Nikaein, T. (author), Kummer, Vineet (author), Steele-Dunne, S.C. (author), Lopez Dekker, F.J. (author)This paper presents an approach to implement a forward model for Sentinel-1 copol and crosspol backscatter and coherence using crop bio-geophysical parameters namely leaf area index, biomass, canopy height, soil moisture and root zone moisture as inputs for the maize. These required input parameters are generated using Decision Support System...conference paper 2022

Li, Shizhen (author), Liu, X. (author), Fan, Jiajie (author), Tan, C. (author), Wang, S. (author), Xie, Bin (author), Ye, H. (author)The wide-bandgap semiconductors represented by GaN have a broad application prospect because of their high service temperature and high switch frequency. Quad-Flat-No-Lead (QFN) Package is currently one of the mainstream packaging methods due to its low cost and high efficiency. However, the low reliability of QFN used in GaN devices is still...conference paper 2022

Hamdar, Samer Hani (author), Talebpour, Alireza (author), D’sa, Kyla (author), Knoop, V.L. (author), Daamen, W. (author), Treiber, Martin (author)Pedestrians are among the travelers most vulnerable to collisions that are associated with high fatality and injury rates. The increasing rate of urbanization and mixed land-use construction make walking (along with other non-motorized travel) a predominant transportation mode with a wide variety of behaviors expected. Because of the inherent...journal article 2022

López, Claudio (author)Electrical power systems are becoming more interconnected and technologically diverse to accommodate ever increasing shares of non-dispatchable generation. These changes are imposing new requirements on the simulation of electrical power systems. One of these requirements is that simulations integrate models of different subsystems, developed by...doctoral thesis 2021

Tian, Cong (author), Wei, Xiaosheng (author)An improved method based on the ring test called eccentric ring test is used to study the cracking of cementitious materials. The water-cement ratios were 0.25, 0.30, 0.35, 0.4 and the aggregate mass fractions were 10%, 30%, 50%, respectively. It was found that with the increase of water-cement ratio and aggregate, the cracking time of the...conference paper 2021

Balog, Krisztian (author), Maxwell, D.M. (author), Thomas, Paul (author), Zhang, Shuo (author)The use of simulation techniques is not foreign to information retrieval. In the past, simulation has been employed, for example, for constructing test collections and for model performance prediction and analysis in a broad array of information access scenarios. Nevertheless, a standardized methodology for performance evaluation via...conference paper 2021

de Jong, Chris P.L. (author), Remes, B.D.W. (author), Hwang, S. (author), de Wagter, C. (author)Increasing endurance is a major challenge for battery-powered aerial vehicles. A method is presented which makes use of an updraft around obstacles to decrease the power consumption of a fixed-wing unmanned aerial vehicle. A soaring flight controller has been developed that can autonomously soar while the unmanned aerial vehicle keeps its...journal article 2021

Andreadis, G. (author), Mastenbroek, Fabian Mastenbroek (author), van Beek, V.S. (author), Iosup, A. (author)Cloud datacenters provide a backbone to our digital society. Inaccurate capacity procurement for cloud datacenters can lead to significant performance degradation, denser targets for failure, and unsustainable energy consumption. Although this activity is core to improving cloud infrastructure, relatively few comprehensive approaches and...journal article 2021

Urbano, Julián (author), Corsi, M. (author), Hanjalic, A. (author)Statistical significance tests are the main tool that IR practitioners use to determine the reliability of their experimental evaluation results. The question of which test behaves best with IR evaluation data has been around for decades, and has seen all kinds of results and recommendations. Definitive answer to this question has recently...conference paper 2021

Khait, M. (author), Voskov, D.V. (author)Alternative to CPU computing architectures, such as GPU, continue to evolve increasing the gap in peak memory bandwidth achievable on a conventional workstation or laptop. Such architectures are attractive for reservoir simulation, which performance is generally bounded by system memory bandwidth. However, to harvest the benefit of a new...conference paper 2021

de Hoon, N.H.L.C. (author)Heart and vessel diseases, or cardiovascular diseases (CVDs), are globally the main cause of mortality and morbidity. The blood flow plays an important role in their occurrence and progression. Therefore, knowledge of the blood flow is of key importance to reduce and threat these diseases. This knowledge requires both high-quality data and an...doctoral thesis 2020

Bal, Frans (author), Vleugel, J (author)In a world where the population and many economies are expanding rapidly the demand for freight transport keeps rising accordingly. As more goods are transported by a growing number of freight vehicles, in particular trucks and sea vessels, their already considerable negative environmental impact also rises. Technology advances, but demand...journal article 2020

van Duin, Ron (author), Enserink, B. (author), Daleman, J.J. (author), Vaandrager, M. (author)The GHG-emissions of the transport sector are still increasing. This trend isaccompanied by the strong growth of the e-commerce sector, leading to moretransport movements on our road networks. In order to mitigate theexternalities of the e-commerce related parcel delivery market and try tomake it more sustainable, the following research question...book chapter 2020

(author), Mulder, Max (author)Objective: We tested whether a procedure in a hexapod simulator can cause incorrect assumptions of the bank angle (i.e., the “leans”) in airline pilots as well as incorrect interpretations of the attitude indicator (AI). Background: The effect of the leans on interpretation errors has previously been demonstrated in nonpilots. In-flight,...journal article 2020

Stroeven, P. (author), Li, Kai (author)Permeability estimates obtained by physical experiments and by simulations differ quite significantly. When biases at the experimental side would be eliminated, the expected modest gap could be bridged by surface layer modifications of the hardened cement paste, discussed herein. This involves the formation of a fractal-like nano-particle...journal article 2020
