Understanding the climatic characteristics of a region plays a key role in sustainable development. The Esfahan province is extensive this factor has caused it variety climates. The regionalization climate of Esfahan has conducts with new methods of regionalization such as factor analysis and cluster analysis. The 25 variables have been selected from 12 stations for this purpose. The investigat...

Objective: The purpose of this study is to examine the effect of Auditors’ Individual Differences on their Professional Commitment. Also, the mediation effect of Ethical Climate Fit has been examined. Methods: According to the Social Cognitive Theory, two criteria of Internal Locus of Control and Self-Efficacy were used as Auditors’ Individual Differences. To measure the Internal Locus of Cont...

The main tasks for climate controllers in potato bulk stores are to keep the storage climate in an appropriate condition for quality conservation. To avoid extra energy costs by using cooling systems the internal climate of potato bulk stores is controlled with outdoor air. A conventionally designed controller is difficult to adapt for an optimal climate control to reduce quality loss. However,...

Meeting the climate challenge will require both mitigation and adaptation. New, improved, or adapted technologies will play an important, often central role, in both of these activities. The scale of the problem is obviously enormous; at the same time, its complexity is underlined by the wide range of technologies that will be required for mitigation and adaptation and the vast differences amon...

When current decisions affect welfare in the far-distant future, as with climate change, the use of a declining pure rate of time preference (PRTP) provides potentially important modeling flexibility. The difficulty of analyzing models with non-constant PRTP limits their application. We describe and provide software (available online) to implement an algorithm to numerically obtain a Markov Per...

Since 1996 a dynamic model based climate control concept (IntelliGrow) has been developed in Denmark. The aim of the system is to adjust the greenhouse climate dynamic, so that the natural resources are used as optimal as possible. The concept has been proved to work in both growth chamber and greenhouse experiments, with many different species of pot plants, resulting in energy savings up to 4...

This paper presents a model reference adaptive PD control scheme based on RBF neural network for the greenhouse climate control problem. A model of nonlinear conservation laws of enthalpy and matter between numerous system variables affecting the greenhouse climate is used to validate the proposed control scheme. Compared with the conventional adaptive PD control scheme based on RBF neural netw...
