Sharks are highly vulnerable to intense and prolonged fishery extraction. This article analyzes the data on shark landings from the artisan fishing fleet on Costa Rica's Pacific coast between 1988 and 1997. The data come from an invoicing system administered by the Costa Rican Fisheries Institute (Instituto Costarricense de la Pesca y Acuacultura, INCOPESCA). Pacific coast shark fishing during ...

considering importance and the role of forecasting water consumption in water resources management and implementing appropriate short- and long-run policies in order to optimize water demand, therefore, this study aims to provide a model for predicting the water consumption via box and jenkins method. to this end, monthly data for the domestic and agricultural water consumptions of tehran provi...

rain modeling in recent years has been of great importance in water resource management and its function in long term and short term planning, especially its great effect on agricultural economy. to reach to good results box-jenkins model is much more efficient. the writers of this article have used the data collected in tabriz and oroumiyeh stations in a fifty year period and then presented th...

This paper deals with design of a model for short-term heat demand forecasting. Forecast of this heat demand course is significant for short-term planning of heat production and it is most important for technical and economic consideration. In this paper we propose the forecast model of heat demand based on the assumption that the course of heat demand can be described sufficiently well as a fu...
