Dijkstra, J.T. (author)Worldwide, aquatic vegetation is important for the physical and ecological condition of coastal areas. Unfortunately, this vegetation (e.g. seagrasses) is also under pressure due to human activities. Protection and restoration are cumbersome, particularly because the complex relations between vegetation and its environment are not yet well...conference paper 2008

Dijkstra, J.T. (author)By changing flow patterns and sediment transport, aquatic vegetation can affect the development of estuarine bed topography. Besides, since the sediment transport also determines the amount of light available for photosynthetic growth, the presence of vegetation can also affect its own development. This selfsupporting interaction should be taken...conference paper 2007

Jansens, P.J. (author), Dijkstra, F. (author)The invention relates to a control system for a processing installation or production plant or the like, pro vided with at least one control loop, comprising a sensor, a controller and an actuator, the sensor being designed for measuring a parameter of the processing installation or the production plant that is to be controlled, and the actuator...patent 2007

Dijkstra, W.O. (author)In the thesis two different models of solidification of aluminum alloys are presented and analyzed. The first 1--D solidification model is derived from the conservation of solute, heat and mass. With numerical experiments it is shown that simulations with the Finite Difference discretization must adhere a relation similar to the Courant...doctoral thesis 2007

(author)This paper explores new methods to visualize and fuse multi-2D bioluminescence imaging (BLI) data with structural imaging modalities such as micro CT and MR. A geometric, back-projection-based 3D reconstruction for superficial lesions from multi-2D BLI data is presented, enabling a coarse estimate of the 3D source envelopes from the multi-2D BLI...conference paper 2007

Dijkstra, J. (author), Broere, W. (author), van Tol, A.F. (author)This paper presents the results of model pile penetration in a photoelastic material. The soil in this test is represented by an assembly of photoelastically sensitive glass particles. This allows for the determination of stresses in the assembly by the photoelastic method. Displacements around the pile are measured using digital image...conference paper 2006

Dijkstra, J.T. (author), Uittenbogaard, R.E. (author), Stive, M.J.F. (author)In many areas around the world, there is a large interest in the protection and restoration of aquatic vegetation, like eelgrass (Zostera marina), but little is known about the interaction of such vegetation with its environment. To improve this knowledge, a model has been developed that simulates this interaction between highly flexible...conference paper 2006

Dijkstra, J. (author)When in-situ tests are performed to determine the ultimate capacity of a pile after the installation, quite a lot of types of tests are available. The following tests are generally used, in order from most used method to least used method: the static testing method, dynamic testing methods, pseudostatic and statnamic testing methods. During a...report 2004

Dijkstra, B.G. (author)In the past Iterative Learning Control has been shown to be a method that can easily achieve extremely high performance with very limited effort from the user. Unfortunately an Iterative Learning Controller (ILC) exhibits some side effects such as amplification of system noise and control activity when the system should be at rest. This had led...doctoral thesis 2004

Dijkstra, J.T. (author), Schoor, M.M. (author)The 'Room for the River' strategy for Dutch river management asks for more information about morphodynamics and vegetation succession in natural rivers. In order to obtain such information, the Lower Volga River in Russia is chosen as a natural reference river for the Dutch Waal River. Objective of the project Morphodynamics Lower and Waal is to...report 2002

Van der Vaart, P.C.F. (author), Schuttelaars, H.M. (author), Calvete, D. (author), Dijkstra, H.A. (author)The wind-driven ocean circulation at midlatitudes is susceptible to several types of instabilities. One of the simplest models of these flows is the quasigeostrophic barotropic potential vorticity equation in an idealized ocean basin. In this model, the route to complex spatio/temporal flows is through successive bifurcations. The aim of this...journal article 2002
