Provable data possession (PDP) is a technique for ensuring the integrity of data in storage outsourcing. In this paper, we address the construction of an efficient PDP scheme for distributed cloud storage to support the scalability of service and data migration, in which we consider the existence of multiple cloud service providers to cooperatively store and maintain the clients’ data. We prese...

Informledge System (ILS) is a knowledge network with autonomous nodes and intelligent links that integrate and structure the pieces of knowledge. In this paper, we put forward the strategies for knowledge embedding and retrieval in an ILS. ILS is a powerful knowledge network system dealing with logical storage and connectivity of information units to form knowledge using autonomous nodes and mu...

We present a general hypertext data model supporting the integration (GHMI) of hypertext and information systems. The information systems benefit from hypertext functionality while preserving their computation capabilities. Although systems supporting integration of hypertext and display-oriented information systems do exist, no model or system effectively supports integrating hypertext and com...

This paper addresses the problem of efficiently operating the storage devices in an electricity microgrid featuring photovoltaic (PV) panels with both shortand long-term storage capacities. The problem of optimally activating the storage devices is formulated as a sequential decision making problem under uncertainty where, at every time-step, the uncertainty comes from the lack of knowledge abo...

Reservoir routing is often conducted with the stage-storage curve of the storage facility. Often at a planning stage, little hydraulic information about the storage facility is known yet. Therefore, a performance curve such as the storage-outflow curve needs to be developed from hydrologic information without detail basin geometry and outlet hydraulics. This paper presents a hydrology based pro...

Tertiary storage devices have long been in use for storing massive amounts of data in le-oriented mass storage systems. However, their use in database systems is relatively new. Database systems associate more structure to the data than just raw sequence of bytes. Hence if they are allowed control of the tertiary memory devices, they can greatly reduce access cost by doing more informed caching...
