BiCMOS technology [1] offers both the high driving capability of bipolar devices and the high input impedance of CMOS devices. The potential of BiCMOS technology has been demonstrated in a variety of applications such as gate arrays [2], static RAMs [3], dynamic RAMs [4] and microprocessors [5]. One of drawbacks of the conventional BiCMOS process is that the integration density is rather low si...

W-beam systems utilize end-terminal anchorages to develop tension upstream and downstream of an impact event. However, the capacities of the anchorage components under impact loading are not well known. One such W-beam end anchorage system, the Midwest guardrail system (MGS) trailing-end anchorage, was evaluated using three dynamic component tests _ a soil foundation tube pull test, a breakaway...

Data broadcasting has been recognized as a very effective data delivery mechanism in mobile computing environments with an unlimited number of users and changing demand patterns. A fundamental server design issue is the scheduling algorithm needed for the construction of the broadcast program. In most situations, users require information before a certain time, and therefore the server scheduli...

The dynamic extraoral force analyzer (DEFA) was found to be capable of measuring linear deflection as a function of force created by a headgear. Ten standard nontorqued face-bows with a cervical and a high-pull direction were tested to determine the reliability of the DEFA. Statistical analysis showed the DEFA to be reliable and accurate in differentiating various directions and deflections of ...

Background: No single pharmacologic treatment has proven effective for the symptomatic management of progressive supranuclear palsy. Methods: We report a case of postural instability and falls secondary to PSP of the Parkinson's subtype and initial monotherapy with donepezil 10 mg daily for 3 months followed by a novel investigation of selegiline in combination for 6 additional months. Fall fre...

The influence of surface stress and small scale on the dynamic pull-in behavior of nano-bridges is investigated in this paper. For this purpose, the governing equation of motion is derived based on the modified couple stress theory and Homotopy Perturbation Method with an auxiliary term is employed to produce the approximate solution of nano-beam vibrations. The effects of actuation voltage, in...

Performance characteristic of an Unmanned Air Vehicle (UAV) is investigated using a newly developed heuristic approach. Almost all flight phases of any air vehicle can be categorized into trim and maneuvering flights. In this paper, a new envelope called trim-ability envelope, is introduced and sketched within the conventional flight envelope for a small UAV. Optimal maneuverability of the inte...

In order to overcome the loss of performances issue when scaling resonant sensors down to NEMS, it proves extremely useful to study the behavior of resonators up to large displacements and hence high nonlinearities. A comprehensive nonlinear multiphysics model based on the Euler-Bernoulli equation which includes both mechanical and electrostatic nonlinearities in the case of a capacitive doubly...
