1. Multi-Parameter Modelling of Surface Electromyography Data
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : Ytelektromyografi (sEMG) mäter skelettmuskelfunktionen genom att registrera muskelaktivitet från hudens yta. Tekniken kan användas för att diagnostisera neuromuskulära sjukdomar och som ett hjälpmedel vid rehabilitering, biomedicinsk forskning och för interaktion mellan människa och dator. READ MORE

2. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. READ MORE

5. Contribution to the Understanding of the Effects of Propagation through the Ionosphere of P-band SAR Data
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : The BIOMASS mission from the European Space Agency (ESA) is designed to measurebiomass and carbon content in Earth’s forests. To account for phase changes caused byionospheric variations, a map-drift autofocus algorithm is developed, which utilises a phasescreen of the ionosphere to eliminate phase errors in the signal.
