  1. 1. Reliability-centred maintenance : identification of management and organisational aspects when introducing RCM

    Författare :Fredrik Backlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

    Sammanfattning : Increased demands on productivity, quality and cost-efficiency affecting manufacturing trends towards increased complexity and higher degree of process automation. A major break down in such a manufacturing system may generate severe damage on productivity, environment and personnel. LÄS MER

  3. 2. Flip chip for high frequency applications : materials aspects

    Författare :Katarina Boustedt; Dag Stranneby; Rao Tummala; Örebro universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flip chip; underfill; bumping; microwave; gallium arsenide; high frequency; thermocompression; soldering; stud bumps; coplanar waveguide; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Elektronik; Electronics;

    Sammanfattning : Flip chip has since decades been the primary choice for chip interconnect for high performance circuits. Over the last few years, interest from the microwave arena has increased, and at this point in time microwave flip chip is a possible option for volume production. LÄS MER

  4. 3. Maintenance-related incidents and accidents : aspects of hazard identification

    Författare :Mattias Holmgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : The satisfaction of stakeholders depends upon the fulfilment of their requirements. Two important stakeholder requirements related to technical systems are dependability and safety. However, system operation will gradually impair its performance leading to potentially hazardous states of the system. LÄS MER

  5. 4. Fatigue and Fracture of High-Strength Steels : Improving Reliability in Strength Assessment

    Författare :Gustav Hultgren; Zuheir Barsoum; Rami Mansour; Torbjörn Narström; Gary Marquis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-Strength Steel; Quality assurance; Probabilistic modeling; Fatigue; Fracture mechanics; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Structural steel plays a fundamental role in the heavy industry, serving as a key material for numerous load-bearing products and equipment. Its widespread use is attributed to its robustness, resistance to wear, ease of use in construction, and cost-effectiveness. LÄS MER

  7. 5. Projective methods and longitudinal developmental research : considerations of data's nature and reliability

    Författare :Harald Janson; Bertil Mårdberg; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Longitudinal studies; projective methods; reliability; temporal stability; interrater agreement; epistemology; measurement; psykologi; Psychology;

    Sammanfattning : A projective method is viewed in the present work as a psychological test, by which is understood a standardized task that is set before a person, the solution of which is used for making inferences about psychological quantities. The present research was designed to shed light on several aspects of the usefulness of projective methods in longitudinal research, particularly with regard to reliability and to the distinction between measurement and theory-free empirical-comparison data.
