  1. 1. Gamma Knife treatment planning with new degrees of freedom

    University essay from KTH/Optimeringslära och systemteori

    Author : Emil Norell; [2019]
    Keywords : Stereotactic radiosurgery; Leksell Gamma Knife®; inverse planning; clustering; optimization; column generation; Stereotaktisk radiokirurgi; strålkniven; inversplanering; klustring; optimering; kolumn-generering;

    Abstract : The Leksell Gamma Knife® is an instrument designed for high precision treatment of tumours and lesions located in the brain and upper spine. Today, the radioactive cobalt-60 sources can only move linearly along the radiation unit, but the machine could be modified to include rotational motion as well. READ MORE

  2. 2. Modeling and control of engaging gears in gearboxes without synchromesh towards specific angles between gear and coupling sleeve

    University essay from Linköpings universitet/Fordonssystem

    Author : Martin Blomgren; [2019]
    Keywords : Gearbox; synchronization; unsynchronized; synchromesh;

    Abstract : When engaging a new gear in an automated manual transmission (AMT) the gear needs to be synchronized with the main shaft's angular velocity in the gearbox. This is so that the parts can be connected through a cog wheel and torque can be transferred. To synchronize the angular velocities, mechanical synchronization components can be used. READ MORE

  3. 3. Distance estimations by non-linear step length models using accelerometer sensor data from waist-worn smart-phones

    University essay from Lunds universitet/Matematisk statistik

    Author : Benjamin Drorsén; Daniel Strandberg; [2018]
    Keywords : Mathematics and Statistics;

    Abstract : This thesis examines the possibility of modelling trajectory and estimating distance during a walk using only a smart phone attached to the waist. Due to GPS not functioning indoors, a navigation system without the need of external communication could be the perfect complement for closed spaces. READ MORE

  4. 4. Re-examining the dynamics of the Milky Way with new distance estimates

    University essay from Lunds universitet/Astronomi

    Author : John Wimarsson; [2018]
    Keywords : Milky Way dynamics; Gaia; distance estimates; Physics and Astronomy;

    Abstract : The use of reliable distance estimates is key to derive accurate three-dimensional velocities of celestial objects. Systematic overestimation and large uncertainties in the distances will thus provide misleading information of an object's kinematics. READ MORE

  5. 5. Modeling, Analysis and Control of Underwater Vehicle SROV

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Olle Ferling; [2018]
    Keywords : Technology and Engineering;

    Abstract : A new type of Remotely Operated Vehicle (ROV) has been designed by Marin Mätteknik (MMT) in cooperation with Reach Subsea and Kystdesign AS; the Surveyor ROV. Although MMT is successfully using the SROV in day-to-day operations, no mathematical model describing the system has previously been derived. READ MORE
