This way, it becomes necessary to reduce the per capita consumption. From the actions that promote the racional use of water, the technological ones seems to be , in the most of the cases, the most recomended to reduce the consumption without being necessary radical changes of the users. One of these technologies is the rainwater harvesting. This one erges as an action of good perspectives since it subistitutes the use of potable water in activities where it is not necessary a good quality water, younder, it will reduce the amount of stormwater in the public drainage net, working as a non-structural action of urban drainage. The lack of kwondlege as well a the real advantages that a rainwater system can bring to a builind, is the points to find out about this issue.. At this paper, it seeked to clear this techonolgy up with the study of national and international examples . It also seeked the cistern sizing, getting the best results to technical and economical issues, as well, as procedures to design and to mantain the devices that make part of the system used in this study. Besides that, it studied the changes that would be necessary to build the system, and the possibles changes at the work routine of the construction company. It also studied the financial feasibility of the investiment of this interprisement, checking the real economical advantages that can be get. It is waited that this research contributes to the development of this techonology, contributing to Racional use of water in residential tall buildings.Item type:Item, Análise genética molecular (RAPD) de Conopophaga melanops, Vieillot 1818 (Aves, Conopophagidae), em escala fina da Mata Atlântica e sua implicação para a conservação da espécie(Universidade Federal de São Carlos, 2004-05-07) ;Lunardi, Vitor de Oliveira ;Galetti Júnior, Pedro Manoelhttps://lattes.cnpq.br/7398754661670478Conopophaga melanops is an endemic Atlantic forest bird species that had its habitat drastically fragmented by the historical process of massive deforestation. Today, its populations have survived isolated in small fragments and a few continuous forests, compromising the potential of the species to overcome natural and anthropic disturbances. The aim of this study was to estimate genetic differentiation among and within three populations of C. melanops in the major protected continuum of an Atlantic forest reminiscent using RAPD-PCR, to provide a better understanding of the geographical patterns of genetic variation of the species in fine scale and original context. The genetic molecular analyses showed a statistically significant genetic divergence among the three C. melanops populations in a continuum transect of 250 km. Primarily, this could be explained by the assumed sedentarism of the species and by the geographical barriers to gene flow. Pleistocene refuges and recent human impact could be adictional factors to explain the current genetic diferentiation.Item type:Item, Um framework para gerenciamento de qualidade de serviço em dispositivos móveis(Universidade Federal de São Carlos, 2004-05-10) ;Hobeika, Camillo Tannuri ;Zorzo, Sérgio Donizettihttps://lattes.cnpq.br/2523715806470871This work presents a Framework for Multimedia Applications with objective to make possible the use of these applications in Mobile Devices with limited computational capacity, considering the aspects of Quality of Service that can currently be used in these devices. The technological evolution cause a accented growth in the number of mobile device`s users, a time that the quality of the services also tends to increase, mainly as for the multimedia applications. Had to the characteristics of these devices and the nets where they operate, the traffic of multimedia information tends to increase the communication typical problems. However, parameters of Quality of Service (QoS) can be established and actions can be taken to try to diminish the impact of the inherent problems to the mobile computation in the multimedia applications. Thus, this work aims at the research and the development of one framework based on components for applications developed on the platform Java 2 Micro Edition (J2METM), of form to offer to greater quality in the multimedia communication for the mobile devices that possess limited resources.Item type:Item, Caracterização físico-química de PET ramificado e de suas blendas com PET reciclado(Universidade Federal de São Carlos, 2004-05-10) ;Prette, Lucas Del ;Zanin, Maria ;https://lattes.cnpq.br/9685965969782429https://lattes.cnpq.br/9897264455881060The growing concern with the solid residues management, observed in the last decade, due to its huge amount and impact, has motivated the search for recycling processes, where these residues can be reprocessed to generate new products, enlarging the cycle of materials and energy which are present in them. Special attention is given to the recycling of PET from containers of carbonated drinks. During the recycling of PET, the action of degradative fenomena creates a recycled resin with inferior properties, when compared to the original one, which difficults the use in new cycles of processing. The use of processing additives can overcome this