1. 1. Implementation of Dyson equation to accelerate convergence in RS-LMTO-ASA code

   University essay from Uppsala universitet/Materialteori

   Author : Elis Uebel; Viktor Frilén; [2024]
   Keywords : Density functional theory; Dyson equation;

   Abstract : First-principle calculations is a key ingredient for us to understand, improve and design new materials. Density functional theory (DFT) [1] has proven to be a very powerful tool and a number of different versions exist depending on the problem at hand. READ MORE

3. 2. Oscillations in a complex sunspot: From theory to data

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Femke Kranenbarg; [2024]
   Keywords : ;

   Abstract : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

   Keywords : Biofuel cell; Blood; Energy Harvesting; Glucose; Power Density; Oxygen;

   Abstract : In the current pursuit of sustainable energy, biofuel cells are attracting considerable attention. Within biomedical engineering, the concept of harnessing energy from biological fluids, such as blood, holds significant promise, enabling both full autonomy and miniaturization. READ MORE

5. 4. The Impact of Global Warming on Wind Power Potential in the Greater Horn of Africa

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Bromwel Apondi; [2023-08-17]
   Keywords : Near-surface wind speed; the Greater Horn of Africa; ERA5; Wind power density; CORDEX-Africa;

   Abstract : The wind speed variability and wind power potential in the Greater Horn of Africa is analyzed in this study to fill a knowledge gap regarding if wind power can be used more as a source of energy for the region. This is investigated based on reanalysis data from ERA5, observed wind speeds, CORDEX-Africa regional climate models (RCMs) for future projections and a literature review. READ MORE

6. 5. Temperature Optimum for Biomass Production of two Species of Benthic Diatoms

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Vilmer Jansson; [2023-06-22]
   Keywords : ;

   Abstract : Diatoms and other algae can be cultivated and beneficially used in several sectors with applications ranging from nutrient recycling to production of high-valued biomaterials used by the green energy industries, in pharmaceutical products or as food supplements. In this experimental study, the temperature optimum for biomass production was tested for two species of benthic diatoms, Diatoma sp. READ MORE
