  1. 1. Non-destructive Evaluation of Ultrasound Contrast Agent

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Wendi Löffler; [2019]
    Keywords : ultrasound; microbubbles; contrast agent; attenuation; phase velocity;

    Abstract : Clinical ultrasound imaging techniques can be greatly improved by the use of ultrasound contrast agents (UCAs). While microbubbles (MBs) without shell are unstable and cannot be used for practical applications,a shell produced from biocompatible polyvinylalcohol (PVA) significantly improves chemical versatility and stability.

  2. 2. Beyond Vision: Eyeless Writing in Virginia Woolf's The Waves

    University essay from Stockholms universitet/Engelska institutionen

    Author : Marie-Helen Stahl; [2019]
    Keywords : Modernism; Virginia Woolf; Maurice Merleau-Ponty; phenomenology; vision; eyeless writing; anti-ocularcentrism; nonanthropocentrism; body;

    Abstract : In the early 20thcentury, a “crisis of ocularcentrism” arose in philosophy, replacing the Cartesian epistemological notion of a disembodied mind inspecting the object-world from the outside with an ontological and phenomenological approach to vision and being, embedding humans corporeally in a world exceeding their perceptual horizon (Jay 94). In response, modernist artists abandoned realist and naturalist techniques, rejecting mimetic representation, and experimented with new artistic forms, trying to account for the new complexity of life.

  3. 3. Pulse Repetition Interval Time Series Modeling for Radar Waves using Long Short-Term Memory Artificial Recurrent Neural Networks

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Adam Lindell; [2019]
    Keywords : ;

    Abstract : This project is a performance study of Long Short-Term Memory artificial neural networks in the context of a specific time series prediction problem consisting of radar pulse trains. The network is tested both in terms of accuracy on a regular time series but also on an incomplete time series where values have been removed in order to test its robustness/resistance to small errors.

  4. 4. Acousto-Electromagnetic Interaction in Materials for Aerospace Composites

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Niklas Wingren; [2019]
    Keywords : Non-destructive testing; Ultrasound; mm-waves; Photoelasticity; Multiphysics; Technology and Engineering;

    Abstract : Non-destructive testing (NDT) is a vital part of aerospace manufacturing due to high demands for quality and safety. Advances in materials science have given rise to aerospace composites with highly improved properties compared to traditional materials. READ MORE

  5. 5. Feasibility of an Electrically Tuneable EMC Susceptibility Antenna for 26-150 MHz

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

    Author : Lucas Svensson; Gustaf Ljungné; [2019]
    Keywords : EMC; tuneable; antenna; low frequency; susceptibility; electromagnetic compatibility; immunity; testing; 26-150 MHz; changing size; EZNEC; SAAB; tuned antenna; anechoic chamber;

    Abstract : Electromagnetic compatibility (EMC) is an essential part in today’s society and there are more products around us that emit electromagnetic waves than ever before. To make sure that all these products function properly under all circumstances EMC testing is needed. One test that is conducted is radiated immunity testing. READ MORE