effect. The improvement on the processability and modifications in the final properties of products made with blends of branched and linear resins have been reported in the literature. The branched resin could act as a processing additive. Even though some studies have characterized branched PET resins, the mixture of branched PET with recycled PET has not been reported before. Therefore, this study has as objective the characterization of a branched PET resin for use as processing additive in recycled PET and the characterization of the properties of the blends made with these two resins. In a first step, the characterization of the branched and recycled PET has been performed, and their properties compared with a bottle grade PET resin. The resins have been reprocessed to study the effect of the reprocessing over their properties. Modifications on the viscoelastic properties have been observed; the melt viscosity diminished, due to the degradation suffered during the process; the branched resin showed higher viscosity and melt strength. Next, the branched and recycled PET were blended. Improvements on the rheological properties were observed. The blends showed potential for use in transformation processes where higher melt strength is required.Item type:Item, Cuidado e educação nas atividades do berçário e suas implicações na atuação profissional para o desenvolvimento e inclusão da criança de 0 a 18 meses(Universidade Federal de São Carlos, 2004-05-11) ;Vitta, Fabiana Cristina Frigieri deEmmel, Maria Luisa GuillaumonThe insertion of children from 0 to 18 months old in children educational institutions, especially in groups like day care centers, has promoted several studies related to factors which involve such situation. Once one believes that these institutions will not only provide experiences that promote the child s interaction with other people but also encourage the development of the motor, perceptive and cognitive aspects, propitiating maturity so that the child can reach the autonomy and independence, one can have, in theory, a motivating view. Such phase can be considered the first one of the inclusive education. This study aims at analyzing the daily activities proposed to the day care center as a resource for the development of children from 0 to 18 months old. Documents on children education were studied. The practices of seven professionals who work at two day care centers which are linked to the Municipal Secretary of Education in Bauru were observed and interviews were realized. Such day care centers were chosen because they belong to the Secretary of Education mentioned above and are, thus, closer to fit the official documents which legislate for the children education. Such instruments focused the daily activities developed with the children. The data were organized according to analytic categories the day care center role, the conception of educating, taking care and playing, deficiency and inclusion and the daily activities organization were detailed. Such data were also analyzed according to the qualitative approach, allowing the confrontation between the empirical and theoretical material. The outcomes showed that the official documents do not discuss much about such phase, thus, the relationship between the daily activities and their role in the child s development is inaccurate. The care activities are prioritized and become part of the child s education, once, from the professionals viewpoint, they have a disciplinary role. In such context, the inclusion of children with special needs has some restrictions which express the preconceived ideas about deficiency. These outcomes are justified not only by the lack of knowledge about the child s development and the factors around it but also by the fact that they link their activities to their personal experiences. Taking the current practice into account, one should make efforts towards professional improvement so that they can understand their actions, attributing to them an educational intention.Item type:Item, A modernização tecnológica: seu patamar nos sistemas prediais hidráulicos e sanitários(Universidade Federal de São Carlos, 2004-05-11) ;Aro, Celso Ricardo ;Amorim, Simar Vieira dehttps://lattes.cnpq.br/8264867164852836Our country current socioeconomic environment is critical, with significant reduction in the construction industry consumer trade and great competition among this sector corporations which, to keep producing, are obliged to rethink their way to do so. Then, since the 80´s, these corporations have been questioning their technological delay and the low quality of their products, investing, afterwards, in the sector modernization. In this context, this research proposes a discussion about the adopted actions for sector technological modernization in order to rationalize and improve quality, as well as its technological level, emphasizing the Pumbling Systems. To do so, bibliographies related to the subject have been consulted to get familiar to the problem and possible ways to face the question and, in a later moment, verify it using cases of study. A field research was held in medium and small construction corporations in Ribeirão Preto. It