Observation thinning in data assimilation computations

open access: yesEURO Journal on Computational Optimization, 2015
We propose to use an observation-thinning method for the efficient numerical solution of large-scale incremental four- dimensional (4D-Var) data assimilation problems.

A Subgradient Method for Free Material Design [PDF]

open access: yes, 2016
A small improvement in the structure of the material could save the manufactory a lot of money. The free material design can be formulated as an optimization problem.

Complementarity-based nonlinear programming techniques for optimal mixing in gas networks

open access: yesEURO Journal on Computational Optimization, 2019
We consider nonlinear and nonsmooth mixing aspects in gas transport optimization problems. As mixed-integer reformulations of pooling-type mixing models already render small-size instances computationally intractable, we investigate the applicability of ...

Joint dynamic probabilistic constraints with projected linear decision rules [PDF]

open access: yes, 2016
We consider multistage stochastic linear optimization problems combining joint dynamic probabilistic constraints with hard constraints. We develop a method for projecting decision rules onto hard constraints of wait-and-see type.

An interior-point method for nonlinear optimization problems with locatable and separable nonsmoothness

open access: yesEURO Journal on Computational Optimization, 2015
Many real-world optimization models comprise nonconvex and nonsmooth functions leading to very hard classes of optimization models. In this article, a new interior-point method for the special, but practically relevant class of optimization problems with

The role of child language ability and parental mentalization in early child dysregulation

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 47, Issue 1, January 2026.
Abstract Dysregulation in early childhood is associated with increased vulnerability to psychopathology and poor psychosocial outcomes. While there is evidence that both child language ability and parental mentalization are associated with dysregulation in early childhood, there is little understanding of the relationships between these variables, and ...

Solving wind farm layout optimization with mixed integer programs and constraint programs

open access: yesEURO Journal on Computational Optimization, 2014
The wind farm layout optimization problem is concerned with the optimal location of turbines within a fixed geographical area to maximize profit under stochastic wind conditions. Previously, it has been modeled as a maximum diversity (or p-dispersion-sum)

A strategic approach for the ambulance covering of the province of Friesland [PDF]

open access: yes, 1998
In the summer of 1995 the University of Twente, commissioned by the Province of Friesland, carried out research into the consequences of alternative locations for ambulances.

Portfolio optimization with two coherent risk measures

open access: yes, 2020
We provide analytical results for a static portfolio optimization problem with two coherent risk measures. The use of two risk measures is motivated by joint decision-making for portfolio selection where the risk perception of the portfolio manager is of

Comparative efficacy of selenoureido carbonic anhydrase inhibitors and azole antifungal drugs against clinical isolates of Malassezia pachydermatis

open access: yesVeterinary Dermatology, Volume 36, Issue 3, Page 302-313, June 2025.
Background – Malassezia pachydermatis (MP) is implicated in severe dermatitis and otitis externa (OE) of companion animals and recently gained attention for its increasing resistance to azole compounds. For this reason, developing novel therapeutic strategies is of great interest. In a previous work, we used reference yeast isolates to evaluate several
