  1. 1. Exploring the Possibilities of 14C Bomb-Pulse Dating of Human Tissue Samples

    Författare :Elisavet Georgiadou; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 14C measurements; Bomb-pulse dating; human body; serum; plaque; Fysicumarkivet A:2014:Georgiadou;

    Sammanfattning : The testing of nuclear weapons in the atmosphere, in the middle of the 20'h century, resulted in a bomb-pulse excess of atmospheric 14C. A bomb-pulse dating method was thus developed. The latter is a method to determine the time of formation of formerly living modern (i.e. LÄS MER

  3. 2. Methods of Multi-Conjugate Adaptive Optics for Astronomy

    Författare :Ralf Flicker; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adaptive optics; anisoplanatism; laser guide stars; performance estimation; wavefront reconstruction; extremely large telescopes; optics; Electromagnetism; Elektromagnetism; acoustics; Astronomy; akustik; space research; optik; multi-conjugate; cosmic chemistry; Astronomi; rymdvetenskap; kosmisk kemi; Fysicumarkivet A:2003:Flicker;

    Sammanfattning : This work analyses several aspects of multi-conjugate adaptive optics (MCAO) for astronomy. The research ranges from fundamental and technical studies for present-day MCAO projects, to feasibility studies of high-order MCAO instruments for the extremely large telescopes (ELTs) of the future.

    Sammanfattning : An overview of the state of art within optical design of large astronomical telescopes is given. Recent advances within the field are presented. The importance of new computer-controlled mirror-polishing methods is emphasized. LÄS MER

  5. 4. Spectral Control of Functional Fiber Sources

    Författare :Robert Lindberg; Valdas Pasiskevicius; Stefano Taccheo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optics and Photonics; Optik och fotonik;

    Sammanfattning : This thesis is based on five projects aimed at spectral control of fiber-based laser architectures. Two of these concern electrically wavelength-tunable laser sources, namely a fiber amplifier system for CO2-monitoring and a novel tunable laser design for flexible pulsed operation. LÄS MER
