2. 1. Theory of transformation optics and invisibility cloak design

   Author : Pu Zhang; Sailing He; Hao Yang; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transformation optics; Maxwell’s equations; invisibility cloak; half-space cloak; reduced cloak; inverse transformation; carpet cloak; Electrical engineering; Elektroteknik;

   Abstract : Research on metamaterials has been growing ever since the first experimental realization of double negative media. The theory of transformation optics provides people with a perfect tool to make use of vast possibilities of the constitutive parameters for metamaterials. READ MORE

4. 2. Development of a Whole Body Atlas for Radiation Therapy Planning and Treatment Optimization

   Author : Sharif Qatarneh; Anders Brahme; Bengt Lind; Anders Ahnesjö; Stockholms universitet; []
   Keywords : 3D whole body atlas; lymph node topography; matching transformation; radiation therapy planning; radiobiological optimization; segmentation; target volume definition; medicinsk strålningsfysik; Medical Radiation Physics;

   Abstract : The main objective of radiation therapy is to obtain the highest possible probability of tumor cure while minimizing adverse reactions in healthy tissues. A crucial step in the treatment process is to determine the location and extent of the primary tumor and its loco regional lymphatic spread in relation to adjacent radiosensitive anatomical structures and organs at risk.

5. 3. Extensions and Applications of Affine Shape

   Author : Rikard Berthilsson; Matematik LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Matematik; Mathematics; density of shape; maximum likelihood; matching constraint; surface; curve; handwriting; recognition; affine shape; reconstruction; computer technology; Data- och systemvetenskap;

   Abstract : A central problem in computer vision is to reconstruct the three-dimensional structure of a scene from a set of two-dimensional images. Traditionally this is done by extracting a set of characteristic points in the scene and to compute a reconstruction of these points. READ MORE

6. 4. Effective vibro-acoustical modelling of rubber isolators

   Author : Michael Coja; Leif Kari; Wolfgang Kropp; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; Rubber isolator; Bush mounting; Dynamic stiffness; Waveguide; Fractional derivatives; Mode-matching; Pre-compressed; Prestrain; Preload; Predeformation; Viscoelasticity; Dispersion; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

   Abstract : This thesis, gathering four papers, concerns the enhancement in understanding and modelling of the audible dynamic stiffness of vibration rubber isolators including experimental measurements. Paper A studies the performances of three different types of vibration isolator using an indirect measurement technique to estimate the blocked dynamic transfer stiffness of each specimen. READ MORE

7. 5. Co-constructing Expertise : Competence Development through Work-Integrated e-Learning in joint Industry-University Collaboration

   Author : Monika Hattinger; Lars Svensson; Maria Spante; Lennart Malmsköld; Kristina M. Eriksson; Linn Gustavsson Christiernin; Anita Mirijamdotter; Högskolan Väst; []
