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 …

Coupling beams between shear walls are one of the key elements for energy dissipation in tall buildings. A representative mathematical model of coupling beam should represent flexure, shear and interface slip/extension mechanisms simultaneously. This goal can be achieved by using either detailed finite …

Barges are used in order to transport all types of offshore structures and equipment. Structures which are transported are becoming larger and heavier. Therefore, there is need for barges that can handle these structures. This research will explore the possibilities to increase barge capacity by adding …

Finite element analysis on large structures in the mining industry is mainly set up with beamelements. During the modelling of the structures a couple of assumptions are made to ensure that the structure is not too complex. The connections between the beams are usually released in a couple of direction …

Achtergrond: In het Radboudumc wordt een stereotactische (SBRT) longbestraling uitgevoerd bij patiënten met een inoperabel, niet kleincellig longcarcinoom (NSCLC) stadium I – II. Voorafgaand aan de bestraling wordt een positieverificatie middels een Cone Beam CT (CBCT) uitgevoerd. Hierbij wordt een onderscheid …

A Quad Focus GridPix Gaseous Tracking Detector is under construction, to allow calibration and test beam measurements to validate the working principles of the (quad) GridPix detectors while using a focused electric field. The development is well on its way: both measurements should be able to be conducted …

PURPOSE: To determine the impact of late radiation-induced toxicity on health-related quality of life (HRQoL) among patients with prostate cancer. PATIENTS AND METHODS: The study sample was composed of 227 patients, treated with external beam radiotherapy. Common Terminology Criteria for Adverse Events …

The effect of an elevated sample temperature on the growth rate of carbon in the holes of a Multiple Aperture Array (MAA) has been examined. The loss of transmitted electrons through the MAA was measured by taking pictures with a camera of an Yttrium Aluminum Garnet (YAG) scintillation crystal. The growth …

For the simulation of a flexible helicopter rotor system the Euler equations for a rotating and translating beam structure are derived using the Finite Element technique. Using the displacements and velocities of a beam element which has an airfoil shaped cross section the aerodynamic forces and moments …
