Bijl, Jorn (author)Green hydrogen plays an important role in the energy transition. It can function as a storage medium, as well as a replacement for fossil fuels in transport or high-temperature heat processes. However, the economic feasibility of electrolysers has proved to be a problem. Even though a lot of research has been done to the electrolysis technology,...master thesis 2023

Bijl, Robin (author)The ever-increasing demand for computing has led to the need for specialized heterogeneous hardware, and the frameworks required to utilize them. Besides the traditional central processing units, more and more programs will make use of specialized hardware to accelerate computations. However, the increase in computing also leads to shorter mean...master thesis 2023

Bijl, Romy (author)With almost 110 million inhabitants, Ethiopia is the largest and most populous<br/>country in the Horn of Africa. In the current trend of global urbanization, Ethiopia’s cities are rapidly growing. A tripling of the urban population is to be expected in 2050, putting a big pressure on the housing stock and employment opportunities. Addis Ababa,...master thesis 2021

Bouwstra, Pieter S. (author), Correia, Gonçalo (author), Bijl, Peter (author), Negenborn, R.R. (author), Atasoy, B. (author)The quality of the delivery service is a crucial asset for an e-grocer to create and maintain a loyal customer-base. With the rapid market growth of e-grocers over the last decade, there is an urgent need for e-grocer specific routing systems. Although stochastic and dynamic routing models are studied for a wide range of applications, e...conference paper 2021

Dalmijn, Menno (author), Atasoy, B. (author), Bijl, Peter (author), Negenborn, R.R. (author)This paper proposes a model for charge scheduling of electric vehicles in last-mile distribution that takes into account battery degradation. A mixed integer linear programming formulation is proposed that minimizes labor, battery degradation and time-dependent energy costs. The benefit of implementing charge schedule optimization is assessed...conference paper 2020

Young On, Ruben (author), van de Kuilen, Richard (author), Bijl, Robin (author), Leistra, Hidde (author), Jugariu, Timo (author)Grading exams is a time-consuming activity for teachers. Zesje is an open-source tool created to aid teach-ers in exam grading and streamline the grading process. Zesje currently uses computer vision techniques torealign images, and automatically find student numbers. However, teachers can currently only use Zesje tograde questions manually....bachelor thesis 2019

Mehta, D. (author), Zhang, Y. (author), van Zuijlen, A.H. (author), Bijl, H. (author)Despite advances in turbulence modelling, the Smagorinsky model remains a popular choice for large eddy simulation (LES) due to its simplicity and ease of use. The dissipation in turbulence energy that the model introduces, is proportional to the Smagorinsky constant, of which many different values have been proposed. These values have been...journal article 2019

Bijl, H.J. (author), Schön, Thomas B. (author)The linear–quadratic-Gaussian (LQG) control paradigm is well-known in literature. The strategy of minimizing the cost function is available, both for the case where the state is known and where it is estimated through an observer. The situation is different when the cost function has an exponential discount factor, also known as a prescribed...journal article 2019

Bijl, H.J. (author)Wind turbines are growing bigger to becomemore cost-efficient. This does increase the severity of the vibrations that are present in the turbine blades, both due to predictable effects like wind shear and tower shadow, and due to less predictable effects like turbulence and flutter. If wind turbines are to become bigger and more cost-efficient,...doctoral thesis 2018

(author), Bijl, E (author)Single layer concrete armor systems are being widely used nowadays in the design of rubble mound breakwaters. Recently, a new concrete armor unit has been developed and applied as single layer armor system in the repair works of one damaged breakwater at Al Fujeirah, UAE. It has a symmetrical shape, in contrast to most other units. Modern...journal article 2017

Florentie, L. (author), van Zuijlen, A.H. (author), Hulshoff, S.J. (author), Bijl, H. (author)Vortex generators (VGs) are a widely used means of flow control, and predictions of their influence are vital for efficient designs. However, accurate CFD simulations of their effect on the flow field by means of a body fitted mesh are computationally expensive. Therefore the BAY and jBAY models, which represent the effect of VGs on the flow...journal article 2017

Kaja Kamaludeen, Shaafi M. (author), van Zuijlen, A.H. (author), Bijl, H. (author)High computational cost associated with the high fidelity wake models such as RANS or LES serves as a primary bottleneck to perform a direct high fidelity wind farm layout optimization (WFLO) using accurate CFD based wake models. Therefore, a surrogate based multi-fidelity WFLO methodology (SWFLO) is proposed. The surrogate model is built...journal article 2016
