一类G与G相交于一点的图的特征值     

任秋道 《绵阳师范学院学报》2007,26(11):14-17

图G的特征值是图的一个重要不变量。在量子化学和理论化学中有大量的应用。当图G的顶点数较大时,其邻接矩阵的阶数较大,计算特征值较困难。分块降阶是通常的方法。本文针对一些特殊图的邻接矩阵进行分块降阶求特征值。如果在V(G)上有一个一一映射φ,使得φ(vi)=vn-i 1,i=1,2,…,n,那么G的点v1仅与G的点v1重合的图G G的特征值中有G-V1的特征值。  相似文献   

Mitigating the Effects of Poverty and Crime: the Long-Term Effects of an Early Intervention Programme for Children who were Developmentally Delayed and Prenatally Exposed to Cocaine     

Mary Anne Ullery  Antonio Gonzalez  Lynne Katz 《International Journal of Disability, Development & Education》2016,63(4):403-418

This study explores the long-term impact on participation in the Linda Ray Intervention Program (LRIP) for children (n = 54) who were developmentally delayed and prenatally exposed to cocaine. By identifying a group of programme graduates from a high crime/high poverty neighbourhood in Miami-Dade County using ArcGIS 10.2 software, a quasi-experimental design was used to compare children living in this area who participated in the centre-based modality (5 h a day; 5 days a week) to children living in this area who participated in the home-based modality (3 h per week) on their Florida Comprehensive Assessment Test (FCAT) reading and math scale scores in public school. The children who participated in the centre-based modality reported stronger outcomes in both math and reading FCAT scale scores at the p < .05 level and also out-performed their school-age peers on both math and reading FCAT scores at the p < .05 level.  相似文献

Development of a competency mapping tool for undergraduate professional degree programmes,using mechanical engineering as a case study     

David W. Holmes  Madoc Sheehan  Melanie Birks  John Smithson 《European Journal of Engineering Education》2018,43(1):126-143

Mapping the curriculum of a professional degree to the associated competency standard ensures graduates have the competence to perform as professionals. Existing approaches to competence mapping vary greatly in depth, complexity, and effectiveness, and a standardised approach remains elusive. This paper describes a new mapping software tool that streamlines and standardises the competency mapping process. The available analytics facilitate ongoing programme review, management, and accreditation. The complete mapping and analysis of an Australian mechanical engineering degree programme is described as a case study. Each subject is mapped by evaluating the amount and depth of competence development present. Combining subject results then enables highly detailed programme level analysis. The mapping process is designed to be administratively light, with aspects of professional development embedded in the software. The effective competence mapping described in this paper enables quantification of learning within a professional degree programme, and provides a mechanism for holistic programme improvement.  相似文献
