1. 36. 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

3. 37. Detection and Quantification of Variable Viral RNA by Real-Time PCR Assays

   Författare :Shaman Muradrasoli; Jonas Blomberg; Göran Friman; Maria Brytting; Uppsala universitet; []
   Nyckelord :Virology; Diagnosis of Viral RNA; QPCR; RNA virus; broadly targeted PCR; probe design strategy; Infectious diseases; Medicin; Medicine;

   Sammanfattning : As the area of nucleic acid based technologies develops, so will our understanding of how structural variations in DNA and RNA pathogens are associated with disease. The overall goal of this thesis is the development of broadly targeted measurement techniques for variable viral RNA by Real-Time PCR (here referred to as quantitative reverse transcriptase PCR, QRT-PCR).

4. 38. Diagnosability analysis and FDI system design for uncertain systems

   Författare :Daniel Eriksson; Erik Frisk; Mattias Krysander; Alexander Medvedev; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Our society depends on advanced and complex technical systems and machines, for example, cars for transportation, industrial robots in production lines, satellites for communication, and power plants for energy production. Consequences of a fault in such a system can be severe and result in human casualties, environmentally harmful emissions, high repair costs, or economical losses caused by unexpected stops in production lines.

5. 39. Diagnosing faults using knowledge about malfunctioning behavior

   Författare :Tim Hansen; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Second generation expert systems presume support for deep reasoning, i.e. the modelling of causal relationships rather than heuristics only. Such an approach benefits from more extensive inference power, improved reusability of knowledge and a better potential for explanations. LÄS MER

7. 40. Designing for Change in Complex Systems : Design Considerations for Uptime in a Transportation System with Driverless Vehicles

   Författare :Lina Rylander; Jonas Mårtensson; Magnus Eneberg; Josina Vink; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Machine Design; Maskinkonstruktion;

   Sammanfattning : The transportation system is undergoing a transformation to enable socially, environmentally, and economically sustainable transport solutions, and driverless trucks are considered one innovation that can contribute to a more sustainable and efficient transportation system. Nevertheless, introducing driverless trucks will cause disruptions in the system, and one considerable change is that the driver is no longer present. LÄS MER
