Typical measures for closed loop systems are so-called gaps between two systems, classically either L2 or H2 gap. Here, the distance between to candidate models for a plant can be measured taking all possible combinations of bounded input and output signals into account. Rather recently, a variant of theses gaps, the ν − gap, gained interest in the “identification for control” community. This r...

The Correspondence model of base-reduplicant identity (McCarthy & Prince 1995, to appear) makes the prediction that any kind of segmental phonological process may result in any of these situations through ranking of phonological constraints with faithfulness constraints on the input and output and the basereduplicant relationship. Normal application arises when base-reduplicant faithfulness con...

In this paper, aiming at the problems of backward overall technology, weak competitiveness, poor operation efficiency and low production and economic efficiency in Liaoning equipment manufacturing industry, we based on the theory of constrains and used the DEA model to research its technology upgrading input and output efficiency to find its bottleneck, and then analysis its cause, finally put ...

This paper presents a safeness condition that is more liberal than the one commonly imposed on Datalog, based on classifying predicate arguments into input and output arguments, thereby extending the expressiveness of Datalog-based policy languages. It is also shown that the relaxed safeness condition is a powerful tool for adding important features to such languages.

The core idea of the lens model consists in ascribing the individual organism the critical ability to recognize a heterogeneous and intricate selection in the ecology on both the input and output side, by establishing new foci, or simply by ignoring some aspects. In the center of attention within this model is the selection of vital distal issues on the basis of cues, as handled by the “central...

This paper considers identification problems of multirate multi-input sampled-data systems. Using the continuous-time system discretization technique with zero-order holds, the mapping relationship (state–space model) between available multirate input and output data is set up. The multi-innovation identification theory is applied to estimate the parameters of the obtained multirate models and ...

Stability and L2 (l2)-gain of linear (continuous-time and discrete-time) systems with uncertain bounded time-varying delays are analyzed under the assumption that the nominal delay values are not equal to zero. The delay derivatives (in the continuous-time) are not assumed to be less than q < 1. An input–output approach is applied by introducing a new input–output model, which leads to effectiv...

We present a simple model for synthesis of butterfly wing patterns. The model simulates the formation of eyespots as are called the rounded circular arrangements which appear in many butterfly species. We illustrate our results with the examples of Diatheria clymena and Automeris io species.

To make the right decisions, farm managers should have insight into the potential impact of management decisions on technical performance and economic results. In the Netherlands the (non-productive) rearing period of dairy heifers covers, on average, 26 months. Such a significant time lag between input and output makes it difficult for a dairy farmer to recognize the impact of various decision...
