成果导向背景下二级教学质量监控的责权划分研究

围绕当前高校内部校级教学质量监控规模过大导致的校级督导工作难以满足学校发展要求这一难题，本文通过引入成果导向理念，厘清学校与院系的教学质量管理权责范围，提出了二级教学质量监控权利分配策略，实现了校院两级教学质量监控的有效衔接，改变了“原地踏步式”的教学质量监控现状。     

Modeling War as a Business Process with the Assistance of Service Oriented Architecture

The pace of war is increasing since militaries are adopting the ideas of NCW （network centric warfare）. Therefore, the process of war has to be modeled into the BP （business process） in order to benefit from available resources in real-time. There is an increasing need to automate command and control tools utilized in military operations because of the versatility and increase d tempo of operations. Operations can be commanded and orchestrated with the assistance of SOA （service oriented architecture）. SOA is currently seen as a technology that can satisfy these needs of NCO （network centric operations）. The BPs are chains of logic that request SOA services. This paper argues that in the case of a military setting, in order to achieve maximum impact with minimal effort （cf. downsizing）, military operations need to be modeled as BPs （e.g., a dismounted company attack）. This asks for using a RM （resource manager）, a scheduler and a BSS （battle secure scheduler） in allocating the requested services （e.g., processing a fire support order）. In the future, a single FFW （future force warrior）, an essential performer in military operations, can benefit from the BPs approach via enhanced performance, improved SA （situational awareness） and with decreased instances of fratricide. This introduced model examines war as a business process with the assistance of SOA and discusses how a business process--like orchestration of systems and services can improve the overall performance in given military settings.

基于面向分类准则的维数约简及其在人脸识别中的应用

针对高维数据导致的维数灾难问题,提出了一种基于面向分类准则的维数约简方法。所提准则使每个训练样本在特征空间中与同类样本尽可能接近,而与异类样本尽可能疏远。首先对每个训练样本定义同类样本加权平均距离和异类样本加权平均距离。然后基于上述两个概念分别定义总体同类距离和总体异类距离。以最小化总体同类距离和最大化总体异类距离为目的提出了面向分类的准则(Classification Oriented Criterion,COC)。最后,基于面向分类的准则推导出了一种新的维数约简方法。在公共人脸数据库ORL和Yale上的实验表明所提方法性能优于有代表性的维数约简方法。

Preparation and Characterization of Mordenite Thin Films via Pulsed Laser Deposition

Zeolite thin films are interesting for their potential application in membrane based separations, catalysis, and molecular sensing. Mordenite is a one-dimensional channel type zeolite that has been used in alcohol/water separations. Pulsed-laser deposition has been used to prepare partially oriented, crystalline mordenite thin films on stainless steel foil, and frits as well as carbon fibers and DAM-1 particles. Preliminary results for pervaporation of isopropanol/H₂O mixtures using mordenite membranes indicate separation factors of 133 and 459 at room temperature and 76°C, respectively.

Phase morphology and toughening mechanism of polyamide 6/EPDM-g-MA blends obtained via dynamic packing injection molding

One of the most important findings in polymer-toughening is known as the critical matrix ligament thickness (τ_c) theory, which is directly related to both rubber concentration and average size of particles. All these studies assume that rubber particles are spherical and randomly distributed in the matrix. Rubber particles may be stretched and oriented along the shear flow direction in real processing. In this paper the effect of stretched and oriented rubber particles on the impact strength of PA6/EPDM-g-MA blends have been studied via dynamic packing injection molding (DPIM). The impact strength of specimens obtained by DPIM was found substantially increase at all the blends investigated, compared with the one obtained via conventional injection molding. Particularly, more than 30 kJ m⁻² increase of the impact strength was observed for specimens with a higher rubber content (more than 15 wt%). SEM results showed a remarkably decrease of rubber particle size and more uniform dispersion of the dynamic molded specimens. This can be attributed to the shear induced reaction at the interface between polyamide 6 and EPDM-g-MA during the packing stage. The rubber particles were found stretched along the melt shear flow direction when it is content above 15 wt%. A master curve can be also constructed by plotting the impact strength versus the inter-particle distance, indicating that Wu's criterion still works for blends with stretched and oriented rubber particles when the crack propagation direction is perpendicular to the orientation direction of rubber particles. The observed higher impact strength in dynamic specimens could be due to, in part, the enhanced flexural stiffness, which will absorb more energy during impact process when the fracture of IZOD bars is incomplete, but more importantly due to the existence of the stretched and oriented rubber particles, which are more efficient in slowing the velocity of crack propagation and thus cause higher impact resistance when the fracture propagation direction is perpendicular to the rubber oriented direction.
