Model discrimination for reactions with stop-effect

Abstract

Several basic models presented in the literature for reactions with a stop-effect yield virtually the same results under steady state conditions. Such a situation takes place for dehydration of alcohols and the deamination of primary amines. It has been proved that a simple transient behaviour after a stop in the supply of the reactant will not make it possible to distinguish between the models. However, a considerable difference in the mean reaction mte under forced concentration oscillations between the models can be observed. The difference decreases with an increase in the cycling time.

Stop sign

A stop sign is a traffic sign designed to notify drivers that they must come to a complete stop and make sure the intersection is safely clear of vehicles and pedestrians before continuing past the sign. In many countries, the sign is a red octagon with the word STOP, in either English or the national language of that particular country, displayed in white or yellow. The Vienna Convention on Road Signs and Signals also allows an alternative version: a red circle with a red inverted triangle with either a white or yellow background, and a black or dark blue STOP.

Steady state

In systems theory, a system or a process is in a steady state if the variables (called state variables) which define the behavior of the system or the process are unchanging in time. In continuous time, this means that for those properties p of the system, the partial derivative with respect to time is zero and remains so: In discrete time, it means that the first difference of each property is zero and remains so: The concept of a steady state has relevance in many fields, in particular thermodynamics, economics, and engineering.

Model selection

Model selection is the task of selecting a model from among various candidates on the basis of performance criterion to choose the best one. In the context of learning, this may be the selection of a statistical model from a set of candidate models, given data. In the simplest cases, a pre-existing set of data is considered. However, the task can also involve the design of experiments such that the data collected is well-suited to the problem of model selection.
