  2. 1. A search for leptoquarks with the ATLAS detector and hardware tracking at the High-Luminosity LHC

    Author : Mikael Mårtensson; Richard Brenner; Anders Ryd; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Leptoquarks; Hough transform; LHC; ATLAS; HL-LHC; Particle physics; Particle tracking; Cluster finding; Trigger; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : This thesis presents a search for pair-production of scalar leptoquarks, decaying into third-generation particles, using proton-proton collisions delivered by the Large Hadron Collider (LHC) and recorded by the ATLAS detector. It also presents the development of a hardware track trigger for the Phase-II upgrade of the ATLAS experiment. READ MORE

  4. 2. Feature extraction based on a tensor image description

    Author : Carl-Fredrik Westin; Linköpings universitet; []
    Keywords : Image analysis; Representation; Tensor; Hough transform; Möbius strip; Corner detection; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Feature extraction from a tensor based local image representation introduced by Knutsson in [37] is discussed. The tensor representation keeps statements of structure, certainty of statement and energy separate. READ MORE

  5. 3. Diagnostic Methods for Composite Insulators with Biological Growth

    Author : Andreas Dernfalk; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; algae; composite insulators; Hough transform; biological contamination; outdoor insulation; digital image analysis; laser-induced fluorescence LIF ; fungi; diagnostic methods;

    Abstract : Composite insulators have a number of advantages compared to conventional insulators, but the fact that they are more prone to aging is a major drawback. For instance, biological growths, like algae and fungi, have been found to colonize composite insulators, and possibly effecting the insulation performance. READ MORE

  6. 4. On robot control with feedback from optronic sensors

    Author : Ulf Larsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : The problem studied in this thesis is control of robots using information from optronic sensors. With a laser range sensor onboard the robot the relative distance to an object can be measured. This allows the robot to operate in a partial unknown environment. One complication with non-contact sensors is the assiciation problem, i. READ MORE

  7. 5. Solving the correspondence problem in analytical chemistry : Automated methods for alignment and quantification of multiple signals

    Author : Erik Alm; Magnus Åberg; Beata Walczak; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Abstract : When applying statistical data analysis techniques to analytical chemical data, all variables must have correspondence over the samples dimension in order for the analysis to generate meaningful results. Peak shifts in NMR and chromatography destroys that correspondence and creates data matrices that have to be aligned before analysis. READ MORE
