The traditional Hessian-related vessel filters often suffer from the problem of handling non-cylindrical objects. To remedy the shortcoming, we present a shape-tuned strain energy density function to measure vessel likelihood in 3D images. Based on the tensor invariants and stress-strain principle in mechanics, a new shape discriminating and vessel strength measure function is formulated. The s...

A biphasic, anisotropic elastic model of the aortict wall is developed and compared to literature values of experimental measurements of vessel wall radii, thickness, and hvdraulic conductivity as a function of intraluminal pressure. The model gives good predictions using a constant wall modulus for pressures less than 60 mmHg, but requires a strain-dependent modulus for pressures greater than ...

Methane is one of the most common gaseous fuels that also exist in nature as main part natural gas, flammable biogas or reaction products from biomass pyrolysis. In this respect, and installations are always subjected to explosion hazards due methane. Simple methods for evaluating great importance, at least preliminary stage. The paper describes such a method based on an elementary analysis cub...

Analysis of the work, which considered mathematical modeling melting process in various industries, currently does not pay attention to processes heating and hydrocarbon mixtures, such as vaseline, paraffin, fats, lanolin others. The issue optimization processes, calculations necessary parameters (speed depth thermal front penetration, etc.) equipment, avoidance repetition for each mixture expe...

Improvement of nondestructive inspection techniques has made more frequent the detection zones containing closely spaced non-metallic inclusions in pressure vessels low carbon steel. In present study, an in-service cylindrical horizontal vessel were detected by Scan-C ultrasonic and considered as laminations to be assessed Part 13 API 579-1/ASME FFS-1 2016 standard. The outcoming results reject...

In this study, we investigate the trajectory of magnetic nanoparticle flowing through a microvessel in presence cylindrical magnet. By using equation motion particle and fluidic forces, is calculated. Our numerical results show that probability trapping particles straight function intensity field, radius, magnetization, diameter vessel. effect magnet saturation magnetization vessel radius on Th...
