A simple modelling procedure for the time series of wind speed is presented. Using the statistical properties of the joint distribution of wind speed and direction the modelling problem is reduced to one of modelling a stationary Gaussian process. This model can be used to generate the time...

This paper solves the input-output decoupling problem of three-dimensional (3-D) systems formulated in state-space representation. The control policy adopted is of the static state feedback type u=Kx+Nw where K, N are appropriate matrices to be determined, x is the system state vector, and w is...

This paper presents an overview of some simulation techniques employed by local government administrations in Japan. As urbanization causes serious impacts on the natural environment, administrations are faced with environmental protection as a social issue. For any administration in looking for...

The analysis of multiple indicator dilution curves to estimate the rates of transport of ions and substrates across the sarcolemma of myocardial cells requires the formulation of models for the blood-ISF-cell exchanges. The fitting of models to the sets of experimental data is dependent of...

We develop ultra-arithmetic, a calculus for functions which is performable on a digital computer. We proceed with an analogy between the real numbers and their truncated positional number representations on the one hand and functions and their truncated generalized-Fourier series on the other....

In Part 1 of this paper (Function Data Types) we developed ultra-arithmetic. a calculus for functions which is performable on a digital computer. Here in analogy with the notion of interval arithmetic for intervals of reals we begin the development of an interval arithmetic for functions. The...

One of the fundamental problems in stochastic modeling of dynamic systems is to what extent the study of stochastic analysis differs with corresponding deterministic analysis. This work focuses the attention of finding estimates on the variation of stochastic solutions and the corresponding...

The real-time surveilance of evolving hydrological systems is particularly attractive in situations where models are used in a control capacity. If the parameters of a process are time variant, it is meaningless to approach the identification problem in any way other than to track their...

Using moving averages to introduce autocorrelation into a sequence of pseudorandom variables will most often distort the shape of the distribution. When the correlation coefficients are to be zero from some lag onward, it is possible to compensate for most of the distortion by starting with...

A somewhat different view of sensory perception is presented. It is supposed that the perceptual process consists of two phases: the establishment of uncertainty about some feature of the environment, and the progressive removal of this uncertainty. The first phase demands active participation...
