de Jong, T.L. (author), van de Berg, N.J. (author), Tas, L. (author), Moelker, Adriaan (author), Dankelman, J. (author), van den Dobbelsteen, J.J. (author)Purpose: Accurate and precise needle placement is of utmost importance in interventional radiology. However, targeting can be challenging due to, eg, tissue motion and deformation. Steerable needles are a possible solution to overcome these challenges. The present work studied the clinical need for steerable needles. We aimed to answer three...journal article 2018

Salauddin, M (author), Broere, A. (author), van der Meer, J.W. (author), Verhagen, H.J. (author), Bijl, E (author)Single layer concrete armor systems are being widely used nowadays in the design of rubble mound breakwaters. Recently, a new concrete armor unit has been developed and applied as single layer armor system in the repair works of one damaged breakwater at Al Fujeirah, UAE. It has a symmetrical shape, in contrast to most other units. Modern...journal article 2017

Broxterman, Stefan (author)Topology optimization is a strong approach for generating optimal designs which cannot be obtained using conventional optimization methods. Improving structural characteristics by changing the internal topology of a design domain has been fascinating scientists and engineers for years. Topology optimization can be described as a distribution of...master thesis 2017

Hogervorst, T.A. (author)The memory-wall problem is a big challenge that classical Von Neumann-based computer systems face. This problem is caused by the increasing performance gap between the main memory and the central processing unit. The novel Computation-in-Memory (CiM) architecture can solve the memory wall problem by using emerging memristor technology to perform...master thesis 2017

Tonnaer, R. (author)The strict quality requirements for aerospace composite structures give rise to costly quality control procedures. In automated fibre placement (AFP) these procedures rely heavily on manualwork and inspection. This research aims at performing preventative non-destructive evaluation of composite laminate quality based on an online geometric...master thesis 2016

Kevelam, M.D.J. (author)In the offshore industry rock is used for different kind of applications, such as scour protection and pipeline protection. In deep water operations, but also increasingly in shallow water operations, use is made of the method by guiding the rock from the water surface to the seabed with a fallpipe. During a rock placement operation a current...master thesis 2016

Vlutters, M (author), van Asseldonk, EHF (author), van der Kooij, H. (author)In many simple walking models, foot placement dictates the center of pressure location and ground reaction force components, whereas humans can modulate these aspects after foot contact. Because of the differences, it is unclear to what extent predictions made by models are valid for human walking. Yet, both model simulations and human...journal article 2016

Salauddin, M. (author)In the design of rubble mound breakwaters, nowadays single layer systems using concrete armour units have become more common practice compared to conventional two layer systems. However, after the introduction of the accropode in eighties, a small number of single layer armour units have been developed over the years; for example core-loc, A...report 2015

Van der Spek, I.T. (author)In industrial environments robots are used for various tasks. At this moment it is not feasible for companies to deploy robots for productions with a limited batch size or for products with large variations. The use of robots for such environments can become feasible through a new generation of robots and software which can adapt quickly to new...master thesis 2014

Hassanabadi, M. (author)Oil production optimization is one of the main concerns of the reservoir management. In this regard, optimal location of wells can lead to a significant increase in the oil production. The purpose of this research is to investigate a new extension of the automatic well-placement optimization technique maximizing the net present value (NPV) of...report 2013

Khani, A. (author)Automated fibre placement (AFP) machines are able to place simultaneously several bundles of fibres, called tows, on a surface. Using AFP machines, it is also possible to manufacture composite laminates with fibres placed in curvilinear paths. The fibre orientations and stiffness properties of these laminates are spatially varied and hence they...doctoral thesis 2013

Nagelsmit, M.H. (author)Composites are notorious for their poor impact behaviour. Delaminations seriously decrease the compressive strength of the material after impact. Laminates made from woven fabric show in general more beneficial impact behaviour than laminates with unidirectional layers, but their manufacturing process is harder to automate. The new fibre...doctoral thesis 2013

Nanut, I. (author)Percutaneous procedures are minimally invasive medical procedures that use needles to locally operate on a target in a patient’s body. The precise placement of the needle in the body is a challenging task that can affect the quality and efficiency of these procedures. Needle insertion accuracy may be improved by robot-assisted control of...master thesis 2013

Holt, S. (author)The upstream oil and gas industry focuses increasingly on unconventional gas resources to maintain the level of its hydrocarbon reserves. To unlock the full potential of gas shale reservoirs, horizontal wells are drilled and active stimulation of the reservoirs, in the form of multi-stage hydraulic fracturing, is performed. This new technique...master thesis 2011

Van Campen, J.M.J.F. (author)Advancements in automated fibre-placement (AFP) technology make it possible to take laminate tailoring further than just stacking sequence optimisation; they enable the designer to vary the fibre orientation angle spatially within each ply. Spatial variation of fibre orientation angles results in a variable stiffness (VS) laminate. The work...doctoral thesis 2011
