An ANN-based continuous Mandarin base-syllable recognition system is proposed. It adopts a hybrid approach to combine an HRNN with a Viterbi search. The HRNN is taken as a frond-end processor and responsible for calculating discrimination scores for all 411 base-syllables. The Vi-terbi search is then followed to nd out the best base-syllable sequence with highest score as the recognized output....

In recent years, a large number of dual-band antennas have been developed for wireless applications [1]-[6]. Most of these dual-band antennas are used for mobile terminals, such as cellular phones or laptop computers. For such applications, the desirable radiation patterns are usually omnidirectional. A unidirectional radiation pattern is sometime required for wireless base station and/or acces...

Distributed systems are vital for the efficient processing required in military and commercial applications. For many of these applications, it is especially important that the distributed data base management systems (DDBMS) operate in a secure manner. For example, the DDBMS should allow users, who are cleared at different security levels access to the data base at different levels of data sen...

Abstract. In this research work, we present a high-level prototyping of a new processor core based on Queue architecture as starting point for application-specific processor design exploration. Using modular design structure with control logic implemented as a set of communicating state machines, we show hardware emulation and optimizations results of a parallel queue proecssor architecture (Qu...

The ability to dynamically redefine the computational base of a processor is seen as a possible approach to improving the processor's performance. Provision of a facility to allow dynamic linking and loading of microprograms is considered as a practical means of accomplishing this modification. The feasibility and the desirability of this approach is evaluated in terms of the implementation ove...
