A common problem to applications such as positron emission tomography, low-exposure X-ray imaging, fluorescence microscopy, optical and infrared astronomy, and others, is the degradation of the original signal by Poisson Noise. This problem arises in applications in which the image acquisition process is based on counting photons reaching a detector surface during a given exposure time. Recently, a new algorithm for image denoising, called Nonlocal-Means (NLM), was proposed. The NLM algorithm consists of a nonlocal approach that explores the inherent image redundancy for denoising, that is, it explores the principle in which, in natural images, there are similar regions, yet locally disjoint. NLM was originally proposed for additive noise reduction. The goal of this work is to extend the NLM algorithm for Poisson noise filtering. To achieve this goal, symmetric divergences, also known as stochastic distances, have been applied as similarity metrics to the NLM algorithm. Stochastic distances assume a parametric model for the data distribution. Therefore they can accommodate different stochastic noise models. However, knowledge of the model parameters is necessary to calculate the stochastic distances. In this research, estimation and non-local filtering schemes were considered under Poisson noise hypothesis, leading to competitive results with the state of- the-art.

First we briefly discuss the spectral properties of the Robin Laplacian in a straight and infinitely long planar strip with Robin coupling parameter changing signs. Assuming that such parameter is a constant outside a compact set, we find the essential spectrum, and also derive a sufficient condition that guarantees the existence of bound states. Next, we have studied the Laplacian in some thin curved domains in the plane and space, with a particular type of Robin boundary conditions and cross-sections; such conditions are nonhomogeneous, in the sense that the Robin coupling parameter depends on the curvature of the reference curve. We derive, when the diameter of the cross sections tends to zero, effective operators by means of a kind of convergence of the resolvents. With such modeling framework, the main novelties are that the curvature contributes with a repulsive potential whereas the torsion (in the spatial case) plays no role to effective operators.

In this paper we reflect on a group of eight lessons applied in the eighth year of elementary school. In these classes, we treat the Pythagorean Theorem, seeking to justify this outcome appropriate to the student s eighth grade elementary school mode. We were interested in seeking justifications with historical content, to rescue, to the extent possible, a part of the history of the Pythagorean Theorem. We take care to seek a mathematical justification for each procedure adopted to develop pedagogical activities. Throughout the text brushing been several suggestions for improving the finished product, though it kept almost entirely in Appendix 1. Also critical to our work interweave throughout the text, seeking both personal growth as offering the opportunity for a better match of the final product to whom this is of interest. At the end we suggest some current applications of the Pythagorean Theorem. Finished the job in the classroom involving the class with the game of dominoes, adapted to the content studied, trying to leave a better final impression on the students. We describe the construction of pedagogical object, the math worked during such construction and finally its application in the classroom. We make four appendices. In the first present the final product. In the second we seek to exemplify the student s work. In the third and fourth work building Pythagorean triangles.

In this work, a new minimally invasive (ICPmi) and an invasive (ICPi) intracranial pressure (ICP) monitoring methods were used to evaluate intracranial pressure behavior in chronic epileptic rats, induced by the experimental model of pilocarpine. Using adult Wistar rats after three months from pilocarpine induced status epilepticus or control procedures, animals underwent a procedure for magnetic resonance imaging acquisition in order to verify volumetric changes in the hippocampal regions. Then, their ICPs were monitored simultaneously for 1 h using ICPmi and ICPi methods, followed by Neo-Timm histological processing of their brains after a week. Analyses consisted of spontaneous recurrent seizures (SRSs) frequency quantification for the pilocarpine group; and for both groups, volume determination of the hippocampal regions using MRI techniques, short-time Fourier transform for ICPi and spectral frequency determinations for ICPmi and ICPi, and mossy fiber sprouting presence verification. Spectral frequency analysis demonstrated a correspondence between ICPmi and ICPi in the frequency domain for both groups. For short-time Fourier transform analysis, oscillations along monitoring time in the ICP frequency were noticeable for the epileptic compared with the control animals. SRSs frequency quantification for the chronic epileptic animals showed an increasing number of seizures along experimental time. Tissue volume measurements for rostral, caudal and total hippocampus showed statistically significant reductions in the pilocarpine group compared to the control. All animals from the epileptic group presented mossy fiber sprouting in comparison with the control group. ICP characteristics of individuals with epilepsy are not elucidated in the literature, since there are few studies associating these two important neurological factors. This work is intended to provide a preliminary experimental approach to these topics of major public health importance.

