Generalized linear‐constrained optimal power flow for distribution networks

open access: yesIET Generation, Transmission & Distribution, 2023
Optimal power flow (OPF) plays an important role in the secure and economical operation of the distribution network. This paper proposes a novel generalized linear‐constrained optimal power flow (GLOPF) model for both radial and mesh distribution ...

Generative Model With Dynamic Linear Flow

open access: yesIEEE Access, 2019
Flow-based generative models are a family of exact log-likelihood models with tractable sampling and latent-variable inference, hence conceptually attractive for modeling complex distributions. However, flow-based models are limited by density estimation

Coal flow volume measurement based on linear model partitioning

open access: yesGong-kuang zidonghua, 2023
The precision and computational efficiency of coal quantity measurement for belt conveyors based on linear laser stripes are low. There is a trailing phenomenon during belt operation, as well as data misalignment caused by deviation and drifting.

Linear and non-linear flow mode in Pb–Pb collisions at sNN=2.76 TeV

open access: yesPhysics Letters B, 2017
The second and the third order anisotropic flow, V2 and V3, are mostly determined by the corresponding initial spatial anisotropy coefficients, ε2 and ε3, in the initial density distribution.

Linear Stability of a Combined Convective Flow in an Annulus

open access: yesFluids, 2023
Linear stability analysis of a combined convective flow in an annulus is performed in the paper. The base flow is generated by two factors: (a) different constant wall temperatures and (b) heat release as a result of a chemical reaction that takes place ...