was structured with visits to the buildings, where items related to the problems were verified through a Check-list and, later, analyzed to determine the corporation technological level related to the Pumbling Systems. In this research, it was evidenced the construction corporation unconcern related to the Pumbling Systems and its less importance compared to another sub-systems, such as architecture and structures. The technological level found in these corporations brings out the evidence of management investment necessity, creation of standard procedures and evaluation and selection criterion of the work. Only after consolidating these questions, the introduction of technological innovations will achieve their purposes.Item type:Item, Estudo de estruturas, interações e reconhecimento molecular em carboidratos utilizando simulação computacional(Universidade Federal de São Carlos, 2004-05-11) ;Pereira, Cristina Saldanha ;Freitas, Luiz Carlos Gomidehttps://lattes.cnpq.br/3461414255262928In this work, computer simulation methods were applied to investigate glucose-derived carbohydrates in solution at atomistic resolution. The carbohydrates considered were: trehalose and cyclodextrins. The disaccharide trehalose is well known for its bioprotective properties. Produced in large amounts in organisms able to survive extremely damaging conditions trehalose plays its protective role by stabilizing biostructures such as proteins and lipid membranes. In the present study, molecular-dynamics simulations were used to investigate the interaction of trehalose with a protein and a membrane. To investigate the interaction trehalose-protein molecular-dynamics simulations of the protein lysozyme in solution have been carried out in the presence and in the absence of trehalose at room temperature. The results show that the trehalose molecules cluster and move towards the protein, but do neither completely expel water from its surface, nor form hydrogen bonds. Furthermore, the coating by trehalose does not significantly reduce the conformational fluctuations of the protein. The interaction trehalose-membrane was investigated performing simulations of a lipid bilayer in the absence and in the presence of trehalose at two different concentrations and temperatures. The results show that trehalose is able to minimize the disruptive effect of elevated temperature and stabilize the bilayer structure. Trehalose is found to interact directly with the bilayer through hydrogen bonds. However, the water molecules at the bilayer surface are not completely replaced. At high temperature the protective effect of trehalose is correlated with an increase in the number of hydrogen bonds with the bilayer and of trehalose molecules bridging three or more lipid molecules. Cyclodextrins are cyclic oligosaccharides presenting a cavity able to accommodate and modify the properties of a huge variety of molecules. Their structural behavior in solution is determinant for the complexation abilities. Molecular dynamics simulations have been performed in solution for the three natural (α, β and γ) cyclodextrins at room temperature. Results show that the conformational flexibility in solution is mainly defined by variations in the ring backbone of these molecules. Interglucose secondary hydrogen bonds are present in solution and show a very dynamical character, where alternative hydrogen bonds to water molecules are present. Water molecules were found to exist inside the cavities and present residence times in this region that is dependent on the size of the cyclodextrin molecule.Item type:Item, Consumo e influência de exopolissacarideos de Anabaena spiroides (Cyanophyceae) sobre a toxicidade e captura do cobre por Ceriodaphnia cornuta (Cladocera, Daphnidae)(Universidade Federal de São Carlos, 2004-05-13) ;Choueri, Rodrigo Brasil ;Melão, Maria da Graça Gamahttps://lattes.cnpq.br/8342306603661310Human specie can alter deeply and very fast the enviroment in which it is in. Because of the industrial development, the water, air and soil contamination have become cause of concern, chiefly in big cities with great populations. Among the contaminants figure the heavy metals, which levels at aquatic and terrestrial ecossistems are growin up every year. These elements are able to bioaccumulate in the organisms and biomagnified on the food webs. The bioavailability of metals can be influencied by several factors like the complexation with dissolved organic matter, e.g. algal exudates, that generally decreases the toxicity of this elements. The scope of this work was evaluate the potencial use of exopolysccharides of Anabaena spiroides (Cyanophyceae) as food source of Ceriodaphnia cornuta (Cladocera, Daphnidae), and to establish the influence of this organic matter on copper toxicity and uptake to this cladoceran. Initially, it was estabilished the C. cornuta length-weigth relation. After this, it was investigated ingestion of exopolysccharide and its influence in life history parameters of C. cornuta. Results showed that A. spiroides exopolysccharide is able to sustain a population of this zooplanktonic specie. Individuals fed with this compound exhibited rate of population growth very