11. Bluetooth Based Bird Detection System
Kandidat-uppsats, Blekinge Tekniska HögskolaSammanfattning : Context: Windmills became one of main sources of energy. Sincethey are placed in open areas, there are many chances that birds mayenter the wind farms and get killed or damaged. Some wind farms usepulse radar systems for saving the birds from windmills. In this pulseradar technology, the turbines are turned off automatically when a birdis detected. LÄS MER
12. Estimating Future Forest Fire Risk in Gävleborg County Sweden in 2041-2070 Following RCP 8.5
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Forest fires can act as an ecosystem service by providing habitat renewal, controlling pests, and reducing the risk of extreme fires, but can at the same time disturb an ecosystem negatively. Furthermore, forest fires release carbon dioxide into the atmosphere, damage property, and lead to health issues. LÄS MER
13. Estimation of respiratory frequency from Heart Rate Variability
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : In this master's thesis the ability to estimate the respiratory frequency from heart rate variability measurement is analyzed. The goal was to implement a solution that is easily transferable to real time. LÄS MER
14. En grönare järnväg
Uppsats för yrkesexamina på grundnivå, Lunds universitet/Trafik och vägSammanfattning : Detta arbete är en utredning av hur järnvägskonstruktionens emissioner ser ut vid anläggning. Den samlade datan har översatts i ett matematiskt uttryck som ger ett minsta årtal för när en neutraliseringshorisont för projektet kan nås. LÄS MER
15. Sound Source Distance Estimation Using Sound Frequency Attenuation
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Estimating the distance between a sound source and receiver is an important problem. This thesis explores the possibility of estimating distance from a sound source using the attenuations regarding different frequencies over a distance. This method can be useful in cases where currently existing distance approxima- tion methods are not an option. LÄS MER
