1. 16. Falsification of Signal-Based Specifications for Cyber-Physical Systems

   Författare :Johan Lidén Eddeland; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation-Based Verification; Testing; Falsification; Cyber-Physical Systems;

   Sammanfattning : In the development of software for modern Cyber-Physical Systems, testing is an integral part that is rightfully given a lot of attention. Testing is done on many different abstraction levels, and especially for large-scale industrial systems, it can be difficult to know when the testing should conclude and the software can be considered correct enough for making its way into production.

3. 17. Runtime Management of Multiprocessor Systems for Fault Tolerance, Energy Efficiency and Load Balancing

   Författare :Stavros Tzilis; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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.

4. 18. Aircraft Systems Conceptual Design : An object-oriented approach from to

   Författare :Ingo Staack; Petter Krus; Frank Thielecke; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Aircraft Conceptual Design (ACD) is facing new challenges on the way to enhanced fidelity level required of the nowadays complex system design. Namely the integration of models and simulations of different fidelity levels to enhance the analysis capability while maintaining a streamlined, transparent, and low cost working process is required.

5. 19. High Performance Hybrid Memory Systems with 3D-stacked DRAM

   Författare :Evangelos Vasilakis; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DRAM caches; Data migration; 3D-stacked DRAM; Hybrid memory systems;

   Sammanfattning : The bandwidth of traditional DRAM is pin limited and so does not scale well with the increasing demand of data intensive workloads. 3D-stacked DRAM can alleviate this problem providing substantially higher bandwidth to a processor chip. LÄS MER

7. 20. Implementation Methodology in Action : A Study of an Enterprise Systems Implementation Methodology

   Författare :Daniela Mihailescu; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Enterprise Systems; implementation methodology; AcceleratedSAP; Implementation methodology; Action framework; Software engineering; Programvaruteknik; Economic Information Systems; Ekonomiska informationssystem; Informatics;

   Sammanfattning : Enterprise Systems create new opportunities but also new challenges and difficulties for implementers and users. The clear distinction between the development and the implementation of Enterprise Systems Software seems to influence not only the characteristics of methodologies but also how implementers use the Enterprise Systems implementation methodologies.
