    Semantic-Based Query Answering Supported by Association Patterns and Materialized Views

    Querying a database is a common task for most database systems. To query a database is to find some answers from stored data. Traditional database systems return exactly what is being asked. This is a method of direct query answering and users are required to construct a query intelligently and...

    Database Reverse Engineering Based on Association Rule Mining

    Maintaining a legacy database is a difficult task especially when system documentation is poor written or even missing. Database reverse engineering is an attempt to recover high-level conceptual design from the existing database instances. In this paper, the authors propose a technique to discover conceptual schema using the association mining...

    Fast Dummy Sequence Insertion Method for PAPR Reduction in WiMAX Systems

    In literatures, many researches proposed various methods to reduce PAPR (Peak to Average Power Ratio). Among those, DSI (Dummy Sequence Insertion) is one of the most attractive methods for WiMAX systems because it does not require side information transmitted along with user data. However, the conventional DSI methods find dummy...

    A Monte Carlo Method to Data Stream Analysis

    Data stream analysis is the process of computing various summaries and derived values from large amounts of data which are continuously generated at a rapid rate. The nature of a stream does not allow a revisit on each data element. Furthermore, data processing must be fast to produce timely analysis...
