To deal with severe drought when water supply is insufficient hedging rule, based on hedging rule curve, is proposed. In general, in discrete hedging rules, the rationing factors have changed from a zone to another zone at once. Accordingly, this paper is an attempt to improve the conventional hedging rule to control the changes of rationing factors. In this regard, the simulation model has emp...

There are many methods introduced to solve the credit scoring problem such as support vector machines, neural networks and rule based classifiers. Rule bases are more favourite in credit decision making because of their ability to explicitly distinguish between good and bad applicants.In this paper multi-objective particle swarm is applied to optimize fuzzy apriori rule base in credit scoring. ...

Background: General practitioners are the first who visit burn patients and they first calculate burn size and required fluid for the patient. Error in calculation can be disastrous. The purpose of this study is to compare four methods of estimating burn size to teach students. Methods: This is a descriptive-analytic study on 37 medical students. Four methods of estimating burn percentage was t...
