growth and showed that: GDP is the reason that affects domestic tourism income, but domestic tourism income has little effect on GDP [ 7 ]. As a quantitative literature research method, meta-analysis is quite different from the traditional literature review. Meta-analysis is a literature review of higher-level logical forms. It uses the original research results as a unit, and the design is more rigorous. It emphasizes a comprehensive literature search on relevant research, and has a clear criterion for document inclusion and exclusion, systematically considering the

Using number of shared files owned by the user as the main parameter, the model characterizes evolutionary process

-trivial conservation laws. After Ibragimov’s results several papers appeared concerned with self-adjointness and its applications to PDEs [ 24 , 25 ]. In this work, we derive conservation laws by using the direct method of the multipliers [ 4 ]. Furthermore, due to the fact that equation (1) admits groups of space and time traslations, we look for travelling wave solutions of the density dependent reaction-diffusion equation (1) with physical interest. In order to do that we apply the well known G ′ G $\begin{array}{} \displaystyle \frac{G'}{G} \end{array}$ -expansion

Another suggestion of an alternative method of interpreting the results of TS tests is the back analysis of the τ ( γ ) relation in the first quarter of the hysteresis loop. This method finds particular application in the process of calibration of constitutive laws implemented in Finite Element Method based calculation applications. The authors have their own application that works with the MatLab system and enables automated search for explicit and discrete G ( γ

. In this paper we describe the theory of isospectral network reductions. This is a method that allows us the ability to reduce a network while preserving the large majority of the network’s spectral structure , i.e. the eigenvalues and eigenvectors associated with the network. This method also preserves the structural features of the network in that the paths and cycles of the original network are compressed into smaller paths and cycles, respectively, to create the reduced network. The reason we choose to maintain the spectral structure of a network is that a

It can produce these functions from either uniform or arbitrarily spaced data points. The viewing times are obtained by extracting the real roots of localized quantic.

perfect autocorrelation (1) allows for its decorrelation in noisy environments. This fact has been extensively employed in pulse-compression radar, and in frame synchronization, channel equalization and estimation, and cell search in wireless communication systems [ 4 , 5 , 6 ]. Finally, property (2) permits the design of coded waveforms with uniform spectrum, with application as direct-sequence spread-spectrum codes or acoustic diffusers [ 7 ]. In these applications, the generation of coded waveforms typically uses a two-step method, where the sequence is first

. Statistics is already considered to be a basic ingredient of medical education and routinely used in research, specifically in clinical studies. This is so even when many physicians have a limited understanding of statistics and risk analysis [ 2 ]. However, the potential of other mathematical tools such as differential equations, advanced numerical methods, optimization, etc, have not been broadly incorporated into medical research on clinical care. This is so in spite of the fact that these methods are part of the standard toolbox of the applied mathematician that have
