1. 1. Ray Tracing Algorithm for Dielectric Domes

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Maria Pubill; [2023]
   Keywords : Array antenna; dielectric dome; Ray-Tracing; reflection; absorption losses; matching layers; Arrayantenn; dielektrisk kupol; strålföljning; reflektion; absorptionsförluster; anpassningsskikt;

   Abstract : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. READ MORE

3. 2. Techno-economic Analysis and Market Potential Study of Solar Heat in Industrial Processes : A Fresnel Direct Steam Generation case study

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Guillermo de Santos López; [2021]
   Keywords : Solar heat in industrial processes; techno-economic analysis; market potential; direct steam generation; Fresnel technology;

   Abstract : The industrial sector not only has a big contribution to global emissions but also a low share of renewable energy for heat demand. Knowing that most of the energy consumption in industry is heat and that half of it is at medium-low temperature (below 400 ºC), it is a great market for the integration of solar thermal technologies.

4. 3. Understanding the Optical Principles of UV-based Antifouling

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Partikel- och kärnfysik

   Author : Erik Wilson; [2018]
   Keywords : Technology and Engineering;

   Abstract : In 2014 Salters et. al. introduced the concept of an UV-emitting wallpaper. By using UVC LEDs, a completely clean ship hull surface can be achieved without polluting the marine environment with biocides, normally associated with antifouling paints. READ MORE

5. 4. Development and application of a multidomaindynamic model for direct steamgeneration solar power plant

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Anthony Rousset; [2017]
   Keywords : Concentrated Solar Power CSP ; Direct Steam Generation DSG ; dynamic modelling; co-simulation; thermal-hydraulic calculation; two-phase flow; Ledinegg instabilities; control-command; regulation; PID controller.; Koncentrerad solenergi CSP ; Direkt ånggenerering DSG ; dynamisk modellering; co-simulering; termisk hydraulisk beräkning; tvåfasflöde; Ledinegg instabiliteter; kontrollkommando; reglering; PID-kontroller..;

   Abstract : Nowadays, one of the solutions considered in order to face the issue of global warming and to move towards a carbon neutral society relies on the use of solar energy as a renewable and bountiful primary source. And, if photovoltaic technologies account for a large part in the solar energy market, recent years have witnessed the growth of non-concentrated and concentrated solar thermal technologies.
