Item type:Item, Modelagem da demanda de água de abastecimento para a cidade de Pirassununga - SP(Universidade Federal de São Carlos, 2005-05-05) ;Silva, João Batista da ;Barbassa, Ademir Pacelihttps://lattes.cnpq.br/2979012440240781Because it is a natural resource that is vital to animal and vegetable life, and considered a temporary resource, water must be used with responsibility, aiming at its protection and preservation so there is no lack of it in the near future. There are several factors that contribute to the scarcity of water, ranging from the lack of a conservationist policy to the lack of consumer awareness. Predicting the average water consumption based on historic data is an important tool to be used in the planning, in the estimate of the consumption and in the direction of the sanitation management. The objective of this work is to analyze and model the data on the urban water consumption in the city of Pirassununga, State of São Paulo, from 1993 to 2002. The explanatory variables used were: the number of inhabitants per connection, the marginal water price, the ‘per capita’ income per household (replaced by the next added value), the temperature, the precipitation and the relative humidity of the air. The method of consumption per connection, the method by unitary coefficient and the linear model of multiples coefficients were applied after the treatment and graphic analysis of the data. Although there was an increase of the total consumption of water, the consumption per connection presented a drop. The model that best explained the consumption function was that of multiple coefficients. Most of the explanatory variables used were significant and their coefficient signs were also the ones expected.Item type:Item, Estudos moleculares da Selenocisteína Sintase (SELA) de Escherichia coli(Universidade Federal de São Carlos, 2005-05-05) ;Cassago, Alexandre ;Thiemann, Otávio Henriquehttps://lattes.cnpq.br/4933022274560322The study of translation processes attracts the interest of a wide range of research groups due to its main role in general cellular metabolism. In particular, the investigation of new amino acid residues, such as selenocysteine and pyrrolysin, which result in an expansion of the genetic code from the traditional 20 residues to a total of 22 residues up to the current time. The amino acid, selenocysteine represents the main biological form of the selenium element and its synthesis and co-translational incorporation into selenoproteins are due to an in-frame UGA stop codon using complex molecular machinery. On Escherichia coli, the main proteins involved in this pathway are: Selenocysteine Synthase (SELA), Selenocysteine Elongation Factor (SELB or EFSec), Selenophosphate Synthetase (SELD) and a tRNAsec uca specific for this pathway named Selenocysteine Insertion tRNA (SELC). The SELA protein, the subject of this study, was firstly purified by Forchhammer in 1991 and the sole structural analysis realized to this day was developed by Engelhardt in 1992, using the Scanning Transmission Electron Microscope (STEM) technique. With a monomer of approximately 50kDa, SELA assumes an homodecamerical spatial configuration, each dimmer capable of binding to a tRNAsec uca with the serine amino acid which will be converted in selenocysteine, in a reaction dependant of the enzymatic cofactor piridoxal 5 fosfato. On this work it was possible to develop a new purification protocol for the SELA protein, considerably reducing the steps and consequently the time involved for obtaining purified protein. The process also yielded better protein production when compared to literature, from 1mg/ml starting with 10 liters to approximately 4.5mg/ml starting with 3 liters of bacterial medium. As for the structural experiments, it was possible to predict by Dynamic Light Scattering (DLS) the molecular mass as about 442kDa, Circular Dichroism (CD) predicted the secondary structure as mainly composed by α-helices and Small Angle X-ray Scattering (SAXS) showed the global structure of SELA with a maximum diameter of 185Å, a molecular mass of about 527kDa and a radius of gyration of 67.3 ÅItem type:Item, Material particulado atmosférico na cidade de São Carlos- SP: quantificação e identificação de fontes(Universidade Federal de São Carlos, 2005-05-05) ;Bruno, Ricardo Luiz ;Coury, José Renatohttps://lattes.cnpq.br/3711547435042712In the present work, breathable particulate matter (PM10) concentration was measured in their fine (PM2.5-10) and ultra-fine (MP2.5) fractions, in the municipal district of São Carlos. The samplings were carried out from 2001 to 2004 for PM10 (complemented with data from 1997 to 2001 taken