Jing, Guoqing (author), Aela, Peyman (author), Zhou, Qiang (author), Jia, W. (author)The use of recycled materials is a new tendency in the field of railway engineering. Steel slag aggregates (SSA) are one of the recycled materials derived from the steel industry. The application of SSA in ballasted railway tracks requires mechanical examination. In the present paper, the shear behavior of the ballast layer constructed by SSA...conference paper 2022

van Grunsven, J.B. (author)A number of companies have started to developed humanoid robots that (1) bear some physical resemblance to human beings, (2) have some ability to initiate movements (e.g. blinking; head-turning, gyration, etc.) and (3) possess some AI functionalities enabling quasi-intelligent environment-responsiveness and linguistic expression. The robots I am...book chapter 2022

Dào, H.T. (author), Hofland, B. (author), Stive, M.J.F. (author), Mai, Tri (author), Ngo, Anh (author)Wooden fences are nature-based supporting structures to restore mangroves in the Mekong Delta. The hydraulic functioning of wooden fences was studied in previous studies. However, the role of bathymetry in the dissipation and damping of waves by wooden fences has not been studied yet. Thus, in this study, a numerical approach is used to find...conference paper 2022

Yadav, Sunil Kumar (author), Skrodzki, M. (author), Zimmermann, Eric (author), Polthier, Konrad (author)During a surface acquisition process using 3D scanners, noise is inevitable and an important step in geometry processing is to remove these noise components from these surfaces (given as point set or triangulated mesh). The noise removal process (denoising) can be performed by filtering the surface normals first and by adjusting the vertex...book chapter 2022

van de Ruit, M.L. (author), Mugge, W. (author), Schouten, A.C. (author)Careful control of joint impedance, or dynamic joint stiffness, is crucial for successful performance of movement. Time-varying system identification (TV-SysID) enables quantification of joint impedance during movement. Several TV-SysID methods exist, but have never been systematically compared. Here, we simulate time-varying joint behavior...book chapter 2022

(author)Joint impedance plays an important role in postural control and movement. However, current experimental knowledge on lower limb impedance during gait is limited to the ankle joint. We designed the LOwer limb PERturbator (LOPER) aimed to assess knee and hip joint impedance during gait. The LOPER applies force perturbations with a 39 Hz...book chapter 2022

Cavallo, Gaia (author), Cop, Christopher P. (author), Sartori, M. (author), Schouten, A.C. (author), Lataire, John (author)Joint impedance is a common way of representing human joint dynamics. Since ankle joint impedance varies within the gait cycle, time-varying system identification techniques can be used to estimate it. Commonly, time-varying system identification techniques assume repeatably of joint impedance over cyclic motions, without taking into...book chapter 2022

Cop, Christopher P. (author), Schouten, A.C. (author), Koopman, Bart F.J.M. (author), Sartori, M. (author)Quantifying human joint stiffness in vivo during movement remains challenging. Well established stiffness estimation methods include system identification and the notion of quasi-stiffness, with experimental and conceptual limitations, respectively. Joint stiffness computation via biomechanical models is an emerging solution to overcome such...book chapter 2022

Schreier, S. (author), Jacobi, G. (author)For Offshore Floating Photovoltaics (OFPV) applications, thin-film PV panels on lightweight floating support structures gain increasing scientific and commercial interest. Over the past years, several different concepts of thin-film OFPV have been proposed, with the common denominator of floating mattress or blanket-like support structures...conference paper 2022

Ma, L. (author), Kitsak, M.A. (author), Van Mieghem, P.F.A. (author)Despite many studies on the transmission mechanism of the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), it remains still challenging to efficiently reduce mortality. In this work, we apply a two-population Susceptible-Infected-Removed (SIR) model to investigate the COVID-19 spreading when contacts between elderly and non...conference paper 2022

Harrison, J. (author), Alderliesten, T. (author), Bosman, P.A.N. (author)Genetic Programming (GP) can make an important contribution to explainable artificial intelligence because it can create symbolic expressions as machine learning models. Nevertheless, to be explainable, the expressions must not become too large. This may, however, limit their potential to be accurate. The re-use of subexpressions has the...conference paper 2022

Ha, Damy M.F. (author), Deist, Timo M. (author), Bosman, P.A.N. (author)Evolutionary algorithms (EAs) are well-known to be well suited for multi-objective (MO) optimization. However, especially in the case of real-valued variables, classic domination-based approaches are known to lose selection pressure when approaching the Pareto set. Indicator-based approaches, such as optimizing the uncrowded hypervolume (UHV)...conference paper 2022

Yang, C. (author), Zhao, Y. (author), Huang, Lu (author), Xia, Liming (author), Tao, Q. (author)Quantitative MRI (qMRI) of the heart has become an important clinical tool for examining myocardial tissue properties. Because heart is a moving object, it is usually imaged with electrocardiogram and respiratory gating during acquisition, to “freeze” its motion. In reality, gating is more-often-than-not imperfect given the heart rate...conference paper 2022

The attack assumes that the classifier has been made publically available and that the attacker has access to information about a certain number of target individuals. That attacker...conference paper 2022

(TCC 2015) systematically studied the security of Multi-client Verifiable Computation (MVC), in which a set of computationally-weak clients outsource the computation of a general function f over their private inputs to an untrusted server. They introduced the universally composable (UC) security of MVC and proposed a scheme...conference paper 2022
