Towards a classification of wave catastrophes
نویسندگان
چکیده
Wave catastrophes are characterized by logarithmic phase singularities. Examples are light at the horizon of a black hole, sound in transsonic fluids, waves in accelerated frames, light in singular dielectrics and slow light close to a zero of the group velocity. We show that the wave amplitude grows with a half-integer power for monodirectional and symmetric wave catastrophes.

AN APPROACH TOWARDS WAVE CLIMATE STUDY IN THE PERSIAN GULF AND THE GULF OF OMAN: SIMULATION AND VALIDATION
This article describes the 11-year wave simulation (1992-2002) in the Persian Gulf and the Gulf of Oman using the input data derived from European Center for Medium-Range Weather Forecasts (ECMWF). The ECMWF 10 meter wind field and spectral wave boundary condition at 18 ْN degree are input into one of the latest versions of numerical wave models (3rd generation) after a few local modifications. ...

Estuaries and bays are areas with a wide range of hydrodynamic and morphological phenomena. The existence of this diversity in environmental processes will lead to complex and sometimes unknown interactions in their structure. Understanding the behavior and environmental conditions of these beaches will improve the attitude of coastal users for better management of these areas. Many classificat...
متن کاملPrediction model of limestone rock mass quality, using seismic wave velocity (Case study: Sarvak formation in Bakhtiari dam site)
The purpose of this study was to develop a model for the estimation of rock mass classification of Sarvak limestone in the Bakhtiari dam site, south-west (SW) Iran. Q system had been used as the starting point for the rock mass classification. This method was modified for sedimentary rock mass which is known as Qsrm. Because Qsrm considers a wide range of rock mass propert...

Recent catastrophes, and predictions of an increasing potential for more, have stimulated thinking about the best policy responses to these threats. This article explores how security concepts influence catastrophe governance. The article considers how globalization affects thinking about catastrophes and describes ways in which catastrophes have been conceptualized as governance challenges, su...
متن کاملA COMPREHENSIVE APPROACH TOWARDS THE CLASSIFICATION OF CRACKS IN UN-REINFORCED MASONRY BUILDINGS
Cracks emerge due to various forces or stresses. After discerning the cracks preferably by non-destructive techniques, there is a need to find the reason for their appearance. With very exact analysis of the shape, form and dimension of the cracks and their location on the structural elements, we can deduce the reason for their formation. This makes, proposing a suitable solution for preventin...
