The overall goal of the research conducted in this paper is to develop next generation force feedback systems by combining novel Magnetorheological (MR) fluid based systems with microstructural analysis and advanced control system design. Two MR fluid based telerobotic systems are designed, prototyped and tested with medical applications. Force feedback control is employed to replicate in the m...

the shear strength and shear energy per unit area, as well as the force and energy required for picking flowers, are important parameters in the design and development of harvesting mechanisms. in this study, shear strength and shear energy per unit area of saffron (crocus sativus l.) stems were determined at different bevel angles and shear velocities. the force and energy required for picking...

In this paper, dissimilar resistance spot welding of AISI 1075 eutectoid steel to AISI 201 stainless steel is investigated experimentally. For this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. The effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...

Mobile ad hoc network (MANET) is a self configuring and self relating wireless network of mobile nodes connected devoid of wires. Due to their unique characteristics such as mobility, dynamic topology and lack of essential infrastructure support, security is more challenging in MANET. So, to enhance the security in MANET, we propose Enhanced Identity-Based Cryptography (EIBC), an efficient key ...

This paper presents the design of a body-powered voluntary closing prosthetic hand. It is argued that the movement of the fingers before establishing a grip is much less relevant for good control of the object held than the distribution of forces once the object has been contacted. Based on this notion, the configurations of forces on the fingers and the force transmission through the whole mec...
