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

    University dissertation from Stockholm : KTH

    Author : Maria Börjesson; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur; Travel Demand; ICT; Tele-substitution; Revealed Preference; Stated Preference; Mixed Logit; Unobserved Heterogeneity; Travel Time Uncertainty; Schedule Delay; 11 Road: Personal transport; 11 Road: Personal transport; Journey; Mathematical model; Origin traffic ; Time; Telecommuting; Journey time; Variability; Stated preference; Delay;

    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

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

    University dissertation from Västerås : Mälardalen University

    Author : Filip Marković; Jan Carlson; Radu Dobrin; Björn Lisper; Enrico Bini; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

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

    University dissertation from Institutionen för medicin och vård

    Author : Ingela Johansson; Eva Swahn; Johan Herlitz; [2006]
    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; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Cardiology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin 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).

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

    University dissertation from Institutionen för systemteknik

    Author : Mattias Olsson; Håkan Johansson; Jonny Holmberg; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time delay estimation; OFDM; carrier frequency offset; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik 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

  5. 5. Enhancing the Performance of Distributed Real-time Systems

    University dissertation from Göteborg : Chalmers university of technology

    Author : Hoai Hoang; Högskolan i Halmstad.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi; Switched Ethernet; Real-Time Communication; EDF scheduling; Reducation of delay and jitter; reduction of delay; real-time communication;

    Abstract : Advanced embedded systems can consist of many sensors, actuators and processors that are deployed on one or several boards, while having a demand of interacting with each other and sharing resources. Communication between different components usually has strict timing constraints. READ MORE
