1. 1. Analysis on copper, lead and tin removal in steel scrap sorting : Technologies involved, environmental considerations and economic aspects

   University essay from KTH/Materialvetenskap

   Author : Giada Cavaliere; [2023]
   Keywords : Copper; Tin; Lead; Steel Scrap Sorting; Ballistic Separation; Dilution; Revenue Modelling; CO2 emissions Modelling; Tenn; Bly; Sortering av stålskrot; Ballistisk separation; Utspädning; lntäktsmodellering; CO2-utsläppsmodellering;

   Abstract : With the urgency of cutting down CO2 emissions to reach climate neutrality by 2050, decarbonization of the steel industry is on the European Commission's agenda. Steelmaking accounts for 10 % of anthropogenic CO2 emissions and it is one of the most challenging sectors to decarbonize. READ MORE

3. 2. Dynamic Covariance Modelling Using Generalised Wishart Processes

   University essay from Lunds universitet/Matematisk statistik

   Author : Fredrik Nilsson; [2023]
   Keywords : Covariance matrix; generalised Wishart process; Bayesian inference; Markov chain Monte Carlo; Hamiltonian Monte Carlo; Mathematics and Statistics;

   Abstract : Modern portfolio theory was pioneered by Markowitz who formulated the mean-variance problem, without which any discussion on quantitative approaches to portfolio selection would be incomplete. The framework boils down to finding the expected return $\mu$ and covariance $\Sigma$, after which the solution is proportional to $\Sigma^{-1}\mu$. READ MORE

4. 3. Hydraulic modelling at Finsjö Övre hydropower plant : Study for evaluation of a fishway's attractiveness

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Eddie Blomström; [2022]
   Keywords : fishway; flow; hydraulics; HEC-RAS;

   Abstract : In connection with the government’s approval on the proposed national plan (NAP) in 2019, it has become highly topical to find solutions problems regarding fish migration in Swedish watercourses. At Finsjö Övre hydropower plant in Emån, a new type of fishway is planned to be installed and evaluated starting at the end of 2022. READ MORE

5. 4. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors

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

   Author : Lassi Linnala; [2022]
   Keywords : femtosecond THz radiation; ultrafast x-ray diffraction; pump-probe; longitudinal optical phonons; zincblende semiconductors; anharmonic decay; density functional perturbation theory; Physics and Astronomy;

   Abstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.

6. 5. Modelling and Optimization of Simultaneous Froward- and Reverse Logistics as Capacitated Vehicle Routing Problem : An optimization simulation model problem

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

   Author : Md Kamrul Islam; [2022]
   Keywords : Optimization; Last-mile delivery; VRP; Capacitated Vehicle Routing Problem; Green Vehicle Routing Problem; CO2 emissions.;

   Abstract : Environmental issues are a vital concern in today’s world. The Swedish government and local businesses are developing a sustainable business and eco-friendly environment for city inhabitants. Last-mile pickup and delivery services are a key concern, which significantly impacts the environment and society. READ MORE
