The coupled free vibration of liquid and its elastic cover, such as a plate or membrane, in three-dimensional rectangular tank is investigated through an analytical scheme based on the velocity potential theory for flow linear cover. For fluid domain, expanded into double cosine series along longitudinal transverse directions, respectively, with corresponding eigenvalues determined from imperme...

The technical merits of weak-value-amplification techniques are analyzed. We consider models of several different types of technical noise in an optical context and show that weak-value-amplification techniques (which only use a small fraction of the photons) compare favorably with standard techniques (which use all of them). Using the Fisher-information metric, we demonstrate that weak-value t...

The miniaturization of electromechanical transducers using bulk and surface micromachining processes has enabled the deployment of microelectromechanical systems (MEMS) in a variety of applications, from cell phones and ink-jet printers to drug delivery devices. A recently developed approach for the fabrication of multimaterial fiber devices presents a unique opportunity to realize MEMS in a no...

The advent of new electron accelerators with few-GeV beam energies makes the (e,ep) reaction a promising tool for investigating new aspects of the electromagnetic interaction. To this purpose it is crucial to set the scale of Final-State Interactions (FSI) at high ejectile energies. Usually, the problem is faced by mutuating wellestablished results of the Glauber method in the framework of elas...

The two current criteria for diagnosis of left anterior fascicular block (LAFB) were evaluated; they are marked left axis deviation (LAD) and a delay in the time of inscription of the intrinsicoid deflection (ID) in lead aVL asynchronous to V6. From 400 electrocardiograms with a LAD of --30 degrees or greater, 62 percent showed asynchronous activation of the left ventricle. There was only a gen...

In an effort to reduce the incidence of decubitus ulcers among wheelchair users, current work in cushion design concentrates on minimizing the pressure at the buttock-cushion interface. Finite element analysis can show the stress levels throughout the soft tissue between the cushion and the ischial tuberosity and give designers a better indication of the effects of a particular cushion. Finite ...

statement of problem: t-loop is one of the most popular closing loops in orthodontic profession. however its activation is in the contrary to bouschinger effect theory, since the formed bends would be opened during activation. the purpose of this study was to add a helix in a way to be more respondent to the bouschinger effect theory. objectives: to compare the load deflection, maximal elastic ...

Flanged shear walls are used extensively in moderate- and high-rise buildings to resist lateral loads induced by earthquakes. The seismic performance of many buildings is, therefore, closely linked to the behavior of the reinforced concrete walls. They must be carefully designed to provide not only adequate strength, but also sufficient ductility to avoid brittle failure under strong lateral lo...
