Rennen, Philipp (author), Gantner, Stefan (author), Dielemans, Gido (author), Bleker, Lazlo (author), Christidi, N. (author), Dörrie, Robin (author), Hojjat, Majid (author), Mai, Inka (author), Popescu, M.A. (author)The research project presented here aims to develop a design-informed manufacturing process for complex concrete shell structures in additive manufacturing and thus overcome limitations of traditional construction methods such as formwork- and labor intensity. To achieve this, an effort was made to merge the two technologies of CNC knitted...journal article 2023

Bentert, Matthias (author), Schestag, J. (author), Sommer, Frank (author)We study a generalization of the classic Spanning Tree problem that allows for a non-uniform failure model. More precisely, edges are either safe or unsafe and we assume that failures only affect unsafe edges. In Unweighted Flexible Graph Connectivity we are given an undirected graph G = (V,E) in which the edge set E is partitioned into a set...conference paper 2023

Lyu, Tianshuai (author), Dorenbos, P. (author), Wei, Zhanhua (author)Developing X-ray charged dosimeters with excellent charge carrier storage capacity and stability is challenging. Such energy storage dosimeters have fascinating use in developing novel applications, for instance, in radiation detection, advanced multimode anti-counterfeiting, and flexible X-ray imaging of curved objects. Herein, novel LiTaO...journal article 2023

Khatami, Mohamad (author), Doniavi, Ali (author), Abazari, Amir Musa (author), Fotouhi, M. (author)This paper presents a new design strategy to improve the flexibility and strength-to-weight ratio of polymeric stents. The proposed design introduces a variable-thickness (VT) stent that outperforms conventional polymeric stents with constant thickness (CT). While polymeric stents offer benefits like flexibility and bioabsorption, their...journal article 2023

Snieder, J. (author), Dielen, Marc (author), van Ostayen, R.A.J. (author)This work presents the development of a numerical model for the elastohydrodynamic lubrication of roll-to-plate nanoimprinting with flexible stamps. Roll-to-plate nanoimprinting is a manufacturing method to replicate micro- and nanotextures on large-area substrates with ultraviolet-curable resins. The roller is equipped with a relatively soft...journal article 2023

Xin, Jianbin (author), Meng, Chuang (author), D'Ariano, Andrea (author), Schulte, F. (author), Peng, Jinzhu (author), Negenborn, R.R. (author)This paper investigates a novel routing problem of a multi-robot station in a manufacturing cell. In the existing literature, the objective is to minimize the cycle time or energy consumption separately. The routing problem considered in this paper aims to reduce the cycle time and energy consumption jointly for each robot while avoiding...journal article 2023

Li, L. (author), Bruninx, K. (author), Tindemans, Simon H. (author)This paper proposes a multi-level segmented tariff to encourage consumers to provide demand response using a battery. The aim of the tariff is to (i) properly reflect consumers’ contribution to the distribution grid cost while ensuring cost recovery for the distribution network operator and (ii) to provide consumers with a financial incentive to...conference paper 2023

van Teeffelen, Jop (author)The demand for online shopping has grown tremendously in the last couple of years. Picnic, a major player in the online grocery industry, is struggling to achieve long-term growth within its current operations. Scheduling and planning are key drivers for maintaining operational efficiency. The Fulfilment Centre (FC) and...master thesis 2022

van Doorn, Victor (author)Future energy systems are expected to rely increasingly more on distributed energy resources (DER). Prosumers that own energy resources such as photovoltaic (PV) generation and energy storage systems, will play a crucial role in the realization of DER’s in future power systems. Limited grid connections due to local electricity congestion make it...master thesis 2022

Gusain, D. (author)The transition to sustainable energy iswell underway and is introducing changes on both sides of the electricity balance scale – generation and demand. On the generation side, emissions-free renewable generation resources such as wind and solar are replacing the pollution-emitting thermal power plants. On the demand side, energy sectors...doctoral thesis 2022

Brok, Leon (author)The La Plata Basin is the second largest drainage basin in South America. The Paraná River, the basin’s main river, discharges into the Río de la Plata estuary in Argentina. In the Lower Paraná Delta, near the deltaic front, a complex system of mostly natural and some man-made channels redistribute a part of the river flow. Like the river and...master thesis 2022

Pearse, Oliver (author)During the start-up and shutdown sequence of rocket engines, immense forces are generated that are required to propel the payload into earth's orbit or outer space. The bulk of the generated forces are in the form of thrust. However, forces are also generated that act perpendicularly to the thrust direction. These side-loads are unwanted...master thesis 2022

Evans, Michael (author), Tindemans, Simon H. (author), Angeli, David (author)This paper proposes a framework for the procurement of flexibility reserve from aggregated storage fleets. It allows for arbitrary tree structures of aggregation hierarchy, as well as easily implementable disaggregation via broadcast dispatch. By coupling discharge and recovery modes, the proposed framework enables full-cycle capacity to be...journal article 2022

Beijaard, Adrian (author)In face of climate change, a large challenge was posed to the construction section as the European Union introduced requirements to reduce CO2 emissions; these must be reduced by 40% before 2030, and all member states have to achieve carbon neutrality by 2050. At the time of writing, the construction industry in the Netherlands is respon¬sible...master thesis 2022

Verbist, Flore (author)The electrification of all sectors is essential to achieve carbon neutrality by 2050. In terms of mobility, many nations around the globe envisage a zero-emission fleet resulting in a massive deployment of Electric Vehicles (EV). Nevertheless, this goes hand-in-hand with some challenges related to congestion and voltage problems in power grids...master thesis 2022

van Hedel, Sjoerd (author)A structure is expected to remain for 30-300 years. Building services are most likely integrated into floors and wear out or become obsolete every 7-15 years (Brand, 1995). Currently, 58% of all timber products are landfilled (Lucas et al., 2017). To ensure timber structures’ long and useful service life, adaptability and integration with...master thesis 2022
