We exploit Bayesian criteria for designing an M/M/c//r queueing system with spares. This problem arises in many applications of the so-called machine interference problem, like job-shop type systems, telecommunication traffic, semiconductor manufacturing and transport. We exemplify our approach by a problem from aeronautic maintenance, where the numbers of repair crews c and spare planes s must...

Removal of fly ash using wet scrubbers is widely used in the small and medium scale industries. Among the wet scrubbing methods, spray column falls into the simplest type category for its simple construction and various advantages. A novel pilot plant wet scrubber has been conceived, designed and fabricated. This paper distinctly focuses on the detailed design and fabrication of the ejector, wh...

Silicon fusion bonding is studied as an enabling technology for the fabrication of microrobotic mechanisms. The e!ects of both surface activation technique and annealing temperature on bond strength are considered using a crack-opening technique. As part of the study, the relationship between patterned silicon feature size and the resulting bond strength is explored. Based on the experimental r...

an autonomous underwater vehicle (auv) with less noise and vortices as well as efficient power consumption, is pursued in this research by inspiration of shark swimming. design, hydrodynamic analysis, modeling, fabrication, navigation, and control of this novel auv is the main goal of this research. detailed explanation of the test and experiment with a brief overview on fabrication are provide...

This paper presents the design and a new low-cost process for fabrication of a second-order micromechanical filter using UV-LIGA technology. The micromechanical filter consists of two identical bulk-mode ring resonators, mechanically coupled by a flexural-mode beam. A new lumped modeling approach is presented for the bulk-mode ring resonators and filter. The validity of the analytical derivatio...

The application of porous bio-nanocomposites polymer has greatly increased in the treatment of boneabnormalities and bone fracture. Therefore, predicting the mechanical properties of these bio-nanocompositesare very important prior to their fabrication. Investigation of mechanical properties like (elasticmodulus and hardness) is very costly and time-consuming in experimental t...

In this study, the flow channels of a PEM fuel cell are fabricated by the EMM process. The parametric effects of the process are studied by both numerical simulation and experimental tests. For the numerical simulation, the multiphysics model, consisting of electrical field, convection, and diffusion phenomena is applied using COMSOL software. COMSOL software is used to predict the parametric e...

Abstract. This paper discusses the technological assumptions for production of helical metal expansion joint as a new type joints used to eliminate torsional deformations industrial pipelines. The method mechanically assisted laser forming, which was manufacturing technology, presented well. Furthermore, parameters and experimental results obtained during fabrication were presented. Mainly disc...