from the research group databank) and for the period of 1 year (2001-2002) for PM2.5. PM10 was sampled with a high volumes sampler, while PM2.5 and PM2.5-10 were sampled with a dichotomous sampler. In order rationalize the seasonal variation MP, the year was separated in two different periods, the so-called dry period characterized by colder months and smaller incidence of rains and the rainy period, characterized by hotter months and by larger incidence of rains. After the collection, XRF analysis were carried out to quantify the chemical elements with mass molar superior to 12 a.m.u.. Also, DIC/DOC (dissolved organic and inorganic carbon) analysis were performed. The results showed 14 chemical elements, on average, both in fne and ultrafine fractions. The chemical elements that appear in larger concentrations in the PM are organic carbon, inorganic carbon, Al, Si, Ca, Ti, K, S and Fe. Two receptor models, the principal factors analysis (PFA) and chemical mass balance (CMB) were used to quantify the probable pollution sources for responsible for the sampled PM in the receptor site. PFA suggests that 3 main sources are responsible for the PM in the ultrafine fraction, both in the dry as well as in the rainy season. As for the fine fraction, the PFA suggests that 4 main sources are responsible for the pollution in the receptor site. The CMB analysis indicates that, for the ultrafine fraction the main source is the gas/particle conversion from sulfur, both in the dry and rainy periods. For the dry period, the biomass burning becomes significant as a pollution source. In the fine fraction of MP, the main sources identified were soil resuspension and vehicular emission.Item type:Item, Determinação da carga eletrostática em aerossóis e seu efeito na filtração de gases(Universidade Federal de São Carlos, 2005-05-06) ;Rodrigues, Marcos ViníciusCoury, José RenatoIt has been shown that the presence of electrostatic charges in particles affects significantly the performance of a filter, both increasing collection efficiency and reducing pressure drop. The aim of the present work is to verify the influence of the charge level on collection efficiency during the first stages of filtration. A charge classifier was used to measure the charge level of the aerosol as a function of particle diameter. The filtration unit was made of polypropylene with 600 g/m2 weighing, and had a diameter of 0.047 m and a thickness of 0.0026 m. The solid used was a phosphate rock (density 2940 kg/m3 and average Stokes diameter of 3.40 mm). The aerosol was dispersed by a TSI Venturi type generator, model SSPD 3433. The particle charging was achieved by a corona. In all the tests a linear relation between the particles acquired charge and their diameter was observed. A gradual increase of the charge level was observed with an increase of the tension in the corona charger (0, -3, -6 kV). The filtration results indicated that the global collection efficiency of the filter was very sensitive to the variation of the charge level of the particles. Both efficiency and pressure drop increased when the charge level increased. During the tests, the small increase in pressure drop was evidence that the cake had not yet been formed.Item type:Item, Reforma autotérmica do metano: estudo do Processo e de catalisadores(Universidade Federal de São Carlos, 2005-05-07) ;Dias, Joelmir Augusto Costa ;Assaf, José Mansur ;https://lattes.cnpq.br/9563312407691130 ;https://lattes.cnpq.br/8994385933947902https://orcid.org/0009-0000-5458-7765The study of the autothermal reforming of methane over Ni/γ-Al2O3 catalyst, promoted with noble metals was the objective of this work. In the first part, the stability to coke deposition of the autothermal reforming was studied, through air addition to the feed of steam reforming, at 600oC over Ni/γ-Al2O3, at favourable conditions to coke deposition (CH4/H2O=4). It has been observed that the amount of coke decreased with the increase in air addition. This leads to the conclusion that the autothermal reforming of methane is a stable process to coke deposition. The second part of the work concentrated in the understanding of the effect of small amount (0,3% w/w) of the noble metals platinum, iridium and palladium for the steam reforming, partial oxidation and autothermal reforming of methane. The preparation of the platinum- and iridium-promoted catalysts was made via chloride. For the palladium, chloride and nitrate was used. It has been observed that the addition of noble metals allowed the reduction of the catalyst at lower temperature, increasing the reduction degree and, consequently, the metallic surface area of the catalyst. The