Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

open access: yesWind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

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

open access: yesCAAI 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.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

open access: yesHigh Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Deciphering unusually large modulations in two related organic hydroxy channel structures

open access: yesActa Crystallographica Section B, EarlyView.
Two related organic hydroxy‐channel compounds are shown to have unusually large structural modulations.The incommensurately modulated structures of two related organic hydroxy‐channel compounds [(R)‐1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐(octan‐2‐yl)urea, 1; 1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐octylurea, 2] have been determined and compared to the structure of a ...

Advancing fetal autopsy in cases of maceration: Underwater dissection technique and its forensic relevance

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Fetal autopsy remains essential for determining the cause of intrauterine death and for supporting clinical, genetic, and forensic evaluations. However, in cases of advanced maceration, autolysis severely compromises tissue integrity, often preventing adequate identification of anatomical structures and limiting the diagnostic and medico‐legal
