utonomous Underwater Vehicles (AUVs) share common A control problems with other air, land, and water unmanned vehicles. In addition to requiring high-dimensional and computationally intensive sensory data for real-time mission execution, power and communication limitations in an underwater environment make it more difficult to develop a control architecture(More)
The analysis and exploration of multidimensional and multivariate data is still one of the most challenging areas in the field of visualization. In this paper, we describe an approach to visual analysis of an especially challenging set of problems that exhibit a complex internal data structure. We describe the interactive visual exploration and analysis of(More)
This paper presents a framework for multi-user distributed virtual environments (VEs) and explores its application to teleoperation of a mobile robot over the Internet. The proposed framework, incorporating the functional and the interconnection models, attempts to represent common functionality, communication issues, and requirements found in distributed(More)
In order to demonstrate the correctness of a system, developers today must resort to either exhaustive testing or some combination of testing and formal verification following the use of appropriate methods in the development process. While formal methods have afforded numerous successes, their application today presents serious issues, e.g., costs to gear(More)
Agility metrics are difficult to define, mainly due to the multidimensionality and vagueness of the concept of agility. In this paper, a fuzzy logic knowledge-based framework is presented for the assessment of manufacturing agility. The combined measure incorporates certain operational parameters, their variations, and their effect on the value of agility.(More)
Most of the current research in wireless sensor networks (WSNs) is constraint driven and focuses on optimizing the use of limited resources (e.g., power) at each sensor. While such constraints are important, there is a energy for more general performance metrics to assess the effectiveness of WSNs. There is also a need for a unified formal model that would(More)
There is a large number of interactive visualization tools, however no universal tool exists that covers all relevant aspects for all possible application domains. We have developed a tool, ComVis, which was intended to be used as are search prototype for new visualization techniques. We have identified some interesting aspects from developers' and users'(More)
This paper describes the conceptual design of an interaction independence middleware framework and describes the role that web services plays within it. We investigate two pervasive service-oriented architecture paradigms, SOAP and REST, in order to gauge their potential effectiveness in meeting underlying back-end data transmission requirements; provide(More)
The Model Driven Architecture (MDA) approach uses a platformindependent model to define system functionality, or requirements, using some specification language. The requirements are then translated to a platform-specific model for implementation. An agent architecture based on the human cognitive model of planning, the Cognitive Agent Architecture(More)
User interface design and development for ubiquitous software applications is challenged by the presence of varying contexts. Context comprises of user’s computing platform, the environment in which the user is interacting with the application and user characteristics which comprise of user’s behavior during interaction and user preferences for interface(More)
