  2. 1. Shape Matters : Characterization of Weak Interactions and Macrocycles by Conformational Analysis

    Author : Stefan Peintner; Máté Erdélyi; Oliver Zerbe; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : When studying conformational ensembles, it is most challenging to identify and characterize rapidly interconverting individual conformers. A precise description of the structural dynamics, however, rewards viable knowledge on conformation stabilizing forces as well as on the impact of external influences on the conformer composition.

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape modeling; deformable models; principal component analysis; echocardiography; snakes; active shape models; deformable spatio-temporal shape models; medial-based shape profiles; statistical shape variation; spatio-temporal shape analysis; magnetic resonance imaging; hierarchical regional principal component analysis; oral lesions; dynamic programming; segmentation; spring-mass model; shape deformation; optical flow; medical image analysis; artificial life; physics-based modeling; deformable organisms; digital color images; medial axis; active contour models;

    Abstract : Medical imaging continues to permeate the practice of medicine, but automated yet accurate segmentation and labeling of anatomical structures continues to be a major obstacle to computerized medical image analysis (MIA). Deformable models, with its profound roots in estimation theory, optimization, and physics-based dynamical systems, represent a powerful approach to the general problem of medical image segmentation.

  6. 4. Automatic Shape Modelling with Applications in Medical Imaging

    Author : Anders Ericsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heart-infarction; lung-embolie; Parkinson; DaTSCAN; SPECT; SCINT; affine shape; MDL; automatic shape models; Deformable models; active shape; Mathematics; Matematik;

    Abstract : This thesis consists of two parts. The first part is devoted to automatic shape analysis and the second part is devoted to decision support systems in medical imaging. Shape models are widely used in segmentation and shape analysis. The thesis begins with a review of deformable models and the preliminaries of shape modelling. READ MORE

  7. 5. Shaping of Food Microstructures

    Author : Lars Hamberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; food microstructure; flow; emulsion; carrageenan whey protein isolates; shaping; aggregate; gelatine; suspension; gel formation; particle; Fourier shape description; shape; shape measurements;

    Abstract : Shape, the shaping process and the functionality of shape for food microstructure are the focus of this thesis. Shape is one of the parameters that influences the microstructure functionality; hence microstructure shape optimisation is an interesting task in the development of new functional materials and processes, especially for food, in which structure-related texture is an essential part of the product.