The focus of this work was to watch, in the speeches of InterpreterTranslators of the Language of Signs (TILS), the understanding and the conceptions that they have concerning your function in the process of the deaf student's formation and of the professional alterities constitution of them. We based our study theoretically in the enunciativo-discursive language theory of Mikhail Bakhtin and, to leave of that referential, we defined the methodological procedures , as then organization and the discussions presented in the results. We left of the presupposition that to understand the subjects it is necessary to request to place them in your reality, in the universe of relationships in which they are submerged, and that are decisive the construction of meanings and the relationships and interactions for them established, considering, still, the researcher's active paper in the construction of the data. It participated with us, in the interviews and interactions, 27 TILS, located in series of the Fundamental Teaching II (6th to the 9th year), in schools of the municipal public nets of 8 (eight) Brazilian states. The interviews were recorded, and we did, also, annotations of context elements, important for the understanding of the subjects and yours speeches. We created dialogue spaces and reflection concerning the elements that guide the social practices of these subjects in your professional contexts and, leaving of discussions centered in the speech concepts, subject, dialogy and ideology, we cleaned our perception on the construction of the senses and meanings attributed by the TILS to your material realities and related universes, besides the function of the speeches in the manners as the subject of the research understand your function and responsibilities and they look at the work place for them in the sceneries of development of the deaf students' schooling. Among ours (in) conclusions, detached that the local sceneries indicate significant changes in course in what plays to the deaf students' education and, mainly, in the relationship with the TILS. The plurality of professional entails and of wages it demonstrated that there is a lot to be done in this field of the rights and duties. The suitable situations for the subjects also appeared for the distance among what it would be the ideal and what is the Real in the implantation of bilingual educational projects. We saw as indispensable the support offer to the faculty, as well as the need of the TILS of if they feel part of the teaching team and they develop partnership relationships with the teachers. We saw, also, that the realities and singularities lived by the performance in school atmospheres they hinder these professionals excessively to define your roles, the limits of your responsibilities in the teaching process and of the deaf students' learning. Finally, on formation, professionalization and politization of the TILS, we believed that are aspects they be constantly pursued her, not just in your dimension individual, but collective, considering the interlacement and the crossings of the aspects political, ideological, philosophical, that constitute them in the group of your professional identities. With relationship to the unfoldings of this research, because the done questions raised many other, we believed, mainly, in the importance and need to think on her the formation in a deep and connected way to the beginnings of the alterity. And, still, we waited that, after materializing doubts, conflicts, anguishes and reflections of TILS, this material can serve, also, to the formulation of new and others idealize and ideas of professional formation for them.

Brazil produces about 37 million cubic meters of charcoal per year whit an increasing due to the gradual coal replacement, once the coal mined in Brazil does not have adequate levels of carbon for some purposes, such as power generation. However, the large amount of coal found in all terrestrial crust propitiates an extremely low cost this product. Regarding to it, whit the intent to add value to the coal and provide an adequate destination to by-product (fine) of the charcoal, it was made briquettes of coal blends. For briquettes production it was used coal and charcoal fines, corn starch and boiling water at different proportions, summing up 25 treatments. Ten samples were made for each treatment, summing 250 specimens, wich were analyzed by the moisture content, proximate analysis, density, mechanical strength and thermal analysis. The treatments without the addition of binder were discarded because briquettes could not be formed from them. Other treatments had good features, reaching satisfactory results expect in relation to the formation briquettes (average mechanical strength of 0,2 MPa), presenting good mechanical strength for commercial application. According to the increased proportion of charcoal in the blend, the produced briquette achieved better results, mainly to thermal properties due to higher fixed carbon content (compared to coal) and reduced ash content, an appropriate behavior for various industrial and even residential applications. It was concluded that the use of by-products from vegetable and coal briquettes was technically feasible, providing advantageous physical characteristics for storage and transportation.

