this article discuss about public policy implementation for cultural space in iran. we want to design a model for implementing cultural policy. and will explain the factors of the model and the relations between them. then we will compare the proposed model with the other famous models on the word. the proposed model created with the qualitative methodology which is grounded theory (gt). with p...

service oriented enterprises (soes) are subject to constant change and variation. in this paper, the changes are considered from an economic perspective based on service culture notion. once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. we construct a game theoretic model trying to capture the possible conflicting i...

Perceptual problems often call upon the application of a variety of knowledge sources. An automated problem solver can utilize much of this knowledge in the form of top-down guidance to improve accuracy and reduce processing time. Ironically, most automated hand-written character recognition systems, which are highly accurate, seldom use any top-down guidance. This paper describes an approach t...

Mountainous regions offer not only essential habitat and resources, including water, to the earth's more than 6 billion inhabitants, but also insights into how the global human habitat works, how it is being changed at the moment as global climates are disrupted, and how the disruption may lead to global biotic and economic impoverishment. At least 600 million of the earth's more than 6 billion...

We describe todolists (top-down skiplists), a variant of skiplists (Pugh 1990) that can execute searches using at most log2−εn +O(1) binary comparisons per search and that have amortized update timeO(ε−1 logn). A variant of todolists, called working-todolists, can execute a search for any element x using log2−εw(x)+ o(logw(x)) binary comparisons and have amortized search time O(ε−1 logw(w)). He...
