[EN] The Smith chart was introduced by Philip Hagar Smith in 1939 and then refined and extended several years before becoming an icon of microwave engineering. To have a finite and practical size, the classical 2D Smith ...
[EN] We provide a sufficient condition for an operator T on a non-metrizable and sequentially
separable topological vector space X to be sequentially hypercyclic. This condition is
applied to some particular examples, ...

[EN] In this work, we apply the local Wendland radial basis function (RBF) for solving the time-dependent multi dimensional option pricing nonlinear PDEs.
Firstly, cross derivative terms of the PDE are removed with a ...

[EN] In this paper, we consider a random network model for sexual contacts in a population developed from real statistical data in order to assess vaccination policies against sexually transmitted diseases (STDs). The model ...
[EN] In this paper, a mathematical model to describe the spread of an infectious disease on a farm is developed. To analyze the evolution of the infection, the direct transmission from infected individuals and the indirect ...

[EN] Adapting curricula to the European space for higher education has been an opportunity for Spanish universities to perform a new approach to the structure of
their degrees. In this process takes a special importance ...
In this paper a method for computing hyperbolic matrix sine based
on Hermite matrix polynomial expansions is presented. An error bound analysis is
given
