Particularly, they can be interpreted in some situations as the energy levels of an electron in a molecule or as the possible frequencies of the tone of a vibrating membrane. The diameter of a graph, the maximum distance between any two vertices of a graph, has great impact on the service quality of communication networks. So we were motivated to investigate the sharp lower bound of the least eigenvalue of graphs with given diameter. Let gn. d be the set of graphs on n vertices with diameter d. For any graph G ∈ gn, d, by considering the least eigenvalue of its connected spanning bipartite subgraph, we obtained the sharp lower bound of the least eigenvalue of graph G. Furthermore, an upper bound of Laplacian spectral radius of graph G was given.展开更多

They must be inquisitive, able to delve into motivations, operations and justifications underlying the behavior of white collar criminals. They must be able to simplify technical accounting information and convey it effectively orally and in writing to a court or tribunal; be able to trace information via information technology tools; have an understanding of the adversarial legal system and the rules of evidence. Universities offering forensic accounting courses in various formats are on the increase. The aim of this paper is to investigate the subject areas that any course specializing in forensic accounting needs to cover.展开更多

This paper aims at a general analysis of the characteristics of the modem society and its impact on translation teaching. Meanwhile, this paper provides the translation teachers with some teaching methods and concepts. Finally, this paper points out that translation teachers must take the characteristcs of the modem society in the new century into consideration, and tries to follow some new ideas when teaching translation so as to adapt to the social changes and achieve the goal of translation teaching in the universities.展开更多

Its importance is escalating with the accelerated pace of global information. Information security is a comprehensive discipline involving computer science, network technology, communication technology, cryptography, information security technology, applied mathematics, number theory, information theory and other disciplines. It mainly refers to the condition that network hardware, software and system data are protected from destruction, change and divulgation from accidental or malicious reasons so that the system can run continuously and reliably with no interrupted network service.展开更多

The conceptualisations and classifications of these, however, are often ambiguous, overlap or lag behind in scientific literature. This article examines whether there is a common denominator to define and delimitate–and ultimately map–these new dimensions of cityscapes. In an extensive literature review we analysed and juxtaposed some of the most common concepts such as megacity, megaregion or megalopolis. We observed that many concepts are abstract or unspecific, and for those concepts for which physical parameters exist, the parameters are neither properly defined nor used in standardised ways. While understandably concepts originate from various disciplines, the authors identify a need for more precise definition and use of parameters. We conclude that often, spatial patterns of large urban areas resemble each other considerably but the definitions vary so widely that these differences may surpass any inconsistencies in the spatial delimitation process. In other words, today we have tools such as earth observation data and Geographic Information Systems to parameterise if clear definitions are provided. This appears not to be the case. The limiting factor when delineating large urban areas seems to be a commonly agreed ontology.展开更多
