1. The relative effect of gained extra-pair paternity versus ensured within-pair paternity on male fitness in collared flycatchers, Ficedula albicollis
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Variation in a male ability to gain extra-pair paternity and maintain within-pair paternity are important sources of variation in male fitness in socially monogamous species and thus become the resource of sexual selection on male secondary sexual traits. While the maximum possible number of offspring sired within the social pair-bond is limited by the female’s clutch size, the possible number of sired extra-pair young could in theory by much higher.

2. Evaluated density estimates of young forest stands using high resolution 2D imagery from UAV
University essay from SLU/Dept. of Forest Resource ManagementAbstract : After more than three decades of advanced technology and methods to evaluate young forest attributes, the forestry still prefers laborious field surveys in regenera-tion forests. Preceding studies have virtually all successfully identified the saplings, but the cost has outweighed the benefits or at least not yet convinced the companies to step away from the traditional field surveys; high-resolution photogrammetric point clouds and ALS-data can provide accurate estimations of the biophysical prop-erties but requires intense data processing.

3. Shelang : An Implementation of Probabilistic Programming Language and its Applications
University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystemAbstract : Nowadays, probabilistic models are playing a significant role in various areas in- cluding machine learning, artificial intelligence and cognitive science, etc. How- ever, as those models are becoming more and more complex, it shows that the corresponding programs are really hard to maintain and reuse as well.

4. Beam Loading Studies for Cavity Phase and Amplitude Setting
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : The purpose of this thesis is to study beam-cavity interactions, with a focus on how to maintain an unperturbed acceleration field in a conducting cavity with a proton beam present. The impact on a cavity acceleration field from different perturbation sources is investigated through computer simulations of a theoreti- cal model based on a resonant circuit. READ MORE
