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. Lighting Energy Savings in an Office Environment Simulating a Motion Detection Dimming System

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Ida Gutenwik; Nanitza Gonzales Allendes; [2022]
   Keywords : Motion Detection Dimming; Wireless Sensor Network; Energy Consumption; Daylight-Linked Control System; Rörelsedetekterande Dimmers; Trådlöst Sensornätverk; Energikonsumption; Dagsljus-Kopplade Kontrollsystem;

   Abstract : Shortages of electricity in larger cities in Sweden are becoming more common and might increase with an increased consumption. The thesis focuses on lights due to approximately 19 - 20% of the total electricity consumption coming from lights. READ MORE

4. 3. Analyzing the dust of the Nearby Universe

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Jimmy Kjellqvist; [2021]
   Keywords : Intergalactic dust; cosmology; cosmological measurements; quasars; Intergalaktiskt stoft; kosmologi; kosmologiska mätningar; kvasarer;

   Abstract : The aim of this master thesis is to investigate the influence of intergalactic duston astronomical observations. The current cosmological paradigm of an acceleratingcosmic expansion is supported by observations of Type Ia supernovae. READ MORE

5. 4. Foundation for an analysis of the dust of theNearby Universe

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Jimmy Kjellqvist; [2021]
   Keywords : Intergalacitc dust; dust distribution; cosmology; cosmological measurements; quasars;

   Abstract : The current cosmological paradigm of an accelerating cosmic expansion issupported by observations of Type Ia supernovae. However, the light emittedby these and other cosmological sources is not only redshifted by cosmicexpansion but will also interact with matter along the light path. READ MORE

6. 5. May there be light : A study of optimising public lighting in park spaces for energy efficiency and subjective factors

   University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

   Author : Hjalmar Lind; Theodor Ahrenius; [2021]
   Keywords : public lighting; control; control system; simulation; LED; optimising; belysning; stadsbelysning; kontrollsystem; styrsystem; simulering; optimering;

   Abstract : Public lighting is an important part of city infrastructure. In parks, it enables activity, transportation and recreation in the darker hours. As the field of city lighting is rapidly expanding and advancing, innovations like customisable luminaries and LED light source options are making their way into the fray. READ MORE
