Biot’s parameter is included in the formula for calculating effective stresses and should be taken into account when assessing stress-strain state of a water-saturated rock mass. A method tensor based on asymptotic averaging equilibrium equation fluid-saturated porous medium proposed. Calculations elastic properties coefficient were carried out various types rocks - limestone, dolomite, hyalocl...

Abstract Mathematical methods take an important part in reconstruction technologies of radiographic image. Back projection, iterative, and analytical (Two-dimensional Fourier, Filtered Projection) are the most procedures for image reconstruction. Whenever there exists numerous projections, have a great performance speed accuracy due to these advantages they comprehensively used X-ray imaging. O...

The accurate reconstruction of the in vivo dose is a critical step radiation therapy. X-ray-induced acoustic imaging promising technology for reconstruction, as it enables nonradiative and noninvasive monitoring dose. However, current X-ray methods suffer from several limitations, including high signal-to-noise ratio, poor quality massive loss structural information. To address these we propose...

Lung lesion identification is an important aspect of early lung cancer diagnosis. Early may assist physicians in treating patients. This paper uses computed tomography scan images to present a geometrical feature. From the previous studies, segmentation particularly challenging because differences pulmonary inflation with elastic chest wall can result significant variability volumes and margins...

Currently, the treatment of peripheral arterial obstructive disease (PAOD) based on plaque morphology is still debated;1Conte M.S. Bradbury A.W. Kolh P. White J.V. Dick F.

Over the past decade a growing number of high resolution, three-dimensional, X-ray computed tomography images of multiphase porous media systems have become available, as have the number of algorithms to analyze both the pore space and the fluid partitioning imaged within the voids. Here we consider the measurement of fluid-fluid and fluid-solid surfaces at residual fluid conditions in a Berea ...
