21. Single Photon LSCM in the NIR Range
Master-uppsats, KTH/Tillämpad fysikSammanfattning : In this thesis a near-infrared laser scanning confocal microscope (NIR-LSCM) is built to operate with optimal performance at 1550nm in combination with simultaneous LED light imaging at 970nm. For detection, a camera equipped with a complementary metal oxide semiconductor (CMOS) sensor and a superconducting nanowire single photon detector (SNSPD) are used for the LED part and the LSCM part, respectively.

22. Antenna as a sensor for sensing available LTE networks
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
23. Collective PV nano-grid for households in Linga Linga : A Minor Field Study in Mozambique
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : 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.

24. Developing complementary supercritical fluid chromatographic methods for a high throughput purification process
Master-uppsats, Karlstads universitetSammanfattning : 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. LÄS MER
25. Indoor VLC behaviour with RGB spectral power distribution using simulation.
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskapSammanfattning : 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. LÄS MER
