We address the problem of drawing hypergraphs. We propose and evaluate a family of algorithms that transform a hypergraph drawing problem into a graph drawing problem. Each algorithm in the family relies on a different encoding of a hyperedge into a set of edges. The algorithms can then use any graph drawing algorithms. However, we here focus on the force-directed algorithms. We propose and dis...

In recent years, hydroforming process has been applied in different industries such as aerospace, automotive and military industries due to its advantages, such as high dimensional accuracy, capability of forming complicated parts and high drawing ratio. Hydrodynamic deep drawing with radial pressure is one type of hydroforming process. In this paper, forming of cylindrical cups in hydrodynamic...

Typically, a user can understand a clear textual description of a small amount of relational information. However, when dealing with large amounts of relational information, a vast amount of text quickly becomes cumbersome. Existing methods and techniques, for the visualization of relational information, tend to effectively deal with only relatively small data sets. Here we present methods to g...

Cluttered drawings of graphs cannot effectively convey the information of graphs. Two issues might cause node overlapping when one draws a picture of a graph. The first issue occurs when applying a layout algorithm for an abstract graph to a practical application in which nodes are labeled. The second is the changing of a node’s size in a dynamic drawing system. This paper presents two algorith...

Deep drawing process is one of the most applicable methods in producing industrial parts. In this process, the initial blank deforms to final product using a rigid punch and die. In this investigation, the effect of deep drawing process parameters of brass/steel laminated sheet composites on required forming force has been investigated. The process simulated using finite element method (FEM) an...

CNG vessels are used in many vehicles.  Mass production of CNG pressure vessels requires exact understanding of process effective parameters.  In this paper, the numerical analysis has been used to study the manufacturing parameters.  The entire manufacturing processes, including deep drawing, redrawing and ironing, of an aluminum liner sample of CNG pressure vessel (without spinning) have been...
