Stroke is a common serious threat to human health and life. This article uses multivariate successive regression analysis methods discussed the relationship between incidence and average pressure, pressure difference, average temperature, temperature difference and the average humidity. Through statistical data we obtained the number of cases each year for each month and the incidence of personnel, as well as the number of cases with different gender, age and occupation to obtain a four-year comprehensive monthly temperature data. Finally, summary the results of the etiology of stroke and proposed early warning and intervention programs for high-risk groups.

The variation of different process parameters like bed height in static condition, diameter of the particles and density of the particles on the hydrodynamic behavior of a fluidized bed gasifier (FBG) in the cold model unit have been studied by using a Perspex material column of inside diameter 0.30 m and 0.15 m for the free board section and dense bed section respectively. A column of 1.95 m height was selected for the proposed experimental work. Experiments were conducted and attempts had also been made for the development of the correlations of Equivalence Ratio and Euler’s number by changing the different process parameters of the process on the basis of DA (dimensionless analysis). The mentioned numbers of the calculated values by DA as well as by matlab coding were compared with the experimental values. The percentage deviation such as standard deviation and mean deviation values for Equivalence ratio and Euler’s number were calculated to be 1.89, −0.049 and 2.64, 10.8 respectively which were within the permissible limits and showed a very good approximation. A chi-square test (ξ 2 ) for the said parameters (Equivalence Ratio and Euler’s number) gave 0.0002 and 18685.04 respectively which indicates a satisfactory correlation fit of the process. Hence the developed correlation from this study can be applied for industrial unit as well as for the pilot plant unit over a wide range of parameter with a suitable factor for scale-up.
