Architecting High Performance Multi-tier Enterprise Information Systems

This master thesis presents an empirical system architecting process, which addresses the system performance of multi-tier information systems in an enterprise environment. The process is demonstrated by a real practical architecting project as a case study. Such an architecting process begins from performance requirement analysis and ends with...

Lattice Tower Design of Offshore Wind Turbine Support Structures

Optimal design of support structure including foundation and turbine tower is among the most critical challenges for offshore wind turbine. With development of offshore wind industry heading for deeper ocean areas, new support structural concept such as a full lattice tower could be proven to be more advantageous than others when consideration...

Development and Characterization of an Endoscopic TOF PET System

The endoscopic time-of-flight (TOF) positron emission tomography (PET) concept has many advantages compared with the traditional PET system. It improves the image quality by delivering higher spatial resolution and enhancing the signal-to-noise ratio. Implementing the endoscopic TOF PET system in an ultrasonic probe requires an ultra...

Novel digital controller for boost PFC

LED lighting, as the fourth-generation lighting technology, is developing rapidly over the past years due to its high energy efficiency, longer life span and sustainability compared to incandescent light bulbs and CFLs. Today’s stand-alone LED drivers for professional lighting systems contain two cascaded power converters: an input and an output...

Exploring Human Activity Patterns Across Cities through Social Media Data

Cities are complex systems, a particular dimension largely contributing to the complexity of cities is detected in the multiplicity of the behaviour of people who inhabit. In the urban context, these behaviours can be inferred from human activities. Understanding the distinctions of these activities between cities is crucial. Previous works...

Design of a commercial port in Nador West, Morocco

Design of a port in Morocco, as part of the design workshop 2017 in Caen, France. <br/>This report includes a design from the new Nador West Med Port near Nador, Morocco. Given requirements are an entrance to the northeast and minimal dredging works to be conducted. A layout of the harbour is made for wave directions during storm from the...

Superhuman Sports

Video games have become increasingly more popular, but few focus on physical activity. VRabl, a multiplayer augmented reality sports game, stimulates players to be physically active, while providing similar aspects as video games. It is based on the well-known and popular game dodgeball to reach out to a large possible player community and have...

Outlier Detection for Pedestrian Movement

Fast development of tracking devices has made trajectory outlier detection(TOD) possible and meaningful. Given a set of trajectories T, a TOD algorithm outputs a subset of T, of which trajectories are different from mostof the other trajectories in some aspect(s). These trajectories, namely outliers, can indicate important or interesting...

Analysis and Design of a Ring-Oscillator-Based Fractional-N Injection-Locked Digital PLL for IoT Applications

Frequency translation is required in any modern wireless communication systems.<br/>This is in large part due to the fact that the modulated signal is easy to<br/>transmit in radio frequency in the form of an electromagnetic wave, and the demodulated signal is easy to process in the baseband frequency by a powerful digital processor. Frequency...

Coastal dune behavior and the role of sediment supply in the aeolian system

This thesis explores the nature of coastal dune behavior and the role of sediment supply in the aeolian system. The first part of the thesis conducts a data analysis based on the Dutch JARKUS dataset, which provides yearly measured profiles along the Dutch coast. A series of parameters derived from the profile measurements have been used to...

IPS as a tool for designing to improve the care for people with dementia: designing a new system for nursing home

This project aims to improving the care service for people with dementia who exhibits BPSD (Behavioral and Psychological Symptoms of Dementia) by providing the relevant stakeholders data insights, and meanwhile improving these people’s working efficiency.

Contextual Personalized Re-Ranking of Music Recommendations through Audio Features Based User Preference Models

With advancements in Internet and technology, it has become increasingly easy for people to enjoy music. Users are able to access millions of songs through music streaming services like Spotify, Pandora, and Deezer. Access to such large catalogs created a need for relevant song recommendations. Music recommender systems assist users in finding...

Meet Van Gogh in the City: Designing an Interactive Art Experience with Mixed Reality

The project aims at designing an engaging art experience outside the Van Gogh Museum (VGM) for young people. The experience should achieve the design goal of triggering young people’s interest in Van Gogh and his art through experiencing the connections between his personal stories and his painting style and technique in a mixed-reality...

Dual-polarization multi-frequency radar data processing for moving target detection

This project develops and tests algorithms for joint signal processing of data from two radars located on the rooftop of EWI (PARSAX and MESEWI). The particular tasks consist of automatic alignment of radar data in space (2D map) and time by observing moving targets of opportunity in the high-resolution mode. After the data alignment procedure,...
