Abstract We consider a free boundary problem in an exterior domain $$\begin{aligned} {\left\{ \begin{array}{ll} Lu=g(u)&{}\text {in }\Omega \setminus K,\\ u=1 &{} \text {on }\partial |\nabla u|=0 &{}\text \Omega , \end{array}\right. } \end{aligned}$$ L...

in this research, the methodology of which is descriptive-inferential, our problem is the role of the unity of divine acts in mulla sadra’s transcendent philosophy and the evaluation of his arguments on it. in this regard, after explaining the concept of “unity of divine acts”, we show that since the boundaries of sadra’s philosophical system approaches speculative mysticism, sadra’s system in ...

In this paper, the effect of anisotropy on the free vibration of laminated rectangular plate supporting a localized patch mass is investigated. The two variable refined plate theory is applied to define the third order displacement field of a composite rectangular plate. The plate is considered to have simply supported boundaries. The equations of motion for rectangular plate are obtained by ca...

This paper concerns with free form surface reorganization and assessment of free formmodel complexity, grouping particular surface geometrical properties within patch boundaries, using self organized Kohonen neural network (SOKN). Neural network proved itself as an adequate tool for considering all topological non-linearities appearing in free form surfaces. Coordinate values of point cloud dis...

the application of ai-li alloy in aerospace and aircrafts industries have a promising future due to its lower density and a comparatible mechanical properties to the other aluminum alloys. the major problems encountered with parts made of al-li alloys, include segregation and brittleness. the presence of a precipitation free zone (pfz) and also the concentration of some elements such as k,na,o,...
