2. 1. 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

4. 2. Low-delay sensing and transmission in wireless sensor networks

   Author : Johannes Karlsson; Mikael Skoglund; Markus Flierl; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative communication; wireless sensor networks; low-delay transmission; joint source-channel coding; estimation; quantization; Telecommunication; Telekommunikation;

   Abstract : With the increasing popularity and relevance of ad-hoc wireless sensor networks, cooperative transmission is more relevant than ever. In this thesis, we consider methods for optimization of cooperative transmission schemes in wireless sensor networks. READ MORE

5. 3. 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

6. 4. 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

7. 5. Low Power Wireless Technologies for IIoT : Analysis and enhancement of communication delay, reliability and scalability

   Author : Raúl Rondón; Mikael Gidlund; Fortunato Santucci; Mittuniversitetet; []
   Keywords : ;

   Abstract : In recent years, the implementation of wireless communication systems in industrial environments has significantly increased. As a result, new applications such as Industrial Internet-of-Things (IIoT) have arisen, reshaping the future of industrial automation. READ MORE
