  2. 1. Methods for measurements and analyses of cracks in flexible pavements

    Author : Petra Offrell; KTH; []
    Keywords : Cracking; Crack propagation; Data collection methods; Image analysis; Image processing; LTPP; Automatic identification systems; Flexible pavement; PAVUE; Laser RST; measures; characterisation; x-ray computerised tomography; asphalt; 3D analysis; top-;

    Abstract : When cracking has propagated through the entire asphaltbound layers, water may ingress into the unbound layers andaccelerate the deterioration of the road structure. Knowledgeon where cracks initiate and how they propagate vertically istherefore of great practical importance. READ MORE

  4. 2. A Bayesian approach to retrospective detection of change-points in road surface measurements

    Author : Fridtjof Thomas; Urban Hjort; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Change-point detection; retrospective view; autoregressive processes; minimal imaginary training sample; road surface measurements; international roughness index; rutting; Laser-RST vehicles; road maintenance; pavement management; statistik; Statistics;

    Abstract : First-order autoregressive processes are analysed for sudden changes in parameter value. In its most general form, a multivariate vector of measurements is allowed, and no prior knowledge about the involved parameters is required. READ MORE

  5. 3. Photonic devices with MQW active material and waveguide gratings : modelling and characterisation

    Author : Nadeem Akram; Lars Thylén; Hartmut Hillmer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Method of Lines; Grating; ARROW Waveguide; Semiconductor laser; quantum well; Photonics; Fotonik;

    Abstract : The research work presented in this thesis deals with modelling, design and characterisation of passive and active optical waveguide devices. The rst part of the thesis is related to algorithm development and numerical modelling of planar optical waveguides and gratings using the Method of Lines (MoL). READ MORE

  6. 4. Combining the tactile resonance method and Raman spectroscopy for tissue characterization towards prostate cancer detection

    Author : Stefan Candefjord; Tomas Jansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Engineering for Healthcare; Medicinsk teknik för hälsovård;

    Abstract : Prostate cancer (PCa) is the most common male cancer in Europe and the US, and only lung and colorectal cancer have a higher mortality among European men. In Sweden, PCa is the most common cause of cancer-related death for men. READ MORE

  7. 5. Electron-nuclear Dynamics in Nonlinear Optics and X-ray spectroscopy

    Author : Sergey Polyutov; Faris Gelmukhanov; Patrick Norman; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Abstract : This thesis is devoted to theoretical studies of the role of nuclear vibrations on nonlinear and linear absorption, pulse propagation, and resonant scattering of light. The molecular parameters needed for the simulations are obtained through suitable quantum chemical calculations, which are compared with available experimental data. READ MORE
