  2. 1. Light propagation in an anisotropically scattering medium

    Author : Elena Vasileva; Sergei Popov; Miguel A. Alonso; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anisotropic light scattering; scattering material characterization; polarization dependent scattering; diffusive media; hierarchical structure; biocomposites; wood modification; transparent wood; microfibrils angle; organic materials; polymer active devices; dye lasers; coherence; polarization; degree of polarization.; Fysik; Physics;

    Abstract : Scattering is the main phenomenon of light-matter interaction. In this thesis, we consider one specific case of light propagation in a material whose structure causes anisotropic optical scattering - transparent wood. READ MORE

  4. 2. Transition Radiation Tracker calibration, searches beyond the Standard Model and multiparticle correlations in ATLAS

    Author : Alejandro Alonso; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beyond Standard Model; ATLAS; LHC; Fourth family of quarks; Same-sign top production; Drift tubes; TRT; QCD; Supersymmetry; Inner Detector calibration; Tracking;

    Abstract : This thesis contains two different aspects of my research work towards physics in proton-proton collisions in the ATLAS experiment at the LHC. The first part is focused on the understanding and developing of a calibration system to obtain the best possible charged particle reconstruction in the Transition Radiation Tracker. READ MORE

  5. 3. Contributions to certain problems in algebraic topology

    Author : Juan M. Alonso; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Algebraisk topologi;

    Abstract : We consider two problems. The first one is to determine when a fibration is also a (homotopy) cofibration. We use a classic result of T. Ganea to give a complete algebraic solution. READ MORE

  6. 4. Faster and More Resource-Efficient Intent Classification

    Author : Pedro Alonso; Marcus Liwicki; Ali Basrat; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Maskininlärning; Machine Learning;

    Abstract : Intent classification is known to be a complex problem in Natural Language Processing (NLP) research. This problem represents one of the stepping stones to obtain machines that can understand our language. Several different models recently appeared to tackle the problem. The solution has become reachable with deep learning models. READ MORE

  7. 5. Models and Simulations of the Electric Field in Deep Brain Stimulation : Comparison of Lead Designs, Operating Modes and Tissue Conductivity

    Author : Fabiola Alonso; Karin Wårdell; Simone Hemm; Johannes D Johansson; Fernando Seoane; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Deep brain stimulation (DBS) is an established surgical therapy for movement disorders such as Parkinson’s disease (PD) and essential tremor (ET). A thin electrode is implanted in a predefined area of the brain with the use of stereotactic neurosurgery. READ MORE
