“…In addition, the reforming process was considered external to the fuel cell stack. Another approach to MCFC dynamic modeling is found in [6] where the reforming process is considered internal to the stack but assumed to he at equilibrium. It is also assumed that mass accumulation in the stack is negligible.…”

A nonlinear mathematical model of an internal reforming molten carbonate fuel cell stack is developed for control system applications to fuel cell power plants. The model is based on principles of energy and mass component balances and thermochemical properties. Physical data for this model is obtained from a 2-MW system design that is a precursor to a demonstration fuel cell power plant running on natural gas at the City of Santa Clara, CA. The model can be used to provide realistic evaluations of the responses to varying load demqnds on the fuel cell stack and to define transient limitations and control requirements. Simulation results are presented for a transient response to a power plant trip at full load

“…As a result, they can make defensive and protective measures against danger rapidly. Ernest, GhezelAyagh, and Kush 23 believe that drivers with FI are better able to allocate attention resources to traffic information than those with FD, and have a better ability to monitor, extract, and organize information. The reaction in the eye movement index shows that drivers with FI have more fixations than those with FD.…”

Purpose Calligraphy is the most unique form of artistic expression in Chinese culture. However, most studies that used calligraphy as a research object only explored its artistic value from an artistic perspective. Thus, we know little about the information processing and influencing factors of calligraphic perception. Thus, we aimed to determine whether there are differences in attention distribution due to cognitive style in the process of calligraphic perception. Methods The calligraphy of Lan Ting Ji Xu , which is known as the first running script in the history of Chinese calligraphy, was selected as the experimental material. The study used eye movement experiments to explore the differences in cognitive styles of attention distribution when perceiving calligraphy, through the analysis of eye movement data of participants. Results The results showed that field-independent participants had more fixation duration, number of fixations, and saccade angle when they perceived calligraphic works than those who were field-dependent. In other words, field-independent individuals spend more attention resources in the perceptual process. In addition, through data analysis, it was found that fixation duration, number of fixations, and saccade angle in the middle position of calligraphy are larger than the data on both sides of the calligraphy. In other words, when individuals perceive calligraphy, the content in the middle position can attract more attention resources than those on both sides. Conclusion We found that individuals with different cognitive styles have differences in attention distribution in the process of perceiving calligraphy.
