Innovative design and evaluation of a reusable drill guide for distal cement plug removal in total hip arthroplasty revision

Distal cement plug removal in total hip arthroplasty revision is a time-consuming and technically challenging procedure. There is a risk of perforating the femur while drilling in the cement plug. This risk increases when the orientation of the prosthesis tip is excentric. The aim of this study was to design a reusable drill guide that...

Decommissioning of Offshore Wind Turbines: A model-based approach to assess cost reducing decommissioning methodologies

The first large offshore wind farms installed in the North Sea Region (NSR) soon reach their technical end of lifetime. The wind turbines in these farms will have to be decommissioned after power production has stopped. Currently offshore wind turbines are decommissioned based on a method called reversed installation, a time consuming and...

GIS-based site suitability analysis for solar and win to hydrogen potential in Europe and Mediterranean region in 2030 and 2040

Today’s climate change creates a serious issue, which forces us to act by reducing Greenhouse Gas emissions across every sector. Making changes towards a sustainable world takes time and creates competition. Hydrogen has the potential to fuel a ‘clean’ economy because it is a carbon free energy carrier that can be produced from fossil fuels as...

Evaluation of Video Summarization using DSNet and Action Localization Datasets

In this paper, the DSNet framework used for automatic video summarization gets reviewed when using action localization datasets. The problem facing video summarizations using deep learning techniques is that datasets can be subjective depending on preferences of human annotators, making for noise in the labeling. This paper will look at a anchor...

Enabling the creation and hosting of cooperative online escape events in M.O.R.S.E. without programming experience

The M.O.R.S.E. system is a tool for creating and managing large escape events, mainly used for local escape events. The tool is designed for only a limited range of puzzle types and styling options because most of the puzzles require physical items in order to solve a puzzle and only the answers have to be entered in M.O.R.S.E. Because of this...

Morphological development of the Bollen van de Ooster: A potential hazard for Goeree-Overflakkee?

The Bollen van de Ooster, in this report referred to as the Ooster, is a sand bar in the outer delta of the Grevelingen. The Ooster is separated from the coast by a relatively deep channel, called the Schaar. Closure of the Grevelingen in 1971, with the construction of the Brouwersdam, initiated vast changes in morphology. Damming of the estuary...

Hydrological and hydrodynamic processes and their impact on spatial characteristics of Terminos Lagoon, Mexico

Terminos Lagoon is the biggest and ecologically most important fluvial-lagoon system of the southern Gulf of Mexico. Rivers, sea and meteorology all influence the lagoon, variable over the year, resulting in a complex situation. To protect this area, it is crucial to know how different hydrological processes, hydrodynamic processes and spatial...

Investigation of Vertical Cutter Mining for Increased Primary Resource Recovery and Decreased Environmental Impact: A VCM Study for De Beers, Victor Pipe, Canada

The purpose of this thesis is to aid in the development of vertical cutting mining as a mining method. In order to do so, the technical feasibility and viability, and environmental benefit of vertical cutting as a complementary mining method were investigated. The investigation was performed for the case of the Victor Diamond mine in northern...

Design of a Compliant, Multi-Phalanx Underactuated Prosthetic Finger

Highly advanced robotic hand prostheses are praised for their impressive grasping and pinching capabilities. Nevertheless, a high demand remains for grasping mechanisms that are cheaper to produce, easier to assemble and lower in overall maintenance. In this paper, the idea of creating a 3D printable underactuated grasper was realized to fulfill...

Factors influencing collaboration within a partnership of large infrastructural project in the Netherlands: An exploratory research into factors influencing collaboration according to an individual's view, in a specific formed centre of collaboration

Within the current Dutch construction industry, complex and extensive civil engineering projects are often executed by private partnerships, with a public client (the Dutch department of public works, better known as Rijkswaterstaat). Large projects in this context are considered multimillion euro projects, characterised as uncertain, complex,...

Declarative Access Control for WebDSL

This thesis describes the extension of WebDSL, a domain-specific language for web application development, with abstractions for declarative access control. The extension supports the definition of a wide range of access control policies concisely and transparently as a separate concern. Access is governed to the various resources in a WebDSL...
