  1. 16. Optimization of Rotations in FFTs

    Författare :Fahad Qureshi; Oscar Gustafsson; Mario Garrido; Jarmo Takala; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete Fourier transform; Fast Fourier transform; twiddle factor multiplication;

    Sammanfattning : The aims of this thesis are to reduce the complexity and increasethe accuracy of rotations carried out inthe fast Fourier transform (FFT) at algorithmic and arithmetic level.In FFT algorithms, rotations appear after every hardware stage, which are alsoreferred to as twiddle factor multiplications.

  3. 17. Performance Optimization Techniques and Tools for Data-Intensive Computation Platforms : An Overview of Performance Limitations in Big Data Systems and Proposed Optimizations

    Författare :Vasiliki Kalavri; Vladimir Vlassov; Alberto Montresor; KTH; []
    Nyckelord :performance optimization; data-intensive computing; big data; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Big data processing has recently gained a lot of attention both from academia and industry. The term refers to tools, methods, techniques and frameworks built to collect, store, process and analyze massive amounts of data. Big data can be structured, unstructured or semi-structured.

  4. 18. Offline Task Scheduling in a Three-layer Edge-Cloud Architecture

    Författare :Ayeh Mahjoubi; Karl-Johan Grinnemo; Arunselvan Ramaswamy; Alessandro Papadopoulos; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; task offloading; task scheduling; edge computing; internet of things; optimization techniques; heuristics; meta-heuristics; Computer Science; Datavetenskap;

    Sammanfattning : Internet of Things (IoT) devices are increasingly being used everywhere, from the factory to the hospital to the house to the car. IoT devices typically have limited processing resources, so they must rely on cloud servers to accomplish their tasks. Thus, many obstacles need to be overcome while offloading tasks to the cloud.

  5. 19. On Experimentation in Software-Intensive Systems

    Författare :David Issa Mattos; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; Automated Experimentation; Experimentation process; Multi-armed bandits; Embedded Systems; Experimentation;

    Sammanfattning : Context: Delivering software that has value to customers is a primary concern of every software company. Prevalent in web-facing companies, controlled experiments are used to validate and deliver value in incremental deployments. LÄS MER

  7. 20. Design of Assured and Efficient Safety-critical Systems

    Författare :Nesredin Mahmud; Cristina Seceleanu; Guillermo Rodriguez-Navas; Joost-Pieter Katoen; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems design; safety critical systems; real time systems; formal method; optimization; model checking; Simulink; Computer Science; datavetenskap;

    Sammanfattning : Safety-critical   systems   need   to   be   analyzed rigorously to remove software/specifications errors, that is, their requirements specifications should be unambiguous, comprehensible and consistent, and the software design should conform to the specifications, hence avoiding undesirable system failures. Currently, there is a lack of effective and scalable methods to specify and analyze requirements, and formally analyze the behavioral models of embedded systems. LÄS MER
