Autonomous Charging and Battery Swapping for Unmanned Aerial Vehicles: A Review

Advanced Intelligent Systems, EarlyView.
This review evaluates major autonomous charging and battery swapping methods for unmanned aerial vehicles (UAVs) against a single question: how close each is to sustained unattended operation. Rather than ranking them by charging performance, it identifies the limitation that most restricts each method, and briefly outlines the supporting technologies ...

A Non‐Volatile Heterogeneous Quantum Dot III‐V/Si DFB Laser With Optical Memristive Behavior

Advanced Physics Research, EarlyView.
A heterogeneous quantum dot III‐V/Si DFB laser stores its own optical state. An ultrathin Al2O3 memristor at the III‐V/Si interface produces non‐volatile wavelength shifts of ∼46 pm and ∼17 dB peak power contrast with zero holding power. Combining coherent light generation and persistent memory in one device opens a path toward neuromorphic photonics ...

Departing from standard practices: Strategic application of value engineering in the anatomy laboratory to enhance formaldehyde extraction using high‐impact, low‐cost, and low‐maintenance solutions

Anatomical Sciences Education, Volume 18, Issue 3, Page 241-253, March 2025.
Abstract This study describes the process of developing a high‐impact, low‐cost, and low‐maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection ...

Broadband and high gain slot antenna with adjustable polarisation

, 2012
[[abstract]]This article presents a wide slot antenna whose polarization can be adjusted by rotating a conducting strip. To obtain an optimum gain of the slot antenna, a parasitic patch and a metallic reflector were placed at the front and rear of the ...

Multiple Impacts of Energy Efficiency Measures and Other Key Factors That Rule the Adoption: Insights From the Italian Wood and Metal Working Sectors

Business Strategy and the Environment, EarlyView.
ABSTRACT Energy efficiency is recognized as a cornerstone for industrial decarbonization, yet its uptake remains very limited in the manufacturing firms leading to energy efficiency gap. Whilst the low uptake of energy efficiency measures in industry is a well‐known issue, research has not sufficiently investigated the role of comprehensive factors in ...
