2. 1. Fast Algorithms for Integral Equations and Least Squares Identification Problems

   Author : Stefan Ljung; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fast algorithms; Integral equations; Least squares; Identification;

   Abstract : This work is concerned with fast algorithms for integral equations and least squares identification problems.The presentation is divided into three parts. In the first part a fast algorithm for solving systems oflinear equations with a matrix that is alm ost Toeplitz is derived and applied to Fredholm integral equations with stationary kernels.

4. 2. Show me love : Emergent strategic communication practices and fan engagement within the popular music industry

   Author : Jessica Edlom; Karin Fast; Michael Karlsson; Lee Edwards; Karlstads universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; agility; audience engagement; branding; co-creation; communication management; engagement; fandom; liquid; music industry; participation; practice theory; strategic communication; structuration theory; Media and Communication Studies; Medie- och kommunikationsvetenskap;

   Abstract : This thesis studies how the music industry’s strategic communication practices interplay with and steer audience and fan engagement. Relationships with, and expectations on, “active”, “prosuming” or “co-creative” music audiences make it imperative for communication practitioners to produce engagement. READ MORE

5. 3. Fast neutron dosimetry : a study of basic dosimetric properties of fast-neutrons for external beam radiotherapy and problems associated with corrections of measured charged particle cross-sections

   Author : Jonas Söderberg; Lennart Lindborg; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Basic dosimetric properties of fast-neutron beams with energies ≤80 MeV were explored using Monte Carlo techniques. Elementary pencil-beam dose distributions taking into account transport of all relevant types of released charged particles (protons, deuterons, tritons, 3He and a particles) were calculated and used to derive several absorbed dose distributions.

6. 4. Compressed Sensing : Algorithms and Applications

   Author : Dennis Sundman; Mikael Skoglund; Magnus Jansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compressed sensing; greedy pursuits; subspace pursuit; orthogonal matching pursuit; power spectral density estimation; distributed compressed sensing;

   Abstract : The theoretical problem of finding the solution to an underdeterminedset of linear equations has for several years attracted considerable attentionin the literature. This problem has many practical applications.One example of such an application is compressed sensing (cs), whichhas the potential to revolutionize how we acquire and process signals. READ MORE

7. 5. Algorithms for Coherent Diffractive Imaging with X-ray Lasers

   Author : Benedikt J. Daurer; Filipe Maia; Tomas Ekeberg; Janos Hajdu; Richard Neutze; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray lasers; coherent diffractive imaging; algorithms; lensless imaging; flash diffractive imaging; flash X-ray imaging; aerosol injection; FEL; XFEL; CXI; CDI; FXI; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

   Abstract : Coherent diffractive imaging (CDI) has become a very popular technique over the past two decades. CDI is a "lensless" imaging method which replaces the objective lens of a conventional microscope by a computational image reconstruction procedure. READ MORE
