  1. 1. Optimisation of the gas atomisation process used in aluminium powder production : To improve morphology by minimising satellite formations

    University essay from KTH/Materialvetenskap

    Author : Henrik Hedlin; Johan Nymo; [2023]
    Keywords : ;

    Abstract : There exists a lack of information and an exact understanding of the gas atomisation process resulting in the use of trial and error methods in the industry. The lack of information is the result of the difficulties in observing the actual process as it occurs, something that the use of computational fluid dynamics may be able to substitute. READ MORE

  3. 2. The Semantics of the Recorded Drum Kit and its Processing

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Alexander Evans; [2023]
    Keywords : Semantics; drums; drum kit; rock n roll; rock music; rock drums; snare; cymbal; kick; hi-hat; music semantics; audio semantics; communicative audio; semantik; trummor; hårdrock; musiksemantik; virvel; bastrumma; cymbal; musikalisk kommunikation;

    Abstract : This study investigated the terms used by drummers and audio engineers to describe the recorded drum kit and the processing applied to it. The main method consisted of semi-structured interviews with six professionals in the fields of drumming and audio engineering. READ MORE

  4. 3. NH Planetary-Scale Circulation in Troposphere and Stratosphere: A Spectral and Dynamical Perspective

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Michael Konrad Schutte; [2023]
    Keywords : jet stream; Rossby waves; polar vortex; spectral analysis; dynamic systems theory; sudden stratospheric warmings; strong polar vortex events; jetström; Rossbyvågor; polär virvel; spektralanalys; dynamisk systemteori; plötsliga stratosfäriska uppvärmingar; starka polvortexhändelser;

    Abstract : Dynamic Systems Theory (DST) and spectral analysis are employed to study the tropospheric jet stream and the stratospheric polar vortex. The objective is to investigate the relationship between Rossby wave activity and inverse persistence and dimensionality of geopotential height at 250 hPa and 10 hPa, as these two dynamical indicators are expected to show a characteristic behavior of Rossby wave harmonics.

  5. 4. Association analyses of forehead hair whorls, behaviour, and chromosome regions in Standardbred Trotters

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Victoria Saxe; [2022]
    Keywords : behaviour; temperament trait; tricoglyph; hair whorl; swirl; genetics; horse; Standardbred trotter; genotype; phenotype;

    Abstract : Introduction: In horse breeding, athletic skills have been in focus and certain behaviour types have been found to be important for competition. Behaviour is heritable but is also affected by the environment. Just like humans, animals have their own personality and behaviour-traits. READ MORE

  6. 5. Study of tip clearance flows

    University essay from KTH/Flygdynamik

    Author : Camille Fournis; [2018]
    Keywords : turbomachine; compressor; tip leakage flow; vortex; turbomaskin; kompressor; gapflöde; virvel;

    Abstract : The tip leakage vortex is responsible for the generation of stagnation pressure losses inside the compressor along with the outbreak of rotating stall and surge. The current paper analytically proved that a part of the losses is proportional to the vortex circulation squared. READ MORE
