3. 2. Design Optimization in Industrial Robotics : Methods and Algorithms for Drive Train Design

   Författare :Marcus Pettersson; Johan Ölvander (Andersson); Torgny Brogårdh; Jorge Angeles; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robot manufacturers; industrial robot; robot design; Electrical engineering; Elektroteknik;

   Sammanfattning : Robot manufacturers, like many other manufacturers, are experiencing increasing competition in a global market where one way to confront the challenge is by making the development process more efficient. One way to speed up the time to market for new products is to take advantage of design optimization based on simulation models. LÄS MER

4. 3. Towards an Ontology Design Pattern Quality Model

   Författare :Karl Hammar; Kurt Sandkuhl; Henrik Eriksson; Vladimir Tarasov; Eva Blomqvist; Arianit Kurti; Jönköping University; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ontology; OWL; Ontology Design Pattern; Semantic Web; Quality Model;

   Sammanfattning : The use of semantic technologies and Semantic Web ontologies in particular have enabled many recent developments in information integration, search engines, and reasoning over formalised knowledge. Ontology Design Patterns have been proposed to be useful in simplifying the development of Semantic Web ontologies by codifying and reusing modelling best practices. LÄS MER

5. 4. Workload characterization, controller design and performance evaluation for cloud capacity autoscaling

   Författare :Ahmed Ali-Eldin Hassan; Erik Elmroth; Johan Tordsson; Prashant Shenoy; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloud computing; autoscaling; workloads; performance modeling; controller design;

   Sammanfattning : This thesis studies cloud capacity auto-scaling, or how to provision and release re-sources to a service running in the cloud based on its actual demand using an auto-matic controller. As the performance of server systems depends on the system design,the system implementation, and the workloads the system is subjected to, we focuson these aspects with respect to designing auto-scaling algorithms.
