A novel chatter detection method for micro-milling based on 1D-CNN and SENet

Results in Engineering
The reliance on handcrafted features based on expert prior knowledge limits the adaptability and sensitivity of traditional chatter detection methods, especially under variable machining conditions. To address this limitation, a novel multi-stage chatter

Decentralized Electric Vehicle Charging Strategy for Voltage Regulation by Charging Shifting and Reactive Power Control in Distribution System

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
This paper proposes a decentralized electric vehicle (EV) charging control method designed to clear voltage violations in distribution grids with high EV penetration, while considering consumer convenience. The concentration of EV charging demand can cause localized voltage violations, posing a significant challenge to grid operation.

How weather got its words: a history of meteorological English – Part 1: Old English to the Age of Discovery

Weather, EarlyView.
The English language is a gargantuan, gluttonous beast. It has become extraordinary among its peers in its powers of assimilation – such that we rarely consider the diverse origins of the words we use. In this two‐part paper, we will explore these origins, including the Pontic‐Caspian steppe, the British Empire, latinophone scientists and a TV show. We

Suitable habitat of Himalayan wolf in Upper Mustang, Annapurna Conservation Area, Nepal

Wildlife Biology, EarlyView.
Decades ago, the Himalayan wolf Canis lupus chanco, a genetically distinct sub‐species of the gray wolf Canis lupus, faced persecution by local communities in the Nepalese Himalayas. Recently, wolf populations have returned and recolonized, sparking concerns about conflicts over livestock depredation, and emphasizing the urgent need for comprehensive ...

AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

The choice to submit: freedom, gender, and the figure of God in Pentecostal Nigeria Le choix de se soumettre : liberté, genre et figure divine chez les Pentecôtistes du Nigeria

Journal of the Royal Anthropological Institute, EarlyView.
Why do some women choose to submit to their husbands in marriage? In anthropology, the paradox of ‘chosen submission’ has famously been explored by Saba Mahmood. Her work amongst Egyptian women donning the veil in the Islamic da'wa movement spotlights the notion of ‘piety’ to explore how devotion to God can act as a powerful motivator of human ...

From Nouns and Adjectives to Verbs: Base Effects on the Grammatical Behaviour of Denominal Verbs in Ancient Greek1

Transactions of the Philological Society, EarlyView.
Abstract This paper investigates the role of semantic features of noun and adjective bases in determining the grammatical behaviour of Ancient Greek denominal and deadjectival verbs in *‐ye/o‐. The paper adopts a lexicalist framework (Rappaport Hovav & Levin 1998) and examines how the event schema, actionality, telicity and voice of derived verbs are ...
