Feature Selection Based on Adaptive Particle Swarm Optimization with Leadership Learning. [PDF]

Comput Intell Neurosci, 2022
With the rapid development of the Internet of Things (IoT), the curse of dimensionality becomes increasingly common. Feature selection (FS) is to eliminate irrelevant and redundant features in the datasets. Particle swarm optimization (PSO) is an efficient metaheuristic algorithm that has been successfully applied to obtain the optimal feature subset ...

Overlapping community‐based particle swarm optimization algorithm for influence maximization in social networks

CAAI Transactions on Intelligence Technology, Volume 8, Issue 3, Page 893-913, September 2023., 2023
Abstract Influence maximization, whose aim is to maximise the expected number of influenced nodes by selecting a seed set of k influential nodes from a social network, has many applications such as goods advertising and rumour suppression. Among the existing influence maximization methods, the community‐based ones can achieve a good balance between ...

Optimal scheduling of prosumer's battery storage and flexible loads for distribution network support

IET Generation, Transmission &Distribution, Volume 17, Issue 7, Page 1491-1508, April 2023., 2023
A residential energy management system is proposed for the control of the battery system and the load shifting of a prosumer equipped with photovoltaic. The goal is the minimization of power exchange between the prosumer and the grid in order to achieve: (a) Reduction of grid power losses, (b) voltage profile improvement, and (c) the increase of ...

Hypervelocity impact phenomena of LPSO-magnesium alloys [PDF]

EPJ Web of Conferences, 2018
Hypervelocity impact phenomena of long period stacking ordered type magnesium alloys (LPSO-Mg) plates were examined at the impact velocities of 4 km/s and 6 km/s. Ejecta veil and external bubble of debris of LPSO-Mg were darker than those of aluminum alloy A6061-T6.

A new anodic properties evaluation indicator for the magnesium‐based anodes of magnesium‐air batteries: The apparent valence

International Journal of Energy Research, Volume 46, Issue 15, Page 24645-24653, December 2022., 2022
Summary Mg‐air batteries are promising energy storage systems to deal with the requirement of green usage, high energy density, and sustainable energy. This paper provides an in‐depth understanding of the energy loss mechanisms of Mg‐based anodes, followed by a proposed new anodic properties evaluation indicator, the apparent Mg valence, based on the ...

Grain‐Boundary‐Free Glassy Solid Electrolytes based on Sulfide Materials: Effects of Oxygen and Nitrogen Doping on Electrochemical Performance

Batteries &Supercaps, Volume 5, Issue 11, November 2022., 2022
Grain‐boundary‐free glassy solid electrolytes are successfully synthesized and the doping effects of oxygen and nitrogen in the sulfide dense glass electrolytes are investigated for the first time. The doped sample exhibits a critical current density of 1.8 mA cm−2 at 100 °C, and the strategies of further improving the electrochemical performance and ...

Synergetic deformation mechanisms in an Mg-Zn-Y-Zr alloy with intragranular LPSO structures

Journal of Magnesium and Alloys, 2023
Deformation kink is one of the important strengthening mechanisms of the long-period-stacking-ordered (LPSO) phase containing magnesium (Mg) alloys, while the deformation twin is generally suppressed.

Time Optimal Trajectory Planning Algorithm for Robotic Manipulator Based on Locally Chaotic Particle Swarm Optimization

Chinese Journal of Electronics, Volume 31, Issue 5, Page 906-914, September 2022., 2022
Optimal trajectory planning is a fundamental problem in the area of robotic research. On the time‐optimal trajectory planning problem during the motion of a robotic arm, the method based on segmented polynomial interpolation function with a locally chaotic particle swarm optimization (LCPSO) algorithm is proposed in this paper.

Study of an Mg90Y7Zn3 alloy (WZ73) in sodium chloride solution — An analysis by correlated polarization and climate chamber testing

Engineering Reports, Volume 4, Issue 7-8, July-August 2022., 2022
From the polarization tests, the expected increase in corrosion sensitivity was observed when the NaCl concentration increases and the critical sodium chloride concentration for pit initiation was notified in the range 10−4–10−3 mol/L. For NaCl concentrations higher than 10−4 mol/L, the corrosion attack at the WZ73 magnesium alloy is characterized by ...
