改进的计算网格域内实体信任模型设计

传统基于信任域的网格信任模型以自治域内的实体数目作为信任值计算复杂度的唯一参数,安全性较低。在现有计算网格信任模型基础上,提出一种改进的自治域内实体信任模型,将时间衰减和惩罚因子引入到模型中,建立GSP对用户的直接信任度和推荐信任度计算模型,通过仿真实验验证其具有更高的抗Whitewashing攻击能力。     

GSP气化技术煤粉密相输送系统稳定性研究

为实现大规模工业化GSP气化技术煤粉密相输送系统的稳定输送,研究了煤粉物性、输送工艺、操作参数对输送特性的影响。结果表明:当煤粉湿含量由6.9%降到4.2%时,锁斗下料顺畅,减压系统偶尔出现堵塞。采用压差控制输送煤粉时,煤粉质量流量波动大于20 t/h,而采用流量调节控制煤粉输送时,煤粉质量流量波动小于5 t/h,因此,采用流量调节控制时,煤粉输送稳定性大幅提高。当操作参数进料器流化气量由220～180 m3/h调整为90～140 m3/h时,煤粉输送管线注射器1气体的流量由7 m3/h调整为3 m3/h,投煤后关闭注射器2,可使固气比由280 kg/m3增加到400 kg/m3,质量流量由42 t/h增加到72 t/h,进一步提高了煤粉密相输送系统的稳定性。

Glossopharyngeal nerve transection impairs unconditioned avoidance of diverse bitter stimuli in rats.

There is growing evidence of heterogeneity among responses to bitter stimuli at the peripheral, central and behavioral levels. For instance, the glossopharyngeal (GL) nerve and neurons receiving its projections are more responsive to bitter stimuli than the chorda tympani (CT) nerve, and this is particularly true for some bitter stimuli like PROP & cycloheximide that stimulate the GL to a far greater extent. Given this information, we hypothesized that cutting the GL would have a greater effect on behavioral avoidance of cycloheximide and PROP than quinine and denatonium, which also stimulate the CT, albeit to a lesser degree than salts and acids. Forty male SD rats were divided into four surgery groups: bilateral GL transection (GLX), chorda tympani transection (CTX), SHAM surgery, and combined transection (CTX + GLX). Postsurgical avoidance functions were generated for the four bitter stimuli using a brief-access test. GLX significantly compromised avoidance compared to both CTX and SHAM groups for all stimuli (p     

Dexterous workspace optimization of an asymmetric six-degree of freedom Stewart–Gough platform type manipulator

In this paper, an asymmetric Generalized Stewart–Gough Platform (GSP) type parallel manipulator is designed by considering the type synthesis approach. The asymmetric six-Degree Of Freedom (DOF) manipulator optimized in this paper is selected among the GSPs classified under the name of 6D. The dexterous workspace optimization of Asymmetric parallel Manipulator with tEn Different Linear Actuator Lengths (AMEDLAL) subject to kinematics and geometric constraints is performed by using the Particle Swarm Optimization (PSO). The condition number and Minimum Singular Value (MSV) of homogenized Jacobian matrix are employed to obtain the dexterous workspace of AMEDLAL. Finally, the six-DOF AMEDLAL is also compared with the optimized Traditional Stewart–Gough Platform Manipulator (TSPM) considering the volume of the dexterous workspace in order to demonstrate its kinematic performance. Comparisons show that the manipulator proposed in this study illustrates better kinematic performance than TSPM.
