  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. Simulation of a Rotational Brake System Regulated by Change in Angular Deceleration

    University essay from Lunds universitet/Mekanik

    Author : Dennis Stenson; Marko Sarajärvi; [2019]
    Keywords : Technology and Engineering;

    Abstract : A fully mechanical rotational brake system activated and regulated by rate of change in angular velocity has been developed by Brillianze Sweden AB. Its field of usage is currently limited and is to be expanded upon. Therefore new models were made to perform multibody dynamics simulations in Adams/View. READ MORE

  3. 3. Individualized Contractile Ankle Joint Muscular Properties in Healthy and Post-Stroke Subjects

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Hoor Jalo; [2019]
    Keywords : ;

    Abstract : This study investigated the contractile properties of the plantar-and dorsi-flexor muscles controlling the ankle joint. The purpose of this study was to investigate how the muscle strength and muscle architecture change after stroke, and how the muscle strength and architecture are correlated. READ MORE

  4. 4. Reconstruction of Fall Injuries for Children of Different Ages

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Linda Björgvinsdóttir; [2019]
    Keywords : Medical Engineering; Biomechanics; Neuronics; Reconstruction; Falls; Children; LS-Dyna; LS-PrePost; PIPER;

    Abstract : The idea to use finite element (FE) models to reconstruct accidents for humans is becoming more popular the last years. They represent the human body very accurately and indicate well changes in shape, size and biomechanical properties. READ MORE

  5. 5. Evaluation of Test Methods for Football Helmets Using Finite Element Simulations

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Aðalheiður Gunnarsdóttir; [2019]
    Keywords : Concussion; Football Helmets; Test methods; FE simulations;

    Abstract : Introduction: Concussions in American Football are of a major concern due to highly reported injury rates. The importance of properly designed helmets have shown effect in reducing the risk of injuries, such as skull fractures. However, they are not as effective in reducing the risk of concussion.
