प्रत्यूर्जता इसके अंग्रेजी अर्थ का उदाहरण

It can be calculated from the beam's vacuum wavelength λ0, the radius of curvature R of the phase front, the index of refraction n (n1 for air), and the beam radius w (defined at 1/e2 intensity), according to:.

Index of refraction .

The index of refraction (or refractive index) is a way of measuring the speed of light in a material.

A third analysis of Pendry's perfect lens concept, published in 2003, used the recent demonstration of negative refraction at microwave frequencies as confirming the viability of the fundamental concept of the perfect lens.

One of his many scientific contributions is the discovery of the curvature of light through atmospheric refraction.

“…the primary healthcare practitioners of the eye and visual system who provide comprehensive eye and vision care, which includes refraction and dispensing, detection/diagnosis and management of disease in the eye, and the rehabilitation of conditions of the visual system.

Walther further brought into prominence the effects of refraction in altering the apparent places of the heavenly bodies, and substituted Venus for the moon as a connecting-link between observations of the sun and stars.

Once again, Della Porta's De refractione optices has an entire book devoted to ‘De Iride et colore’, an attempt to arrive at an understanding of the rainbow.

Current double Gauss lenses can be traced back to an 1895 improved design, when Paul Rudolph of Carl Zeiss Jena thickened the interior negative menisci and converted to them to cemented doublets of two elements of equal refraction but differing dispersion in the Zeiss Planar of 1896 to correct for chromatic aberration.

Negative refraction of visible light was experimentally verified in an yttrium orthovanadate (YVO4) bicrystal in 2003.

With the diode implants, Parks is capable of energy projection, light refraction for invisibility and illusion generation.

BAK-4 barium crown glass has a higher index of refraction than BK7, and is used for prisms in high-end binoculars.

The drawback of rasterization is that non-local effects, required for an accurate simulation of a scene, such as reflections and shadows are difficult; and refractions nearly impossible to compute.

Loukaitis suffered from [and was taking A moon dog, moondog, or mock moon, (scientific name paraselene, plural paraselenae, meaning "beside the moon") is a relatively rare bright circular spot on a lunar halo caused by the refraction of moonlight by hexagonal-plate-shaped ice crystals in cirrus or cirrostratus clouds.

प्रत्यूर्जता इसके अंग्रेजी अर्थ का उदाहरण

Failing to do so, such as by treating the cases and selected controls as the original cohort and performing a logistic regression, which is common, can result in biased estimates whose null distribution is different from what is assumed.

Ways to account for the random sampling include conditional logistic regression, and using inverse probability weighting to adjust for missing covariates among those who are not selected into the study.

This is how noise manifests in econometrics (as well as poor interpretation of regressions, such as assuming correlation means causation).

Later it was found out that it is not the serum itself which provoke the tumour regression, but rather the enzyme asparaginase.

If correction for confounding variables in a regression model took place and was applied appropriately.

Confounding and regression analysis .

It is possible that all of these disparities are due to discrimination, but regression analysis allows us to account for variables that may explain differences.

After correction for the potentially confounding variables in a regression model, we should be able to tell if there is still an impact of group membership on the quantity of interest.

In regression analysis, the matrix M I - X(X'X)^{-1} X' is known to produce the residuals e from the regression of the vector of dependent variables y on the matrix of covariates X.

This is because M X_1 0, or in other words, the residuals from the regression of the columns of X_1 on X are 0 since X_1 can be perfectly interpolated as it is a subset of X (by direct substitution it is also straightforward to show that M X 0).

Idempotent matrices arise frequently in regression analysis and econometrics.

For example, in ordinary least squares, the regression problem is to choose a vector of coefficient estimates so as to minimize the sum of squared residuals (mispredictions) ei: in matrix form,.
