The effects of fuel type and cathode off-gas recirculation on combined heat and power generation of marine SOFC systems

An increasing demand in the marine industry to reduce emissions led to investigations into more efficient power conversion using fuels with sustainable production pathways. Solid Oxide Fuel Cells (SOFCs) are under consideration for long-range shipping, because of its high efficiency, low pollutant emissions, and fuel flexibility. SOFC systems...

Probabilistic Risk Assessment of Urban Drainage Systems: Exploring Hanoi’s inundation problems using PCSWMM

This research explores the frequent urban flooding problems typically experienced in South-East Asian cities. Heavy rainfall during the monsoon period in combination with rapid urbanisation in the past decades causes an increasing amount of inundation events in the case study area Hanoi. The damage caused by these floods results in major...

Highly-conformal sputtered through-silicon vias with sharp superconducting transition

This paper describes the microfabrication and electrical characterization of aluminum-coated superconducting through-silicon vias (TSVs) with sharp superconducting transition above 1 K. The sharp superconducting transition was achieved by means of fully conformal and void-free DC-sputtering of the TSVs with Al, and is here demonstrated in up...

Integration of solid oxide fuel cell and internal combustion engine for maritime applications

The current literature on solid oxide fuel cell and internal combustion engine (SOFC-ICE) integration is focused on the application of advanced combustion technologies operating as bottoming cycles to generate a small load share. This integration approach can pose challenges for ships such as restricted dynamic capabilities and large space...

Evolution of the WebDSL runtime: Reliability engineering of the WebDSL web programming language

Web applications are ideal for implementing information systems; they can organize and persist the data in a database, do not require installation on client machines, and can be instantly updated everywhere. However, web programming is complex due to its heterogeneous nature, causing web frameworks to suffer from insufficient or leaky...

A process design for situations of temporal water scarcity in Rhine-Estuary Drechtsteden by implementing adaptive water management

During normal situations there is enough fresh water available for all functions in the Netherlands. But in times of droughts fresh water supply and water safety are at risk. For these periods of water scarcity, a sequence of priority on available fresh water distribution is present. However, experts consider that even these precautions are...

Low-Cost Technology for the Integration of Micro- and Nanochips into Fluidic Systems on Printed Circuit Board: Fabrication Challenges

Nowadays, micro- and nanochips are usually fabricated with Silicon and/or glass. A simple, low-cost and reliable integration packaging method that provides flexibility to the incorporation of electronic and fluidic devices into a system has not been fully developed yet. The use of Printed Circuit Board material as substrate to create dry film...

Static Consistency Checking of Web Applications with WebDSL

Modern web application development frameworks provide web application developers with highlevel abstractions to improve their productivity. However, their support for static verification of applications is limited. Inconsistencies in an application are often not detected statically, but appear as errors at run-time. The reports about these...

Domain-Specific Languages for Composable Editor Plugins

Modern IDEs increase developer productivity by incorporating many different kinds of editor services. These can be purely syntactic, such as syntax highlighting, code folding, and an outline for navigation; or they can be based on the language semantics, such as in-line type error reporting and resolving identifier declarations. Building all...

Energy integral method for gravity field determination from satellite orbit coordinates

A fast iterative method for gravity field determination from low Earth satellite orbit coordinates has been developed and implemented successfully. The method is based on energy conservation and avoids problems related to orbit dynamics and initial state. In addition, the particular geometry of a repeat orbit is exploited by using a very...
