1. 6. Coordinated Transmission for Wireless Interference Networks

   Författare :Hamed Farhadi; Mikael Skoglund; David Gesbert; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interference; Wireless Network; MIMO; Coordinated Transmission; Resource Allocation; Interference Alignment; Scheduling; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Wireless interference networks refer to communication systems in which multiple source–destination pairs share the same transmission medium, and each source’s transmission interferes with the reception at non-intended destinations. Optimizing the transmission of each source–destination pair is interrelated with that of the other pairs, and characterizing the performance limits of these networks is a challenging task. LÄS MER

3. 7. Design, analysis and simultion for optical access and wide-area networks

   Författare :Jiajia Chen; Lena Wosinska; Hussein Mouftah; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber access networks; passive optical network; dynamic bandwidth allocation; reliability; switched optical networks; switching node; optical circuit switching; optical packet switching; routing and wavelength assignment; security; Telecommunication; Telekommunikation;

   Sammanfattning : Due to the tremendous growth of traffic volume caused by both exponential increase of number of Internet users and continual emergence of new bandwidth demanding applications, high capacity networks are required in order to satisfactorily handle the extremely large amount of traffic. Hence, optical fiber communication is the key technology for the network infrastructure. LÄS MER

4. 8. Metadata Management in Multi-Grids and Multi-Clouds

   Författare :Daniel Espling; Erik Elmroth; Erwin Laure; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; grid computing; cloud computing; accounting; billing; metadata; monitoring; structure; fairshare; scheduling; federated; Computer Science; datalogi;

   Sammanfattning : Grid computing and cloud computing are two related paradigms used to access and use vast amounts of computational resources. The resources are often owned and managed by a third party, relieving the users from the costs and burdens of acquiring and managing a considerably large infrastructure themselves. LÄS MER

5. 9. Performance Aspects of Databases and Virtualized Real-time Applications

   Författare :Christine Niyizamwiyitira; Lars Lundberg; Mikael Svahnberg; Richard Chbeir; Blekinge Tekniska Högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SQL and NoSQL database; Bigdata management systems; Structured and non-structured Database Evaluation; Voice-driven web; Multicore performance prediction; Hard real-time Scheduling; Virtual Multiprocessor Scheduling;

   Sammanfattning : Context: High computing system performance depends on the interaction between software and hardware layers in modern computer systems. Two strong trends that effect different layers in computer systems are that single processors are now more or less completely replaced by multiprocessors, which are often organized into clusters, and virtualization of resources.

7. 10. Techniques to Improve Energy Efficiency on Heterogeneous Multiprocessors under Timing and Quality Constraints

   Författare :Muhammad Waqar Azhar; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thread throttling; Energy Efficiency; Dynamic Voltage Frequency Scaling DVFS ; Quality of Service; Heterogeneous multiprocessor; Soft real time systems.; Resource management; Core migration;

   Sammanfattning : Traditionally, applications are executed without the notion of a computational deadline and often use all available system resources, which leads to higher energy consumption. User specification of Quality of Service (QoS) constraints, in terms of completion time and solution quality, opens up for allocation of just enough resources to an application to finish just in time and thereby save energy.
