Trying to choose the less bad route: Individual migratory behaviour of Atlantic salmon smolts (Salmo salar L.) approaching a bifurcation between a hydropower station and a navigation canal Instituut voor Natuur- en Bosonderzoek
Contrary to small- and medium-sized rivers, little attention has been paid to the downstream migration of Atlantic salmon smolts in large-sized rivers and the size-related impact of hydropower stations. From 2014 to 2016, we investigated the downstream migration of n = 72 acoustic-tagged smolts in the Meuse river at a bifurcation zone between a hydropower station equipped with three Kaplan turbines and a navigation canal. A hydrodynamic model ...
Stochastic User Equilibrium with Full Route Set in Dynamic Traffic Assignment KU Leuven
In current practice, there are two main concepts to handle the route set in an equilibrium route choice model. The first one is to maintain a fixed route set throughout the iterations for each OD pair. The second one is to determine the route set during the execution (every iteration or less), depending on the current congestion levels. They both have some problems. With a fixed route set, there is a change that an important route is not ...
Consistent iterative algorithm for stochastic dynamic traffic assignment with a stable route set KU Leuven
In stochastic (dynamic) traffic assignment (DTA), route choice (RC) formulationswith implicit route set require lessmemory than their explicit counterparts. To compute turn probabilities, however, a topological ordering of the nodes is needed, which negatively impacts the stability of convergence and consistency of equilibrium. This paper formulates a general framework for theRCmodule of the efficient stochastic DTA (ESDTA) without topological ...
Kinetic Monte Carlo Modeling of the Sulfinyl Precursor Route for Poly(p-phenylene vinylene) Synthesis Universiteit Hasselt Universiteit Gent
A kinetic Monte Carlo modeling study is presented for precursor polymer formation via the sulfinyl precursor route. The premonomer, 1-(chloromethyl)-4-[(n-octylsulfinyl)methyl]benzene, is subjected to a NatBuO induced 1,6-elimination in sBuOH yielding the actual p-quinodimethane monomer that leads, via a radical polymerization, to the precursor polymer. The kinetic Monte Carlo model is able to predict the experimental trends in yield, mass ...
Vitamin D: Dosing, levels, form, and route of administration: Does one approach fit all? KU Leuven
The 4th International Conference on Controversies in Vitamin D was held as a virtual meeting in September, 2020, gathering together leading international scientific and medical experts in vitamin D. Since vitamin D has a crucial role in skeletal and extra-skeletal systems, the aim of the Conference was to discuss improved management of vitamin D dosing, therapeutic levels and form or route of administration in the general population and in ...
Hydrogenation of Cyclic 1,3-Diones to Their 1,3-Diols Using Heterogeneous Catalysts: Toward a Facile, Robust, Scalable, and Potentially Bio-Based Route KU Leuven
Cyclopentane-1,3-diol (4b) has gained renewed attention as a potential building block for polymers and fuels because its synthesis from hemicellulose-derived 4-hydroxycyclopent-2-enone (3) was recently disclosed. However, cyclopentane1,3-dione (4), which is a constitutional isomer of 3, possesses a higher chemical stability and can therefore afford higher carbon mass balances and higher yields of 4b in the hydrogenation reaction under more ...
Which determinants influence modal choice? A review towards a better understanding of travel behaviour Vrije Universiteit Brussel
Abstract:
The aim of this review is to provide a better insight into the concept of modal choice so that it contributes to an improved knowledge on the different modal choice determinants and their interdependencies. This is vital to tackle our current mobility problems in a more efficient and sustainable way. Given the importance of modal choice decisions in our daily travel behaviour, this review on modal choice and its determinants ...
