  1. 16. Branching Avoidance in Kinematic Image Space for Linkage Synthesis

    University essay from Lunds universitet/Matematik LTH

    Author : Adam Nilsson; [2013]
    Keywords : Linkage Synthesis; Quaternion; Dual Quaternion; Constraint Manifold; Four-Bar Linkage; Technology and Engineering; Mathematics and Statistics;

    Abstract : We consider a finite position synthesis and branching avoidance of four-bar linkages based on kinematic theory derived from dual quaternions. The branching defect is defined as a situation where all specified task positions are not connected by a continuous motion of the linkage end effector. READ MORE

  3. 17. Hydrodynamic Analysis and Simulation of a Tidal Energy Converter

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Marcus Jansson; [2013]
    Keywords : Motion Simulation Development; Tidal Energy; Energy Converter; Flight Dynamics; Quaternions; MATLAB; Simulink; Technology and Engineering;

    Abstract : A new motion simulator has been developed to simulate Minesto AB’s tidal energy converter flying in water. The motion simulator is as a part of a new computer based development environment, aiming to shorten the company’s development process. READ MORE

  4. 18. Quaternions Algebra, Their applications in Rotations and Beyond Quaternions

    University essay from Linnéuniversitetet/Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Gökmen GÜNAŞTI; [2012]
    Keywords : ;

    Abstract : The theory of quaternions was discovered in the middle of nineteenth century and they were commonly used to represent rotations.This thesis is written to review the basic properties of quaternions algebra and their applications in representing rotation of a body in 3-dimensional Euclidean space.

  5. 19. Intelligent Body Monitoring

    University essay from Reglerteknik

    Author : Rikard Norman; [2011]
    Keywords : quaternions; extended Kalman filter; human body movement; Euler angles; accelerometer; magnetometer; gyroscope; IMU; sensor fusion; kvaternjoner; olinjärt Kalmanfilter; mänsklig rörelse; Eulervinklar; accelerometer; magnetometer; gyro; gyroskop; IMU; sensorfusion;

    Abstract : The goal of this project was to make a shirt with three embedded IMU sensors (Inertial Measurement Unit) that can measure a person’s movements throughout an entire workday. This can provide information about a person’s daily routine movements and aid in finding activities which can lead to work-related injuries in order to prevent them. READ MORE

  6. 20. Estimation and Adaptive Smoothing of Camera Orientations for Video Stabilization and Rolling Shutter Correction

    University essay from Reglerteknik

    Author : Nicklas Forslöw; [2011]
    Keywords : camera orientation; video stabilization; rolling shutter; quaternions; EKF; EKFS; videostabilisering; rullande slutare;

    Abstract : Most mobile video-recording devices of today, e.g. cell phones and music players, make use of a Rolling Shutter camera. The camera captures video by recording every frame line-by-line from top to bottom leading to image distortion when either the target or camera is moving. READ MORE
