  1. 21. On Integrity Monitoring of Integrated Navigation Systems

    Författare :Jan Palmqvist; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In civil aviation a new philosophy for flight safety and traffic management is under development. The goal is to enable an expected increase in air traffic density by reducing aircraft separation. The accuracy of the position estimate determined by the navigation system in each aircraft determines this separation. LÄS MER

  3. 22. Some Aspects of Advanced Technologies and Signal Integrity Issues in High Frequency PCBs, with Emphasis on Planar Transmission Lines and RF/Microwave Filters

    Författare :Felix D. Mbairi; Sture Petersson; Shaofang Gong; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal integrity; crosstalk; guard trace; PCB; transmission line loss; high frequency measurement; dielectric; SU-8; electromagnetic bandgap; microwave filter; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : The main focus of this thesis is placed on high frequency PCB signal Integrity Is-sues and RF/Microwave filters using EBG structures. From the signal Integrity aspect, two topics were mainly discussed. LÄS MER

  4. 23. Structural integrity of prestressed nuclear reactor containments

    Författare :Patrick Anderson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel liner; reliability; relaxation; shrinkage; creep; loss of prestress; tendon; Nuclear; containment; design pressure; Construction technology; Anläggningsteknik;

    Sammanfattning : A nuclear power plant is provided with an extensive defense intended to prevent radioactive discharge in case of a reactor accident. This defense is built up of several independent safety barriers, where the reactor containment constitutes the last barrier to the environment. LÄS MER

  5. 24. Investigating the effect of extending powder particle size distribution of Ti-6Al-4V produced by powder bed fusion laser beam process : Influence of process parameters on material integrity

    Författare :Linda Squillaci; Magnus Neikter; Ru Peng; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powder Bed Fusion Laser Beam PBF-LB ; Ti-6Al-4V; Microstructure; Particle Size Distribution PSD ; Productivity Enhancement; Pulverbädd additiv tillverkning PBF-LB M ; Ti-6Al-4V; Mikrostruktur; Pulverpartikelstorleksfördelning; Produktivitetsförbättring; Production Technology; Produktionsteknik;

    Sammanfattning : This thesis focuses on the topic of PBF-LB applied to titanium alloys. Of allalloys, an α + β is chosen, named Ti-6Al-4V. The selection of this particular alloy is driven by its current widespread use in many industrial applications where high strength coupled with low density are both desirable properties. LÄS MER

  7. 25. The interplay between chromosome structure and meiotic integrity

    Författare :Ingrid Lilienthal; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Sexually reproducing organisms employ a specialized cell division called meiosis to form unique, haploid gametes from a diploid precursor cell. Upon fertilization, two opposite-sex gametes fuse to create a zygote that will develop into the offspring. LÄS MER
