The objective of this study is to propose a new method for text region localization and character extraction in natural scene images with complex background. In this paper, a hybrid methodology is suggested which extracts multilingual text from natural scene image with cluttered backgrounds. The proposed approach involves four steps. First, potential text regions in an image are extracted based...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
We consider nonparametric regression models in which the regression function is a step function, and construct a convolution estimator for the response density that has the same bias as the usual estimators based on the responses, but a smaller asymptotic variance.
Nowadays, there are too many models in the world for simulation of hydrological processes, such as the SWAT physically based model. The SWAT model is a continuous and physically based hydrologic model that is the smallest unit in this model is Hydrologic Response Unit, and all hydrological processes are simulated in each of these units. This model can simulate runoff, sedimentation, erosion and...
Communicative moves and lexical cohesion patterns (LCPs), as mounting evidence shows, are two important indicators in writing and publishing the RAs. However, the interaction between these two crucial elements and the contribution of this interaction to the failure or success of the RAs have not been given due attention to date. Having this in mind and based on a sound theoretical framework, at...
چکیده گرچه معمولا بخش قدردانی در قیاس با بخشهای مهم نوشتارعلمی در حاشیه قرار می گیرد، اما به عنوان یک ژانر در گفتمان دانشگاهی به طور گسترده ای به منظور ابراز تشکر نسبت به فرد یا نهادی در قبال کمک آنها و نیز برای نیل به جایگاه علمی و اجتماعی دلخواه به کار گرفته می شود. از این رو، با توجه به اهمیت بخش قدردانی در نوشتار علمی و با توجه به اینکه مطالعات اندکی به بررسی این بخش در محیط دانشگاهی ایرا...
Abstract—the purpose of this paper is to compare two artificial intelligence algorithms for forecasting supply chain demand. In first step data are prepared for entering into forecasting models. In next step, the modeling step, an artificial neural network and support vector machine is presented. The structure of artificial neural network is selected based on previous researchers' results. For ...

Abstract This study applies panel data techniques to investigate the long-run relationship between energy consumption and GDP for a panel of 19 African countries (COMESA) based on annual data for the period 1980-2005. In the first step, we examine the degree...