significant to this specie (r = 0,263). The copper acute toxicity and uptake by C. cornuta assay revealed that addition of 30mg L-1 of A. spiroides exopolysccharide increased about 4 times copper EC/50 (calculated by Trimmed Spearman-Karber method) to C. Cornuta (from 8,11x10-8M ±9,80x10-9M without exopolysccharide to 3,25x10-7M ±5,30x10-8M with addition of exopolysccharide). Copper concentration in the organisms after 24 hours exposure to several metal concentration was determined by DPASV using a polarograph and showed little variation among concentrations and treatments with and without exopolysccharide. It suggests that organisms of this study were able to regulate copper body contents.Item type:Item, Desenvolvimento de instrumentos e procedimentos analíticos automáticos com detecção quimiluminescente e espectrofotométrica(Universidade Federal de São Carlos, 2004-05-14) ;Borges, Eduardo Poggi e ;Reis, Boaventura Freire doshttps://lattes.cnpq.br/7619359855870896In the present work is described computer-controlled flow systems designed for process control of L-alanine synthesis and for bromide determination in this amino acid, presented as a contaminant species. Since the analytical systems were computer controlled, all the procedures steps, such as, stopped flow, dilution, pH adjustment, analyte concentration and sample clean up, were performed without operator assistance. In order to carry out chemiluminescent reaction, a simple and low cost device (ca. US$ 150) that comprises two photodiodes fixed in lab-made Perspex flow cell was proposed. Regarding L-alanina determination, it was exploited the L-amino acid oxidize enzyme reaction. In this system, the sample was injected into a carrier stream, passing through a column packed with this immobilized enzyme. The product of the amino acid oxidation, hydrogen peroxide, was determined by the chemiluminescent reaction with luminol. The interfering species of the enzymatic reaction was suppressed by coupling in the flow system a column packed with a strong anionic resin. A linear concentration range between 0.5 and 25 mmol L-1 and a 0.08 mmol L-1limit of detection were some of the analytical characteristics of this system. Regarding the chemiluminescent bromide determination, the procedure was based on bromide oxidation by chloramine-T followed by the reaction of the formed bromine with luminol. In order to minimize the interference of alanina in the chemiluminescent reaction, a column packed with a strong anionic resin was used for analyte concentration and sample clean up. The analytical features obtained were a linear range between 0.010 and 1.000 mg L-1 (r=0.999) and a limit of detection of 1 µg L-1 of Br-. Also in this work is reported the development and the characterization of a lowcost device for NO2 determination in atmosphere exploiting the Griess-Slatzman reaction. The NO2 was sampled from the atmosphere by a porous membrane tube, which was also used as flow cell. To monitor the colored-forming reaction, it was constructed a dual-wavelength LED-based spectrophotometer. With the proposed device it was obtained a 0.5 ppbv limit of detection of NO2, a low reagent consumption (100 µL per determination), 5 % relative standard deviation for 5 ppbv NO2 sample concentration and long term stability, at least 168 hours without requiring calibration procedure.Item type:Item, Processo de planejamento de reengenharia guiado por avaliação de usabilidade(Universidade Federal de São Carlos, 2004-05-14) ;Discola Junior, Sérgio Luisir ;Silva, Junia Coutinho Anacletohttps://lattes.cnpq.br/6200743168568684Software can be modified since its creation, deployment and maintenace. Many are the reasons for that: missing requirements, misunderstood requirements, bugs, among others. But, there is one strong reason that should be studied: the missing of usability. Many companies, like Nokia and Oracle detected usability as the major reason for the software modification. Software modification can be done using many techniquies: substitution, maintenance or reengineering. The last consists the revitalization of the software project, its modification and implementation. For that, a criterious planning should be done so as this research goal is to establish a Reengineering Planning Process Guided by Usability Evaluation. This planning should be able to evaluuate the usability of the software and turn reengineering guided by this evaluation so as the produced software turns easy to use, learn and make the user satisfied.Item type:Item, Meta-modelo para o processo de sistemas com RV pautado por enfoque no usuário, iteratividade de projeto e critérios de usabilidade(Universidade Federal de São Carlos, 2004-05-17) ;Olher, Milena Marquezin ;Silva, Junia Coutinho Anacletohttps://lattes.cnpq.br/6200743168568684The continuous growth of the Human-Computer Interaction area has been causing the appearance of approaches to better correspond to the users' needs, concerning not only the functionality factors of the interactive systems, which are the main focus of the Software Engineering area, but also the interaction factors of those systems. In that context, the Virtual Reality technology comes as a change proposal