1. 1. EMC-Optimized Transparency: Reducing Electromagnetic Emissions in Surveillance Camera Domes

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Fabian Sondh; Erik Hansson; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Electromagnetic compatibility (EMC) is a crucial aspect to product development. Companies need to make sure their products live up to the standards that exists around the world. One way of reducing electromagnetic emissions is to shield the product, using some conducting material, for instance, copper. LÄS MER

3. 2. Use of Satellite Remote Sensing for Detecting Archaeological Features: An Example from Ancient Corinth, Greece

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Emmanouil Papadakis; [2023]
   Nyckelord :Geography; GIS; Satellite Remote Sensing; Vegetation Indices; Classification; Archaeology; Earth and Environmental Sciences;

   Sammanfattning : During the last few decades, satellite remote sensing has proven to be an important non-invasive method for archaeological research in order to detect ancient sites and manage existing ones. Archaeologists have tried in the recent past to embed Geographic Information Systems (GIS) and image processing techniques in their research as non-destructive approaches, which can allow a wider perception of archaeological landscapes and predict past behaviors.

4. 3. Impact of nanoparticle plasmons on photoluminescense and upconversion processes in ZnO

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik; Uppsala universitet/Fysikalisk kemi

   Författare :Axel Gudmundsson; [2023]
   Nyckelord :Photoluminescence; Upconversion; Plasmons; ZnO;

   Sammanfattning : The increasing prevalence of glass windows in modern buildings has raised the demand for solar control windows that possess climate-appropriate properties. Glass windows made of abundant and low-cost materials which can both decrease the heating energy consumption as well as enhance the light climate indoors would sufficiently meet the goals of economical yet uplifting buildings.

5. 4. Simulations of the Tenuous Upper Atmospheres of Exoplanets

   Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Författare :Lucian Spitzner; [2023]
   Nyckelord :astronomy; astrophyics; exoplanets; transmission spectroscopy; magnetic fields; atmospheres; ions; Physics and Astronomy;

   Sammanfattning : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. LÄS MER

7. 5. Water born cooling of closed greenhouses : An enclosed vertical water curtain cooling system

   Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Ahmad Kamal; [2022]
   Nyckelord :Greenhouses; Water born cooling; Enclosed water curtain; radiative cooling; Surplus heat energy;

   Sammanfattning : The greenhouses play a key role in food sustainable production, the purpose of the greenhouses is to make an artificial suitable environment to grow different kinds of plants. The cost of energy used in the greenhouses to ensure the optimum temperature, humidity, and CO2 concentration, makes up a large part of the final cost of food. LÄS MER
