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. Analys av ljudabsorberande spaltpaneler med varierande spjälbredd : En studie med mål att tillförse mätdata samt analysera stående våg över spjälbredd

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

   Författare :Johan Wangärd; Arthur Öhman; [2023]
   Nyckelord :Akustik; Spaltpanel; Membranabsorbent; Ljudabsorption; Helmholtzresonans;

   Sammanfattning : This study is based on a hypothesis from Delta Akustik AB regarding standing waves in slotted panels and the requisite for measurement data regarding its sound absorption. The purpose is to acquire measurement data and to examine three types of slotted panels and the possibility of a standing wave vertically in the boards. LÄS MER

4. 3. Buffer modification: A case study with polystyrene beads, DU145-, and MCF7 cell lines

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Olivia Hansson Rengbrandt; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Separation of cancer cells gives advantages in understanding the disease, guiding treatment decisions, and facilitating drug development. Overall, separation plays an important role in biological research. Acoustophoresis is a technique that utilizes acoustic waves to separate particles and cells suspended in a buffer medium. LÄS MER

5. 4. General Defocus Particle Tracking

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Joakim Anderberg; [2023]
   Nyckelord :General Defocus Particle Tracking; ultrasonic standing waves; microscopy; microchip; single plane particle tracking; levitation; Generel ur-fokus partikel spårning; stående ultraljudsvågor; mikroskopi; mikorchip; enkelplans partikel spårning; levitation;

   Sammanfattning : Three-dimensional particle tracking is a valuable tool in microfluidics for obtaining information about a system. General Defocus Particle Tracking (GDPT) is a straightforward method of 3D particle tracking that only requires a single-camera plane, making it applicable to existing equipment in a laboratory.

7. 5. Streamline the ski rental process using RFID technology : Develop a solution that optimizes the ski rental process and is designed after the customer´s and staff´s needs.

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Författare :Hanna Lundgren; [2022]
   Nyckelord :Ski rental; Streamline; RFID technology; Human-centred design; Service design; Industrial design engineering; Skiduthyrning; Effektivisering; RFID; Användarcentrerad design; Service design; Teknisk design;

   Sammanfattning : Imagine you have booked a trip to the mountains and want to experience nature and the slopes. But unfortunately, you do not own your equipment and need to rent from a ski rental. As a customer, you then hope the rental process goes quickly, smoothly, and efficiently to avoid standing in long queues. LÄS MER
