The original MNF method mainly adopts the spatial feature of image to estimate ∑ N, such as minimum/maximum autocorrelation factor (MAF), causal simultaneous autoregressive, and quadratic surface [18].
Nevertheless, as stated in Table 3, this method was mainly adopted in only one research group, and rare other related reports with this method were found, which might be resulted from the expensive equipment, a relatively complex procedure and long treatment period.
While the first method is mainly adopted by psycholinguistic studies, the latter two are more often used in computer science studies.
Similarity metric methods in time sequence data mining mainly adopt the Euclidean distance [28], dynamic time warping distance [29, 30], irrelevant distance with complexity, etc. MSCA of this paper is implemented using the sliding window technology, which set a fixed window and slide on the time sequence.
In the aim of fulfilling requirements of an intensive use the choice has been made to mainly adopt semi-analytical approximated methods.
Clinicians mainly adopt antiviral treatment or immunomodulatory methods to improve liver function, and anti-fibrosis treatment to slow down the progression of the disease.
With regard to research methods, this study mainly adopted interviews of individuals and focus groups as well as supplementary semi-open public forums and questionnaire surveys.
For synthesis of the nano-sized CIS and CIGS powders, the solvothermal method has been mainly adopted, for it can easily control particle characteristics and produces much amount of powder [10].
The present studies mainly adopted qualitative methods to describe the impacts of political events on oil price fluctuation, and comparatively fewer studies have quantitatively estimated the impact of political instability on the oil prices.
The former mainly adopts the comprehensive index method and the multi-factor coupling method, while the latter mainly uses the EMR method, the microseismic method, and the drilling cutting method etc.
