Electrostatic Dust Removal System for a Lunar Rover Solar Panel Assembly: Electronics Design

Lunar dust presents a serious problem for future lunar rovers. Due to the charged nature of this fine dust, it tends to stick to sensitive elements like solar panels. It is clear that a system needs to be implemented in order to remove lunar dust to keep the output power of the solar panel at a satisfactory level. This paper develops the proof...

StructuralComponents 8: Facilitating early structural integration in conceptual building design with a force flow design tool

The objective of this project is to devise and develop a design tool that lets the user explore different force flows during conceptual design, with the goal to inform different geometries, thereby realizing an integrated design process. Key characteristics that this tool must incorporate to be successful are defined as feedback (the ability to...

Wideband and Energy Efficient Digital Transmitter

The ever increasing demand for faster data rates combined with the need for higher levels of integration, while keeping the production and operation cost to a minimum leads to the requirement of an efficient high bandwidth digital transmitter architecture. With the shortcomings of both polar and cartesian architectures, a new architecture is...

The Maassilo: A Concrete Excavation

Everybody knows concrete.... the building material that ones meant the future. Imagine it’s most extreme forms. I’m thinking of Sovjet concrete sculptures! Brutalist Architecture! And then think about what it would take to break parts of these adement concrete structures down. That is what this project is all about. <br/>Welcome to ‘A Concrete...

Target localisation and tracking in a UWB radar network: UWB Indoor Person Tracking

For both security and analytics, much research has gone into person tracking already. As a result, many<br/>different state of the art technologies exist. However, in darkness or without a direct line of sight, much<br/>less technologies are capable of this. The choices become especially limited when the setup needs to<br/>be portable.<br/>A...

Ice Rink Protection Systems: Improve and Apply a Numerical Model to Gain Insight in the Safety of Ice Rink Protection Systems

Many falls occur in speed skating, most of which end up in protective padding that is placed along the ice rink. In this research project a testing method was established that can be used to test the influence of different padding parameters on the performance of the padding in relation to the skaters’ injury risks. An existing numerical model...

Applying streamlined LCA to assess the environmental impact of the hotel branch

The Master’s programme Industrial Ecology is jointly organised by Leiden University and Delft University of Technology.

Validation and Application of a Fully Nonlinear Numerical Wave Tank

The present thesis considers numerical computations of fully nonlinear fluid-structure interaction. The aim of the thesis is to establish a well validated fully nonlinear numerical wave tank for the simulations of complex fluid-structure interaction of moored floating offshore structures. The numerical computations are carried out using the...

Visual keyboard layout: The adoption of a symbolic innovation

I gave myself the challenge to design a keyboard layout that could possibly break the keyboard lock-in. By using the design strategy of applying innovation adoption theory, neurodesign and my personal experience of being a dyslexic I was able to design a: visually grouped, symbolic, dyslexic and low-literate friendly keyboard layout innovation....

Developing a dynamic framework for the selection of niche strategies to introduce new high-tech products

In many industries innovation is essential for companies to remain competitive in the market place. However, due to the embedded nature of technology, the commercialization of radically new high-take products is a complicated task to manage. Due to the presence of barriers to direct large-scale diffusion within the incumbent market situation,...

An Extensible Toolkit For Real-Time High-Performance Wideband Spectrum Sensing

This document describes the design process of a software toolkit to perform high-performance wideband spectrum sensing. A prominent application of this is Cognitive Radio, a technique that aims to make more efficient use of the available radio spectrum. An extensive theoretical analysis will be performed. Various non-uniform sampling techniques...

Minimaliseren restlading: "Volvox Terranova"

De sleephopperzuiger "Volvox Terranova" is eigendom van Van Oord ACZ en heeft een laadcapaciteit van 20.000 m3. Na het walpersen van de lading blijft een restlading over van ca. ---m3. Het doel van dit onderzoek is een voorstel tot aanpassing van de "Volvox Terranova" te presenteren om de restlading te minimaliseren, zonder de leegzuigproductie...
