Tseremoglou, I. (author), Santos, Bruno F. (author)In the Condition-Based Maintenance (CBM) context, the definition of optimal maintenance plans for an aircraft fleet depends on an efficient integration of : (i) the probabilistic predictions of the health condition of the components and (ii) the stochastic arrival of the corrective maintenance tasks, together with consideration of the...journal article 2024

de Gooijer, Jessica (author)Reinforcement learning, especially deep reinforcement learning, has made many advances in the last decade. Similarly, great strides have been made in multi-agent reinforcement learning. Systems of cooperative autonomous robots are increasingly being used, for which multi-agent reinforcement learning can be used as a training method. However, the...master thesis 2023

de Rouw, Lieke (author)INTRODUCTION Surgical counting of instruments forms a crucial part of safety procedures in the operating room (OR). This process has remained primitive without technological support. The manual count process is time-consuming and places heavy cognitive demands on nurses. Current technological approaches fail to detect the exact and detailed...master thesis 2023

Plămădeală, Ion (author)The wake effect which is turbulence behind a wind turbine created when it extracts energy negatively impacts the power output of the downstream turbines. Active Wake Control can mitigate this effect, by rotating some turbines away from the wind. Previous research applied single agent reinforcement learning to apply Active Wake Control, show- ing...bachelor thesis 2023

Çil, Ata (author)Autonomous driving is a complex problem that can potentially be solved using artificial intelligence. The complexity stems from the system's need to understand the surroundings and make appropriate decisions. However, there are various challenges in constructing such a sophisticated system. One of the main challenges is to make the agent learn...bachelor thesis 2023

Tong, Mathew (author)According to the Oxford Learner’s Dictionaries, the notion of “space” can be read in several ways, of what is the five general understandings of it would be: outside earth’s atmosphere, empty area, period, freedom, and lastly, where things exist/move. With the speed, amount of information, and technology we are currently facing in the 21st...master thesis 2023

Machado Lima de Camargo, C. (author)As a result of climate change, sea level is changing all over the world at unprecedented rates. Sea-level change can have significant impacts on coastal communities, infrastructure and global economy, as most of the major cities are located near to or at the coast. Rising sea levels can lead to, for instance, more severe and more frequent...doctoral thesis 2023

Klein Holkenborg, Emie (author)Small to medium-sized man-made freshwater reservoir are a reliable source for drinking water supply, hydropower generation and irrigation purposes worldwide. However, water volumes in these reservoirs can be significantly affected by prolonged droughts, resulting in severe impacts on society (Kozacek, 2014; Mahr, 2018). To mitigate the impact of...master thesis 2023

Knoppert, Sammie (author)In the last decades, climate change is causing our environment to change rapidly, unprecedented in recent history. Civil engineering structures are dependent on the deteriorating environment they are situated in. Changes can cause an increase in loading due to, for example, extreme weather events or alter the structure’s resistance by, for...master thesis 2023

Keijzer, T. (author)Without us realizing it, solutions for safety and security are present all around us. However, everyone has undoubtedly also experienced how inconvenient some safety and security measures can be. For example, think about security checks at the airport, the need to wear a bicycle helmet, or being asked to perform 2-factor authentication to log...doctoral thesis 2023

Tapia Barroso, Roderick (author)Future communication scenarios will require massive Multiple-input multiple-output (MIMO) by the use of multi-beam antenna systems. Maximizing the number of beams for a given antenna size is paramount given that the space allocated to the antenna is often limited. This work aims at evaluating the maximum number of beams by analyzing the SIR in...master thesis 2023

Tseremoglou, I. (author), van Kessel, Paul J. (author), Santos, Bruno F. (author)Condition-based maintenance (CBM) scheduling of an aircraft fleet in a disruptive environment while considering health prognostics for a set of systems is a very complex combinatorial problem, which is becoming more challenging in light of the uncertainty included in health prognostics. This type of problem falls under the broad category of...journal article 2023

Borja Rosales, L.P. (author), Scherpen, Jacquelien M.A. (author), Fujimoto, Kenji (author)In this article, we treat extended balancing for continuous-time linear time-invariant systems. We take a dissipativity perspective, thus, resulting in a characterization in terms of linear matrix inequalities. This perspective is useful for determining a priori error bounds. In addition, we address the problem of structure-preserving model...journal article 2023

Chen, Bei (author), Yu, Xin (author), Dong, Fuqiang (author), Wu, Wenxiu (author), Zu, Yuanzhe (author), Ren, S. (author)High-viscosity modified asphalt (HVMA) is the most commonly applied method in drainage asphalt pavements. However, some disadvantages of hot-mix HVMA, including high energy consumption and unavoidable environmental pollution, should be improved. Therefore, warm-mix additive (WMA) was introduced. In this paper, the effects of WMA on the...journal article 2023