small amount of noble metals did not cause any important electronic influence to nickel. Partial oxidation of methane also did not suffer any effect of noble metals, given that the non-promoted catalyst took this reaction to thermodynamic equilibrium. The steam reforming hat its conversion increased, and this increase was proportional to the metallic surface area. The same happened with autothermal reforming. This leads to the suggestion that the steam reforming is the limiting step for the autothermal reforming. Thus, it has been concluded that the unique important effect of the addition of platinum, iridium and palladium to the Ni/γ-Al2O3 catalyst, for autothermal reforming, is the increase in metallic surface area of the catalysts. The same catalysts were submitted to start tests of autothermal reforming of methane, without previous reduction with hydrogen. These tests were made through intermittent starts at 600oC, alternated with air flow at high temperature. The platinum- and iridium- promoted catalysts were active in all starts. For the catalysts promoted with palladium, only the ones prepared via nitrate was active. The palladium-promoted catalysts, via chloride, did not showed activity in autothermal reforming without previous reduction with hydrogen, being active only for combustion of methane, due to the non-reduction, due to the formation of palladium oxochloride, which has a strong interaction with alumina. In the third part of the work, the behavior of the steam and autothermal reforming and partial oxidation of methane in extended bed reactor was studied. The temperature profiles of the reactions were measured with the catalysts promoted with platinum and palladium. It has been verified that the partial oxidation and autothermal reforming occurs via combustion, parallel with steam and CO2-reforming. The promoted catalysts showed a flatter temperature profile than non-promoted catalyst, due to the difference of activity among them.Item type:Item, Mar de cana, deserto verde? Dilemas do desenvolvimento sustentável na produção canavieira paulista.(Universidade Federal de São Carlos, 2005-05-10) ;Gonçalves, Daniel Bertoli ;Alves, Francisco José da Costahttps://lattes.cnpq.br/9183120186518337The role of the sugar-cane production in the regional sustainable development has been lifting a lot of controversy on those last years. While the Brazilian sugar-cane sector is prominence in the international market, offering products of great value in terms of environmental sustainability, the workers and the local communities that live together with the sugar-cane production system alleges another reality, marked by the unemployment, bad field work conditions, environmental pollution, and bad distribution of income. This work makes an analysis about the social and environmental situation of the sugar-cane production in the sugar-cane area of the Hydrographic Basin of the river Mogi-Guaçú, main sugar-cane area of the State of Sao Paulo, identifying the main obstacles that this activity presents for the sustainable development, and the proposals and alternatives that exist for the improvement of the environmental and social conditions of this activity in the area. The analysis shows that the situation of environmental and social unsustainability in that meets the regional sugar-cane production system it will only be able to be solved through the consolidation of a regulatory endowment built by the group of the local society.Item type:Item, O sentimento do mundo: o corpo na poesia de Carlos Drummond de Andrade.(Universidade Federal de São Carlos, 2005-05-10) ;Perius, Cristiano ;Ferraz Neto, Bento Prado de Almeidahttps://lattes.cnpq.br/0084436724293824Ce travail constitue une tentative de lecture du mouvement « phénoménologique » de la poésie de Carlos Drummond de Andrade. Ce mouvement sous-entend le temps historique, tout d´abord, mais surtout l´opération que transforme les choses en mots, en tension. En suite, le génitif de l´expression privilégié, « le sentiment du monde », c´est le jeu que se donne entre la subjectivité et l´objectivité, le « moi » et le « monde », instituant une intentionnalité ambiguë et incomplète entre les termes. Cette intentionnalité forme une distance intentionnel, i.e., la composition d´images qui naît tantôt d´un, tantôt d´autre, pour miroitement ou réversion.Item type:Item, Bioensaios de decomposição anaeróbia de macrófitas aquáticas da lagoa do Óleo (Estação Ecológica de Jataí, Luiz Antônio - SP)(Universidade Federal de São Carlos, 2005-05-11) ;Romeiro, Francisco ;Bianchini Júnior, Irineuhttps://lattes.cnpq.br/0659731944736389This study aimed at investigating: i) the influence of