Studies showed that grids are significant to the accuracy of numerical simulation in hypersonic flows, but there is no definite method to determine the magnitudes of grid sizes yet.
Before the introduction of F-FDG-PET/CT as a non-invasive imaging tool for visualizing the early inflammation of atherosclerosis in the vessel, there was no definite method to detect subclinical atherosclerosis [ 42, 43].
But, historical geography can share both historical and geographical methodology because there is a definite method of enquiry for historical sources to be analyzed as well.
There is also no definite clinical method to determine in which patients with mild cognitive impairment progresses to AD with dementia [4] [5].
We use semi-definite programming method to study the properties of the optimization problem and derive useful results to be employed for robust network planning purposes.
For solving this problem, Qi [1] pointed out that (f(x)) defined by (1.4) is positive definite if and only if the real symmetric tensor (mathcal{A}) is positive definite, and provided an eigenvalue method to verify the positive definiteness of (mathcal{A}) when m is even (see Lemma 1.1).
The quality of the studies we found limits our ability to come to a definite conclusion as to the best method for implementing hypertension screening.
For solving this problem, Qi [1] pointed out that (f(x)) defined by (3) is positive definite if and only if the real symmetric tensor (mathcal{A}) is positive definite, and Qi provided an eigenvalue method to verify the positive definiteness of (mathcal{A}) when m is even (see Theorem 1).
It is an effective method to get a positive definite energy through one term, controlled by the other term in the principal part of the equations [7 19].
Since the potential well was introduced by Sattinger [7] in order to prove the global existence of solutions for nonlinear hyperbolic equations which do not necessarily have positive definite energy, it has become an important method to study the global existence and nonexistence of solutions for various nonlinear evolution equations.
