Satellite antenna aperture is closely related to the quality factor (G/T value) of the earth station. The G/T value and satellite power demand, i.e. equivalent rent bandwidth, is a logarithmic linear relationship. So the value of equivalent rent bandwidth increases with the narrowing of antenna aperture.
In mathematics, in the area of harmonic analysis, the fractional Fourier transform (FRFT) is a family of linear transformations generalizing the Fourier transform.It can be thought of as the Fourier transform to the n-th power, where n need not be an integer — thus, it can transform a function to any intermediate domain between time and frequency.
Another common use of vectorized indices is a filtering operation. Consider a clipping operation of a sine wave where amplitudes larger than 0.5 are to be set to 0.5. Using S-Lang, this can be done by y = sin(x); y[where(abs(y)>0.5)] = 0.5;
About 68% of values drawn from a normal distribution are within one standard deviation σ from the mean; about 95% of the values lie within two standard deviations; and about 99.7% are within three standard deviations. [8] This fact is known as the 68–95–99.7 (empirical) rule, or the 3-sigma rule.
Even the use of the blackboard bold R being used to denote "the set of all real numbers" is just a convention that might be clarified by including a simple entry like "where R is the set of all real numbers" in a list of variable definitions.
Limited C++ set by design to keep usage easy and allow it to work on embedded platforms. C++ is buried in macros so the learning curve for C programmers is minimal. Ported to Symbian. Has a mocking support library CppUMock Criterion: Yes: Yes: Yes: Yes: Yes [49] MIT: Unit testing framework with automatic test registration. Supports theories and ...
Principal component analysis (PCA) is a linear dimensionality reduction technique with applications in exploratory data analysis, visualization and data preprocessing.. The data is linearly transformed onto a new coordinate system such that the directions (principal components) capturing the largest variation in the data can be easily identified.
Flowchart of using successive subtractions to find the greatest common divisor of number r and s. In mathematics and computer science, an algorithm (/ ˈ æ l ɡ ə r ɪ ð əm / ⓘ) is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation.
