  1. 1. Aiding Navigation for Groups of Aircraft with Bearing and Distance Measurements

    University essay from Linköpings universitet/Reglerteknik

    Author : Mattias Olsson; [2018]
    Keywords : Navigational enhancing; consensus filtering;

    Abstract : This thesis extends previous work on navigational aidingof groups of aircraft, primarily intended for the fighter SAAB JAS 39 Gripen,as long as an aircraft gets GPS signals, it is easy to estimate position, but theGPS is relatively easy to jam, rendering alternative methods of positioning necessary.To use internal sensors measuring accelerations and angular velocities is agood replacement on short terms, but gives a drift in positioning over longer timeperiods.

  2. 2. Direct measurement of fluorescence lifetime using high speed data acquisition

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Mattias Olsson; [2018]
    Keywords : Boot-strapped waveform averaging; fluorescence lifetimes; TCSPC; repetitive signal; Technology and Engineering;

    Abstract : Time-correlated single photon counting (TCSPC) is commonly used to measure the lifetime of fluorescence from dye molecules. In TCSPC, the sample is excited by a pulsed laser and the arrival time of each of the emitted photons at the detector relative to a trigger is recorded. READ MORE

  5. 5. A Model-Theoretic Proof of Gödel's Theorem : Kripke's Notion of Fulfilment

    University essay from Stockholms universitet/Matematiska institutionen

    Author : Mattias Granberg Olsson; [2017]
    Keywords : Fulfilment; Gödel s Theorem; Incompleteness;

    Abstract : The notion of fulfilment of a formula by a sequence of numbers, an approximation of truth due to Kripke, is presented and subsequently formalised in the weak arithmetic theory IΣ1, in some detail. After a number of technical results connecting the formalised notion to the meta-theoretical one a version of Gödel’s Incompleteness Theorem, that no consistent, recursively axiomatisable, Σ2-sound extension T of Peano arithmetic is complete, is shown by construction of a true Π2-sentence and a model of T where it is false, yielding its independence from T.
