detectability. Various methods have been developed to assess the effectiveness of these camouflage measures. There are three main...article 2020

(author)(m, k)-firm real-time tasks require meeting the deadline of at least m jobs out of any k consecutive jobs. When compared to hard real-time tasks, (m, k)-firm tasks open up the possibility of tighter resource-dimensioning in implementations. Firmness analysis verifies the satisfaction of (m, k)-firmness conditions. Scheduling policies under which...conference paper 2020

de Boer, M.H.T. (author), Verhoosel, J.P.C. (author)Creating ontologies is an expensive task. Our vision is that we can automatically generate ontologies based on a set of relevant documents to create a kick-start in ontology creating sessions. In this paper, we focus on enhancing two often used methods, OpenIE and cooccurrences. We evaluate the methods on two document sets, one about pizza and...conference paper 2020

Hur, C. (author), Berdowski, T. (author), Ferreira, C. (author), Schepers, G. (author), Boorsma, K. (author)BEM (Bladed Element Momentum) models have shown to be inaccurate in predicting loads in the case of yawed flow [1-3]. Actuator disk momentum theory is the basis for BEM codes, following Glauert's auto-gyro theory [4]. Therefore, a first step to improve BEM in yawed flow is to assess momentum models for the actuator disk in yaw and investigate...conference paper 2019
