Feasibility Study & Embodiment Design of a More Efficient Frying Pan for Commercial Kitchens

This design report discusses the embodiment design of a more efficient frying pan for gas powered stoves in commercial kitchens, to see if a potential market entry is feasible, viable and desirable. Conventional pans have a thermal efficiency of roughly 25%. This means that only 25% of the heat coming from the combusted gas is used for cooking....

Optoelectronic control of cardiac rhythm: Toward shock-free ambulatory cardioversion of atrial fibrillation

Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia, progressive in nature, and known to have a negative impact on mortality, morbidity, and quality of life. Patients requiring acute termination of AF to restore sinus rhythm are subjected to electrical cardioversion, which requires sedation and therefore hospitalization due to...

Implementation of an automated Systems Engineering Toolset in the DST project

In the DST project, a deployable space telescope is designed for the thermal infrared spectrum. For this project, a new Systems Engineering (SE) approach was needed, since the SE was outdated and the project worked in silos. Important goals for the SE approach were that it was easy to use and minimizes the workload by automating as much as...

The Ethical Dimension of Emerging Technologies in Engineering Education

Emerging technologies are part of the constituting datafication and digitalization process that poses major challenges to the current educational infrastructure. Clearly, universities are challenged to respond to the demands that seem to develop faster and become more complex over time. The complexity, though, is not just technical; it is the...

Quays Rather Than Boilers: Extracting Heat From Water and Soil Through Energy Sheet Piles

As part of the effort to make the Dutch waterways CO2-neutral, a consortium consisting of, among others, CRUX Engineering BV and Delft University of Technology, initiated a case study in which the thermal and mechanical performance of an energy sheet pile wall is studied. This technology allows for the extraction of energy from the water and...

Observed Changes of a Mega Feeder Nourishment in a Coastal Cell: Five Years of Sand Engine Morphodynamics

Recently, mega feeder nourishments have been proposed as a new strategy to nourish sediment-starving beaches. This strategy involves the placement of a large, concentrated sediment volume at a single location along the coast. Wind, waves and currents act as the natural agents to spread the sediment alongshore over the course of years to decades....

A specialised delivery system for stratospheric sulphate aerosols: design and operation

Temporary stratospheric aerosol injection (SAI) using sulphate compounds could help to mitigate some of the adverse and irreversible impacts of global warming. Among the risks and uncertainties of SAI, the development of a delivery system presents an appreciable technical challenge. Early studies indicate that specialised aircraft appear the...

Safe and effective application of ammonia as a marine fuel

To achieve significant reduction in greenhouse gas emissions in shipping and enable ship owners to phase out fossil fuels entirely, renewable fuels, such as ammonia, play a crucial role. Ammonia is considered a balanced solution in terms of volumetric energy density and renewable synthetic production cost compared to other renewable fuels....

Towards efficient perfusion recellularization of porcine liver grafts with liver-derived organoids

Currently, the only effective treatment for end-stage liver diseases is liver transplantation. However, the waiting list with patients who are in need of a new liver is long, because too few good-quality donor livers are available. New techniques in the field of tissue engineering are being investigated to create a reconstructed liver, which...

On the accuracy of automated shoreline detection derived from satellite imagery: A case study of the Sand Motor mega-scale nourishment

Measured trends and variability in shoreline position are used by coastal managers, scientists and engineers to understand and monitor coastal systems. This paper presents a new and generic method for automated shoreline detection from the largely unexplored collection of publicly available satellite imagery. The position of the obtained...

Long term coastline monitoring derived from satellite imagery

Measured gradientsin alongshore sediment transport along the Dutch coast

In this paper it is aimed to quantify bulk (surf-zone integrated) alongshore sediment transport using morphological data collected along the Dutch coast. The collected morphological data covers a domain of 18 km alongshore including the beach, the foreshore and the intertidal zone in the cross shore. The measurement domain contains the 20...
