3. 7. Hadron Physics in a Polarized World : Exploring Electromagnetic Interactions with Spin Observables

   Författare :Viktor Thorén; Andrzej Kupsc; Karin Schönning; Magnus Wolke; David Ireland; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron; Hyperon; Meson; Polarization; Spin observables; Electromagnetic interactions; BESIII; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

   Sammanfattning : The electromagnetic interactions of hadrons serve as a valuable probe of the nature of the strong force at low energies and simultaneously allow for tests of fundamental discrete symmetries. In this thesis, I show how polarization observables can be used to gain an in-depth understanding of these processes and present two analyses of data from the BESIII experiment where such observables have been studied.

4. 8. Radiant Textiles : Designing electromagnetic textile systems

   Författare :Erin Lewis; Tincuta Heinzel; Högskolan i Borås; []
   Nyckelord :HUMANIORA; HUMANITIES; smart textiles; electromagnetism; textile design; design methods; artistic research; Textiles and Fashion Design ; Textil och mode konstnärlig ;

   Sammanfattning : To regard the electromagnetic domain of conductive textiles is to unlock a realm of expressive possibilities. The underexplored area of the electromagnetic domain in con­ductive textiles implies that numerous computational and electronic textiles created thus far possess untapped capabilities. LÄS MER

5. 9. Linear wave energy converter : Study of electromagnetic design

   Författare :Erik Lejerskog; Mats Leijon; Giuseppe Passoni; Uppsala universitet; []
   Nyckelord :Wave energy; permanent magnets; linear generator; closed stator slots; offshore experiments;

   Sammanfattning : The thesis presents results from synchronous linear wave energy converters developed at Uppsala University. A study is done on closed stator slots and a study presenting offshore data focusing on the power absorption from a wave energy converter (WEC). LÄS MER

7. 10. Radiant Textiles : A framework for designing with electromagnetic phenomena

   Författare :Erin Lewis; Delia Dumitrescu; Katharina Bredies; Högskolan i Borås; []
   Nyckelord :HUMANIORA; HUMANITIES; smart textiles; interaction design; textile interaction; textile; electronic; electromagnetism electromagnetic; design methods; artistic research; Textiles and Fashion Design ; Textil och mode konstnärlig ;

   Sammanfattning : The design of smart, interactive, computational, and electronic textiles involves working with unknown variables that expand the tangible dimensions of textiles. Non-visual concepts such as electromagnetic fields, electrical current, computational code, and the temporal attributes of materials that exhibit dynamic qualities require that textile designers be able to perceive and manipulate domains of the textile that extend beyond its conventional forms of expression.
