  2. 1. Collaborative, Intelligent, and Adaptive Systems for the Low-Power Internet of Things

    Author : Valentin Poirot; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Networking; Bluetooth Low Energy; Consensus; Low-Power Wireless Networks; TinyML; IoT; Internet of Things; synchronous transmissions;

    Abstract : With the emergence of the Internet of Things (IoT), more and more devices are getting equipped with communication capabilities, often via wireless radios. Their deployments pave the way for new and mission-critical applications: cars will communicate with nearby vehicles to coordinate at intersections; industrial wireless closed-loop systems will improve operational safety in factories; while swarms of drones will coordinate to plan collision-free trajectories.

  4. 2. Runtime Management of Multiprocessor Systems for Fault Tolerance, Energy Efficiency and Load Balancing

    Author : Stavros Tzilis; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.

  5. 3. Graceful Degradation of Adaptive Multiprocessor Systems on a Chip

    Author : Stavros Tzilis; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design space exploration; runtime management; graceful degradation; system optimization; Defect and fault tolerance;

    Abstract : This thesis explores the potential for using existing flexibility in order to allow Multiprocessor Systems on a Chip to function in the presence of permanent faults and to prolong their lifetime. Technology scaling in accordancewith Moore’s law brings up reliability challenges and forces the use of potentially unreliable hardware components. READ MORE

  6. 4. Implementation and Evaluation of Signal Processing Circuits for Optical Communication

    Author : Erik Börjeson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Application-Specific Integrated Circuits; Fiber-Optic Communication; Carrier Phase Recovery; Digital Signal Processing; Communication Systems; Adaptive Equalization;

    Abstract : The digital signal processing (DSP) circuits used in the fiber-optic communication links that make up the backbone of the Internet can be a significant contributor the over-all power dissipation of a link. As the number of connected users and their bandwidth requirements are expected to continue to grow over the coming years, the development of power-efficient high-throughput DSP systems is a critical factor in enabling this growth.
