  1. 1. Energy Harvesting for Health Monitoring Balises : Analytical study

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

    Author : Leire Carreras Orobengoa; [2021]
    Keywords : Balise; Energy harvesting; Railway signaling; Wireless communication networks;

    Abstract : Balises are transponders installed in railways. These devices are nowadays powered by means of a radiofrequency signal emitted by each running train that passes above them. It is only during this moment that the health state of the balises is checked. READ MORE

  2. 2. Simulation of air quality in underground train stations

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Benjamin Söderberg; [2020]
    Keywords : PM10; aerosols; air pollution; particulate matter; emission factors; underground train station; PM10; luftkvalité; tåg; emissionsfaktorer; underjordiska tågstationer;

    Abstract : Particulate matter (PM) is a widespread air pollutant of microscopic particles that are suspended in the atmosphere. There is high concentration of PM in underground train stations and tunnels. The concentration of particulate matter (PM10) measured in Stockholm’s metro varies significantly between day and nighttime traffic of trains. READ MORE

  3. 3. Stabilization of Constant Power Loads Using Model Predictive Control

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

    Author : Mikael Glamheden; [2020]
    Keywords : ;

    Abstract : This thesis considers stabilization of constant power loads (CPLs) fed by a dcpower source through an input filter, using model predictive control (MPC).Train propulsion systems generally utilize electrical motors whose output torqueis tightly regulated by power converters. Often, these systems behave as CPLs. READ MORE

  4. 4. Maglev deployment in winter climate

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Axel Thorstrand; [2020]
    Keywords : ;

    Abstract : As of year 2020, maglev train systems are not in service in areas with harsh winter climate. Compared to conventional railway, the technology is relatively new and untested in conditions of low temperatures, icing and snow. READ MORE

  5. 5. Passenger Influence on Dwell Time : A Case Study on the Light Rail Transit Line Tvärbanan in Stockholm

    University essay from KTH/Optimeringslära och systemteori; KTH/Optimeringslära och systemteori

    Author : Felix Mir; Fredrik Rahm; [2020]
