Peng, Q. (author), Vermolen, F.J. (author), Weihs, D. (author)Cancer cell migration between different body parts is the driving force behind cancer metastasis, which causes mortality of patients. Migration of cancer cells often proceeds by penetration through narrow cavities in possibly stiff tissues. In our previous work [12], a model for the evolution of cell geometry is developed, and in the current...book chapter 2023

Groves, R.M. (author), Ameng, L. (author), Xiaoli, L. (author), Hackney, S. (author), Peng, X. (author), Osten, W. (author)Advanced measurement techniques for the structural diagnostics of artwork are increasingly providing more complex data that needs to be conveyed to conservators in a meaningful way. Holography and speckle interferometry based sensors are commonly used for this application and of these shearography is quite suitable for measurements outside the...conference paper 2009

Peng, D.L. (author), Meijers, B.M. (author), van Oosterom, P.J.M. (author)When users zoom out on a digital map, some area objects become too tiny to be seen, resulting in visual clutters. To avoid this problem, the relatively unimportant areas should be merged with their neighbors to form larger<br/>areas. In order to provide small and smooth changes so that users can easily keep their contexts, we merge a pair of...conference paper 2020

Peng, D.L. (author), Meijers, B.M. (author), van Oosterom, P.J.M. (author)This paper presents a web map juxtaposition comparer. Using the comparer, we can place two maps side by side for comparison. The maps of the comparer can contain multiple layers, and each of them can be a multi-scale layer<br/>or a vario-scale layer. We enhance the comparer’s visual analytical ability by developing more functionalities,...conference paper 2020

Peng, Yixuan (author), Bruyns, Gerhardes (author), Qu, L. (author)In the past century, cities have undergone revolutionary changes from planning paradigms to urban forms. As the fastest urbanizing country in the world, China’s urbanization process has also been accompanied by dramatic changes in urban planning models and has emerged substantial real estate driven compounds in the form of megablock. In December...conference paper 2021

Tsouvalas, A. (author), Peng, Y. (author), Metrikine, A. (author)In this paper, a pile-water-soil model is developed for the prediction of sound generated due to impact piling. The complete model consists of two modules: i) a near-source module aiming at the accurate description of the pile-water-soil interaction together with the sound generation and propagation in the vicinity of the pile; and ii) a far...conference paper 2019

Iqbal, Shariq (author), Witt, Christian A. Schroeder de (author), Peng, Bei (author), Böhmer, J.W. (author), Whiteson, Shimon (author), Sha, Fei (author)Real world multi-agent tasks often involve varying types and quantities of agents and non-agent entities; however, agents within these tasks rarely need to consider all others at all times in order to act effectively. Factored value function approaches have historically leveraged such independences to improve learning efficiency, but these...conference paper 2021

Gupta, Tarun (author), Mahajan, Anuj (author), Peng, Bei (author), Böhmer, J.W. (author), Whiteson, Shimon (author)VDN and QMIX are two popular value-based algorithms for cooperative MARL that learn a centralized action value function as a monotonic mixing of per-agent utilities. While this enables easy decentralization of the learned policy, the restricted joint action value function can prevent them from solving tasks that require significant coordination...conference paper 2021

Peng, Q. (author), Vermolen, F.J. (author)Deep tissue injury is often followed by contraction of the scar tissue. This contraction occurs as a result of pulling forces that are exerted by fibroblasts (skin cells). We consider a cell-based approach to simulate the contraction behavior of the skin. Since the cells are much smaller than the wound region, we model cellular forces by...conference paper 2020

Tsouvalas, A. (author), Peng, Y. (author), Metrikine, A. (author)The prediction of underwater noise and the assessment of the influencing factors on noise transmission are significant for the control and mitigation of the noise generated by offshore pile driving. This paper presents a coupled two-step approach for modelling the underwater noise from offshore pile driving, with the focus being placed on...conference paper 2021

Wuite, F.G.E. (author), Peng, Zhikai (author), Kim, K.J. (author), Lugten, M.C. (author), Tenpierik, M.J. (author)This study aims to evaluate the impact of different urban building geometries (six courtyards, two canyons, two slabs) on heat mitigation and aircraft noise attenuation, in order to support an evidence-based retrofit plan for future airport neighborhoods. Using ’Pachyderm + ENVI-met simulations + field measurements’, we found that the slanted...conference paper 2024

Kim, K.J. (author), Lugten, M.C. (author), Wuite, F.G.E. (author), Peng, Zhikai (author), Tenpierik, M.J. (author)Analyzing the impact of aircraft noise on urban areas requires specific consideration of sound propagation over long distances, which is not typically covered by tools designed for indoor acoustics. Although it is unclear to what extent existing parametric tools that combine 3D modeling and acoustic simulation can accurately replicate these...conference paper 2024

Peng, K. (author), Avallone, F. (author), Kotsonis, M. (author)Plasma-based flow control poses a simple and robust technique for transition delay on swept wings. However, a clear understanding of how plasma actuators affect crossflow instabilities is necessary to develop and mature crossflow control based on plasma actuators. In this paper, the design of a new swept wing model optimised for the study of...conference paper 2021

A near-source module is adopted to capture the interaction between the pile, fluid and soil, which is based on a previously developed semi-analytical vibro-acoustic model. This module primarily aims...conference paper 2020
