Routine maintenance of commercial aircraft requires reliable detection and repair of corrosion to ensure structural integrity. Post-repair inspections are commonly performed using manual ultrasonic point measurements of residual thickness, a process that is time-intensive and constrained by limitations …

Fluorescent Penetrant Inspection (FPI) is a widely used inspection technique in the aerospace industry. Because of the aging aerospace sector, and because of the safety-criticality of the inspection, aerospace companies aim to automate (parts of this) inspection process to support inspectors. This paper …

Innovating physical products can be seen as systems engineering at a higher abstraction level. It spans multiple domains and focuses not on developing the product, but realising the complete innovation. In our new approach, we focus on the four most important domains of physical product innovation: market, …

Abstract: The Problem-Solution Chain (PSC) models proposed in this exploratory paper are conceived as describing chains of problem-solution links, thereby modelling specific multi-link ‘problem-solving’ paths, typically (but not exclusively) from a high-level business problem to lower-level functional …

Geospatial technologies have the potential to transform the lives of older adults by providing them with necessary tools to navigate their local communities, access ser vices, connect with others, and access valuable information. However, the usability and accessibility of such technologies often fall …

In this abstract we describe a computational approach for detecting discursive patterns in social media. Newsrooms of municipalities and public organizations such as the police follow public debate on social media to be aware of and prepare for local and global issues and rumors. The onset of these issues …

Multi-faceted tasks can be completed in a linear start-to-finish fashion, or by completing the different facets parallel to each other. Either way, at some point the final additions and adjustments are made such that all the pieces fit together, and the task is completed properly. For example, baking …

Concrete is arguably the most widely used building material in the world today. Current estimates of world cement manufacture are of the order of 1.7*109 tons per year, enough to produce well over 6 km3 of concrete per year or at least 1 m3 per person (Gartner, 2004). It is a composite material made …

Lignocellulose biorefining is a promising technologyfor the sustainable production of chemicals and biopolymers.Usually, when one component is focused on, the chemical natureand yield of the others are compromised. Thus, one of thebottlenecks in biomass biorefining is harnessing the maximumvalue from …

This paper describes some explorations on the concept of disassemblability as an important circularity indicator for products because of its severe impact on reuse value. Although usefulness of the concept for determining disassembly strategies and for improving circular product design clearly shows …
