1. Decay Chains of Fast Alpha Emitters in the Actinide Region
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikAbstract : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. READ MORE

2. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

3. Development of a Novel Method for Automotive On-board Transmitter EMC Immunity Testing
University essay from Uppsala universitet/ElektricitetsläraAbstract : As the automotive industry advances through technology integration, components are designed to operate at increasingly higher frequencies. Consequently, there will be an increasing demand for automotive electromagnetic compatibility (EMC) testing. READ MORE

4. Phase Unwrapping MRI Flow Measurements
University essay from Uppsala universitet/Avdelningen Vi3Abstract : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. READ MORE

5. Using forest reflectance modelling to estimate albedo for narrow-view satellites
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionenAbstract : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. READ MORE
