  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. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

    University essay from Umeå universitet/Institutionen för fysik

    Author : Franz Wikner; [2024]
    Keywords : Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

    Abstract : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

  4. 3. Do viscous flows slip?

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Björn Sjösvärd; [2023-12-21]
    Keywords : Mathematics; partial differential equations; multivectors; Hodge de-compositions; the Stokes equation; Hodge boun;

    Abstract : In this thesis, the Stokes equation is discussed and solved under different boundary conditions. The Stokes equation governs the flow of viscous liquids, for example honey or syrup. The first chapters in the thesis provides an introduction to multivector algebra and analysis, with the aim of presenting the concept of Hodge decompositions. READ MORE

  5. 4. Structural Analysis and Redesign of a L90 Front Axle Casing

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Erik Berra Widén; [2023]
    Keywords : FEM; Ansys Mechanical; Axle Casing; Volvo CE; Wheel Loader; Redesign;

    Abstract : This thesis was commissioned by Volvo Construction Equipment (Volvo CE) to redesign the front axle casing of their L90 wheel loader to be more in line with their larger wheel loaders. The current L90 front axle casing consists of two parts bolted together in the middle. READ MORE

  6. 5. MANGO - Generating 2D-Magnetic Field Maps From Normal-Conducting Magnets Of Experimental Areas

    University essay from KTH/Fysik

    Author : Ambre Visive; [2023]
    Keywords : Applied Physics; Particle Physics; MANGO; Magnetic Field Maps; Normal-Conducting Magnets; Finite-Element Modelling; Opera-2D; Git Repository; Python Package; Beam Lines; Experimental Areas; CERN; Tillämpad Fysik; Partikelfysik; MANGO; Magnetfältskartor; Normalkonduktiva Elektromagneter; Finit Elementmodellering; Opera-2D; Git Repository; Python Package; Partikelstrållinje; Experimentområden; CERN;

    Abstract : This thesis discusses the development of MANGO, a tool created to model normal-conducting magnets which were installed in the 1970s in the experimental areas at CERN, and store their analysis. MANGO formulates an answer to two problems faced by the physicists of the Beam Department when they model a beam line: first, how to produce new magnetic field maps and, second, how to easily access existing ones? It contains a multi-use package that offers an automated process to produce magnetic field maps from finite-element models of magnets. READ MORE
