Using pooled time-series, cross-sectional data on 110 Australian companies over the period 1992-1998 an examination is undertaken whether the trademarked variant of residual income known as economic value-added (or EVA) is more highly associated with stock returns than conventional accounting-based measures. The accountingbased measures of internal and external performance include earnings, net...

The facility that allows users to query heterogeneous and distributed data repositories the majority of users. Moreover, that facility should hide all the intrinsic problems related to the context such as location, organi-zation/structure, query language and semantics of the data in various repositories. In this paper a query processing strategy that focuses on information content is presented....

Recently there has been an increasing deployment of content distribution networks (CDNs) that offer hosting services to Web content providers. In this paper, we first compare the un-cooperative pulling of Web contents used by commercial CDNs with the cooperative pushing. Our results show that the latter can achieve comparable users’ perceived performance with only 4 5% of replication and update...

Pooled time-series, cross-sectional data on 110 Australian companies over the period 1992-1998 is employed to examine whether the trademarked variant of residual income known as economic value-added (EVA) is more highly associated with stock returns than more conventional accounting-based measures. These other measures of internal and external performance include earnings, net cash flow and res...

In this paper, the dynamic behavior of square plates with various thicknesses and stiffening configurations subjected to underwater explosion (UNDEX) are evaluated through a relatively novel approach which is called Incremental Explosive Analysis (IEA). The IEA estimates the different limit-states and deterministic assessment of plats’ behavior, considering uncertainty of loading conditions and...

Background and Objectives: Information ethics, according to Islam, equals observing human rights and morals in dealing with information transmission and provision, which must be based on honesty and truthfulness. As Islam highly values society and social issues, it believes that human behaviors and interactions are strongly interconnected in a society. Committing to ethical issues regarding inf...

Many important strategic applications involve inter-corporate linkage or intra-corporate integration of information. This requires multiple databases to work together. We refer to this category of information systems as Composite Information Systems (CIS). Migrating from separate systems to a more fully integrated CIS environment is usually a difficult, expensive, and timeconsuming process both...

We propose a novel approach to the problem of simultaneous localization and mapping (SLAM) based on incremental smoothing, that is suitable for real-time applications in large-scale environments. The main advantages over filter-based algorithms are that we solve the full SLAM problem without the need for any approximations, and that we do not suffer from linearization errors. We achieve efficie...

genetic drift of germplasm in cultivated wheat is good motivation for studying genetic diversity in its wild relatives. in this study, r-rap, a new retrotransposon-based marker, was applied to assess the structure and genetic diversity of 30 accessions of aegilops sp. originating from different geographical regions of iran. the 15 r-rap primer combinations revealed a total of 338 bands ranging ...
