A comparison of mathematical models for wave propagation in harbours

A wave entering a harbor will be diffracted and reflected, depending on the shape and the construction of breakwaters, quays and other objects in the harbor. The incoming wave can increase or decrease in height and a resonance can occur. This affects the manouvering of ships and the movement of moored ships, which influences the loading and...

The Road to Increasing Data Capacity in D2-HDMAC

After showing that D2-HDMAC would benefit from an increase in the data capacity, a technique for doubling the data capacity in D2-HDMAC has been developed. The influence of distortions and disturbances on the bit error rate of the original digital signal in D2- HDMAC has been investigated for comparison with the increased data rate signal.

Increasing PAL/VBI transmission capacity using multi-level coding and source compression

After explaining the need for a higher transmission capacity in the PAL/VBI, the current Teletext system is analysed. Two methods which increase the current VBI transmission capacity are presented, namely multi-level coding and source compression. The two methods can be implemented independently. Quaternary unipolar coding is analysed both...

Sound Reflections in an audio-based game for visually impaired children

In this thesis a model for sound reflections designed which is to be used in an audio-based game for visually impaired people is described. This project is a part of a three-group bachelor graduation project of six peoplein total. The three groups combined create a working game for visually impaired children, meant to be used to train the user’s...

Integrating gloss scan to the 3D fine art scanner

The gloss-capturing prototype was a first step towards the reproduction of the gloss levels in different parts of the painting and the basic principles were verified with this system. However, it was not yet an integrated system with the 3D fine art scanner. For this thesis the different components of the gloss scanner have been analyzed and...

A multi-surface reflected irradiance model for pyranometer corrections and PV yield calculations in complex urban geometries

The need for research of PV system performance in urban areas is increasing as more and more PV systems are installed each year. To facilitate this research, a PV monitoring station is constructed on the campus of the TU Delft in a complex urban geometry. Unfortunately, the diffuse horizontal irradiance (DHI) measurements that are measured using...

How Smart Objects Can Support Reflections on Health Behavior Change

It is difficult for people to find strategies that fit their needs for changing behaviors. This project investigates how individuals can be supported to reflect on their health behaviors through the use of technology. Through various research and design methods, the project provides a comprehensive overview of the literature on reflections, how...
