This paper addresses the characteristics of power enterprise scientific research projects, categorizing them into theoretical research, applied research, product research, and others. Based on the project advancement process, evaluation indicator systems are constructed from three dimensions: project initiation level, implementation level, and implementation effectiveness. The G1-DEMATEL method is employed to weight the indicators, with weights converted to a percentage scale for ease of use in evaluations. This evaluation system provides a comprehensive and objective assessment of power enterprise scientific research projects, offering strong support for research decisions and enhancing management and innovation capabilities.展开更多

By using this method abundant travelling wave so- lutions with arbitrary parameters of the Zakharov equations are successfully obtained. When the parameters are replaced by special values, the well-known solitary wave solutions of the equations are rediscovered from the travelling waves.展开更多

The exact solutions are derived, in terms of hyperbolic, trigonometric and rational functions, involving various parameters. When the parameters are tuned to special values, both solitary, and periodic wave models are distinguished. State of the art symbolic algebra graphical representations and dynamical interpretations of the obtained solutions physics are provided and discussed. This in turn ends up revealing salient solutions features and demonstrating the used method efficiency.展开更多
