    Sammanfattning : This thesis addresses a number of problems all related to parameter estimation in sensor array processing. The unifying theme is that some of these parameters are known before the measurements are acquired. LÄS MER

    Sammanfattning : This thesis investigates certain aspects of a six-dimensional quantum theoryknown as (2,0) theory. This theory is maximally supersymmetric and conformal,making it the most symmetric higher dimensional quantum theory known. It hasresisted an explicit construction as a quantum field theory yet its existence can beinferred from string theory. LÄS MER
