Objective: To reveal the provincial clustering of malaria in Iran between 2005 and 2014 based on the epidemiologic factors and the climatic indicators affecting the disease. Methods: This was a descriptive-analytical study using malaria and meteorological data from the Malaria Elimination Programme of the Ministry of Health and Medical Education and National Meteorological Organization. After standardization, the aggregate data was used to produce 10-year means for each province. The data analysis included grouping the provinces with respect to factors using hierarchical clustering method and Kruskal-Wallis test to examine the difference between clusters using sPss ver.23. Results: The hierarchical clustering stratified the provinces' in 5 clusters. Kruskal-Wallis H test revealed a significant difference in the incidence rate per 100000 population (P=0.001), male gender (P=0.001), Iranian nationality (P=0.001), Afghan nationality (P=0.003), Pakistani nationality (P=0.001), urban residence (P=0.006), rural residence (P=0.004), autochthonous cases (P=0.007), average minimum temperature (P=0.001), average maximum temperature (P=0.007), average relative humidity (P=0.011), average pressure level (P=0.038), prevailing wind direction (P=0.023), average wind speed (P=0.031) and average precipitation sum (P=0.002) among the clusters. Conclusions: The results of this study and stratification of the provinces could help health policy makers to better manage malaria by allocating resources accordingly.

超级高铁运输技术(HTT)是一种新型运输方式.它的工作原理是将一种称为吊舱的超高速车辆移动到低气压管中.本文研究了考虑空气动力载荷的新型混合悬浮吊舱的稳定性分析.拟议的吊舱包含两个悬浮装置:磁悬浮(EMs)和气垫.在这方面,气垫有助于系统克服整体重量.EMs悬架有两个比例微分(PD)控制器,可在存在空气动力载荷的情况下稳定吊舱的运动:一个控制垂直位移,另一个控制横向运动.本文建立了吊舱的五自由度动力学模型,包括吊舱的垂直和横向位移以及吊舱的俯仰、滚转和偏航力矩.介绍了气垫、磁悬浮和空气动力载荷的动态模型.求解相关动力学方程后,研究了控制器参数和气动升力和阻力载荷对吊舱稳定性的影响.此外,还分析了控制器系数和其他一些吊舱设计参数(包括气垫刚度、总质量和管内气压)对临界速度的影响.

This research provides experimental evidence for localized shear, billet cracking, and segmentation during the processing of various copper alloys. The results demonstrate that although many parameters affect the shear localization, there is a direct relation between segmentation and alloy strength （hardness） that is related to the alloying elements and constitutive phases. For instance, alpha brass is successfully processed by ECAP at room temperature, but alpha/beta brasses fail even at a temperature of 350 °C. Finite element simulation of cracking and segmentation was performed using DEFORMTM to investigate the influence of different parameters on segmentation. The results confirm that friction and processing speed have narrow effects on attaining a perfect billet. However, employing back pressure could be reliably used to diminish shear localization, billet cracking, segmentation, and damage. Moreover, diminishing the flow localization using back pressure leads to uniform material flow and the billet homogeneity increases by 36.1%, when back pressure increases from 0 to 600 MPa.
