1. 21. Techno-economic Analysis and Market Potential Study of Solar Heat in Industrial Processes : A Fresnel Direct Steam Generation case study

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

   Författare :Guillermo de Santos López; [2021]
   Nyckelord :Solar heat in industrial processes; techno-economic analysis; market potential; direct steam generation; Fresnel technology;

   Sammanfattning : The industrial sector not only has a big contribution to global emissions but also a low share of renewable energy for heat demand. Knowing that most of the energy consumption in industry is heat and that half of it is at medium-low temperature (below 400 ºC), it is a great market for the integration of solar thermal technologies.

3. 22. Ω- Yields in pp Events at √s = 13 TeV Using the ALICE Detector

   Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Henrik Pålsson; [2021]
   Nyckelord :LHC; ALICE; strangeness enhancement; charged multiplicity; Physics and Astronomy;

   Sammanfattning : Ω- is a baryon which is rarely produced in proton collisions. The theoretical models for how these Ω- appear are yet not fully developed. Previous studies have shown that the experimental data did not agree with the models since more Ω- particles appeared in the proton collisions than expected. LÄS MER

4. 23. Gamma-ray tracking using graph neural networks

   Master-uppsats, KTH/Fysik

   Författare :Mikael Andersson; [2021]
   Nyckelord :Physics; Nuclear Physics; Detectors; Tracking; Neural Networks; GNN; Gamma-ray; Fysik; Kärnfysik; Detektorer; Tracking; Neurala Nät; GNN; Gammastrålning;

   Sammanfattning : While there are existing methods of gamma ray-track reconstruction in specialized detectors such as AGATA, including backtracking and clustering, it is naturally of interest to diversify the portfolio of available tools to provide us viable alternatives. In this study some possibilities found in the field of machine learning were investigated, more specifically within the field of graph neural networks. LÄS MER

5. 24. The myths and hazardous life of asphalt labourer : A pre-study on work environment and gender equality in the asphalt paving industry

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

   Författare :Pipar Julia Bahri; [2020]
   Nyckelord :Asphalt; road construction; male-dominated industries; safety work; gender equality; microwave heater; attractive workplace; Asfalt; vägarbete; mansdominerade industrier; säkerhetsarbete; jämställdhet; mikrovågsvärmare; attraktiva arbetsplatser;

   Sammanfattning : Road construction work is often regarded to be a dirty and strenuous job. The asphalt paving industry is male-dominated with a low percentage of women. This master thesis is part of Human Work Sciences at Luleå University of Technology's participation in the SMMART (Swedish Magnetite Microwave Asphalt Road Technology) project. LÄS MER

7. 25. Neutrino oscillations at very high energy/matter density

   Master-uppsats, KTH/Fysik

   Författare :Mathilde Guillaud; [2020]
   Nyckelord :Theoretical Physics; Neutrino Oscillations; Astrophysical Neutrinos; Teoretisk fysik; Neutrinooscillationer; Astrofysiska neutriner;

   Sammanfattning : Neutrino oscillations in matter can be studied in different regimes, depending on the energy of the incoming neutrinos and the matter density of the medium. In this thesis we investigate neutrino oscillations in dense matter at very high energy (TeV-PeV range), taking into account the absorption that the neutrinos may undergo in such dense media. LÄS MER
