  1. 6. On Multidimensional Dynamic Fluorescence Imaging and Quantitative Image Analysis in Wide-Field Microscopy Applications to Studies of Astroglial Cells

    Författare :Siamak Khatibi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; volume estimation; astrocyte; calcium wave; intercellular signaling; volumetric image analysis; fluorescence imaging; three-dimensional 3D reconstruction; segmentation;

    Sammanfattning : Modern biological research has benefited from a renaissance in light microscopy, brought about by the convergence of developments in fields as diverse as electronics, optics, molecular biology, computer science, and reagent chemistry. Integration of these has transformed microscopy into a highly useful, dynamic research tool for biology and medicine. LÄS MER

  3. 7. Finite element methods for threads and plates with real-time applications

    Författare :Karl Larsson; Mats G. Larson; Peter Hansbo; Umeå universitet; []
    Nyckelord :finite element method; real-time simulation; absolute nodal continuous formulation; large deformation; corotation; adaptive resolution; Kirchhoff-Love plate; reconstruction; discontinuous Galerkin; a priori error estimation; Mathematics; matematik;

    Sammanfattning : Thin and slender structures are widely occurring both in nature and in human creations. Clever geometries of thin structures can produce strong constructions while using a minimal amount of material. LÄS MER

  4. 8. Extensions and Applications of Affine Shape

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Matematik; Mathematics; density of shape; maximum likelihood; matching constraint; surface; curve; handwriting; recognition; affine shape; reconstruction; computer technology; Data- och systemvetenskap;

    Sammanfattning : A central problem in computer vision is to reconstruct the three-dimensional structure of a scene from a set of two-dimensional images. Traditionally this is done by extracting a set of characteristic points in the scene and to compute a reconstruction of these points. LÄS MER

  5. 9. Investigation on the self-healing capabilties of asphaltic materials using neutron imaging

    Författare :Adrian Markari; Nicole Kringos; Anders Kaestner; Romain Balieu; Lily Poulikakos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-healing; bituminous materials; neutron imaging; sample size effect; reconstruction; image processing; volumetric analysis; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Sammanfattning : Bitumen acts as a binding agent in asphalt mixtures where it binds the aggregates together. It is known for its potential to heal small cracks and recover its mechanical properties under the right conditions. Though this self-healing property is known, there is currently a lack of knowledge about the mechanisms that drive the process. LÄS MER

  7. 10. Cone-Beam Reconstruction Using Filtered Backprojection

    Författare :Henrik Turbell; Per-Erik Danielsson; Michel Defrise; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The art of medical computed tomography is constantly evolving and the last years have seen new ground breaking systems with multi-row detectors. These tomographs are able to increase both scanning speed and image quality compared to the single-row systems more commonly found in hospitals today. LÄS MER
