Accurate determination of the pull-in, or the collapse voltage is critical in the design process. In this paper an analytical method is presented that provides a more accurate determination of the pull-in voltage for MEMS capacitive devices with clamped square diaphragm. The method incorporates both the linearized modle of the electrostatic force and the nonlinear deflection model of a clamped ...

this paper analyses and compares the performances of business-to-business e-commerce data quality and service quality among the use of the ‘push’ and ‘pull’ models. rosettanet’s original partner interface processes use the ‘push’ model which suffers from data redundancy when the volume of business-to-business transaction increases. however, when the ‘pull’ model is used, although it reduces dat...

In order to characterize very weak adhesive surfaces, we have developed a quantitative test inspired by the Johnson, Kendall, and Roberts adhesion test for soft adhesives, which relies on the formation and then the rupture of a capillary bridge between the surface to be tested and a liquid bath. Both the shape and the kinetics of breakage of the capillary bridge for various coatings put into co...

In this paper, the effects of initial deflection on static and dynamic behaviors circular capacitive transducers are experimentally investigated. The obtained results in good agreement with numerical simulations. It is shown that has a major impact response resonator by shifting pull-in voltage, its increasing resonance frequency modifying bifurcation topology from softening to hardening behavi...

With the proliferation of wireless information applications and services, data broadcasting known from radio networks has become an important mechanism for mobile data access in wireless communication networks. Two data delivery techniques, push and pull, and their hybrid combination had been introduced to satisfy mobile user demands. However, most previous research efforts were elaborated upon...

The simplicity and low-overhead of random walks have made them a popular querying mechanism for Wireless Sensor Networks. However, most of the related work is of theoretical nature and present two important limitations. First, they are mainly based on simple random walks, where at each step, the next hop is selected uniformly at random among neighbors. This mechanism permits analytical tractabi...

Introduction The glenohumeral joint has a large range of motion, yet it is still stable. The joint consists of the intercalated joint surfaces of the humeral head and glenoid, along with the surrounding capsuloligamentous structures. Interaction between the capsuloligamentous structures and the articulating surfaces provides the basic static constraint of the joint. On the contrary, coordinated...

FEM-based preliminary structural sizing has been successfully carried out for a typical single-aisle wing box structure using MSC Nastran, by considering various load cases representing aircraft manoeuvres, engine loads, landing and ground handling conditions. The strength, buckling fatigue criteria have applied as the design constraints sizing. resultant total mass (static modal) behaviour of ...

The allocation of inventory ownership affects the inventory availability in a supply chain, which in turn determines the supply chain performance. In this paper, we consider a supplier-retailer supply chain in which the supplier starts production well in advance of the selling season, and the retailer is offered two ordering opportunities at different points in time. An early order is allowed b...
