  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. Shock absorber dynamics : A parameter study of damper physical quantitiesand their effect on automobile comfort and control

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : David Stridfeldt; Jonsson Gustav; [2023]
    Keywords : Shock absorbers; dampers; parameter study; valve dynamics; comfort; control; Stötdämpare; dämpare; parameterstudie; ventildynamik; komfort; kontroll;

    Abstract :   Damper performance is most commonly characterized by the damper’s forcevelocity behaviour. Different damper layouts and valving methods for creating oil flow constrictions bring different physical properties, outside of this conventional measure. READ MORE

  4. 3. Human and Robot Narrator: How Gestures Affect Comprehension and Recollection

    University essay from Lunds universitet/Kognitionsvetenskap

    Author : Johannes Rosenfrost; [2023]
    Keywords : Cognitive Science; Cognition; Embodiment; Humanoid Robots; Social Robots; HRI; Human-Robot-Interaction; Social Interaction; Robotics; Linguistics; Communication; Multimodality; Non-verbal; Gestures; Narration; Comprehension; Recollection; Social Sciences;

    Abstract : This thesis investigated if a human or a robot narrator affected listeners’ comprehension and memory recollection similarly in a narrative story. 103 participants (MeanAge = 35) were recruited to an online experiment to investigate if gestures affected the participants’ narrative comprehension and recollection more than a narrator that did not produce gestures.

  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. Novel steel hinge connection for pedestrian timber bridges : Novel steel hinge connection for pedestrian timber bridges

    University essay from KTH/Byggnadsmaterial

    Author : Charlotte Jaeger; [2023]
    Keywords : ;

    Abstract : This study focuses on exploring a novel timber-to-timber joint using a steel hinge connection (in this work also referred to as door-hinge joint) for pedestrian timber bridges. To conduct the cross-section design of the structural bridge members, a numerical model was developed to determine the internal forces. READ MORE
