Gully erosion found to be typical erosion form in semiarid and arid landscape. Because of the importance of this phenomenon, various studies have been conducted around the world to assess gully erosion and its effects. The purpose of this research was accuracy assessment of gully erosion susceptibility maps using SVM and MARS models in the Shazand watershed. Acquiring information about the gull...

most specialists in the field of foreign language teachingconsiderreading skill as an interactive process between the reader’s prior knowledge and the text.accordingly, the activation of prior knowledge for an effective comprehension is very important. it is generally agreed that the pre-reading phase is the stage where this type of interaction and activation may be enhanced throughcertain stra...

Figure 1 Frozen activation map of atrioventricular node reentrant tachycardia (AVNRT), with yellow representing earlier activation “colliding” with late (purple) activation along the slow pathway region (using CS 5–6 as reference). The map shows the portion of activation illustrated (rainbow segment) out of the entire mapped cycle length (maroon circle). There is a slow-pathway potential noted ...

Frost tolerance is the ability of plants to withstand freezing temperatures without unrecoverable damage. Measuring frost involves various steps, each which will vary depending on objectives study. This systematic map takes an overall view literature that uses measuring techniques in gymnosperms, focusing mainly conifers. Many different have been used for testing, and there has little change me...

The goal of this paper is to present a methodology for the computation invariant tori in Hamiltonian systems combining flow map methods, parameterization and symplectic geometry. While methods reduce dimension be computed by one (avoiding Poincaré maps), cost single step derived Newton-like method proportional FFT. Symplectic properties lead some magic cancellations that make work. multiple sho...

the mathematical aspect of cartographic mapping is a process which establishes a unique connection between points of the earth’s sphere and their images on a plane. it was proven in differential geometry that an isometric mapping of a sphere onto a plane with all corresponding distances on both surfaces remaining identical can never be achieved since the two surfaces do not possess the same gau...
