Temperature is one of the main climatic elements that can indicate climate change as climate change seems to be one of the most important issues in the recent two decades. The aim of this research is to study temporal variation in temperature over Dibrugarh city, Assam, India during the period 1981–2010. In this article we are interested in the time series modeling of the average monthly mean t...

In this paper, we obtain the explicit limit value of the Teichmüller distance between two Teichmüller geodesic rays which are determined by Jenkins-Strebel differentials having a common end point in the augmented Teichmüller space. Furthermore, we also obtain a condition under which these two rays are asymptotic. This is similar to a result of Farb and Masur.

Dryer system is a controlled plant which is normally used in chemical industry. The proper modeling of this system facilitates its maintenance and keeping. Normally this is not an easy task, unless having a complete model of the process, due to sudden and nonlinear events. In this paper the linear identification of dryer plant in Arak petroleum, is introduced according to the Autoregressive wit...

This study compares the forecasting performance of various Autoregressive integrated moving average (ARIMA) models by using time series data. Primarily, The Box-Jenkins approach is considered here for forecasting. For empirical analysis, we used CPI as a proxy for inflation and employed quarterly data from 1970 to 2006 for Pakistan. The study classified two important models for forecasting out ...

General aspects of modeling as an engineering tool are presented in this work. The usefulness of Takagi-Sugeno Fuzzy Inference Systems (TS FIS) as modeling technique are emphasized. Additionally, various modifications of known methodology for identifying such a models and rules configuration are proposed. Finally, two application examples are presented. The first one is a modeling of the Box an...

Kenya’s horticulture sector is one of the key contributors to country’s national income. In this paper, we apply Box-Jenkins SARIMA time series modeling approach develop a model that best describes income economy from export produce. process analysis, considered monthly data August 1998 March 2023. It was found that, SARIMA(3; 1; 4)(0; 0)12 suitable

Time-series analysis, a relatively uncommon technique in ecological studies, has been applied to annual tree growth-ring series. In agreement with earlier North American work, ARMA(1,1) models were found to be the predominant form for expressing stochastic growth processes, occurring in 58% of the 36 Nothofagus menziesii and N. solandri time-series examined. The remaining 42% conformed to an AR...
