  1. 1. General Defocus Particle Tracking

    University essay from KTH/Tillämpad fysik

    Author : Joakim Anderberg; [2023]
    Keywords : 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;

    Abstract : 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.

  3. 2. Bearing condition monitoring : An investigation on the possibility of monitoring aging of the lubricating grease by means of acoustic emission and temperature.

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Dilesh Raj Shrestha; [2021]
    Keywords : Acoustic Emission; Fourier Transform; Infrared Spectroscopy; Condition Monitoring; Total Acidic Number; Fast Fourier Transform; Scanning Electron Microscopy; Rheology; Bleed Oil; Grease degradation;

    Abstract : Grease is among the most widely used lubricants in rolling element bearings. Proper understanding of the effect of lubrication due to grease aging can provide a significant increase in the life of the engineering systems. However, at present, there is no sufficient understanding of the grease aging effect in rolling elements bearing. READ MORE

  4. 3. Ultrafast Transient coherent Raman Microscopy(TRaM)

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Eric Nilsson; [2019]
    Keywords : Physics and Astronomy;

    Abstract : The aim of this project was to construct a measurement setup to be able to measure the decoherence time of optical phonons. Optical phonons lose coherence by decaying to intermediate phonons and eventually to acoustic phonons which can carry heat, which is why measuring the coherence time of optical phonons is important to characterizing heat flow on short time scales.

  5. 4. Evaluation of dry fly-ash particles causing difficult deposits for acoustic soot blowing of boilers

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Arvid Cedervall; [2016]
    Keywords : ash; blowing; boiler; density; deposit; dry; fouling; infrasound; particles; soot;

    Abstract : This thesis compares ash collected from different boilers cleaned using infrasound cleaning. The samples were evaluated from their physical properties, in an attempt to find connections between the difficulty to remove ash and its physical appearance. READ MORE

  6. 5. Novel micromechanical bulk acoustic wave resonator sensing concepts for advanced atomic force microscopy

    University essay from KTH/Mikro- och nanosystemteknik

    Author : Stefan Wagner; [2012]
    Keywords : ;

    Abstract : This thesis investigates novel concepts of micromechanical bulk acoustic wave sensors for advanced atomic force microscopy (AFM), using micromachined silicon resonators, which are analyzed with regard to their performance as compared to conventional AFM sensors. Conventional AFM systems use a cantilever resonator for sensing the surface forces of the sample. READ MORE
