应用现代管理思想确立现代远程教育质量管理原则

笔者首先应用知识管理论的思想,把远程教育的研究视角从单纯的教育信息传播和学习资源与学习过程的管理提升到知识管理层面作了深入的探讨,以图拓展现代远程教育领域的研究视野;其次应用全面质量管理的思想,建立现代远程教育服务质量管理的新观念;最后应用ISO（国际标准化组织）9000的思想和过程方法模式,确立现代远程教育质量管理的基本原则,包括以学习者的需求为中心、领导作用重新定位、全员参与、基于知识的管理、过程方法、自我评价、持续改进与组织学习、互惠的伙拌关系等8条原则。

Filtration of micro-particles within multi-fiber arrays by adhesive DEM-CFD simulation

A 3D multi-time scale discrete element method-computational fluid dynamic (DEM-CFD) coupling approach was applied to investigate the filtration of micron-sized particles by different types of fiber arrays. Both the pressure drop and the filtration efficiency were examined to indicate the filtration performance of the fiber arrays. Fibers that were uniformly arrayed in a parallel or staggered manner were compared. Results showed that the staggered array showed a better performance than the parallel array in terms of both pressure drop and filtration efficiency. Further, we compared the performance of different staggered arrays, i.e. a regular case, one densified in the front layers and another densified in the back layers. The front densified array was found to enter the clogging and cake filtration stage in the shortest time, leading to the highest filtration efficiency, but the highest pressure drop. The back densified array still achieved a much higher filtration efficiency, despite a much lower pressure drop comparable to that of the regular array. The results suggest that the two kinds of densified arrays may be suited for different purposes, e.g. baghouse filters or breathing masks.     

A novel multi-objective optimization method for the pressurized reservoir in hydraulic robotics

The pressurized reservoir is a closed hydraulic tank which plays a significant role in enhancing the capabilities of hydraulic driven robotics. The spring pressurized reservoir adopted in this paper requires comprehensive performance, such as weight, size, fluid volume, and pressure, which is hard to balance. A novel interactive multi-objective optimization approach, the feasible space tightening method, is proposed, which is efficient in solving complicated engineering design problems where multiple objectives are determined by multiple design variables. This method provides sufficient information to the designer by visualizing the performance trends within the feasible space as well as its relationship with the design variables. A step towards the final solution could be made by raising the threshold on performance indicators interactively, so that the feasible space is reduced and the remaining solutions are more preferred by the designer. With the help of this new method, the preferred solution of a spring pressurized reservoir is found. Practicability and efficiency are demonstrated in the optimal design process, where the solution is determined within four rounds of interaction between the designer and the optimization program. Tests on the designed prototype show good results.

面点实践教学中工艺标准化探析

在当前面点教学中,大部分教师仍处于凭经验教学阶段,各类教学品种无定量的工艺参数和明确的质量标准,不同教师做法不一,且计量手段落后,概念模糊,制品质量不稳定,造成学生学习起来难度较大;实施面点工艺标准化教学,可使学生更快更好的掌握烹饪工艺和技能,同时增强了学生的标准化意识,为传统食品的工业化生产打好基础;工艺标准化是通过对教学品种的制作工艺进行定量研究,从它的原料性状、制作工艺、营养卫生、质量标准及饮食美学等几个方面着手,确定原料质量标准、制作工艺标准和产品质量标准来实现的。