This work studies the ship routing and scheduling problem in oil transportation from offshore platforms to inland terminals. It is motivated by a real situation in a Brazilian oil company. Brazil is one of the world's greatest oil producers and has around 80% of its oil explored in offshore mode. Thus, transportation costs play an important role in achieving operational excellence, and the recent growth trends for oil exploration in Brazil has transformed its operations and demanded agile and effective decision support systems for addressing the oil sector dynamism. This work's goal consists in developing and applying an optimization-based approach using a mixed integer linear programming model in real decision-making situations, along with a solution method based on mathematical programming (MIP-heuristics) in order to solve the model, such as relax-and-fix. The proposed model is inspired in a problem formulation for pickup and delivery with time windows (PDPTW) and heterogeneous fleet, where costs incurred for fuel consumption and fleet contracts is the objective function to be minimized. The pickup and delivery pairs are predetermined and the model's main decision refers to ship allocation to these pairs compounding a route. Furthermore, some additional constraints are modeled and proposed, such as terminal access and platform mooring limitation according to ship types, as well as product blend incompatibility. The model was implemented in a modeling language along with an optimizarion software. Computational experiments with the model and the heuristics are presented for different data sets supplied by the case study company. These experiments show the potential benefits of this approach for finding good solutions for the problem as well as the dificulty in finding solutions for realistic instances due to its NP-hard characteristics.

In the electronics industry the companies owners of brands ( OEM ) are hiring outside manufacturing service providers ( EMS ) , and transfer to them major portions of their production. The EMSs have contributed to the OEMs in activities such as supply of components, engineering, manufacturing and distribution services. With the growth of this practice, the EMSs accumulate ever more capacity as providers of highly specialized commoditized electronic products, reducing costs and sharing risks across the electronic industry.The objective of this research was to scale the perception among EMSs, about the attributes of trust, mutuality and leadership, governance mechanisms as complementary to contract manufacturing in the consumer electronics industry considering the contributions of Ménard (2004) for the development of hybrid modes of governance. A field survey was carried out, being interviewed companies providing contract manufacturing headquartered in São Paulo. The analyzes show that allowed transactions providing electronic manufacturing are coordinated by complementary mechanisms to contracts through a governance model multiple hybrid formed by trust, mutuality and leadership.

In this thesis, we have investigated the optical and transport properties of a p-i-n GaAs-AlAs resonant tunneling diode (RTD). The possibility of controlling and significantly varying the density of carriers accumulated at different layers of this structure simply by applying an external bias makes it very useful to investigate various fundamental issues. Furthermore, the process of tunneling that critically depends on the alignment from confined energy levels and the injection of carriers that attain quasi - equilibrium distribution at distinct accumulation layers makes this structure very special for analyzing optical properties in general, and in special, spin-polarization effects when an external magnetic field is applied to the RTD. Particularly, two emission bands were observed for the quantum well (QW) of our structure and were associated to the recombination of electrons and holes that tunnel into the QW and may recombine either as an exciton involving the fundamental states of the QW or a transition involving an acceptor state in the QW. It was also observed that the relative intensity of these emission bands strongly depend on the applied bias voltage. The optical recombination involving acceptors states becomes relatively more efficient as compared to the excitonic recombination for higher densities of electrons in the QW. This effect was discussed considering how the electron carrier density depends on the applied voltage and other effects such the capture rate of holes by the acceptors and electron and hole differences concerning mobility, effective mass and tunneling processes. We have also investigated spin properties of the tunneling carriers in our device by measuring the polarization-resolved electroluminescence from the quantum well (QW) and the contact layers under low temperatures and high magnetic fields, up to 15 T. Under these conditions, we have observed that the QW emission presents a large negative polarization degree which depends on the external applied bias voltage. The VII QW spin polarization shows oscillations and abrupt changes at the electron resonant peak. The results are mainly attributed to the abrupt changes of intensity of the two QW emission lines. Furthermore, the contact-layer emission have also shown voltage dependent emission lines that were attributed to the two-dimensional electron gas formed at the accumulation layer under an applied bias. The contact-layer emission presents a large negative polarization degree which is also voltage dependent. The QW spin polarization degree was discussed considering different effects such as the presence of neutral acceptors in the QW, the voltage control of carrier densities in the device, hole and electron tunneling processes and the spin injection of spin polarized two-dimensional gases formed at the accumulation layers.

