Abstract Nonlinear phenomena are universal in ecology. However, their inference and prediction generally difficult because of autocorrelation outliers. A traditional least squares method for parameter estimation is capable improving short-term by estimating autocorrelation, whereas it has weakness to outliers consequently worse long-term prediction. In contrast, a robust regression approach, su...

It is extremely critical for an emergency response to quickly and accurately use source term estimation (STE) in the event of hazardous gas leakage. To determine appropriate algorithm, four swarm intelligence optimization (SIO) algorithms including Gray Wolf optimizer (GWO), particle (PSO), genetic algorithm (GA) ant colony (ACO) are selected be applied STE. After calculation, all can obtain le...

in recent years, various time series models have been proposed for financial markets forecasting. in each case, the accuracy of time series forecasting models are fundamental to make decision and hence the research for improving the effectiveness of forecasting models have been curried on. many researchers have compared different time series models together in order to determine more efficient ...

considering the importance of the agriculture sector in iran, this study investigated factors affecting economic growth and development of the agriculture sector in iran over the period of 1967-2009 for short term and long term, using ardl model. the results showed that the ratios of public investment expenditure to the gdp for short-term and long term have positive impacts on the economic grow...

in this study, combined effect of two essential oils, thymol and carvacrol, with different concentrations in two methods on gladiolous grandiflorous l. was investigated based on a completely randomized design with 3 replicates and four flower in each replicate. sansusi variety applied that was red. in short term method, different concentrations of thymol and carvacrolin including 25+25, 50+50 a...

we aimed to evaluate the potential of growing rats as a model of osteoporosis induced by short term hypercholesterolemia. twelve growing female sprague-dawley rats were randomly allocated into two groups. control rats received standard diet while rats in group 2 were fed with diet contained 20% sunflower oil, 2% cholesterol and 0.5% cholic acid for 2 weeks and then a diet contained 10% sunflowe...
