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

   Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Författare :Rebecka Ståhl; Parvathy Biju; [2023]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Turning Night into Day : Does Skyglow affect Bat Activity and Timing of Emergence?

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Torge Gerwin; [2023]
   Nyckelord :Skyglow; Bats; Light pollution; Bat activity; Bat emergence; Riparian forest; Landscape composition; Multi-scale landscape; Landscape management; Sweden;

   Sammanfattning : Artificial brightness of the night sky caused by the backscatter of artificial light in the atmosphere is a consequence of ongoing urbanization. Skyglow covers 88 % of Europe’s surface and poses significant threats to biodiversity. Extensive research on responses of bats to direct light pollution already revealed significant impacts. LÄS MER

4. 3. The ecological impact of artificial light at night in landscape architecture : strategies and guidelines for street lights for the benefit of biodiversity and local wildlife

   Kandidat-uppsats, SLU/Dept. of Urban and Rural Development

   Författare :Zozan Altun; [2023]
   Nyckelord :light pollution; artificial light at night; ecology; biodiversity; local wildlife; landscape architecture; guidelines; strategies;

   Sammanfattning : Artificial light at night (ALAN) is an increasingly common form of light pollution that contributes to biodiversity loss, loss of dark habitats, disrupting populations both on an individual- and population level by invading biodiversity hot spots. Recent studies show that artificial light is increasing at a rate of approximately 6% annually over Earth’s surface, and 88% of Europe and 47% of the United States experience light pollution on a nightly basis.

5. 4. Den mörka sidan av ljuset

   Master-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Författare :Cornelia Flemming; [2023]
   Nyckelord :Safety; Street light; Light pollution; ALAN; Biodiversity; The City of Helsingborg; Municipality; Earth and Environmental Sciences;

   Sammanfattning : The spread of artificial light on Earth increases annually. One of many causes of this spread is due to increased street lighting and artificial light at night (ALAN). Lighting is one of the many necessities for people to feel safe. LÄS MER

7. 5. Classification and localization of extreme outliers in computer vision tasks in surveillance scenarios

   M1-uppsats, KTH/Hälsoinformatik och logistik

   Författare :Tariq Daoud; Emanuel Zere Goitom; [2022]
   Nyckelord :Computer vision; deep learning; machine learning; artificial neural networks; convolutional neural networks; YOLOv4; Datorseende; djupinlärning; maskininlärning; artificiella neurala nätverk; konvolutionella neurala nätverk; YOLOv4;

   Sammanfattning : Convolutional neural networks (CNN) have come a long way and can be trained toclassify many of the objects around us. Despite this, researchers do not fullyunderstand how CNN models learn features (edges, shapes, contours, etc.) fromdata. LÄS MER
