  3. 17. Humanoid Arm Geometric Model

    University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Author : Sebe Stanley Mulumbwa; [2016]
    Keywords : 7 DOF Humanoid Arm; Singularities; Singular value Filtering; Selectively Damped Least Squares; Euler Angle Switching; Obstacle Avoidance; Joint Limit Avoidance;

    Abstract : The world is slowly moving into increased human-robot interaction where both humans and robots can co-exist in the same domain. For the robot to be able to operate effectively in a man’s designed environment, it becomes necessary to model the robot with human capabilities as humans are seen as more capable. READ MORE

  4. 18. A Comparison of Rotation Parameterisations for Bundle Adjustment

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Nuerrennisahan Aimaiti; [2015]
    Keywords : ;

    Abstract : Bundle Adjustment is an iterative process where 3D information is estimated from 2D image measurements. Typically, the position of object points are estimated simultaneously with the position and orientation of the cameras. READ MORE

  6. 20. Non-isotropic Cosmology in 1+3-formalism

    University essay from Linköpings universitet/Matematiska institutionen; Linköpings universitet/Tekniska högskolan

    Author : Johan Jönsson; [2014]
    Keywords : Non-isotropic cosmology; Einstein; Relativity; Bianchi Type I; 1 3-covariant formalism;

    Abstract : Cosmology is an attempt to mathematically describe the behaviour of the universe, the most commonly used models are the Friedmann-Lemaître-Robertson-Walker solutions. These models seem to be accurate for an old universe, which is homogeneous with low anisotropy. READ MORE
