Electrostatically actuated microbeams have been studied by many researchers in the last few years. The aim of this study is to present an improved numerical analysis of the dynamic instability of a cantilever microbeam immersed in an incompressible viscous fluid. The finite element method is used for solving the vibrational equation of the microbeam and the potential functions of the fluids in ...

Inflation is an important phenomenon in the national economy, and central banks have made it one of their tasks to control inflation. The core research object this paper causes inflation China since entered 21st century, Entropy-weighting Method used construct a comprehensive indicator system, including 5 different factors contributing inflation, then analyze using VAR model. following conclusi...

the pull- out strength of the reinforcement has a significant role on the function of the most reinforced soil structures. since the coarse grain soils have a better interaction with the reinforcement, they are mostly used in these structures. in most situations, we have to transfer these granular soils from the borrow area, usually far from the site of the project. this will impose a considera...

Partial cross ownership (PCO) in a dyad supply chain refers to a situation where each firm holds a portion of its partner’s shares. We study this topic in push and pull supply chains, and prove that neither the supply chain’s nor any member’s profit changes with the percentage of the leader’s shares the follower holds. However, while the profits of the chain and the leader increase with the per...

Despite the consumers' increasing demand of technology-based innovations for making stores more appealing and the huge availability of advanced technologies, there is still a lack of research on the retailers' and employees' points of views towards the introduction of these systems. In fact, an efficient innovation should take care of both the final users/consumers' and the retailers/employees'...

Vol. 34 No. 5 • May 2009 • P&T® 243 (see the April issue of P&T, page 175). Ms. Levine sued and received a settlement from the clinic where the drug was administered. She also named Wyeth as a defendant, claiming that the drug’s label should have more clearly instructed clinicians against using an IV push injection. The label, which the FDA had approved, warned about inadvertent intra-arterial ...

We study the performance of a flexible manufacturing line producing multiple products under different material control strategies. Specifically, we compare the throughput versus average inventory characteristics when the line operates under pure pull and pure push strategies. Using simulation we show that the pure push strategy has a higher throughput for a given level of inventory than the pur...

described how the Internet enables a new supply chain paradigm, a push-pull paradigm that replaces the traditional push model. In the past, most companies operated by forecasting long-term demand, mass-producing inventories of product to fulfill the anticipated demand and then "pushing" the inventories on to the customer. The disadvantage of the push model is that production decisions are based...
