  • 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...

  • 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...

  • 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...

  • Atmospheric boundary layer coupling to midlatitude mesoscale sea surface temperature anomalies

    Creator:
    Thum, Nicolai
    Abstract:
    This thesis examines the mechanisms that couple the monthly-averaged atmospheric boundary layer (ABL) to open-ocean sea surface temperature (SST) perturbations on scales of 50-500 km. The observed positive correlation between surface wind speed anomalies and SST anomalies is successfully simulated using the Weather Research and Forecasting (WRF) model. In numerical...

  • Error control techniques for the Z-channel

    Creator:
    Oprisan, Paul
    Abstract:
    The asymmetric nature of bit errors in several practical applications provides grounds for efficient error control techniques. The Z-channel model and special classes of codes like asymmetric error detection codes and t-asymmetric error correcting/d-asymmetric error detecting codes can be successfully used in ARQ protocols for feedback error control enhancement. This...

  • A molecular and morphologic study of idiopathic fetlock hyperextension and suspensory apparatus breakdown in the llama

    Creator:
    Reed, Shannon Kelly
    Abstract:
    Suspensory apparatus breakdown and hyperextension of the metacarpophalangeal and metatarsophalangeal (fetlock) joints is a common condition in the llama and has been observed in llamas of all ages. Llama breeders refer to the condition as "down in the pasterns" or "down in the fetlocks." The condition can result in debilitating...

  • Learning cost-sensitive diagnostic policies from data

    Creator:
    Zubek, Valentina Bayer
    Abstract:
    In its simplest form, the process of diagnosis is a decision-making process in which the diagnostician performs a sequence of tests culminating in a diagnostic decision. For example, a physician might perform a series of simple measurements (body tem- perature, weight, etc.) and laboratory measurements (white blood count, CT scan,...

  • Dental Amalgam Fillings: The Scientific Evidence for Safety

    Creator:
    Young, Matthew J.
    Abstract:
    Objective: To explore the controversial issue of the safety and use of mercury in amalgam dental fillings. Methods: Using a variety of scientifically oriented studies, overall trends and conclusions were analyzed. Relevant articles include Children’s exposure to Amalgam, fetal exposure, environmental mercury, occupational exposure, and mercury and Multiple Sclerosis. Additional...

    Creator:
    Shams Sobhani, Ehsan
    Abstract:
    Many engineering devices and propulsion systems suffer from undesirable effects of cavitation; such as degradation in the efficiency of pumps and turbines, generation of noise and vibration on ship propeller, increased drag and erosion of propeller blade, etc. In spite of decades of research on this problem, detailed study of...
