  2. 1. Model-based Methods in Motion Capture

    Author : Kjartan Halvorsen; Antonie J. van den Bogert; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Systemteknik; Systemanalys; Systems Analysis;

    Abstract : This thesis concerns the use of kinematic models and shape models to solve the problem of estimating the motion of articulated objects from image data. The data considered in the first part of the thesis are trajectories of 3D feature points (markers). In the second part, image sequences are considered. READ MORE

  4. 2. Estimating Human Limb Motion Using Skin Texture and Particle Filtering

    Author : Björn Holmberg; Håkan Lanshammar; Virgil Stokes; Christopher L. Vaughan; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human motion analysis; Skin texture; Monte Carlo estimation; Particle filter; Mutual Information; Simulated Annealing; Marker-free; Rigid body transformation; 2D correlation; Systems engineering; Systemteknik;

    Abstract : Estimating human motion is the topic of this thesis. We are interested in accurately estimating the motion of a human body using only video images capturing the subject in motion. Video images from up to two cameras are considered.The first main topic of the thesis is to investigate a new type of input data. READ MORE

  5. 3. Single-Zone Cylinder Pressure Modeling and Estimation for Heat Release Analysis of SI Engines

    Author : Markus Klein; Lars Eriksson; Lars Nielsen; Per Tunstål; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heat release; parameter estimation; prior knowledge; regularization; specific heat ratio; compression ratio; Systems engineering; Systemteknik;

    Abstract : Cylinder pressure modeling and heat release analysis are today important and standard tools for engineers and researchers, when developing and tuning new engines. Being able to accurately model and extract information from the cylinder pressure is important for the interpretation and validity of the result. READ MORE

  6. 4. Quantifying human balance : Analysis of force plate data

    Author : Annica Önell; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Systemteknik; Systemanalys; Systems Analysis;

    Abstract : There is a lack of reliable methods for assessment of balance suited for routine use in clinical settings. The thesis focuses on analysis of force plate data for evaluation of balance during normal, unperturbed standing and sitting. Some commonly used force plate based methods during unperturbed standing are presented. READ MORE

  7. 5. Gaussian Random Numbers and Filtered GaussianNoise Wireless Channel models:A Hardware Perspective

    Author : Jamshaid Malik; Ahmed Hemani; Amir Alimohammad; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : This thesis comprises two distinctive but interrelated parts:1. Gaussian Random Number Generators (GRNGs)Gaussian Distributed Random Numbers (GRNs) are required for simu-lations in a wide variety of applications. READ MORE
