The influence of a coupled casing on the performance of a multistage compressor under inlet distortion conditions

AIP Advances, 2023
In order to increase the stalling margin of a compressor under different inlet conditions, especially under inlet distortion conditions, a new coupled casing processing structure is proposed in this paper.

Human‐Machine Mutual Trust Based Shared Control Framework for Intelligent Vehicles

Advanced Intelligent Systems, EarlyView.
This work introduces a bidirectional‐trust‐driven shared control framework for human‐machine co‐driving. The method models human‐to‐machine trust from intention discrepancies and Bayesian skill assessment, and machine‐to‐human trust from integrated ability evaluation.

Influence of slotted casing treatment with surface roughness and dimples on the performance of an axial flow fan

Cogent Engineering
A numerical analysis is conducted to assess the impact of slotted casing treatments, dimples, and surface roughness on the performance of an axial flow fan. Five configurations were evaluated: baseline (without any flow control), axial slots, axial slots

Artificial Intelligence in Autonomous Mobile Robot Navigation: From Classical Approaches to Intelligent Adaptation

Advanced Intelligent Systems, EarlyView.
Artificial intelligence (AI) is reshaping autonomous mobile robot navigation beyond classical pipelines. This review analyzes how AI techniques are integrated into core navigation tasks, including path planning and control, localization and mapping, perception, and context‐aware decision‐making. Learning‐based, probabilistic, and soft‐computing methods

Characteristics of Differential Entropy Generation in a Transonic Rotor and Its Applications to Casing Treatment Designs

Machines
Casing treatments improve compressor stability but often at the expense of compressor efficiency. In this study, the differential entropy generation rate (DEGR) was applied to both efficiency evaluation and stall margin estimation.

Navigating Whiteness in Australia's Anti‐Racism Movement: A Duoethnographic Inquiry by Women of Colour Scholars

Australian Journal of Social Issues, EarlyView.
ABSTRACT This paper applies Critical Race Theory (CRT) to explore how whiteness operates within Australia's anti‐racism movement as a structuring force that shapes discourse, practice and policy. Despite the anti‐racism movement offering crucial spaces for resistance and reform, it remains entangled in Australia's settler‐colonial present and systemic ...
