Santbergen, R. (author), Uzu, Hisashi (author), Yamamoto, Kenji (author), Zeman, M. (author)We use simulations to optimize perovskite/silicon tandem solar cells in a novel three-terminal configuration, with one terminal at the front and two at the rear. We consider configurations in which the top cell has either the inverted or the same polarity as the bottom cell. Our goal is to minimize the optical losses, to compare the...journal article 2019

de Athayde Costa e Silva, M. (author), Silvestrini, Stefano (author), Cordeiro Guerrieri, D. (author), Cervone, A. (author), Gill, E.K.A. (author)This brief presents a comprehensive approach for the modeling of micropropulsion systems based on the vaporization of a liquid. The model combines the analytical and empirical relations derived from extensive experimental analysis and fundamental physical laws. This allows modeling of key parameters, such as mass flow rate, for the entire...journal article 2018

Pande, S. (author), Moayeri, M. (author)This paper studies how streamflow predictability varies with basin characteristics. We introduce an index of basin complexity that is based on a model of least statistical complexity that is needed to reliably predict daily streamflow of the basin. We then relate it with climate, vegetation and soil characteristics of the basin. Daily...journal article 2018

Ferrari, Lorenza (author), Yurduseven, O. (author), Llombart, Nuria (author), Yates, Stephen J.C. (author), Bueno, Juan (author), Murugesan, Vignesh (author), Thoen, David (author), Endo, A. (author), Baryshev, AM (author), Baselmans, J.J.A. (author)Next generation sub-mm imaging instruments require kilo-pixel focal plane arrays filled with background limited detectors. Microwave kinetic inductance detectors (MKIDs) are a state-of-the-art detector for future instruments due to their inherent multiplexing capabilities. An MKID consists of a superconducting resonator coupled to a feed-line...journal article 2018

van der El, Kasper (author), Padmos, S. (author), Pool, D.M. (author), van Paassen, M.M. (author), Mulder, Max (author)In manual control tasks, preview of the target trajectory ahead is often limited by poor lighting, objects, or display edges. This paper investigates the effects of limited preview, or preview time, in manual tracking tasks with single- and double-integrator controlled element dynamics. A quasi-linear human controller model is used to predict...journal article 2018

Sharei Amarghan, H. (author), Alderliesten, Tanja (author), van den Dobbelsteen, J.J. (author), Dankelman, J. (author)Guidewires and catheters are used during minimally invasive interventional procedures to traverse in vascular system and access the desired position. Computer models are increasingly being used to predict the behavior of these instruments. This information can be used to choose the right instrument for each case and increase the success rate...review 2018

(author)Cryogenic characterization and modeling of two nanometer bulk CMOS technologies (0.16-μm and 40-nm) are presented in this paper. Several devices from both technologies were extensively characterized at temperatures of 4 K and below. Based on a detailed understanding of the device physics at deep-cryogenic temperatures, a compact...journal article 2018

Roobavannan, M (author), Kandasamy, J (author), Pande, S. (author), Vigneswaran, S (author), Sivapalan, M (author)This study is focused on the water-agriculture-environment nexus as it played out in the Murrumbidgee River Basin, eastern Australia, and how coevolution of society and water management actually transpired. Over 100 years of agricultural development the Murrumbidgee Basin experienced a “pendulum swing” in terms of water allocation, initially...journal article 2017

Santbergen, R. (author), Meguro, Tomomi (author), Suezaki, Takashi (author), Koizumi, Gensuke (author), Yamamoto, Kenji (author), Zeman, M. (author)We present a new version of our optical model for solar cell simulation: GenPro4. Its working principles are briefly explained. The model is suitable for quickly and accurately simulating a wide range of wafer-based and thin-film solar cells. Especially adjusting layer thicknesses to match the currents in multijunction devices can be done...journal article 2017

Yakaboylu, O. (author)In the following decades, biomass will play an important role among the other renewable energy sources globally as it is already the fourth largest energy resource after coal, oil and natural gas. It is possible to obtain gaseous, liquid or solid biofuels from biomass via thermochemical or biochemical conversion routes. Among them, gasification...doctoral thesis 2016

Drop, F.M. (author), Pool, D.M. (author), Mulder, Max (author), Bülthoff, Heinrich H. (author)The human controller (HC) can greatly improve target-tracking performance by utilizing a feedforward operation on the target signal, in addition to a feedback response. System identification methods are used to determine the correct HC model structure: purely feedback or a combined feedforward/feedback model. In this paper, we investigate three...journal article 2016
