  2. 1. Motion estimation for perceptual image sequence coding

    Author : Kenneth Andersson; Håkon Husøy; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Since the advent of television obtaining high perceived quality using a limited bandwidth has been an important issue. This thesis proposes new methods for exploitation of temporal and perceptual redundancy in image sequences to achieve lower coding rate and/or higher visual quality. READ MORE

  4. 2. Quality and motion estimation for image sequence coding

    Author : Kenneth Andersson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Since the advent of television obtaining high perceived quality using a limited bandwidth has been an important issue. This thesis proposes methods inspired and based on the human visual system for exploitation of temporal and perceptual redundancy in image sequences to achieve lower coding rate and/ or higher visual quality.

  5. 3. Validation of antibodies for tissue based immunoassays

    Author : Sandra Andersson; Anna Asplund; Fredrik Pontén; Kenneth Wester; Mike Taussig; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antibody validation; Conjugation; Estrogen receptor-beta; IHC; ISH; Lymphohematopoietic tissues; Proteomic; RNAseq; TMA; Transcriptomic; Patologi; Pathology;

    Abstract : In situ protein detection in human tissues using antibodies reveals the cellular protein localization, and affinity-based proteomic studies can help to discover proteins involved in the development of diseases. However, antibodies often suffer from cross-reactivity, and the lack of positive and negative tissue controls for uncharacterized proteins complicates the mapping of the proteome. READ MORE

  6. 4. Wear of piston rings in hydrostatic transmissions

    Author : Ulf Skytte af Sätra; Sören Andersson; Kenneth Holmberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; piston ring; surface roughness; texture; coating; wear; hydraulic motor; Construction engineering; Konstruktionsteknik; Mechanical engineering; Maskinteknik;

    Abstract : This study focuses on the wear of piston rings in a hydraulic radial piston motor. The piston ring has to satisfy increasing demands for reliability and longer service life. It has two contacting surfaces, the face and the flank, and operates under a boundary lubrication state. READ MORE

  7. 5. Essays on labor market dynamics

    Author : Altin Vejsiu; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

    Abstract : This thesis consists of five essays on labor market dynamics.Essay I examines job tenure in Sweden over the period from the late 1960s and up to the end of the century. We investigate job tenure over time and how it varies across different labor force categories. READ MORE
