  1. 1. Towards Active Car Body Suspension in Railway Vehicles

    Författare :Jessica Fagerlund; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupling; Model reduction; Active suspension; MIMO systems; LQ control;

    Sammanfattning : Today, most railway suspension systems are passive. The most wide-spread exception isactive car body tilt systems, which are mounted in some high-speed trains. Replacingsome of the passive suspension components with active could reduce the weight and costof the vehicle. LÄS MER

  2. 2. Mechanics and acoustics of violin bowing Freedom, constraints and control in performance

    Detta är en avhandling från Stockholm : KTH

    Författare :Erwin Schoonderwaldt; KTH.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; bow-string interaction; bowed string; violin playing; motion capture; bowing parameters; performance control; NATURAL SCIENCES Physics Other physics; NATURVETENSKAP Fysik Övrig fysik; HUMANITIES and RELIGION Aesthetic subjects Music; HUMANIORA och RELIGIONSVETENSKAP Estetiska ämnen Musikvetenskap;

    Sammanfattning : This thesis addresses sound production in bowed-string instruments from two perspectives: the physics of the bowed string, and bow control in performance. Violin performance is characterized by an intimate connection between the player and the instrument, allowing for a continuous control of the sound via the main bowing parameters (bow velocity, bow force and bow-bridge distance), but imposing constraints as well.

  4. 4. Embedded Measurement Systems

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Lars Bengtsson; Göteborgs universitet.; Gothenburg University.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microcontroller; measurement system; direct sensor-to-controller; time-to-digital converter; phase detector; lock-in amplifier;

    Sammanfattning : The subject of Embedded Measurement Systems (EMS) is the merging of embedded systems and electrical measurement systems. This indicates that EMSs are hardware-software systems dedicated to measuring one or a few physical quantities. LÄS MER

  5. 5. Active Flow Control for Aircrafts and Heavy Vehicles

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Mohammad El-Alti; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trucks; Drag reduction; Bluff-body; Large-eddy Simulation; Wake; Tilt-rotor wing; optimization; Aircrafts; Heavy vehicles; Active and Passive Flow Control; Response surface methodology; Synthetic-jet Actuator;

    Sammanfattning : Bluff-body flows are dominated by large dissipative vortex-shedding wakes with low mean pressure compared to the high pressure on their frontal area. This induced pressure difference is the major contribution to the total aerodynamic drag. LÄS MER
