Optimal sizing of C-type passive filters under non-sinusoidal conditions [PDF]

, 2014
In the literature, much attention has been focused on power system harmonics. One of its important effects is degradation of the load power factor. In this article, a C-type filter is used for reducing harmonic distortion, improving system performance ...

Real power loss minimization using interior point method

International Journal of Electrical Power & Energy Systems, 2001
Abstract An efficient predictor–corrector primal–dual interior point method (IPM) is applied to reactive power optimization. A linear model is introduced in which control variables and voltage increments are linked by a modified Jacobian matrix, and transmission losses are represented as a function of voltage increments.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

A Majorization-Minimization Approach to Design of Power Transmission Networks

, 2010
We propose an optimization approach to design cost-effective electrical power transmission networks. That is, we aim to select both the network structure and the line conductances (line sizes) so as to optimize the trade-off between network efficiency ...
