  1. 11. Sounding Rocket ExperimentElectronics – RTL Design and Validation

    Master-uppsats, KTH/Rymd- och plasmafysik

    Författare :Ruslan Kevorkov; [2014]
    Nyckelord :;

    Sammanfattning : The Infrared Spectroscopy to Analyse the middle AtmosphereComposition (ISAAC) is an experimental module designed by KTHstudents. It consists of a Rocket Mounted Unit (RMU) and twoFree-Falling Units (FFU) carried inside. LÄS MER

  2. 12. Investigation of the behaviour of return collectors on Paris’ subway MP05 (Line 1)

    Master-uppsats, KTH/Järnvägsteknik

    Författare :Theo Le Bars; [2014]
    Nyckelord :Rubber-tyred subways; return collector; rigid solid mechanics; contact.;

    Sammanfattning : Return collectors are predominant organs for rubber-tyred subways to operatesince they ensure both the track circuit shunt and the traction current return. Po- sitioned at the interface between the track and the rolling stock, they are subjected to the disruptions linked to the train movement and the track irregularities. LÄS MER

  3. 13. System Design of Automated Test Equipment for Electrical Control Units in Trucks

    Master-uppsats, KTH/Mikro- och nanosystemteknik

    Författare :Anna Bladh; [2014]
    Nyckelord :test equpment control trucks;

    Sammanfattning : The high level of complexity in today’s electronic systems increases the demands on an advanced validation and verification process. Automated testing facilitates and improves regression testing (rerun of previously executed test cases to uncover and track new bugs) with increased coverage and reduced costs as a result. LÄS MER

  4. 14. Design and implementation of a servo system by Sensor Field Oriented Control of a BLDC motor

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Per Eriksson; [2014]
    Nyckelord :Field oriented control; Vector Control; BLDC; Servo system; Regulator; Synchronous motor; PWM; SVPWM;

    Sammanfattning : A servo system intended to steer antennas on board ships is designed, built and tested. It uses a Brushless Direct Current (BLDC) motor with an encoder to keep track of its position, and Field Oriented Control (FOC) implemented on Toshibas microprocessor TMPM373 in order to control the current flowing to the motor.

  5. 15. Home Location Register (HLR) dedicated for Short Message Service (SMS)

    Magister-uppsats, Uppsala universitet/Institutionen för informationsteknologi; Uppsala universitet/Institutionen för informationsteknologi

    Författare :Niklas Rönnblom; Johan Vikman; [2013]
    Nyckelord :;

    Sammanfattning : In telecommunication a Home Location Register (HLR) is used for keeping track of subscriber data for a multitude of services, including Circuit Switched (CS) calls, Short Message Service (SMS), and more. To support all functions, about 50 different complicated operations must be supported. LÄS MER
