the search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولThe Search for Gravitational Waves
The basic physics of g.w.'s emission, propagation and detection is outlined. The general features of candidate sources and detectors are discussed, showing how astrophysical emission events could be detected by devices not far from their Standard Quantum Limit. Two kinds of ground based detectors currently under active development, Km size interferometers and mK cold massive mechanical resonato...
متن کاملCross-correlation search for periodic gravitational waves
In this paper we study the use of cross correlations between multiple gravitational wave (GW) data streams for detecting long-lived periodic signals. Cross-correlation searches between data from multiple detectors have traditionally been used to search for stochastic GW signals, but recently they have also been used in directed searches for periodic GWs. Here we further adapt the cross-correlat...
متن کاملGravitational waves from eccentric compact binaries: Reduction in signal-to-noise ratio due to nonoptimal signal processing
Inspiraling compact binaries have been identified as one of the most promising sources of gravitational waves for interferometric detectors. Most of these binaries are expected to have circularized by the time their gravitational waves enter the instrument’s frequency band. However, the possibility that some of the binaries might still possess a significant eccentricity is not excluded. We imag...
متن کاملOn Investigating EMD parameters to Search for Gravitational Waves
The Hilbert-Huang transform (HHT) is a novel, adaptive approach to time series analysis. It does not impose a basis set on the data or otherwise make assumptions about the data form, and so the time–frequency decomposition is not limited by spreading due to uncertainty. Because of the high resolution of the time–frequency, we investigate the possibility of the application of the HHT to the sear...
