1. 1. 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. 2. Design and evaluation of ambient RF energy harvesting platform for sensor-based systems : An experimental study of RF energy harvesting

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

   Author : Ibrahim Hamed; [2022]
   Keywords : Radiofrekvensenergiskördning; Trådlös energiskördning; Backscattering-teknik; Programvarudefinierad radio; EMC; PCB; Antenn;

   Abstract : Trådlös energiskörd möjliggör förmågan att skörda energi från elektromagnetisk strålning. Med de senaste framstegen inom trådlös kommunikationsteknik och med tillgången till energieffektiva sensorer, så har radiofrekvensenergiskördning potential till att bli en självförsörjande sensorbaserad plattform.

4. 3. Hybrid Power System for Green Telecom Sites

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

   Author : Giovanni Screpanti; [2021]
   Keywords : ;

   Abstract : Solar Photovoltaic can offer a clean and cheap alternative to the Diesel Generator for telecom sites that are in remote locations with no grid coverage or where the grid is not fully reliable. Ericsson Enclosure & Power is looking into the opportunity to integrate this technology, together with battery storage, into their network sites around the globe, in view of a constantly growing network demand and the diffusion of the 5G technology.

5. 4. Vass som foder till häst och nötkreatur : från skörd till ensilering

   University essay from SLU/Dept. of Animal Nutrition and Management

   Author : Siri Sabina Johansson; [2020]
   Keywords : ensilering; foder; grovfoder; häst; näringsinnehåll; nötkreatur; phragmites australis; skörd; vass;

   Abstract : Vass (Phragmites australis) har historiskt sett använts som foder till framförallt nötkreatur, men på senare år har den blivit föremål för diskussioner som ett alternativt fodermedel till både nötkreatur och häst. I och med bristen på grovfoder år 2018 lyftes vass fram som en möjlig ersättare till odlat grovfoder. READ MORE

6. 5. Field study of the drought’s impact on feeding strategy and biological parameters in early lactation dairy cattle

   University essay from SLU/Dept. of Animal Nutrition and Management

   Author : Mikaela Würtz; [2019]
   Keywords : dairy cattle; drought; energy balance; feeding; metabolism;

   Abstract : The summer of 2018 was unusually warm and dry. For animal production, this resulted in poor pastures, reduced harvests of crops, such as roughage and grains, and increased risk for heat stress in the animals. The drought led to problems as in shortage of animal feed, which made the feeding of dairy cattle difficult. READ MORE
