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 ...

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 ...

Synergy‐based crop suitability assessment for agrivoltaics: An easy‐to‐use traffic‐light framework for temperate climates

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change and the growing demand for renewable energy are putting increasing pressure on land, as food production and solar power generation often compete for the same areas. In this study, we assessed which temperate‐region crops are best suited for agrivoltaics, a technology combining farming and solar electricity production on the same land. We
