Bayesian Probabilistic Reasoning Applied to Mathematical Epidemiology for Predictive Spatiotemporal Analysis of Infectious Diseases

Description: Abstract Probabilistic reasoning under uncertainty suits well to analysis of disease dynamics. The stochastic nature of disease progression is modeled by applying the principles of Bayesian learning. Bayesian learning predicts the disease progression, including prevalence and incidence, for a geographic region and demographic composition. Public health resources, prioritized by the order of risk levels of the population, will efficiently minimize the disease spread and curtail the epidemic at … more

Operators on Continuous Function Spaces and Weak Precompactness

Description: If T:C(H,X)-->Y is a bounded linear operator then there exists a unique weakly regular finitely additive set function m:-->L(X,Y**) so that T(f) = ∫Hfdm. In this paper, bounded linear operators on C(H,X) are studied in terms the measure given by this representation theorem. The first chapter provides a brief history of representation theorems of these classes of operators. In the second chapter the represenation theorem used in the remainder of the paper is presented. If T is a weakly compact o… more

My Whine, Your Wine

Description: Grapes hold the flavors of the lands where they grow, and when you make wine from them, those flavors of the land come through. Tasting wine from a place you've been can bring you back to that place with aromas and notes indicative of that place. A bottle of wine changes every day, and how it will taste depends on the moment you choose to release it from the glass walls. I have a vested interest in wine, because it is a living thing. I am compelled to make wine because its characteristics are l… more
