In this study we use cointegration methods to investigate the relationship between the variables of the Ohlson model (stock price, earnings per share and book value) with panel data. The cointegration tests were applied at individual and group level (by…

We describe a technique for using Bode plots in microscopic interferometry, in particular as applied to the three Gaussian beam interferometer recently reported in the literature. The technique is used in a similar manner to its application to an electric…

El trabajo presenta la metodología empleada en el proceso de vigilancia tecnológica y documental que se está llevando a cabo en el seno del proyecto INREDIS. Se argumenta que la vigilancia tecnológica es una tarea cada vez más utilizada por…

En este trabajo se presentan los tres tipos de comportamiento temporal de estrellas de bosones esféricamente simétricas, es decir: configuraciones estables, inestables que colapsan para formar agujeros negros e inestables que explotan. Estas tres posibilidades han sido predichas por la…

In this paper a methodology is presented which allows a quick and simple means of estimating the potential energy that can be obtained from a tidal power plant. The evaluation is made using a normalised nomograph, which is a function…

The unit cell of a graphite crystal is analyzed by using the basic principle of the harmonic oscillator. For this purpose, we consider the atoms that conform the hexagonal unit cell, connected by small springs. The equation of motion of…

The proper orthogonal decomposition (POD) is shown to be an efficient model reduction technique for simulating physical processes governed by partial differential equations. In this paper, a POD reduced model of a barotropic ocean circulation for coastal region domains was…

Se investigó el efecto de la absorción móltiple de fotones en la ionización, MPI, y disociación, MPD, del Naftaleno. Para ello se utilizó radiación láser de 266 nm con anchos de pulso de 4.5 ns, e intensidades del orden de…

The differentiation is the most important concept in Bowen's theory. This implies the degree of emotional independence that a subject has with important people within his environment. This concept hasn't been studied much in spite of its important implications toward…

In some industries such as logistics services, bank services, and others, the use of automated systems that deliver critical business information anytime and anywhere play an important role in the decision making process. This paper introduces a “Generic model to…
