REWW‐ARM—Remote Wire‐Driven Mobile Robot: Design, Control, and Experimental Validation

open access: yesAdvanced Intelligent Systems, EarlyView.
The Remote Wire‐Driven robot “REWW‐ARM” demonstrates a new concept of remote actuation that separates electronics from harsh environments while retaining closed‐loop control. Combining tendon‐sheath mechanisms with decoupled joints, it achieves efficient power transmission and autonomous locomotion, manipulation, and underwater operation, suggesting ...

Facilitators and barriers to neighborhood social integration

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Social isolation has reached concerning rates, particularly in the wake of the COVID‐19 pandemic. Social integration is critical to combatting social isolation and loneliness by promoting a sense of community and belonging. Yet, most existing research centers on fostering close personal relationships within family and friend networks.

Prediction of Landing Gear Noise Reduction and Comparison to Measurements [PDF]

open access: yes, 2010
Noise continues to be an ongoing problem for existing aircraft in flight and is projected to be a concern for next generation designs. During landing, when the engines are operating at reduced power, the noise from the airframe, of which landing gear ...

T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Effects of Pitch Stabilization Buffer on the Dynamic Performance of Frame-Type Landing Gear

open access: yesAerospace
During the landing and taxiing process of aircraft, the frame-type landing gear (FTLG) usually generates large pitch vibrations under external excitation.

Established Numerical Techniques for the Structural Analysis of a Regional Aircraft Landing Gear

open access: yesAdvances in Materials Science and Engineering, 2018
Usually during the design of landing gear, simplified Finite Element (FE) models, based on one-dimensional finite elements (stick model), are used to investigate the in-service reaction forces involving each subcomponent.

Fault Analysis of Abnormal Opening of the Main Landing Gear Door of Civil Aircraft

open access: yesIOP Conference Series: Earth and Environment, 2020
The main landing gear door is an important component of the landing gear system. The system is in a state of failure and will not play the role of extending and retracting when the door extension/retraction fault.

Acoustic Measurements of a Large Civil Transport Main Landing Gear Model [PDF]

open access: yes22nd AIAA/CEAS Aeroacoustics Conference, 2016
Microphone phased array acoustic measurements of a 26 percent-scale, Boeing 777-200 main landing gear model with and without noise reduction fairings installed were obtained in the anechoic configuration of the Virginia Tech Stability Tunnel. Data were acquired at Mach numbers of 0.12, 0.15, and 0.17 with the latter speed used as the nominal test ...

Increased Fidelity in Prediction Methods For Landing Gear Noise [PDF]

open access: yes, 2006
An aeroacoustic prediction scheme has been developed for landing gear noise. The method is designed to handle the complex landing gear geometry of current and future aircraft. The gear is represented by a collection of subassemblies and simple components

Geophysical Investigations at the Artemision at Amarynthos of Euboea (Greece)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT A combination of resistivity mapping and three‐dimensional electrical resistivity tomography (ERT) was used to investigate the subsurface of the sanctuary of Artemis Amarysia in Amarynthos, Euboea (Greece), an area where archaeological remains from the Bronze Age to the post‐Byzantine period are preserved.
