Autonomous Wireless Charging System for Robot Swarms: Charging Station Design

This project focuses on building a wireless charging station for the Lunar Zebro robots and building upon the existing functionalities by matching the interfacing voltage and current requirements for the wireless power transceiver.

Improving the Performance of Waste Handling Cranes by Optimisation-based Decision Rules

Waste-to-energy is the process of generating energy from municipal waste. The most conventional energy recovery method is incineration, which takes place at a waste-to-energy plant. The incoming waste is collected in a bunker, where an overhead crane stacks and mixes the material before feeding it to the furnaces. The more homogeneous the waste...

Micro-scale effects of stylolite orientation on the motion of tensile failure: A study analyzing strain fields of stylolite limestones using Particle Image Velocimetry

Many laboratory tests of samples where the rock fractures are based on<br/>meso-scale (cm) characterization of effective ‘intact’ strength parameters neglecting the microstructure effects. Understanding fracturing processes at<br/>micro-scale (mm) will require models with microstructure data. However,<br/>data is lacking on micro-scale.<br/...

An Elliptic Curve Cryptography Acceleration Core for OpenVPN on an FPGA Softcore

Elliptic Curve Cryptography (ECC) performance is a major performance bottleneck when serving many VPN clients from a single server on a low-frequency FPGA softcore CPU. Using an area-efficient Elliptic Curve Point (ECP) multiplication accelerator core on the same FGPA, a much higher amount of clients can be served using the same FPGA chip. Using...

Bottom-up manufacturing of nanocrystalline diamond micro structures and components

The exceptional material properties of bulk diamond like high stiffness, high thermal conductivity, wide optical transparency, chemical inertness and bio-compatibility make it the material of choice in many high-end applications. Most present-day diamond micro-devices are fabricated by costly and time-consuming top-down methods, such as focussed...

On The Cap Set Problem: upper bounds on maximal cardinalities of caps in dimensions seven to ten

This thesis concerns the cap set problem in affine geometry. The problem is illustrated by the card game SET and its geometrical interpretation in ternary affine space. The maximal cardinality of a cap is known for the dimension one to six. For the four lowest dimensions, a maximal cap is constructed and the optimality of its size proven. From...

Software Performance Engineering in Complex Distributed Systems

Performance is a make-or-break quality for software. When making changes it is essential to ensure no performance regression has occurred i.e. the program performs more slowly or consumes more resources than previous versions. Tribler is the result of ten years scientific research in complex distributed systems. Over the course of years Tribler...

Augmented Reality in a Virtual Reality Setup: Video transfer and processing

This thesis covers part of the development of the project "Augmented Reality in a Virtual Reality Setup". The covered part is about the communication between a Personal Computer (PC), and an FPGA (Field-Programmable Gate Array) and vice-versa. This communication is crucial for transfer of a camera stream from the FPGA to the PC and applying...

Design of a Hydraulic Prosthetic Hand: Adding an active thumb to the Delft Cylinder Hand

Body Powered Hand Prostheses provide the user with a replacement for a missing hand. Current body powered hand prostheses are inefficient and require large input forces for the control. Improvements are needed to provide amputees with adequate body powered hand prostheses. The Delft Cylinder Hand, a promising design for an underactuated...

Android Tor Tribler Tunneling (AT3): TI3800 Bachelorproject

Tribler is a decentralized peer-to-peer file sharing system. Recently the Tribler development team has introduced anonymous internet communication using a Tor-like protocol in their trial version. The goal of our bachelor project is to port this technology to Android devices. This is a challenging task because cross-compiling the necessary...

Making a Point

Urban and Architectural design for Zeeburgerpad, Amsterdam. Reconnecting this urban void with its surrounding urban network through physical, spatial and programmatic connections. The most strategic connection is architecturally elaborated in the form of an transferium with three residential towers.

Microscopic interaction behavior between individual pedestrians

Due to growing mobility in densely populated urban areas, public pedestrian walkways are becoming more and more crowded. Since space in these densely occupied areas is highly valued, the use of every square meter must be evaluated carefully. Microscopic pedestrian simulation models can provide such evaluation. However, fundamental knowledge on...

Hydrodynamic pressures on large lock structures

When a navigation lock, dam, or any other structure with water is subjected to an earthquake, one of the dynamic loads will be hydrodynamic pressure. This is the pressure exerted by the fluid on the structure as a result of the different behavior in motion of solid and fluid. To determine this pressure there are several available methods which...

Sphinx: Locating Malicious Nodes in CorporateDistributed Hash Tables

Nowadays structured overlay networks are used in controlled environments like company wide area networks. Even though these structured overlay networks are usually closed, there is still the risk that one or more nodes get compromised by attackers. When these networks provide business critical services, serious harm can be done by a compromised...
