Entrepreneurship is a new phenomenon in Iran and the research on this subject especially in women entrepreneurship is very limited. In most of the entrepreneurship researchs, access to suitable financial and information resources, a balance between business and family, and attraction of the others' confidence have been considered among the women entrepreneurs' problems and obstacles in starting...

In this paper the Differential Evolution algorithm is deployed to the robotic path planning optimization problem for autonomous mobile vehicles. At this stage, the simulations consider the robot world with level surfaces and static obstacles , in which the optimization is performed off-line. The global objective is to evaluate the differential evolutionary algorithm in solving path planning pro...

Background and purpose: The new thrombolytic agents have opened a new horizon in the treatment of patients with stroke. However, the contraindication and delay in beginning of the drug have caused serious obstacles to apply this therapy. In this study we verified these obstacles in early beginning of thrombolytic treatment. Materials and methods: In this cross sectional study, we investigated ...

In path planning Problems, a complete description of robot geometry, environments and obstacle are presented; the main goal is routing, moving from source to destination, without dealing with obstacles. Also, the existing route should be optimal. The definition of optimality in routing is the same as minimizing the route, in other words, the best possible route to reach the destination. In most...

In this paper we study fully nonlinear obstacle type problems in Hilbert spaces. We introduce the notion of Q-elliptic equation and prove existence, uniqueness, and regularity of viscosity solutions of Q-elliptic obstacle problems. In particular we show that solutions of concave problems with semiconvex obstacles are in the space W 2,∞ Q .
