This paper proposes Design and Implementation of CORDIC algorithm for Direct Digital Synthesizer. COordinate Rotation DIgital Computer (CORDIC) algorithm is an interesting technique for phase to sine amplitude conversion. The algorithm proposed in this design is to utilize dynamic transformation rather than ROM static addressing. The proposed CORDIC design is based on Pipeline data path Archite...

As research in alternate energy sources is growing, solar radiation catching the eyes of community immensely. Since generation depends on uncontrollable natural variables, without proper forecasting, this source cannot be trusted. For use machine learning algorithms one best choices. This paper proposed an optimized forecasting ensemble model consisting pre-processing and training phases. The p...

We introduce two sine and cosine types of generating functions in a general case apply them to the classical hypergeometric orthogonal polynomials as well some widely investigated combinatorial numbers such Bernoulli, Euler Genocchi numbers. This approach can also be applied other celebrated sequences.

This paper argues in favor of a specific type of confidence for use in computer-aided diagnosis and disease classification, namely, sine/cosine values of angles represented by points on the unit circle. The paper shows how this confidence is motivated by Chinese medicine and how sine/cosine values are directly related with the two forces Yin and Yang. The angle for which sine and cosine are equ...

Abstract The primary object of study is the “cosine-sine” functional equation f ( xy ) = x g y )+ h for unknown functions f, g, : S → ℂ, where a semigroup. name refers to fact that it contains both sine and cosine addition laws. This has been solved on groups semigroups generated by their squares. Here we find solutions larger class discuss obstacles finding general solution all semigroups. Exa...

Coordinate Rotation Digital Computer (CORDIC) algorithm is an established method in complex arithmetic function discovery using shift and add operations. An absolute Scaling-free CORDIC algorithm for cosine and sine function computation function has been implemented. A combination of third order approximation Taylor series and leading-one-bit detection algorithm has been adopted in this impleme...

The radix-2 decimation-in-time (DIT) fast Hartley transform algorithm for computing the Discrete Hartley Transform (DHT) was introduced by Bracewell. DIT and decimation-in-frequency (DIF) algorithms were further developed by Meckelburg and Lipka, Prado, Sorenson et al, Kwong and Shiu. In these algorithms, the stage structures perform all the additions and multiplications and utilize stage depen...
