Cloud services allow for hosting applications partially or completely in the Cloud by migrating their components and data. Especially with respect to data migration, a series of functional and non-functional challenges like data confidentiality arise when considering private and public Cloud data stores. In this paper we identify some of these challenges and propose a set of reusable solutions ...

In the upgrade process of enterprise information systems, whether new systems will be success and their development will be efficient, depends on how to deal with and utilize those legacy systems. We propose an evaluation system, which comprehensively describes the capacity of legacy information systems in five aspects. Then a practical legacy systems evaluation method is scripted. Base on the ...

Because of the global warming and the rising sea level, residents living in southwestern coastland, Taiwan are faced with the submerged land and may move to higher elevation area. It is desirable to discuss the key consideration factor for selecting the migration location under five dimensions of security”, “health”, “convenience”, “comfort” and “socio-economic” based on the document reviews. T...

The present research is an introductory paper on Synthetic Aperture Radar (SAR) systems. A review on topics and techniques related to the longrange and shortrange SAR systems are presented. The longrange SAR image is constructed using RangeDoppler Algorithm (RDA); while the RangeMigration Algorithm (RMA) is implemented with shortrange SAR for image formation. The simulation results indica...

A automatic human tracking system using mobile agent technology is realized because a mobile agent moves in accordance with a migration of a target person. In this paper, we propose a method for determining the neighbor node in consideration of the imaging range of cameras. Keywords—Human tracking, Mobile agent, Pan/Tilt/Zoom, Neighbor relation.
