soil and water assessment tool model, swat, uses different layers of watershed data which out of soil layer is the important one. soil layer data should be extracted from detailed soil maps. in most developing countries including iran, these detailed maps are not available except for irrigation districts and rarely for dry land farming areas and also for some strategic places of development pur...
Global navigation satellite system (GNSS) networks with multi-frequency data can be used to monitor the activity of Earth's ionosphere and generate global maps vertical total electron content (VTEC). This article introduces evaluates operational GFZ VTEC maps. The processing is based on a rigorous least squares approach using uncombined code phase observations, does not entail leveling techniqu...
this article deals with the issues associated with developing a new design methodology for the nonlinear model-predictive control (mpc) of a chemical plant. a combination of multiple neural networks is selected and used to model a nonlinear multi-input multi-output (mimo) process with time delays. an optimization procedure for a neural mpc algorithm based on this model is then developed. the p...
Analysis of finite, noisy time series data leads to modern statistical inference methods. Here we adapt Bayesian inference for applied symbolic dynamics. We show that reconciling Kolmogorov's maximum-entropy partition with the methods of Bayesian model selection requires the use of two separate optimizations. First, instrument design produces a maximum-entropy symbolic representation of time se...
This paper proposes a global multi-level thresholding method for image segmentation. As a criterion for this, the traditional method uses the Shannon entropy, originated from information theory, considering the gray level image histogram as a probability distribution, while we applied the Tsallis entropy as a general information theory entropy formalism. For the algorithm, we used the artificia...
Introduction: Agentic personality is defined as having a sense of responsibility in one's life. The belief that the person has control over their life decisions and is responsible for their consequences. The senseing of self-efficacy that one's is being able to overcome obstacles that hinder progress throughout life. This study investigates the psychometric properties of the Multi-Measure Agent...
Iran has an average of 5.5 KWh per square meter solar radiation and 300 sunny days per year on 90% of the land. Regarding this amount of solar radiation and the necessity for solar potential zoning for better efficiencies, drawing solar potential maps is essential. In this study, the monthly data of 39 synoptic of Iran meteorological stations over years (1991-2000) has been used as the input da...
the purpose of this study was to investigate the relationship between family functioning and marital adjustment humor couples are due to the nature and objectives of the research and application of methods for its implementation correlation was used. the study population consisted of all the couples in the city who uses random cluster sampling of 200 students were selected as sample. data from ...
introduction the chemical characteristic of groundwater as a major source of water supply for human life is an important factor in determining the usage of it for agriculture, industry and drinking. useful techniques and different methods of studying the chemical composition of groundwater such as correlation coefficient, descriptive statistics, factor analysis and cluster analysis provide an u...
