Abstract Recently, high‐entropy perovskite oxides (HEPOs) have received increasing interest for energy storage applications owing to their unique structure, huge composition space, and promising properties. However, designing HEPOs with improved performance remains a challenge. In this study, various were designed by partially replacing Zr 4+ Ti in (Bi 0.4 Ba 0.2 K Na )TiO 3 medium‐entropy ferroelectric ceramics. The resulting ceramics exhibited pseudo‐cubic structure. With content, the...
Abstract The liquid phase screening method was used to search for sintering aids 0.88(Bi 0.4 K 0.2 Na Ba )TiO 3 –0.12Sr(Mg 1/3 Nb 2/3 )O ceramics. efficiency of the tested by studying effect three selected oxides on densification and properties results showed that all can improve ability energy storage performance. sample with 1.5 mol% SiO 2 exhibited a recoverable density 2.61 J/cm 77.4% at an electric field 270 kV/cm, indicating its promising applications in low‐to‐moderate fields.
To the collection system optimal design of offshore wind farm, factors considered are not only reasonable configuration cable and switch, but also influence obstacles on topology farm. This paper presents a concrete optimization algorithm with obstacles. The minimal area rectangle encasing box obstacle is obtained by using method box. Then combining advantages Dijkstra Prim used to gain scheme avoidance path planning. Finally fuzzy comprehensive evaluation model based analytic hierarchy...
$k$-core is a subgraph where every node has at least $k$ neighbors within the subgraph. The subgraphs been employed in large platforms like Network Repository to comprehend underlying structures and dynamics of network. Existing studies have primarily focused on finding groups without considering their size, despite relevance solution sizes many real-world scenarios. This paper addresses this gap by introducing size-prescribed search (SPCS) problem, goal find specified size that highest...
This paper presents a novel perspective on the relationship between decentralization, prevalent characteristic of multi-agent systems, and centralization, which involves imposing central control to achieve system-level objectives. Specifically, within context networked opinion dynamic model, we introduce discuss framework for centralization. In this framework, decentralized network consists autonomous agents dynamic, unknown social structure. Centralization appointing specific in as access...
