Interpolation of the Standard Visibility Function with One Millimicron Steps

Visibility with One Reeection

We extend the concept of the polygon visible from a source point S in a simple polygon by considering visibility with two types of reeection, specular and diiuse. In specular reeection a light ray reeects from an edge of the polygon according to the rule: the angle of incidence equals the angle of reeection. In diiuse reeection a light ray reeects from an edge of the polygon in all inward direc...

determinant of the hankel matrix with binomial entries

abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
