1. 36. On Deep Machine Learning Based Techniques for Electric Power Systems

   Författare :Ebrahim Balouji; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deep Learning; Cable faults; phase locked loop; Flicker; Harmonics and Interharmonics; Reinforcement learning; Voltage Dip; Active Power filter; Machine Learning; Voltage fluctuation; Partial Discharges;

   Sammanfattning : This thesis provides deep machine learning-based solutions to real-time mitigation of power quality disturbances such as flicker, voltage dips, frequency deviations, harmonics, and interharmonics using active power filters (APF). In an APF the processing delays reduce the performance when the disturbance to be mitigated is tima varying. LÄS MER

3. 37. Belt Driven Alternator and Starter with a Series Magnetized Synchronous Machine Drive

   Författare :Tomas Bergh; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Electric Hybrid Vehicles, EHV, are under development to provide lower fuel consumption levels and minimize the environmental pollution compared to pure Internal Combustion Engine, ICE, driven vehicles. The EHV is more complex and thus carry many more extra parts than the pure ICE based vehicle. LÄS MER

4. 38. Lung-resident, M2e-specific CD4 T cells critically protect during influenza infection

   Författare :Ajibola Omokanye; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; influenza; vaccine; universal; heterosubtypic; M2e; CD4; Th17; ThCTL; tissue-resident; cytotoxic; single-cell RNA-seq;

   Sammanfattning : Memory CD4+ T cells are a critical component of the adaptive immune response to fight infection. However, current vaccines against influenza only focus on the other arm of adaptive immunity—triggering B cells to produce antibodies. LÄS MER

5. 39. Development and evaluation of a subunit DIVA vaccine against bluetongue virus serotype 8 in cattle

   Författare :Jenna Anderson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Bluetongue virus (BTV) causes the primarily vector-borne bluetongue disease of ruminants, which poses a permanent threat to Europe since new serotypes and strains are frequently introduced. Vaccination of cattle is essential to control BTV outbreaks. LÄS MER

7. 40. Anomaly and Topology : On the axial anomaly, domain wall dynamics, and local topological markers in quantum matter

   Författare :Julia D. Hannukainen; Jens H. Bardarson; Adolfo G. Grushin; Teemu Ojanen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chiral anomaly; axial anomaly; topological phases of matter; Weyl semimetals; magnetic domain walls; local topological markers;

   Sammanfattning : Chiral anomalies and topological phases of matter form the basis of the research presented in this dissertation. The chiral anomaly is considered both in the context of magnetic Weyl semimetals and in the context of non-Hermitian Dirac actions. LÄS MER
