Imaging CO₂ reinjection into basalts at the CarbFix2 reinjection reservoir (Hellisheiði, Iceland) with body-wave seismic interferometry

As part of the Synergetic Utilisation of CO (Formula presented.) storage Coupled with geothermal EnErgy Deployment project, investigating CO (Formula presented.) reinjection with different seismic methods, both passive and active seismic surveys have been conducted at the geothermal power plant at Hellisheiði, Iceland. During the 2021 survey,...

Identifying patterns and recommendations of and for sustainable open data initiatives: A benchmarking-driven analysis of open government data initiatives among European countries

Open government and open (government) data are seen as tools to create new opportunities, eliminate or at least reduce information inequalities and improve public services. More than a decade of these efforts has provided much experience, practices, and perspectives to learn how to better deal with them. This paper focuses on benchmarking of...

A fully automated approach to calculate the melting temperature of elemental crystals

The interface method is a well established approach for predicting melting points of materials using interatomic potentials. However, applying the interface method is tedious and involves significant human intervention. The whole procedure involves several successive tasks: estimate a rough melting point, set up the interface structure, run...

A Multi-Criteria Analysis on Digitizing Services in the Port of Rotterdam

The purpose of this master thesis was to explore in which way the service of Vopak Agencies could be digitized and be accepted by the client the most.

A Comparative Study of Methods for Deciding to Open Data

Governments may have their own business processes to decide to open data, which might be supported by decision-making tools. At the same time, analyzing potential benefits, costs, risks, and other effects-adverse of disclosing data are challenging. In the literature, there are various methods to analyze the potential advantages and...

Evaluating an mHealth App for Health and Well-Being at Work: Mixed-Method Qualitative Study

Background: To improve workers’ health and well-being, workplace interventions have been developed, but utilization and reach are unsatisfactory, and effects are small. In recent years, new approaches such as mobile health (mHealth) apps are being developed, but the evidence base is poor. Research is needed to examine its potential and to assess...

Standards battles for business-to-government data exchange: Identifying success factors for standard dominance using the Best Worst Method

Businesses are obliged to report all kinds of data to the government. In the past this was paper-based, and over time Electronic Data Interchange (EDI) types of solutions have been implemented. The new eXtensible Business Reporting Language (XBRL) standard seems to have replaced EDI types of solutions. This paper applies the Best Worst Method...

Laparoscopic hysterectomy for benign indications: clinical practice guideline

Purpose: Since the introduction of minimally invasive gynecologic surgery, the percentage of advanced laparoscopic procedures has greatly increased worldwide. It seems therefore, timely to standardize laparoscopic gynecologic care according to the principles of evidence-based medicine. With this goal in mind—the Dutch Society of Gynecological...

Efficient optimization method for the light extraction from periodically modulated LEDs using reciprocity

The incoherent emission of periodically structured Light Emitting Diodes (LEDs) can be computed at relatively low computational cost by applying the reciprocity method. We show that by another application of the reciprocity principle, the structure of the LED can be optimized to obtain a high emission. We demonstrate the method by optimizing one...

An integrated approach for financial and environmental cost optimisation of heating services

A four-year project has started in 2007 to develop a methodology that can be applied to optimize the Belgian dwelling stock. The aim of the project is to optimise buildings concerning their environmental impact, their financial cost and the quality they offer over the whole life cycle, from the production of primary raw materials to the final...

Vectorial aerial-image computations of three-dimensional objects based on the extended Nijboer–Zernike theory

We present details of a novel imaging algorithm based on the extended Nijboer–Zernike (ENZ) theory of diffraction. We derive integral expressions relating the electric field distribution in the entrance pupil of an optical system to the electric field in its focal region. The evaluation of these integrals is made possible by means of a highly...

General imaging of advanced 3D mask objects based on the fully-vectorial Extended Nijboer-Zernike (ENZ) theory

In this paper we introduce a new mask imaging algorithm that is based on the source point integration method (or Abbe method). The method presented here distinguishes itself from existing methods by exploiting the through-focus imaging feature of the Extended Nijboer-Zernike (ENZ) theory of diffraction. An introduction to ENZ-theory and its...

Extended Nijboer–Zernike approach to aberration and birefringence retrieval in a high-numerical-aperture optical system

The judgment of the imaging quality of an optical system can be carried out by examining its through-focus intensity distribution. It has been shown in a previous paper that a scalar-wave analysis of the imaging process according to the extended Nijboer–Zernike theory allows the retrieval of the complex pupil function of the imaging system,...

Energieverloop en golfopstuwing bij brekende onregelmatige golven: Metingen en berekeningen

A description is given of a model developed for the prediction of the dissipation of energy in random waves breaking on a beach. The dissipation rate per breaking wave is estimated from that in a bore of corresponding height, while the probability of occurrence of breaking waves is estimated on the basis of a wave height distribution with an...
