An important and fundamental issue in designing structured peer-to-peer networks is the tradeoff between the number of logical links and the number of hops. We present a flexible resource location protocol called K-Chord, for KC, which is based on the idea of proportional search. We conduct indepth study on KC. We show that KC achieves an excellent tradeoff between the number of logical links a...

Since its birth in 1995, Wiki has become more and more popular. This paper presents a Semantic Wiki, a Wiki extended to include the ideas of Semantic Web. The proposed Semantic Wiki uses a simple Wiki syntax to write labeled links which represent RDF triples. By enabling the writing of labeled links, Semantic Wiki may provide an easy-to-use and flexible environment for an integrated management ...

This paper presents a nonlinear formulation to model flexible-link robots based on finite element approach. To derive nonlinear dynamic equations of the flexible-link robot, links are modeled by some finite elements, and Lagrange’s principle is used for dynamic modeling. A local coordinate system is attached to each link and the local displacement of an arbitrary point is formulated based on no...

The development of a Wireless Sensor Network (WSN) gateway is challenging for countries where limited infrastructures lead to frequent power shortages and network unreliability. In this paper we describe the design of a flexible gateway that collects data from WSN, stores them in a database and makes them available via wireless links. In the design of such device, low power, low-cost and flexib...

The optimal path planning for two flexible cooperating manipulators carrying a solid object on a prescribed tip trajectory has been studied using kinematic resolution. The formulation has been derived using the Pontryagin minimum principle that results in a two-point boundary value problem. Also, a numerical technique based on converting the abstract optimization to parametric optimization prob...

The need for fast and precise robots in the industrial environment, capable of attending the productivity and quality demands and that allow a high volume of work, needs the usage of manipulators with flexible links. Besides this, aeronautic applications demand the usage of long and thin arms, which leads to remarkable structural changes. Therefore, the development of manipulators with structur...

Abstract: In present paper, a point to point optimal path is planned for a mobile manipulator with flexible links and joints. For this purpose, a perfect dynamic modeling is performed for mobile manipulators considering large deformation in links, shear effects, elastic joints, effect of gravitation, and non-holonomic constraints. To study large deformation of links, non-linear relation of disp...
