  1. 1. Buffer optimisation for an improved cell separation using Acoustophoresis with Polystyrene particles, Jurkat, MCF-7 and DU-145 cell lines

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Lovisa Silversand; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Akustophores är rörelse av partiklar/celler under inverkan av ljud. Partikel- och cell separation är en applikation som kan utföras av akustophores. Detta är en viktig teknik eftersom den kan avslöja viktig information om sjukdomar och celler och därigenom förbättra valet av behandling inom sjukvården. LÄS MER

  3. 2. Applicerbarhet av Scaled Reassigned Spectrogram for Transient Signals (ReSTS) på ultraljudssignaler från biologisk vävnad

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Sara Florentsson; Anna Hollsten; [2022]
    Nyckelord :Ultrasound; resolution; biological tissue; signal processing; Technology and Engineering;

    Sammanfattning : The possibility of being able to examine the inside of the human body is the foundation of today’s medical diagnostics. This can be done through different imaging systems, where ultrasound is one of the most important imaging methods used. LÄS MER

  4. 3. Improving bright-field images for tracking particles with Defocustracker

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Carl Lundin; [2022]
    Nyckelord :Defocustracker; GDPT; particle tracking; bright-field; acoustophoresis; Laplacian of Gaussian; Technology and Engineering;

    Sammanfattning : Acoustophoresis is a cell separation technology where particles or cells are suspended in a fluid container and subject to acoustic standing waves. The standing waves exerts an acoustic radiation force on the particles, pushing them towards the nodal plane. LÄS MER

  5. 4. Design of Autonomous Underwater Vehicle’s (AUV) Antenna System

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Chengzhuang Zhou; [2021]
    Nyckelord :AUV Antenna; Printed Dipole Antenna; Broadband Antenna; AUV antenna; Printed dipole antenna; Broadband antenna;

    Sammanfattning : The ocean symbolizes mystery, passion, and power. However, most of the ocean, about 80 %, is unknown to humans. AUVs (Autonomous Underwater Vehicles) provide a platform where terrain mapping, the biodiversity, and the resource survey of the ocean become accessible. LÄS MER

  7. 5. Towards Underwater UV Communication- Simulation and Experimentation on Penetration of UV Radiation into Sea water.

    Master-uppsats, Blekinge Tekniska Högskola

    Författare :Subhash Chandra Ranga; [2021]
    Nyckelord :Optical Communication; Underwater communication Underwater communication Optical communication; Underwater communication Acoustic communication; Underwater communication Microwave communication; Visible Light Communication; Refractive Index.;

    Sammanfattning : People around the globe are immensely trying to connect using light as carrier due to its low power consumption and high data transfer rates. Sound and microwaves are examples of other carriers that can be used, although they aren't nearly as efficient as light. A method of communicating is using light beneath the surface of the water.
