This offers great convenience in applying Newton's method to search for the parameters of stiffness factor inversely, as the Jacobian matrix can be obtained simply by solving sets of linear algebraic equation derived from the system equation. Examples of identifying stiffness factor distribution which ...
3. Hypertension and glucoregulation dysfunction are the precipitating factor of arteriosclerosis, atherosclorosis is the key pathogenesis links to cardiovascular events, because of the potential effects of assessing the degree of arterioscle rosis in cardiovascular and cerebrovascular diseases, as non-inva...
There is increasing evidences that suggest the pathological changes, caused by mechanical stimulation of spinal movement, are the primary factor of IDD. The mechanical stimuli of the intervertebral disc including compressive, tensile, and shear stresses [6,7,8]. The effects of compression stress on...
And the overall compliance factor comes only from the joints embedded by the virtual springs. This method was first proposed by Salisbury14, and then elaborated by Gosselin15. Pashkevich et al.16,17 considered the compliance of the link on this basis, and described the translational/rotational ...
In recent years, the biological role of changes in physical factors in carcinogenesis and progression has attracted increasing attention. Matrix stiffness, also known as ECM stress, is a critical physical factor of tumor microenvironment and remains alternating during carcinogenesis as a result of ECM ...
Using typical values for the moduli of these materials, Morris and Vansant compute a stiffness factor (case 1 in Table 9.3). Case 2 shows the effect of substituting a lower modulus mPE sealant for the ionomer. The bending stiffness is reduced by 67%. Case 3 shows that the thickness of ...
Google Share on Facebook stiffness constant [′stif·nəs ‚kän·stənt] (mechanics) Any one of the coefficients of the relations in the generalized Hooke's law used to express stress components as linear functions of the strain components. Also known as elastic constant. ...
found that there was no obvious damage on the diffusion layer with high stiffness under the ridge after F/T cycles and the ratio of channel to ridge was also an important factor to reduce the damage. Recently, changingpore diameter[158], ahydrophiliclayer [89] andPTFEloading [49] in the ...
Together, with the data on myofibroblast activation on non-crosslinked gels, this implicates substrate malleability as a potential factor in myofibroblast activation. Figure 6 SHG imaging of 3 mg/ml collagen gels polymerized at different temperatures. (A) SHG images of collagen gels polymerized at ...
This technique is denoted as the natural factor formulation. It is believed that the new approach leads to a better understanding of the relevant error analysis so powerfully initiated by Rosanoff et al.; see e.g. [20]. The natural factor formulation may also be shown to retain more ...
