Reactive power optimization for power distribution networks using mixed-integer Second-order cone programming

Journal of Physics: Conference Series
Abstract The integration of a large number of Distributed Resources (DR) into the power distribution network presents significant challenges to the system’s reactive power and voltage control. This paper comprehensively considers the impacts of network losses, curtailment of renewable energy, and user electricity consumption experiences,

Volume Quantization with Flexible Singularities for Hexahedral Meshing

Computer Graphics Forum, EarlyView.
Abstract We present a novel algorithm for quantization and subsequent hexahedral mesh generation from seamless volumetric maps. Quantization is the process of choosing integers that represent the numbers of hexahedral elements to be placed in each region of the volume, and transforming the seamless map into an integer‐grid map matching that choice ...

maxRgain—An R Package for Maximising Genetic Gains in Polyclonal Selection

Plant Breeding, EarlyView.
ABSTRACT Polyclonal selection, which was developed in the context of ancient grapevine varieties, uses intravarietal variability to improve the resilience and sustainability of viticulture. Based on quantitative genetics and linear mixed models, this approach predicts genotypic effects to select a group of clones that, as a whole, satisfy target ...

Convex Optimization and PV Inverter Control Strategy-Based Research on Active Distribution Networks

Energies
Optimizing the operation of active distribution networks (ADNs) has become more challenging because of the uncertainty created by the high penetration level of distributed photovoltaic (PV). From the convex optimization perspective, this paper proposes a

Bayesian Inference for Multivariate Monotone Densities

Scandinavian Journal of Statistics, EarlyView.
ABSTRACT We consider a nonparametric Bayesian approach to estimation and testing for a multivariate monotone density. Instead of following the conventional Bayesian approach of imposing a prior that satisfies the monotonicity restriction, we place a prior on the step heights via binning and a Dirichlet distribution. The resulting posterior distribution

Vector‐Driven Projection and Backprojection

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Projection and backprojection are fundamental operators in tomographic image reconstruction. Existing approaches—namely pixel‐driven (PD), ray‐driven (RD), and distance‐driven (DD)—are subject to well‐known trade‐offs among interpolation artifacts, geometric flexibility, and computational cost. Purpose This study aims to introduce a
