Orientador: José Augusto Chaves Guimarães / Banca: Leilah Santiago Bufren / Banca: Ely Francina Tannuri de Oliveira / Resumo: Com o objetivo de caracterizar a produção científica docente da área de Tratamento Temático da Informação - T.T.I. foram selecionados 77 artigos de periódicos de autoria de 19 docentes de pós-graduação atuantes na área, buscando detectar as características dessa produção e das fontes de informação utilizadas pelos docentes-autores que possam oferecer um conhecimento mais amplo da área enquanto espaço de atuação acadêmica. Com os dados extraídos desses artigos, foi montada uma base de dados contendo os seguintes campos: autor, título do artigo, título da publicação, palavras-chave, citações, país, idioma e ano da publicação e instituição do autor. Para trabalhar os dados, foi utilizado o software VantagePoint que organiza a informação permitindo a geração de listas e matrizes de cruzamento de dados que possibilitam verificar os relacionamentos existentes entre os campos. Quanto à produtividade dos docentes autores, que estão distribuídos em 5 universidades (USP, UNESP, UFMG, UnB e UFF), a análise dos dados revelou que o conjunto manteve uma média de publicação de 4 a 5 artigos por ano, durante o período de 1990 a 2006. Esses artigos foram publicados em quatro idiomas - português, inglês, espanhol e francês - em 27 periódicos de 9 países, sendo 18 deles publicados no Brasil verificando-se, ainda, uma forte tendência a publicar em periódicos conceituados e de qualidade comprovada. Uma análise das 817 referências contidas nos artigos revelou um total de 659 autores citados e uma preferência pela utilização de livros como fonte de informação na ordem de 50%, assim como a predominância de autores clássicos da área como base teórica. Além disso, foi identificada uma presença em torno de 20% da produção do grupo de docentes na literatura utilizada na área, caracterizando o impacto e o valor da produção desses docentes para a área. / Abstract: Aiming at characterizing the scientific production of professors in the area of Subject Treatment of Information - S.T.I., 77 Journal articles by 19 post-graduation professors acting in the field, were selected, so as to detect the characteristics of this production and information sources utilized by authors- professors which may provide a wider knowledge of the area as an academic acting space. From the information provided by these articles, a database encompassing fields such as author, title of the article, title of publication, keywords, citations, country, language, year of publication and institution of the author, was compiled. The VantagePoint software, which organizes the information allowing the generation of lists and data-crossing matrices, which in turn enable one to verify the existing relationships among the fields, was used. As for the productivity of authors-professors who are distributed in 5 universities (USP, UNESP, UFMG, UnB and UFF), a data analysis showed that group kept an average of 4 to 5 articles per year, from 1990 to 2006. These articles were published in four languages - Portuguese, English, Spanish and France - in 27 Journals of 9 countries, being 18 published in Brazil and a strong trend to publish in renowned and high quality Journals was seen. An analysis of the 817 references contained in the articles, revealed a total of 659 authors cited and a 50% preference for books, as an information source, as well as the predominance of classical authors of the area, used as a theoretical base. In addition, some 20% of the professors' production in the literature used in the area, was identified, thus characterizing the impact and importance of this production for the field. The subjects approached were identified from the key-words utilized, demonstrating a predominance of interest for the processes of the area, being indexing the most frequent subject. / Mestre

abstract: Neural interfacing applications have advanced in complexity, with needs for increasingly high degrees of freedom in prosthetic device control, sharper discrimination in sensory percepts in bidirectional interfaces, and more precise localization of functional connectivity in the brain. As such, there is a growing need for reliable neurophysiological recordings at a fine spatial scale matching that of cortical columnar processing. Penetrating microelectrodes provide localization sufficient to isolate action potential (AP) waveforms, but often suffer from recorded signal deterioration linked to foreign body response. Micro-Electrocorticography (μECoG) surface electrodes elicit lower foreign body response and show greater chronic stability of recorded signals, though they typically lack the signal localization necessary to isolate individual APs. This dissertation validates the recording capacity of a novel, flexible, large area μECoG array with bilayer routing in a feline implant, and explores the ability of conventional μECoG arrays to detect features of neuronal activity in a very high frequency band associated with AP waveforms. Recordings from both layers of the flexible μECoG array showed frequency features typical of cortical local field potentials (LFP) and were shown to be stable in amplitude over time. Recordings from both layers also showed consistent, frequency-dependent modulation after induction of general anesthesia, with large increases in beta and gamma band and decreases in theta band observed over three experiments. Recordings from conventional μECoG arrays over human cortex showed robust modulation in a high frequency (250-2000 Hz) band upon production of spoken words. Modulation in this band was used to predict spoken words with over 90% accuracy. Basal Ganglia neuronal AP firing was also shown to significantly correlate with various cortical μECoG recordings in this frequency band. Results indicate that μECoG surface electrodes may detect high frequency neuronal activity potentially associated with AP firing, a source of information previously unutilized by these devices. / Dissertation/Thesis / Doctoral Dissertation Biomedical Engineering 2018

