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

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

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

   Sammanfattning : 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. LÄS MER

3. 2. Investigating the use of Semiconductor Nanowires for Neural Networks

   Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Alfredo Serafini; [2022]
   Nyckelord :FDTD method and simulation; optical broadcasting neural network; optical communication of nanowires; sub-wavelength absorption.; Physics and Astronomy;

   Sammanfattning : In this work, we intend to employ nanowires for the realisation of an artificial neuron which can be used to design a neural network that will guide the new generation of non-von Neumann architectures such as Neuromorphic Computing. Possible applications are strongly related to Neuromorphic architectures and artificial intelligence, such as high-performance computers, robotics hardware and autonomous drones. LÄS MER

4. 3. Inverse source modeling of roll induced magnetic signature

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

   Författare :Erik Thermaenius; [2022]
   Nyckelord :inverse modeling; inverse; modeling; magnetic; signature; source modeling; tikhonov; roll; magnetic silencing; regularization; regularisation; induction; dipole; dipoles; Helmholtz; inversmodellering; magnetisk; signatur; källmodellering; rullning; rullningsinducerad; regularisering; dipol; dipoler;

   Sammanfattning : Vessels constructed in electrically conductive materials give rise to frequency-dependent, induced magnetic fields when waves of water cause them to roll in the Earth's magnetic field. These fields, typically referred to as roll-induced magnetic vortex fields, are a component of the ship's overall signature, where signature refers to measurable quantities which can reveal or identify objects.

5. 4. Sustaining Orientation of Ubiquitin for Single Particle Imaging Using Electric Fields

   Kandidat-uppsats, Uppsala universitet/Kemisk och biomolekylär fysik; Uppsala universitet/Energimaterialens fysik

   Författare :Adi Bijedic; [2021]
   Nyckelord :;

   Sammanfattning : Single-particle imaging, or SPI, is a method used to obtain the three-dimensional structure of particles. Repeatedly aiming X-rays at samples of a particle produces diffraction patterns, which are combined to a best-fit three-dimensional model of the particle. SPI of proteins can be improved by orienting the protein before imaging. LÄS MER

7. 5. Processing of Noisy Controlled Source Audio Magnetotelluric (CSAMT) Data

   Master-uppsats, Uppsala universitet/Geofysik

   Författare :Julia Fridlund; [2019]
   Nyckelord :CSAMT; noise; magnetotelluric transfer functions; robust processing; transients; bias; CSAMT; brus; magnetotelluriska överföringsfunktioner; robust processering; transienter; bias;

   Sammanfattning : Controlled Source Audio Magnetotellurics (CSAMT) is a geophysical method for characterizing the resistivity of the subsurface with the help of electromagnetic waves. The method is used for various purposes, such as geothermal- and hydrocarbon exploration, mineral prospecting and for investigation of groundwater resources. LÄS MER
