1. 11. Synchrophasor Applications and their Vulnerability to Time Synchronization Impairment

   Författare :Muhammad Shoaib Almas; Luigi Vanfretti; Mario Paolone; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hardware-in-the-loop; phasor measurement units; real-time simulation; time synchronization; wide-area monitoring protection and control.; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Recent years have seen the significance of utilizing time-synchronized, high resolution measurements from phasor measurement units (PMUs) to develop and implement wide-area monitoring, protection and control (WAMPAC) systems. WAMPAC systems aim to provide holistic view of the power system and enable detection and control of certain power system phenomena to enhance reliability and integrity of the grid. LÄS MER

3. 12. Towards Large-Capacity and Cost-Effective Main Memories

   Författare :Dmitry Knyaginin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fairness; Energy Efficiency; Hybrid Main Memory; Performance; Design-Space Exploration; Parallel Memory Protocols; Large-Capacity Local Memory; Hardware-Based Hybrid Memory Management; Cost-Effectiveness;

   Sammanfattning : Large, multi-terabyte main memories per processor socket are instrumental to address the continuously growing performance demands of domains like high-performance computing, databases, and big data. It is an important objective to design large-capacity main memories in a way that maximizes their cost-effectiveness and at the same time minimizes performance losses caused by cost-effective tradeoffs.

4. 13. Power and Performance Optimization for Network-on-Chip based Many-Core Processors

   Författare :Yuan Yao; Zhonghai Lu; Trevor E. Carlson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Many-Core Processor; Network-on-Chip; Performance; Power Management; DVFS; Shared Memory Synchronization; Hardware Software Co-Design; Cache Coherency; Performance Isolation; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Network-on-Chip (NoC) is emerging as a critical shared architecture for CMPs (Chip Multi-/Many-Core Processors) running parallel and concurrent applications. As the core count scales up and the transistor size shrinks, how to optimize power and performance for NoC open new research challenges. LÄS MER

5. 14. Functional product development : an explorative view

   Författare :Åsa Ericson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funktionella produkter; Functional Product Development; Computer Aided Design; Datorstödd maskinkonstruktion;

   Sammanfattning : Embodied in the concept of functional products is a shift in view for manufacturing companies as providers of physical artefacts to service providers. Furthermore, differentiation by offering added value, increased commitment towards customers, life-cycle commitment for the physical artefact and close collaboration between manufacturing companies are characteristics of the concept of functional products.

7. 15. Haptic Feedback Control Methods for Steering Systems

   Författare :Tushar Chugh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passivity and coupled stability; torque and position overlay; Haptic feedback; impedance and admittance control; system identification; steering system;

   Sammanfattning : Haptic feedback from the steering wheel is an important cue that defines the steering feel in the driver-vehicle interaction. The steering feedback response in an electric power assisted steering is primarily dependent on its control strategy. LÄS MER