The thesis treats model reduction for linear time-varying systems. Time-varying models appear in many fields, including power systems, chemical engineering, aeronautics, and computational science. They can also be used for approximation of time-invariant nonlinear models. Model reduction is a topic that deals with simplification of complex models. This is important since it facilitates analysis and synthesis of controllers. The thesis consists of two parts. The first part provides an introduction to the topics of time-varying systems and model reduction. Here, notation, standard results, examples, and some results from the second part of the thesis are presented. The second part of the thesis consists of four papers. In the first paper, we study the balanced truncation method for linear time-varying state-space models. We derive error bounds for the simplified models. These bounds are generalizations of well-known time-invariant results, derived with other methods. In the second paper, we apply balanced truncation to a high-order model of a diesel exhaust catalyst. Furthermore, we discuss practical issues of balanced truncation and approximative discretization. In the third paper, we look at frequency-domain analysis of linear time-periodic impulse-response models. By decomposing the models into Taylor and Fourier series, we can analyze convergence properties of different truncated representations. In the fourth paper, we use the frequency-domain representation developed in the third paper, the harmonic transfer function, to generalize Bode's sensitivity integral. This result quantifies limitations for feedback control of linear time-periodic systems. / QC 20120206

Public policies in a pluralistic society should be able to clarify and cope with the complicated nature of public issues dominated by ¡§multiple parties, multiple values, and subjective judgment.¡¨ (Farkas & Anderson, 1974) Therefore, instead of merely concluding with the outcome, we should also take input into account when evaluating resource allocation or assessing policy effectiveness. In addition, since the public and the government differ in their judgment criteria and indicators, and multiple parties also have different understandings, the controversy of ¡§inequity¡¨ thus arises. In short, to conduct fairness measurement, we should focus on defining the parties as well as the input and outcome indicators. This research adopted the Public Affairs Management framework to analyze Cijin Seaside Park in Kaohsiung City and Tamshi Fishers¡¦ Wharf in New Taipei City. We have conducted a fairness measurement and cross-domain analysis to explore the equity perception in three aspects: economic equity, social fairness, and procedure justice. Moreover, we conducted a secondary data analysis, analyzed expert interviews, and generalized the carrier condition and factual judgment of the PAM framework. Furthermore, we explored the value judgment and interpersonal judgment in PAM framework with fairness measurement of the information integration theory. Our theory is based on the equity rule proposed by Anderson, which also emphasizes the individual and interpersonal comparison of individual input and outcome. Our results are demonstrated as follows: 1. In the individual value analysis of economic equity, both Cijin Seaside Park and Tamshi Fishers¡¦ Wharf have over 10 local stores and tourists that fits one-factor rule of the tourist number factor. 2. In the individual value analysis of social fairness, Cijin Seaside Park has 10 local stores that support one-factor rule of the public support factor. However, Cijin Seaside Park has over eight tourists that fit the adding rule of public support factor and actual request factor, whereas Tamshi Fishers¡¦ Wharf has over eight local stores and tourists that fit the same rule. 3. In individual value analysis of procedure justice, both Cijin Seaside Park and Tamshi Fishers¡¦ Wharf have over 14 local stores and tourists that fit the unequal-weight averaging rule of policy support factor and administrative cooperation factor. 4. In interpersonal comparison of economic equity, the experimental result shows that the local stores and tourists in both Cijin Seaside Park and Tamshi Fishers¡¦ Wharf fit the unequal-weight averaging rule of the integration of their tourist number factors. Also, the local stores and tourists in both Cijin Seaside Park and Tamshi Fishers¡¦ Wharf fit the unequal-weight averaging rule of the integration of their revenue (consumption) factors. Moreover, the local stores and tourists in both Cijin Seaside Park and Tamshi Fishers¡¦ Wharf both fit the adding rule of their respective tourist number factor and revenue (consumption) factor. This result also supports the ¡§rule of inequity integration.¡¨ 5. In interpersonal comparison of social fairness, the local stores in both Cijin Seaside Park and Tamshi Fishers¡¦ Wharf fit the unequal-weight averaging rule of the public support factor. They also fit the unequal-weight averaging rule of the actual request factor. As for the tourists, those in both two places fit the unequal-weight averaging rule of the public support factor. Also, they fit the unequal-weight averaging rule of the actual request factor. 6. In interpersonal comparison of procedure justice, the local stores in both Cijin Seaside Park and Tamshi Fishers¡¦ Wharf fit the unequal-weight averaging rule of policy support factor. They also fit the unequal-weight averaging rule of the administrative cooperation factor. As for the tourists, those in both Cijin Seaside Park and Tamshi Fishers¡¦ Wharf fit the unequal-weight averaging rule of policy support factor. Also, they fit the unequal-weight averaging rule of the administrative cooperation factor. We continued to conduct a cross-domain analysis to integrate the above research results, as well as the results of secondary data analysis and expert interviews. As a result, we thereby propose related suggestions and generalize the operation steps of fairness measurement.

