Voltage fluctuation is an essential problem exiting in distribution network. This paper applies Hilbert Huang transform (HHT) algorithm to dealing with voltage fluctuation tracking. An adaptive method based on waveform matching is presented to prevent the endpoint effects in mode decomposition. Numerical examples are given and the simulation verifies the practicality of the proposed method.

This letter points out that the main ideas and conclusions of the "The No-Prop algorithm" paper which has recently appeared in this journal were proposed earlier by G.-B. Huang et al. 10 years ago and intensively discussed and applied by other authors in the past 10 years.

In this paper, we describe improvements to the function field sieve (FFS) for the discrete logarithm problem in Fpn , when p is small. Our main contribution is a new way to build the algebraic function fields needed in the algorithm. With this new construction, the heuristic complexity is as good as the complexity of the construction proposed by Adleman and Huang [2], i.e Lpn [1/3, c] = exp((c ...

The epidermis is highly sensitive to retinoids, and vitamin A (retinol) is a critical factor in the regulation of skin cell differentiation and proliferation. Despite extensive knowledge of retinoid-mediated gene transcription effects on epidermal cells and evidence for retinoid-mediated suppression of carcinogenesis in skin, basic transport events, especially cellular uptake, of this vitamin r...

1. The algorithm. Huang [1] gives an algorithm for computing the powers of a triangular matrix where the diagonal elements are unique. However, in contrast to Huang’s algorithm, the method presented here has the unique advantage of producing the result in closed form, which shows explicitly how the behavior of any element of the matrix varies with varying powers of the matrix. Also, the closed ...
