more recently, titanium and aluminum alloys are gaining more interests to be implemented in hydro-forming applications. it is necessary to predict forming limits for these sheet alloys. forming limits play an important role in metal forming processes. forming limit diagrams, present the limit strains for various linear strain paths. in other hand, forming limit curve (flc), illustrates localize...

In this paper, we present an obstacle avoiding path planning method based on Voronoi diagram and composite Bezier curve algorithm which obtains the shortest path length. In our algorithm, a Voronoi diagram is constructed according to the global environment. The piecewise linear rough path in the Voronoi diagram which keeps away from the obstacles is obtained by performing Dijkstra’s shortest pa...

In this study, by recognizing geographical location changes of the sun-path diagram, we present a selection of sustainable architectural guidelines that influence the climatic element of sunshine. For this purpose, after the introduction of triple zones of the earth in terms of how the sun is exposed(include:Tropical, temperate and polar), the function of the earth's curvature to create geograp...

In this paper, we continue our study of the class of diagram groups. Simply speaking, a diagram is a labelled plane graph bounded by a pair of paths (the top path and the bottom path). To multiply two diagrams, one simply identifies the top path of one diagram with the bottom path of the other diagram, and removes pairs of “reducible” cells. Each diagram group is determined by an alphabet X, co...

We present an obstacle avoiding path planning method based on a Voronoi diagram. We use a tactical visibility measure to obtain the shortest path length with the lowest local probability to be discovered based on the map topology. A Voronoi-based navigation mesh for finding the shortest smooth path with the lowest visibility along the path is used. The piecewise linear rough path in the Voronoi...

Graph theoretic approaches plays important role in the path planning problems. The usefulness of Graph Theoretic approaches mainly the voronoi diagram is provided for the path planning in static and dynamic environment in this paper. Voronoi Diagram plays important role in computing the optimal path between the source & destination in static as well as dynamic environment. So, through the liter...

the design of tourist walkways and developments of strategies for more prolonged presence of people at ancientcontextures are considered as vivid multiple procedures in protecting of contexture, tour guiding and urbansustainability. shading in open spaces and pathways, especially in tourist areas, is one of the most important factorsin providing the thermal comfort perception. so in innovation ...

corporate image is an important organizational resource that enables to create, strengthen and sustain competitive advantage. different antecedents have been identified for corporate image in the literature including quality of products and services, consumer consideration or distribution system. green supply chain management appears to be an antecedent of corporate image too. this study examin...
