  1. 1. Coupled waves as a model to describe chaotic turbulence pumped by radio waves in the ionosphere

    University essay from Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenUppsala universitet/Institutionen för fysik och astronomi

    Author : Axel Hahlin; [2018]
    Keywords : turbulence; coupled waves; plasma;

    Abstract : Experimental results concerning plasma turbulence pumped in theionosphere by powerful radio waves suggest that the turbulence is due todeterministic chaos. To investigate the possibility of deterministic chaosin the ionosphere coupled wave systems have been studied to see chaoticdynamics. READ MORE

  2. 2. Diffusion MRI of Brain Tissue: Importance of Axonal Trajectory

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

    Author : Jan Brabec; [2018]
    Keywords : dMRI; diffusion magnetic resonance; axonal trajectory; axonal geometry; undulations; modeling; axons; inverse problem; diffusion spectrum; time-dependent diffusion; Physics and Astronomy;

    Abstract : Obtaining microstructural information non-invasively on brain tissue remains a challenge. Diffusion magnetic resonance imaging (dMRI) is an imaging method that can provide such information. That includes geometrical considerations of nerve cells projections, axons, that are present in the white matter of the human brain. READ MORE

  3. 3. Coastal erosion in the region of Thu Bon River mouth, Vietnam

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Eric Asplund; Hanna Malmström; [2018]
    Keywords : Coastal erosion; Cua Dai Beach; longshore sediment transport; EBED; Cascade; Technology and Engineering;

    Abstract : Coastal erosion has increased worldwide during the last decades, mostly due to human activities. Vietnam is not spared, where many places within the country suffer from beach erosion. This report focuses on the region around Thu Bon river mouth in the central part of Vietnam. READ MORE

  4. 4. Statistical and machine learning methods for classification of episodic memory

    University essay from Lunds universitet/Matematisk statistik

    Author : Damir Basic Knezevic; Albin Heimerson; [2018]
    Keywords : Mathematics and Statistics;

    Abstract : Multiple modern methods of statistical feature extraction and machine learning are applied to classification of encoding and retrieval of episodic memories us- ing electroencephalogram (EEG) recordings. Raw data, different time-frequency methods, and multiclass common spatial patterns are used for statistical feature ex- traction. READ MORE

  5. 5. Investigating the properties of Planck's radiation law through theoretical and numerical studies

    University essay from Uppsala universitet/Tillämpad kärnfysik; Uppsala universitet/Tillämpad kärnfysik

    Author : Alice Graf Brolund; Rebecca Persson; [2018]
    Keywords : Planck; Wien; Maxwell-Boltzmann; Monte Carlo; stochastic; distribution; python; black body; radiation; jacobian; cavity radiation; stokastisk; numerisk; fördelning; svart kropp; strålning; svartkroppsstrålning; hålrumsstrålning;

    Abstract : A black body is an ideal object that absorbs all incident electromagnetic radiation and simultaneously emits radiation that only depends on the temperature. The radiation is described by Planck's radiation law and its maximum by Wien's displacement law. READ MORE
