2. 6. Control Strategies for Improving Cloud Service Robustness

   Author : Jonas Dürango; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis addresses challenges in increasing the robustness of cloud-deployed applications and services to unexpected events and dynamic workloads. Without precautions, hardware failures and unpredictable large traffic variations can quickly degrade the performance of an application due to mismatch between provisioned resources and capacity needs.

4. 7. The Quest for Edge Awareness, Lessons not yet learned : PhD Thesis on practical and situated usefulness of advanced technological systems among inescapable uncertainties and competing interests in a world of dynamic changes

   Author : Patrik Stensson; Anders Jansson; Pär Ågerfalk; Martin Norsell; Erik Hollnagel; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; critical realism; human factors; situation awareness; resilience engineering; human-machine interaction; automation; autonomy; situated usefulness; systems thinking; sociotechnical systems; edge awareness; Människa-dator interaktion; Human-Computer Interaction;

   Abstract : This thesis problematizes the concept of usefulness, in part by taking questions to the extreme. The starting point is the contemporary view of usefulness, a view that remains within a traditional paradigm of technical rationality in which important aspects are disregarded or not perceived because they are not part of the equation.

5. 8. Bottlenecks and blowflies : Speciation, reproduction and morphological variation in Lucilia

   Author : Ann-Britt Florin; Lisa Meffert; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Population size; speciation; Lucilia sericata; morphological variation; Lucilia illustris; bottlenecks; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Animal Ecology; zooekologi;

   Abstract : This thesis attempts to improve our understanding of the role of population size for the process of speciation. First, the effect of population size on speciation is studied using several meta-analyses of published laboratory experiments. READ MORE

6. 9. Facility layout design with simulation-based optimization : A holistic methodology including process, flow, and logistics requirements in manufacturing

   Author : Enrique Ruiz Zúñiga; Anna Syberfeldt; Matías Urenda Moris; Masood Fathi; Jesús Muñuzuri; Högskolan i Skövde; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production and Automation Engineering; Produktion och automatiseringsteknik;

   Abstract : Adaptability and flexibility are becoming key concepts in manufacturing. Today manufacturing companies often have to deal with random disruptive events, which necessitates significantly more complex manufacturing systems. READ MORE

7. 10. Runtime Management of Multiprocessor Systems for Fault Tolerance, Energy Efficiency and Load Balancing

   Author : Stavros Tzilis; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Tolerance; Algorithms; Runtime Management; Multiprocessors; Performance; Adaptive Systems; Load Balancing; Energy Efficiency;

   Abstract : Efficiency of modern multiprocessor systems is hurt by unpredictable events: aging causes permanent faults that disable components; application spawnings and terminations taking place at arbitrary times, affect energy proportionality, causing energy waste; load imbalances reduce resource utilization, penalizing performance. This thesis demonstrates how runtime management can mitigate the negative effects of unpredictable events, making decisions guided by a combination of static information known in advance and parameters that only become known at runtime.
