The impact of a B-to-B container transferium on the sojourn time of inland container vessels

Rear Wheel Steer Bikes: Unconventional stable bicycle

The design of the ordinary bicycle has barely changed since the end of the 19th century. Until then it evolved to a well ridable machine with no need for further drastic modifications. However, around 2011 it was shown that, just like an ordinary bicycle, strange appearing designs could also be stable. One of these designs was a bicycle that...

Development of scaling methods for broadband turbulent noise in internal flow devices by means of experiments and CFD

Broadband turbulent noise can lead to fluid-acoustic and fluid-structure interaction and ultimately to mechanical failure of pipe systems. In HVAC (Heating Ventilating and Air Conditioning) systems broadband turbulent noise can radiate outwards where it is a nuisance or even harmful to people. A fast and simple approach for investigating...

A Numerical trimvariation study for ships operating in off-design conditions

Fuel efficiency is an important factor for the shipping industry both regarding new build vessels and existing vessels. A method to reduce the fuel consumption of existing vessels operating in off design conditions is to trim a vessel in the most optimum trim condition. The current approach to determine the most efficient trim condition is to...

Needle deflection in tissue

Introduction: One of the factors that contribute to the total needle-targeting error in medical procedures is needle deflection, which can lead to e.g. hemorrhage, prolonged intervention time and decreased treatment efficiency. This deflection can be defined as the deviation of the needle from its suspected straight insertion path. In this study...

The design of a new protocol to acccurately estimate the passive and active components of the muscle system

For this research a new protocol was developed which acquires rich enough data in terms of position, velocity and accelerations such that all the pasive and active parameters of the agonist and antagonist muscle of the wrist in the newest and for this study expended and adapted neuromuscular model can be accurately estimated. Concluded was that...

Rigid-body Simulation using Gaming Engines: A Study on the Usability of Gaming Industry Software for Simulating Engineering Problems

Conceptual Process Design and Techno-Economical Assessment of H2/CO2 Separation Using FricDiff Technology

The technology of FricDiff, an abbreviation of Frictional Diffusion, can be used to separate gases by adding a third gas, a so-called sweep gas, to the system. It is based on the diffusion difference of the feed molecules in the sweep gas. FricDiff is a proven principle and works at lab scale. The aim of the research is to study the technical...

Fluid Force Identification: Verifying and Validating a Method to Predict Wear of a Control Rod in a Nuclear Power Plant

In this thesis a method to model and identify the force inducing a vibration on the control rods of a nuclear power plant is verified, but could not be validated. The aim of the method is to be able to predict wear in future nuclear power plant designs. This study is based on a study by Bodel [1], and reviews, adjusts and extents its contents....

Investigation of Nonlinearities in the Superposition of Ship Motions by 6DOF Forced Oscillations

Modelvorming voor foutendetectie en -diagnose: Model voor luchtverwarmer en hydraulisch systeem

Een foutendetectie en -diagnose systeem (FDD systeem) heeft als doel in een proces fouten waar te nemen en deze fouten te lokaliseren. Om fouten te kunnen detecteren en diagnosticeren maakt een FDD systeem gebruik van meetdata die door het gebouwbeheersysteem (GBS) worden vastgelegd. Afhankelijk van de manier waarop deze data wordt gebruikt...
