Zheng, Yi (author)Silicon heterojunction (SHJ) solar cell technology is one of the most promising PV technologies because of its high power conversion efficiencies, simple fabrication process and low manufacturing cost. The current world record efficiency of SHJ solar cell reaches up to 26.81%. SHJ solar cell produces the highest VOC over 750 mV among the c-Si...master thesis 2023

Zandstra, Joery (author)Currently, the electricity grid in the Netherlands is reaching its capacity, resulting in congestion issues. One of the factors that causes the electricity grid to become overloaded is the increasing use of EVs (electric vehicles). A situation in which a large number of EV users in a certain area charge their EV at the same time can...master thesis 2023

Zeng, Sijun (author)Site characterization is indispensable in the design phase of geotechnical engineering projects. As a key factor in site characterization, the characterization of soil undrained shear strength (S<sub>u</sub>) is always in the spotlight. Various methods, including laboratory and in-situ tests, have been developed to measure S<sub>u</sub>....master thesis 2023

Sharma, Devansh (author)Low-cost multijunction photovoltaic devices are the next step in the solar energy revolution. Adding a bottom junction with a low bandgap energy material through plasma-enhanced chemical vapour deposition (PECVD) processing could provide a low-cost boost in conversion efficiency. A logical candidate for this low-bandgap material is germanium. A...master thesis 2023

Schuurman, Kevin (author)The use of deep learning in global weather forecasting has shown significant promise in improving both forecasting accuracy and speed. Traditional numerical weather prediction models have gradually improved forecasting skills but at the cost of increased computational complexity. In contrast, new deep learning models, trained directly on...master thesis 2023

Gründemann, Axel (author)This paper investigates the effect of intrinsic muscle stiffness on neural control parameters in biological musculoskeletal control of stabilisation or reaching tasks. Current model implementations of intrinsic muscle properties are highly simplified, limiting their accuracy in replicating experimental short-range stiffness (SRS) behaviour,...master thesis 2023

(author), Arcos-Hernandez, Monica (author), Dijkstra, Jelmer (author), de Vries, Erik (author)Past studies have repeatedly demonstrated the technical feasibility to produce polyhydroxyalkanoate (PHA) using bacterial biomass of mixed microbial cultures (MMCs). Commercial quality grades of poly(3-hydroxybutyrate-co-3-hydroxyvalerate), PHBV, can be produced with control of average monomer composition. However, demonstration of PHBV...journal article 2023

Schwietert, T.K. (author)Solid-state batteries have the promise to outperformconventional Li-ion batteries. Solid electrolytes are safer, as the solids used are generally not combustible, and especially if Li-metal anodes are enabled, higher energy densities can be obtained. However, solidstate batteries still have challenges to overcome. In this thesis the origins of...doctoral thesis 2022

Zaidi, Amir (author)In the field of computer vision, the difficulty of processing the illumination in an arbitrary scene creates complications for a machine's understanding of the scene. Computer vision algorithms commonly use input images acquired by a camera, where the only measured quantity is the amount of light the camera's sensor receives without any...master thesis 2022

Eggers, Yvonne (author)Event cameras and spiking neural networks (SNNs) allow for a highly bio-inspired, low-latency and power efficient implementation of optic flow estimation. Just recently, a hierarchical SNN was proposed in which motion selectivity is learned from raw event data in an unsupervised manner using spike-timing-dependent plasticity (STDP). However,...master thesis 2022

Klazinga, Rembrandt (author)Autoencoders seek to encode their input into a bottleneck of latent neurons, and then decode it to reconstruct the input. However, if the input data has an intrinsic dimension (ID) smaller than the number of latent neurons in the bottleneck, this encoding becomes redundant. <br/>In this paper, we study using the Early-Bird (EB) technique, a...master thesis 2022

Fragasso, A. (author)At first glance nanopores may appear simple, almost intuitive, to understand given that they are, quite literally, ‘just’ very small pores in a membrane. In fact, one may even wonder why at all we need trained scientists to study such seemingly simple entities. The short answer is that nanopores, as the word suggests, are nanoscale entities and,...doctoral thesis 2021

Deciding the right use: Making the intrinsic land value creation explicit in port area redevelopmentBal, Jamie (author)The redevelopment of brownfield sites such as port, industrial or business locations are designated for redevelopment, mostly for residential or commercial use. However, waterfront redevelopment sites are amongst the most complex to develop (Daamen, 2007). That is why it is important to understand why we choose for redevelopment to new or other...master thesis 2021

Rouvoet, A.J. (author), Krebbers, R.J. (author), Visser, Eelco (author)To avoid compilation errors it is desirable to verify that a compiler is type correct-i.e., given well-typed source code, it always outputs well-typed target code. This can be done intrinsically by implementing it as a function in a dependently typed programming language, such as Agda. This function manipulates data types of well-typed source...journal article 2021

Bakker, Floor (author)To exploit its socio-economic functions, engineering measures are regularly applied in estuaries. Estuaries are, however, known to be very complex systems. Stemming from this complexity is the generation of a so-called estuarine turbidity maximum (ETM), which poses great siltation problems to the engineering measures. An engineering measure,...master thesis 2020
