| 1 | Effective simulation of flexible lateral boundaries in two-and three-dimensional DEM simulations显示文摘Discrete element method (DEM) models to simulate laboratory element tests play an important role in advancing our understanding of the mechanics of granular material response, including bonded or cemented, particulate materials. Comparisons of the macro-scale response observed in a real physical test and a 'virtual' DEM-simulated test can calibrate or validate DEM models. The detailed, particle scale information provided in the DEM simulation can then be used to develop our understanding of the material behaviour. It is important to accurately model the physical test boundary conditions in these DEM simulations. This paper specifically considers triaxial tests as these tests are commonly used in soil mechanics. In a triaxial test, the test specimen of granular material is enclosed within a flexible latex membrane that allows the material to deform freely during testing, while maintaining a specified stress condition. Triaxial tests can only be realistically simulated in 3D DEM codes, however analogue, 2D, biaxial DEM simulations are also often considered as it is easier to visualize particle interactions in two dimensions. This paper describes algorithms to simulate the lateral boundary conditions imposed by the latex membrane used in physical triaxial tests in both 2D and 3D DEM simulations. The importance of carefully considering the lateral boundary conditions in DEM simulations is illustrated by considering a 2D biaxial test on a specimen of frictional unbonded disks and a 3D triaxial test on a bonded (cemented) specimen of spheres. The comparisons indicate that the lateral boundary conditions have a more significant influence on the local, particle-scale response in comparison with the overall macro-scale observations. | Geraldine Cheung Catherine O'Sullivan | 2008 | Particuology2008，6，6： | 17 |
| 2 | 我国内地旅游网站的可用性研究--基于对海口市网民的调查显示文摘目前国内很多针对旅游网站的研究大多是关注旅游网站的功能,网站可用性方面的研究很大程度上被忽视了。本文对此进行了探索性研究:通过采用修正的启发式评价方法,定义了用户对网站评价的基准,对489份基于5大类24个指标的调查问卷进行了分析和讨论,发现了我国内地旅游网站在可用性如内容服务形式、整体结构设计等方面存在的问题,同时给出了解决这些问题的建议和措施。 | 胡涛 Catherine Cheung Rob Law | 2008 | 旅游科学2008，22，4： | 11 |
| 3 | 基于员工专业学习满意度的酒店管理教育质量评价显示文摘目前,全球旅游酒店教育机构在教学方法与教育对象方面的研究仅局限于在大学这一封闭系统内展开,对酒店业界,特别是酒店员工对酒店管理专业教育的评价关注不够。文章在问卷调研的基础上,研究了中国星级酒店员工对酒店管理专业学习的满意度,以此视角评价国内酒店管理教育质量。研究发现,工作经验与就业技能教育对于酒店员工专业学习满意度贡献最大。同时,酒店员工专业学习满意度在性别、收入水平、教育水平方面有显著差异,在年龄、婚姻状况、酒店的任职部门与星级方面差异不显著。 | Catherine Cheung 杨惠君 韩国圣 | 2013 | 旅游研究2013，5，4： | 3 |
