Topological Characterization of Book Graph and Stacked Book Graph

Degree based topological indices are being widely used in computer-aided modeling, structural activity relations, and drug designing to predict the underlying topological properties of networks and graphs. In this work, we compute the certain important degree based topological indices like Randic index, sum connectivity index, ABC index, ABC₄ index, GA index and GA₅ index of Book graph B_n and Stacked book graph B_m,n. The results are analyzed by using edge partition, and the general formulas are derived for the above-mentioned families of graphs.

纸板类儿童卡书抗弯曲性能影响因素研究

文章针对四种制备儿童卡书的卡纸进行研究,分析了卡纸纤维结构类型和表面粗糙度对儿童卡书变形度的影响。对水性胶粘剂固含量与儿童卡书弯曲度的关系研究发现胶粘剂固含量在60%~65%时,制备的卡书抗弯曲性能较好。此外,研究发现后处理环境条件选用温度23±3℃,湿度50±5%的标准条件,后处理时间为1个月左右得到的儿童卡书的弯曲变形度最小。

本文介绍了一种多士炉隔网的自动化制作方法及其配用的两种隔网开合机构。与传统的人工制作隔网及其隔网开合机构相比,自动化制作隔网的方法及其配用的隔网开合机构并不复杂,但其产生的经济效益非常显著。     

A RECONSTRUCTION OF THE KEY TO BEALE CIPHER NUMBER TWO

A reconstruction of the key used to encrypt B2 (Beale Cipher Number 2) reveals greater statistical anomalies in Bl than previously reported by Gillogly [8]. The 1885 pamphlet versions of the ciphers are used in this analysis. Several explanations of these anomalies are discussed. The application of artificial intelligence techniques to automated cryptanalysis of the Beale Ciphers is discussed.     

The effect of electronic books on enhancing emergent literacy skills of pre-school children

The purpose of this study was to investigate the effects of e-books on enhancing Jordanian preschool children's emergent literacy skills (experimental group), in comparison to children who were exposed to regular printed books (control group). To achieve the objectives of this study, the total of 92 children were assigned to either experimental group (n = 48) and control group (n = 44). The pre- and post-test data was collected on print awareness, vocabulary, alphabetic knowledge and phonological awareness skills to determine the effectiveness of e-books. The results indicated that children in experimental group performed significantly better than the children in control group. Moreover, significant differences were found according to gender, as the female children exhibited superior emergent literacy skills to the male children. Regarding the different emergent literacy skills, children in the experimental group achieved better improvement in the areas of print awareness and vocabulary. Based on these findings, it is recommended that pre-school institutions incorporate e-books activities into their classrooms.
