Fourteen word frequency metrics were tested to evaluate their effectiveness in identifying vocabulary in a domain. Fifteen domain engineering projects were examined to measure how closely the vocabularies selected by the fourteen word frequency metrics were to the vocabularies produced by domain engineers. Six filtering mechanisms were also evaluated to measure their impact on selecting proper vocabulary terms. The results of the experiment show that stemming and stop word removal do improve overlap scores and that term frequency is a valuable contributor to overlap. Variations on term frequency are not always significant improvers of overlap. / Master of Science

The purpose of this study is to develop experimental techniques to characterize typical interconnect discontinuities, including bends, steps, T junctions, vias and pads, which are the most commonly encountered interconnections in high speed digital integrated circuits, hybrid and monolithic microwave circuits and electronic packages. The time domain reflection response of these elements is used to classify the interconnect discontinuities as distributed discontinuity elements or as lumped elements depending upon the reflected waveform. For the cases of general distributed discontinuities including bends, steps and T junctions, the distributed equivalent circuit model is characterized by the time dependent impedance profile which is extracted from the time domain reflection measurements. By using known inverse scattering techniques implemented in terms of a new algorithm based on the transfer scattering matrix method of incremental uniform sections, this nonuniform impedance profile is extracted and is used to construct distributed element circuit models to represent the interconnect discontinuities. A circuit model consisting of lumped/distributed elements, is also developed for the interconnect discontinuities which is intended to combine the accuracy of the distributed model with the simulation efficiency of the lumped models. This hybrid mode reduces computer simulation time when used as a net list for general purpose circuit simulators, such as SPICE. For the case of discontinuities modelled as lumped elements, such as vias and wiring pads, closed form equations based on the transfer scattering matrix solution are derived and used to extract the lumped electrical parameters of these elements from the time domain reflection waveform. All of these lumped, distributed and hybrid models are validated by comparing the time domain simulation results with Time Domain Reflectrometer ( TDR ) measurements. A procedure for extracting the excess inductances and capacitances associated with the general discontinuities from the synthesized nonuniform impedance profile or the distributed model is also presented in this report. These results for excess lumped inductances and capacitances show close agreement with the published results for these structures which are based on the electromagnetic computation of excess currents and charges and frequency domain measurements. Finally, some typical cases demonstrating the effects of interconnect discontinuities in high speed clocking systems are presented and the procedure for reducing the reflections and transmission noise voltage by chamfering the bends and junctions is described. / Graduation date: 1992

Three students work in a team in this research. With the impact of cross-strait direct flights on Penghu as the theme, they start their discussions from the sub-themes which include the economy, the society and the government. The team carries out cross-domain analysis in these different fields, using research methods stretching from regional science, management science and policy science, among others. The team applies the different methods to different fields of study. Regardless of the limitation of the locations and the departments, PAM and the output of cross-domain analysis (analysis of the economic fundamentals, time series analysis, horizontal analysis, and gravity model) are used as the input of judgment analysis (Social Judgment Theory, or SJT). The output of regional analysis and judgment analysis are used as the input of policy analysis (Interactive Management, or IM). The above is combined with Penghu¡¦s existing historical information to yield independent, objective, and credible data for cross-domain analysis. Combining resources including the people, the time, the place and the event, the method encompasses different levels and the participants¡¦ cognitive psychology so that the various powers can come together before they are optimized; a consensus is reached and the maximum value shared by the public is created. This study can be very close related to the livelihood of the citizenry of Penghu. The Interactive Management, or IM, of the policy analysis is applied, combined with Nominal Group Technique, or NGT, and Interpretive Structural Modeling, or ISM, as the methods of analysis. Approximately 26 representatives from various fields are invited to participate. The NGT procedure, from the identification, clarification to voting on the issues, to the comparison among different issues are all assisted with the ISM software to generate an enhanced structural diagram that is more clearly structured and easy to read. After the participants¡¦ deliberation and revision, twelve strategies regarding ¡§the Impact of Cross-strait Direct Flights on Penghu¡Xfrom an Economic Point of View¡¨ were proposed. To clarify the enhanced connections among policies, to bring about an enhanced structural relationship, and to set forth the priorities, goals and directions for each policy, the participants believe that the first task is to establish an effective and integrated platform between the central and local governments, which will help the planning and enforcement of cross-strait policies, as well as improve other policies. Considering the above, government agencies should always bear in mind what the public wants. They should take the public¡¦s needs into consideration and care for the people to widely promote dialogue platforms as public forum so as to realize a ¡§bottom up¡¨ approach and to listen to the opinions from the root of the society. Efforts should be made by all parties to respond to the need of globalization. The public should pay attention to and examine public affairs in both the private and the public arenas. We should have our eyes on the whole and deal with the details. Public opinions should be fully developed, the society should be given more wealth, and the social conditions should be cultivated so that the civil spirits can take root, the power of the civil society can emerge, and a civil-governed democracy can be realized.

