  1. 1. Electrically Assisted Turbocharger: Modelling And Control Strategy

    University essay from Linköpings universitet/Fordonssystem

    Author : Erik Vandor; Gabriel Ehlin; [2022]
    Keywords : EAT; VGT; VNT; Hybrid powertrain; electric turbocharger;

    Abstract : A major cause of CO2 emissions today is fossil fuel vehicles, and lowering these emissions is of key importance, resulting in increasing electrification and hybridisation nowadays. Turbochargers have been used for a long time to recycle exhaust gas heat losses to improve engine performance by compressing the intake air. READ MORE

  3. 2. Development and Analysis of a Gaseous Hydrogen-Oxygen Rotating Detonation Combustor

    University essay from KTH/Kraft- och värmeteknologi

    Author : Birgir Steinn Hermannsson; [2022]
    Keywords : ;

    Abstract : Theory suggests that more efficient rocket propulsion can possibly be achievedby utilizing a pressure-gain detonative combustion process instead of conventional deflagration combustion. To demonstrate this, rotating detonation engines that sustain one or several detonation waves in an annular enclosure havebeen a subject of research for decades. READ MORE

  4. 3. A Real- time Log Correlation System for Security Information and Event Management

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

    Author : Clémence Dubuc; [2021]
    Keywords : Correlation; SIEM; Security Logs; Apache Spark; Elastic Search; Korrelation; SIEM; Säkerhetsloggar; Apache Spark; Elastic Search;

    Abstract : The correlation of several events in a period of time is a necessity for a threat detection platform. In the case of multistep attacks (attacks characterized by a sequence of executed commands), it allows detecting the different steps one by one and correlating them to raise an alert. READ MORE

  5. 4. Implementation of a Model Predictive Controller in a Spark-Ignition Engine

    University essay from Linköpings universitet/Fordonssystem

    Author : Gustav Mann; Jakob Luedtke; [2021]
    Keywords : Model Predictive Control; SI engine; Variable Valve Timing; Throttle;

    Abstract : The propulsion of the spark-ignition engine has been investigated and developed during the past century to improve driveability, minimize fuel consumption and emissions, resulting in highly engineered and computerized powertrains. Well balanced engine maps containing coordinated set-points and model-based information sharing have solved the cross-coupling between different control loops. READ MORE

  6. 5. Assessment of the circadian stimulus potential of an integrative lighting system in an office area

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Elif Ceren Yilmaz; Rawan Abdulhaq; [2020]
