TAM theory is applied in this research and the research is to study the factors that will lead to acceptance and participation of e-Learning system for the development of IT Literacy for Thai students. It uses the technique of SEM and the result from collecting data of 420 students found that Goodness of fit indicators which also included a chi-square value of 267.84, CMIN/ DF = 1.87, SRMR = .05, GFI = .93, TLI = .97, CFI = .97, RMSEA = .05 and HOELTER = 269. Additionally, there are 2 factors which include; Perceived usefulness (PU) and Perceived ease of use (PEOU). Both factors have positive (+) direct influence on behavioral intention (BI). Moreover, there are 3 factors including Information quality (IQ), Functionality (FL) and Accessibility (A) which have a positive (+) indirect influence on behavioral intention (BI). The BI have been determined based on (PU) perceived usefulness along with perceived ease of use (PEOU). This lead to result in a R 2 = .80. Therefore, the variables described earlier lead to the explanation that 80% of variance on behavioral intention (BI).
We would like to propose a Cooley-Tukey modified algorithm in fast Fourier transform(FFT). Of course, this is a kind of Cooley-Tukey twiddle factor algorithm and we focused on the choice of integers. The proposed algorithm is better than existing ones in speeding up the calculation of the FFT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
