Wiersum, B.S. (author)
In rivieren en kanalen worden bodembeschermingen toegepast om te voorkomen dat stromingen ontoelaatbare ontgrondingen veroorzaken. Naast natuurlijke stromingen in de rivier veroorzaken scheepsgeïnduceerde waterbewegingen deze stromingen. Een bodembescherming be staat meestal uit een toplaag met daaronder een of meer filters. De toplaag moet...

In de kust- en waterbouw worden regelmatig geometrisch open filterconstructies toegepast. Er bestaat onduidelijkheid over het doordringen van de hydraulische be lasting in de filterlaag en de invloed daarvan op de erosie van de basislaag. Eerder onderzoek geeft het verband aan tussen de schuifspanning op de filterlaag en schuifspanning op de...

Filterconstructies worden toegepast onder de teen en armour layer van uit breuksteen opgebouwde golfbrekers. Daarnaast worden zij vaak, als onderdeel van een bodembescherming, aangebracht op de zeebodem veer de teen van de golfbreker. Filterconstructies hebben als doel erosie van het onderliggende basismateriaal te voorkomen. Geometrisch-dichte...

Filterconstructies hebben als doel erosie te voorkomen in bepaalde delen van waterbouwkundige kunstwerken. Ze zijn opgebouwd uit een basislaag en een of meer filterlagen. Er zijn verschillende soorten filterconstructies. Ze worden over het algemeen zo gemaakt dat er geen erosie zal optreden van basismateriaal. Het is echter efficienter om een...

Filterconstructies hebben als doel constructies te beschermen tegen uitspoeling van grond en beschadiging door wateroverdrukken. Een granulaire filterconstructie bestaat uit een ofmeer lagen van granulairfiltermateriaal, die het onderliggende, loskorrelige basismateriaal tegenhoudt, maar het water doorlaat. Meestal wordt het criterium gehanteerd...

Thesis study into an alternative design for breakwaters made of granular materials like sand and quarry stone. In this design, the breakwater is constructed of a sand core and a layer of large stones directly on top of it, without the traditional filter layers in-between. The single layer of stones serves as one open filter layer that has to...

In Suriname groundwater is mostly used for drinking water production. Depending on the ground layers from which groundwater is extracted, groundwater is characterized as aggressive water. The disadvantage of aggressive water is its ability to cause corrosion of metal pipelines and cement bound materials. In drinking water practice this water...

Network Security is a significant issue nowadays. The information flow is enormous and the attacks have been substantially evolved.Every single packet of the flow must be scanned in deep and checked with all known attack rules (Deep Packet Inspection) to determine whether it is malicious. However, the task of Deep Packet Inspection requires a...

Wavelet Packet based Multi-Carrier Modulation (WPMCM) offers an alternative to the well-established OFDM as an efficient multicarrier modulation technique. It has strong advantage of being generic transmission scheme whose actual characteristics can be widely customized to fulfill several requirements and constraints of advanced communication...

Terrestrial water storage (TWS) can be defined as the storage of water on and below the land surface, and includes snow, ice, surface water, soil moisture, and ground water. TWS is a key component of the terrestrial and global hydrological cycles, which have important control over the water, energy and biogeochemical fluxes, and plays a major...

One of the important functionalities of Dynamic Spectrum Access is spectrum estimation. Accuracy and speed of estimation are the key indicators to select the appropriate spectrum estimation technique. In this thesis work, the possibility of employing wavelet packet decomposition as a basis for a new spectrum estimation approach is investigated....

Electron microscopy makes it possible to magnify samples at almost atom level by using electron beams to scan the sample. These images could be improved in terms of noise and sharpness. In this research we looked into the possibilities to use post-processing filters for improving the quality of electron microscopic images.

In this thesis, a UWB pulse generator is designed to be implemented in IBM 0.13 um technology. The pulse generator has a high spectral efficiency. Using amplitude control, any mismatch, process variation or temperature variation can be compensated for to comply with the UWB FCC mask. The pulse has an approximate duration of 2ns. The current...

This work addresses the problem of indoor state estimation for autonomous flying vehicles with an optic flow approach. The paper discusses a sensor configuration using six optic flow sensors of the computer mouse type augmented by a three-axis accelerometer to estimate velocity, rotation, attitude and viewing distances. It is shown that the...

A cobble sea defence appears to be an easy constructible protection, with relatively low total costs of ownership. Flume tests show that sand under such single layered constructions is stable. However, it is not exactly known how the hydraulic loading of a breaking wave is reducing in the filter. Two datasets containing pressure measurements in...

For the Rijnmond area around Rotterdam, there is a model which simulates the concentration NOx. NOx forms the basis of smog and causes trouble for the eyes and lungs. In the thesis, the model simulation are connected to series of measurements. With this connection, the uncertainty of the simulation will be reduced. The method for this reduction...

Tributing to the GATE project by TNO, this application was designed to create an extra layer between the project and 3D modelling artists. New users are now able to place procedural content in their 3D worlds, without knowing much of the environment or programming. A general filter can be created to apply to the environment, without knowing...
