  2. 1. Issues in Urban Travel Demand Modelling : ICT Implications and Trip timing choice

    Author : Maria Börjesson; Staffan Algers; Kay Axhausen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Journey; Mathematical model; Origin traffic ; Time; Telecommuting; Journey time; Variability; Stated preference; Delay; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; 11 Road: Personal transport; 11 Road: Personal transport;

    Abstract : Travel demand forecasting is essential for many decisions, such as infrastructure investments and policy measures. Traditionally travel demand modelling has considered trip frequency, mode, destination and route choice. This thesis considers two other choice dimensions, hypothesised to have implications for travel demand forecasting. READ MORE

  4. 2. Preemption-Delay Aware Schedulability Analysis of Real-Time Systems

    Author : Filip Marković; Jan Carlson; Radu Dobrin; Björn Lisper; Enrico Bini; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-time systems; Scheduling; Schedulability analysis; Preemptions; Preemption delays; Embedded Systems; Preemptive scheduling; Response-time analysis; Cache-related preemption delay; Timing analysis; Worst-case execution time analysis; Limited-preemptive scheduling; Fixed preemption points; Computer Science; datavetenskap;

    Abstract : Schedulability analysis of real-time systems under preemptive scheduling may often lead to false-negative results, deeming a schedulable taskset being unschedulable. This is the case due to the inherent over-approximation of many time-related parameters such as task execution time, system delays, etc. READ MORE

  5. 3. When time matters : Patients’ and spouses’ experiences of suspected acute myocardial infarction in the pre-hospital phase

    Author : Ingela Johansson; Eva Swahn; Johan Herlitz; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute coronary syndrome; acute myocardial infarction; pre-hospital phase; symptom interpretation; decision-making; spouses; patient delay; ambulance utalisation; Cardiology; Kardiologi;

    Abstract : The overall aim of this thesis was to describe patients’ and spouses’ experiences of suspected acute myocardial infarction in the pre-hospital phase. A descriptive survey study was conducted to identify various factors influencing patient delay in 381 patients with suspected myocardial infarction hospitalised at a Coronary Care Unit (I) and ambulance utilisation among 110 myocardial infarction patients (II).

  6. 4. Contributions to Frequency Offset and Time Delay Estimation

    Author : Mattias Olsson; Håkan Johansson; Jonny Holmberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time delay estimation; OFDM; carrier frequency offset; Signal processing; Signalbehandling;

    Abstract : The demand for reliable high rate and efficient communication is ever increasing. In this thesis we look at two different problems in such systems, and their possible solutions. READ MORE

  7. 5. Dynamic Programming and Time-Varying Delay Systems

    Author : Bo Lincoln; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; Automatiska system; robotteknik; reglerteknik; robotics; Automation; Stability analysis; Time-varying delays; Dynamic programming; Switched linear systems;

    Abstract : This thesis is divided into two separate parts. The first part is about Dynamic Programming for non-trivial optimal control problems. The second part introduces some useful tools for analysis of stability and performance of systems with time-varying delays. READ MORE
