Unlike the network TCP/IP's and OSI's layered structure of protocols, which allows the independence of protocols of different layers, as well as defining the upper layer protocols through the protocols of the lower layers, the cloud service layers are tightly dependent on each other. For example, an application of the SaaS layer can neither communicate nor exchange data with another application found...
The transformation of legacy MARC catalogs to FRBR catalogs (FRBRization) is a complex and important challenge for libraries. Although many FRBRization tools have provided experimental validation, it is difficult to evaluate and compare these systems on a fair basis due to a lack of common datasets. This poster presents two public datasets (T42 and BIB-RCAT) intended to support the validation of the...
Mobile agent technology is an emerging concept that becomes a new exciting field in computer science and being applied to a number of applications areas like: mobile computing, e-commerce, information retrieval, network management and telecommunications. The power of these agents in solving complex problems is due to many characteristics. They can achieve their goals in a flexible way by using interaction...
In this article we present a system capable of creating, managing and presenting digital portfolios. Our system innovates by using roles and states during its creation phase. This allows for high quality elements in the portfolio and promotes the students' reflection over them before full integration. The system also complies with the existing standards for e-portfolios. Moreover, it adds an extension...
Enlightened by some knowledge of ecology and swarm competition, an improved multigrouped particle swarm optimization based on migration and competition, namely PSOMC, is proposed for parameters estimation of non-linear systems. The PSOMC is not concerned with the evolution of a single population, but instead is concerned with the evolution of multiple parallel swarms; moreover it incorporates some...
Service-Oriented Architecture (SOA) is a way of designing, developing, deploying, and managing enterprise systems where business needs and technical solutions are closely aligned. SOA offers a number of potential benefits, such as cost-efficiency and agility. To exploit the benefits that SOA offers, several organizations are adopting a services model for leveraging their existing legacy systems. Migration...
International standardization in information representation, organization, and dissemination are meant to eliminate the discrepancies in communication among participating organizations and institutions in a particular domain. The management of domain information will then allow different participants to integrate their legacy information or application servers to a nation-wide network and use widely...
