This paper deals with the analysis and application of queueing models for single and multi stage flexible manufacturing systems that are subject to resource failure. Exact results are derived for the single stage queueing system. Two approximations are presneted for the multi stage queueing system as a closed network. We validate the approximations by comparing their performance estimates against the exact global balance solution. 相似文献

The present study reports on the construction of a dimensional measure of gender identity (gender dysphoria) for adolescents and adults. The 27-item gender identity/gender dysphoria questionnaire for adolescents and adults (GIDYQ-AA) was administered to 389 university students (heterosexual and nonheterosexual) and 73 clinic-referred patients with gender identity disorder. Principal axis factor analysis indicated that a one-factor solution, accounting for 61.3% of the total variance, best fits the data. Factor loadings were all ≥ .30 (median, .82; range, .34–.96). A mean total score (Cronbach's alpha, .97) was computed, which showed strong evidence for discriminant validity in that the gender identity patients had significantly more gender dysphoria than both the heterosexual and nonheterosexual university students. Using a cut-point of 3.00, we found the sensitivity was 90.4% for the gender identity patients and specificity was 99.7% for the controls. The utility of the GIDYQ-AA is discussed. 相似文献

AbstractIn 2015, the Big Ten Academic Alliance (BTAA) Libraries formed the BTAA Library E-Resource Accessibility Group. This group, which consists of members from each Big Ten library and the BTAA Library Initiatives staff, was charged with creating boilerplate accessibility license language for vendor contracts, as well as collectively funding high level accessibility testing of e-resources and posting these publicly for all libraries and users. Since the creation of the group, about 50 databases have been tested and accessibility license language has been created that can be used and adapted by anyone. In 2019, the group welcomed another consortia, the Association of Southeastern Research Libraries (ASERL), to be partners in this work, renaming themselves the Library Accessibility Alliance. This paper examines the mission, accomplishments, and new partnership in more depth while also discussing the need for focused efforts to help ensure accessible e-resources. 相似文献

泰戈尔在某部小说中说,女性手中的花环,要么挂在禽兽的恶汉脖子上,要么献给强同虚构人手般空想。因为女性在心底深处,渴望被肉欲的车轮碾碎,又或者在思想的烈火中融化--这种言辞似乎过于极端,好像女人都像受虐狂--不过,女人确实热爱幻想田人的强大,或肉体,或精神. 相似文献

Using data from individuals who earned a Ph.D. in economics in 1996-97, this study identifies factors associated with securing full-time permanent positions and determinants of starting salaries for new Ph.D. economists. Where individuals attend graduate school and factors including the field of specialization and work as a teaching/research assistant impact whether graduates obtain full-time permanent jobs. Choice of graduate program and amount of time spent in the program influence starting salary, as does obtaining a position outside academia or in a research-oriented academic institution, both of which entail higher salaries relative to employment at a B.A.-level academic institution. 相似文献
