1. 1. Performance problem diagnosis in cloud infrastructures

   Författare :Olumuyiwa Ibidunmoye; Erik Elmroth; Guilliano Casale; Viktoria Fodor; Henrik Björklund; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems Performance; Performance anomalies; Performance bottlenecks; Cloud infrastructures; Cloud Computing; Cloud Services; Cloud Computing Performance; Performance problems; Performance anomaly detection; Performance bottleneck identification; Performance Root-cause Analysis; Computer Systems; datorteknik; Computer Science; datalogi;

   Sammanfattning : Cloud datacenters comprise hundreds or thousands of disparate application services, each having stringent performance and availability requirements, sharing a finite set of heterogeneous hardware and software resources. The implication of such complex environment is that the occurrence of performance problems, such as slow application response and unplanned downtimes, has become a norm rather than exception resulting in decreased revenue, damaged reputation, and huge human-effort in diagnosis.

3. 2. Wicked Problems in Engineering Education : Preparing Future Engineers to Work for Sustainability

   Författare :Johanna Lönngren; Magdalena Svanström; Åke Ingerman; Tom Adawi; John Holmberg; Marie Paretti; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; wicked problem; engineering education; sustainability; phenomenography; assessment; rubric; design-based research; action research; perspective shift; ill-structured problems; problem-solving; didactics of natural science; naturvetenskapens didaktik;

   Sammanfattning : Most engineering education today does not adequately prepare students to contribute to sustainability. For example, engineering students often do not learn how to address complex and ill-structured sustainability problems that involve different stakeholders, value conflicts,and uncertainty; such problems are also called wicked problems.

4. 3. Enhancing Container Terminal Performance : A Multi Agent Systems Approach

   Författare :Lawrence Henesey; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Container terminals; performance; Multi agents; Agent based technologies;

   Sammanfattning : This thesis seeks to understand and attempt to solve some of the problems that are facing many decision makers at container terminals. The growth of containerization, transporting goods in a container, has created many problems for ports, i.e. higher requirements on terminals and infrastructure. LÄS MER

5. 4. Towards Scalable Performance Analysis of MPI Parallel Applications

   Författare :Xavier Aguilar; Erwin Laure; David Black-Schaffer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel computing; performance monitoring; performance tools; event flow graphs; Computer Science; Datalogi;

   Sammanfattning :   A considerably fraction of science discovery is nowadays relying on computer simulations. High Performance Computing  (HPC) provides scientists with the means to simulate processes ranging from climate modeling to protein folding. LÄS MER

7. 5. ADHD Symptoms : Objective Performance and Subject Perspective

   Författare :Sara Scholtens; Karin Brocki; Ann-Margret Rydell; Gunilla Bohlin; Claire Hughes; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ADHD; developmental psychology; academic performance; future orientation; cognitive performance; positive illusory bias; attachment representations; Psychology; Psykologi;

   Sammanfattning : ADHD research has mainly focused on objective performance measures. Performance, however, is only one aspect of functioning. Other aspects of how individuals function are their personal experiences and their evaluations of those experiences. LÄS MER
