A Novel Protection Scheme for Unbalanced Faults in Inverter Dominated Networks: A Computationally Efficient Algorithm for Entry-Level Relays

open access: yesIEEE Access
Microgrids are now a common practice in distribution systems to increase resilience and reliability. However, microgrid protection remains a critical challenge, considering its requirement to operate in both grid connected and islanded, and the ...

Full-Duplex Relaying in MIMO-OFDM Frequency-Selective Channels with Optimal Adaptive Filtering [PDF]

open access: yes, 2015
In-band full-duplex transmission allows a relay station to theoretically double its spectral efficiency by simultaneously receiving and transmitting in the same frequency band, when compared to the traditional half-duplex or out-of-band full-duplex ...

Extending Battery Usage Time of a Heavy‐Duty Mecanum‐Wheeled Autonomous Electric Vehicle Used in Iron–Steel Industry by Considering Wheel Slippage

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
It is a fact that slippage causes tracking errors in both longitudinal and lateral directions which results to have less travel distance in tracking a reference trajectory. Less travel distance means having energy loss of the battery and carrying loads less than planned.

Design of Compact Liquid Crystal on Silicon Projection Optics Utilizing a Common Freeform Optical Path for Augmented Reality Displays

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a compact freeform projection optics using dual wedge prisms for waveguide displays. Unlike previous designs that separate illumination and imaging paths, a freeform optical path integrates both. The system achieves a 32º field of view, 37.5 pixels per degree, and a total volume of less than 2 cm3.

Crater Observing Bioinspired Rolling Articulator (COBRA)

open access: yesAdvanced Intelligent Systems, EarlyView.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

A Multimode Soft Robot Based on a Single Braided Tube

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a novel soft multimode robot based on a single braided tube directly formed and actuated by SMA wires with distinct initial configurations. By combining contraction, elongation, and bending deformations, the robot achieves straight crawling, turning, inchworm crawling, and rolling without additional actuators.

‘The System Can't Cope’: The Service System Response to Alcohol and Other Drug‐Facilitated Sexual Violence

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Alcohol and other drug‐facilitated sexual violence can have significant impacts on victim‐survivors, yet little is known about what support service providers offer them. To understand the experiences and perceptions of service providers, interviews with counsellors, health workers, forensic toxicologists and harm reduction workers were ...
