  1. 1. Prediction of industrial machine failure by analysing anomalies

    University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Author : Md Abdur Rahman Akash; [2022]
    Keywords : ;

    Abstract : The sudden downtime and unplanned maintenance not only drastically increase the maintenance cost but also decreases the production capacity for the manufacturer industries. This is because the machines on these industries fail suddenly and totally stop the production as the machine should be fixed by maintenance before it can run again. READ MORE

  2. 2. Computational modelling of photosynthetic excitons coupled to a microcavity

    University essay from Lunds universitet/Institutionen för teoretisk fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Ilmari Turunen; [2022]
    Keywords : Cavity QED; LH2; Chlorophyll; Exciton; Polariton; Transition dipole moment; Absorbance; Physics and Astronomy; Chemistry; Biology and Life Sciences;

    Abstract : Cavity quantum electrodynamics (QED) is a theory that is used for describing the interaction between matter and cavity modes. Not until relatively recently, cavity QED has been extended to the study of photosynthetic light-harvesting complexes (LHCs). READ MORE

  3. 3. Nyköpings årum : ett gestaltningsförslag av ett stråk längs Nyköpingsån

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Johannes Karlsson; Christopher Mörk; [2022]
    Keywords : Årum; stråk; gestaltning; kulturhistoria; tillgänglighet; harmoni;

    Abstract : Arbetet syftar till att visa hur ett utsnitt av Nyköpings årum kan gestaltas för att skapa ett enhetligt och sammanhängande parkstråk längsmed Nyköpingsån, parkstråket ska både vara tillgängligt och upplevas som tryggt. Arbetet tar avstamp i Nyköpings kommuns Utvecklingsprogram för Årummet från 2015. READ MORE

  4. 4. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors

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

    Author : Lassi Linnala; [2022]
    Keywords : femtosecond THz radiation; ultrafast x-ray diffraction; pump-probe; longitudinal optical phonons; zincblende semiconductors; anharmonic decay; density functional perturbation theory; Physics and Astronomy;

    Abstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.

  5. 5. Quantum statistics of a three-level maser

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Andreas Evensen; [2022]
    Keywords : Maser; Laser; SSD-maser; Euler s method; Runge-Kutta method; Louvillian; Dissipator; Lindblad s master equation; Entropy; Thermodynamics; Coherent-state; Glauber-state; Python; Rabi-Oscillations; Occupation number of the photon mode; Density operator; Physics and Astronomy;

    Abstract : Lasers and masers have numerous uses in today’s society. Improving our understanding of the underlying physics and its application is thus of great importance. READ MORE
