  1. 1. Influence of Varying Electric Light Distribution on Melanopic Equivalent Daylight Illuminance and Lighting Energy Use

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Rebecka Ståhl; Parvathy Biju; [2023]
    Keywords : Alertness; Circadian Entrainment; Clear Sky; Correlated Colour Temperature; Daylighting; Direct Electric Lighting; Direct-Indirect Electric Lighting; Energy-Efficiency; Grasshopper; Integrative Lighting; LARK 2.0; Melanopic Equivalent Daylight Illuminance; Overcast Sky; Photopic Illuminance; Spectral Power Distribution.; Technology and Engineering;

    Abstract : Human beings in modern society spend more than 90% of their time indoors to live, work, and socialize. To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. READ MORE

  3. 2. Borderland Peripheries. from dead end - to new beginning

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Maya Kranner; [2023]
    Keywords : Rural renewal; cross-border initiatives; periphery; social sustainability; Arts and Architecture;

    Abstract : It’s been 34 years ago now since the iron curtain has parted the European continent and its inhabitants in an East and a West. The analysed area for the following thesis on the border between northern Austria and southern Czechia gives a case example of a region, that is still suffering from an era, where one sky-direction has been erased from people’s everyday living and thinking – leaving the border areas as a dead end for either country.

  4. 3. 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

  5. 4. Energy and Circadian Assessment of a Combination Between Integrative Lighting and Daylight Harvesting

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Ribhi Attar; Omar Al Mawla; [2021]
    Keywords : ALFA; Circadian Entrainment; Correlated Colour Temperature; Cortisol; Daylighting; Daylight Harvesting; Energy efficiency; Integrative lighting; Intrinsically photosensitive retinal ganglion cells; Melatonin; Melanopic Lux; Photopic Lux; Spectral Power Distribution; Technology and Engineering;

    Abstract : This study deals with the health and wellbeing of humans who work in offices as well as the energy use for the lighting. The focus is on how integrative lighting and daylight harvesting can be combined in an attempt to reduce the energy consumption while still eliciting a circadian response for the workers. READ MORE

  6. 5. Ultraluminous sources in X-ray sky surveys

    University essay from Uppsala universitet/Högenergifysik

    Author : Miquel Colom i Bernadich; [2020]
    Keywords : X-rays; X-ray astronomy; black holes; neutron stars; accretion physics; XMM-Newton; eROSITA;

    Abstract : Ultraluminous X-ray sources (ULXs) are extragalactic, non-nuclear, point-like X-ray sources whose luminosity supersedes that of the Eddington limit of an accreting stellar mass black hole (L> 10 ^ 39 erg / s). Most of them are powered by black holes and neutron stars undergoing genuine super-Eddington accretion, with a small handful of candidates being consistent with sub-Eddington accretion on an intermediate mass black hole.
