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...

This paper deals with the biomechanical analyse of the human eye with a complex numerical model. We present our three dimensional finite element model including the built-up parts, applied material and geometric properties. Hereupon we describe the subjects which we want to investigate with this 3D model, such as accommodation, presbyopia and so on. We highlight the accommodation problem of the...

The increasing number of protein 3D structure information available makes the high-quality visualisation of this information play a more and more important role. Beside element-based representations the secondary-structurebased representation – also called cartoon representation – refers to a higher level of abstraction, representing the protein structure as tubes and ribbons. We present a meth...

existence of cracks in industrial structures is one of the important causes of their failure, especially when they are subjected to important axial compressive forces that might lead to buckling. therefore, it must be considered in stress analysis and designing and loading of such structures. in this paper, the buckling and post-buckling behaviors of stainless-steel cracked plates under axial c...

We describe tensor product type techniques to derive robust solvers for anisotropic elliptic model problems on rectangular domains in R d. Our analysis is based on the theory of additive subspace correction methods and applies to nite-element-and prewavelet-schemes. We present multilevel-and prewavelet-based methods that are robust for anisotropic diiusion operators with additional Helmholtz te...

We study numerical approximations for geometric evolution equations arising as gradient flows for energy functionals that are quadratic in the principal curvatures of a two-dimensional surface. Beside the well-known Willmore and Helfrich flows we will also consider flows involving the Gaussian curvature of the surface. Boundary conditions for these flows are highly nonlinear, and we use a varia...

Behavioural economists have employed beauty contest games in order to test for agents’ depth of reasoning. In multi-player beauty contest games, fully rational players should all bid zero. In experiments, it is observed that average bids are consistently much greater than zero, which may reflect a population of players consisting of a combination of full and bounded rationality. In contrast, in...

The search for beauty and its value has been a discussion topic since the ancient Greeks composed their myths. The advent of safer and more advanced modern plastic surgery techniques and the spread of aesthetic medicine have renewed the search for beauty. Today, beauty seems possible, accessible, and more demo­ cratic than ever before [1]. To be beautiful is going to become an imperative, and f...

In a standard visual marking experiment, observers are presented with a display containing one set of elements (old elements) followed after a certain time interval by a second set of elements (new elements). The task of observers is to search for a target among the new elements. Typically, the time to find the target depends only on the number of new elements in the display and not on the numb...
