Breakwaters can be divided into two maintypes: the classic (rubblemound) type breakwater and the vertical (caisson) type breakwater. In general it is assumed that vertical type breakwaters are more economic than classic type breakwaters, due to the quadratic increase of volume of material needed for the classic type breakwater as a function of...

The demand for energy is still increasing, together with the desire to create more durable solutions. Wind energy is currently one of the most promising ways to provide both. A shortage of suitable land sites was the main reason for considering the location of the wind farms offshore, which also offers higher wind speeds. A problem however is...

Advanced plans were made by the Dutch government to extend the port of Rotterdam by means of the construction of a land reclamation in the North Sea, the Maasvlakte 2. Because no safety standards exist for the Maasvlakte 2, it is useful to determine an optimal design from an economic point of view by cost-benefit analysis. The economic optimal...

The design of a marine propeller is characterized by its complexity rather then its shortcoming of knowledge how to asses its performance. There are several constraints to satisfy and all are in a different field. The three major considerations are strength, performance (efficiency) and cavitation behavior. There is not a perfect design...

This MSc thesis reports the results on optimizing the Al-Shaheen field performance using smart well technology. The field is currently being developed by Maersk Oil and Gas (MOG) offshore Qatar, using large-scale water injection on very long horizontal wells. The studied reservoir consists of a laterally uniform, tight matrix. However, undesired...

In current practice stope mines are designed using simple rules of thumb or using algorithms that do not find the true optimisation. Therefore a combinatorial optimisation algorithm was developed for optimising stope boundaries for sublevel stope mines. The profitability of a stope and the feasibility of a mine depends on the infrastructure that...

New developments in the gas market urge public and private concerns to gain deeper insight into how this market is functioning. The Energy Research Center of the Netherlands (ECN), as a leading research institute, has developed a deterministic model representing the European gas market called GASTALE. Based on this model, this research has been...

The performance of a feedforward controller depends on the accuracy of the internal model used for generating the control action. In this research we focus on the influence of parameter uncertainty on the performance of a feedforward controller. A simulation study is performed on a one and two D.O.F. planar robotic arm to improve the open-loop...

In recent years, space missions to asteroids have been a focus of research. This type of mission has introduced a new challenge in space mission analysis: target selection. Indeed, given the large number of small Solar System bodies and their various orbital and physical characteristics, selecting a specific target is a rather complex task. This...

Hardware acceleration using recon?gurable devices is a hot research item. To facilitate this acceleration technique, also called recon?gurable computing, tools are being developed that translate High-Level Languages into Hardware Description Languages. DWARV is such a tool developed at Delft University of Technology, translating C into VHDL. The...

In high-precision, high-speed machines, transient thermal stresses cause deformations that are difficult to compensate for on the short time-scale. To improve a structure’s (short-time) response to thermal loading the cooling layout can be modified, but this problem is not suitable for traditional optimising techniques. Thermal modes can be used...

The project would serve as a model in (architectural) academic circles as one that combines in-deterministic parameters such as culture, political and social; and deterministic parameters that affect spatial organization, such as the local environment, climate and built context. As an architectural/social experiment, it would serve as a model...

The objective of the study was to investigate the effects of coagulation and operational flux on the membrane performance of an inline coagulation/ultrafiltration process for water treatment in the lab. A two-phase optimisation approach was adopted in order to achieve stepwise performance improvement using raw water (taken from one of Singapore...

In emergency medical service (EMS) the use of optimisation models and Operations Research techniques is becoming more common. EMS providers incorporate facility location models and simulation software packages into decision support tools, allowing the extensive evaluation of 'what-if' scenarios. We give a literature survey of facility location...

This thesis investigates whether interval methods can be employed in the construction of a novel controller synthesis algorithm based on backward induction. Interval methods are methods employing interval arithmetic, which is an arithmetic defined on real-valued intervals rather than on real-valued numbers. In the controller synthesis algorithm...

The material properties of fibre reinforced polymer composites fundamentally differ from construction steel, and therefore a different approach is required in the design of structures composed of this material. Simple substitution of steel elements by composite counterparts will inevitably result in inefficient structures. When the material’s...

Since the development of the exponential sinusoid for low-thrust trajectory design by Petropoulos and Longuski [2004], more shape-based methods have emerged that ease up the work of a mission analyst. These methods are the ideal tool to generate a quick and almost complete overview of a large search space and are useful for producing first...

Decision Support Systems (DSSs) that are used nowadays by water managers often predict states that do not correspond with the observed states. This is caused by changing parameters in the real systems, while the parameters used in the current DSSs are kept at a fixed level or follow a temporal pattern that does not always represents reality....

In a previous study, the optimal re-entry trajectory of Hyperion-2 has been derived. The mission of the vehicle is to measure hypersonic boundary-layer transition, a phenomena in which the laminar boundary layer turns into a turbulent boundary layer. This is an important feature in hypersonic flow to investigate, as it introduces peak heating...
