Recent theory and experimental work in metapopulations and metacommunities demonstrates that long-term persistence is maximized when the rate at which individuals disperse among patches within the system is intermediate; if too low, local extinctions are more frequent than recolonizations, increasing the chance of regional-scale extinctions, and if too high, dynamics exhibit region-wide synchro...

The purpose of this study is to examine the relationship between local government services and the overall satisfaction of users with the e–recruitment website (e–job website) in Taiwan. A two–dimensional mean value matrix (TDMVM) technique was used to explore the identification, classification, and application of website service quality. The results show that the asymmetrical relationship betw...

For real time embedded systems software performance is one of the most important quality attributes. Although a variety of general activities has been proposed as a basis for controlling and predicting the software performance in software, these activities are not widely used in the maintenance and evolution of embedded platforms. During the maintenance and evolution of an embedded platform, wh...

Data freshness has been identified as one of the most important data quality attributes in information systems. This importance increases especially in the context of systems that integrate a large set of autonomous data sources. In this paper we describe a quality evaluation framework which allows evaluation of data freshness in different architectural contexts. We also show how this quality f...

Attribute based encryption (ABE) is a good way to achieve flexible and secure access control to data, and attribute revocation is the extension of the attribute-based encryption, and the keyword search is an indispensable part for cloud storage. The combination of both has an important application in the cloud storage. In this paper, we construct a searchable attribute-based encryption scheme w...
