Lagerweij, Pascal (author)Nowadays, reinforcement learning algorithms on Markov decision processes (MDPs) face computational issues when the state space is large. To reduce this state space of a MDP several state aggregation, or clustering, methodologies have been applied. Recently, a new clustering algorithm has been proposed that is able to cluster states from a single...master thesis 2019

Deen, Gerrit (author)Wind Power Producers (WPP) incur a negative result through mandatory participation on the balancing market. This study analyzes the performance of multiple improved offering strategies for a WPP offering both on the day-ahead market and the balancing market. It does so on revenue, as well as its impact on the grid and electricity market as a...master thesis 2019

Wout, Daan (author)A prevalent approach for learning a control policy in the model-free domain is by engaging Reinforcement Learning (RL). A well known disadvantage of RL is the necessity for extensive amounts of data for a suitable control policy. For systems that concern physical application, acquiring this vast amount of data might take an extraordinary amount...master thesis 2019

Głowacki, Piotr (author)Metamaterials are a new class of materials where the properties crucially depend on the design of the unit cell that is periodically repeated in space. In this study a new metamaterial unit cell concept has been proposed, inspired by a class of space structures known as deployable masts. The ability of these structures to contract to a fraction...master thesis 2019

de Wit, Daan (author)This thesis provides insight into how the design approach, also known as ‘Design Thinking’ could be implemented in infrastructure planning processes. This is done with the objective to prevent premature convergence, which means, too early choosing for a solution by which other valuable alternatives are ‘killed off.’ By preventing premature...master thesis 2019

Renita Danarianti, Renita (author)The rapid growth of commercial drone raises concern regarding its close operation to the public. This research aims to support the development of commercial drone that also align with the concept of responsible research and innovation. To achieve this aim, first, the development of drone technology will be analyzed by identifying the influence...master thesis 2019

Adatrao, S. (author), Sciacchitano, A. (author)A novel approach is introduced that allows the elimination of undesired laser light reflections from particle image velocimetry (PIV) images. The approach relies upon anisotropic diffusion of the light intensity, which is used to generate a background image to be subtracted from the original image. The intensity is diffused only along the...journal article 2019

Majzoub, S. (author), Taouil, M. (author), Hamdioui, S. (author)Standard low power design utilizes a variety of approaches for supply and threshold control to reduce dynamic and idle power. At a very early stage of the design cycle, the V<sub>dd</sub> and V<sub>th</sub> values are estimated, based on the power budget, and then used to scale the delay and estimate the design performance. Furthermore,...journal article 2019

van der Spek, Rutger (author)In this thesis, the relation between the generator of the OrnsteinUhlenbeck process and the Hamiltonian of the quantum harmonic oscillator is used to derive a new understanding of the evolution of certain quantum states. More precisely, we transform the Hamiltonian with respect to the ground state and corresponding eigenvalue to find that it is...bachelor thesis 2019

van Korlaar, Arent (author)Turbulence closure models will continue to be necessary in order to perform computationally affordable simulations in the foreseeable future. It is expected that Reynolds-averaged Navier-Stokes (RANS) turbulence models will still be useful with the further development of the more accurate, but computationally expensive large eddy simulation (LES...master thesis 2019

Gerding, Ditte (author)The purpose of this master thesis is to gather information from current practices and make recommendations to facilitate implementation of circularity in the building process. The past years, circularity has become a popular term in the built environment. This approach prefers a more circular way of perceiving the building process. Literature...master thesis 2019

Bast, Bente (author)As Dutch cities are increasingly looking to transform inner city industrial waterfronts into mixed-use neighbourhoods, the need for good participation processes with existing businesses increases. Although municipalities are aware of this, current participation processes often do not lead to the desired results. Therefore, a structured process...master thesis 2019

Visser, Maaike (author), van der Heijden, Stefan (author), Mironov, Stas (author), Hullegien, Nils (author)The Organic Rankine Cycle Hybrid Integrated Device (ORCHID) is a small scale power plant that is used to study the fundamental gas dynamic behavior of dense organic fluids, as well as the behavior of turbomachinery. In order to draw accurate conclusions about the raw sensor data generated by the ORCHID one has to know when the system is in...bachelor thesis 2019

de Jong, Jarn (author)Quantum computing is a field that shows tremendous possibilities and promise. It can provide an exponential speedup compared to classical computers in many computational problems, including simulations of general quantum mechanical systems, pattern finding and solving linear systems. Quantum computations can be performed by making use of qubits...master thesis 2019

Isufi, E. (author)The necessity to process signals living in non-Euclidean domains, such as signals defined on the top of a graph, has led to the extension of signal processing techniques to the graph setting. Among different approaches, graph signal processing distinguishes itself by providing a Fourier analysis of these signals. Analogously to the Fourier...doctoral thesis 2019

Cornelisse, Erik (author)Within aircraft component MRO industry, companies providing availability contracts are challenged by inherently unpredictable demand patterns and complex time crucial operations. Most prevailing academic literature within the MRO industry has focused on availability models or operations management in repair shops in the past. This study focuses...master thesis 2019

Wegener, F.E. (author), Gonçalves, M. (author), Dankfort, Zoë (author)In this paper on designing organizational processes, we combine insight on reflection-in-action with the role of reflection and experimenting from the organizational routine dynamics literature. Illustrated through a case at a strategy consultancy, we show how a prototyped workshop can elicit reflection-in- action when designing organizational...conference paper 2019

Chang, Z. (author), Zhang, H. (author), Schlangen, E. (author), Šavija, B. (author)The aim of this work is to investigate the fracture process of concrete under various boundary conditions. Although numerous concrete fracture tests have been reported, showing the failure behavior of concrete, their evaluation is ambiguous due to the limitations of specimen size and experimental conditions. Therefore, it is necessary to use...conference paper 2019

Slob, E.C. (author), Zhang, L. (author)Elimination of multiples from acoustic reflection data is important to reduce the effect of their presence in velocity model building and subsequent imaging. Many processing schemes assume only primary reflection events are present in the data. Free-surface multiple elimination is an established technology, but internal multiple elimination is...conference paper 2019
