Planning the route to higher bus quality: Creating a roadmap for effective implementation of high-quality bus systems in the Netherlands

The transport sector needs to change to meet some of the global challenges we face: climate change, population growth and urbanisation. It needs to become more sustainable, which is why the Netherlands wants to introduce more high-quality bus systems. However, there are some barriers to implementing these systems.<br/><br/>In this thesis,...

Literature survey on improving type checker efficiency without altering the surface language

Type checkers are invaluable tools which help programmers write correct programs. Fast and efficient type checkers are required to enable adoption of such tools in practice.<br/><br/>This study aims to provide an explorative overview of proposed efficiency improvements for type checkers. This provides language implementers insight in what...

Performance assessment of the Ocean Falls Wave Energy Converter: A solution for electrical power production in the future

There is a growing demand for renewable sources of energy of which wave energy conversion is one. The Ocean Falls is an oscillating water column (OWC) system invented by BAM Infraconsult b.v. This system differs from conventional OWC systems since it includes a connection tube and an adjustable back wall. The OWC system is a resonance system for...

Synthesizing an implementation framework for responsible research and innovation

The concept of Responsible Research &amp; Innovation (RRI) seems to gain initial momentum. The lack of collective meaning however, results in a plethora of publications, which describe RRI from ad hoc perspectives. To provide a robust foundation for scholars and practitioners seeking to implement RRI, we aim to integrate those perspectives...

Fully controlled photonic spin in highly confined optical field

As an intrinsic attribute of light, the spin angular momentum (SAM) of photons has aroused considerable attention because of the fascinating properties emerging from light–matter interactions. We show that a diffraction-limited focal field with a steerable photonic spin structure in three dimensions can be produced under a 4π microscopic...

On the anatomy of social engineering attacks: A literature-based dissection of successful attacks

The aim of this study was to explore the extent to which persuasion principles are used in successful social engineering attacks. Seventy-four scenarios were extracted from 4 books on social engineering (written by social engineers) and analysed. Each scenario was split into attack steps, containing single interactions between offender and...

A New Definition of Capillary Numbers In Microfluidic Devices

The mobilization of the trapped residual oil is an important part of Enhanced Oil Recovery. The desaturation of nonwetting fluids from porous media is often described using capillary numbers which are a ratio of viscous forces over the capillary forces between the wetting and the nonwetting fluids. Twodimensional microfluidic devices ...

Log Analysis from A to Z: A Literature Survey

Using logs to detect and diagnose problems in software systems is no longer a feasible human process. The ever increasing amount of logs produced by present-day systems calls for more advanced techniques to enable log analysis. A great deal of log research has since then been focused on abstracting over log messages, clever analysis techniques...

Bed-load formulae for non-uniform sediment

A bed-load sediment transport formula has ben devlopd for every fraction of the sediment mixture. All existing bed-load formula have been reanalysed on their application for this purpose (Kalinske, Einstein, Meyer-Peter and Muller) as well as adaptations by different other authors
