  1. 11. Dual Data Rate Network-on-Chip Architectures

    Författare :Ahsen Ejaz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dual Data-Rate; Network-on-Chip; System-on-Chip; On-Chip Interconnect; Chip Multiprocessors; Multiprocessor System-on-Chip;

    Sammanfattning : Networks-on-Chip (NoCs) are becoming increasing important for the performance of modern multi-core systems-on-chip. The performance of current NoCs is limited, among others, by two factors: their limited clock frequency and long router pipeline. The clock frequency of a network defines the limits of its saturation throughput. LÄS MER

  3. 12. Time and Frequency Transfer using Passive Techniques in Active Fiber Optic Networks

    Författare :Sven-Christian Ebenhag; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber link; optical fiber.; Global positioning system GPS ; fiber network; time transfer; two-way; synchronous optical networking SONET synchronous digital hierarchy SDH ; GPS carrier phase;

    Sammanfattning : For the modern society, high precision time and frequency transfer have become crucial since a large number of systems, such as telecommunication systems, require precise and stable synchronization. Electric power companies use synchronized systems for taking stability measurements and searching for errors in their networks. LÄS MER

  4. 13. Uncertainty quantification for high frequency waves

    Författare :Gabriela Malenova; Olof Runborg; Daniel Appelö; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We consider high frequency waves satisfying the scalar wave equationwith highly oscillatory initial data. The speed of propagation of the mediumas well as the phase and amplitude of the initial data is assumed to beuncertain, described by a finite number of independent random variables withknown probability distributions.

  5. 14. Sensor Data Sharing in V2X Communications : Protocol Design and Performance Optimization of Collective Perception

    Författare :Quentin Delooz; Andreas Festag; Alexey Vinel; Maben Rabi; Ana Aguiar; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; V2X; sensor data sharing; vehicular communications; Collective Perception; data congestion; Decentralized Congestion Control;

    Sammanfattning : Sensor data sharing involves exchanging sensor data among multiple devices, systems, or platforms through various means, such as wired or wireless communication, cloud storage, and distributed computing. In Vehicle-to-Everything (V2X) communication, sensor data sharing is known as Collective Perception (CP). LÄS MER

  7. 15. Uncertainty quantification for high frequency waves

    Författare :Gabriela Malenova; Olof Runborg; Fabio Nobile; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : We consider high frequency waves satisfying the scalar wave equation with highly oscillatory initial data represented by a short wavelength ε. The speed of propagation of the medium as well as the phase and amplitude of the initial data is assumed to be uncertain, described by a finite number of independent random variables with known probability distributions.
