Accelerating MA-XRF Data Acquisition by Exploiting Local Spatial and Spectral Relations within a Hyperspectral Datacube: An Approach through Wavelet Denoising

Macro X-ray fluorescence (MA-XRF) is a recently developed technology allowing to obtain elemental information from cultural heritage objects. This information can, for example, be used to identify pigments used in a painting. Yet, the extended period of time it takes to scan an object is a major issue within MA-XRf. For instance, it took about...

Loudspeaker filter optimization with AI: Electrical circuit representation, mutation and analysis for AI

This paper reports the design of a part of a genetic algorithm, which is made to design analog filters for loudspeakers. The part in this report is the part which deals with the representation of electrical filter circuits, the mutation of these filters, and finding their transfer function. The considered representations are graph coding and a...

Onvergelijkbare elementen in de Rudin-Keislerorde op βN

Deze scriptie gaat over βN. Wat specifieker: ze gaat over onvergelijkbare elementen in de Rudin-Keislerorde op βN. βN is een topologische ruimte, het is de Čech-Stone-compactificatie van de natuurlijke getallen. Er kan over βN echter ook op een meer verzamelingtheoretische manier worden nagedacht, namelijk als de familie van alle ultrafilters op...

Hydraulic load reduction as a function of depth in a filter layer consisting of logs

The formation of scour holes is a vital thread of retaining the water infrastructure of rivers. Nowadays, protective filters are used to prevent washing away of the underlying material. Rijkswaterstaat started the program 'Stroomlijn’, in which trees (logs) are cut from the floodplains and placed in a sheltered zone of the river to test whether...

Observing Solid Concentrations in a Vertical Hydraulic Transport System

At large oceans depths (5000m) manganese nodules are formed, these are rock shaped objects that contain various rare earth metals, Royal IHC is currently developing equipment to bring these nodules to the shore. The nodules will be transported to the water surface using a Vertical Transport System (VTS).<br/><br/>In the VTS insight of the...
