  1. 1. Investigation of Injury Predictors for Rat Neuro Trauma

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Rosetta Maglio; [2024]
    Keywords : Finite element method; Rat brain traumatic brain injury; Rat brain finite element model; Strain; Strain rate; Product of strain and strain rate; Rotational direction; Rotational duration; Injury prediction; Finita elementmetoden; Råtthjärnans finita elementmodell; Belastning; Belastningshastighet; Produkten av belastning och belastningshastighet; Rotationsriktning; Rotationstid; Skadeförutsägelse;

    Abstract : A traumatic brain injury is usually caused by a direct impact to the head and is a common cause of disability and death all around the world. The most effective method to predict brain injury today, is to use a finite element head model. READ MORE

  3. 2. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Sara Falk; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. READ MORE

  4. 3. Requirements and Analysis of an Overload Protection Mechanism for an Electromechanical Linear Actuator

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Mats Vesterberg; [2022]
    Keywords : EMA; Electromechanical Actuator; Linear Actuator; Shock load; Protection mechanism; Elektromekaniska ställdon; Linjära ställdon; Shocklaster; Överlastskydd;

    Abstract : Cascade Drives specializes in high-performance electromechanical linear actuators (EMA). The company has developed a range of linear rack and pinion actuators based on a patented load distribution technique that allows multiple pinions to interact with a single gear rack. READ MORE

  5. 4. Asymmetries and Their Impact on Explosively Formed Projectiles Performance

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Kristoffer Seidel; [2021]
    Keywords : ;

    Abstract : Shaped Charges (SC) are explosives which are set up to concentrate the energy of an explosive to deform a thin metal cover, so called liner into either a jet of particles or a solid projectile, the latter one is refered to an Explosively Formed Projectile or EFP. The purpose of this project is to map out the effect of different asymmetries in different parts of the EFP. READ MORE

  6. 5. Hand Gesture Controlled Omnidirectional Vehicle

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : ANTON NORMELIUS; KARL BECKMAN; [2020]
    Keywords : Mechatronics; Mecanum Wheels; Hand Gesture Control; Arduino; Wireless; Mekatronik; Mecanumhjul; Handstyrning; Arduino; Trådlös;

    Abstract : The purpose of this project was to study how hand gesture control can be implemented on a vehicle that utilizes mecanum wheels in order to move in all directions. Furthermore, it was investigated how the steering of such a vehicle can be made wireless to increase mobility. A prototype vehicle consisting of four mecanum wheels was constructed. READ MORE
