This paper presents some of the results of the simulation in the radiation section of an industrial boiler using an advanced mathematical model. Calculations are described for the flow, heat transfer, and chemical reaction processes occurring within a gas-fired cylindrical furnace. The calculation procedure is a two dimensional one in which the main hydrodynamic variables are the velocity and s...

Direct volume-rendering has proven to be an effective and flexible visualization method for 3D scalar fields. Transfer functions are fundamental to direct volume-rendering because their role is essentially to make the data visible: by assigning optical properties like color and opacity to the voxel data, the volume can be rendered with traditional computer graphics methods. Good transfer functi...

of the traditional smooth inversion this information is provided as [2J The two-dimensional (2-D) magnetotelluric inverse problem an assumption that the solution, the geoelectrical model in the MT has been addressed by several authors. The most well-known case, should be represented by smooth functions. At the same time, approaches are the search for a smooth model [de Groot-Hedlin in some geol...

The Ries Crater was formed about 12 million years ago, 120 km northwest of Munich in the district of Donau-Ries. The crater is estimated to have had a diameter of approximately 24 kilometers. In this report we discuss the preand post-impact structure of the crater site, and in particular try to investigate whether or not the Ries Crater shows evidence of structural uplift, a characteristic of m...

In this paper we develop a fast 3-D electromagnetic (EM) migration method for marine geophysical exploration. The developed migration algorithm is based on downward extrapolation of the observed EM field using a special form of finite-difference equation for the migration field. It allows us to migrate within the sea-bottom formations the EM signals observed by the sea-bottom receivers. The mig...
