  1. 1. Classification of Heart Views in Ultrasound Images

    University essay from Linköpings universitet/Datorseende

    Author : David Pop; [2020]
    Keywords : AI; deep learning; echocardiography; image classification;

    Abstract : In today’s society, we experience an increasing challenge to provide healthcare to everyone in need due to the increasing number of patients and the shortage of medical staff. Computers have contributed to mitigating this challenge by offloading the medical staff from some of the tasks. READ MORE

  2. 2. The possibilities of recycling wash water at Vidinge

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Julia Mauritzson; [2020]
    Keywords : reuse; treatment; fresh-cut; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Abstract : Water is a resource of importance and with drier weather around the world, including Swe-den, there is a risk of too low levels of water to satisfy for instance households, animals and industries in the future. Fresh-cut fruit and vegetable industries are water intense and almost all process water is used in the washing process. READ MORE

  3. 3. Development of a Method to Measure Residual Stresses in Cast Components with Complex Geometries

    University essay from KTH/Materialvetenskap

    Author : Yang Yang; [2020]
    Keywords : Residual Stresses; Cast Iron; Engine Components; XRD; Ultrasonic; Cutting;

    Abstract : Cast iron, taking the advantages of the advanced castability forming components of complex geometries and favorable mechanical properties, is employed in engine components in truck industries. Compacted graphite iron (CGI) integrates both merits of lamellar graphite iron (LGI) and spheroidal graphite iron (SGI) such as good machinability and high thermal conductivity from LGI, high ultimate tensile strength (UTS), good fatigue resistance, high elastic modulus, and high ductility from SGI, thus is now becoming a competitive alternative of traditional LGI in cylinder blocks and heads.

  4. 4. Micromachining of microfluidicsystems using a nanosecond laser : Process optimization and application

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Per Söderbäck; [2019]
    Keywords : Acoustophoresis; Acoustofluidics; Laser micromachining; Microfabrication; Particle manipulation; Ultrasound;

    Abstract : Microfluidics is a field of research that enables the manipulation of fluids in the submillimetre length scale. The technology allows the development of lab-on-a-chip devices, which are miniaturized systems for chemical and biological analysis. READ MORE

  5. 5. Simulation and Analysis of Ultrasonic Wave Propagation in Pre-stressed Screws

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Erik Andrén; [2019]
    Keywords : ;

    Abstract : The use of ultrasound to measure preload in screws and bolts has been studied quite frequently the last decades. The technique is based on establishing a relationship between preload and change in time of flight (TOF) for an ultrasonic pulse propagating back and forth through a screw. READ MORE
