A Rapid Post‐Disaster Restoration Method for Networked Microgrids Based on Adaptive Quantum Particle Swarm Optimization

open access: yesEnergy Science &Engineering, EarlyView.
To enhance the power restoration speed of networked microgrids (NMGs) after extreme natural disasters and reduce the power outage of the system, this paper proposes a rapid post‐disaster restoration method for NMGs based co‐optimization of fault repair and load restoration.

Investigation and Evaluation of Wax Deposition Treatment Methods in Large Natural Gas Plants

open access: yesEnergy Science &Engineering, EarlyView.
Problem: Wax blockage (Biphenyl, PAHs) in low‐temperature units crippled plant capacity. Solution: A novel Circulating Light Hydrocarbon Injection technology. Mechanism: Light hydrocarbons disrupt wax crystals via “like dissolves like” and are continuously recovered. Outcome: 1. Throughput dropped from 10 MMscmd to 3 MMscmd 2.

Isometric Surface Method and Its Numerical Tests for Mixed-Integer Linear Programming

open access: yes, 2008
In this paper we solve mixed-integer linear programming including integer linear programming by isometric surface method under the MATLAB environment. The algorithm can quickly obtain the optimal mixed-integer point simultaneously using isometric planes ...

Donor‐acceptor fractal synergy: Decoding self‐similarity for stable organic photovoltaics

open access: yesFlexMat, EarlyView.
Morphological congruence between donor and acceptor refines the fractal structure of bulk heterojunction films and enhances their self‐similarity. This optimized multiscale morphology preserves charge‐transport pathways against external disturbances, suppresses structural degradation, and improves the operational stability of organic solar cells while ...

Mixed integer programming models for fire fighting

open access: yes
In this paper, a set of mixed integer programming (MIP) models to optimize the location of a set of resources when fighting fire is proposed. The MIP model integrates fire spread and the decisions relative to the resources location.Four problems are ...

Government affiliation and innovation in emerging market firms: The role of international diversification

open access: yesGlobal Strategy Journal, EarlyView.
Abstract Research Summary This study examines how international diversification interacts with government affiliation to shape innovation outcomes in emerging market firms. We reconceptualize government affiliation as a resource‐structuring mechanism that varies across hierarchical levels and influences the coherence of firms' dominant logics of ...

Brexit and Its Impact on EU Financial Markets

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the impact of Brexit on volatility spillovers across the EU countries. We introduce a Brexit intensity measure that assigns an intensity score reflective of the financial markets' reaction to the events that occurred as Brexit negotiations began to unfold.
