Aniche, Maurício (author), Bavota, Gabriele (author), Treude, Christoph (author), Gerosa, Marco Aurélio (author), van Deursen, A. (author)Previous studies have shown the negative effects that low-quality code can have on maintainability proxies, such as code change- and defect-proneness. One of the symptoms for low-quality code are code smells, defined as sub-optimal implementation choices. While this definition is quite general and seems to suggest a wide spectrum of smells that...journal article 2018

Wang, Weiming (author), Liu, Yong-Jin (author), Wu, J. (author), Tian, Shengjing (author), Wang, C.C. (author), Liu, Ligang (author), Liu, Xiuping (author)Offsetting-based hollowing is a solid modeling operation widely used in 3D printing, which can change the model's physical properties and reduce the weight by generating voids inside a model. However, a hollowing operation can lead to additional supporting structures for fabrication in interior voids, which cannot be removed. As a consequence...journal article 2018

Yi, Ran (author), Wu, Chenming (author), Liu, Yong-Jin (author), He, Ying (author), Wang, C.C. (author)This paper presents a 3-D printing system that uses a low-cost off-the-shelf consumer projector to fabricate large models. Compared with traditional digital light processing (DLP) 3-D printers using a single vertical carriage, the platform of our DLP 3-D printer using delta mechanism can also move horizontally in the plane. We show that this...journal article 2018

Zhu, S. (author), Pozarlik, Artur (author), Roekaerts, D.J.E.M. (author), Correia Rodrigues, H.R. (author), van der Meer, Theo (author)In the past 25 years high temperature air combustion (HiTAC) technology has been proved and utilized in industry as a promising way to increase thermal efficiency, create a relatively uniform temperature distribution, and reduce emissions of harmful pollutants such as NO<sub>X</sub> and CO. However, due to the complexity of fuel-oil...journal article 2018

Roelvink, D. (author), McCall, Robert (author), Mehvar, Seyedabdolhossein (author), Nederhoff, Kees (author), Dastgheib, Ali (author)In predicting storm impacts on sandy coasts, possibly with structures, accurate runup and overtopping simulation is an important aspect. Recent investigations (Stockdon et al., 2014; Palmsten and Splinter, 2016) show that despite accurate predictions of the morphodynamics of dissipative sandy beaches, the XBeach model (Roelvink et al., 2009)...journal article 2018

Jordan Prunera, J.M. (author), Torreño, Alejandro (author), de Weerdt, M.M. (author), Onaindia, Eva (author)When self-interested agents plan individually, interactions that prevent them from executing their actions as planned may arise. In these coordination problems, game-theoretic planning can be used to enhance the agents’ strategic behavior considering the interactions as part of the agents’ utility. In this work, we define a general-sum game...journal article 2018

Zhong, Zhichao (author), Aveyard, R.A. (author), Rieger, B. (author), Bals, Sara (author), Palenstijn, Willem Jan (author), Batenburg, K. Joost (author)HAADF-STEM tomography is a common technique for characterizing the three-dimensional morphology of nanomaterials. In conventional tomographic reconstruction algorithms, the image intensity is assumed to be a linear projection of a physical property of the specimen. However, this assumption of linearity is not completely valid due to the...journal article 2018

Trajanovski, S. (author), Kuipers, F.A. (author), Hayel, Yezekael (author), Altman, Eitan (author), Van Mieghem, P.F.A. (author)Designing an optimal network topology while balancing multiple, possibly conflicting objectives like cost, performance, and resiliency to viruses is a challenging endeavor, let alone in the case of decentralized network formation. We therefore propose a game-formation technique where each player aims to minimize its cost in installing links,...journal article 2018

Steinbrink, C. (author), van der Meer, A.A. (author), Cvetkovic, M. (author), Babazadeh, D. (author), Rohjans, S. (author), Palensky, P. (author), Lehnhoff, S. (author)Evaluating new technological developments for energy systems is becoming more and more complex. The overall application environment is a continuously growing and interconnected cyber-physical system so that analytical assessment is practically impossible to realize. Consequently, new solutions must be evaluated in simulation studies. Due to...journal article 2018

Khakzad, N. (author), Landucci, Gabriele (author), Cozzani, Valerio (author), Reniers, G.L.L.M.E. (author), Pasman, HJ (author)The propagation of fire-induced domino effects in chemical plants largely depends on the primary fire scenario, on separation distances between the units, and on the presence of fire protection barriers. Passive and active safety barriers are widely employed to prevent or delay the initiation or propagation of domino effects. In the present...journal article 2018

(author), Dahlbo, Helena (author), Aminoff, Anna (author)The circular economy (CE) can be a driver for sustainability and CE can be promoted and supported by the creation of new and innovative business models, which embed CE principles into their value propositions throughout the value chains. This study focuses on the environmental value propositions of the CE business models. The term environmental...journal article 2018

(author)We assess the effect of substrate heterogeneity on the metabolic response of P. chrysogenum in industrial bioreactors via the coupling of a 9-pool metabolic model with Euler-Lagrange CFD simulations. In this work, we outline how this coupled hydrodynamic-metabolic modeling can be utilized in 5 steps. (1) A model response study with a fixed...journal article 2018

Sahai, A.K. (author), Snellen, M. (author), Simons, D.G. (author)This paper presents an approach with which perceived audible differences in aircraft sounds can be quantified and presented in an objective manner. The objective quantification of the subjectively heard audible differences is intended to serve two primary goals. It can firstly enable developers of auralization technology to make the auralized...journal article 2018

Hendriks, A.T.W.M. (author), van Lier, J.B. (author), de Kreuk, M.K. (author)Fermentation and anaerobic digestion of organic waste and wastewater is broadly studied and applied. Despite widely available results and data for these processes, comparison of the generated results in literature is difficult. Not only due to the used variety of process conditions, but also because of the many different growth media that are...journal article 2018
