Duration Distribution and Up-crossings Rate of Generalized Hyperbolic Processes
A Gaussian process is usually used to model the sea surface elevation in the oceanography. As the depth of the water decreases or the sea severity increases, the sea surface elevation departs from symmetry and Gaussianity. In this paper, a stationary non-

The HS-SAS and GSH-SAS Distribution as Model for Unconditional and Conditional Return Distributions
We introduce two new skewed and leptokurtic distributions derived from the hyperbolic secant distribution and from Vaughan (2002)’s generalized hyperbolic distribution by use of the sinh-arcsinh transformation introduced in Jones and Pewsey (2009 ...

Modeling Insurance Claim Distribution via Mixture Distribution and Copula [PDF]
This paper analyses whether joint probability distribution function of losses due to different exposures covered under the same policy could be modeled in an appropriate manner via mixture distribution proposed and copula concept.

Skew Generalized Secant Hyperbolic Distributions: Unconditional and Conditional Fit to Asset Returns
A generalization of the hyperbolic secant distribution which allows for both skewness and leptokurtosis was given by Morris (1982). Recently, Vaughan (2002) proposed another flexible generalization of the hyperbolic secant distribution which has a lot of

Convergence and Numerical Solution of a Model for Tumor Growth
In this paper, we show the application of the meshless numerical method called “Generalized Finite Diference Method” (GFDM) for solving a model for tumor growth with nutrient density, extracellular matrix and matrix degrading enzymes, [recently proposed ...

The Skew Generalized Secant Hyperbolic Family
We introduce a skewness parameter into Vaughan’s (2002) generalized secant hyperbolic (GSH) distribution by means of exponential tilting and develop some properties of the new distribution family.

In this paper, a novel mathematical—physical model of the generalized elasto-thermodiffusion (hole/electron interaction) waves in semiconductor materials is studied when the hyperbolic two-temperature theory in the two-dimensional (2D) deformation is ...
