1. 11. The two-Higgs-doublet modelas an explanation for the muon (g−2) discrepancy

   Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Zenny Wettersten; [2020]
   Nyckelord :Beyond Standard Model; BSM; CP violation; Higgs Physics; two Higgs doublet model; 2hdm; Physics and Astronomy;

   Sammanfattning : The general Z2-violating two-Higgs-doublet model (2HDM) is analysed as an explanation for the discrepancy between Standard Model predictions and experimental measurements of the muon anomalous magnetic dipole moment ∆aµ, with the condition that it does not provide an electron electric dipole moment |eEDM| larger than experimental bounds. Several point studies of individual 2HDM parameter space points are made to show large-scale cancellation among Barr-Zee 2-loop contributions to |eEDM| at large Yukawa lepton sector magnitudes, as well as an approximately linear growth of total aµ contribution when those magnitudes are rescaled by a common factor, reaching the same order as ∆aµ.

3. 12. Relativistic attosecond electron pulses by laser wakefield acceleration

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

   Författare :Cornelia Gustafsson; [2020]
   Nyckelord :laser wakefield accelerator; laser wakefield acceleration; attosecond; electron pulses; Physics and Astronomy;

   Sammanfattning : The search for cheaper and more compact accelerators has led to the development of laser-driven plasma-based accelerators. In comparison to conventional particle accelerators, the plasma-based accelerator is inherently insensitive to the breakdown of the acceleration structure and therefore greater accelerating fields can be obtained.

4. 13. Evaluation of Peridynamics and Its Application in Harmonic-Structured Material Simulations

   Master-uppsats, Lunds universitet/Mekanik

   Författare :Theodor de Sousa; [2020]
   Nyckelord :peridynamics; peridigm; harmonic-structured materials; computational mechanics; fracture modelling; Technology and Engineering;

   Sammanfattning : Materials are constantly sought to be improved in different manners. Two of the most common characteristics to improve are strength, and ductility. Historically, materials are modified homogeneously to achieve improvement, while the past century has also seen composite materials becoming standard-issue within various industries. LÄS MER

5. 14. Analysis of chlorophyll synthesis mutants xantha-m and xantha-j of Hordeum vulgare L.

   Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

   Författare :Fredrik Klinghammer; [2020]
   Nyckelord :Biology and Life Sciences;

   Sammanfattning : The xantha phenotype of barley is observable as a yellow plant and caused by an inability to correctly synthesize chlorophyll. Chlorophyll is a tetrapyrrolic pigment containing magnesium, and is integral for photosynthesis in plants. LÄS MER

7. 15. Continued integration of simulated vehicle model for software verification in CANoe and Simulink

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Johan Persson; [2020]
   Nyckelord :CANoe; CAN; BorgWarner; Simulation; Vehicle Model; Test; Technology and Engineering;

   Sammanfattning : This Master’s thesis investigates if a previously integrated Simulink based vehicle model works for testing and verifying software on an ECU (electronic control unit) used to control a four-wheel drive coupling in cars. The testing is done through a specific program called CANoe that allows the tester to both develop and run test cases. LÄS MER
