Potential heuristics for state-space search are defined as weighted sums over simple state features. Atomic features consider the value of a single state variable in a factored state representation, while binary features consider joint assignments to two state variables. Previous work showed that the set of all admissible and consistent potential heuristics using atomic features can be characte...
in this research three-dimensional free vibration analysis of functionally graded circular plate with various boundary conditions is achieved. a semi-analytical method, which makes use of the state space method and the one-dimensional differential quadrature method, is used to obtain the vibration frequencies and dynamic responses of circular plates. numerical results are given to demonstrate t...
بیشتر مطالعات در زمینه تاثیر فن آوری اطلاعات و ارتباطات (ict) بر رشد اقتصادی در کشورهای توسعه یافته حاکی از اثر مثبت و معنی دار این فن آوری بر بهره وری و رشد اقتصادی در دهه 1990 است. برخی مطالعات چنین رابطه مثبتی را در کشورهای در حال توسعه نیز تایید می کنند، اما هنوز زمینه بررسی به خصوص در کشورهای در حال توسعه با توجه به ویژگی های نامتوازن و ضعیف زیرساختی شان وجود دارد. مقاله حاضر با استفاده از...
This paper gives an abstract sufficient condition on Riesz basis with parentheses property for the generators of C0-groups in Hilbert spaces whose eigenvalues are comprised of some finite unification of separable sets after taking the algebraic multiplicities into account. The condition is then applied to the closed-loop system of a serially connected string system under joint damping feedbacks...
is stable. For infinite-dimensional systems the situation is more complicated. Although the eigenvalues still possess the same property as in the finite dimensional situation, they don’t longer rule the stability. Since many years it is an open question whether the stability of (1.1) and (1.2) are equivalent. For Banach spaces it is not hard to find a counter example, and so we concentrate on t...
abstract the present thesis seeks to critically read george orwell’s nineteen eighty-four and animal farm in the light of louis althusser’s thought and theory. the present thesis proceeds to examine and demonstrate althusser’s major concepts including ideological state apparatuses (isas), repressive state apparatuses (rsas), the structure, the subject, and ideological interpellation which r...
Insight in the global structure of a state space is of great help in the analysis of the underlying process. We advocate the use of visualization for this purpose and present a new method to visualize the structure of very large state spaces. The method uses a clustering method to obtain a simplified representation, which is used as a backbone for the display of the entire state space. With thi...
