Computing and STEM in Greek tertiary education: gender representation of faculty members during the decade 2003–2013

This study focuses on the investigation of gender representation of faculty members of all ranks (professors, associate professors, assistant professors and lecturers) of Computing and STEM (Science, Technology, Engineering and Mathematics) in Greek tertiary education during the decade 2003–2013. To this end, a quantitative study was conducted, taking into account appropriate data derived from the Hellenic Statistical Authority. The data analysis shows that during the said decade, (a) faculty members in Computing and in each discipline of STEM constituted a small part of the total number of Greek faculty members; (b) for every single year of the decade, females were less prevalent than males in all ranks of faculty members in Computing and Engineering; (c) the situation for females in the Computing faculty appears to have been even worse, as the percentage of them in every rank was the lowest among the STEM disciplines studied for all or most of the years of the decade under study; and (d) although females were better represented in the position of lecturer, which constituted the fewest faculty members in the aforementioned disciplines, highly populated ranks of faculty members were dominated by males.

The Analysis of Epiphany in A Little Cloud

A Little Cloud is one of the short stories in James Joyce’s Dubliners which can be regarded as a container of smaller epiphanies since“epiphany”is used as a predominant psychological device. This artic...     

关于不可逆矩阵特征值的计算

计算矩阵特征值的常规方法就是求其相应的特征多项式的根.然而,当矩阵的特征多项式次数超过5次时,其根的求解没有公式可循,因而计算相当困难.为此,通过讨论不可逆矩阵特征多项式的结构问题,从而得到其特征值计算的一种便捷方法.     

梦中来复少年身：谈金庸短篇小说《月云》

金庸2000年发表的短篇小说《月云》,是一篇自传色彩很浓的作品。男主人公童年宜官真诚对待弱小者丫环月云,并对她产生＂主人——婢女＂模式的朦胧情愫,整个作品流露出忆念江南的＂江南情结＂,都可以看成是金庸后来创作的武侠小说中倡导平等博爱思想、描写＂一男多女＂式情感关系、对江南和其他地域的描写笔法各异的源头。作者通过追忆童年经历,实际上为自己的武侠小说创作和人生道路做出了某种自我诠释,这篇小说是透视金庸其人及其作品的一扇窗口。     

CloudChain: A novel distribution model for digital products based on supply chain principles

Cloud computing is a popular outsourcing solution for organizations to support the information management during the life cycle of digital information goods. However, outsourcing management with a public provider results in a lack of control over digital products, which could produce incidents such as data unavailability during service outages, violations of confidentiality and/or legal issues. This paper presents a novel distribution model of digital products inspired by lean supply chain principles called CloudChain, which has been designed to support the information management during digital product lifecycle. This model enables connected networks of customers, partners and organizations to conduct the stages of digital product lifecycle as value chains. Virtual distribution channels are created over cloud resources for applications of organizations to deliver digital products to applications of partners through a seamless information flow. A configurable packing and logistic service was developed to ensure confidentiality and privacy in the product delivery by using encrypted packs. A chain management architecture enables organizations to keep tighter control over their value chains, distribution channels and digital products. CloudChain software instances were integrated to an information management system of a space agency. In an experimental evaluation CloudChain prototype was evaluated in a private cloud where the feasibility of applying supply chain principles to the delivery of digital products in terms of efficiency, flexibility and security was revealed.

Surface reconstruction by offset surface filtering

The problem of computing a piecewise linear approximation to a surface from its sample has been a focus of research in geometry modeling and graphics due to its widespread applications in computer aided design. In this paper, we give a new algorithm, to be called offset surface filtering (OSF) algorithm, which computes a piecewise-linear approximation of a smooth surface from a finite set of cloud points. The algorithm has two main stages. First, the surface normal on every point is estimated by the least squares best fitting plane method. Second, we construct a restricted Delaunay triangulation, which is a tubular neighborhood of the surface defined by two offset surfaces. The algorithm is simple and robust. We describe an implementation of it and show example outputs.
