The potential role of wood acetylation in climate change mitigation

In a carbon footprint assessment, the greenhouse gas emissions during the life cycle of a material can be measured, and compared to alternative products in terms of kg CO2 equivalent. If applied correctly, wood acetylation opens up a range of new innovative applications in which high performance yet carbon intensive non-renewable materials such...

Region based level set segmentation of the outer wall of the carotid bifurcation in CTA

This paper presents a level set based method for segmenting the outer vessel wall and plaque components of the carotid artery in CTA. The method employs a GentleBoost classification framework that classifies pixels as calcified region or not, and inside or outside the vessel wall. The combined result of both classifications is used to construct...

Multispectral MRI centerline tracking in carotid arteries

We propose a minimum cost path approach to track the centerlines of the internal and external carotid arteries in multispectral MR data. User interaction is limited to the annotation of three seed points. The cost image is based on both a measure of vessel medialness and lumen intensity similarity in two MRA image sequences: Black Blood MRA and...

Coordination in railway hinterland chains: An institutional analysis

In the last two decades, the European railway market has been liberalized: more competition and less government involvement should lead to higher efficiencies. The central message from an economic perspective is that more market coordinates trans- actions more effectively and efficiently. In the rail freight market, liberalization did bring...
