In practice, two forms of the acoustic wave equation, the velocity-stress and pressure forms, are used to simulate seismic experiments. These equations in their discrete forms lead to two families of finite difference ...

We investigate the problem of inferring elastic moduli of nonlinearly elastic membranes from interior measurements of deformation and pressure. We begin by formulating a model of membrane deformation under a vertical force ...

The current investigation examined the consistency of two different types of procedural knowledge as measured by a single-response Situational Judgment Test (SJT) across three different professions, including those of a ...

The HAVA (Help America Vote Act) mandated that all polling places provide privacy and independence to voters. DREs (Direct-Recording Electronic voting systems) have been assumed to be the solution to providing accessible ...

The lac operon has been key in the study of genetic regulation. Consisting of three structural genes and a regulatory domain, the lac operon controls the manufacture of lactose-digesting enzymes in E. coli bacteria. The ...

A review of the key concepts in the operation of a drift chamber are given. The equations governing charge division are developed. In order to optimize the chamber geometry, calculations were performed so that a suitable ...

An ultra high vacuum chamber was constructed to study thin film growth using scanning tunneling microscopy (STM). The sample stage is specially designed so that samples can be transferred in situ among various film preparation ...

Many applications call for a design that maximizes the rate of energy decay. Typical problems of this class include one dimensional damped wave operators, where energy dissipation is caused by a damping operator acting on ...

Rumination is a common mental experience that has received relatively little attention with respect to its precise dimensionality. The current research identifies seven such dimensions in the newly developed Survey of ...
