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

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Olivia Hansson Rengbrandt; [2023]
    Keywords : Technology and Engineering;

    Abstract : 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.

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

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

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

    Abstract : 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. READ MORE

  4. 3. A Platform for a Wheeler's Delayed-Choice Experiment in Optical Fiber

    University essay from Linköpings universitet/Informationskodning

    Author : Gustaf Åhlgren; [2022]
    Keywords : Wheeler s delayed choice; wave-particle delayed choice; Sagnac interferometer; Mach-Zehnder interferometer; complementarity relation;

    Abstract : Quantum mechanics has played a big role in the development of our understanding of the smallest things in the universe. It has provided descriptions for phenomena like single electrons or single photons, which are single particles of light. One of the most mysterious properties of quantum systems is the ability to behave as a particle or a wave. READ MORE

  5. 4. Development of a CFD Boundary Condition to Simulate a Perforated Surface

    University essay from Umeå universitet/Institutionen för fysik

    Author : Medet Kiflemariam; [2021]
    Keywords : Computational Fluid Dynamics; CFD; Boundary Condition; Bleed; Aerospace Engineering; Aeronautical Engineering; Physics;

    Abstract : In aircraft with jet propulsion engine intakes at supersonic speed, strong pressure waves referred to as shockwaves occur, which may interact with any present boundary layers along the intake surface. The adverse pressure gradients associated with Shock Wave-Boundary Layer Interaction (SWBLI) may cause boundary layer flow separation, which can result in disturbances of the flow that can be harmful to the device or decrease engine performance.

  6. 5. Protection of HVDC Grids Against Blackouts (Simulation)

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Amal Al-Ammari; Dinah Atchan; [2021]
    Keywords : High Voltage Direct Current HVDC ; Voltage derivative dv=dt algorithm; Traveling wave algorithm; PSCAD simulation; Multi-terminal grid; Fault detection; Threshold value; Offshore HVDC; DC breaker; Voltage collapse;

    Abstract : In the search for green energy to combat climatechange, a shift from conventional energy sources such as coal,oil, and nuclear towards Renewable Energy Sources (RES) isneeded. This shift poses a threat to the stability of the powergrids as RES do not contribute with rotating mass in the system. READ MORE
