Theoretical coupled heat and moisture transfer model, internal pressure model and degradation constitutive model are applied in a discrete numerical method (Rigid Body Spring Model) to simulate the crack propagation as well as the strength degradation of concrete with non-uniform frost damage.
Extending these basic methods with rigid body constraints enables composite particles with complex shapes such as anisotropic nanoparticles, grains, molecules, and rigid proteins to be modeled.
The first is the automatic process in which conventional automatic deformation registration methods or rigid and linear transformation model can be used to coarsely register deformable images.
As an implementation of the aforementioned methods, a rigid endoscope is designed and fabricated with a FOV of 70° and an EPD of 0.3 mm.
The same process was applied to cumulate the dose in the LM positions as assessed by the DIR methods, the rigid registration and by the second observer (interobserver variability).
Table 2 shows the mean Euclidean distance between the positions of the landmark (LM) assessed by the first expert (reference) and the positions propagated by the 10 considered DIR methods, the rigid registration and the second expert, for each LM.
Axial motion artifacts are commonly corrected by using cross-correlation methods and rigid translations of each B-scan [ 24, 26] or through acquisition of orthogonal B-scans to aid alignment by providing a slow scan axis reference frame with no axial motion [ 27].
The appropriate support method is an integrated coupling method of rigid and flexible supports.
The method of rigid elements is used for this purpose.
Since the geometric matching alignment and scoring method uses rigid conformations, multiple conformers of each query molecule must be generated.
