Reflecting wave forms the so-called water rays, which do not touch the bottom and the surface of the ocean. The conditions of occurrence of the water rays are following. The sum of the angles of the incident and refracted waves (rays) should be a right angle, and the tangent of the ...
The x-axis of the MTF curve depicts resolution. Resolution can be thought of from two perspectives: as seen from the object or from the sensor. Resolution from the object’s perspective is the smallest possible object that a lens can image. However, MTF curves do not reflect this definition...
A method for providing a spectacle ophthalmic lens to a wearer, the method comprising the following steps: providing a value, SV, representing the sensitivity of the wearer referred to a scale of sens
This is advantageously because the underlying surface may be close by and therefore representative of the position of the underlying surface underneath the body. Next, close to the edge the transparent material may be very thin. As such the lateral effect caused by refraction will be very small ...
Statistical mechanics are used to derive an approximate local equation of state for the fluid as a function of distance from the wall and to arrive at a wall rewetting criterion. The contact angle is a convenient parameter characterizing the liquid-solid interaction under these conditions. It is ...
A control sensor unit which outputs by sensing the angle of refraction and the position of the excavator arm is provided in each bending point of the excavator arm, the technical arrangement, one side of the excavator arm by the output of the control sensor unit the microcontroller outputs a ...
the curvature of the earth's surface and normal atmospheric refraction at radio frequencies and the range is determined by radio-location, is given by the equation h=5280d Sin alpha+5332d<2>, where h= height in feet, d =slant range in miles and alpha = angle of elevation in degrees....
The method of calculating the spectacle lens making use of the prescription data which depends on angle of visibilityAs for this invention, especially, being the method in order it calculates or to optimize the spectacle lens, or of being executed with the computer, The object distance A 11 ...
A total of 146 patients (146 eyes) with ACG complicated with cataract who underwent cataract surgery with atrial angle closure ≤180° were observed. All the patients were divided into 2 groups according to different intraocular lens calculation formula, with 73 cases in each group (73 eyes). ...
An incident angle when the electromagnetic waves enter the surface of the upper-layer dielectric slab and a refraction angle when the electromagnetic waves transmit out from the lower-layer dielectric slab are equal, thus a binary quartic equation set regarding transverse lengths of the propagation ...