The privacy guarantee of a person s data is understood as the capacity of this person to manage, store, change, restrict or disclose for groups of individual of his choice. The data shared can be sensitive, revealing private content that deserves protection in sharing, for example financial personal information. In many computing services a lot of sensitive data does not have any mechanism that guarantees the owner s privacy. This work shows a mechanism that guarantees the privacy of the person who has the data accessed, the data owner, and the privacy of the person who accesses the data. It was developed a cloud monitoring mechanism for data whose access needs to be monitored with intrusion detection scenario available for the data owner. The propose feasibility was evaluated by response time test of a monitored page access, server overload and the server resource consumption through the prism of an application using the mechanism. Such mechanism has been a viable solution due to its minimal impact in computational resources and a solution that assists in sensitive data access monitoring.

In this work we study vertex models with non-diagonal boundaries, characterized by reection matrices with an upper triangular form. By means of an extension of the algebraic Bethe ansatz, we construct generalized Bethe states as well as the respective eigenvalues for two classes of models: six and nineteen vertex models. As usual, in both cases the exact solution is given in terms of the Bethe equations.

In the mid-1990s, Brazil becomes a signatory to documents assume Inclusive Education as a fundamental task for any country. The deaf education from the perspective of inclusive education, bilingual education and advocates regarding the involvement of different professionals. Among them is given the emphasis on the role of Teacher Interlocutor of Libras (PI). The PI is one of the recent positions that compose the staff of the state of São Paulo Public Schools. Is predicted that he works at schools from state schools who present deaf or hard of hearing students regularly enrolled, with the task of conducting the dialogue between teachers and students with deafness and / or hearing impairment. This study aims to analyze a strategy of continuing education for teachers interlocutors. Three PIs working in state schools in a midsize city of São Paulo participated in this research. The participants comprised a group of training who proposed hold discussions and reflections on the activities of PIs, based on theoretical studies and exchanges of experience. Training group meetings occurred weekly with an average duration of two hours each, totaling ten meetings. Data collected during the training group (open questionnaire, script analysis of the filming of the group, script analysis of the filming of the action of PI and training group transcripts) were discussed in three areas of analysis: 1) The role / function of PI in the classroom and school; 2) Challenges, possibilities and limits of action of PI; and 3) the training group as a space for dialogue / mediation among participants. Analysis of the sequences revealed the need for an area of continuing education among PIs in order to facilitate discussion and reflection on practice. The testimonies of PIs indicate the precariousness of education for deaf students in the reality experienced by the PIs and PRs, since there is not a guideline or a direction work, or even targets set to be followed. This shortcoming of goals and guidelines causes confusion among the doings of each professional. The solutions remain palliative, work is carried out without tenders or purpose, and there is not a policy to bilingual inclusion for the deaf. We therefore conclude that a commitment to quality education for the deaf student becomes practically impossible in the absence of Pedagogical Political support and an effective project that embases and pay attention in fact to the practice of principles of governing a bilingual education for the deaf in school.

