Towards Small-Baseline InSAR Time Series Analysis for Volcanic Monitoring on Saba and St. Eustatius

Over the years, InSAR has become an indispensable tool in the study of ground deformation, including volcanic deformation, and this continues to be the case in times of improved technology. Since the volcanoes on the Caribbean islands of Saba and St. Eustatius are active, the implementation of an InSAR-based monitoring system is crucial to...

Sarakshit Ghar: A Safe Home: Documenting the changes in earthquake-resistant construction elements in the housing of the Kathmandu Valley in the period of 1769 - 2023

Being a highly earthquake-prone country, Nepal gets hit by a major earthquake roughly every 80-100 years. The recent major tremor in 2015 showed how the houses in the Kathmandu Valley were not ready: 9000 lives and half a million houses were lost. <br/>This thesis describes the changes in earthquake-resistant elements in the residential...

Numerieke simulatie van een bewegend randprobleem voor plaque-ontwikkeling bij atherosclerose: Een onderzoek naar de invloed van shear stress op de plaquevorming

In dit verslag wordt onderzoek gedaan naar het verloop van de ziekte Atherosclerose. Dit is een ziekte waarbij de wand van het bloedvat uitzet en verhardt. Dit gebeurt doordat er in de bloedwand ophoping plaatsvindt van plaque, bestaande uit LDL-deeltjes, immuuncellen en foam cellen. In dit onderzoek wordt gekeken hoe deze plaquevorming zal gaan...

Methodically improving assembly lines: A bicycle assembly case study

The bicycle production company Accell-group N.V. aims to improve their bicycle assembly lines. The assembly of bicycles requires fastening a large amount of parts using a variety of fastening techniques. In the investigated situation, these assembly operations are performed on an assembly line. The goal of this thesis is to structurally improve...

Geotextile tubes filled with mine tailings as a construction element

Large quantities of mine tailings are stored in mine tailings storage facilities. These facilities are only costing money for mining companies. In addition, these tailings storage facilities are prone to failure. To prevent this from happening these facilities have to be reinforced. This research introduces a concept to use geotextile tubes...

Future Urban Ferry: A conceptual study of power and propulsion using zero-emission energy storage devices

The aim of this thesis is to investigate whether energy storage devices can be used in order to reduce the local, harmful, polluting emissions of an urban ferry. This is investigated by modeling zero emission energy storage devices (ESDs) in the power and propulsion configuration of a benchmark urban ferry. This benchmark ferry provides the...

Changed mobility behaviour of young adults in the Netherlands - Improving the mobility image of young adults based on the OVG 2002/2003 and MON 2007/2009 dataset

In recent literature an emerging need of understanding the changed mode choice of young adults (aged 18 to 29) is revealed. International literature reveals different characteristics that influence the modal split of young adults, but a quantitative research on the changes in preference of these young adults, as basis of a deeper understanding...

Globally Optimal Multivariate Splines: Optimizing B-coefficient and vertex coordinates of simplex splines using interval analysis

In applications like model identification accurate methods for data approximation are required. Multivariate simplex B-splines form a class of nonlinear function approximators capable of approximating scattered data. Simplex B-splines are piecewise polynomials defined on a triangulation. Currently, data approximation using simplex B-splines is...

From parts to products: Using a wastestream for new product development

For this research a pilot project is conducted focusing on the wood wastestream from the consumer market. The waste generation growth is higher than the population growth due to increased consumption. Therefore, keeping materials in continuous loops for efficient waste management and to provide the materials for future generations gains...

Velocity and flow depth variations during wave overtopping

Nowadays the protection of our country for high sea levels and heavy storms is daily news. The ComCoast project (COMbined functions in the COASTal defence zones) is originated by ten organisations out of five European countries bordering the North Sea coasts in order to develop innovative solutions for flood protection in coastal areas. Instead...

Modellering van extreme waterstanden veroorzaakt door opwaaiing toegepast op het Slotermeer: Een toetsing van het model voor overschrijdingswaterstanden in Friesland met een berekening van opwaaiing op het Slotermeer

De provincie Friesland wil een meer gestructureerde aanpak voor de bepaling van de hoogtes van boezemkades. Om goed te kunnen dimensioneren is een gedetailleerd model nodig met maatgevende waterstanden. Het huidige model, gemaakt door het Wetterskip Fryslân, is gebaseerd op 37 meetpunten verspreid over Friesland. Met de metingen zijn voor de...

Fieldwork Coastal Engineering: Varna (Bulgaria)

For the course CT5318 a trip is made to Varna, Bulgaria, where hydraulic measurement s on the beach and the coastal structures are executed by the students. This report describes the measured data, the used methods and the technical interpretation of the results. All the data was processed in Varna and analysed once returned in the Netherlands....

Aspects of sea navigation

This paper investigates three topics which play a role in the adjustment and testing of offshore navigation data. All these three aspects are more or less related to the NAVGRAV project (NAVigation-GRAVitation) which will take place in 1986. First, the preci si on of various radiopositioning systems is elaborated. For the computation of the...