This study investigates how the public forum cognition of citizen affect their intension to attend public forum given researching methods of Public Affairs Management Integrated Reference Framework (PAM) and Social Development Matrix(SDM). Based on PAM, we analysed the meaning of citizen governance and the role of citizen through real events, and discussed the cognition and psychological weights of our citizen to participate public forums. Through the analysis methods of literatures, this study summarized three factors that proposed by Ostrom(1990) - Institution, Commitment and Supervision, and then sequentially made the standard measurement divided into two levels by fair/unfair, high/low and valid/invalid. In this study, we focused on citizens who had participated in interactive management and chose Information Integration Theory (IIT) as our research method. Our research discussed that psychological weights of Institution, Commitment and Supervision, which defined three explanatory variables to estimate the public forum consciousness of citizens. By using SPSS and AVERAGE software, we computed the psychological weights of three factors and understood the attitudes of citizens toward public forum, furthermore, we compared the differences among the weights and offered suggestion and strategies of citizen governing in the future. The results are as following: 1. Compared to participants from traditional conservative society, our participants from highly developed multi-cultural society are more willing to attend public forums. 2. Participants of different backgrounds assess sequentially the importance of three factors by Supervision, Institution and Commitment. 3. Our results showed that the integrated information patterns(model) are all unequal weighted average pattern(model). 4. All three factors of our research are significant on dependent variable in main effects, two-factor interaction and three-factor interaction.

In the study, Cross-Domain analysis is used for ¡§Factual judgement, Value judgement and Interpersonal judgement.¡¨ The result of Factual judgement is made by the interviews of seven retired officers, scholars and experts. And it proceeds as ¡§true¡¨ judgement. Value judgement is indicated by in-depth intervuews with 3 representatives to obtain the ¡§good¡¨ judgement. Interpersonal judgement is based on overall strategies of the ¡§interactive management research group¡¨ and combines it with the perpectives of all patrties, as individuals and as groups, to conclude the ¡§beautiful¡¨ judgement. All the judgements are correspomded to the analysis of the analysis of the constitution, cognitive and conditions of the research topics. In order to have effective controls of all judgement factors, the interview topics are designed from the study of Mainland China1978 reform, and the rapid economic development, the double digit military spending, and the discussion of ¡§China threat theory¡¨, and the discussion by both sides leaders, academia to establish ¡§Military Confidence Building Measures (MCBMs)¡¨ in the PAM Framemork. The 10 steps of Cross-Domain analysis are used to clarify all studied objects and factors in order to obtain the recognition of experts. The practical policy suggestions are expected. Under PAM Framework, factual judgement perspective, majority of scholars and retired officers agree the necessary to establish ¡§Military Confidence Building Measures (MCBMs)¡¨. However due to the lack of political trust, time is not yet ripe. Retired officers suggest communication through media may solve the obstacles that impacted by the political environment in southern regions. Scholars have proposed that the southern people are affected by their own political inclinaitions, as well as the idea of their supported parties. From non-government exchange to government exchange, the recognition by people can be achieved by understanding the cultural difference and proceed to political and military trust. In vaule judgement, representatives realized the topic is involved in cross-strait relationship, political and military aspect and the uncertainty of policy. Therefore, they all took a more conservative point of view. However, they all agree that MCBMs should be based on the removal of missiles, and follow by the current policy ¡§economy first, political after¡¨ to establish non-government exchange. Due to state of hostility, it is recommended to start from oversea activities such as sea rescue and anti-piracy project. Work from political trust toward military trust. In interpersonal judgemant, a NGT and ISM two stages seminar is held by the ¡§interactive management research group¡¨. The participants voted through a weighted method to conclude 12 specific strategies to establish MCBMs. The strategies are summarized as follow: 1. Removed the missile targeting Taiwan from Mainland China to show the premise of MCBMs. 2. Provide National defense information for each party, to promote cross-strait arms information transparence, and eliminate ideological confrontation. 3. The establishment of cross-strait joint rescue mechanism. 4. The establishment of hotline for leader on both side. 5. The establishment of regular exchange visits of high level military decision makers on both sides. 6. The establishment of cross-strait military information interaction and communication platform. 7. The establishment of oversight system for MCBMs, such as supervised NGO consists of globally well-known and remarkable Cninese accepted by both sides. 8. From civil to government organization to held cross-strait military academic exchange and conference. 9. Showing grace by military budget and arm reduction. 10. Clarify the content of MCBMs. Develop cross-strait affairs negotiators. 11. Signing peace treaty to end hostile confrontation. 12.A nuclear, chemical and biological regulation treaty signed by both sides. In short, use the cross-domain analysis result to study the possibilities and challenges that might happen during the establishment of MCBMs. The following 5 recommendations can be used for future policy execution reference: 1. Strengthen the policy advocacy, public forums and policy discussion to enhance citizens¡¦ identity. 2. Strengthen cross-strait economic and cultural exchanges to relieve hostile condition. 3. Use ¡§1992 Consensus¡¨ as framework to establish political mutual trust. 4. Establish communication platform to eliminate speculations on both sides. 5. Deepen collaborative platform and signed a peace treaty.
