  1. 1. Laboratory starlight simulator for future space-based heterodyne interferometry

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : William Karlsson; [2023]
    Keywords : Angular resolution; Astronomy; Coherence length; Digital delay lines; Fiber optical circuit; Heterodyne interferometry; Interference; Laboratory starlight simulator; NIR light Near-Infrared ; Optical path differences; Space exploration; Starlight; Testbed environment;

    Abstract : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. READ MORE

  3. 2. Bad Bitch, White Witch : A Study of the Crossover Star Personas of Supermodel-Actors Devon Aoki and Abbey Lee

    University essay from Stockholms universitet/Filmvetenskap

    Author : Aléks J. Forsenberg; [2023]
    Keywords : Supermodel-actors; Stardom; Celebrity; Star personas; Devon Aoki; Abbey Lee; Action film; Horror film; Bodily capital; Whiteness; Asian stereotypes; Modelling; Supermodels; Fashion models;

    Abstract : While it is very common for supermodels to make the occasional foray into cinematic performance, and some of them manage to turn these forays into full-time careers in acting, it is very rare that supermodel-actors are afforded any academic attention. This thesis seeks to change this through a case study of two supermodel-actors: Devon Aoki and Abbey Lee. READ MORE

  5. 4. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flow

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Lea Christierson; [2021]
    Keywords : Fluid-structure interaction; paperboard material modeling; transient pipe flow; overset mesh; image analysis; Technology and Engineering;

    Abstract : In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. READ MORE

  6. 5. Seeing Stars - Intensity Interferometry in the Laboratory and on the Ground

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Colin Carlile; [2021]
    Keywords : Stellar Physics Instrumentation Interferometry Cherenkov Telescope Array Intensity Interferometry; Physics and Astronomy;

    Abstract : Context Since the time of Tycho Brahe astronomy has been an observing science defined by the quality of its instrumentation. The introduction of primitive telescopes by Galileo in 1609 began a period of development of ever-larger telescopes with greater measuring precision. READ MORE
