Robot path planning by integrating improved A* algorithm and DWA algorithm

Journal of Physics: Conference Series, 2023
Abstract Traversing many nodes, low search efficiency, path slanting through obstacles, many path redundancy points, and the inability of dynamic real-time obstacle avoidance are all typical problems of A* algorithm. In this paper, A robot path planning method combining improved A* algorithm and DWA algorithm is proposed.The ratio of the

Dissimilar Electrolyte Decouples Zn and MnO2 Redox Chemistry Enabling Dual‐Electrode‐Free Lean‐Electrolyte Batteries

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
While dual‐electrode‐free Zn‐MnO2 batteries offer high voltage, intrinsic safety and simple manufacturing, their efficiency and stability are limited by incompatible Zn and MnO2 redox chemistries. This work introduces a dissimilar electrolyte architecture to decouple Zn and MnO2 reactions, endowing a dual‐electrode‐free and lean‐electrolyte Zn‐MnO2 ...

SiC/Si ceramic hollow fibres: A new approach to Chlorella vulgaris biomass harvesting

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Efficient harvesting of microalgae is a critical challenge for the viability of biorefineries, requiring technologies that combine high selectivity, low cost, and scalability. The current work evaluated the performance of an asymmetric hollow fibre ceramic membrane (HF‐SiC70Si30), fabricated by phase inversion and sintered at 1250°C, in the ...

Learning Networks Drive Environmental Innovation: Evidence From Fourth‐Stage Purification Diffusion

Environmental Policy and Governance, EarlyView.
ABSTRACT Contaminants of emerging concern, including pharmaceuticals and industrial chemicals, threaten water quality globally. In the European Union (EU), until the adoption of the revised Urban Wastewater Treatment Directive in 2024, a regulatory gap had left the member states and the municipalities in them without binding removal standards ...

Research on Unmanned Vehicle Path Planning Based on the Fusion of an Improved Rapidly Exploring Random Tree Algorithm and an Improved Dynamic Window Approach Algorithm

World Electric Vehicle Journal
Aiming at the problem that the traditional rapidly exploring random tree (RRT) algorithm only considers the global path of unmanned vehicles in a static environment, which has the limitation of not being able to avoid unknown dynamic obstacles in real ...

Characterising City Scale Heat Climatology for Australian Climate Zones

International Journal of Climatology, EarlyView.
The Urban Heat Island (UHI) effect in Australian cities peaks at night, intensifying under dry conditions, clear skies, increased solar radiation, and low wind speeds. Long‐term observations show that nighttime temperatures in major cities have warmed faster than their rural surroundings and future climate projections fail to capture this disparity ...
