this paper tries to systematically survey, with taking theoretical view on geomorphic basin and its changes into account. the purpose of this research is to determine the balance and stability of geomorphic basins from the past to present and then to future. consequently, it tries to determine the balance between energy and input-output materials for example (rainfall , solar radiation, tectoni...

this paper employs a multivariate dynamic conditional correlation garch model, which is developed by engle (2001, 2002), to detect the timing and nature of changes in the comovement between iranian output and prices for the periods after iran–iraq war , known as imposed war . the results showed that there is a weak correlation between output and prices after imposed war and  varies periodically...

This paper deals with several related notions of output stability with respect to inputs (which may be thought of as disturbances). The main such notion is called input to output stability (ios), and it reduces to input to state stability (iss) when the output equals the complete state. For systems with no inputs, ios provides a generalization of the classical concept of partial stability. Seve...

The output of an association rule miner is often huge in practice. This is why several concise lossless representations have been proposed, such as the “essential” or “representative” rules. We revisit the algorithm given by Kryszkiewicz (Int. Symp. Intelligent Data Analysis 2001, Springer-Verlag LNCS 2189, 350–359) for mining representative rules. We show that its output is sometimes incomplet...

We consider the problem of determining when two dataaow networks with uninterpreted nodes always have the same input-output behavior. We deene a set of behavior-preserving transformations on networks and show that this set is \schematologically complete", i.e., networks have the same input-output behavior under all interpretations if and only if they can be transformed into isomorphic networks....

The paper examines the development of models of steam generation plant using linear identification techniques. The identification process is carried out using experimental data of a multi-input multi-output MIMO system representation. Various techniques of modeling and identification are applied considering the complete system as a MIMO model and studying the effect of all the inputs on individ...

We discuss the possibility of generating noncritical quadrature squeezing by spontaneous polarization symmetry breaking. We first consider Type II frequency-degenerate optical parametric oscillators but discard them for a number of reasons. Then we propose a four-wave-mixing cavity, in which the polarization of the output mode is always linear but has an arbitrary orientation. We show that in s...

It is possible, by appropriate programming language extensions, to use the assignment statement as the sole means of changing the value of a variable, thereby eliminating the need to modify routine arguments by output parameters. Several suggestions are made to enhance the syntax and semantics of routine definition and assignment to maintain notational convenienceand efficient execution normall...

A notion of detectability for nonlinear systems is discussed. Within the framework of “input to state stability” (ISS), a dual notion of “output to state stability” (OSS), and a more complete detectability notion, “input-output to state stability” (IOSS) have appeared in the literature. This note addresses a variant of the IOSS property, using an integral norm to measure signals, as opposed to ...
