  1. 31. Iterative Road Grade Estimation for Heavy Duty Vehicle Control

    Författare :Per Sahlholm; Karl Henrik Johansson; Jonas Sjöberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road grade; estimation; heavy duty vehicle; Kalman filter; automatic control; Automatic control; Reglerteknik;

    Sammanfattning : This thesis presents a new method for iterative road grade estimation based on sensors that are commonplace in modern heavy duty vehicles. Estimates from multiple passes of the same road segment are merged together to form a road grade map, that is improved each time the vehicle revisits an already traveled route. LÄS MER

  3. 32. Correlation effects in ionic perovskite crystals

    Författare :Konstantinos Papadopoulos; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; muon spectroscopy; ion dynamics; correlated systems; multifunctional materials; spintronics; perovskites; magnetic order; solar cells;

    Sammanfattning : Perovskites are a large family of versatile materials with favourable properties for spintronics and optoelectronics applications. The mineral CaTiO3 defines the archetypal crystal structure of perovskite materials with a general composition ABX3. LÄS MER

  4. 33. Molecular genetics of type 2 diabetes

    Författare :Li Luosheng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Type 2 diabetes; the Goto-Kakizaki rat; linkage analysis; quantitative trait locus; gene-gene interaction; high fat diet; disease progression; alternative splicing; comparative genomics.;

    Sammanfattning : Type 2 diabetes is a common and chronic disease caused by interactions between genetic and environmental factors. The Goto-Kakizaki (GK) rat is a well-established genetic model of type 2 diabetes. LÄS MER

  5. 34. Spatially Coupled Turbo-Like Codes

    Författare :Saeedeh Moloudi; Kommunikationsteknologi; []
    Nyckelord :;

    Sammanfattning : The focus of this thesis is on proposing and analyzing a powerful class of codes on graphs---with trellis constraints---that can simultaneously approach capacity and achieve very low error floor. In particular, we propose the concept of spatial coupling for turbo-like code (SC-TC) ensembles and investigate the impact of coupling on the performance of these codes. LÄS MER

  7. 35. Cut isogeometric methods on trimmed multipatch surfaces

    Författare :Tobias Jonsson; Mats G. Larson; Karl Larsson; Johan Hoffman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cut finite element method; isogeometric analysis; Nitsche s method; a priori error estimation; parametric geometry; interface problem; surface CAD;

    Sammanfattning : Partial differential equations (PDE) on surfaces appear in a variety of applications, such as image processing, modeling of lubrication, fluid flows, diffusion, and transport of surfactants.  In some applications, surfaces are drawn and modeled by using CAD software, giving a very precise patchwise parametric description of the surface.
