  2. 6. Contributions to Delay, Gain, and Offset Estimation

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

    Abstract : 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. READ MORE

  4. 7. Quality of control and real-time scheduling : allowing for time-variations in computer control systems

    Author : Martin Sanfridson; KTH; []
    Keywords : real-time scheduling; sampled-data control. Performance measure; quality of control;

    Abstract : The majority of computers around us are embedded in productsand dedicated to perform certain tasks. A specific task is thecontrol of a dynamic system. The computers are ofteninterconnected by communication networks forming a distributedsystem. READ MORE

  5. 8. LQG-Based Real-Time Scheduling and Control Codesign

    Author : Yang Xu; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LQG control; Real-time system; Scheduling; Time-delay system;

    Abstract : Having multiple control tasks concurrently running on a single computing platform increases the processor utilization but degrades the control performance due to delay and jitter. In scheduling and control codesign, the objective is to optimize the combined performance of all the controllers, subject to a schedulability constraint. READ MORE

  6. 9. Continuous-Time Delta-Sigma Modulators for Wireless Communication

    Author : Mattias Andersson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; return-to-zero; A D converter; loop delay; delta-sigma; ADC; CMOS; STF; continuous-time; sigma; delta; filtering; CT; RZ;

    Abstract : The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. READ MORE

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

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

    Abstract : 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. READ MORE
