  • 2004 IEEE International Workshop on Biomedical Circuits & Systems IP-based Real-time Transmission System for Chromatic Medical Ultrasound Active Images
    2004
    Co-Authors: Qianming Shao, Minhua Qiu, Yaohua Zhou, Hong Liu
    Abstract:

    An IP-based real-time transmission system for chromatic medical ultrasound active images is presented. This system separates the luminance and chromatic signal of the image, and an adaptive segmentation method is used for the image compression. On the server side, a PC is used as a platform for operations and management. The DSP boards, inserted into the PCI siot of the PC, implements the real-time image compression, while the PC implements image sampling, data scheduling, client authentication, image data management and transmission. The client is totally implemented on a PC, it sets up a Remote Connection, receives and decodes the code, displays and stores the image data. When running on the network, the speed is 10-12 frames per second and the quality of the rebuilt images meets the medical requirement.

  • Security Aspects of Wireless Heterogeneous Databases- Protocol, Performance, and Energy Analysis1
    2015
    Co-Authors: Harshal Haridas, Ali R. Hurson, Yu Jiao
    Abstract:

    Users have been demanding information “anytime, anywhere”. The notion of accessing diverse and autonomous information repositories with different APIs is not accepted. This has necessitated the logical integration of diverse information from different sources with common APIs. Current multi-database researchers have addressed effectively issues such as local autonomy, heterogeneity, transaction management, concurrency control, transparency, and query resolution in a “sometimes, somewhere ” environment. The concept of mobility, however, introduces additional complexities and restrictions to multi-database designers. A user accessing data through a Remote Connection with a portable device has high probability to face issues like reduced capacity network Connections, frequent disConnections, and processing and resource restrictions. This work extends the scope of our previous effort in the design of an authorization model for a multi-database system. The Authorized Summary Schema Model is used as the underlying paradigm and is extended to provide a secure wireless environment. The proposed system is simulated and the impact of a wireless medium on performance is presented, evaluated, and analyzed

  • database system architecture a walk through time from centralized platform to mobile computing keynote address
    Lecture Notes in Computer Science, 2005
    Co-Authors: Ali R. Hurson, Yu Jiao
    Abstract:

    Classical distributed database systems monolithically offer distribution transparency and higher performance. This is made possible by making data available and closer to the application domain(s) that uses it by means such as the data distribution, duplication, and fragmentation. However, with the advances in technologies this monolithic and top down approach becomes insufficient. In the new networked computational environment, the data distribution issue has evolved into data integration from several heterogeneous and autonomous data sources. Heterogeneous distributed databases are designed to deal with issue of data integration and interoperability. They are developed to allow timely and reliable access to heterogeneous and autonomous data sources in an environment that is characterized as “sometime, somewhere.” The concept of mobility, where users access information through a Remote Connection with portable devices, has introduced additional complexities and restrictions to the heterogeneous distributed database system. This keynote address first introduces a three dimensional space to classify and identify the evolution of different classes of database systems. It also extensively discusses Heterogeneous Distributed Database Systems (HDDBS) and Mobile Data Access Systems (MDAS). Finally, it will address several research issues and their potential solutions.
