The study nucleoti de substitution is very important both to our understanding of gene evolution and to reliable estimation of phylogenetic relationships. In this paper nucleotide substitution is assumed to be random and the Markov model is applied to the study of the evolution of genes. Then a non-...

The increased use of information technologies has led to more research on information technology/information system (IT/IS) adoption and decision-making behavior in small businesses to improve information utilization. This paper presents an extensive review of the literature on IT/IS adoption to ide...

To overcome the too fine-grained granularity problem of multivariate grey incidence analysis and to explore the comprehensive incidence analysis model, three multivariate grey incidences degree models based on principal component analysis (PCA) are proposed. Firstly, the PCA method is introduced to ...

Optimal distribution feeder reconfiguration (DFR) is a valuable and costless approach to increase the load balance, reduce the amount of power losses, and improve the voltage of the buses. In this way, this paper aims to investigate the optimal DFR strategy as a proper tool to improve the reliabilit...

Multi-level converters have been used extensively in modern industry which calls for energy conversion with high-power and high-or medium-voltage. Because of its modularity and scalability, the multi-level converter with modular structure can be extended to different voltage levels and has a variety...
