the rate of soil erosion and sediment yield estimation in the catchment areas is considered as an important factor for soil and water conservation practices. due to difficulties and restrictions in common soil erosion methods, applying a high accuracy method with lowest cost and time consuming would be necessary. assessment of soil loss in hilly areas with capacity of rang land that has changed...

This research was aimed to simulate and prioritize the effective factors on water erosion using USLE-M in the system dynamic model. In this integrated model, by using the system dynamic simulation software (Vensim), all variables and factors involved in erosion and soil loss were considered according to the USLE-M model. After model implementation, the estimated values and observations were com...

In this research, turbulent MHD convection of liquid metal with constant and variable properties is investigated numerically. The finite volume method is applied to model the fluid flow and natural convection heat transfer in a square cavity. The fluid flow and heat transfer were simulated and compared for two cases constant and variable properties. It is observed that for the case variable pro...

Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...

In this paper, we propose a new estimator: the Slope SVM, which minimizes the hinge loss with the Slope penalization introduced by [3]. We study the asymptotical behavior of the `2 error between the theoretical hinge loss minimizer and the Slope estimator. We prove Slope achieves a (k/n) log(p/k) rate with high probability and in expectation under the Weighted Restricted Eigenvalue Condition. T...

STUDY DESIGN Retrospective evaluation. PURPOSE To analyze the effect of T1 slope on degree of degeneration in patients with cervical disc degeneration. OVERVIEW OF LITERATURE The T1 slope is well known parameter that may be very useful in evaluating sagittal balance. There are no reports on the analysis of the relationship between T1 slope and cervical disc degeneration. We hypothesized tha...