temperature on decomposition of macrophyte detritus; ii) the importance of leaching in the dynamics of the decomposition; iii) the decomposition of different structures of aquatic plants and iv) the enzyme activity of xylanase during the decomposition. The samples of water and aquatic macrophytes were collected in the Óleo lagoon (Ecological Station of Jataí; 21º 36 S and 47º 49 W). Bioassays were performance (during 140 to 200 days) with macrophytes fragments and water samples incubated under controlled conditions. Periodically the productions of carbon dioxide (CO2) and methane (CH4) were determinate by gas chromatography and the enzymatic activities were measured from reaction mixtures (aliquots of the incubations and xylan solution) followed by reducing sugars dosage (colorimetric method). It was observed a positive correlation with temperature and detritus decomposition; once were verified greater consumption at higher temperatures. Temperature was important in the detritus fibrous fraction consumption (Q10 = 1.61) and in methanogenesis (Q10 = 3.17). The fractionating of dissolved (DOM) and particulate organic matter (POM), due to the leaching process, conduced to a increase in the consumption efficiencies of these fraction. The xylanase activity was only registered when the dissolved sugars leached from the detritus decreased. The roots were the most easily degraded structure of Scirpus cubensis; this specie was the most easily degraded, followed by Cabomba furcata; the Ludwigia inclinata was the most refractory. Overall, this study suggests that S. cubensis is one of the most important aquatic plant to the carbon cycling in the Óleo lagoon, once this specie present higher productivity and intense mineralization.Item type:Item, O uso da teoria de conjuntos aproximados na modelagem de bases de dados relacionais e na extração de conhecimento(Universidade Federal de São Carlos, 2005-05-13) ;Vieira, João Marcos ;Nicoletti, Maria do Carmohttps://lattes.cnpq.br/6454154048263145This work investigates two relational database models that extend the standard relational database model. Both models extend the standard relational model by allowing ways to represent uncertainty. The rough relational database model borrows the basic concepts form the rough set theory and deals with uncertainty by approaching relations using their lower and upper approximations. The fuzzy rough relational database model generalizes the rough relational model by introducing a degree of membership associated to elements, in a rough relation. The operators that are an intrinsic part of each of the models are formally defined and their pseudocodes are presented and discussed in details. A prototype system ROUGH-ID3, which implements a hybrid knowledge extraction approach by integrating a set of rough database operators with the symbolic system ID3 is proposed.Item type:Item, Comportamento do psicólogo em Instituição de atendimento a deficientes mentais: contribuições da análise do comportamento para construção de uma prática crítica e relevante(Universidade Federal de São Carlos, 2005-05-13) ;Queiroz, Heloísa LopesCortegoso, Ana LúciaCurrent conceptions of mental disabilities and the types of services needed by the mentally disabled point to the need to increase their autonomy and inclusion to the greatest extent possible, in relation to the living conditions of the non-disabled population. In the realm of psychology, despite the existence of knowledge relevant for producing actions compatible with this guideline, what is often observed among psychology professionals are actions related to establishing classifications and remedial interventions for problems that have established themselves, rather than actions that contribute to the effective understanding of the special needs of the mentally disabled, and interventions to promote behaviors that favor inclusion. In order for these changes to occur, relative to the actions of psychologists when attending to the mentally disabled, it is important to identify, describe and analyze behaviors that guarantee a new repertoire of actions for psychologists that work in institutions serving this population, promoting prevention of mental disabilities and maintenance of significant behaviors in psychologists treatment of the mentally disabled. This seems possible, considering existing knowledge regarding human behavior and how to deal with it. Thus, the proposal of this study was to identify and characterize, as environment-action relationships of the organism, behaviors of the psychology professional when acting to treat individuals who are mentally disabled, considering current practice and the