Estimation of Laminar Burning Velocities by Direct Digital Photography

Near-limit laminar burning velocities of microgravity premixed hydrogen flames with chemically-passive fire suppressants

Effects of chemically-passive fire suppressants on laminar premixed hydrogen flames were investigated by combined use of microgravity experiments and computations. The experiments used a short-drop freefall laboratory facility that provides at least 450 ms of 10 2 g. Near-limit laminar burning velocities were measured for outwardly propagating spherical stoichiometric hydrogen-air flames with v...

Innovative Use of Opsite Flexigrid™ for Digital Photography in Rhinoplasty

Standardization of photography in plastic surgery is fundamental for pre-operative surgical planning, comparative post-operative assessment, and demonstration of surgical results.1 In rhinoplasty, slight changes in patient or camera position can lessen nasal hump, vary nose size, and alter skin tension.2 In order to prevent these common errors, photographic standardization with high-quality equ...

Quantification of plume opacity by digital photography.

The United States Environmental Protection Agency (USEPA) developed Method 9 to describe how plume opacity can be quantified by humans. However, use of observations by humans introduces subjectivity, and is expensive due to semiannual certification requirements of the observers. The Digital Opacity Method (DOM) was developed to quantify plume opacity at lower cost, with improved objectivity, an...
