  • Ruin theory under uncertain investments

    Creator:
    Constantinescu, Corina D.
    Abstract:
    An insurance company, having an initial capital u, receives premiums continuously and pays claims of random sizes at random times. A classical result states that if the rate of premium, c, exceeds the average of the claims paid per unit time, ⋋μ, then the ruin probability decays exponentially fast as...

  • Renewal risk processes with stochastic returns on investments : a unified approach and analysis of the ruin probabilities

    Creator:
    Constantinescu, Corina D.
    Abstract:
    This thesis considers one of the classical problems in the actuarial mathematics literature, the decay of the probability of ruin in the collective risk model. The claim number process N(t) is assumed to be a renewal process, the resulting model being referred as the Sparre Andersen risk model. The inter-claim...

  • High-temperature, high-pressure NMR probe for superconducting magnets

    Creator:
    Mullen, Corina P.
    Abstract:
    A high-temperature, high-pressure autoclave has been adapted for use with a high-field nuclear magnetic resonance spectrometer. The autoclave has an internal pressure range of atmospheric pressure to 1.5 kbar and a temperature range of 273 K to 1900 K. The autoclave is usable in a high field (8 T) magnet...

  • Asymptotic Results for Renewal Risk Models with Risky Investments

    Creator:
    Albrecher, H., Constantinescu, C., and Thomann, E.
    Abstract:
    We consider a renewal jump diffusion process, more specifically a renewal insurance risk model with investments in a stock whose price is modeled by a geometric Brownian motion. Using Laplace transforms and regular variation theory, we introduce a transparent and unifying analytic method for investigating the asymptotic behavior of ruin...

  • Methods for cost-sensitive learning

    Creator:
    Margineantu, Dragos D.
    Abstract:
    Many approaches for achieving intelligent behavior of automated (computer) systems involve components that learn from past experience. This dissertation studies computational methods for learning from examples, for classification and for decision making, when the decisions have different non-zero costs associated with them. Many practical applications of learning algorithms, including transaction...

  • Determining the relationship between measured residence time distributions in lateral surface transient storage zones in streams and corresponding physical characteristics

    Creator:
    Coleman, Anthony M.
    Abstract:
    Surface transient storage (STS) in stream ecosystems serve an important function in retaining nutrients and refugia for aquatic communities. Unfortunately, they can retain contaminants as well. Therefore, it is of importance to determine the residence time distribution (RTD). A RTD of a particular STS zone encompasses the time it takes...

  • Fusion enhancement with neutron-rich radioactive beams

    Creator:
    Zyromski, Kristiana Elizabeth
    Abstract:
    Fusion reactions with radioactive neutron-rich projectiles have been the subject of much recent theoretical and experimental interest. Predictions of enhancement of the cross section due to the use of a neutron-rich projectile may have implications for synthesis of heavy nuclei. In this work, the fusion-fission excitation functions were measured for...

  • Chemical cues and the molecular basis of olfactory chemoreception in caudate amphibians

    Creator:
    Kiemnec, Karen M.
    Abstract:
    Chemoreception is one of the dominant sensory modalities for many species of salamanders (reviewed in Chapter 2). At least seven of the ten currently recognized salamander families are known to respond to some sort of chemical cue. These responses are as varied as delaying hatching, seeking refuge, or initiating aggressive...

  • Eaffective Ecopoetics as a Practice for Feeling a World in Crisis

    Creator:
    Platt, Benjamin D.
    Abstract:
    Discussions of ecopoetics often seek to investigate how poetics as a form can be rendered more ecological, often in contrast to nature poetry. These conversations tend to concentrate on this generic contrast and the formal qualities of an ecological poetics. Ecopoetics as a field emerged largely as a response to...
