  4. 2. Adaptivity for Stochastic and Partial Differential Equations with Applications to Phase Transformations

    Author : Erik von Schwerin; Anders Szepessy; Desmond Higham; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; Numerisk analys;

    Abstract : his work is concentrated on efforts to efficiently compute properties of systems, modelled by differential equations, involving multiple scales. Goal oriented adaptivity is the common approach to all the treated problems. READ MORE

  5. 3. On Detection and Estimation of Multiple Sources in Radar Array Processing

    Author : Jonny Eriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spatially correlated noise; Cramer-Rao bounds; estimation; feature reduction; virtual uniform linear arrays; classification; adaptive data reduction; nonlinear weighted least squares; multiple targets; detection;

    Abstract : This thesis deals with detection and estimation problems in sensor array signal processing. We treat the multiple hypothesis problem for complex sinusoids observed in spatially colored noise. READ MORE

  6. 4. Subband Beamforming for Speech Enhancement within a Motorcycle helmet

    Author : Per Cornelius; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamfroming; Microphone array system;

    Abstract : The increased mobility in society has led to a need for convenient mobile communication in many different type of environments. Environments such as a motorcycle helmet, engine rooms and most industrial sites share a common challenge in that they often offer significant acoustic background noise. READ MORE

  7. 5. Parameter Estimation in Linear Descriptor Systems

    Author : Markus Gerdin; Linköpings universitet; []
    Keywords : differential-algebraic equations; descriptor systems; identification; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Linear descriptor systems form the natural way in which linear models of physical systems are delivered from an object-oriented modeling tool like Modelica. Linear descriptor systems are also known as linear differential-algebraic equations in the continuous-time case. READ MORE
