Hypermedia is an intensive integration of multimedia data and anchor links. The presence of multimedia data appends the temporal and spatial characteristics to the system and the anchors signify navigability in hypermedia applications. In this way the analysis and design methods for hypermedia applications would be involved with elaborating the presentation and navigation structures. In this pa...

Fuzziness is an important aspect of the uncertainties of spatial data. In this paper, the mechanism and methods of spatial modeling for fuzzy geographical objects are focused and the following two issues are resolved: (1) Modeling fuzzy geographical objects; (2) Modeling the relation between two fuzzy geographical objects. In the first issue, fuzzy geographical objects are defined by the novel ...

Systematic development of security sensitive software requires that there be a sufficiently expressive linguistic extension to modeling languages. We propose an extension to the Unified Modeling Language (UML) to satisfy this need. Our extensions are to the UML metamodel with a security policy constraint specification and enforcement module, business tasks and a history log for method calls. Us...

The design feature of KOMPSAT-2 simulator based on object oriented design methodology in terms of unified modeling language (UML) has been discussed in this paper. Also, we present how to embed flight software into the simulator. Flight software embedding for KOMPSAT-2 simulator is compared to that of the KOMPSAT-1 simulator.

This paper presents a conceptual modeling language for spatiotemporal applications that offers built-in support for capturing geo-referenced, time-varying information. More specifically, the well-known object-oriented Unified Modeling Language (UML) is extended to capture the semantics of space and time as they appear in spatiotemporal applications. Language clarity and simplicity is maintained...

Recent research works propose to use the Unified Modeling Language (UML) to design data warehouses. First, the paper overviews these recent UML-based techniques. We show that UML can help system designers to build a data warehouse model. This type of model aims to describe the different analysis dimensions of the data. Second, we will also present different UML-based tools used during a project...

Mobile Agents represent a crucial part in most agent-based systems. However, very little work has taken place in modelling such systems and, up to now, none of the existing agent oriented methodologies provide concepts and notations to fully capture mobile agents. In this work we are presenting extensions to the Unified Modeling Language (UML) to model mobile agents. We use three different scen...

oday’s businesses compete vigorously in a global market filled with opportunities and risks. They are bombarded with ongoing business and technological change as well as ever-increasing complexity that is partially due to their evolutionary response to change. Businesses are charted to solve complex and ever-changing problems for themselves and their clients by applying their knowledge within t...

The system family paradigm aims towards developing several applications out of a domain with just one underlying architecture. The foundation of this core architecture are common properties. With this prefabricated core, systems can be build faster. Modeling and development of common parts and variants have to be supported by methods and notations. This paper extends the Unified Modeling Langua...

With the objective of supporting user to enjoy a deep cultural experience, interactive learning tasks and elements are highly needed. It would be a good motivation for the user/visitor as a learner for enjoyable learning. In the previous work, we have proposed an adaptive context-aware model based on the user’s interests with Unified Modeling Language (UML) approach to supported cultural herita...
