Wilkens, Laurent (author)This work sets out the creation, verification and demonstration of an automated end-to-end tool for the multi-point fluid-dynamic optimization of turbomachinery. Taking into account multiple operating conditions during optimization aims to benefit the overall performance of turbomachines which are characterized by off-design operation and to...master thesis 2022

Mingione, Fabio (author)Reaction wheels are often the main contributor to microvibrations on satellites. These vibrations are a source of pointing errors and therefore need to be limited as much as possible. The miniaturization trend in the space industry and universities fostered the production of very small reaction wheels, suited to Cubesat and PocketQube scales. A...master thesis 2022

Wang, Dandan (author), Xu, Jinlan (author), Gao, Fei (author), Wang, C.C. (author), Gu, Renshu (author), Lin, Fei (author), Rabczuk, Timon (author), Xu, Gang (author)In this paper, a deep learning framework combined with isogeometric analysis (IGA for short) called IGA-Reuse-Net is proposed for efficient reuse of numerical simulation on a set of topology-consistent models. Compared with previous data-driven numerical simulation methods only for simple computational domains, our method can predict high...journal article 2022

Djokikj, Jelena (author), Jovanova, J. (author)The digitalization of the product design process has become the new norm in the engineering design with the development of different CAD software, design analyses tools, and rapid prototyping techniques. More holistic approaches in the product design analyses include modeling of the manufacturing technologies and the entire logistics...journal article 2021

Agromayor, Roberto (author), Anand, N. (author), Müller, Jens Dominik (author), Pini, M. (author), Nord, Lars O. (author)Turbomachinery design is increasingly carried out by means of automated workflows based on high-fidelity physical models and optimization algorithms. The parametrization of the blade geometry is an essential aspect of such workflows because it defines the design space in which an optimal solution can be found. Currently, parametrization...journal article 2021

De Lazzari, Elena (author), van den Boom, S.J. (author), Zhang, J. (author), van Keulen, A. (author), Aragon, A.M. (author)Enriched finite element methods have gained traction in recent years for modeling problems with material interfaces and cracks. By means of enrichment functions that incorporate a priori behavior about the solution, these methods decouple the finite element (FE) discretization from the geometric configuration of such discontinuities. Taking...journal article 2021

Tijs, Kasper (author)The objective of this research is to explore the possibilities in the use of digital twins towards the maintenance and operation of tunnels. This is explored by looking at the end users of the technology, to profile their needs and requirements and consider a digital twin design that focuses on this. This research is the start of a human centred...master thesis 2020

Kouvelas, N. (author), Rao, V.S. (author), Venkatesha Prasad, Ranga Rao (author), Tawde, G.C. (author), Langendoen, K.G. (author)Long Range Wide Area Network (LoRaWAN) covers the needs of energy-constrained IoT-devices for operational longevity and extended communication range in a best-effort fashion. However, Lo- RaWAN’s minimalist design cannot handle the traffic from dense deployments with more than a few hundred devices connected to a single gateway, since each LoRa...conference paper 2020

Zhu, Z. (author), la Rocca, G. (author), Zheng, Yao (author), Chen, Jianjun (author)Routing design of aircraft Electrical Wiring Interconnection System (EWIS) is time-consuming and error-prone. A solution, which automatically routes the EWIS inside the aircraft Digital MockUp (DMU), has been proposed and presented in the previous publications. The DMU, however, includes over-detailed features, which hardly influence the...journal article 2020

Clar, Thibault (author)With the global increase in passenger traffic and growing popularity of long-haul routes over the Asia Pacific region and Atlantic Ocean, the possibility for hypersonic transport could become an attractive option to reduce flight time over long distance from 16-20 hours down to around 4-5 hours. In this thesis, a Multi-Disciplinary Optimisation...master thesis 2019

Tawde, Gauri (author)This work is a study into the channel throughput produced by a single channel LoRaWAN gateway under various traffic load conditions. The use of CSMA protocols has been proposed in heavy traffic conditions when ALOHA protocol starts to fail. Three network scenarios - Centralized, Distributed and Hybrid were envisioned in which p-CSMA and np-CSMA...master thesis 2018

van der Mooren, T.L.A. (author)Digitalization helps companies to become more efficient, therefore new developments should be followed closely. One of these developments is the use of 3D models. An increasing amount of information can be processed by the 3D models. This research will look into one of these developments: Model Based Definition. With Model Based Definition (MBD)...master thesis 2017

Ramkisoen, M.G.W. (author)Fugro GeoServices is currently storing their CAD models of the Petrochemical Industry as attributes of 2D lines in a spatial DBMS. This solution works well for web visualization, but not for performing analyses in 3D. The main objective of this graduation project is to create a 3D spatial DBMS with solid CAD geometries as input. The difficulty...master thesis 2015

(author)We present the preliminary results of a work in progress which aims to obtain a software system able to automatically generate a set of diverse 3D building models with a medium level of detail, that is, more detailed that a mere parallelepiped, but not as detailed as a complete geometric representation of the building. Each building model is...conference paper 2015