available knowledge regarding the needs and challenges of serving this population. Information was gathered on the existing behavior, and desirable behavior, of psychologists in institutions serving the mentally disabled, in order to produce descriptions of the behavioral relationships that define the of professionals in this context. The information was obtained through interviews conducted with the psychologists and other high-level professionals that form part of the teams in two institutions serving the mentally disabled in the interior of the state of São Paulo. Based on this information, descriptions of the behavior of the psychologists were produced as a starting point for a more adequate understanding of their current repertoire and occasional gaps in this repertoire. Information was also obtained from the available literature related to behaviors, or aspects of behaviors, of these professionals that were considered relevant to the treatment of the mentally disabled, in institutional contexts, and compared to the descriptions produced, from the perspective of the interviewees, which then lead to complementation, revision, or even substitution of behaviors previously identified. It is hoped that the knowledge produced as a result of this study may contribute to improved education and training of these professionals, whether in their undergraduate or graduate studies, or the continuing education of professionals in the institutions themselves.Item type:Item, Transferência de tecnologia através de spin-offs: os desafios enfrentados pela UFSCar(Universidade Federal de São Carlos, 2005-05-13) ;Azevedo, Gustavo Carrer IgnácioTorkomian, Ana Lúcia VitaleWith the appearance of a new world scenery, the markets are dominated by companies with high capacity of innovation. The university, one of the most important sources of knowledge, which fundamental role consists in the formation of human resources and in the performance of academic research, starts to be forced in a way that the results of its researches should bring more relevant economic and social impacts to the society in order to enrich and enlarge its role. As a consequence, the relationships of cooperation between universities and companies and the process of technology transfer from the university to the market gain importance. Among the known process of technology transfer, the creation of companies from the knowledge generated in the university (academic spin-offs), emerges as an alternative way to complement the traditional mechanisms. This study aims to characterize the process of technology transfer through the academic spin-offs, focusing the Federal University of São Carlos, and to identify its importance in the process of innovation, the employment creation, the relationships of cooperation between the university and companies and the local economic development. The methodology used was the qualitative research and case study, with field interviews and analysis of the contents. The results also show the received incentives and the main barriers faced by the academic spin-offs.Item type:Item, Estratégias cognitivas para o aumento da qualidade do hiperdocumento para educação a distância(Universidade Federal de São Carlos, 2005-05-17) ;Almeida, Vânia Paula de ;Silva, Junia Coutinho Anacletohttps://lattes.cnpq.br/6200743168568684Actually, the concern with the quality of the products is present in all areas. In Distance Learning (DL), this concern should be even higher. The inherent difficulties of the physical distance between teachers and students enhance the necessity of teachers prepared to the edition of well planed courses, computer environments with adjusted resources and easy to be used, and students motivated to learn in distance. To have an effective process of teaching and learning in DL, it is necessary to support teachers during the instructional material development, helping them to establish the material structure, navigation, organization and layout, considering pedagogical aspects to facilitate the student knowledge construction. In this context, the objective of this work was to validate the use of some cognitive operators in DL context, verifying if the content organization resulted from the use of the cognitive operators enhance the hyper document usability and so its quality. To evaluate the use of the cognitive strategies in DL context, comparative studies were done in which usability evaluations were applied in hyper documents with and without operators.Item type:Item, Formação de agregados gelatinosos em culturas de microalgas de um reservatório eutrofizado (rio Tietê/SP)(Universidade Federal de São Carlos, 2005-05-18) ;Ortolano, Pedro