  1. 1. Fault Isolation in Distributed Embedded Systems

    Författare :Jonas Biteus; Erik Frisk; Jan Eric Larsson; Linköpings universitet; []
    Nyckelord :Fault diagnosis; Fault isolation; Distributed diagnosis; Embedded systems; Fault tree analysis.; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : To improve safety, reliability, and efficiency of automotive vehicles and other technical applications, embedded systems commonly use fault diagnosis consisting of fault detection and isolation. Since many systems are constructed as distributed embedded systems including multiple control units, it is necessary to perform global fault isolation using for example a central unit. LÄS MER

  3. 2. Learning Behavior Trees for Collaborative Robotics

    Författare :Matteo Iovino; Christian Smith; Karinne Ramírez-Amaro; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Collaborative Robotics; Behavior Trees; Datalogi; Computer Science;

    Sammanfattning : This thesis aims to address the challenge of generating task plans for robots in industry-relevant scenarios. With the increase in small-batch production, companies require robots to be reprogrammed frequently for new tasks. However, maintaining a team of operators with specific programming skills is only cost-efficient for large-scale production. LÄS MER

  4. 3. Behavior Trees in Robotics

    Författare :Michele Colledanchise; Petter Ögren; Dimos Dimarogonas; Yiannis Karayiannidis; Dana Nau; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datalogi;

    Sammanfattning : Behavior Trees (BTs) are a Control Architecture (CA) that was invented in the video game industry, for controlling non-player characters. In this thesis we investigate the possibilities of using BTs for controlling autonomous robots, from a theoretical as well as practical standpoint. LÄS MER

  5. 4. Analysis of enterprise IT service availability : Enterprise architecture modeling for assessment, prediction, and decision-making

    Författare :Ulrik Franke; Pontus Johnson; Lars Nordström; Göran Ericsson; João Paulo A. Almeida; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Service Level Agreement; outage costs; Enterprise Architecture; enterprise IT service availability; decision-making; metamodeling; Enterprise Architecture analysis; Bayesian networks; fault trees; Predictive Probabilistic Architecture Modeling Framework; Service Level Agreement; nertidskostnader; Enterprise Architecture; tillgänglighet hos IT-tjänster; beslutsfattande; metamodellering; arkitekturanalys; bayesianska nätverk; felträd; Predictive Probabilistic Architecture Modeling Framework;

    Sammanfattning : Information technology has become increasingly important to individuals and organizations alike. Not only does IT allow us to do what we always did faster and more effectively, but it also allows us to do new things, organize ourselves differently, and work in ways previously unimaginable.

  7. 5. Development and application of high voltage dielectric spectroscopy for diagnosis of medium voltage XLPE cables

    Författare :Peter Werelius; KTH; []
    Nyckelord :dielectric spectroscopy; high voltage; variable frequency; diagnostics; non-disgnostics;

    Sammanfattning : When polymer power cables were introduced into mediumvoltage applications in the late 1960s, the degradationphenomenon later referred to aswater treeingwas still unknown. However, this changedwithin a relatively short space of time. LÄS MER
