  1. 1. Contributions to Delay, Gain, and Offset Estimation

    Författare :Mattias Olsson; Håkan Johansson; Per Löwenborg; Markku Renfors; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time interleaved analog to digital conversion; delay estimation; OFDM; fractional delay filters; Signal processing; Signalbehandling;

    Sammanfattning : The demand for efficient and reliable high rate communication is ever increasing. In this thesis we study different challenges in such systems, and their possible solutions. LÄS MER

  2. 2. Children's health and developmental delay : positive functioning in every-day life

    Författare :Lena Almqvist; Mats Granlund; Dale Farren; Örebro universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; health; positive functioning; participation; engagement; children; developmental delay; disabilities; Psychology; Psykologi; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Psykologi; Psychology;

    Sammanfattning : The general aim of this thesis was to gain understanding of what patterns of child and environment characteristics that promote and sustain health and positive functioning of children with and without developmental delay or disabilities. The focus was on promotion of strengths and competencies rather than on prevention of risk factors, with an emphasis on children’s functioning in every-day life. LÄS MER

  3. 3. Railway operation analysis : Evaluation of quality, infrastructure and timetable on single and double-track lines with analytical models and simulation

    Författare :Olov Lindfeldt; Bo-Lennart Nelldal; Lars-Göran Mattsson; Ingo Hansen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Railway operation; Railway capacity; Single-track; Double-track; Partial double-track; Inter-station distance; Delay; Delay propagation; Crossing; Overtaking; Timetable flexibility; Simulation; Experimental design; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : This thesis shows the advantages of simple models for analysis of railway operation. It presents two tools for infrastructure and timetable planning. It shows how the infrastructure can be analysed through fictive line designs, how the timetable can be treated as a variable and how delays can be used as performance measures. LÄS MER

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

    Författare :Maria Börjesson; Staffan Algers; Kay Axhausen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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; Travel Demand; ICT; Tele-substitution; Revealed Preference; Stated Preference; Mixed Logit; Unobserved Heterogeneity; Travel Time Uncertainty; Schedule Delay;

    Sammanfattning : 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. LÄS MER

  5. 5. Low-delay sensing and transmission

    Författare :Johannes Kron; Mikael Skoglund; Tor Ramstad; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative communication; wireless sensor networks; low-delay transmission; joint source-channel coding; distributed source coding; estimation; quantization; Telecommunication; Telekommunikation;

    Sammanfattning : This thesis studies cooperative sensing and transmission in the context ofwireless sensor networks (WSNs). We especially focus on two means of cooperative sensing and transmission, namely, distributed source coding and relaying. LÄS MER
