I develop a phenomenological approach to the description of the noise levels that the space-time foam of quantum gravity could induce in modern gravity-wave detectors. Various possibilities are considered, including white noise and random-walk noise. In particular, I find that the sensitivity level expected for the planned LIGO and VIRGO interferometers and for the next upgrade of the NAUTILUS ...

Europhysics Letters PREPRINT Capillary-gravity waves: a " fixed-depth " analysis. PACS. 68.10.-m – Fluid surfaces and fluid-fluid interfaces. PACS. 47.17.+e – Mechanical properties of fluids. Abstract. – We study the onset of the wave-resistance due to the generation of capillary-gravity waves by a partially immersed moving object in the case where the object is hold at a fixed immersion depth....

The gravity of Earth is responsible for the formation of water waves and usually difficult to change. Although negative effective gravity was recently predicted theoretically in water waves, it has not yet been observed in experiments and remains a mathematical curiosity which is difficult to understand. Here we experimentally demonstrate that close to the resonant frequency of purposely-design...

An overview of some tools and techniques being developed for data conditioning (regression of instrumental and environmental artifacts from the data channel), detector design evaluation (modeling the science “reach” of alternative detector designs and configurations), noise simulations for mock data challenges and analysis system validation, and analyses for the detection of gravitational radia...

This study synthesized knowledge regarding waveand current-supported sediment gravity flows and their importance to shelf deposition and morphology. Data and publications from STRATAFORM, EuroSTRATAFORM and several river-nourished shelves in Asia and the Western Pacific were reviewed and models for wave-supported fluid muds and resulting gravity flows were applied. Field and modeling evidence s...

Perturbations to the orographic gravity wave parameterization scheme in an idealized general circulation model reveal a remarkable degree of compensation between the parameterized and the resolved wave driving: when the orographic gravity wave driving is changed, the resolved wave driving tends to change in the opposite direction, so there is little impact on the Brewer–Dobson circulation. Buil...

Simultaneous observations of gravity waves using an Na wind/temperature lidar and a multi-wavelength all-sky nightglow imager were obtained, for the first time, during the ALOHA-93 campaign. A novel investigation of intrinsic wave parameters has been made by combining measurements of the horizontal wave components imaged in four nightglow emissions (height range ~80-100 kin) with Na lidar sound...

In the field of computer graphics, we have several research results to display the ocean waves on the screen, while we still not have a complete solution yet. Though ocean waves are constructed from a variety of sources, the dominant one is the surface gravity wave, which is generated by the gravity and the wind. In this paper, we present a real-time surface gravity wave simulation method, deri...

The effects of wave and zonal mean ozone heating on the evolution of the quasi-biennial oscillation (QBO) are examined using a two-dimensional mechanistic model of the equatorial stratosphere. The model atmosphere is governed by coupled equations for the zonal mean and (linear) wave fields of ozone, temperature, and wind, and is driven by specifying the amplitudes of a Kelvin wave and a Rossby–...
