The present study introduced a novel hierarchical hub set covering problem with capacity constraints. This study showed the significance of fixed charge costs for locating facilities, assigning hub links and designing a productivity network. The proposed model employs mixed integer programming to locate facilities and establish links between nodes according to the travel time between an origin-...

We have defined a model for multidimensional hyperpresentations, in which time-varying multimedia presentations are dynamically linked together. In our model a hyperlink’s context can change over time. Thus, at any time during a continuous presentation, a user can interactively access context-specific information. How the hyperlinks are traversed depends upon user interaction and/or context-sen...

We investigate the economic hubs and authorities of the world trade network (WTN) from 1992 to 2012, an era of rapid economic globalization. Using a well-defined weighted hyperlink-induced topic search (HITS) algorithm, we can calculate the values of the weighted HITS hub and authority for each country in a conjugate way. In the context of the WTN, authority values are large for countries with ...

Social network analysis (SNA) is based on a conceptual network representation of social interactions and is an invaluable tool for conservation professionals to increase collaboration, improve information flow, and increase efficiency. We present two approaches to constructing internet-based social networks, and use an existing traditional (survey-based) case study to illustrate in a familiar c...

In recent years, email is the basic service for person to person communication, and email facilitates by its high speed, and process ability. The email malware exhibits two new propagation features; reinfection and self-start. Reinfection is the process by which an infected user sends out malware copies, whenever the infected user opens the malicious hyperlink or attachment. Self-Start is the p...

In this contribution we consider the construction of hyperdocuments; converting scanned paper documents into electronic hypertext. Hyperlink creation is automated by analyzing the structure and content of the scanned document. The focus is on hyperlinks between the text and labels in a picture. A number of tools for such hyperlink detection are described. Practical results are presented.
