  2. 1. Interest Curves : Concept, Evaluation, Implementation and Applications

    Author : Bo Li; Ulrik Söderström; Haibo Li; Björn Kruse; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scale-invariance; edge; corner; curve; line; matching; object detection; signalbehandling; Signal Processing;

    Abstract : Image features play important roles in a wide range of computer vision applications, such as image registration, 3D reconstruction, object detection and video understanding. These image features include edges, contours, corners, regions, lines, curves, interest points, etc. READ MORE

  4. 2. Development and Application of Laser-Induced Emission Techniques for Combustion Diagnostics -High-Resolution Visualization of Turbulent Reacting Flows

    Abstract : Nowadays, more than 90% of our energy comes from combustion processes. Hence, it is very important to perform combustion research to reduce emissions, improve efficiency, find clean and renewable fuels, strengthen safety, etc. READ MORE

  5. 3. Chloride Transport in Concrete under the Frost Action – An Experimental Study

    Author : Bo Li; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; chloride; concrete; freeze-thaw cycles; water uptake; chloride profile; frost action; transport;

    Abstract : Frost-induced ingress of chloride in concrete is one of the typical transport phenomena of aggressive substances when structures expose to severe environments such as marine tidal zone and de-icing highway in winter seasons. It is well known that Chloride ingress in concrete causes the reinforcement corrosion. READ MORE

  7. 5. Collective Excitations in Transitional Nuclei Studied by Means of gamma-ray Spectroscopy and Lifetime Measurements

    Author : Hongjie Li; Bo Cederwall; Radomira Lozeva; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Despite that it is more than 100 years since the atomic nucleus was first dis- covered by Ernest Rutherford and coworkers, many of its features still elude our understanding. The fact that the fundamental interactions between the nuclear constituents; nucleons, and ultimately quarks, are not yet known in detail, and the complexity of the nuclear many-body system compound the great challenges facing theoretical interpretations of experimental data.
