    Sammanfattning : To meet increasing demands in electric energy, it is essential to enhance production of electricity from renewable energy sources (solar, wind and hydro). Such generation sites, however, are usually separated from consumption sites by long distances. LÄS MER

  5. 5. Non-invasive Functional Neuroimaging for Localizing Epileptic Brain Activity

    Detta är en avhandling från Signal Processing Group, Dept. of Electrical Engineering and Computer Science, Box 118, S-221 00 Lund

    Författare :Yazdan Shirvany; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mathematical Dipole; Finite Element Method; Source localization; Structural Magnetic Resonance Imaging; Forward Problem; Inverse Problem; Particle Swarm Optimization; Non-invasive EEG; Somatosensory Evoked Potentials; Epileptic Spike; Functional Neuroimaging;

    Sammanfattning : Surgical therapy has become an important therapeutic alternative for patients with medically intractable epilepsy. Correct and anatomically precise localization of the epileptic focus, preferably with non-invasive methods, is the main goal of the pre-surgical epilepsy diagnosis to decide if resection of brain tissue is possible.
