Abstract: Proposed method, called Probabilistic Nodes Combination (PNC), is the method of 2D curve modeling and handwriting identification by using the set of key points. Nodes are treated as characteristic points of signature or handwriting for modeling and writer recognition. Identification of handwritten letters or symbols need modeling and the model of each individual symbol or character is built by a choice of probability distribution function and nodes combination. PNC modeling via nodes combination and parameter γ as probability distribution function enables curve parameterization and interpolation for each specific letter or symbol. Two-dimensional curve is modeled and interpolated via nodes combination and different functions as continuous probability distribution functions: polynomial, sine, cosine, tangent, cotangent, logarithm, exponent, arc sin, arc cos, arc tan, arc cot or power function.

Abstract: This paper does an inventory of the navigation systems under development which promise to be key systems in the following decades. But the main aim of the article is to add some complementary tools of the spot light to the navigation systems to assure they arrive at the port, based on information technologies and social structures. Weather Information, conditions of the infrastructure and social movements may be sources of efforts to improve a mature technology. The Global Positioning System shows you the way to get there, but the virtual sailing master shows you how to get there.
