Vermeulen, F. (author)Selective Laser Melting (SLM) is an Additive Manufacturing (AM) technique that uses a laser to selectively melt metallic powder in a layer-wise manner, in order to produce functional metal components. It offers great freedom in design and facilitates fast iterations, with the potential of speeding up development phases throughout a wide range of...master thesis 2016

Babaei, S. (author)Cancer is a complex disease that results from alterations in genes that control the growth and division mechanisms of the cell. Identifying cancer-associated genes and pathways through which these genes influence cellular function is the key challenge in cancer re- search. This thesis proposes novel computational approaches that integrate data...doctoral thesis 2015

Lukovic, M. (author), Schlangen, E. (author), Savija, B. (author), Ye, G. (author), Copuroglu, O. (author)Simulation of mechanical behaviour of heterogeneous materials is only possible if the local properties of the components are known. In recent years nano-indentation is being applied on different levels to obtain local mechanical properties. The aim of this paper is to explore various ways to obtain these properties by combining nano-indentation...conference paper 2015

Verbree, E. (author), De Vries, M.E. (author), Gorte, B.G.H. (author), Oude Elberink, S. (author), Karimiou, G. (author)Water run-off modelling applied within urban areas requires an appropriate detailed surface model represented by a raster height grid. Accurate simulations at this scale level have to take into account small but important water barriers and flow channels given by the large-scale map definitions of buildings, street infrastructure, and other...conference paper 2013

Ofi?eru, I.D. (author), Bellucci, M. (author), Picioreanu, C. (author), Lavric, V. (author), Curtis, T.P. (author)A simple “first generation” multi-scale computational model of the formation of activated sludge flocs at micro-scale and reactor performance at macro-scale is proposed. The model couples mass balances for substrates and biomass at reactor scale with an individual-based approach for the floc morphology, shape and micro-colony development. Among...journal article 2013

Lark, R.J. (author), Al-Tabbaa, A. (author), Paine, K. (author)This paper presents a vision of a sustainable and resilient built environment that is comprised of materials and structures that continually monitor, regulate, adapt and repair themselves without the need for external intervention. In this way, these self?healing materials and intelligent structures will significantly enhance durability and...conference paper 2013

Qian, C. (author)In this research, extensive fatigue tests were performed on single glass fibres and composite coupons. Comparison of the test results shows that there is a significant difference between the fibre and composite fatigue behaviour. In order to clarify this difference, a multi-scale micro-mechanical model was developed. This model predicts fatigue...doctoral thesis 2013

Li, Y. (author)Scale is an important parameter of images. Different objects or image structures (e.g. edges and corners) can appear at different scales and each is meaningful only over a limited range of scales. Multi-scale analysis has been widely used in image processing and computer vision, serving as the basis for many high-level image analysis systems....doctoral thesis 2013

Mercatoris, B.C.N. (author), Massart, T.J. (author), Sluys, L.J. (author)This contribution discusses a coupled two-scale framework for hydro-mechanical problems in saturated heterogeneous porous geomaterials. The heterogeneous nature of such materials can lead to an anisotropy of the hydro-mechanical couplings and non-linear effects. Based on an assumed model of the mesostructure, the average macroscopic hydro...conference paper 2013

Karamnejad, A. (author), Nguyen, V.P. (author), Sluys, L.J. (author)A multi-scale numerical approach for modeling cracking in heterogeneous quasi-brittle materials under dynamic loading is presented. In the model, a discontinuous crack model is used at macro-scale to simulate fracture and a gradient-enhanced damage model has been used at meso-scale to simulate diffuse damage. The traction-separation law for the...conference paper 2013

(author)Matching of building polygons with different levels of detail is crucial in the maintenance and quality assessment of multi-representation databases. Two general problems need to be addressed in the matching process: (1) Which criteria are suitable? (2) How to effectively combine different criteria to make decisions? This paper mainly focuses on...conference paper 2012

Terwisscha van Scheltinga, A. (author), Myers, P.G. (author), Pietrzak, J.D. (author)A new mesh size field is presented that is specifically designed for efficient meshing of highly irregular oceanic domains: archipelagos. The new approach is based on the standard mesh size field that uses the proximity to the nearest coastline. Here, the proximities to the two nearest coastlines are used to calculate the distance between two...journal article 2012
