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 sporozoites of theileria annulata invade bovine mhc ii cells, where they differentiate into schizonts. the later can immortalize and induce fundamental changes in their host cells. live attenuated vaccine is an important way of controlling t. annulata infection of cattle. production is by prolonged cultivation of macroschizont-infected cells. the mechanisms underlying this transformation ar...

this paper analyzes a linear system of equations when the righthandside is a fuzzy vector and the coefficient matrix is a crisp m-matrix. thefuzzy linear system (fls) is converted to the equivalent crisp system withcoefficient matrix of dimension 2n × 2n. however, solving this crisp system isdifficult for large n because of dimensionality problems . it is shown that thisdifficulty may be avoide...
