Logarithmic Hyperbolic Cosine Adaptive Filter and Its Performance Analysis
IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2021The hyperbolic cosine function with high-order errors can be utilized to improve the accuracy of adaptive filters. However, when initial weight errors are large, the hyperbolic cosine-based adaptive filter (HCAF) may be unstable.

Cosine Similarity Based Line Protection for Large-Scale Wind Farms
IEEE transactions on industrial electronics (1982. Print), 2021In this article, power converters are used in the integrated wind farms and can change the fault characteristics of the power system. The conventional pilot protection suffers from low sensitivity, or even the risk of maloperation.

Integral Transforms and Special Functions, 1999
The cosine integral Ci(λx) and its associated functions Ci+(λx) and C(λx) are defined as locally summable functions on the real line and their derivatives are found as distributions. Some convolution products of these distributions and other functions are then found.

The discrete cosine transform (DCT) is a Fourier-related transform similar to the discrete Fourier transform (DFT), but using only real numbers. It is equivalent to a DFT of roughly twice the length, operating on real data with even symmetry (since the ...

Cosine: A Cloud-Cost Optimized Self-Designing Key-Value Storage Engine
Proceedings of the VLDB Endowment, 2021Wepresent a self-designing key-value storage engine, Cosine, which can always take the shape of the close to “perfect” engine architecture given an input workload, a cloud budget, a target performance, and required cloud SLAs.
