1. 1. Live long and prosper : Health-promoting conditions at work

   Författare :Anna-Carin Fagerlind Ståhl; Kerstin Ekberg; Maria Gustavsson; Gun Johansson; Lotta Dellve; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : The aim of this thesis is to contribute with knowledge concerning health-promoting conditions at work, and to investigate how individual, workplace and organisational conditions are interrelated. In the thesis, work-related flow, i.e. an experience of motivation, absorption and work enjoyment, is used as a holistic notion of occupational health. LÄS MER

3. 2. Explainable and Resource-Efficient Stream Processing Through Provenance and Scheduling

   Författare :Dimitrios Palyvos-Giannas; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data Streaming; Scheduling; Provenance; Stream Processing;

   Sammanfattning : In our era of big data, information is captured at unprecedented volumes and velocities, with technologies such as Cyber-Physical Systems making quick decisions based on the processing of streaming, unbounded datasets. In such scenarios, it can be beneficial to process the data in an online manner, using the stream processing paradigm implemented by Stream Processing Engines (SPEs). LÄS MER

4. 3. A System, Tools and Algorithms for Adaptive HTTP-live Streaming on Peer-to-peer Overlays

   Författare :Roberto Roverso; Seif Haridi; Jim Dowling; Alberto Montresor; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peer-to-peer; distributed caching; nat traversal; congestion control; adaptive HTTP streaming; live streaming; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : In recent years, adaptive HTTP streaming protocols have become the de facto standard in the industry for the distribution of live and video-on-demand content over the Internet. In this thesis, we solve the problem of distributing adaptive HTTP live video streams to a large number of viewers using peer-to-peer (P2P) overlays. LÄS MER

5. 4. Resource, Data and Application Management for Cloud Federations and Multi-Clouds

   Författare :Vamis Xhagjika; Leandro Navarro Moldes; Vladimir Vlassov; Gregory Chockler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-Cloud; Geo-Distribution; Live Streaming; Locality optimisation; Multicast; Multi-Cloud Overlay; Cloud Federation; Web Real-time Communications; WebRTC-RTCWEB; Media Quality; Computer Science; Datalogi;

   Sammanfattning : Distributed Real-Time Media Processing refers to classes of highly distributed, delay no-tolerant applications that account for the majority of the data traffic generated in the world today. Real-Time audio/video conferencing and live content streaming are of particular research interests as technology forecasts predict video traffic surpassing every other type of data traffic in the world in the near future.

7. 5. Live Streaming in P2P and Hybrid P2P-Cloud Environments for the Open Internet

   Författare :Amir H. Payberah; Seif Haridi; Anwitaman Datta; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Peer-to-Peer (P2P) live media streaming is an emerging technology that reduces the barrier to stream live events over the Internet. However, providing a high quality media stream using P2P overlay networks is challenging and gives raise to a number of issues: (i) how to guarantee quality of the service (QoS) in the presence of dynamism, (ii) how to incentivize nodes to participate in media distribution, (iii) how to avoid bottlenecks in the overlay, and (iv) how to deal with nodes that reside behind Network Address Translators gateways (NATs).
