Systematic design techniques, such as the rectification body, column profile map, and temperature collocation methods, require exact knowledge of all pinch points in a particular system, because these stationary points delineate the possible composition trajectories realizable in separation columns. This paper demonstrates novel methods for rigorously determining all pinch points for the constant relative volatility, ideal and non-ideal systems. Constant relative volatility and ideal solution systems are transformed into one-dimensional polynomial and nonlinear functions, regardless of the number of the components. A deflation method is proposed to locate all zeros in ideal and non-ideal zeotropic problems. For more challenging non-ideal problems, a novel hybrid sequential niche algorithm is used to solve hard azeotropic problems successfully. Finally, the design implications of these pinch point locations are investigated to show how new separation configurations can be devised. Methodically the paper points out the use of rigorous pinch point computations in conjunction with continuous composition profiles for robust distillation design.展开更多

Due to the fact that most magazines are created with an intention of convincing readers of various ideologies, most linguists would consider the use of loanwords to give a comprehensive presentation of ideas. Incorporating English loanwords is not only a requisite tool for integrating and addressing the cultural differences between various communities across the globe, but also acts as a bridge that fills the conceptual gaps that exist in various languages. This is no longer the job of a linguist, because there are many other ways through which the people of a particular country can adopt a loanword （e.g., social media）. Also, it enriches the recipient language and puts its citizens up to date with the latest developments and inventions.展开更多

Therefore, it is necessary to culture the appearance and development of Internet Movie, is bound to the mode of expression, the people＇s cultural psychology and social individual to collective identity have significant influence.展开更多

Aware of the social ties, the cooperative network contains two layers of property: social and physical. In order to observe how the social awareness benefit the cooperation performance, we first formulate the social ties between MTs into parameters that can describe the cooperative behaviors by taking the mobility feature into account, defined as the conviction-approval-suspicion(CAS) model. Limited by the processing capability, partner selection is of great practical significance. To this end, the social-aware partner selection strategy is analyzed, and a significant superiority is observed compared to social-unaware selection. By analyzing the cooperative throughput, an explicit relationship between the degrees-of-freedom gain and the social-physical property is finally derived. Simulation results validate the theoretical analysis.展开更多

The spread of the online word of mouth as a platform for the Interact highlights its great influence and importance. Especially in the online shopping, these reflect the user＇s point of view and attitude of the online comment has been an unprecedented attention. Online reviews have become an important medium for consumers to understand their products before they buy goods, making them an important channel for potential consumers to understand the quality of goods and services. There are many studies on online reviews, but the research on the brand awareness of cruise ship companies is almost negligible. This paper provides a reference for the construction of cruise ship brand awareness system, and combines Nvivo software to analyze the online commentary system, and provides a reference for further research on cruise brand, and prospects for future research.展开更多
