Larsen, R.B. (author), Sprokkereef, Jasper M. (author), Atasoy, B. (author), Negenborn, R.R. (author)It is desirable to improve the efficiency of container transport both from an economical and an environmental point of view, as increased efficiency decreases costs and emissions per transported container. Modern transport schemes, such as synchromodal transport, use a-modal bookings to increase the flexibility of the transport providers where...conference paper 2021

Reitebuch, Ulrich (author), Skrodzki, M. (author), Polthier, Konrad (author)The approximation of a golden logarithmic spiral by quarter circles is well known. Starting from this, we show that any logarithmic spiral can be approximated by quarter circles in a similar way. Using our construction on a rectangle with aspect ratio √휙 and performing a coordinate reparametrization, we obtain an aesthetic partition of the plane...conference paper 2021

Qiu, Xiujiao (author), Chen, J. (author), Ye, G. (author), De Schutter, Geert (author)ASR (alkali-silica reaction) is one of the toughest durability problems in engineering. However, the damage induced by ASR is still fairly unpredictable due to the lack of microstructural information of cement-based materials affected by ASR, while the microstructure determines the global performance. In order to fill this gap, a multiscale...conference paper 2021

Wang, F. (author), Leus, G.J.T. (author)In this paper we consider the problem of joint wideband spectrum sensing and direction-of-arrival (DoA) estimation, where a number of uncorrelated narrowband sources spread over a wide frequency band impinge on a sparse linear array (SLA). To overcome the sampling rate bottleneck for wideband spectrum sensing, we rely on sub-Nyquist sampling for...conference paper 2021

Kara, A. (author), van Oosterom, P.J.M. (author), Kathmann, Ruud (author), Lemmen, Christiaan (author)The timely and effective dissemination of property values is an essential part of a transparent and efficient property valuation system as property values are required in several land administration processes, such as land acquisition, taxation, transaction, consolidation, readjustment and transformation. In the last decade, a web-based data...conference paper 2021

Brans, S. (author), Rinne, Andre (author), Kana, A.A. (author)Service Operation Vessels (SOVs) are purpose-built maintenance vessels that provide high accessibility to far-offshore wind turbines, but they lack multitasking capabilities. Its daughter craft (DC) is a valu-able asset for unplanned maintenance in the summer when it can operate safely, but it is often not deployable during rough weather...conference paper 2021

Ye, Hanting (author), Wang, Q. (author)We are now witnessing a trend of realizing full-screen on electronic devices such as smartphones to maximize their screen-to-body ratio for a better user experience. Thus the bezel/narrow-bezel on today's devices to host various line-of-sight sensors would disappear. This trend not only is forcing sensors like the front cameras to be placed...conference paper 2021

Novas, María (author), Pllumbi, Dorina (author)Shëmti and feísmo are the two names given respectively in the Albanian and Galician languages to stigmatize this unruly built environment: It is considered a material expression of both constructed and internalized myth of being the underdeveloped peoples in the European periphery.<br/>This paper aims to explore how this stigmatization has been...conference paper 2021

Skrodzki, M. (author), Reitebuch, Ulrich (author), Zimmermann, Eric (author)In this paper, we are interested in classifying the different arising (topological) structures of three-dimensional Turing-like patterns. By providing examples for the different structures, we confirm a conjecture regarding these structures within the setup of three-dimensional Turing-like pattern. Furthermore, we investigate how these...conference paper 2021

Seyffert, Harleigh C. (author), Kana, A.A. (author), Troesch, Armin W. (author)This paper examines the performance of 6 stiffened ship panel designs in different operational profiles. The main question of interest is: which sea states will lead to the worst panel performances in terms of reliability? As stiffened panel collapse is governed by combined lateral and in-plane loading effects (non-linear functions of the...conference paper 2021

Schwind, Nicolas (author), Inoue, Katsumi (author), Demirović, E. (author)Team formation is the problem of deploying the least expensive team of agents while covering a set of skills. Once a team has been formed, some of the agents considered at start may be finally defective and some skills may become uncovered. Two solution concepts have been recently introduced to deal with this issue in a proactive manner: one may...conference paper 2021

Parkin, S.E. (author), Arnell, Simon (author), Ward, Jeremy (author)Leaders of organisations must make investment decisions relating to the security of their organisation. This often happens through consultation with a security specialist. Consultations may be regarded as conversations taking place in a trading zone between the two domains. We propose that supporting the trading zone is a route to sustainable,...conference paper 2021

Golchin, A. (author), Vardon, P.J. (author), Hicks, M.A. (author), Coombs, William M. (author), Pantev, I.A. (author)The numerical implementation of a recently developed thermomechanical constitutive model for fine-grained soils based on hyperelasticity-hyperplasticity theory (Golchin et al. 2020), is presented. A new unconventional implicit stress return mapping algorithm, compatible with elasticity derived from Gibbs (complementary) energy potential, in...conference paper 2021

Becker, Leonard (author), Hohlfeld, Oliver (author), Smaragdakis, G. (author)With the increasing cloud usage for access to fast and well-connected computational power, cloud outages have also become a growing risk for businesses and individuals alike. We derive a method to analyze publicly available BGP data to measure the visibility of cloud providers' outages on the Internet control plane. We then utilize this...conference paper 2021

Gonzalez-Longatt, Francisco (author), Rueda, José L. (author), Palensky, P. (author), Chamorro, Harold R. (author), Sood, Vijay K. (author)Inverter based generation (IBG) is a necessary technology in the energy transition and reaching ambitious objectives of zero-net emission. However, the colossal penetration of IBG may create several issues. Using Voltage source converters (VSCs) equipped with the so-called grid forming control is thought of as a long-term solution of IBG...conference paper 2021

Kolff, Maurice (author), Venrooij, J. (author), Schwienbacher, Markus (author), Pool, D.M. (author), Mulder, Max (author)When designing driving simulation experiments with motion cueing, it is often necessary to make choices between Motion Cueing Algorithms (MCAs) without being fully able to know how well an MCA will perform during the experiment. Choices between MCAs can therefore be greatly supported by previous measurements or predictions of motion cueing...conference paper 2021

Derakhshanfar, P. (author), Devroey, Xavier (author), Zaidman, A.E. (author)Search-based techniques have been widely used for white-box test generation. Many of these approaches rely on the approach level and branch distance heuristics to guide the search process and generate test cases with high line and branch coverage. Despite the positive results achieved by these two heuristics, they only use the information...conference paper 2020
