Source Identification Techniques — A Critical EvaluationExperimental methods aimed at source identification continue to evolve. In the last decade, computers, programmable or dedicated, have provided the experimenter with unprecedented data processing capabilities. Highlights of several techniques are presented along with comments regarding limitations and characteristic results.

The Political Economy of the USSRource < e.g., the shadow of an object interposed in a beam of light >; and is manifest by a non-zero level of excitation in such regions. This, and the kindred phenomena of reflection and refraction, is explicable by means of superposed wave functions that are separately linked with the primary or g

The Surplus and Class StructureThe analysis is based on Rapid Distortion Theory. High frequency gusts, whose wavelengths are short compared to the airfoil chord, are considered. The noise generation is shown to be concentrated near the airfoil leading edge. The level of the generated noise is increased by airfoil mean loading, wi

Adaptive Time-Delayed Feedback Controlfield is obtained as close as 0.2 mm away from the wall and we are able to resolve the Stokes layer of the incoming flow. The perturbation of the shear-layer is discussed and the vorticity in the downstream region is evaluated from the velocity field. Additionally the displacement of the separation

Synchronization in Complex Networksduces unsteady vortex shedding at the edge and the vorticity is convected away into regions where it is unable to interact significantly with the sound, and where its energy is ultimately dissipated as heat. The U.K. Science and Engineering Research Council is supporting an experimental study at Sou

Cluster and Group Synchrony: The Theorye concept does not necessarily violate the Laws of Physics, the topic has suddenly become accepted and respectable. Indeed, the possibility now arises of its being regarded as a universal panacea for all noise control problems, with equally dangerous effects on its rational development for the long

Eckhard Frischbier,Holger Pfeifferperformance introduced by some of the features that are likely to be inherent in real systems. These include the limitations on the control system caused by finite computational power and the need for the controller to be causal. We also consider the effect of noise corruption of the sensor signal a
