Electric pulse fishing is a very promising and innovative solution instead of using tickler chains such as beam trawling, to enable the catch flat fish. Bottom-trawling activities on the marine ecosystem cause the scrape of the surface or dig into the seabed. The penetration of the gears produce the …

Het Sailing Innovation Centre is een dynamisch en innovatief bedrijf binnen de zeilsport wat de samenwerking tussen wetenschap, sport en bedrijfsleven stimuleert. Het centrum beschikt over een hangbank waarmee zeilers kunnen trainen. De hangbank bevat een forceplate en een hangband waarmee krachten gemeten …

Over the past decades, Inconel 718 and titanium 6Al4V have established their roles as prefered material in the gas turbine industry. Production of complex parts with these alloys using conventional production however is time consuming and expensive. With AM fabrication of metals developing fast, the …

In pre-treatment dose verification, low resolution detector systems are unable to identify shifts of individual leafs of high resolution multi leaf collimator (MLC) systems from detected changes in the dose deposition. The goal of this study was to introduce an alternative approach (the shutter technique) …

In this thesis the workings of a time-resolved setup are treated as well as the underlying physics. The setup is based on optical gating, which gives control over very short moments in time to let light pass through a gate. As this process is stable, light can be studied in very short and low intensities. …

Abstract A setup is designed and constructed to perform specular reectance spectroscopy on an enzymatic reaction, while simultaneously monitoring the heat produced by the reaction using a FLIR camera. The spectrum of ethanol was recorded using two MCT detectors and showed clear overlap with literature …

Raman spectroscopy is an optical technique that is based on the inelastic scattering of light. It is non-invasive, fast, objective and easy to use. These traits make it an ideal tool for use in medical diagnosis. Melanoma is the deadliest form of skin cancer. Currently, melanomas are visually diagnosed …

The objective of this study was to introduce a new iterative method to reconstruct multi leaf collimator (MLC) positions based on low resolution ionization detector array measurements and to evaluate its error detection performance. The iterative reconstruction method consists of a fluence model, a detector …

The lack of in-depth understanding of the seismic behavior and ductility of precast concrete structures makes it difficult to reach to ductility demand which could be exhibited during an earthquake. The limitations are mainly related to the beam-to-column connections as the main load transfer paths. …

Op verzoek van Jelle Scheurleer: Purpose: To investigate the accuracy of dose calculation on cone beam CT (CBCT) data sets after HU-RED calibration and validation in phantom studies and clinical patients. Material and methods: Calibration of HU-RED curves for kV-CBCT were generated for three clinical …
