in this paper, to address the effect of reactor performance and configuration of biodiesel production on subsequent process parameters (including mass & energy consumption, required facilities etc.) two diverse biodiesel production processes (from plant oil) were implemented/designed using aspen hysys v7.2. two series reactors were taken into account in these designs where in the first and seco...

In this paper, transverse and longitudinal vibration of nonlinear plate under exciting of orbiting mass is considered based on first-order shear deformation theory. The nonlinear governing equation of motion are discretized by the finite element method in combination with Newmark’s time integration scheme under von Karman strain-displacement assumptions. For validation of method and formulation...

Abstract New technology such as 3D printing, robotic manufacturing, and the Internet of things can shorten production time mass customization (MC) products, enhance self-design fun consumers, improve channel integration connectivity. In this study, we examine impact MC waiting from purchase products on supply chain integration. We consider a consisting one manufacturer, retailer, customizer. Th...

in this work the general aspect and the behavior of a simplified theoretical model for studying mass isolated systems are investigated. the model is in the form of a dual mass model in a single storey arrangement. to find damping ratio and natural frequency of the system, non-classical eigen analysis has been performed on the model. later, time integration analyses subjected to different earthq...

This paper describes the application of process integration principles to the design of oil refineries hydrogen network. In this regard, a design hierarchy as well as heuristics and required guidelines are proposed. The recommended rules compensate lack of procedure to the design and make the design process easier. The guiding principles of the design are based upon pinch technology and ext...

Abstract We extend the auxiliary-mass-flow (AMF) method originally developed for Feynman loop integration to calculate integrals which also involve phase-space integration. The flow of auxiliary mass from boundary ( ) physical point $0^+$?> is obtained by numerically solving differential equations with respective mass. For problems two or more kinematical invariants, AMF can ...

Building data integration systems today is largely done by hand, in a very labor-intensive and error-prone process. In this paper we describe a conceptually new solution to this problem: that of mass collaboration. The basic idea is to think about a data integration system as having a finite set of parameters whose values must be set. To build such a system the system administrators construct a...

In this paper, the extended finite element method (XFEM) is employed to investigate the statics and vibration problems of cracked isotropic bars and beams. Three kinds of elements namely the standard, the blended and the enriched elements are utilized to discretize the structure and model cracks. Two techniques referred as the increase of the number of Gauss integration points and the rectangle...