for the development of more advanced interfaces, with regard to the human-computer interaction, offering means of interaction that are more natural to humans to supply to the interactive system users' expectations by a more natural and intuitive interaction, as well as involving resources and studies in the most several fields of the knowledge. In that way, although it has evolved significantly, its usage in interactive systems still presents challenges to overcome, among which a better analysis and formalization of the process of systems with Virtual Reality in the practices of the Human-Computer Interaction and Software Engineering areas. However, researches that detail the process of systems with Virtual Reality so that its benefits are explored are little found in the literature. This work proposes a meta-model for the process of systems with Virtual Reality, identifying the differential of those systems and the existing implications in your process, presenting and critically analyzing the methodologies mentioned in the literature for the process of systems with Virtual Reality, as well as identifying the process models in Software Engineering and the approaches in Human-Computer Interaction that best assist the identified implications in the process of those systems, which focus on the user, project iteration and usability.Item type:Item, Macunaíma trágico: a modernização brasileira em Mário de Andrade(Universidade Federal de São Carlos, 2004-05-18) ;Manieri, DagmarVilla, Marco AntonioItem type:Item, Mineração de dados em múltiplas tabelas fato de um data warehouse(Universidade Federal de São Carlos, 2004-05-19) ;Ribeiro, Marcela Xavier ;Vieira, Marina Teresa Pireshttps://lattes.cnpq.br/5446518523049572The progress of the information technology has allowed huge amount of data to be stored. Those data, when submitted to a process of knowledge discovery, can bring interesting results. Data warehouses are repositories of high quality data. A procedure that has been adopted in big companies is the joint use of data warehouse and data mining technologies, where the process of knowledge discovery takes advantage over the high quality of the warehouse s data. When the data warehouse has information about more than one subject, it also has more than one fact table. The joint analysis of multiple fact tables can bring interesting knowledge as, for instance, the relationship between purchases and sales in a company. This research presents a technique to mine data from multiple fact tables of a data warehouse, which is a new kind of association rule mining.Item type:Item, Ergonomia dos ônibus urbanos: estudo de caso na cidade de Santos(Universidade Federal de São Carlos, 2004-05-20) ;Santos, Alda Paulina dos ;Sanches, Suely da Penhahttps://lattes.cnpq.br/3857424839674606In Santos SP, a survey was carried out among bus users, regarding these aspects, with the purpose of supplying parameters for the improvement of quality, safety and comfort for those who use public transports by bus. As public transport is the most important way of transportation, daily used by most of people, it is very important to analyze the characteristics of urban buses under the ergonomic point of view to get an important improvement of the user s quality of living. Starting from the analysis of internal internal items of chosen vehicles, such as furniture and layout, and the opinion research made among users, statistical tests were done to get conclusions and suggestions for the improvement of buses quality. Through the opinion research was possible to know better the profile of urban bus users and it concludes that despite of analyzed vehicles fulfill the requirements and regullations, many items don t answer the needs of passengers comfort.Item type:Item, Avaliação de procedimentos para preparo de amostras agronômicas visando determinação multielementar por espectrometria de emissão ótica com plasma induzido(Universidade Federal de São Carlos, 2004-05-21) ;Silva, Fernando Vitorino da ;Nogueira, Ana Rita de Araújohttps://lattes.cnpq.br/7034773971317045Sample preparation was always considered a limiting factor for sample throughput in the analytical sequence due to its high time consumption and great probability for error insertion in the results. Therefore, purposes to generate lower analysis time and, mainly, to make sample handling a feasible process are readily wished. Two procedures for preparation of agricultural samples (bovine milk and fruit juices) for multielemental determination by inductively coupled plasma optical emission spectrometry have been investigated. A procedure for bovine milk treatment based on use of proteolytic enzymes (pepsin) and protein precipitator agent (trichloroacetic acid) for extraction of Ca, Fe, Mg, and Zn was investigated. Application of these reagents allowed to check the complex interaction between Fe and milk proteins. Quantitative determinations from simple protein precipitation in solution showed good results for Ca, Mg, and Zn. Results obtained for Fe, using protein precipitation, confirmed the strong bound of this element with the casein micelle. In general, the recovery of Fe on protein precipitate was around 100 %. Taking