  1. 1. Test Equipment for the LUCAS Chest Compression System: Incorporating Biomechanical Insights for Future Design Enhancements

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Ester Pörtfors; Malin Svärdling; [2024]
    Keywords : Mechanical CPR; Cardiopulmonary Resuscitation; LUCAS Chest Compression System; Test Equipment; Chest Biomechanics; Chest Stiffness; Technology and Engineering;

    Abstract : The LUCAS Chest Compression System is a market leading mechanical cardiopulmonary resuscitation device, assisting medical professionals worldwide when treating patients with sudden cardiac arrest. The objective of this master thesis project was to develop a new, adjustable test equipment for the LUCAS device, allowing for tests on varying chest heights and stiffness levels. READ MORE

  3. 2. Time-based Key for Coverless Audio Steganography: A Proposed Behavioral Method to Increase Capacity

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : John Alanko Öberg; Carl Svensson; [2023]
    Keywords : Coverless audio steganography; information hiding; covert communication; effective capacity; behavioral; Täcklös ljudsteganografi; informationsdöljning; hemlig kommunikation; effektiv kapacitet; beteendemässig;

    Abstract : Background. Coverless steganography is a relatively unexplored area of steganography where the message is not embedded into a cover media. Instead the message is derived from one or several properties already existing in the carrier media. This renders steganalysis methods used for traditional steganography useless. READ MORE

  4. 3. Comparison between Smoothed-Particle Hydrodynamics and Position Based Dynamics for real-time water simulation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Rasmus Andersson; Erica Tjernell; [2023]
    Keywords : Fluid simulation; Lagrangian fluid simulation; Smoothed-Particle Hydronamics; Position Based Dynamics; Vätskesimulering; Lagransk vätskesimulering; Smoothed-Particle Hydronamics; Position Based Dynamics;

    Abstract : Two of the methods common in video game fluid simulation are SmoothedParticle Hydrodynamics (SPH), and Position Based Dynamics (PBD). They are both Lagrangian methods of fluid simulation. SPH has been used for many years in offline simulations and has truthful visuals, but is not as stable as the newer method PBD when using larger timesteps. READ MORE

  5. 4. Validation of Finite Element Model of a Tetra Pak Package

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Warsame Mohamed Ali; Abdullahi Abdi Hashi; [2023]
    Keywords : Abaqus; HDPE; Package testing; Validation; Abaqus; HDPE; Pakettestning; Validering;

    Abstract : There is a high dependency on accurate finite element models in the packaging industry for concept selection, design and virtual validation of packages. One of themost used materials for these packages is High-Density Polyethylene (HDPE). Thismaterial is highly anisotropic, strain rate dependent and has different behavior intension and compression.

  6. 5. 3D Knit fabrics : optimizing spacer knit fabrics for comfort and breathability in infant products

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Julia Svensson; Hanna Halldorf; [2023]
    Keywords : Spacer fabric; knitting; warp knit; circular knit; textile testing; ProCad Warpknit; infant product; comfort; mechanical properties.;

    Abstract : In this study we looked into an existing textile baby stroller seat and investigated whether there can be any advantage in changing the material to a spacer fabric from perspectives such as functionality, comfort, and sustainability. The subject of 3D knitting, and advanced knitting is being researched more and more because of its versatility in producing and changing parameters of knitted high quality products, but there is a lack of studies done on comfort for children when it comes to knitted spacer fabrics and not many studies have been done on spacer fabrics used for baby seats in strollers or other types of seats for children.
