Loss Function in Acturial Science and Estimation
(20190623)The nonlife insurance pricing consists of establishing a premium or a tariff paid by the insured to the insurance company in exchange for the risk transfer. A key factor in doing that is properly estimating the distribution ...

Integration in Lattice Spaces
(20190622)The goal of this thesis is to extend the notion of integration with respect to a measure to Lattice spaces. To do so the paper is first summarizing the notion of integration with respect to a measure on R. Then, a construction ...

Foundation of Stochastic Modeling and Applications
(20190622)This thesis presents an overview on the theory of stopping times, martingales and Brownian motion which are the foundations of stochastic modeling. We started with a detailed study of discrete stopping times and their ...

Employing Probabilistic Matching Algorithms for Identity Management in the Telecommunication Industry
(20190623)The telecommunication industry has a lot of data related to households, individuals and devices. Advertisers pay a premium to ensure they advertise to their target audience. To ensure that content is personalized, it is ...

Variational Inequality in Hilbert Spaces and their Applications
(20190623)The study of variational inequalities frequently deals with a mapping F from a vector 0 space X or a convex subset of X into its dual X . Let H be a real Hilbert space and a(u, v) be a real bilinear form on H. Assume that ...

LaSalle Invariance Principle for Ordinary Differential Equations and Applications
