Ophthalmic photography is a system of information transferral. In fundus photography, a visual description of the three-dimensional retinal and choroidal tissues is transferred to film. This twodimensional representation is used by the physician to make judgments concerning the health and treatment of the patient's retina. An accurate representation of the retinal and choroidal tissues is the g...

Extreme UV (EUV) lithography is the most advanced technology for creating patterns state-of-the-art Integrated Circuits (IC), with critical dimensions down to 10 nm. This resolution achieved by using a wavelength of 13.5 nm, imaging reflective reticle onto wafer via mirror-based projection system. The system uses low-pressure hydrogen background gas, which excited into low-density plasma energe...

The UIC Standard Suspension consists of a leaf spring (5) see the figure which rests on the axle box (6), which can move horizontally and vertically between the guidances (4). In the horizontal the guidance provides an end stop for the translations and the yaw of the wheelset (7). In the vertical direction the motion of the wheelset is restricted by the leaf spring with its nonlinear dry fricti...

On Tuesday, 6 May 1760, the Order of the Garter conducted the installation of a knight at Windsor Castle, outside London. A day of ceremony and festivity, participated in by a throng of knights, nobility, clergy, and others, ended with a splendid ball and supper.1 On Wednesday most of those who attended as well as numerous servants made their way back to London (1). Among the travelers were fou...

The BBP, BBP-type, Adamchik-Wagon, Chudnovsky's, and Ramanu-jan formulas of Pi are investigating by Mathematica. We point out errors of two BBP-like formulas.

This study investigated reconstruction techniques for building the instantaneous fuel regression rate of hybrid rocket motor (HRM). Specifically, an experiment in a laboratory 500 N-class with single-port wagon wheel grain, operated hydrogen peroxide (HP) and hydroxyl-terminated polybutadiene (HTPB) based (including Al), was carried out. A piece post-processing software developed to reconstruct...
