  1. 11. Strategic passenger-oriented timetable design : Long-term timetable designs with minimised passenger inconvenience

    University essay from KTH/Transportplanering

    Author : Yari de Graaf; [2021]
    Keywords : ;

    Abstract : Timetable development and design is a complex process that is crucial for safe and efficient railway operations. The combination of steel wheels and steel rails makes it possible to create trains and to transport many vehicles, thus passengers and freight, at the same time, but it also results in longer braking distances.

  3. 12. Classification of Flying Qualities with Machine Learning Methods

    University essay from KTH/Flygdynamik

    Author : Ola Isaksson; [2021]
    Keywords : Flying Qualities; Machine Learning; Flight Mechanics; Flygkvaliteter; Maskininlärning; Flygmekanik;

    Abstract : The primary objective of this thesis is to evaluate the prospect of machine learning methods being used to classify flying qualities based on simulator data (with the focus being on pitch maneuvers). If critical flying qualities could be identified earlier in the verification process, they can be further invested in and focused on with less cost for design changes of the flight control system.

  4. 13. Pre-study of optical LED units for shunting signals

    University essay from KTH/Hälsoinformatik och logistik

    Author : Tobias Adolfsson; Axel Dellenby; [2021]
    Keywords : LED - Light Emitting Diode; Booster Converter; MLCC - Multi-layer capacitor; ESR - Equivalent Serie Resistance; OU - Optical Unit; Reactive compensation; LED - lysdiod; step-up omvandlare; MLCC - flerskiktskeramisk kondensator; ESR - ekvivalent serie motstånd; OU - optiskt enhet; reaktiv kompensering;

    Abstract : Alstom wanted to investigate the possibility of adapting its light emitting diode (LED) technology for shunting signals in train traffic. The LED technology uses 50V, but Alstom wants to adapt it for 12V. The LED technology is energy efficient but needs to be adapted for existing signal interlocking by drawing a higher current.

  5. 14. Federated Emotion Recognition with Physiological Signals- GSR

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Tara Hassani; [2021]
    Keywords : Emotion Recognition; Physiological Signals; GSR; Privacy; Machine Learning; Federated Learning.;

    Abstract : Background: Human-computer interaction (HCI) is one of the daily triggering emotional events in today’s world and researchers in this area have been exploring different techniques to enhance emotional ability in computers. Due to privacy concerns and the laboratory's limited capability for gathering data from a large number of users, common machine learning techniques that are extensively used in emotion recognition tasks lack adequate data collection.

  6. 15. Automation of Pulse Repetition Interval Modulation Classification

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

    Author : Karolina Barrios; [2021]
    Keywords : ;

    Abstract : Radar systems are essential in the field of electronic warfare and radar signals are used for estimating speed, location and direction of an object. A radar system sends out small transmissions called pulses. The interval between the start of one pulse to the start of the next pulse is called pulse repetition interval (PRI). READ MORE
