employees always concern about losing their job , or in other word , losing their income resources. for this purpose, every government requires strong system for covering these concerns. the unemployment insurance (ui) program’s can be used for achieving this goal. in this thesis, we price ui based on the insurance history of employee and the duration of being unemployed. we use the weibull dis...
chapter one is devotod to collect some notion and background informations, which are needed in the next chapters. it also contains some important statements which will be proved in a more general context later in this thesis. in chapter two, we show that if the marginal factor-group is of order np1...pk,n>1, then we obtain a bound for the order of the verbal subgroup. also a bound for the bear-...

We describe an efficient procedure for sampling representatives from a weighted set such that for any weightings S and T , the probability that the two choose the same sample is equal to the Jaccard similarity between them: Pr[sample(S) = sample(T )] = ∑ x min(S(x), T (x)) ∑ x max(S(x), T (x)) where sample(S) is a pair (x, y) with 0 < y ≤ S(x). The sampling process takes expected computation li...
Abstract: Background:Blended learning is a term increasingly used to describe the way e-learning is being combined with traditional classroom methods and independent study to create a new, hybrid teaching methodology. The aim of this study was to explore the perspectives of Tabriz health center staff on the Establishment status of blended learning system based on ISO 10015 requirements. Methods...
Let {X 1 , · · · , X N } be a set of N independent random variables, and let S n be a sum of n random variables chosen without replacement from the set {X 1 , · · · , X N } with equal probabilities. In this paper we give a one-term Edgeworth expansion of the remainder term for the normal approximation of S n under mild conditions.
Let $S= \{e_1,\,e_2, \ldots,\,e_m\}$ be an ordered subset of edges of a connected graph $G$. The edge $S$-representation of an edge set $M\subseteq E(G)$ with respect to $S$ is the vector $r_e(M|S) = (d_1,\,d_2,\ldots,\,d_m)$, where $d_i=1$ if $e_i\in M$ and $d_i=0$ otherwise, for each $i\in\{1,\ldots , k\}$. We say $S$ is a global forcing set for maximal matchings of $G$ if $...
Introduction: Blended learning is a combination of systemic and contingency approaches to learning which means that besides paying attention to the relationships between all components as a whole, the conditions of utilizing these tools to achieve the best results are especially taken into account too. The aim of this study was to explore the perspectives of Sarab health and treatment network s...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
