van Arem, Koen (author)Tandem solar cells are a new type of solar cells that are currently being developed. Soms proporties of these solar cells are variable. In this scription, it is studied how genetic algoritms can be applied to optimize these tandem solar cells. Genetic algoritms are algorithms that find a good solution using the principles of evolution theory. It...bachelor thesis 2021

Storm, Joep (author)Designing engineering structures relies on accurate numerical simulations to predict the behaviour of a structure before its realization. In the design process, many variables influence the final structure. There is an incentive for optimizing the design based on the desire for cheaper structures and less material usage. Although a wide variety...master thesis 2021

Loukogeorgaki, Eva (author), Michailides, Constantine (author), Lavidas, G. (author), Chatjigeorgiou, Ioannis K. (author)In this paper, we determine optimum layouts of a cluster of oblate spheroidal heaving point absorbers in front of a wall, that maximize the annual averaged power absorbed by the cluster, while satisfying specific spatial constraints. An iterative optimization process is developed by coupling a hydrodynamic model with a genetic algorithms solver....conference paper 2021

Baladeh, Aliakbar Eslami (author), Khakzad, N. (author)Complex networks play a vital role in reliability analysis of real-world applications, demanding for precise and accurate analysis methods for optimal allocations of cost and reliability. Since the configuration of a system may change with every feasible solution of cost allocation optimization equation, finding the best arrangement of the...conference paper 2019

Hesam Mahmoudi Nezhad, N. (author), Ghaffarian Niasar, M. (author), Mohammadi Gheidari, A. (author), Hagen, C.W. (author), Kruit, P. (author)In electrostatic charged particle lens design, optimization of a multi-electrode lens with many free optimization parameters is still quite a challenge. A fully automated optimization routine is not yet available, mainly because the lens potential calculations are often done with very time-consuming methods that require meshing of the lens...journal article 2019

van Beurden, Merlijn (author)In my thesis, I have done research into the optimization of stopping patterns and frequencies of public transport services within a network. I have developed a model that takes both passenger and operator costs into account. The model has been run for a small fictional network and for the metro and train network of Amsterdam, to explore how the...master thesis 2017

Ceulemans, B. (author)Currently, only one Standard Instrument Departure (SID) track and one flight procedure is used per runway departure fix combination. In contrast to tailored arrivals, the potential benefit of tailored departures has been left relatively undiscovered. The research objective is to quantify the potential benefit of tailored SID-s and profile...master thesis 2016

De Bokx, R. (author)The recently introduced Linkage Tree Genetic Algorithm (LTGA) has shown to exhibit excellent scalability on a variety of optimization problems. LTGA employs Linkage Trees (LTs) to identify and exploit linkage information between problem variables. In this work we present two parallel implementations of LTGA that enable us to leverage the...master thesis 2015

Oshyani, M.F. (author), Cats, O. (author)Bus travel times are subject to inherent and recurrent uncertainties. A real-time prediction scheme regarding how the transit system evolves will potentially facilitate more adaptive operations as well as more adaptive passengers’ decisions. This scheme should be tractable, sufficiently fast and reliable to be used in real time applications. For...conference paper 2014

Barreto Cordero, W.J. (author)Flooding in urbanized areas has become a very important issue around the world. The level of service (or performance) of urban drainage systems (UDS) degrades in time for a number of reasons. In order to maintain an acceptable performance of UDS, early rehabilitation plans must be developed and implemented. In developing countries the situation...doctoral thesis 2012