Ivo Coelho ;Vieira, Armando Augusto Henriqueshttps://lattes.cnpq.br/4428377384377272This work presents original data about aggregate formation by two diatoms, Aulacoseira granulata and Thalassiosira cf. duostra, isolated from Barra Bonita reservoir (Tietê river/ SP). Experiments were performed using a Couette floculator, a machine that promotes laminar fluid shear rates (G, s-1), in which particles in movement with several velocities will shock. Depending on their stickiness, the particles may or may not form aggregates. It was determined that different fluid shear rates can affect distinctly aggregate formation by the two algal species. At shear rates of 10 s-1, T. cf. duostra formed aggregates more intensively than A. granulata. However, aggregate formation by A. granulata was greater at a lower shear rate (3 s-1). The role of exopolysaccharides (EPS) produced by these species in aggregate formation by their cells/chains was also studied. The results showed that these compounds enhanced aggregation by both species. The addition of A. granulata EPS in Barra Bonita water, leaded to the formation of aggregates with larger relative surfaces (µm2) when compared to aggregates formed in Barra Bonita water in the absence of these compounds. This effect could be related to the hydrofobic characteristics of A. granulata EPS, which is composed of large amounts of terminal deoxy-sugars (fucose and rhamnose). When A. granulata chains were added to Barra Bonita water, the formed aggregates presented also larger relative surfaces. This increment leads to greater sinking rates and can promote important consequences for the cycling of matter in Barra Bonita reservoir.Item type:Item, Reestruturação agroindustrial e mudanças institucionais na rede láctea paulista.(Universidade Federal de São Carlos, 2005-05-19) ;Cunha, Juliano Cavalheiro da ;Paulillo, Luiz Fernando de Oriani ehttps://lattes.cnpq.br/9919942357089937In a very complex sector like the milk it is important to discuss the Govern action. This issue has been discussed very hard in all international meetings about trading. In the Brazilian case its possible to visualize two different periods of Government action, the regulation and the self-regulation. So, the processes between these periods has caused different kind of impacts to the actors. Among all the problems created are the exclusion of milk producers, workers and cooperatives. The main issue of this work are the changes happened in the beginning of ninety years, when the Government stopped regulating the milk sector. Another objective is to describe and analyze the formation of the milk policy network in the São Paulo state considering the institutional environment and the governance structure. The object of analyze is the milk policy network, the unit of analyze is the negotiation among the actors and the variable of analyzes are the power resources (constitutional, policy, financial, organizational, technological and juridical).Item type:Item, Operadores pseudo-diferenciais e espaços de Hardy(Universidade Federal de São Carlos, 2005-05-20) ;Kapp, Rafael Augusto dos Santos ;Hounie, Jorge Guillermohttps://lattes.cnpq.br/7302904386484949Obs.:Devido a restrições dos caracteres especias, verifcar abstract em texto completo para download.Item type:Item, Um sistema para recuperação de imagens com base em características geométricas, conjuntos nebulosos e indexação métrica(Universidade Federal de São Carlos, 2005-05-20) ;Gavioli, Alan ;Biajiz, Maurohttps://lattes.cnpq.br/8331600770992494In this work, the MIGFIR (Metric Indexing and Geometric Features-based Image Retrieval) system is presented. This system was developed mainly to make possible to index and retrieve certain image classes (like human face images, for example) with efficiency and accuracy using geometric measures, two new similarity functions and the metric access method called Slim-tree. This system also allows configuring important parameters during the definition of queries and makes possible to apply fuzzy sets and related concepts so that the language used in search expressions of one of the query classes that are supported be considerably close of the language usually applied by human beings. Efficiency and accuracy of the system at the execution of queries on several real and synthetic human face image sets are also presented. About efficiency, the obtained results show that MIGFIR can promote a quite considerable reduction of the execution time of queries in comparison with a similar approach that applies sequential scanning of the data. About accuracy, the results show that performance is satisfactory during the retrieval of human faces