  1. 1. Peripheral Vision : Adaptive Optics and Psychophysics

    Författare :Robert Rosén; Peter Unsbo; Larry Thibos; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is about our peripheral vision. Peripheral vision is poor compared to central vision, due to both neural and optical factors. The optical factors include astigmatism, defocus and higher order aberrations consisting mainly of coma. Neurally, the density of ganglion cells decreases towards the periphery, which limits the sampling density. LÄS MER

  3. 2. Finite element methods for threads and plates with real-time applications

    Författare :Karl Larsson; Mats G. Larson; Peter Hansbo; Umeå universitet; []
    Nyckelord :finite element method; real-time simulation; absolute nodal continuous formulation; large deformation; corotation; adaptive resolution; Kirchhoff-Love plate; reconstruction; discontinuous Galerkin; a priori error estimation; Mathematics; matematik;

    Sammanfattning : Thin and slender structures are widely occurring both in nature and in human creations. Clever geometries of thin structures can produce strong constructions while using a minimal amount of material. LÄS MER

  4. 3. High resolution time-frequency representations

    Författare :Isabella Reinhold; Statistical Signal Processing Group; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; time-frequency analysis; non-stationary signals; multi-component signals; IF estimation; reassignment;

    Sammanfattning : Non-stationary signals are very common in nature, e.g. sound waves such as human speech, bird song and music. It is usually meaningful to describe a signal in terms of time and frequency. LÄS MER

  5. 4. Reframing and Resolving Conflict : Israeli-Palestinian Negotiations 1988-1998

    Författare :Karin Aggestam; Statsvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; conflict; Palestine; Political and administrative sciences; PLO; Israel; negotiations; peace process; Middle East; resolving; reframing; resolution; transformation; diplomacy; Statsvetenskap; förvaltningskunskap;

    Sammanfattning : The mutual recognition between Israel and the PLO in 1993 signalled a major shift in the Israeli-Palestinian conflict. This study examines, both theoretically and empirically, the basic question of how meaning of conflict may change and how conflict may be resolved. LÄS MER

  7. 5. Quality Assurance of Time Critical Data Using Adaptive Data Delivery Mechanisms in Smart Grids

    Författare :Yiming Wu; Lars Nordström; Chen-Ching Liu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time critical data quality; adaptive mechanisms; quality assurance; Smart Grid; information resiliency; data accuracy; end-to-end latency; cyber-security; substation automation; power system communication; Electrical Engineering; Elektro- och systemteknik; Industrial Information and Control Systems; Industriella informations- och styrsystem;

    Sammanfattning : Smart grids are proposed to integrate renewable energy and to improve the efficiency of power system operation. The challenges of integrating renewable energy are the inherent fluctuations of generation which are difficult to predict which may lead to challenges to the safe operation of power systems. LÄS MER