Three students work in a team in this study. With the impact of cross-strait direct flights on Penghu as the theme, they start their discussions from the sub-themes which include the economy, the society and the government. The team applies other theoretical frameworks in earnest exploration of Penghu¡¦s potentials to underline Penghu¡¦s readiness for its future. The team applies different method to different fields of study. Regardless of the limitation of the locations and the departments, PAM and the output of cross-domain analysis (analysis of the economic fundamentals, time series analysis, horizontal analysis, and gravity model) are used as the input of judgment analysis (Social Judgment Theory, or SJT). The output of cross-domain analysis and judgment analysis are used as the input of policy analysis (Interactive Management, or IM). The above is combined with Penghu¡¦s existing historical information to yield independent, objective, and credible data for cross-domain analysis. Combining resources including the people, the time, the place and the event, the method encompasses all levels and the participants¡¦ cognitive psychology so that the various powers can come together before they are optimized; a consensus is reached and the maximum value shared by the public is created. The IM theoretical framework is applied to this study, where the livelihood of the Penghu people and how to improve the living standard of the people are discussed. The public forum acts as the platform for dialogue. Twenty-four representatives from various fields were invited to express their ideas in a sensible discussion, where they take in others¡¦ opinions and learn from one another in a forum that is both theoretical and practical. The Interactive Management, or IM, of the policy analysis is applied, combined with Nominal Group Technique, or NGT, and Interpretive Structural Modeling, or ISM, as the methods of analysis. The NGT procedure, from the identification, clarification to voting on the issues, to the comparison among different issues are all assisted with the ISM software to generate an enhanced structural diagram that is more clearly structured and easy to read. After the participants¡¦ deliberation and revision, twelve strategies regarding ¡§the Impact of Cross-strait Direct Flights on Penghu¡Xfrom an Economic Point of View¡¨ were proposed. To clarify the enhanced connections among policies, to bring about an enhanced structural relationship, and to set forth the priorities, goals and directions for each policy, the participants believe that the first task is to deal with the waste management of the county, to raise the public¡¦s environmental awareness, and to solve water-and-electricity-related issues, which will improve other policies. IV The leaders should always start from the people, listen to the people, speak out for the people and keep the people in mind. Just like Atem Ramsundersingh, a senior official in the Water Department at the World Bank, pointed out: in the development of Taiwan¡¦s sustainable policies, the leaders should listen to the voice from the root of the society by allowing the ¡§bottom up¡¨ approach as an effective method for people to voice their opinions in a deliberative democracy. Considering the above and in the hope of identifying an appropriate alternate solution that is comprehensive, sound and practical as a reference for upcoming researchers, it is suggested that the policymakers, when discussing cross-strait policies, should listen to the opinions of people in Penghu via various channels. Practices should complement the theoretical framework in a research for it to reap greater results, namely, the fostering of civil awareness, the improvement of the levels of a civil society, and the realization of civil governance.

With Taiwan¡¦s economic development, and the wave of globalization as the impetus, after the government¡¦s ¡§No haste, be patient¡¨ policy and the mini-three links, on the first day of April, 2007, Penghu saw the launch of the conditional mini-three links. As the government gradually carries out cross-strait opening-up policies, the ¡§direct flight¡¨ is likely to arrive in the foreseeable future. As a response to the likelihood of the ¡§direct flight¡¨, what kind of impact and challenges will it bring to the Penghu economy? How should people in Penghu face up to them? What kind of opinions and suggestions should be made heard to the different levels in the government and the civil society? Dialogue mechanisms such as Denmark¡¦s Consensus Conference and the ¡§bottom up¡¨ method promoted by the World Bank of central Europe, as well as the US-borne ¡§Interactive Management¡¨, or IM, are approaches in which a small group of people gather in a small seminar to listen to one another¡¦s opinions and needs, and to negotiate in order to reach a consensus. These advanced and effective ways for people to come up with strategies all seeks wide participation from the people as their foundation, through a ¡§bottom up¡¨ dialogue, to generate practical and effective strategies. This research, based on the Public Affairs Management, or PAM, utilizes Nominal Group Technique, or NGT, and Interpretive Structural Modeling, or ISM, as a discussion method of interactive management. Three students work in a team. With the impact of cross-strait direct flights to Penghu as the theme, they start their discussions from the sub-themes which include the economy, the society and the government. The team carries out cross-domain analysis in these different fields, using research methods stretching from regional science, management science, and policy science, among others. The team applies different methods to different fields of study. Regardless of the limitation of the location and the departments, PAM and the output of regional analysis (analysis of the economic fundamentals, time series analysis, horizontal analysis, and gravity model) are used as the input of judgment analysis (Social Judgment Theory, or SJT). The output of regional analysis and judgment analysis are used as the input of policy analysis (Interactive Management, or IM). The above is combined with Penghu¡¦s existing historical information to yield independent, objective and credible data for cross-domain analysis, which is used by the discussion participants in sensible reasoning. The data are also internalized in the IM discussion platform to ensure the effectiveness of the participants, to distinguish among different groups, and to connect resources including the people, the time, the IV place and the event, so that the participants could engage in an effective dialogue on an equal footing provided by the discussion platform, where they study the impact of direct flights on Penghu¡¦s economy. After discussions and voting in two interactive seminars, the participants chose and proposed twelve strategies regarding ¡§the Impact of Direct Flights on Penghu¡Xfrom an Economic Point of View.¡¨ The cross-domain research method, encompassing different levels and the participants¡¦ cognitive psychology, engages the participants in sensible discussions so that the various powers can come together before they are optimized. This helps foster the formation of civil awareness and raise the levels of the civil society, contributing greatly to the goal of civil governance.
