  2. 1. Speed Choice : The Driver, the Road and Speed Limits

    Author : Mats Haglund; Nils Petter Gregersen; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Driving behaviour; Speed choice; Risk estimates; Enforcement; Attitudes; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Speed choice is one of the more characteristic features of driver behaviour. The speed a driver chooses to travel at determines the degree of difficulty he or she operates under. Higher speeds lead to more accidents, higher accident risk and more severe consequences of an accident. READ MORE

  4. 2. Measurement systems and process orientation with focus on the order process

    Author : Anders Ljungberg; Teknisk logistik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process measurement; measurement systems; process management; measurement; Technological sciences; Teknik;

    Abstract : The inability of organisations to develop successfully and their lack of a holistic view and of relevant quantitative facts are factors that played a major role in my choice of a research area for this and my licentiate thesis (Ljungberg, 1994). These two theses together represent the work conducted for the PhD degree. READ MORE

  5. 3. Speed characteristics of urban streets based on driver behaviour studies and simulation

    Author : Karin F. M. Aronsson; Karl-Lennart Bång; Bengt Holmberg; KTH; []
    Keywords : Speed; Characteristics; Urban area; Road network; Street; Traffic; Driver; Side-friction element; Driving simulator; Simulation; Measurement; Behaviour; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The objective of the study was to gain in-depth knowledge of speed relationships for urban streets. The speed characteristics were examined using a number of methods for data collection. READ MORE

  6. 4. Embedded Measurement Systems

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

    Abstract : 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. READ MORE

  7. 5. Synchronous Reluctance Machine (SynRM) in Variable Speed Drives (VSD) Applications

    Author : Reza Rajabi Moghaddam; Chandur Sadarangani; Alfredo Vagati; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synchronous Reluctance Machine SynRM ; Torque; Torque Ripple; Design; Optimization; FEM; Control; Standard Size; Measurement; Performance Comparison; Induction Machine IM ; Interior Permanent Magnet Machine IPM ; Variable Speed Drive VSD ; General Purpose GP ; Field Oriented Control FOC ; Direct Torque Control DTC ; Heat Run; Test; Thermal; Operation Diagram; Circle Diagram; Electrical engineering; Elektroteknik;

    Abstract : This thesis is comprehensively dedicated to the theoretical and experimental reevaluation of the Synchronous Reluctance Machine (SynRM). A simple approach to derive the SynRM main characteristics and behavior is followed. An introduction to an evaluation of the different control strategies in is given. READ MORE
