Assessment of Emotion States During e-Learning

In recent years many systems for distance learning have been developed. Even though students have access to learning material any time and any place, current tools for e-learning still have their limitations. The main shortcoming, compared to real life learning is the limited opportunity for human like interaction between student, teacher and...

E-learning in virtual communities

In recent years many systems for distance learning have been developed. Even though students have access to learning material any time and any place, current tools for e-learning still have their limitations. The main shortcoming, compared to real life learning is the limited opportunity for human like interaction between student, teacher and...

An automated text-based synthetic face with emotions for web lectures

Web lectures have many positive aspects, e.g. they enable learners to easily control the learning experiences). To develop high-quality online learning materials takes a lot of time and human efforts [2]. An alternative is to develop a digital teacher. We have developed a prototype of a synthetic 3D face that shows emotion associated to text...

New results on scale effects for wave overtopping at coastal structures, the CLASH programme

It is proven that wave run up on rough slopes is underestimated in small scale model tests due to scale / model effects. Given this fact, the same effects are suspected to be present for wave overtopping. A thorough comparison between prototype measurements of wave overtopping at three different coastal structures and scale model tests of these...

Voorspelling van golfoverslag over golfbrekers en zeeweringen met behulp van neurale netwerken - Neural Network Prediction of Wave Overtopping at Coastal Structures

Development of a neural network based on a large database of field and laboratory data in order to calculate overtopping. Comparison with existing formulas.

Report on additional tests – Part C: Influence of low wave steepness

Within the framework of the CLASH-white spot tests, wave overtopping tests on a smooth sloping structure have been performed at UGent. 3 different geometries have been tested during these tests 1) simple smooth dike 2) simple smooth dike with a small vertical part (same crest level as geometry 1) 3) simple smooth dike with a small vertical part...

Sytnthesis and design guidelines for overtopping

The CLASH project (Crest Level Assessment of Coastal Structures by Full Scale Monitoring, Neural Network Prediction and Hazard Analysis on Permissible Wave Overtopping, www.clash-eu.org) funded by European Union (EU) through contract no. EVK3-CT-2001- 00058, investigated wave overtopping for different structures in prototype and in laboratory ...

Socio-economic impacts of wave overtopping

This report provides a methodological background that will be used in the assessment of hazards of overtopping. Those assessment methods that attach a monetary value to the effects on resources are focussed upon. The relationships between the characteristics of overtopping and the use of specific valuation techniques is further explored....

Final report on laboratory measurements on the Ostia case

Within WP4.2 laboratory investigations for the Ostia rubble mound breakwater are performed in the wave flume of Ghent University (later UGent) and in the wave basin of Flanders Hydraulics (hereafter FCFH). In order to check any influence that is typical for laboratory measurements and to identify possible causes for differences in results, tests...

Report on full scale measurements in Zeebrugge, 2nd full winter season

The present report describes the full scale measurements at the Zeebrugge breakwater within the framework of Workpackage 3: Full Scale Measurements of the CLASH-project. First a general description of the field site is given. Afterwards, two types of full scale measurements are described: on the one hand the wave overtopping measurements and on...

Free surface numerical modelling of wave interaction with coastal structures

The main objective of Workpackage 5 is to use numerical simulation of wave overtopping in order to solve the problem of suspected scale effects. A second, related, objective is to improve existing codes in such a way as they are able to simulate wave overtopping in a reliable way. The final, single, objective is to numerically model long waves...

Golfoploop op stortsteengolfbrekers: Wave run-up on rubble mound breakwaters

Study on wave runup on a permeable rubble mound breakwater with antifer cubes as armour unit. Comparison of literature data with prototype measurement on the Zeebrugge breakwater and with data in laboratory experiments on different scales. Relation between wave runup and the pattern of the cubes. Some influence of the width of the spectrum was...

The optimisation of crest level design of sloping coastal structures through prototype monitoring and modelling, final report

This text introduces the ‘Detailed scientific and technical report’ of the MAST III project MAS03- CT97-0116 ‘The optimisation of crest level design of sloping coastal structures through prototype monitoring and modelling’ (acronym: OPTICREST). This report gives an account of the detailed scientific and technical outcome of the project referring...

Experimentele studie en numerieke modellering van golfinteractie met stortsteengolfbrekers

Description of a VOF model for wave structure interaction (VOF-break). Example calculations for the Zeebrugge breakwater, including prototype measurements of wave penetration into the core of the breakwater. Description of breaking processes on the breakwater.

Wave run-up on a rubble mound breakwater: Prototype measurements versus scale model tests

Wave run-up on a rubble mound breakwater is investigated. Prototype measurements are carried out on the Zeebrugge breakwater. Two 2D (1:30) and one 3D (1:40) scale models are tested. Measured prototype storms are simulated and parametric tests are performed. Wave run-up is detected by a novel step gauge allowing to detect wave run-up more...
