Peijen, Arjen (author)Topology optimization is a valuable tool for the optimization of all kinds of structures. It can create highly efficient but complex designs. This complexity can make these structures challenging to clean. However, cleanability is often a requirement in, for example, the medical or food industries. Currently, no method exists to reduce the...master thesis 2022

Everse, Luc (author)Neural networks (NNs) have, in recent years, become a major part of modern pattern recognition, and both theoretical and applied research evolve at an astounding pace. NNs are usually trained via gradient descent (GD), but research has shown that GD is not always capable of training very small networks. As a result, networks trained via GD are...master thesis 2022

Smeets, Lucy (author)Sorting systems form an example of event driven systems. These types of systems are referred to as discrete event systems (DES), and they consist of jobs that need to be performed at available resources. In an autonomous sorting system, jobs consist of robots receiving and delivering parcels at the correct locations. With scheduling, optimal...master thesis 2022

de Priester, Costijn (author)This work introduces the Surrogate Advisory System (SAS), a Python package that aims to reduce the existing complexity when working with surrogate-based MDAO systems. SAS automates most of the steps for a CPACS-based MDAO workflow and drastically reduces required efforts to integrate surrogate models within MDAO systems. Key developments...master thesis 2022

de Gruijl, Wouter (author)To make propellers more viable as a greener alternative to jet engines, the issue of propeller noise needs to be addressed. Previous propeller design optimization studies rarely take into account the effects on aerodynamic and aeroacoustic performance due to non-uniform inflow, the type of flow the propeller would experience if it was installed...master thesis 2022

Willemen, Ruben (author)The absolute and relative stability are critical aspects of designing Controlled Motion Systems (CMS). The maximum attainable CMS performance depends highly on the design of the structural part and the actuator and sensor configuration, as mechanical vibrations can endanger stability. This thesis presents a method for designing CMS's using...master thesis 2022

Boudouan, Youssra (author)After water, concrete is the most used substance on the planet. Approximately three tonnes of concrete is produced per person annually (Gagg, 2014). Traditionally, large amounts of Ordinary Portland Cement (OPC) are needed for the production of concrete. The production of OPC is very energy intensive and therefore a major generator of carbon...master thesis 2022
