Gravitational lenses as long-baseline gravitational-wave detectors [PDF]

open access: yesPhysical Review Letters, 1989
Gravitational waves produce a time delay between the different images of a gravitational lens. The measurements of the time delay in the gravitational lens 0957{plus minus}561 put new limits on the amplitude of low-frequency gravitational waves {ital h}{lt}2{times}10{sup {minus}5}({nu}/(3{times}10{sup {minus}18} Hz)) in the frequency range 3{times}10 ...

Low-frequency terrestrial gravitational-wave detectors [PDF]

open access: yesPhysical Review D, 2013
Direct detection of gravitational radiation in the audio band is being pursued with a network of kilometer-scale interferometers (LIGO, Virgo, KAGRA). Several space missions (LISA, DECIGO, BBO) have been proposed to search for sub-Hz radiation from massive astrophysical sources.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

open access: yesAdvanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Gravitational wave detection based on gravitomagnetic effects

open access: yesPhysics Letters B
In this paper, we explore the feasibility of detecting gravitomagnetic effects generated by gravitational waves, by monitoring the relative orientation of the angular momentum vectors of test particles.

Gravitational Wave & Relativity Impact Electronic Communication & Engineering

open access: yesMATEC Web of Conferences, 2017
About a few months ago (Feb 11, 2016), the LIGO (Laser Interferometer Gravitational-Wave Observatory) scientist team researchers made an announcement that they had confirmed the gravitational wave already detected on Sept 14, 2015 (by LIGO’s twin ...

The Advanced LIGO timing system [PDF]

open access: yes, 2010
Gravitational wave detection using a network of detectors relies upon the precise time stamping of gravitational wave signals. The relative arrival times between detectors are crucial, e.g.

A REVIEW OF GRAVITATIONAL WAVE DETECTORS [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 1997
▪ Abstract  This review is devoted to presenting the status of the experimental search of gravitational radiation. After a short history of the development of detectors, we present the state of the art for both resonant antennas and interferometers. The final section is devoted to possible future developments of both techniques.

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

open access: yesAdvanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Gravitational-wave signatures of chiral-symmetric technicolor

open access: yesPhysics Letters B, 2022
A chiral-symmetric technicolor model successfully reconciles the tension between electroweak precision tests and traditional technicolor models. Focusing on its simplest realization preserving the conventional Higgs mechanism, we study its primordial ...