into account the procedure for fruit juices treatment, a flow system operating at high temperature and high pressure was developed. This system presented decomposition efficiency around 99 % for different carbon sources when 300 oC and 60 bar was applied. As result, it can be suggested that the use of diluted nitric acid (HNO3 1.4 mol L-1) associated to hydrogen peroxide as auxiliary oxidant agent (H2O2 3.0 % v v-1), does not compromise the decomposition efficiency if high temperature is applied. Recoveries of Ca, K, Mg, and Na in the digestates obtained by the flow system were in agreement with those found in the closed vessel-MW assisted acid decomposition. The flow system behavior for vegetal tissues slurries decomposition was also evaluated. At the same time the spectrometers performance was evaluated. Figures of merit, warm up time, long and short term stability, spectral resolution, and limit of detection were compared for axially- and radially-viewed configurations. The performed experiments showed similar performance for both configurations, differing only on the warm up time and limit of detection. Taking into account the obtained results it is possible to infer that most of the applications performed with the radially-viewed configuration could be carried out in axially-viewed ICP OES s with no analytical performance degradation.Item type:Item, Computação ciente de contexto aplicada ao monitoramento de condições críticas em ambientes físicos(Universidade Federal de São Carlos, 2004-05-21) ;Kudo, Taciana Novo ;Araujo, Regina Borges dehttps://lattes.cnpq.br/8964123297688432Context-aware computing investigates applications that adapt their behavior according to information (or context) captured from a physical and/or computational environment such as the location of a user. The monitoring of critical conditions in physical environments is one of the domains that take advantage of the context-aware computing facilities, where context is captured from sensors spread over environments in order to aid the prevention, the combat and the evaluation of emergency situations such as fire, rebellions in penitentiaries, explosions and leaks of toxic substances. Related works report the need for a middleware that provides services, e.g. for context interpretation and location of people and objects, which can be used by a myriad of devices and any kind of applications for monitoring of critical conditions, regardless platform, operating system and/or programming language. This work presents an approach exploiting context-aware computing in the monitoring of critical conditions in physical environments, which includes the specification of a middleware and its following main services: the Context Interpreter Service, the Event Notification Service and the Location Service. The Context Interpreter Service notifies and interprets context gathered from sensors. As those interpretations follow the security policies of each business, an Interface for Configuration and Monitoring was also developed as a means to allow particular criteria of monitoring for a business. The Event Notification Service uses the publish/subscribe paradigm based on topics. The Location Service handles the location of people and objects in physical environments. Middleware components and applications communicate through XML-encoded messages via publish/subscribe mechanism. A case study for that approach uses the Asas de um Sonho aviation museum of the TAM air company as scenario.Item type:Item, Abordagem aspecting: migração de sistemas OO para sistemas OA(Universidade Federal de São Carlos, 2004-05-21) ;Ramos, Ricardo Argenton ;Penteado, Rosângela Aparecida Dellossohttps://lattes.cnpq.br/4061946080136286An approach, named Aspecting, is proposed for eliciting aspects in Object Oriented systems and subsequently re-factoring these systems as aspect oriented systems. The approach has three phases: Understand the System Functionality, Treat the Interests and Compare the Object Oriented System with the Aspect Oriented System. Each phase is presented with the details to be observed by the software engineer for the migration of the systems to be made safely and to obtain a quality product. Techniques of separation of concerns and aspect oriented programming are used in three prospective study cases, in order to induce formulating the approach. Guidelines are established to model the concerns identified, using class diagrams in UML notation. Other guidelines govern the implementation of concerns as aspects, using the Aspect J language. The use of regression tests in the system after the system code reorganization now implemented with aspects, for checking if the original functionality has been preserved in the migration, completes the approach. A fourth study case, for illustrating the approach application, is also presented.Item type:Item, Um paradigma baseado em algoritmos genéticos para o aprendizado de regras Fuzzy(Universidade Federal de São Carlos, 2004-05-24) ;Castro, Pablo Alberto Dalbem de ;Camargo, Heloisa de Arruda ;https://lattes.cnpq.br/0487231065057783https://lattes.cnpq.br/1863177057291007The construction of the knowledge base of fuzzy systems has been beneficited