Geometrically rational real conic bundles and very transitive actions [PDF]

, 2009
In this article we study the transitivity of the group of automorphisms of real algebraic surfaces. We characterize real algebraic surfaces with very transitive automorphism groups.

Real-time microgrid economic dispatch based on model predictive control strategy

Journal of Modern Power Systems and Clean Energy, 2017
To deal with uncertainties of renewable energy, demand and price signals in real-time microgrid operation, this paper proposes a model predictive control strategy for microgrid economic dispatch, where hourly schedule is constantly optimized according to

Conic Multi-Task Classification

, 2014
Traditionally, Multi-task Learning (MTL) models optimize the average of task-related objective functions, which is an intuitive approach and which we will be referring to as Average MTL. However, a more general framework, referred to as Conic MTL, can be

Degenerate conic anchoring and colloidal elastic dipole-hexadecapole transformations

Nature Communications, 2019
The recently discovered elastic hexadecapole has been thought to result from a conic anchoring condition. In order to understand it at a fundamental level, the authors introduce a model for this anchoring in the context of a Landau-de Gennes free energy ...

On the Conic Convex Approximation to Locate and Size Fixed-Step Capacitor Banks in Distribution Networks

Computation, 2022
The problem of the optimal siting and sizing of fixed-step capacitor banks is studied in this research from the standpoint of convex optimization. This problem is formulated through a mixed-integer nonlinear programming (MINLP) model, in which its binary/
