The Rhapsody Semantics of Statecharts

We describe the semantics of statecharts as implemented in the current version of the Rhapsody tool. In its original 1996 version this was among the first executable semantics for object-oriented statecharts, and many of its fundamentals have been adopted in the Unified Modeling Language (UML). Due to the special challenges of object-oriented behavior, the semantics of statecharts in Rhapsody d...

Turbulence in Geophysics

Fluid in Geophysics including atmosphere and ocean, compared with the normal fluid in Hydrodynamics, its properties, such as density, pressure, temperature and velocity, all change along with altitude. That is to say, fluid in Geophysics is stratified. Therefore, the characteristics of its turbulence at different stratifications will not be the same, either. Some special characteristics, as wel...

Preface Fractals in geophysics

Geophysical phenomena of interest to geoscientists include both atmospheric and terrestrial related processes, which can be either static or dynamic. Characterization of such phenomena requires advanced models which often include scale invariance concepts of fractal or multi-fractal type. Recently, there has been much interdisciplinary interest in the application of geophysical processes. The a...

Reservoir geophysics

The concept of petroleum reservoir geophysics is relatively new. In the past, the role of geophysics was largely confined to exploration and, to a lesser degree, the development of discoveries. As cost-efficiency has taken over as a driving force in the economics of the oil and gas industry and as major assets near abandonment, geophysics has increasingly been recognized as a tool for improving...
