  1. 1. Gate driver solutions for high power density SMPS using Silicon Carbide MOSFETs

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Farhan Akram; [2021]
    Keywords : SiC MOSFETs; Gate drivers; DC-DC converter; High power and efficiency power supplies;

    Abstract : Discrete silicon carbide (SiC) power devices have unique characteristics that outpace those of silicon (Si) counterparts. The improved physical features have provided better faster switching, greater current densities, lower on-resistance, and temperature performances. READ MORE

  2. 2. Impact of different primary particles on Geant4 simulation execution time - study on protons and pions

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

    Author : Rebecca Jigström Madeira; [2021]
    Keywords : Geant4; Monte Carlo method; Large Hadron Collider; simulation time; collider experiment; Physics and Astronomy;

    Abstract : The High Luminosity Large Hadron Collider (HL-LHC) at CERN, an improvement to the LHC, scheduled to be operating in 2027, will further the potential for scientific breakthroughs in High Energy Physics. The project’s demand in computational resources, however, is predicted to exceed what will be available then. READ MORE

  3. 3. Emission reduction in waste incineration : A comparison of three applicable measures

    University essay from Uppsala universitet/Byggteknik och byggd miljö

    Author : Adam Linde; [2021]
    Keywords : Waste; Carbon dioxide; Sorting; Requirement Specification; CCS; BECCS;

    Abstract : Utilization of waste as fuel for heat and power production is commonplace in Sweden, and the fossil emissions from the incineration of waste is primarily derived from the share of plastics in the fuel. Reducing the share of fossil material in the fuel should therefore lead to diminished local emissions. READ MORE

  4. 4. Horses vs. Machines: A Comparative Energy Analysis between Eighteenth Century- and Modern Copper Mining

    University essay from Lunds universitet/Humanekologi

    Author : Amos Strömberg; [2021]
    Keywords : Copper mining; embodied energy; small-scale mining; degrowth; copper ore grade; Podolinsky’s principle; large-scale mining; 18th century mining; mining; Social Sciences;

    Abstract : This study shows the positive benefits of early 18th century copper mining in terms of energy efficiency due to the utilization of animate power, pre-industrial machinery, biofuels and a small-scale of organization. Based on the concept of embodied energy, this study calculates the inputs in early 18th century Falun Coppermine in Sweden and compares it with present-day Chibuluma Coppermine in Zambia. READ MORE

  5. 5. Deep Reinforcement Learning for Autonomous Highway Driving Scenario

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

    Author : Neil Pradhan; [2021]
    Keywords : Deep reinforcement learning; Highway driving scenario; Tactical decision making; fuel reduction; high-level decision making; autonomous driving; Partially Observable Markov Decision Process POMDP .; Lärande om djupförstärkning; motorvägsscenario; taktiskt beslutsfattande; bränslereduktion; beslut på hög nivå; autonom körning; Partially Observable Markov Decision Process POMDP ;

    Abstract : We present an autonomous driving agent on a simulated highway driving scenario with vehicles such as cars and trucks moving with stochastically variable velocity profiles. The focus of the simulated environment is to test tactical decision making in highway driving scenarios. READ MORE
