There are two important aspects to good injector performance in rocket engines—the atomization performance (droplet size and distribution, for example) and uniformity of operation (even distribution of droplets in time and space). In general, both of these aspects are affected by the geometry and operating conditions of the injector. In studying atomization performance, prior work has largely f...

We return today to property testing and a surprising application of F2 estimation (or equivalently `2-norm approximation) for the problem of testing the closeness to uniform of a probability distribution. We consider discrete distributions on the domain [n]. Each such distribution is given by a probability vector p = (p1, . . . , pn). The uniform distribution U on [n] has Ui = 1/n for all i ∈ [...

UNLABELLED Uniformity testing is performed daily to ensure adequate camera performance before clinical use. The aim of this study is to assess the reliability of Beth Israel Deaconess Medical Center's locally built, centralized, Web-based uniformity analysis system by examining the differences between manufacturer and Web-based National Electrical Manufacturers Association integral uniformity c...

In this thesis, we step inside an unexplored region of Wireless Sensor Networks (WSNs) research. Nowadays, almost all WSNs research relies upon a hidden uniformity assumption. This assumption involves deployment, distribution and radio transmissions. Unfortunately, the real world is not uniform. In the thesis, we break the uniformity assumption and study the non-uniformity influence in WSNs. In...

chemical vapor deposition (cvd) is one of the most important methods for producing carbon nanotubes (cnts). in this research, a numerical model, based on finite volume method, is investigated. the applied method solves the conservation of mass, momentum, energy and species transport equations with aid of ideal gas law. using this model, the growth rate and thickness uniformity of produced cnts,...
