The main goal of this paper is to propose a new practical method for hydrologic soil group estimation in surface runoff process based on geomorphology facieses and slop. The determination of CN based on this method can reduce the time and cost of project. In this research the upstream rivers of Glinak Watershed have been used as a case study to examine the efficiency of proposed method with a c...

The Study of river water quality interation with lakes and dam reservoirs is important from anexploitation point of view. When river water with different densities enters a lake or dam reservoir,underflow density current phenomenon occurs. Because of the density, so understandingdifferent arrays of this phenomenon Seems necessary for checking erosion and sedimentationprocesses and their managem...

RFID-based location awareness is becoming the most important issue in many fields in recent years, such as ubiquitous computing, mobile computing. In indoor localization systems RSSI-based methods are usually used in office buildings. However, RSSI is susceptible to external influences, and performances unstably due to the environmental factors affecting signal propagation. In this paper, we pr...

Objectives: To improve the efficiency of tri-level segmentation tasks for handwritten Gujarati text. Methods: Using hybrid methods segmentation, we have used line, word and character from image. This study presents a paradigm that works with touching characters, slop line written on page, overlapping, etc. It evaluated dataset 500+ images created by us different writing sentences people. We Hor...

the main aim goal of this paper is estimating time series of social capital in iran. for this aim, first we have reviewed theoretical and empirical literature of social capital, and then we used fuzzy method for estimating time series of social capital. we used latent variable, because social capital is a qualify variable. crime and participation indexes are two related variables with social ca...
