The most important features of the proposed system include compressed domain indexing, searching by using scalable features, and progressive image transmission. User interaction is involved both at the search refinement stage and in the display of the query results. The most important query types include query by color layout and query by wavelet-coefficient clustering information. The indexing and searching algorithms are tightly coupled with the underlying image compression algorithm by which means the images are stored in the database, reducing both the complexity and the storage requirements of the database management system. In this research, we utilize our previously developed (B.-B. Chai et al., 1997, 1998) high-performance wavelet image coding algorithm, termed \"significance-linked connected component analysis\", which not only renders a very high compression performance when compared to other top-ranked wavelet image coding algorithms and the JPEG standard, but also inherently supports scalable features and progressive transmission. Computer experiments demonstrate the efficiency of the developed system.","PeriodicalId":376253,"journal":{"name":"Proceedings Seventeenth IEEE Symposium on Reliable Distributed Systems (Cat.

The traditional model of software design for large scale scientific problem solving is outdated. The emphasis is now on large teams that must build simulation software that integrates physical systems from multiple scientific disciplines. In addition to the problem of multi-disciplinary physics, the computational environment is now a grid of distributed resources consisting of large supercomputers, databases and networked instruments connected by high speed networks. Consequently, a new model for programming these applications is required. What is emerging is a programming style where the individual components of a large simulation can be located on remote systems and the application is built by composing these elements together to form a single distributed system. Building applications from software components is not a new idea. It has a rich history in the visualization and object oriented software design communities. More recently, the desktop top software industry has embraced this concept with systems like Java Beans, ActiveX and CORBA-Enterprise Beans. The author examines a new project to design a component architecture for scientific programming. He examines some of the design trade-offs that make this problem different from the conventional CA environment.","PeriodicalId":376253,"journal":{"name":"Proceedings Seventeenth IEEE Symposium on Reliable Distributed Systems (Cat.

The high availability comes at the cost of allowing inconsistent accesses, since users can read and write old copies of data. Session guarantees have been used to reduce such inconsistencies. They preserve most of the availability benefits of optimistic systems. We generalize session guarantees to apply to persistent as well as distributed entities. We implement these guarantees, called view consistency, on Ficus an optimistically replicated file system. Our implementation enforces consistency on a per-file basis and does not require changes to individual applications. View consistency is enforced by clients accessing the data and thus requires minimal changes to the replicated data servers. We show that view consistency allows access to available and high performing data replicas and can be implemented efficiently. Experimental results show that the consistency overhead for clients ranges from 1% to 8% of application runtime for the benchmarks studied in the prototype system. The benefits of the system are an improvement in access times due to better replica selection and improved consistency guarantees over a purely optimistic system.","PeriodicalId":376253,"journal":{"name":"Proceedings Seventeenth IEEE Symposium on Reliable Distributed Systems (Cat.

This is particularly true if they have dependability requirements that change during the execution of an application, and are built with commercial off-the-shelf hardware. In that case, fault tolerance must be achieved using middleware software, and mechanisms must be provided to communicate the dependability requirements of a distributed application to the system and to adapt the system's configuration to try to achieve the desired dependability. The AQuA architecture allows distributed applications to request a desired level of availability using the Quality Objects (QuO) framework and includes a dependability manager that attempts to meet requested availability levels by configuring the system in response to outside requests and changes in system resources due to faults. The AQuA architecture uses the QuO runtime to process and invoke availability requests, the Proteus dependability manager to configure the system in response to faults and availability requests, and the Ensemble protocol stack to provide group communication services. Furthermore, a CORBA interface is provided to application objects using the AQuA gateway. The gateway provides a mechanism to translate between process-level communication, as supported by Ensemble, and IIOP messages, understood by Object Request Brokers. Both active and passive replication are supported, and the replication type to use is chosen based on the performance and dependability requirements of particular distributed applications.","PeriodicalId":376253,"journal":{"name":"Proceedings Seventeenth IEEE Symposium on Reliable Distributed Systems (Cat.
