Van der Ham, H.W.M. (author)Since the durability depends, among other things, on the quality of the concrete and presence of cracks, it is necessary to calculate the probability of cracking in hardening concrete as reliable as possible in case of durability predictions. In this thesis, it is investigated how the accuracy of stress prediction in hardening concrete can be...doctoral thesis 2011

Dey, A.K. (author)The Seismic Value Chain quantifies the cyclic interaction between seismic acquisition, imaging and reservoir characterization. Modern seismic innovation to address the global imbalance in hydrocarbon supply and demand requires such cyclic interaction of both feed-forward and feed-back processes. Currently, the seismic value chain paradigm is in...doctoral thesis 2011

Li, P. (author), Oosterling, J.A.J. (author), Hoogstrate, A.M. (author), Langen, H.H. (author), Munnig Schmidt, R.H. (author)In experiments of machining hardened tool steels (such as AISI H11, H13, and D2, up to 56 HRC) by commercial Ø 0.5 mm square endmills, it is observed that the tested micro endmills showed severe wear at an early stage of the process due to chipping off around cutting edge corners, resulting in unsatisfactory tool life and product appearance ...journal article 2011

Pel, A.J. (author)Regional evacuation planning is complex and timely. These planning studies can be assisted by a transportation model. In this thesis, we investigate the requirements for such a model, and develop, implement, and test a new model, called EVAQ, which meets these requirements. Two case studies show how EVAQ can be used to assess the success and...doctoral thesis 2011

Moradi Tehrani, A. (author)In this study we developed algorithms for fast frequency and time domain integral equation modelling for marine controlled-source electromagnetic (CSEM) applications. Solutions of integral equations for CSEM applications in a three-layered earth with an assumed reservoirs is examined using the conjugate gradient fast Fourier transformation (CG...doctoral thesis 2012

Chiong Meza, C.M. (author)Transitions are processes of change that have always occurred in society: for example, the production of goods changed from handcraft to machine-made. In recent years, these transitions attract more and more attention, mainly because societies now wish to actively bring about certain changes, such as the reduction of the use of fossil fuels –...doctoral thesis 2012

Shi, W. (author)Reducing fuel consumption from dredge vessels is always one of the priorities of the ship builder and the dredge contractor. In addition there is an increased awareness worldwide regarding exhaust emissions. CO2, NOx and SOx currently are or will in future be regulated strictly by international legislation and local authorities. Looking at a...doctoral thesis 2013

Van Wageningen-Kessels, F.L.M. (author)How to model and simulate traffic flow including different vehicles such as cars and trucks? This dissertation answers this question by analyzing existing models and simulation methods and by developing new ones. The new model (Fastlane) describes traffic as a continuum flow while accounting for different types of vehicles. It is reformulated in...doctoral thesis 2013

Kleptsova, O. (author)In this thesis a z?layer unstructured C-grid finite volume hydrostatic model is presented. An efficient and highly scalable implicit technique for the solution of the free surface equation is combined with an Eulerian approach for the advection of momentum. A consistent velocity reconstruc- tion procedure which not only satisfies the continuity...doctoral thesis 2013

(author)A long-lasting barrier protection at damaged sites of coated system can be achieved by means of an active response of the primer. This may be attained through the release of reactive liquids from dispersed containers, the increase of the local mobility of the polymeric network, or the expansion of (dispersed elements in) the primer [1]. Such...conference paper 2013

Galindo Nava, E.I. (author)This work aims to describe plastic deformation and microstructure evolution of metals at various scales in terms of dislocation behaviour. The theory is based on statistical thermodynamics, where the entropy is proposed to incorporate the possible paths for dislocation motion. Other than estimating the velocity gradients a dislocation may reach,...doctoral thesis 2013

Janulevicius, A. (author)Myxobacteria are social bacteria that are remarkable for their complex life cycle. In vegetative state, when nutrients are available, myxobacteria cooperatively swarm on a solid surface and feed. When exposed to starvation conditions, myxobacteria exhibit multicellular morphogenesis: 10^5-10^6 cells aggregate to form a fruiting body. Due to...doctoral thesis 2014

Rios Soltero, E.F. (author), Spitas, C. (author), Flipsen, S.F.J. (author), Savelberg, H.H.C.M. (author)Due to the complexity of joints and the difficulty to get accurate position measurements, most biomechanical analyses regarding cycling are based on some basic assumptions. For instance, a fixed distance is often set between the hip joint and the seat. Sometimes, this joint is considered to be coincident with the line of the seat-tube. Other...journal article 2014

Van Wageningen-Kessels, F.L.M. (author), Hoogendoorn, S.P. (author), Daamen, W. (author)Consistent definitions of important variables in pedestrian flow dynamics are proposed. They are based on the definition of similar variables for road traffic flow from the 1960's by Edie. The definitions are extended to include multi-class flows where pedestrians move in different directions or have different characteristics. The new...journal article 2014
