  3. 12. Radome Diagnostics: utilizing Source Reconstruction based on Surface Integral Representations

    Författare :Kristin Persson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nondestructive testing; source reconstruction; diagnostics; radome; phase reconstruction; insertion phase delay IPD ; equivalent surface currents;

    Sammanfattning : In this thesis, an inverse source reconstruction method with great potential in radome diagnostics is presented. A radome is a cover that encloses an antenna in order to protect it from environmental influences. LÄS MER

  4. 13. Geometric Control of Thrust Propelled Systems

    Författare :Pedro Miguel Ótão Pereira; Dimos V. Dimarogonas; Jana Tumova; Panagiotis Tsiotras; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear control; geometric control; thrust propelled systems; slung load transportation; aerial tethered transportation; control of aerial vehicles; tracking and stabilization; global stabilization; bounded control; disturbance removal; distributed control; attitude synchronization; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis was motivated and inspired by the AEROWORKS project, a European research project, whose main goal was to deploy multiple heterogeneous unmanned aerial vehicles in environments where human intervention is restricted.In particular, this thesis focuses on control of aerial vehicles for the purposes of cargo transportation, an application of interest, for example, in inspection and maintenance of aging infrastructures.

  5. 14. Models for Estimation of Software Faults and Failures in Inspection and Test

    Författare :Per Runeson; Institutioner vid LTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; failures; usage based testing; usage model; statistical testing; faults; capture-recapture; inspections; software quality; software reliability; experiments; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

    Sammanfattning : In software engineering, the quality of software and in particular the software reliability has to be controlled and improved. Hence there is a need for measuring and controlling the number and appearance of software faults and failures. LÄS MER

  7. 15. Modelling intent for Manned-Unmanned Teaming : Exploring human-centric approaches for future combat aircraft systems

    Författare :Jimmy Hammarbäck; Jonas Lundberg; Björn Johansson; Jens Alfredson; Thomas Porathe; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : What does it mean to understand intent? This question is at the core of resilient teamwork since team members must account for each other’s intent in anticipated as well as unanticipated situations to adaptively coordinate their actions. As we enter an era where humans and synthetic agents are supposed to work as teammates, this question is brought to its head. LÄS MER
