Abad Gonzalez, Jose Antonio (author)Steel trusses are the preferred structures when large distances are required to span due to its lightweight, the reduced deflection and its load bearing capacity. Although nowadays with the help of computational tools more efficient designs can be achieved, the geometrical shape of trusses has barely changed. This is mainly due to the ease of the...master thesis 2020

van Berkel, Thijs (author)A watertaxi can reduce the travel time through the city of Rotterdam in comparison with public transport. To make estimations on the average reduced travel time within Rotterdam, a generic method is developed. This method is capable of finding locations for watertaxi jetties. To achieve this, the watertaxi, public transport, and the walking to...master thesis 2020

Verkamman, Sjors (author)Boost-type power factor correction (PFC) rectifiers can be used in, for example, battery charging systems for Electric Vehicles (EVs). Conventionally available three-phase PFC rectifiers are limited to output 1/3 of the rated power when connected to a single-phase mains. This work presents the research into the single-phase operation of the...master thesis 2020

Sivaramakrishnan, Siddharth (author)Shock mounts are crucial components in reducing the transmissibility of a shock or impact, thereby protecting the objective system. Such shock mounts are application-specific and need a redesign for specific uses. This study establishes a transient nonlinear finite element optimization procedure to design a shock mount for withstanding an...master thesis 2020

van der Niet, Astrid (author)Minimum-time optimisation has been used extensively in motorsports, such as Formula One racing. Using minimum-time optimisation, the ideal racing line as well as control strategies such as braking strategies can be found. This is interesting, as Reijne et al have shown that cyclists apply diverse strategies, specifically during a descent [1]....master thesis 2020

de Vries, Niels (author)Bulk materials such as iron ore transported by bulk carriers are commonly unloaded by the use of grabs. The unloading process is time consuming and increasing the unloading capacity is of big importance for terminals. A validated co-simulation developed by the TU Delft in cooperation with Nemag enables to test grabs in the virtual environment....master thesis 2020

Zeng, Yikai (author)Truck platooning refers to coordinating a group of heavy-duty vehicles at a close inter-vehicle distance to reduce overall fuel consumption. This coordination between trucks is traditionally achieved by adjusting the schedule, velocity, and routines to increase the platooning chances, and thus improve the overall fuel efficiency. However, the...master thesis 2020

Zattoni Scroccaro, Pedro (author)In this thesis, we study Online Convex Optimization algorithms that exploit predictive and/or dynamical information about a problem instance. These features are inspired by recent developments in the Online Mirror Decent literature. When the Player's performance is compared with the best fixed decision in hindsight, we show that it is possible...master thesis 2020

Schröder, Casper (author)Code quality of software products often degrades while they grow. Counteracting the degradation of code quality or improving it requires immense effort. Tools that reduce this effort are a hot topic in software engineering research. Software Modularization in particular aims to aid in the process of improving the quality of code structure, by...master thesis 2020

Vermeulen, Maurice (author)The IMO has proposed Just-In-Time arrivals and services as one of the short-term solutions to reduce greenhouse gas emissions in maritime shipping. The Just-In-Time concept allows vessels to optimize their speed during the voyage. If a vessel earlier knows at which time it is requested to arrive at the pilot boarding place, the vessel can adapt...master thesis 2020

Chaves De Plaza, Nicolas (author)TSNE is a popular technique for visualizing high-dimensional data. It finds a low-dimensional representation of the data, also known as embedding, by optimizing a highly non-linear cost function. The optimization process is done iteratively, often with first-order methods such as gradient descent (GD). The performance of iterative optimization...master thesis 2020
