Recent trends in technology and network use have pushed the capabilities required of the Internet beyond what the current infrastructure can provide. To address these limitations, the network community has developed a variety of technologies that can be used to support new and enhanced network services. A critical question that remains unanswered is how to get users and service providers to ado...

It is considered that Web services have had a tremendous impact on the web as a potential silver bullet for supporting a distributed service-based economy on a global scale. However, despite the outstanding progress, their uptake on a web scale has been significantly less than initially anticipated due to higher usage thresholds. For instance, it is a hard task for service provider to seek appr...

This paper presents the results of our empirical research in measuring the size and structure of the US information economy in 1992 and 1997, and in assessing the growth experienced by different industries and sectors since Porat’s research on the US information economy in 1967. The study indicates that the share of the information economy in total GNP grew from about 46 percent in 1967 to abou...

a r t i c l e i n f o Transportation optimization usually aims at minimizing the empty load ratios (ELRs) of vehicles. Most Chinese vehicles for logistics are owned by individual entrepreneurs. Because China is very large, transport distances are typically long, and thus the ELR is very high. The ELR is the primary reason for high transport costs, considerable pollution, and high energy consump...

In the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. This lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. In this paper, a “service-life factor” has been defined. Applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

Hard times affecting world-wide economy have strong consequences and are challenging IT departments from all sorts of enterprises. Expensive software projects are replaced by component-based agile systems and paradigms like SOA, REST, cloud computing are the new buzz-words. Behind the canvas, the service concept plays a central role, which we try to reveal
