Euler-Lagrange Simulation of Glycolytic Oscillations using the Lattice Boltzmann Method

The traditional Eulerian view of biomass in bioprocess modelling results in issues when modelling large-scale bioreactors in which heterogeneous conditions are common. As the field increasingly moves from “scale-up” to “scale-down” philosophy, in which such heterogeneities are included from the start of process design, accurate modelling of the...

Long-term Dynamics of Astrophysical Disks

context: The long-term evolution of a self-gravitating astrophysical disk can be modeled using secular perturbation theory. Recently, Batygin published a paper where he claims that such a disk with a special density can be described by a Schrödinger equation by using this method. aims: In this thesis, we will study the secular perturbation...

Het rendement van verschillende ontwerpen van de trebuchet bij het afschieten van een voorwerp

In dit project worden vier vereenvoudigingen van de trebuchet onderzocht. Er wordt gekeken naar het rendement met betrekking tot de energie overdracht van het zware tegengewicht op het afgeschoten voorwerp. De invloed van het toevoegen van extra armen en wielen wordt onderzocht. Bij meer energie overdracht kan het voorwerp verder weg geschoten...

Derivative Computation using an Adjoint-Based Goal-Oriented Iterative Multiscale Lagrangian Framework: Application to Reservoir Simulation

Even though negative effects on the use of crude oil have surfaced over the past years, our energy matrix still largely relies on this energy source. The production of oil, therefore, plays an important role in our society. Unfortunately, the process of oil production is highly uncertain. There are uncertainties associated on the production...

Combinations of Low Energy Trajectories for a Lunar L2 mission

Measurements in the frequency range below 30 MHz, key to a better understanding of the origins of our universe, are one of the last unexplored areas of radio astronomy. Low frequency measurements suffer greatly from disturbance from man-made signals. Therefore, satellite missions are proposed which use the Moon as a shield from these...

Synchronization of Uncertain Heterogeneous Agents: An Adaptive Virtual Model Reference Approach

Synchronization of Multi-Agent Systems (MASs) has the potential to benefit many technological<br/>areas such as formation control for unmanned vehicles, cooperative adaptive<br/>cruise control, and spacecraft attitude control. Information plays a crucial role in MASs:<br/>in centralized approaches, a central node utilizes global information to...

Force Estimation for Offshore Heavy Lifting Equipment

One of the phases of the installation of Offshore Wind Turbines is the installation of the foundation for the turbine. Herein, a monopile is one of the most frequently used foundation-types. This monopile is a high steel cylinder, over 60 meters high, which supports the wind turbine to the seabed. Currently, monopiles are lifted with large boom...

Analysis of the Sun-Earth Lagrangian environment for the New Worlds Observer (NWO)

Exoplanets have been detected for more than 15 years. In the vast majority of instances, this has been accomplished through indirect observation. Such methods include among others the observation of radial velocity, transit photometry, and timing variations. These techniques allow for the vast majority of exoplanet detections up to date. An...

A Substructuring Method to Apply Topology Optimization to System-Component Problems

Since its introduction, Topology Optimization (TO) has been applied to a broad range of design cases. TO is a material distribution method which finds the optimal material lay-out for a given design space while upholding given constraints and boundary conditions. This has made the method popular in structural mechanics where it is used to find...

Topology optimization of 3D linkages with application to morphing winglets

Topology optimization is the process of optimizing both the material layout and the connectivity inside a design domain. The first paper on topology optimization dates back to 1904, when the Australian inventor Michell derived optimality criteria for minimum weight truss structures. In 1988 Bendsøe and Kikuchi published the pioneering paper ...

Optimal Translunar Lagrange Point Orbits for OLFAR

Investigation of the feasibility of using translunar Lagrange point orbits for low-frequency radio wave astronomy, in particular for Orbiting Low-Frequency Antennas fro Radio astronomy (OLFAR). Furthermore suggesting swarm and orbit configurations that lead to the best possible results.

Optimal Thrust Allocation Methods for Dynamic Positioning of Ships

The first Dynamic Positioning (DP) systems emerged in the 1960's from the need for deep water drilling by the offshore oil and gas industry, as conventional mooring systems, like a jack-up barge or an anchored rig, can only be used in shallow waters. GustoMSC has been developing DP drill ships since the early 1970's and it is still one of their...
