2. 1. 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. 2. 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

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

   Author : Olov Lindfeldt; Bo-Lennart Nelldal; Lars-Göran Mattsson; Ingo Hansen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

   Abstract : 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. READ MORE

6. 4. Low-delay sensing and transmission

   Author : Johannes Kron; Mikael Skoglund; Tor Ramstad; KTH; []
   Keywords : 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;

   Abstract : 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. READ MORE

7. 5. Applying Data Analytics to Freight Train Delays in Shunting Yards

   Author : Niloofar Minbashi; Markus Bohlin; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shunting yards; delay prediction; congestion; delay probability distributions; temporal delay distributions; Rangergodsbangårdarna; förseningsprediktion; trängsel; fördröjning av sannolikhetsdistributioner; tidsfördröjningsdistributioner; Transportsystem; Transport Systems;

   Abstract : The European Commission has foreseen a modal share of 30% by 2030 for rail freight transport. To achieve this increase in the modal share, enhanced reliability of rail freight services is required. Optimal functioning of shunting yards is one of the areas that can improve this reliability.
