  1. 11. Quality Control in Aluminium Profiles : Non-destructive Methods using Non-linear Ultrasonic

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Viktor Svensson; Robin Raymundsson; [2023]
    Keywords : Acoustic; defect; detection; harmonic; Akustisk; defekt; detektion; överton;

    Abstract : When aluminium profiles are manufactured, defects may arise, especially when theprofiles are manufactured through extrusion. During the extrusion process, thesedefects occur on parts of the extruded material because of contaminates that needto be found. READ MORE

  3. 12. Development of Reliability Test Rigs for Total Artificial Heart Pumps

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Alisa Besic; Martin Ogeborg; [2022]
    Keywords : Total Artificial Heart; TAH; Reliability testing; software; labview; CompactRIO;

    Abstract : The long-term performance of TAH pumps needs to be demonstrated. Reliability tests are performed to measure its ability to operate for months, or years, without failure. Real Heart is currently constructing test rigs for this purpose. Software for documenting test rig conditions is also required. READ MORE

  4. 13. Pushing the boundaries of acoustic particle separation: achieving high-throughput, avoiding spillover effects, investigating the effects of the particle concentration, and measuring acoustic properties

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Linda Péroux; [2022]
    Keywords : Technology and Engineering;

    Abstract : Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. READ MORE

  5. 14. Capacitive Micromachined Ultrasonic Transducers for Underwater Applications

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Patrick Johansson; [2021]
    Keywords : CMUT; capacitive; micromachined; ultrasonic; transducer; model;

    Abstract : Capacitive micromachined ultrasonic transducers (CMUT:s) are often used in medical imaging and they show some promise as underwater transducers. This thesis collates the available information about how CMUT:s operate, their strengths and weaknesses and investigates their efficiency as an underwater transducer. READ MORE

  6. 15. Design and Development of a Data Acquisition and Communication System for Point Absorber Tracking

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Balakrishnan Kannan; [2021]
    Keywords : Data Acquisition System; Raspberry Pi; Controller; Processor; Wave buoy; Lysekil; wave energy; measurements; IMU; GPS; Strain gauge; force; Solar energy; Battery; communication; 4G; internet; Remote tracking; Shell; Python;

    Abstract : The recent trend in generating energy from the waves has led to several advancements in the methods and the various research is conducted across the world, to study the behaviour of point absorbers on the waves. The point absorbers such as wave buoys are designed to move according to the waves and the generator that is mechanically coupled with the buoys, generate electricity. READ MORE
