16. Miniaturization of a Low Power Harmonic Radar for UAV use
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : The aim with this Master thesis work is to design, build and test a small size, light weight and low power consumption harmonic radar system that will be installed in a flying drone for the purpose of tracking and localizing tagged Bogong moths near their aestivation caves and crevices in Australia during summer. A FMCW harmonic radar is proposed, it comprises a radar transmitter, receiver and a signal processor. LÄS MER
17. Fjällbjörkmätarlarvers påverkan på fjällbjörkskog : en fjärranalysstudie om markvegetationsförhållanden i subalpin miljö

19. Moth and Birch
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : The goal of this thesis is to build a near-real time defoliation detector that could be used, early in the spring, to find out which areas of a birch forest are being affected by an insect outbreak. The importance of a reliable detection at the beginning of the spring lies on the possibility for an early intervention. LÄS MER
20. Which Analysts Make the Best Stock Recommendations?
C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomiSammanfattning : This paper uses a set of 4566 stock recommendations for companies traded on the Stockholm stock exchange during the five year period 2010-2014 to investigate what factors affect analysts' stock-picking ability. We begin our analysis by using a buy-and-hold strategy to establish the presence of stock recommendation announcement effects and long term over performance. LÄS MER
