Keijzer, Alexander (author)Experience replay for off-policy reinforcement learning has been shown to improve sample efficiency and stabilize training. However, typical uniformly sampled replay includes many irrelevant samples for the agent to reach good performance. We introduce Action Sensitive Experience Replay (ASER), a method to prioritize samples in the replay buffer...master thesis 2023

Lende, Knut Roar (author)Linear Parameter-Varying (LPV) systems can be used as a bridge to extend the well studied model based control methods of Linear Time-Invariant systems to certain nonlinear systems. Despite significant attention in literature over the last two decades, finding an efficient global state space identification algorithm remains an open problem....master thesis 2023

Beragnoli, Matteo (author)The intensification of human and industrial activities since the Industrial Revolution has led to a significant increase in global greenhouse gas emissions, posing a threat to life on our planet. As the transportation sector contributes to 23% of global CO2 emissions, it is imperative to reduce its carbon footprint. Developing a worldwide...master thesis 2023

IOANNIDIS, MENANDROS (author)Current research conducted at TU Delft focused on utilizing structural Topology Optimization (TO) for designing large monolithic cast glass structures with maximum stiffness and minimum mass. These structures demonstrated improved manufacturability in terms of time, energy, and cost efficiency due to their mass efficiency, which results in...master thesis 2023

Moens, Tieme (author)Flying drones have been a well-established field of engineering for many years now. With the wave of bio-inspired design came the idea of flapping wing micro air vehicles (FWMAVs). These drones use flapping wings instead of fixed or rotary wings to generate their lift, giving them the potential for agile movement and application in confined...master thesis 2023

Fan, Haochun (author)Class-D amplifiers have gained significant importance in automotive applications due to its high efficiency. However, to meet strict electromagnetic interference (EMI) requirements, an LC filter is necessary, which, unfortunately, introduces nonlinearity to the system. This project proposes an architecture by implementing a dual voltage/current...master thesis 2023

Mihalevschi, Anton (author)Urbanization, a desire for a reduction of CO2 and a need for a more efficient use of space are likely to greatly increase demand for rail travel in the coming decades. To improve railway capacity, extra infrastructure can be built, or existing track can be optimized. A silo analogy provides an interesting idea for an integral approach to network...master thesis 2023

Carrion Aretxabala, B.I. (author)A very large storm hit the coasts of The Netherlands-and most of north-west Europe-during the evening of the 5th of December 2013. The Sinterklaas storm, as it was later known, induced extremely high water levels and substantial dune erosion all along the Dutch coastline. In this thesis the morphological impact of the Sinterklaas storm at one...master thesis 2015

Mahalingam, A. (author)Developments in the electricity system need to accommodate the pressure of steadily rising demand, advanced technology integration in addition to increasing penetration levels of renewable energy sources (RES) and distributed generation (DG). As such, European energy policy for 2020 is aimed at reducing greenhouses gases by 20%, increasing RES...master thesis 2013

Vidalis, I. (author)Trimethylene glycol dimethyl ether (triglyme), a Polyethylene glycol (PEG)-like hydrophilic polymer, was deposited by plasma polymerization to reduce RO membrane’s organic fouling tendency. This method has the great advantage of achieving modification in one single step. A series of plasma deposition experiments were undertaken. The successful...master thesis 2010

Hartwigsen, M. (author)In June 2015, Amsterdam Airport Schiphol (AAS) changed its security check at the gate to centralized security for the entire airport. New security lanes were developed by Scarabee Aviation Group for those centralized areas to increase security, efficiency, passenger flow and experience. Lots of customer research about passenger experience is...master thesis 2016

Bakker, Marieke (author)Amazing Grace will be needed for the removal of offshore platforms that are out of Pioneering Spirit 's reach. The base case design of Amazing Grace is an enlarged version of Pioneering Spirit (Figure 1). Amazing Grace uses mainly Quick drop Ballast tanks, releasing a lot of water at once, for lifting. Pioneering Spirit uses mainly a pneumatic...master thesis 2019

Arens, Jesse (author)Machine learning is becoming an increasingly important tool for climate scientists, but hampered by lacking uncertainty quantification. Here, a machine learning approach for detecting patterns indicating a changing climate is combined with probabilistic modelling to retrieve uncertainty values. We train neural networks on climate model...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
