let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...

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.

in the first chapter we study the necessary background of structure of commutators of operators and show what the commutator of two operators on a separable hilbert space looks like. in the second chapter we study basic property of jb and jb-algebras, jc and jc-algebras. the purpose of this chapter is to describe derivations of reversible jc-algebras in term of derivations of b (h) which are we...

Background and Aim: Carriage of backpack sprayers is an inevitable part of agricultural operations that increases the risk of injury along with undesirable changes in walking mechanics. The purpose of this study is to formulate the muscle moment changes in the hip, knee and ankle for the backpack sprayer operator body. Methods: In this study, a seven-link sprayer operator model is designed and...

Sobel, Tenenbaum & Gopnik (2004) investigated the development of causal inferences in preschoolers in three experiments with tasks adapted from conditioning literature (backwards blocking and screening-off) and concluded from this indirect evidence that children develop a mechanism for Bayesian structure learning. It is proposed that (a) the differential performances in the two tasks are more l...

conclusions despite the higher frequency of s. aureus nasal carriage in the interns, compared to the first year students, the difference did not reach statistical significance. therefore, attendance at medical centers cannot be considered a risk factor for increasing carriage. results out of the 200 nasal swabs obtained, the overall nasal carriage of s. aureus was 24.5% (49/200). the prevalence...
