New detection of voltage sag based on phase angle analysis

open access: yes, 2011
Voltage sag compensator is very important in power quality. Its performance also depends on the types of sag detection techniques used. Sag detection technique determines the dynamic performance of a voltage-sag compensator.

FEWT: Frequency‐Enhanced Wavelet‐Based Transformer for Multimodal Wheeled Bimanual Manipulation

open access: yesSmartBot, EarlyView.
An embodied mobile bimanual robot learns dexterous manipulation skills through imitation learning with multimodal perception. The integration of vision, proprioception, and tactile sensing establishes a comprehensive perception–action loop, enabling the robot to continuously understand, interact with, and adapt to complex physical environments.

Adjustable speed drives susceptibility to voltage sag

open access: yes, 2008
Access is limited to UniMAP community.Voltage sags are probably the most important power quality problems affecting industrial and large commercial customers. These events are usually associated with a fault somewhere on the supplying power system.

Adhesive Protein Nanoparticles Control Emulsion Properties via Tunable Interdroplet Linking

open access: yesSmall, EarlyView.
In this study, pea protein nanoparticles were probed for their ability to link emulsion droplets. Experiments across multiple length scales showed that the nanoparticles form shear‐resistant links via bridging interactions from the thin film between droplets.

Low‐Voltage Pulsed GMA‐AM Application for Controlling Heat Input and Improving Deposition Quality of 309LSi Multilayered Structures

open access: yessteel research international, EarlyView.
This manuscript presents a study on the effects of parameter control of low‐voltage pulsed‐GMA‐AM application for producing 309LSi multilayered build‐ups, which can simultaneously lead to reduced heat input up to 32.1%, enable pulsed‐spray transfer, provide stable depositing conditions and preserve dimensional consistency, favoring fabrication of a 114‐

Serviceability reserves of historic reinforced concrete slabs implications for structural reuse

open access: yesStructural Concrete, EarlyView.
Abstract The transition to a circular economy in the construction sector requires reliable methods to assess whether existing reinforced concrete elements can be reused in new load‐bearing structures. A central question is whether slabs designed according to historical standards also meet today's serviceability requirements.
