Conflation is the complex process of recognizing and removing inconsistencies in geographical feature datasets that are stored in multiple databases. Specifically, we show how the technological advantages of an agent system can be combined with expert system techniques to provide a feasible system architec ture for distributed conflation. Our work utilizes expert systems in the multi-agent based infrastructure to perform a distributed conflation algorithm. Here, we present our system design, which utilizes both static and mobile agents.

Since agent technology may provide the suitable framework for developing such a system (as it can deal in a natural way with the distributed heterogeneous nature of the data) a problem of selection of the most appropriate agent environment needs to be addressed. In this paper, four mobile agent systems (Aglets, Concordia, Grasshopper, Voyager) are compared from the perspective of their suitability for this project.

A neural network approach is suggested to combine the completeness of information provided by a geometric modeler with the uncertainty required in the grouping process. The utilization of highly connectionist systems in such an environment is investigated. The advantages and shortcomings of these systems are discussed.

Multimedia data is defined as data in the form of text, sound and images. Manipulating and accessing such type of data requires an extensive approach for building a database system.

Here this paper we proposed a Novel Distributed Database Architectural Model for Mobile Cloud Computing (NDDAMMCC). Due to the exponential growth of wireless technologies and internet which are following Nielsen's Law of Internet Bandwidth, we are in the new era of cloud computing. In the recent technological era, smart mobile devices play a big role in all sort of day-by-day human needs. The applicability is so huge that the number of apps install on a mobile system becomes a hazard due to local memory limitations for mobile phone users and demands an alternative approach to solve this local memory problems. Mobile Cloud Computing (MCC) is the ultimate solution to this issue and our model presents a promising path in this new kind of cloud computing technology.

An account of how Neural Networks may be incorporated to provide control is such a setup. The example used in this paper is the problem of controlling a High Frequency Acoustics Platform (HFAP) in-flight. The HFAP is towed by a ship and flown in the water behind the ship to acquire acoustic data reflected from the sea floor. The stability of such a platform is of prime importance to the accuracy of data collected. Using fight data from previous runs of the platform, a Neural Network is trained. The trained network is then used to predict the behavior of the platform. These predictions may then be directly translated to control signals minimizing the platform&#39;s spatial deviations. In this paper results form the trained Neural Network on predicting the behavior of the platform are displayed. Network prediction results illustrating the ability of the network to operate with partial input are displayed. Displaying these results in contrast with conventional controller results given the same input parameters emphasizes the importance of such a feature. Finally the use of different network architectures and the cost of using these network, in terms of computing power is investigated.
