   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Isac Lorentz; [2023]
   Keywords : Statistical analysis; regression analysis; recommender systems; ensemble learning; electronic commerce; LightGBM; learning to rank; feature selection; weather-based features; fashion; Statistisk analys; regressionsanalys; rekommendationssystem; ensemble-inlärning; näthandel; LightGBM; learning to rank; variabelselektion; väderbaserade variabler; mode;

   Abstract : Online shopping offers numerous benefits, but large product catalogs make it difficult for shoppers to understand the existence and characteristics of every item for sale. To simplify the decision-making process, online retailers use ranking models to recommend products relevant to each individual user. READ MORE

3. 7. Potential of tall oil pitch as phase change material in lignin-shelled hybrid nanocapsules for thermal energy storage.

   University essay from Mittuniversitetet/Institutionen för kemiteknik

   Author : Helena Viberg Nissilä; [2022]
   Keywords : phase change materials PCM ; tall oil pitch TOP ; lignin; nanocapsules; hybrid material; thermal storage;

   Abstract : A prospect in utilizing thermal energy in development of energy systems is by the useof phase change materials (PCMs). PCMs are materials that can store and releaseenergy during phase changes, e.g. from solid to liquid. READ MORE

4. 8. Development of CFD method to model thermal properties of laminates in a truck cab : Modeling solids and HVAC performance

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Aniruddh Mohan; [2022]
   Keywords : CFD; Conjugate heat transfer; HVAC; Shell modeling;

   Abstract : The study of Heating, Ventilation and Air Conditioning (HVAC) system performance is important to understand its energy consumption, especially for electric vehicles. The purpose of this thesis is to develop a methodology to simulate the flow within the Scania S20H cab while also capturing the thermal properties of the fluid and solids within the cab. READ MORE

5. 9. Nuclear Structure near the Proton Drip-line: A Search for Excited States in 62Ge

   University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Dalia Farghaly; [2022]
   Keywords : nuclear physics; nuclear structure; proton drip-line; excited states; germanium; fusion-evaporation reaction; experimental nuclear physics; gamma sphere; gamma spectroscopy; HPGe detectors; data analysis; Physics and Astronomy;

   Abstract : An experiment to study mirror symmetry in the mass A = 60 region was performed at the Argonne National Laboratory (ANL) in 2020. The fusion-evaporation reaction 40Ca + 24Mg → 64Ge* at a beam energy of 106 MeV was used to populate excited states in 62Ge. READ MORE

6. 10. Quantum chemical studies of the reactivity of gold nanoparticles towards molecular radicals

   University essay from KTH/Kemi

   Author : Sofia Larsson; [2022]
   Keywords : gold nanoparticles; surface electrostatic potential; average local ionization energy; electron attachment energy; free molecular radicals; guldnanopartiklar; elektrostatisk ytpotential; genomsnittlig lokal joniseringsenergi; fria molekylära radikaler;

   Abstract : Kvantkemiska studier av reaktiviteten hos guldnanopartiklar Au3-Au11 och Au13 mot O- centrerade molekylradikaler OH , OOH , OCH3   och H2O undersöks. Olika molekylära ytegenskaper tas med i beräkningen, elektrostatiska ytpotentialen, den genomsnittliga lokala joniseringsenergin, electron attachment energy och spinndensiteten (VS(r), IS(r), TS(r), ES(r) och S(r)).
