1. 1. Optical Communication using Nanowires and Molecular Memory Systems

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

   Författare :Thomas Kjellberg Jensen; [2024]
   Nyckelord :neuromorphic computing; nanowire; molecular dye; DASA photoswitch; OBIC; Physics and Astronomy;

   Sammanfattning : Neuromorphic computational networks, inspired by biological neural networks, provide a possible way of lowering computational energy cost, while at the same time allowing for much more sophisticated devices capable of real-time inferences and learning. Since simulating artificial neural networks on conventional computers is particularly inefficient, the development of neuromorphic devices is strongly motivated as the reliance on AI-models increases.

3. 2. Exploring potential E-fuel production pathways for maritime and aviation sectors in France : a techno-economic and environmental assessment

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Mathieu Minaud; [2024]
   Nyckelord :;

   Sammanfattning : The aviation and maritime industries pose significant challenges for decarbonization, having increased activity in the past decade. One promising solution to limit emissions in these sectors is Electrofuels (E-fuel), derived from water electrolysis hydrogen and captured CO2 or nitrogen. LÄS MER

4. 3. Heritability of methane emission in Swedish Red cattle in northern Sweden

   Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

   Författare :Lucy Chipondoro; [2024]
   Nyckelord :methane emission; heritability; swedish Red cattle; dairy cow;

   Sammanfattning : Dairy cattle contribute a significant proportion of greenhouse gases (GHG), mainly methane (CH4), among other livestock species. Methane has a negative impact on climate; therefore, its reduction is a top priority for a sustainable dairy production system. LÄS MER

5. 4. Prospects for a Free Electron Laser at the FemtoMAX Beamline

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

   Författare :Johan Holmberg; [2024]
   Nyckelord :Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

   Sammanfattning : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

7. 5. Temporary Halting of Wind Turbine Rotors toMitigate Effects on Birds

   Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Ola Hedberg; [2024]
   Nyckelord :Bird; mitigation; effect; wind farm; turbine; wind power; halting; collision; risk; birds; power; generation;

   Sammanfattning : This study assesses the viability of temporarily halting wind turbine operations as amitigation measure to protect bird populations during migration periods. Conducted in thenorthern Baltic, it examines the migration patterns, timings, and altitudes of various birdspecies, aiming to identify the most critical times for implementing turbine stoppages.
