  1. 6. High-speed stereo imaging for the characterization of anisotropic viscoelastic media

    Författare :Luca Manzari; Peter Göransson; Jacques Cuenca; Ines Lopez Arteaga; Mathieu Aucejo; KTH; []
    Nyckelord :Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : This thesis proposes an experimental method for observing and characterizing the viscoelastic properties of anisotropic media using high-speed white light stereo imaging. The method uses short-time video recordings of a specimen undergoing forced harmonic motion. LÄS MER

  3. 7. Towards Reliable and Accurate Global Structure-from-Motion

    Författare :José Pedro Lopes Iglesias; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bundle adjustment; point set registration; camera calibration; global SfM; Structure-from-Motion; radial distortion; 3D reconstruction; non-rigid SfM; pOSE; matrix factorization;

    Sammanfattning : Reconstruction of objects or scenes from sparse point detections across multiple views is one of the most tackled problems in computer vision. Given the coordinates of 2D points tracked in multiple images, the problem consists of estimating the corresponding 3D points and cameras' calibrations (intrinsic and pose), and can be solved by minimizing reprojection errors using bundle adjustment.

  4. 8. Lithium formate EPR dosimetry for accurate measurements of absorbed dose in radiotherapy

    Författare :Emelie Adolfsson; Åsa Carlsson Tedgren; Eva Lund; Håkan Gustafsson; Sara Olsson; Gudrun Alm Carlsson; Peter Sharpe; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Lithium formate has shown to be a material with properties suitable for electron paramagnetic resonance (EPR) dosimetry, among them up to 7 times higher sensitivity compared to alanine, which is a well-established EPR detector material for dose determinations in radiotherapy.The aim of this thesis was to further investigate the properties of lithium formate and develop the dosimetry system towards applications in radiotherapy.

  5. 9. Aeroacoustic Characterization using Multiport Methods

    Författare :Andreas Holmberg; Hans Bodén; Mats Åbom; Susann Boij; Lars Enghardt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeroacoustics; Multiport; Experiments; Computational Aeroacoustics; Mixer Plate; T-junction.;

    Sammanfattning : Noise is a major environmental pollutant, which can inict physical and psychologicalinjury. An important noise contribution stems from aeroacousticsources, which are found in e.g., ventilation ducts, engine exhaust systems andairplane engines. LÄS MER

  7. 10. Dynamic Optimization for Agent-Based Systems and Inverse Optimal Control

    Författare :Yibei Li; Xiaoming Hu; Per Enqvist; Yishao Zhou; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inverse optimal control; formation control; differential game; credit scoring; Mathematics; Matematik;

    Sammanfattning : This dissertation is concerned with three problems within the field of optimization for agent--based systems. Firstly, the inverse optimal control problem is investigated for the single-agent system. Given a dynamic process, the goal is to recover the quadratic cost function from the observation of optimal control sequences. LÄS MER
