De Boer, E. (author)
The purpose of the research as described in this Doctor’s thesis is twofold. Firstly it is to define in how far Dutch facilities for primary and secondary education were subjected to spatial concentration during recent decades. Secondly it is intended to assess what this concentration implied for the development of the minimum necessary travel...

Understanding the interactions between the ecosystem and the morphology of river floodplains, i.e. floodplain biogeomorphology, is becoming increasingly important in view of modern river management and climate change. There is a need for predictive models for the natural response of river floodplains to hydraulic measures and river...

Over the last decades the reliability, availability and safety of ships has become increasingly important. The cost and safety risks of ships have increased with the size, and the complexity has led to extensive automation. Many parameters, variables and alarms are available simultaneously for evaluation, but the small crew has many tasks they...

This thesis presents new developments in the area of target identification with ground penetrating radar (GPR) intended for the identification of plastic and metal cased antipersonnel (AP) landmines from a single measured GPR return signal, called A-scan. The target identification is formulated as a deconvolution problem. As such, the measured...

Simulation fidelity is an intrinsic element of any simulation system, one that all its developers and users have to deal with one way or the other. It is commonly recognized by the modeling and simulation community that simulation fidelity is an essential vehicle in properly assessing the validity and credibility of simulation results....

Laminar separation bubbles may occur in a wide range of engineering applications such as turbomachinery flows, wind turbines, hydrofoils etc. Much attention has been given to their effect on the flow over airfoils because of the importance for an accurate prediction of lift, drag and heat transfer. In the aeronautical world, laminar separation...

Future high luminosity spallation neutron sources put strenuous demands on detector performance. This research has focused on applying the Gas Electron Multiplier (GEM) to meet most criteria, most notably mm spatial resolution, 1 MHz local countrate (per pixel) and 70% efficiency for 0.18 nm neutrons. The choice for this detector type was made...

Recent is een techniek ontstaan voor de aanpak van gecombineerde automatische analyse en ontwerp van een- of meerdimensionale elastische systemen in een omgeving van meervoudig parallel rekenen. De aanpak is gebaseerd op het paradigma van âcellular automata (CA)â. De implementatie van deze techniek voor het ontwerpen van constructies is in...

Neutron activation analysis is a powerful technique for the determination of trace-element concentrations. Since both neutrons that are used for activation and gamma rays that are detected have a high penetrating power, the technique can be applied for relatively large samples (up to 13 L), as demonstrated by Overwater. This technique resulted...

During the last decades many different seismic inversion algorithms have been developed. Since the problem to be solved is non-linear and does not have a unique solution, every method makes use of its own approximations and assumptions. As a step towards a new approach to the inversion of seismic data we have designed and partly implemented a...

The gas-lift technique uses gas injection in vertical oil wells to decrease the gravitational pressure drop. The decreased pressure in the production pipe results in an increase of the pressure drop from the reservoir to the oil well and enhances the oil production. In this thesis we investigated the influence of the bubble size and initial...

Many national governments throughout the world are involved in developing spatial data infrastructures (SDI) to facilitate the availability of information in such a way that the needs of the agencies, organization, citizens, commerce, and society in general are met. This book covers some of the most prevalent policy issues evolving around...

This thesis presents a broad range of work done in the field of Wireless Local Area Networks (WLANs). It proposes several novel schemes which performance are analyzed. The thesis first proposes an Automatic Repeat reQuest (ARQ) scheme named as Selective Repeat / Multi-Copy (SR/MC). The purpose of the proposed SR/MC ARQ scheme is to transmit...

Most of our knowledge of flow in porous media is obtained at the pore and the macro scale. For reservoir scale modelling it is not practical to model the flow at these fine scales. Considering the usual objectives (e.g. large scale flow pattern and production forecast) it is undesirable to have to gather the tremendous amount of fine scale data...

Each year over one billion pounds of acrylic-based polymeric products are produced world wide. Such products include windows in aircraft, lenses in eyeglasses and CD players, coatings on parquet flooring and various architectural structures such as skylights and domes. Often these products are made by injecting monomer or monomer solutions into...

Air Traffic Control (ATC) centers aim at ensuring safety of aircrafts cruising in their area. The information required to face this mission includes the data provided by primary and Secondary Surveillance Radar (SSR). The first one indicates the presence of an aircraft, whereas the second gives information on its identity and altitude. All...
