  2. 16. Multidimensional inverse problems in imaging and identification using low-complexity models, optimal mass transport, and machine learning

    Author : Axel Ringh; Johan Karlsson; Rodolphe Sepulchre; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inverse problems; convex optimization; variational regularization; trigonometric moment problems; optimal mass transport; computed tomography; machine learning; analytic interpolation; delay systems; Inversa problem; konvex optimering; variationell regularisering; trigonometriska momentproblem; optimal masstransport; datortomografi; maskininlärning; analytisk interpolation; system med tidsfördröjning; Mathematics; Matematik;

    Abstract : This thesis, which mainly consists of six appended papers, primarily considers a number of inverse problems in imaging and system identification.In particular, the first two papers generalize results for the rational covariance extension problem from one to higher dimensions.

  4. 17. Prokaryotic Arsenic Resistance - Studies in Bacillus subtilis

    Author : Emil Aaltonen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ArsB; Bacillus subtilis; arsenic resistance; arsenate reduction; arsenite transport; gene regulation; arsenate; ArsR; arsenite; transmembrane topology; Acr3; ArsK;

    Abstract : Arsenic is a toxic metalloid which is found all over the globe. Due to its toxicity and wide abundance, all living organisms have evolved intrinsic arsenic resistance systems. In this study, three proteins that provide arsenic resistance in the Gram-positive bacterium Bacillus subtilis have been investigated. READ MORE

  5. 18. Airborne cognitive systems in search of an appropriate context: Studies of the introduction of new technology in aviation using a cognitive systems engineering approach

    Author : Örjan Goteman; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lufttransportteknik; Air transport technology; Safety; RNAV; Pilot; Automation Modes; HUD; Datalink; Cognition; Automation; Aviation;

    Abstract : Abstract Technology is always designed for an assumed user in an assumed context. In commercial aviation, these design assumptions are clearly spelt out in that both crew and equipment are certificated for a specific operation as stated in the aircraft flight manual. READ MORE

  6. 19. Momentum-space dynamics of runaway electrons in plasmas

    Author : Adam Stahl; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; synchrotron radiation; tokamak; critical electric field; non-linear collision operator; slide-away; runaway electrons; fusion-plasma physics;

    Abstract : Fast electrons in a plasma experience a friction force that decreases with increasing particle speed, and may therefore be continuously accelerated by sufficiently strong electric fields. These so-called runaway electrons may quickly reach relativistic speeds. READ MORE

  7. 20. A dispatch procedure for traffic control of a fleet of remote-controlled automatic LHDS in underground hard rock mines : modelling approach is based on simulation

    Author : Nikolaos Vagenas; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : A concept for automating Load-Haul-Dump (LHD) vehicles has stimulated considerable interest in the Swedish mining industry. In this concept, tramming and dumping operations of an LHD should be automatic. During loading, an operator from a control room fills the bucket of a vehicle via remote-control aided by a television system. READ MORE