Difficulties in supplying the raw material, coagulated latex, to processing plants of natural rubber from São Paulo are very present in this productive activity. The rubber industry also presents such scarcity problem with the supply of the natural rubber raw material, the GEB (Granulado Escuro Brasileiro). This scenario has always been present in the history of the natural rubber chain, having had, in some periods, the intervention of the State through public policies and the obligation to heveiculture fomentation by the rubber industry. The state of São Paulo is the biggest natural rubber producer, with the largest area of rubber tree plantation, in Brazil and it also concentrates a major part of processing plants. The thesis main objective is to analyze the processing companies (plants and rubber industries) transactions of natural rubber with their suppliers in the state of São Paulo. In order to achieve such objective, a characterization was carried out of the business attributes of the governance structure adopted by processing companies to ensure their raw material supply. The theoretical framework of the New Institutional Economics (NIE) and the Transaction Cost Economics (TCE) were also used. The understanding of the transactions carried out by the processing units in the raw material (coagulated latex) acquisition involves the description of the productive chain, the characterization of the institutional environment, the characteristics of the transaction and governance structures which are adopted by the processing companies located in the state of São Paulo. Agents of the rubber sector, plants, rubber industries and rubber producers were interviewed for such analysis in order to compose the institutional environment. The interviews resulted in five case studies (four plants and one rubber industry), which adopt forms of governance adaptive structures with their suppliers of the natural rubber. The transaction attributes of the processing companies with their suppliers are featured by: incomplete information (scarce or little information exchange), presence of uncertainty, an asset specificity (physical and dedicated to production), average frequency and price variation. The major presence of informal agreements and a mechanism of additions to the contract in the transaction are, mainly, guided by trust, reputation and authority. The analysis carried out showed that the transactions of the natural rubber supply for processing companies are ruled by mechanisms which are more complex than the TCE contracts. The presence of a high level of investment in specific assets, both in the heveiculture and in the processing, force agents into an approach and a long term relationship. In order to reduce the uncertainly in this economic activity, processing companies search for more than one way of governance representing a lower dependence of one supplier.

Traffic in large cities has become a challenge for the people who live there. In addition to economic and environmental damage, traffic chaos is responsible for countless victims annually, making it a leading cause of death worldwide. Among these victims, children between 0 and 14 suffer injuries due to traffic accidents as a leading cause of death. Only in Brazil, there are about 2,000 deaths involving children between the ages of 0 and 14 each year. The child is vulnerable in traffic due to immaturity and physical characteristics of this group, so it is necessary specific and targeted studies that support the government regarding the decision making and implementation of strategic actions to mitigate such a scenario. Thus, this study presents the scenario of traffic fatalities involving children in Brazilian traffic through indicators, as well as a comparison with socioeconomic indicators and the international scenario. The methodology included the calculation of primary indicators for all states, the geographical distribution of these rates, a comparison with the reality of other countries and the correlation of mortality indicators with socioeconomic ones. The countries chosen for the comparison with the Brazilian reality were those present in human development groups classified as: very high, high, and the ones which have similar or higher human development groups than the Brazilian scenario, and the ones which provide data for the calculation of indicators of mortality. In general, the Brazilian scenario is positive, since the rates are generally a decreasing curve. When considering economic development in relation to accidentality involving children, there was a negative and moderate correlation between mortality rates and GDP per capita for each state where performed. The correlations with Human Development Index (HDI) considering the year of the indicators showed a positive relationship. In international comparison, the indices showed a general decreasing trend in global accidentality rates, except in a few countries.

The aim of this study is to assess the potential effects of technical measures belong to the WTO TBT agreement on exports of Brazilian pulp and paper industry. The choice of this segment was due to the same consist of a major component of national export agenda, being susceptible to external regulations. For this, we employed a gravity model comprising Brazil and its importers who reported at least one technical measure within the analysis period 1997-2012. The econometric model, whose inference occurs through the Tobit method further comprises the GDP of the countries involved in trade , foreign tariffs for products affected, bilateral distances and the official languages of each of the trading partners considered. Through descriptive and statistical analyzes we found that greater attention is given to papers and supplies intended for toilet use and the information content present in these seems to be a decisive factor in purchasing their partners. The effect of technical measures on the segment revealed that some of the measures imposed are associated with lower export volumes, thus suggesting greater trade between the same restriction as notifications to the production processes on the product, as well as measures involving compliance which can influence the cost structure of exporting in an effort to adapt its products. Thus, it is expected that the results found to contribute to greater understanding of the effect of technical measures on the pulp and paper industry, as well as the behavior of these requirements over others products of agribusiness.

