Robustness of the model is estimated by initializing different level sets and the robustness against sensitiveness of intensity inhomogeneity by using different percentage of bias corrupted MR image has been used.
Although the linking of the silane molecule onto the metal surface is fast, due to the rapid formation of hydrogen bonds between SiOH with metal hydroxyl groups at the metal surface, (20) low immersion time could induce inhomogeneity on the coating coverage.
In our approach the inhomogeneity of the system is expressed via the viscosity [mu] which is treated as a function of space and time (Anand and Rajagopal, 2005; Massoudi and Vaidya, 2011).
The presence of deformations on the surface of the material due to precipitate formation caused by the inhomogeneity of the material matrix, causes localized stress points throughout the material.
The values obtained at a distance which is defined and a constant speed of movement of the tractor allows the evaluation of higher quality data, because one can reduce the impact of soil inhomogeneity due to large amounts of measured values (Jejcic & Poje, 1995).
There are several inherent difficulties in modeling and sizing ground heat exchangers: diverse length and time scales, unknown inhomogeneity of the ground, and high capital cost.
Although stress MDCT examinations are impractical with 4-detector through 64-detector scanners because of temporal inhomogeneity, recent advances in MDCT technology have led to the development of wide-area detector scanners with up to 320 detectors in the z-axis, permitting imaging of the entire heart in one gantry rotation (Figure 5).
