Yang, Z. (author), Li, Z. (author)A better understanding of wheel-rail dynamic interaction is necessary for the capacity increase of railway transportation. This chapter briefly introduces the consequences, modeling and detection methods of wheel-rail dynamic interaction, and maintenance of the weak track spots where wheel-rail dynamic interaction often occurs. Wheel-rail...book chapter 2022

van Wee, G.P. (author)Cycling is increasingly receiving attention in research and policy and practice, in many cities and regions in the world. The focus is mainly on cycling infrastructure and effects on travel behavior and health. The economics of cycling have not received a lot of attention yet. This chapter gives an overview of the current state of knowledge...book chapter 2021

Alabart, J. (author), Sanchez-Arcilla, A. (author), Van Vledder, G.P. (author)Wave penetration inside harbours has been one the main issues that port planners and engineers have had to deal with in recent years. Wave conditions inside harbours trigger vessel movements, create dynamic loads on port structures and condition harbour exploitation and safety. For this reason in the recent past maritime and port engineers have...conference paper 2014

Lee, J. (author), Mitici, M.A. (author)Predictive aircraft maintenance is a complex process, which requires the modeling of the stochastic degradation of aircraft systems, as well as the dynamic interactions between the stakeholders involved. In this paper, we show that the stochastically and dynamically colored Petri nets (SDCPNs) are able to formalize the predictive aircraft...conference paper 2021

Kotian, V. (author), Pool, D.M. (author), Happee, R. (author)Users of automated vehicles will move away from being drivers to passengers, preferably engaged in other activities such as reading or using laptops and smartphones, which will strongly increase susceptibility to motion sickness. Similarly, in driving simulators, the presented visual motion with scaled or even without any physical motion causes...conference paper 2023

Wang, N. (author), Verzijlbergh, R.A. (author), Heijnen, P.W. (author), Herder, P.M. (author)This paper reviews the literature on the modeling approaches on decentralized energy investment and operation in the prosumer era. The study has several contributions. Firstly, it adds investment models into the review which have not been previously reviewed for decentralized energy modeling. Secondly, a modeling framework consisting of four...conference paper 2020

(author)With regard to context-aware systems: some optimize system-internal processes, based on the context state at hand; others maximize the user-perceived effectiveness of delivered services, by providing different service variants depending on the situation of the user; still others are about offering value-sensitivity when the society demands so...conference paper 2018

Aydin, B.E. (author), Rutten, M.M. (author), Abraham, E. (author), Oude Essink, GHP (author), Delsman, Joost (author)Surface water salinization in deltaic areas due to saline groundwater exfiltration is an important issue. Saline surface water will not be appropriate for drinking water production, agricultural and industrial use, and therefore, freshwater diverted from rivers is used for flushing the canals and ditches in coastal areas. The effects of climate...conference paper 2017

Wang, L. (author), Qin, Z. (author), Beloqui Larumbe, L. (author), Bauer, P. (author)To accurately simulate the harmonic emission of EV DC fast chargers (DCFCs) and the harmonic voltage of the power grid to which the chargers are connected, a small time-step, i.e., typically smaller than 10μs, is required. However, for harmonic assessment, a long timescale, typically a day, is required. A conflict between accuracy and time...conference paper 2021

Kern, Alexander (author), Mulder, Christoph (author), Hameye, Kay (author), Dong, J. (author)Magnetic force excitations in the air gap of generators can lead to tonal noise emissions of direct-drive wind turbines. Besides the magnetic circuit design, the generator air gap topology has an impact on the excited vibration modes and their frequencies, respectively. For the model-based analysis of the excited force density waves, the spatial...conference paper 2021

Peyghami, S. (author), Blaabjerg, Frede (author), Rueda, José L. (author), Palensky, P. (author)Power electronic converters are one of failure sources in energy systems, and hence drivers of downtime costs in power systems. Different approaches can be employed for converter reliability enhancement including design/control for reliability methods, condition monitoring and fault diagnosis, and maintenance strategies. This paper proposes...conference paper 2020

(author)Floating offshore wind platforms may be subjected to severe sea states, which include both steep and long waves. The hydrodynamic models used in the offshore industry are typically based on potential-flow theory, and/or Morison's equation. These methods are computationally efficient, and can be applied in global dynamic analysis considering...conference paper 2018

Chang, Brian (author), Yang, Liufei (author), Sensi, M. (author), Achterberg, M.A. (author), Wang, F. (author), Rinaldi, M. (author), Van Mieghem, P.F.A. (author)We introduce a Markov Modulated Process (MMP) to describe human mobility. We represent the mobility process as a time-varying graph, where a link specifies a connection between two nodes (humans) at any discrete time step. Each state of the Markov chain encodes a certain modification to the original graph. We show that our MMP model...conference paper 2022

Farajzadeh, R. (author)The results of this thesis give insight into the (mass)-transfer during flow of gases, especially CO2, in various gas-liquid systems. A number of experiments was performed to investigate the transport phenomena through interfaces with and without surfactant monolayers. The observed phenomena have been incorporated into physical models to predict...doctoral thesis 2009

Rahman, R. (author)It has gradually become clear that Peer-to-Peer (P2P) systems should not be conceived in the manner of conventional computing systems. Consequently, over the years, ideas from social science in general and economics in particular have made their way to P2P systems to deal with the novel challenges that such systems throw up. In Chapter 2 of this...doctoral thesis 2011

't Hart, P.A. (author)Device characteristics at cryogenic temperatures can deviate significantly from their room temperature behaviour. For example, the threshold voltage of a MOSFET can increase by more than 100 mV when it is cooled down to 4.2 K, as shown in this thesis. If a designer is not aware of this shift, circuits that work as intended at room temperature...doctoral thesis 2022