intensively from automatic methods that extract the necessary knowledge from data sets which represent examples of the problem. The evolutionary computation, especially genetic algorithms, has been the focus of a great number of researches that deal with the problem of automatic generation of knowledge bases as search and optimization processes using di erent approaches. This work presents a methodology to learn fuzzy rule bases from examples by means of Genetic Algorithms using the Pittsburgh approach. The methodology is composed of 2 stages. The first one is the genetic learning of rule base and the other one is the genetic optimization of the rule base previously obtained in order to exclude redundant and unnecessary rules. The first stage uses a Self Adaptive Genetic Algorithm, that changes dynamically the crossover and mutation rates ensuring genetic diversity and avoiding the premature convergence. The membership functions are defined previously by the fuzzy clustering algorithm FC-Means and remain fixed during all learning process. The application domain is multidimensional pattern classification, where the attributes and, sometimes, the class are fuzzy, so they are represented by linguistic values. The proposed methodology performance is evaluated by computational simulations on some real-world pattern classification problems. The tests focused the accuracy of generated fuzzy rules in di erent situations. The dynamic change of algorithm parameters showed that better results can be obtained and the use of don t care conditions allowed to generate a small number of comprehensible and compact rules.Item type:Item, Cursos de formação inicial de professores de química: uma análise das manifestações de professores da Diretoria Regional de Ensino de São Carlos.(Universidade Federal de São Carlos, 2004-05-25) ;Brito, Dorval dos SantosHartwing, Dácio RodneyThe purpose of this research work was to analyse and discuss the thematic of the formation of teachers, making references to the contributions of the course of licenciateship in Chemistry for professional learning, throught the survey and analysis of the information showed by acting licensed teachers in Chemistry from the teaching Regional Board of Directors from of São Carlos-SP. For the accomplishment of the research work we started from data collected by means of a frameworked questionnaire in two blocks: one corresponding to a personal data/professional formation (academic) with seventeen questions and another about data from the professional acting formation course with thirty-three questions, the composition of the questionnaire was made most of open questions and some closed ones. The questionnaire was answered by twenty-five acting licensed teachers in Chemistry, on which, we would collect the opinion of those teachers about some aspects of his/her process of formation and professional performance, that is, aspects referring to the curriculum, the evaluation, the didactic/methodological procedures, a new standard formation of (practice-reflexive) teachers, the difficulties and facilities found as a professional, as well as his/her professional performance. In the treatment of the collected data, we proceeded to a qualitative analysis of the answers of the questionnaires through, the description of information obsained from acting licensed teachers in Chemistry, we considered the information with similar meanings, configuring in classes of quantified answers in frequencies and percentages. According to the conclusions , it was clear that new ways must be investigated in the formation of teachers. In spite of acting Chemistry teachers having presented relevant and important aspects, they also pointed out some problems and difficulties of critical form in relation to his/her formation from the licensed teacher in Chemistry. For being a research work with qualitative nature, the conclusions can not be generalized, but they can be used in the understanding of similar situations that could occur in the other contexts.Item type:Item, Canais de Santos: trajetória do tombamento de uma identidade urbana(Universidade Federal de São Carlos, 2004-05-25) ;Ramos, Dawerson da Paixão ;Silva, Ricardo Siloto dahttps://lattes.cnpq.br/5346985934880710The aim of this assignment is to understand the involvement between the city and its inhabitants, as well as the planning tools capable of exposing its behaviour towards the dynamics which build up the urban area and the elements which determine its identity. Specifically considering Santos, the object is found in the canals which are part of the drainage system projected by the sanitation engineer Saturnino de Brito. In the historical process, which has determined this base element of the urban area as well as the city identity, it s possible to find the reasons for preserving the historical, architectural, artistic and cultural heritage, being this the scenery for proposing the analysis of the social mobilisation in favour of its preservation, in order to prove our hypothesis, taking into account the community participation which allows, at times, that the cultural dynamics superimpose the economical dynamics when building the urban area.
