1. 1. Characterization of Pressure and Velocity Fields in Acoustophoresis Using Particle Tracks

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Jonathan Karlsson; [2023]
   Nyckelord :Acoustofluidics; Acoustophoresis; Ultrasonic Standing Waves; Acoustic fields; Particle tracking; Bio marking; Akustofluidik; Akustofores; Stående Ultraljuds Vågor; Akustiska fält; Particle tracking; Bio-markering;

   Sammanfattning : This master’s thesis explores the possibility of calculating and using the pressure andvelocity fields responsible for acoustophoresis. The goal was to use simulated data,similar to two-dimensional particle tracks from a specific microfluidic platform, toestimate the force potential and solve the partial differential equation (PDE) thatgoverns the relationship between the force potential and the acoustic fields.

3. 2. Measuring Acoustic Mobility of Particles by Particle Tracking Velocimetry

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Alexander Edthofer; [2022]
   Nyckelord :acoustophoresis; microfluidics; polystyrene; cells; particle tracking velocimetry; Technology and Engineering;

   Sammanfattning : Acoustophoresis is a method to manipulate and move cells or particles suspended in a medium using acoustic waves. The speed of the acoustophoretic motion depends on the cells' acoustic mobility, i.e. their size, density and compressibility relative to the medium. 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. Thermal Acoustic Flow inside an Ultrasound Resonator

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Enrico Corato; [2020]
   Nyckelord :Microfluidics; Ultrasound; Acoustofluidics; Thermal gradient; Thermoacoustic; Technology and Engineering;

   Sammanfattning : This thesis aims at investigating the interaction between thermal gradients and acoustic fields in microfluidic devices. In the research branch of Acoustofluidics, which bridges together acoustics and fluid dynamics, inhomogeneity in the medium has gained great interest due to the novel physics behind and the potential in manipulating submicrometer particles.

7. 5. Design of an Algorithm for Aircraft Detection and Tracking with a Multi-coordinate VAUDEO System

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Författare :Efrén Andrés Estrella Terneux; [2014]
   Nyckelord :Acoustic Vector Sensor; Kalman Filter; Aircraft Tracking; Acoustic Eyes; Acoustic Particle Velocity; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

   Sammanfattning : The combination of a video camera with an acoustic vector sensor (AVS) opens new possibilities in environment awareness applications. The goal of this thesis is the design of an algorithm for detection and tracking of low-flying aircraft using a multi-coordinate VAUDEO system. LÄS MER
