Este artículo investiga la relación entre tasas de interés e inflación para la economía chilena (1975/1979). Se contrasta una versión modificada de la hipótesis de Fisher. Sorprendentemente los resultados tienden a evidenciar el hecho de que en Chile, el ajuste ante cambios en la tasa de...

We study the dynamics of moving discrete breathers in an interfaced piecewise DNA molecule. This is a DNA chain in which all the base pairs are identical and there exists an interface such that the base pairs dipole moments at each side are oriented in opposite directions. The Hamiltonian of the...

This paper is concerned with the estimation of the volatility process in a stochastic volatility model of the following form: $dX_t=a_tdt+\sigma_tdW_t$, where $X$ denotes the log-price and $\sigma$ is a c\`adl\`ag semi-martingale. In the spirit of a series of recent works on the estimation of...

A dynamical model to describe the behavior of a traffic line is proposed. The model incorporates the wishes of the drivers, following the ideas of Prigogine and collaborators. Interactions among cars are described in a stochastic way, by means of a probability of passing. Results of computer...

A method for finding the state distribution in a physical system, on the basis of a detailed analysis of the experimental response of the system to an external probe, is presented. The concomitant algorithm, based upon the maximum entropy principle, is specifically devised so as to take into...

In the present paper we present an experimental analysis and a thermal and hydrodynamic modelling of a newly designed flat-plate solar collector characterized by its corrugated channel and by the high surface area directly in contact with the heat transport fluid. The thermal and hydrodynamic...

Agricultural production estimates have often differentiated and estimated different technologies within a sample of farms. The common approach is to use observable farm characteristics to split the sample into groups and subsequently estimate different functions for each group. Alternatively,...
