6. High-resolution diffusion-weighted brain MRI under motion
Abstract : Magnetic resonance imaging is one of the fastest developing medical imaging techniques. It provides excellent soft tissue contrast and has been a leading tool for neuroradiology and neuroscience research over the last decades. One of the possible MR imaging contrasts is the ability to visualize diffusion processes. READ MORE

7. Global Shape Description of Digital Objects
Abstract : New methods for global shape description of three-dimensional digital objects are presented. The shape of an object is first represented by a digital surface where the faces are either triangles or quadrilaterals. READ MORE

8. Advanced analysis of diffusion MRI data
Abstract : Diffusion magnetic resonance imaging (diffusion MRI) is a non-invasive imaging modality which can measure diffusion of water molecules, by making the MRI acquisition sensitive to diffusion. Diffusion MRI provides unique possibilities to study structural connectivity of the human brain, e.g. READ MORE

9. Structure, Bonding and Chemistry of Water and Hydroxyl on Transition Metal Surfaces
Abstract : The structure, bonding and chemistry of water and hydroxyl on metal surfaces are presented. Synchrotron based x-ray photoelectron- and x-ray absorption spectroscopy along with density functional theory calculations mainly form the basis of the results. READ MORE

10. Camera Modelling and Calibration with Machine Vision Applications
Abstract : Camera modelling and calibration are important parts of machine vision. They can be used for calculating geometric information from images. A camera model is a mathematical projection between a 3D object space and a 2D image. READ MORE
