  1. 21. Antenna as a sensor for sensing available LTE networks

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

    Author : Barath Kumar Sathish Kumar; [2022]
    Keywords : Radio Frequency energy harvesting; Antenna as a sensor; Long-Term Evolution; Rectifier; Printed Circuit Board; Altium Designer; Matching network; Voltage multiplier; Schottky diodes; Multiband LTE antenna; Ambient energy harvesting; Low power Internet of Things; Wireless power transfer; Radiofrekvensenergiskörd; Antenn som sensor; LTE; Likriktare; Printed Circuit Board; Altium Designer; Matchande nätverk; Spänningsmultiplikator; Schottky-dioder; Multiband LTE-antenn; Omgivande energiskörd; Lågeffekt Internet of Things; Trådlös kraftöverföring;

    Abstract : This thesis primarily deals with the concept of designing an antenna based device to harvest energy from Radio Frequency (RF) and using the harvested energy to sense the available Long Term Evolution (LTE) network in order for the Internet of Things (IoT) devices to connect to the network for the purpose of transmitting and receiving data. Secondarily the importance of this project is targeting how to conserve battery power in an IoT device and extend it’s lifetime. READ MORE

  3. 22. Collective PV nano-grid for households in Linga Linga : A Minor Field Study in Mozambique

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

    Author : Wilma Diaz Hjelm; Ellie Olsson; [2022]
    Keywords : Collective Energy System; Solar PV system; Electricity Accesses; off-grid; nano-grid; Rural Mozambique; Minor Field Study; Project Vita; Kollektivt Energisystem; Solcellssystem; Tillgång till Elektricitet; Nano-Nät; Moçambiques Landsbygd; Minor Field Study; Project Vita;

    Abstract : About a third of Mozambique’s population has access to electricity, and the same number in rural areas, where most of the population lives, is down to 5 %. Small-sized off-grid solutions are economical alternatives to increase the electricity access rate in rural areas, and solar power is a common energy source due to price and weather conditions.

  4. 23. Developing complementary supercritical fluid chromatographic methods for a high throughput purification process

    University essay from Karlstads universitet

    Author : Alma Söderström; [2022]
    Keywords : Supercritical Fluid Chromatography; Pharmaceutical Industry; Column screening; Green chemistry; Superkritisk vätskekromotografi; Läkemedelsindustri; Kolonn set; Grön kemi;

    Abstract : Supercritical fluid chromatography (SFC) is an expanding chromatographic technique that is part of the evolving field of green chemistry due to its short run times and use of non-toxic solvents in combination with recycled CO2. The use of a suitable column is essential for separation science in general and there is a wide variety of SFC compatible columns available on the market. READ MORE

  5. 24. Indoor VLC behaviour  with RGB spectral power distribution using simulation.

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Siva Babu Ajjapu; Sasank Reddy Lokireddy; [2021]
    Keywords : ;

    Abstract : n recent years visible light communication (VLC) has been one of the technologies overgrowing in this competitive world and breaking through the wireless transmission of future mobile communications. This VLC replaces radio frequency (RF), which has several important features like large bandwidth, low cost, unlicensed spectrum. READ MORE

  6. 25. Investigation of sex-based differences in responses to artificial light of the greater waxmoth (Galleria mellonella)

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Prasoon Singh; [2021]
    Keywords : Light pollution; Galleria mellonella; warm-white light; moths behaviour; attraction;

    Abstract : Artificial light at night (ALAN) is becoming a greater threat to nocturnal species. Aside from the overall increase in light output, replacing outdated monochromatic street lighting with light-emitting diode (LED) lights with a broad emission spectrum could raise this issue more.
