1. 1. Mapping Concurrent Applications to Multiprocessor Systems with Multithreaded Processors and Network on Chip-Based Interconnections

   Författare :Ruxandra Pop; Petru Eles; Shashi Kumar; Linköpings universitet; []
   Nyckelord :Network on Chip; Multiprocessor Embedded Systems; Task Mapping; Task Scheduling; Multithreading; Simultaneous Multithreading; Response Time Estimation; Genetic Algorithms; List Scheduling; Soft Deadline; Task Graphs; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Network on Chip (NoC) architectures provide scalable platforms for designing Systems on Chip (SoC) with large number of cores. Developing products and applications using an NoC architecture offers many challenges and opportunities. A tool which can map an application or a set of applications to a given NoC architecture will be essential. LÄS MER

3. 2. Effective cooperative scheduling of task-parallel applications on multiprogrammed parallel architectures

   Författare :Georgios Varisteas; Mats Brorsson; Avi Mendelson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multicore; parallel; scheduler; workload; runtime; task; adaptive; resource management; load balancing; work-stealing; Computer Science; Datalogi;

   Sammanfattning : Emerging architecture designs include tens of processing cores on a single chip die; it is believed that the number of cores will reach the hundreds in not so many years from now. However, most common parallel workloads cannot fully utilize such systems. LÄS MER

4. 3. Striking a balance : Managing collaborative multitasking in computer-supported cooperation

   Författare :Rikard Harr; Victor Kaptelinin; Mikael Wiberg; Oskar Juhlin; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer-supported Cooperative Work; articulation work; individual task execution; balance; interruptions; availability; awareness; interaction; information technology; multitasking; task switching; Informatics; computer and systems science; Informatik; data- och systemvetenskap;

   Sammanfattning : This thesis is a collection of six papers and a cover paper reporting an exploration of how to strike a balance between individual task execution and work articulation in Computer-supported Cooperative Work (CSCW). The interest in this theme is motivated by an increased reliance of IT-supported cooperative work arrangements in modern organizations, the fragmented layout of work for multitasking individuals and reports on various forms of overload, increased level of stress and anxiety experienced by workers active in these organizations.

5. 4. Markov Regime Switching in Economic Time Series

   Författare :Ulf Erlandsson; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik; forecasting; Markov switching; exchange rates; interest rates; business cycle; economic policy; economic systems; economic theory; econometrics; Economics; currency crisis;

   Sammanfattning : This dissertation studies statistical properties and applications of the Markov switching models for economic time series in five separate papers. The two main statistical themes are (i) the task of choosing the number of states to use in the model, and (ii) inference on time-varying transition probabilities. LÄS MER

7. 5. PROTEIN FOLD SWITCHING IN COARSE-GRAINED MODELS

   Författare :Christian Holzgräfe; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Holzgräfe; coarse-grained model; protein folding; evolution; fold switching;

   Sammanfattning : Proteins carry out the instructions encoded in genes and are crucial for many important tasks in the living organism. Often the specific three dimensional structure, or fold, of a protein enables it to carry out a given task. LÄS MER
