Based on the combination prediction method for the characteristic parameters prediction of power transmission and transformation equipment

open access: yesEnergy Reports, 2022
The safe and stable operation of power transmission and transformation equipment is the foundation of power grid safety, so the prediction of power transmission and transformation equipment fault is particularly important, and the prediction of the ...

A comparison of transformation models between geodetic reference frames: case study in Illizi region (Algeria)

open access: yesGeodesy and Cartography
The Illizi region is an important petroleum zone in Algeria, where various seismic surveys have been conducted. The merging of adjacent surveys is not possible due to incompatible data linked to the geodetic networks.

Can one determine cosmological parameters from multi-plane strong lens systems?

open access: yes, 2014
Strong gravitational lensing of sources with different redshifts has been used to determine cosmological distance ratios, which in turn depend on the expansion history.

Euler-type transformations for the generalized hypergeometric function r+2Fr+1(x) [PDF]

open access: yes, 2010
We provide generalizations of two of Euler’s classical transformation formulas for the Gauss hypergeometric function extended to the case of the generalized hypergeometric function r+2 F r+1(x) when there are additional numeratorial and denominatorial ...

Effects of Heating Rate and Strain Rate on Phase Transformation in Micro-Grinding [PDF]

open access: yesEPJ Web of Conferences, 2019
The phase transformation in the grinding process could have a significant impact on the processing performance of the products. Although grinding process can lead to high heating and strain rates, the current studies on the phase transformation typically

Transformation optics in orthogonal coordinates

open access: yes, 2008
The author proposes the methodology of transformation optics in orthogonal coordinates to obtain the material parameters of the transformation media from the mapping in orthogonal coordinates. Several examples are given to show the applications of such a

An extension of Saalschütz's summation theorem for the series r+3Fr+2 [PDF]

open access: yes, 2013
The aim in this research note is to provide an extension of Saalschütz's summation theorem for the series r+3Fr+2(1) when r pairs of numeratorial and denominatorial parameters differ by positive integers.

Parameter-Efficient Transformer Embeddings

open access: yesCoRR
Embedding layers in transformer-based NLP models typically account for the largest share of model parameters, scaling with vocabulary size but not yielding performance gains proportional to scale. We propose an alternative approach in which token embedding vectors are first generated deterministically, directly from the token IDs using a Fourier ...
