1. 16. Reinventing The Switch : How Might We Facilitate Adapting Lighting Conditions To Users’ Needs In Homes

   Magister-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

   Författare :Ghaith Alhalaby; [2022]
   Nyckelord :interaction with light; family home; machine learning; AI; ambient intelligence; user experience;

   Sammanfattning : Light shapes the environment we live in and thereby our lives. The advancement in technology made it possible to accurately adjust different light properties. This high level of control is promising and changing at the same time. Taming this complexity and providing users with meaningful ways to interact with light is at the core of this mission. LÄS MER

3. 17. Electrical Impedance Profiling of Plants, Coffee and TREO

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och system

   Författare :Adam Bushara; Sebastian Daniel Clyne; [2022]
   Nyckelord :;

   Sammanfattning :  The aim of the project was to investigate the possibility of using low-cost hardware to monitor plant health, measure the impedance of water containing dissolved substances at different concentrations, and observe how the plant impedance is affected compared to auxiliary measurements of soil moisture, ambient light, humidity, and temperature.To measure impedance, we used electrical impedance spectroscopy which gives the impedanceacross a spectrum of frequencies.

4. 18. 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

5. 19. Predicting Top-Oil-Temperature in Power Transformers with Light Gradient Boosting Machine

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Victor Löfgren; [2022]
   Nyckelord :;

   Sammanfattning : Online monitoring of mineral-oil-immersed transformer variables provide capabilities such as failure avoidance, optimization of load capacity and maintenance as well as extending the remaining life expectancy. A central role is played by the Top-Oil-Temperature which in its own is an indicator of harmful events or transformer states. LÄS MER

   Nyckelord :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;

   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
