A Watermark Recognition System: An Approach to Matching Similar Watermarks

Watermarks are historical motifs present in the texture of paper that are commonly used to identify the paper manufacturers. They only become visible when viewed under certain light conditions. Under ideal circumstances, researchers may use watermarks to determine a historical document’s origins and context. To identify a watermark, it is...

Reinforcing data bias in crisis information management: The case of the Yemen humanitarian response

The complex and uncertain environment of the humanitarian response to crises can lead to data bias, which can affect decision-making. Evidence of data bias in crisis information management (CIM) remains scattered despite its potentially significant impact on crisis response. To understand what biases emerge in complex crises and how they affect...

Synthesizing an implementation framework for responsible research and innovation

The concept of Responsible Research & 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...

Towards Software Component Procurement Automation

One of the first steps of component procurement is the identification of required component features in large repositories of existing components. On the highest level of abstraction, component requirements as well as component descriptions are usually written in natural language. Therefore, we can reformulate component procurement as a text...

Development of a computerized handbook of architectural plans, Ontwikkeling van een gecomputeriseerd handboek van architectonische plattegronden

The dissertation investigates an approach to the development of visual / spatial computer representations for architectural purposes through the development of the computerized handbook of architectural plans (chap), a knowledge-based computer system capable of recognizing the metric properties of architectural plans. This investigation can be...
