The experimental technique of fluorescence light observation is used in current and planned air shower experiments that aim at understanding the origin of ultrahigh energy cosmic rays. In the fluorescence technique, the geometry of the shower is reconstructed from the correlation between arrival time and incident angle of the signals detected by the telescope. The calculation of the expected li...

Co-management, or the joint management of the commons, is often formulated in terms of some arrangement of power sharing between the State and a community of resource users. In reality, there often are multiple local interests and multiple government agencies at play, and co-management can hardly be understood as the interaction of a unitary State and a homogeneous community. An approach focusi...

Recent scientific innovations, and proposed legislation, have raised questions about the nature of the constitutional right to reproductive freedom, and in particular about whether there is a constitutional “right to clone.” This essay urges that as a matter of substantive due process, rationality review is probably appropriate, and that restrictions on both reproductive and therapeutic cloning...

The goal of this research is to investigate the factors that affect carsharing demand. As a proxy for carsharing demand, the number of (booking) transactions made by carsharing users is counted based on the data from one of the two major carsharing operators in Seoul, Korea. In order to identify the factors influencing station-based carsharing usage, multiple linear regression modeling was perf...

Background Although chronic obstructive pulmonary disease is a known cause of secondary polycythemia with elevated erythropoietic demands in response to hypoxemia, anemia is relatively common in patients with chronic obstructive pulmonary disease and is related to increased mortality. However, little is currently known about the relationship between various iron parameters and disease severity ...

We consider leptogenesis induced by soft supersymmetry breaking terms (“soft leptogenesis”), in the context of the inverse seesaw mechanism. In this model there are lepton number (L) conserving and L-violating soft supersymmetry-breaking B-terms involving the singlet sneutrinos which, together with the – generically small– L-violating parameter responsible of the neutrino mass, give a small mas...

Gaussian processes reinforcement learning provides an appealing framework for training the dialogue policy as it takes into account correlations of the objective function given different dialogue belief states, which can significantly speed up the learning. These correlations are modelled by the kernel function which may depend on hyper-parameters. So far, for real-world dialogue systems the hy...

This paper discusses and analyzes risk measure properties in order to understand how a risk measure has to be used to optimize the investor’s portfolio choices. In particular, we distinguish between two admissible classes of risk measures proposed in the portfolio literature: safety risk measures and dispersion measures. We study and describe how the risk could depend on other distributional pa...

Short Summary (in English) 66 Short Summary (in Hungarian) 67 ii Acknowledgements First of all, I would like to express my thanks to my supervisor András L®rincz for the continuous support and trust. I'm deeply indebted to the members of his research group for the friendly atmosphere and for their readiness to help. Namely, to Zoltán Bárdosi, István Szita and Bálint Takács. I'm especially grate...

We tend to sympathize with addicts who behave illegally or immorally in service of their addictive cravings more readily than we do with those who act in exactly the same ways but who are not addicted. The addict who kills for money to buy crack seems less a moral monster than the unaddicted person who coldly plots the same murder for the same purpose. This distinction in our moral sentiments s...
