land degradation due to soil erosion has been well pointed out as one of the most serious ecological and economic problems that some such south asian countries including iran are faced with. although high investment has been made, particularly in introduction of soil conservational mechanical practices, the level of acceptance of these practices has been low and while a high rate of erosion con...

Initiated in 1972, the Landsat program has provided a continuous record of earth observation for 35 years. The assemblage of Landsat spatial, spectral, and temporal resolutions, over a reasonably sized image extent, results in imagery that can be processed to represent land cover over large areas with an amount of spatial detail that is absolutely unique and indispensable for monitoring, manage...

This inquiry is practical in nature. Researching children’s behavioral problems and family’s communication as a practitioner would give me worthwhile knowledge that I could use for practice. However, Kerlinger and Lee (1999) stated that the primary purpose of empirical research is theory. Solving an applied problem is not a sufficient or an appropriate reason to conduct empirical research. Empi...

It is not probable that many of you would be interested in the academic presentation of a method for finding the area of a given polygon, as you each have a system of your own which is probably mathematically acceptable. However, I might take the liberty of citing to you pages 300 and 301 in Engineering Surveys, Elementary and Applied, by Rubey, Lommel, Todd, where you will find a good discussi...

The saturation-based reasoning methods are among the most theoretically developed ones and are used by most of the state-of-the-art first-order logic reasoners. In the last decade there was a sharp increase in performance of such systems, which I attribute to the use of advanced calculi and the intensified research in implementation techniques. However, nowadays we are witnessing a slowdown in ...
