van Bilsen, Daniël (author), Huang, Yilin (author), Li, Fen (author)China is undergoing large changes to tackle carbon dioxide emissions and air pollution. While the top-down governance allows for clear setting of emission reduction targets for industrial sectors and major cities, reducing emissions in residential sectors in smaller (the so-called low-tier) cities remain challenging and often unaddressed. This...conference paper 2020

Boricic, Aleksandar (author), Rueda, José L. (author), Popov, M. (author)Renewable energy sources (RES) penetrate power grids at all voltage levels. A large number of RES units are connected to medium-voltage (MV) and low-voltage (LV) levels resulting in a significant share of overall generation. Therefore, the dynamic behavior of such distribution grids should be thoroughly examined. The goal of this paper is to...conference paper 2020

Wallace, Mark (author), Yorke-Smith, N. (author)The cyclic hoist scheduling problem (CHSP) is a well-studied optimisation problem due to its importance in industry. Despite the wide range of solving techniques applied to the CHSP and its variants, the models have remained complicated and inflexible, or have failed to scale up with larger problem instances. This article re-examines...journal article 2020

(author), Gabriele, Domenico (author)Bigels are interesting semisolid formulations with better properties for different applications such as cosmetics and pharmaceutical systems. Due to the mixing of two phases of different nature (polar and apolar), bigels possess some interesting features like ability to deliver hydrophilic and hydrophobic drugs, better spreadability and water...review 2019

Valle Torre, M. (author), Ye, Mengmeng (author), Lofi, C. (author)Effectively modelling and querying experience items like movies, books, or games in databases is challenging because these items are better described by their resulting user experience or perceived properties than by factual attributes. However, such information is often subjective, disputed, or unclear. Thus, social judgments like comments,...conference paper 2019

van Breugel, K. (author)The world’s infrastructure is vital for providing accommodation and mobility for people. Although it is obvious that the construction industry has been crucial for realizing building and civil infrastructures, it is also clear that building activities have a big impact on the environment. Still growing and developing societies and economies...journal article 2019

Peeters, J.W.R. (author), Rohde, M. (author)A new friction-heat transfer analogy for the prediction of heat transfer to turbulent fluids at supercritical pressure is presented. This analogy is based on the observation that the predominent events that determine the turbulent heat flux known as hot ejections and cold sweeps have different thermophysical properties. This observation is...journal article 2019

Bahrami, Abbas (author), Yazdan Mehr, M. (author)Isothermal ageing of Al–Mg–Si alloys, stored at room temperature for more than 5 months, is associated with an unexpected significant increase in the overall electrical resistivity. This unexpected anomalous increase is not observed in alloys with shorter storage (natural ageing) times. This phenomenon is explained with a scenario, based on...journal article 2019

Huisman, B.J.A. (author), Walstra, Dirk Jan R. (author), Radermacher, Max (author), de Schipper, M.A. (author), Ruessink, B. Gerben (author)Shoreface nourishments are commonly applied for coastal maintenance, but their behaviour is not well understood. Bathymetric data of 19 shoreface nourishments located at alongshore uniform sections of the Dutch coast were therefore analyzed and used to validate an efficient method for predicting the erosion of shoreface nourishments. Data shows...journal article 2019

(author)Multiphasic fermentations where an organic phase is spontaneously formed or when it is added for product removal are commonly used for production of valuable compounds. The turbulent conditions and the presence of surface-active compounds (SACs) during fermentation create a stable emulsion difficult to separate. A gas bubble/oil droplet...journal article 2019

Theocharis, A. (author), Popov, M. (author)In this paper, a piece-wise linearized transformer winding model is proposed for transient internal voltage distribution computations. In particular, the model is based on the linearization of the primitive non-linear, frequency dependent and invariant matrix of voltage distribution factors. This primitive matrix is utilized as a pattern from...conference paper 2019

Huang, X. (author)The technique called "flameless combustion", also denoted as "MILD" combustion, was developed to reduce the nitrogen oxides (NOx) emission in the combustion process. The term "flameless" refers to the low visibility of the flame. The technique is particularly of interest when hot exhaust gas is used to preheat inlet air to high temperature. The...doctoral thesis 2018

Maas, J.B. (author), van Gent, R.N.H.W. (author), Hoekstra, J.M. (author)Object tracking is performed when surveillance applications have multiple observations of an object over time. An example of such a surveillance application is mounting a wideangle Frequency Modulated Continuous Wave (FMCW) radar system on board of a General Aviation aircraft. This is done in order to observe its environment in detail, including...conference paper 2018

Mao, W. (author), Ma, Yao (author), Sloof, W.G. (author)A multi-element and multi-phase internal oxidation model that couples thermodynamics with kinetics is developed to predict the internal oxidation behaviour of Fe–Mn–Cr steels as a function of annealing time and oxygen partial pressure. To validate the simulation results, selected Fe–Mn–Cr steels were annealed at 950 °C for 1–16 h in a gas...journal article 2018

Holicki, M.E. (author), Drijkoningen, G.G. (author), Wapenaar, C.P.A. (author)Up–down wavefield decomposition is effectuated by a scaled addition or subtraction of the pressure and vertical particle velocity, generally on horizontal or vertical surfaces, and works well for data given on such surfaces. The method, however, is not applicable to decomposing a wavefield when it is given at one instance in time, i.e. on...journal article 2018
