Zwaginga, J.J. (author), Lagemann, Benjamin (author), Erikstad, Stein Ove (author), Pruyn, J.F.J. (author)Shipowners need to prepare for low-emission fuel alternatives to meet the IMO 2050 goals. This is a complex problem due to conflicting objectives and a high degree of uncertainty. To help navigate this problem, this paper investigates how methods that take uncertainty into account, like robust optimization and stochastic optimization, could be...journal article 2024

Ojo, Adebayo (author), Collu, Maurizio (author), Coraddu, A. (author)The drive for the cost reduction of floating offshore wind turbine (FOWT) systems to the levels of fixed bottom foundation turbine systems can be achieved with creative design and analysis techniques of the platform with free-form curves to save numerical simulation time and minimize the mass of steel (cost of steel) required for design. This...journal article 2023

Revelo Obando, B.A. (author), Blacquière, G. (author)The ultimate goal in survey design is to obtain the acquisition parameters that enable acquiring the most affordable data that fulfills certain image quality requirements. We propose a method that allows optimization of the receiver geometry for a fixed source distribution. The former is parameterized with a receiver density function that...journal article 2023

Estrado, Erron (author), Turrin, M. (author), Eigenraam, P. (author)As technology advances, architects often employ innovative, non-standard shapes in their designs for the fast-growing number of high-rise buildings. Conversely, climate change is bringing about an increasing number of dangerous wind events causing damage to buildings and their surroundings. These factors further complicate the already...journal article 2022

(author), Morsch, Philipp (author), Heufer, Karl Alexander (author), Grohe, Martin (author), Mitsos, Alexander (author), Dahmen, Manuel (author)Fuels with high-knock resistance enable modern spark-ignition engines to achieve high efficiency and thus low CO<sub>2</sub> emissions. Identification of molecules with desired autoignition properties indicated by a high research octane number and a high octane sensitivity is therefore of great practical relevance and can be supported by...journal article 2022

Poplavskaya, K. (author)Balancing and redispatch are essential services for the security and stability of the electricity network. Balancing refers to continuously maintaining a balance between supply and demand through activating flexible resources. Redispatch refers to changing the dispatch of generators to remedy network congestion. The need for flexibility...doctoral thesis 2021

Pruyn, J.F.J. (author), van Grootheest, I.V. (author), Lafeber, Frans Hendrik (author), Scholtens, Marco (author)Stricter regulations for shipping on theemission to air and waterare introduced. To deal with this,a part of the Horizon2020 NAVAIS project is devoted to the identification of relevant regulations and the design of a tool to select the optimal combination of abatement options to achieve or go beyond the limits set by these regulations. Itis an...conference paper 2020

Çubukçuoglu, C. (author), Ekici, B. (author), Tasgetiren, M. Fatih (author), Sariyildiz, I.S. (author)Most of the architectural design problems are basically real-parameter optimization problems. So, any type of evolutionary and swarm algorithms can be used in this field. However, there is a little attention on using optimization methods within the computer aided design (CAD) programs. In this paper, we present Optimus, which is a new...journal article 2019

Bessa, M.A. (author), Głowacki, Piotr (author), Houlder, Michael (author)Designing future-proof materials goes beyond a quest for the best. The next generation of materials needs to be adaptive, multipurpose, and tunable. This is not possible by following the traditional experimentally guided trial-and-error process, as this limits the search for untapped regions of the solution space. Here, a computational data...journal article 2019

(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

Blacquière, G. (author), Nakayama, S. (author)Acquisition geometry design aims at finding the most affordable acquisition geometry that satisfies the objectives of the seismic survey. The parameters of an acquisition geometry can be specified in terms of the number of sources and detectors, their location, the blending parameters and the DSA (dispersed source array) parameters. In our...conference paper 2019

A string-based representation and crossover operator for evolutionary design of dynamical mechanismsKuppens, P.R. (author), Wolfslag, W.J. (author)Robots would perform better when their mechanical structure is specifically designed for their designated task, for instance by adding spring mechanisms. However, designing such mechanisms, which match the dynamics of the robot with the task, is hard and time consuming. To assist designers, a platform that automatically designs dynamical...journal article 2018

Cong, Z. (author)Due to the rapid growth of human population, and jobs being distributed unevenly in different locations, daily commuting is required more than ever, which in its turn is creating a huge socio-economic issue: traffic congestion. In order to prevent, or at least to alleviate this problem, trafficmanagement and control is urgently required. This...doctoral thesis 2015

Miranda, C. (author), Teixeira, A. (author), Huber, M. (author), Schweckendiek, T. (author)The traditional Dutch way to deal with piping failure in river dikes is the implementation of piping berms. The disadvantage of such a measure is the required inland space. Relief wells, on the other hand, require less or no inland space representing an attractive alternative solution. The aims of this paper are first, to show how reliability...conference paper 2015