similar to certain example-images.Item type:Item, Uma arquitetura baseada em componentes para adaptação de conteúdo na Internet(Universidade Federal de São Carlos, 2005-05-20) ;Claudino, Renato André Takayama ;Souza, Wanderley Lopes de ;https://lattes.cnpq.br/3742302894743620https://lattes.cnpq.br/4530488988781991Item type:Item, Transientes, monoestabilidade e biestabilidade em processos de oxidação de eletrodos metálicos com formação de filmes : alguns casos simples(Universidade Federal de São Carlos, 2005-05-23) ;Brito, Gilberto Augusto de Oliveira ;D'Alkaine, Carlos Ventura ;https://lattes.cnpq.br/8699821828310072https://lattes.cnpq.br/8769820118747855The simulation of simple models studied in this thesis showed that experimental current density/potential curves from processes of metal electrode oxidation with film formation can present peaks or discontinuities besides these curves can present the polarographic wave shape (sigmoidal shape). The experimental current density/potential curves wouldn t present hysteresis on quasi-stationary conditions. The peaks can be the result of measures made in non stationary conditions (transient conditions with measure times smaller than the relaxation time of the physical system under study) or conditions which looks like stationary conditions (transient conditons with measurement times bigger than the relaxation time of the physical system under study which could seem as stationary conditions) and the descontinuities would be the result of measures made in conditions which looks like stationary conditions. The experimental current density/potential curves presenting a peak or polarographic wave shape under conditions which looks like stationary conditions would point out that the physical system is in a monostability zone while those curves presenting discontinuities under conditions which looks like stationary conditions would point out that the physical system is in a bistability zone. Another important conclusion (obtained from the simulations) is that peaks and discontinuities in experimental current density/potential curves which are associated to the active/passive transition phenomenon can be the result of others phenomena. The stationary current density/potential curves simulated with the one adsorbed specie and constant dissolution model and the two adsorbed species and constant dissolution model, present the polarographic wave shape (this one due to these models are in a monostability zone) while the transient current density/potential curves present a peak. The stationary current density/potential curves simulated with the one adsorbed specie and oxide dissolution depending on coverage degree model and the two adsorbed species and oxide dissolution depending on coverage degree model can present the polarographic wave shape or a peak or hysteresis (hysteresis is due to these models are in a bistability zone) while the transient /E curves can present a peak or discontinuities (discontinuities are due to these models are in a bistability zone). Besides, the two adsorbed species and oxide dissolution depending on coverage degree model can present a kind of irreversibility when it is in a bistability zone.Item type:Item, Linguagem de padrões para apoiar o projeto de material instrucional para EAD(Universidade Federal de São Carlos, 2005-05-23) ;Talarico Neto, Américo ;Silva, Junia Coutinho Anacletohttps://lattes.cnpq.br/6200743168568684Item type:Item, Aplicabilidade de padrões de interação humano-computador e de engenharia de software no processo de desenvolvimento de sistemas interativos(Universidade Federal de São Carlos, 2005-05-23) ;Silva, André Constantino da ;Silva, Junia Coutinho Anacletohttps://lattes.cnpq.br/6200743168568684Both Software Engineering (SE) and Human-Computer Interaction (HCI), two areas within Computer Science, propose process models, methods, techniques and tools for interactive systems development. However, those areas differ in their view of the task: while the SE main focus is the software product and its process, HCI focuses the interaction aspects between men and machine. However those areas are complementary, and there is a need of integrating the two views in the interactive systems development in a way to approach and treat, in a clear and defined way, interaction and implementation jointly. Motivated by that need, and the idea of increasing the developed systems quality, this work explores the concept of computational patterns in the support to the interactive systems development so that these are to a process model. Relationships between SE and HCI patterns are identified, thus promoting the integration of SE and HCI views.
