The theory has been focused, in particular, on systems possessing internal lags, those being described by functional differential equations, those being characterized as hybrid dynamic systems and those being described by coupled continuous-time and discrete-time dynamics, [6 10].
For that, software components must be described by their functional and non-functional properties.
The structural nature of the organic corrosion inhibitor and inhibition mechanism can be described by density functional theory (DFT).
Furthermore, our results suggest that return distributions for stocks from different exchanges, time periods, and over different time scales can be described by one functional form.
Some of these categories can overlap to some extent with functional annotations (for example, several genes encoding proteins from the same pathway or protein complex may be described by the same functional annotation comprising a common Gene Ontology term).
A dimensional analysis method was adopted to normalize the pressure drop trend considering that the dynamic properties and the flow behaviour can be different for any CAF line, and the concept can be described by the following functional relation: fleft( {Delta Pleft( t right),left( {Delta P_{i} } right),left( {Delta P_{w} } right),mu_{o},mu_{w},h_{o},U_{sw},L,t,t^,Delta t,V_{D},V} right) = 0 (2).
The majority of proteins (>50%) could be described by a single functional term in ~75% of E. coli and yeast complexes.
Three-dimensional images can be described by four Minkowski functionals that relate to volume, surface area, integral mean curvature (IMC) and integral total curvature (ITC) (see Materials and Methods for further details).
Two-dimensional (2D) images can be described by three Minkowski functionals: area fraction, boundary length and the Euler number (Mattfeldt et al., 2007), and these have been used to characterise tissue samples and have been linked to pathology classification using 2D images of breast tissue.
The aim of this paper is to demonstrate on the basis of the author's own mathematical models of across-wind load on a slender structure of circular cross-section at vortex excitation, that the correlation function and, subsequently, the power spectral density of this load can be described by universal formulas of two functional parameters which should be determined experimentally.
