All roads lead to ROMA: Design and evaluation of a Robust Online Map-generation Algorithm based on position traces

Keeping maps up to date is quite costly because road geometry changes over time and mapping by professional surveyors is an expensive operation. With the presence of GPS sensors on mobile phones and in most cars today it becomes possible to measure the location of roads with many measurements from sensors of lower accuracy. In this thesis we...

Fault-Tolerant On-Board Computer Software for the Delfi-n3Xt Nanosatellite

Fault-tolerant On-Board Computer (OBC) software for the Delfi-n3Xt nanosatellite is needed in order to minimize the risk of failures that may occur while the satellite is operating in space. Failures may be OBC specific, but failures that affect the state of the entire satellite and influence the health of the data bus may occur as well. Some...

Finding faulty components in a dynamic distributed system at runtime

This document describes the research performed on fault isolation in dynamic distributed systems at runtime. An existing Spectrum-based Multiple Fault Localization approach is used as the basis for fault isolation, but is adapted and optimized so it can be used for online diagnosis. The result is an algorithm, coined AIMBACH, which finds the...

Run-time Reconfiguration in Wireless Sensor Networks

A wireless sensor network (WSN) consists of multiple small and simple computers (nodes), whose performance is tightly linked to its unpredictable deployment environment. It is nearly impossible to design a WSN that performs well in every scenario; instead they are developed for a specific context, with performance rapidly decreasing when...

Simulating Interaction Between Tracked Real-World Objects and User-Controlled Virtual Objects

In recent years, interest in correspondence between virtual environments and realworld events has grown considerably. We investigate different methods of integrating position and orientation data of moving real-world objects and individuals into a virtual environment, and of simulating their interaction with virtual objects and individuals. This...

Hardwarekeuze voor het El Condor Soundsystem: Aanbevelingsrapport voor optimale hardware

Professionele muzikanten gaan naar een opnamestudio als ze een album willen opnemen van hoge geluidskwaliteit. Voor de beginnende muzikant zijn deze studio’s echter niet te betalen, aangezien een opname minstens €1500 kost. Het aanschaffen van eigen opnameapparatuur is nog vele malen duurder. In die hoge prijs gaat het El Condor Soundsystem...

Logic gene network design: A CAD tool based on modularity and standardization

Motivation: Synthetic biology aims at building biological systems for useful purposes. Relatively simple gene networks have been engineered, but the design process is limited. Many papers advocate the use of engineering concepts like standardization and modular design to simplify the design process and enable the design of more complex systems....

A Complete Peer-to-Peer Widget System

Nowadays, the World Wide Web is becoming more and more an interactive and social platform than just a means to find information. This is called the Web 2.0. Quite new in the World Wide Web are widgets; small applications that use a little area of a website and displays something specific, often making use of a Web 2.0 application to get its...

Digital Review: Final Project Report, Final report on the project of developing the Digital Review Application

SKION is a foundation that facilitates research of children with cancer. The research consists of investigating slides and other material gotten from the treating hospitals at SKION. The results of these investigations are saved into a database, while other information gathered by SKION through forms is stored in another database. Four times a...

Verkenningsoperaties in complexe objecten

De vraag waarop antwoord wordt gegeven in dit verslag is: "Hoe kan door middel van een intelligent informatiesysteem een goed beeld van de situatie, tijdens een BHV-inzet, gegeven worden waardoor de BHV efficier kan opereren?". Dit project biedt een mogelijke oplossing voor deze vraag in de vorm van een softwaresysteem. Het ontwikkelde systeem...

Volta: Research and Showcase

Developing software as a service is a new trend in the IT industry. Volta is a new technology that targets simplifying this type of software. It offers developers a toolkit that enables Web development in any .NET language. This is done by recompiling the CIL code to JavaScript for the client tier (browser) and a .NET application for the Web...

TOPdesk Bachelorproject - Veel modules

Wij hebben ons bachelorproject uitgevoerd bij software- en consultancy bedrijf TOPdesk. Zij hadden ons een interessante opdracht te bieden waarmee wij 8 april 2008 begonnen zijn. De opdracht hield in dat er een systeem gemaakt moest worden waarmee het toevoegen van softwaremodules (Eclipse-projecten) aan de Eclipse workspace vereenvoudigd wordt,...

Performance analysis of ATM buffers with prioritized actual traffic

The awareness that long-range dependence (or self-similarity) is present in data traffic and will have its effect on important traffic management issues is growing. The results of performance analysis and traffic engineering considerations drastically change when based on actual traffic instead of non-realistic Markovian models. In this paper,...

Voorwaarde voor correctie van de reflectiefout, bij satellietnavigatie in een stedelijke omgeving

In dit verslag wordt na enkele inleidende hoofdstukken, in het kort de correctiemethode voor fouten die worden veroorzaakt door signaalreflecties, beschreven. De voorwaarde om de correctiemethode te mogen toepassen is dat de acht aannames, voorafgaande aan de afleiding van de correctiemethodeformules, gerechtvaardigd zijn, en dat aan een tweetal...
