Gravitational Wave Scintillation by a Stellar Cluster

General Relativity predicts the existence of gravitational waves that propagate in the vacuum with the speed of light. Analogously to electromagnetism, it is expected that gravitational waves might also be scattered by intervening particles 1,2,3 and micro-lensed by compact objects along the line of sight 4,5,6. Moreover, gravitational waves will be diffracted as they pass through a distributio...

Stellar scintillation technique for the measurement of tilt anisoplanatism

The significance of tilt anisoplanatism is established, and a measurement theory, based on aperture-averaging intensity scintillation, is developed. The theory is a direct extention of the technique currently used to determine the isoplanatic angle as defined by Fried [J. Opt. Soc. am. 72, 52 (1982)]. By using this theory, a physically realizable binary aperture-weighting function is derived fo...

Multiagent Meta-Level Control for Predicting Meteorological Phenomena

It is crucial for social systems to adapt to the dynamics of open environments. This adaptation process becomes especially challenging in the context of multiagent systems. In this paper, we argue that multiagent meta-level control is an effective way to determine when this adaptation process should be done and how much effort should be invested in adaptation as opposed to continuing with the c...

Meteorological Phenomena Forecast Using Data Mining Prediction Methods

The occurrence of various meteorological phenomena, such as fog or low cloud cover, has significant impact on many human activities as air or ship transport operations. The management of air traffic at the airports was the main reason to design effective mechanisms for timely prediction of these phenomena. In both these cases meteorologists already use some physical models based on differential...
