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...

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...

This paper presents the application of the open source non-hydrostatic wave-flow model SWASH to propagation of irregular waves in a barred surf zone, and the model results are discussed by comparing against an extensive laboratory data set. This study focus not only on wave transformation in the surf zone, but also on the numerical prediction of...

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...

Research in support of indoor mapping and modelling (IMM) has been active for over thirty years. This research has come in the form of As-Built surveys, Data structuring, Visualisation techniques, Navigation models and so forth. Much of this research is founded on advancements in photogrammetry, computer vision and image analysis, computer...

This research focusses on the use of consistent scenarios to help ship owners, banks and other parties with an interest the maritime business get a better grip on the future. Three levels of detail can be distinguished for the maritime industry. The macroeconomic level is the highest and focusses on the behaviour of countries and the trade...

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,...

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...

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...

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...

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...

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 –...

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...

GIS integrated 3D modelling is crucial for the city planning and design processes because urban modelling is a tool used in virtual environments, and provides convenience to work. Although, the creation and display of 3D city models for large regions is difficult it is vital for planning and designing safer cities, as well as public places....

Impact of development is a major issue of global environment change. The modelling and projecting of development are essential to the assessment of consequent environmental impacts. Thus, this research was conducted to develop a customised modelling system that integrates the strength of GIS in supporting planning decision making process via...

This article aims to compare the geo-graphic (spatial) objects in 2D (planar objects) proposed by CON.G.O.O. and ISO standards, and the ability of a number of GIS software to handle them. The results achieved so far showed that the actual technical possibilities are not always sufficient to support the complex spatial objects proposed by CON.G.O.O.