The following research consists in a study about Argentina s linguistic history at the moment where Discourse Analysis studies were introduced. We show this process in relation to the historical moment in Argentina: the democratic normalization. Democracy brings important changes in the society and in the universities, mainly in humans and social science. The curricula were opened to news paradigms and, particularly, at the Letter Bachelor s at the University of Buenos Aires. Linguistic was consolidated as a main discipline with her owns orientations. In this way, the Linguistic program was reformulated and a new discipline is defined: Elementos de Semiología y Análisis del Discurso . Our study consists in thinking about these changes in the research and academic s domains in which form Discourse Analysis were established and which were their characteristics. The approach is based on the concept of history by Foucault, the linguistics historiography and the notions of archive and conditions of production from Discourse Analysis. We consider which were the linguistic materials analyses and in which concepts and methodology the studies were developed. Finally, we concluded that the corpora analyzed in papers and in the two disciplines are strongly related with the context of democratization in Argentina and the analysis show a huge engagement with this reality in a latinoamerican context.

Qualitative studies show that Lean Manufacturing implementation in Small and Medium Enterprises (SME) is performed in an informal way. Within this context, the main goal of this paper is to investigate the most commonly used Lean Manufacturing practices that are being implemented within Brazilian SME’s companies. In addition, this paper also aims at presenting what is lean manufacturing in the view of SME in Brazil. The research method used in this paper was an exploratory survey. The results show that the studied companies use practices in a fragmented way, not having a holistic view of lean manufacturing which is considered as being one of the most important part of such philosophy. This represents an opportunity for the studied companies.

This research aims to understand the process of initiation into teaching of graduates of Institutional Scholarships Program initiation into Teaching (PIBID) at the Federal University of São Carlos, in the area of Mathematics. In order to identify the contributions and limitations of this formative process, under the gaze of the scholars graduating from the same, we seek to answer the following question: what are the main guiding perceptions of the graduates of the PIBID/UFSCar of Mathematics in its process of initiation to teaching, about difficulties and learning of teaching career? We left a few theoretical assumptions of the learnings teachers (MIZUKAMI ET. AL., 2003; TANCREDI, 2009, GUARNIERI, 1996, 2005), and in particular, the initial stage of career (HUBERMAN, 1995; VEENMAN, 1988; CAVACO, 1995; MARCELO GARCIA, 1999; TARDIF, 2012), which has its own characteristics and is usually marked by feelings of "survival" and "discovery" that may influence the permanence or not on teaching career. For recognition of the scenario, identifying the dynamics and particularities of the programme at the national level and institutional, were used documents, projects and publications. For data collection we chose three steps. First perform the mapping of the scholars who participated in the program, in which count 35 scholars in 3 years of subproject and routing of a questionnaire. The initial questionnaire included data about initial training, training in the PIBID and professional experiences, including teaching jobs or not, in order to draw the profile of the scholars and alumni. This step also seek to identify the graduates who followed the teaching career for the deepening of the data thus followed five subjects for the second step. This was created by the analysis of the reflective writings of graduates still at the beginning of their careers, in order to identify and: the main activities developed in the PIBID. In the third and final step, we conducted interviews with four subjects employees (Amanda, Beatriz, Olavo and Viviane), teachers graduates, in order to understand perceptions about the process of training, entry into the profession and future prospects. We look to analyze data from graduates of the PIBID/UFSCar/Mathematics through their difficulties and learnings narrated, composing two axes of analysis: (1) Characteristic Aspects of early career and (2) Dichotomies and joints of training and professional practice. The characteristics and feelings of teachers beginners pointed by literature are revealed in all the subjects ' initiation process, starting in experiences in the following program in the early years of teaching, but with few indications that some difficulties are overcome by the learnings generated at the time of formation, which contributes to the professional insertion. The program also seeks to provide the articulation between theory and practice to licenciandos, seeking to overcome the dichotomies between School Mathematics and mathematics academic training that reflects directly in professional practice. Also highlight the continuing training, realize their trajectories, their gaps, difficulties arising from inexperience. However, are reflective and interested in becoming increasingly better teachers and to develop professionally in career.
