The voltage-controlled oscillator (VCO), pre-scaler of divide-by-8, phase frequency detector (PFD), and charge pump (CP) have been developed with 0.25-/spl mu/m CMOS process. A 3rd order external loop filter has been optimized to reduce the lock-in time. The fractional-N divider and 3rd order /spl Delta//spl Sigma/ modulator have been designed with the VHDL codes, and implemented through the FPGA board of the Xilinx Spartan2E. The VCO has been designed to span from 900 MHz to 950 MHz band using LC resonator, and a fractional-N divider uses a 36/37 modulus and 3rd order /spl Delta//spl Sigma/ modulator to reduce the fractional spur. The measured result shows that the RF output power of the frequency synthesizer is -10 dBm, the phase noise is -78 dBc/Hz at 100 KHz offset frequency, the minimum frequency step is 10 kHz, and the maximum lock-in time is around 800 ms with 10 MHz step change.","PeriodicalId":129377,"journal":{"name":"Proceedings.

In this paper we present a new acoustic model based on vector quantization (VQ), which is better-suited for the limitations of the mobile environment. The proposed model is contrasted against finite state vector quantization (FSVQ), a commonly used technique is such environments. Performance enhancements include temporal restrictions to state generation, a flexible number of vectors per state, and updates of the traditional state transition function to a higher order. Experimental results show that the new model improves the recognition rate and reduces the computation load.","PeriodicalId":129377,"journal":{"name":"Proceedings.

Among the dominant methods, rule induction algorithms such as ID3 and C4.5 are widely used to extract rules from examples. The thrust of these algorithms is how they discriminate the given attributes based on information measure for building and determining the nodes in the decision tree. In particular, the main focus of these algorithms is on how to select the most appropriate attribute at each level of the decision tree process. This paper proposes an algorithm for rule induction for continuous data. The proposed algorithm uses an analysis of variance criterion for information measure in discriminating the given attributes for building the decision tree for continuous data.","PeriodicalId":129377,"journal":{"name":"Proceedings.

The paper is structured to first provide the theoretical foundation of the models in this area and the associated drivers for each model.

Security from a systems perspective involves limiting and controlling accessibility to the services provided by that system. Existing authorization mechanisms do not provide the tools for the ever-changing paradigm associated with distributed networks such as the Internet, and deployment of mobile and pervasive computing devices that users attach to these networks. A self-authorizing system for authentication in a distributed environment is a concept that addresses some of the inadequacies of a traditional authentication mechanism. This paper examines existing authorization and authentication methods and their respective inadequacies, while developing the concept of self-authorization and the basic principles that underlie transparency and re-authentication.","PeriodicalId":129377,"journal":{"name":"Proceedings.

The last decade has seen an increased number of tools to facilitate virtual classrooms and collaboration. However, feedback and evaluation are only partially automated in online courses. This paper largely follows knowledge management theories and artificial intelligent techniques, developing a framework to capture and manage automated responses to student replies. The instructor's tacit knowledge plays a direct role in augmenting class participation, learning communities, and feedback evaluation. Conceptual graphs are proposed to extract tacit knowledge from instructors written responses and to assist in externalizing it for future re-use. A question answering task is presented to illustrate the relationship between mental models and conceptual graphs and the mechanism to select responses through keyword match.","PeriodicalId":129377,"journal":{"name":"Proceedings.

In this paper, we give our motivation for JXPL and describe JXPL so that others may use the language. To aid our discussion, we introduce the grammar for JXPL using the extended Backus Naur form (EBNF). We also include examples and detail predefined functions.

When one end-point is in an IPv4 addressing domain, and the other is in an IPv6 addressing domain, a NAT-PT gateway must be used at the network level, to translate the protocol headers. The message bodies are altered by an application level gateway (ALG), to reflect the changed addresses. However, this alteration causes end-to-end security mechanisms to fail. We describe a proposal for a SIP end-to-end security mechanism between IPv4 networks and IPv6 stub domains, which overcomes the failure.
