Actor-network theory, which is considered as a development of socio-technical structuralism school, observes reservation and stability of networks containing personal and impersonal components such as individuals, organizations, communication software and hardware, and infrastructural standards by examination of socio-technical dimensions concurrently.The goal of this research is studying the i...

widespread usage of web technology provides an opportunity for business in order to use internet as the tool for management of electronic relationship with costumers. organizations that undertake expense of investment in this field, one of their primary purposes is improvement of satisfaction of costumers. for this reason, in most of organizations which use the system of electronic relationship...

abstract. the purpose of the present article is to determine the effect of knowledge management on organizational agility through the use of structural equations modeling in auto-parts manufacturing companies. for this purpose, along with the review of concepts such as organizational agility and knowledge management, the dimensions and capabilities of knowledge management and organizational agi...

differential transform method has been applied to solve many functional equations so far. in this article, we have used this method to solve wave-like equations. differential transform method is capable of reducing the size of computational work. exact solutions can also be achieved by the known forms of the series solutions. some examples are prepared to show theefficiency and simplicity of th...

solitary wave solutions to the broer-kaup equations and approximate long water wave equa-tions are considered challenging by using the rst integral method.the exact solutions obtainedduring the present investigation are new. this method can be applied to nonintegrable equa-tions as well as to integrable ones.

two main goals are being pursued in this paper. first, a brief summary of the structural optimization methods is presented. although most of these methods are general and are used in analysis and design of skeletal as well as continuous structures, discussion is more often directed towards the shape optimization .the second second goal of this paper is to present a new method for sensitivity an...

This article deals with the free in-plane vibration analysis of a frame with four arbitrary inclined members by differential transform method. Based on four differential equations and sixteen boundary and compatibility conditions, the related structural eigenvalue problem will be analytically formulated. The frequency parameters and mode shapes of the frame will be calculated for various values...

It is a common practice to complement a forecasting method such as simple exponential smoothing with a monitoring scheme to detect those situations where forecasts have failed to adapt to structural change. It will be suggested in this paper that the equations for simple exponential smoothing can be augmented by a common monitoring statistic to provide a method that automatically adapts to stru...

‎in this paper‎, ‎we present a new modification of chebyshev-halley‎ ‎method‎, ‎free from second derivatives‎, ‎to solve nonlinear equations‎. ‎the convergence analysis shows that our modification is third-order‎ ‎convergent‎. ‎every iteration of this method requires one function and‎ ‎two first derivative evaluations‎. ‎so‎, ‎its efficiency index is‎ ‎$3^{1/3}=1.442$ that is better than that o...
