  1. 1. Simulation of IB-LOCA in TRACE : A semi-blind study of numerical simulations compared to the PKL test facility

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

    Författare :Matilda Tiberg; [2022]
    Nyckelord :Pressurized Water Reactor; Safetey analysis; LOCA; Intermediate Break; PKL; TRACE; transient; thermal hydraulics;

    Sammanfattning : This thesis studied the performance of the thermal hydraulic software TRACE applied on an intermediate sized break (IB) happening on the cold leg in a pressurized water reactor (PWR), causing a loss-of-coolant accident (LOCA). The same accident has previously been simulated in the PKL Test Facility, which is a scaled version of a PWR and is used to simulate transients stemming from different accidents. LÄS MER

  3. 2. Colliding Galaxies in a (Nut)Shell

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Författare :Jonathan Petersson; [2022]
    Nyckelord :shell galaxies; simulations; starbursts; quenching; mergers; Physics and Astronomy;

    Sammanfattning : Galaxy interactions and mergers are natural recurring events in the current cosmological paradigm, events that often coincide with starbursts and enhanced star formation activity. To understand why that is, one can use idealised (non-cosmological) merger simulations, which provide freedom to recreate specific tidally distorted galaxies, and analysis of the time evolution and underlying physics of the star formation activity at a high spatial resolution.

  4. 3. En jämförande studie mellan diesel- och eldrivna tunneldrivningsmaskiner för masshantering i tunnel

    M1-uppsats, KTH/Byggteknik och design

    Författare :Chanel Semakala; Emre Cömert; [2019]
    Nyckelord :Tunnel construction; Shot rock; Electrically powered; Carbon dioxide emissions; Energy consumption; Costs Truck; Wheel loader; Tunnelbyggnation; Bergmassor; Eldrivet; Koldioxidutsläpp; Energiförbrukning; Kostnader; Lastbil; Hjullastare;

    Sammanfattning : The construction industry is facing a reality where the dependency on fossil fuels needs to cease and be replaced by options that are more climate friendly. One such option is the electrification that has not made a breakthrough in the construction industry yet and therefore needs to be examined. LÄS MER

  5. 4. Power Analysis of the Advanced Encryption Standard : Attacks and Countermeasures for 8-bit Microcontrollers

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Mattias Fransson; [2015]
    Nyckelord :power analysis; template attacks; countermeasures; microcontroller; AES;

    Sammanfattning : The Advanced Encryption Standard is one of the most common encryption algorithms. It is highly resistant to mathematical and statistical attacks, however, this security is based on the assumption that an adversary cannot access the algorithm’s internal state during encryption or decryption.

  7. 5. Implementation and Analysis of Platoon Catch-Up Scenarios for Heavy Duty Vehicles

    Master-uppsats, KTH/Reglerteknik

    Författare :Pedro F. Lima; [2013]
    Nyckelord :Heavy duty vehicle; platooning; fuel consumption; air drag reduction.;

    Sammanfattning : Heavy duty vehicle (HDV) platooning is currently a big topic both in the academic world and in industry. Platooning is a smart way to solve problems such as safety, traffic congestion, fuel consumption and hazardous exhaust emissions since its concept enables several vehicles to drive close to each other while maintaining all the security requisites.
