  1. 16. Spectral signature measurements and image processing for geological remote sensing

    Author : Kjell Wester; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; naturgeografi; Physical Geography;

    Abstract : This work focuses on (i) spectral signatures of rocks and lichens, and on the use of satellite images for (ii) survey mapping of areas dominated by exposed bedrock, (iii) bedrock mapping and mineral prospecting.(i) Laboratory measurements demonstrate that a lichen cover can significantly mask the spectral reflectance of rocks.

  2. 17. Integer Quadratic Programming for Control and Communication

    Author : Daniel Axehill; Anders Hansson; Manfred Morari; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integer Quadratic Programming; Model Predictive Control; Hybrid Systems; Semidefinite Programming; Code Division Multiple Access; Multiuser Detection; Automatic Control; Communication; Automatic control; Reglerteknik;

    Abstract : The main topic of this thesis is integer quadratic programming with applications to problems arising in the areas of automatic control and communication. One of the most widespread modern control methods is Model Predictive Control (MPC). In each sampling time, MPC requires the solution of a Quadratic Programming (QP) problem. READ MORE

  3. 18. Decision Support for Estimation of the Utility of Software and E-mail

    Author : Anton Borg; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Background: Computer users often need to distinguish between good and bad instances of software and e-mail messages without the aid of experts. This decision process is further complicated as the perception of spam and spyware varies between individuals. READ MORE

  4. 19. Applications of Integer Quadratic Programming in Control and Communication

    Author : Daniel Axehill; Anders Hansson; Anders Rantzer; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; Model Predictive Control; CDMA; Quadratic Programming; Mixed Integer Quadratic Programming; Dual active set methods; Riccati recursion; Branch and bound; Automatic control; Reglerteknik;

    Abstract : The main topic of this thesis is integer quadratic programming with applications to problems arising in the areas of automatic control and communication. One of the most widespread modern control principles is the discrete-time method Model Predictive Control (MPC). READ MORE

  5. 20. Multifont recognition System for Ethiopic Script

    Author : Yaregal Assabie Lake; Josef Bigun; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ethiopic character recognition; OCR; Multifont recognition; Amharic; Direction fields; Structural and syntactic pattern recognition; Image analysis; Bildanalys;

    Abstract : In this thesis, we present a general framework for multi-font, multi-size and multi-style Ethiopic character recognition system. We propose structural and syntactic techniques for recognition of Ethiopic characters where the graphically comnplex characters are represented by less complex primitive structures and their spatial interrelationships.
