Micro hole is the fundamental feature found in any device and its components. Hence this paper aims to produce micro holes using electrochemical micromachining (EMM). The existing machining techniques EMM for creating are associated with more overcut (OC). Hence, reducing OC enhancing rate (MR) essential. This aspires investigate effect of graphite electrode magnetic force on copper plate. Four...

The portfolio is a perfect combination of stock or assets, which an investor buys them. The objective of the portfolio is to divide the investment risk among several shares. Using non-parametric DEA and DEA-R methods can be of great significance in estimating portfolio. In the present paper, the efficient portfolio is estimated by using non-radial DEA and DEA-R models. By proposing non-radial m...

A connectionist model made up of a combination of RBF networks is proposed the model decomposes multivalued dependencies into local single valued functions theory and applications are presented

Abstract: In this paper, the forming process of a central hub by radial-forward extrusion is analyzed by using the finite element software, ABAQUS. Radial-forward extrusion is used to produce hollow parts that generally feature a central hub with radial protrusions. Effective design factors such as mandrel diameter, die corner radius, die fillet radius, mandrel corner radius, tube wall thick...

Collision detection of two objects plays an essential role for the machine tool automation. Although collision has been studied in applications like virtual reality, requires high precision to avoid overcut damage high-cost tools. The current tools is under soft-ware based computer numerical control (CNC), low computation capability which refrains CNC approach from real-time detection. In this ...

background: fractures of distal radius are one of the most common fractures seen by physicians and account for 20% of all fractures seen in the emergency room. various factors contribute in secondary displacement of fracture fragments after anatomic or near anatomic close reduction and cast immobilization in distal radius fractures. this study was designed to examine the correlation between rad...

background: radial movement of the arterial wall is a well-known indicator of the mechanical properties of arteries in arterial disease examinations. in the present study, two different motion estimation methods, based on the block-matching and maximum-gradient algorithms, were examined to extract the radial displacement of the carotid artery wall. methods: each program was separately implement...
