A balança comercial do agronegócio brasileiro no período de 1997 a 2017: uma proposta de revisão / The Brazilian agribusiness trade balance during the period of 1997 to 2007: a review proposal

Ana Maria Marvulle Goffredo 02 July 2018 (has links)
A expressão agronegócio (agribusiness) originou-se na Universidade de Harvard na School of Business Administration, em 1957, com a publicação do livro A Concept of Agribusiness, de John Davis e Ray Goldberg. A ideia do agronegócio resulta em uma cadeia produtiva, com vários elos bastante interdependentes, das fases de produção até a comercialização do produto final O Brasil é visto por especialistas como um potencial fornecedor de alimentos global. E assim, a manutenção e o crescimento da participação produtiva do setor agrícola e pecuário nacional dependem de questões relacionadas à tecnologia. A problemática do trabalho envolve questões da diferenciação entre agropecuária e agronegócio. As fontes de referências de dados trazem informações, mas não englobam atividades da pré-produção, por isso, procurou-se responder: Não seria mais apropriado acrescentar a esta balança comercial os setores para trás, já que se trata como agronegócio? O objetivo é analisar por outra perspectiva os dados da balança comercial do agronegócio, propondo a adição de insumos intrínsecos aos produtos agropecuários, sob a ótica das intensidades tecnológicas, analisando seu comportamento no período de 1997 a 2017, permitindo assim, discorrer sobre o desempenho dos principais grupos de produtos da pauta de exportação e importação desse setor que serve de alicerce para a economia brasileira. Os resultados apontaram para fez diferença em termos de contribuição para a balança comercial do agronegócio a inclusão dos grupos de produtos peixes e crustáceos; produtos farmacêuticos; adubos (fertilizantes); e tratores na nova proposta a contribuição para a balança comercial total é menor. Ademais, os dados mostraram que o país tem dependência externa das vacinas e dos adubos e que esses produtos são de alta e média-alta intensidade tecnológica. / The term agribusiness originated at Harvard University at the School of Business Administration in 1957 with the publication of A Concept of Agribusiness by John Davis and Ray Goldberg. The idea of agribusiness results in a productive chain, with several interdependent links, from the production phases to the commercialization of the final product. Brazil is seen by experts as a potential global food supplier. The maintenance and growth of the productive participation of the national agricultural and livestock sector depends on issues related to technology. The problem of this papers involves issues of differentiation between agriculture and agribusiness. The sources of data references provide information, but do not include pre-production activities, so we tried to answer: Would it not be more appropriate to add the input sector to this trade balance, since it is called as agribusiness? The objective is to analyze from another perspective the agribusiness trade balance data, proposing the addition of intrinsic inputs to agricultural products, from the perspective of technological intensities, analyzing their behavior in the period from 1997 to 2017, thus allowing a discussion on the performance of the agribusinesses. main product groups of the export and import tariff of this sector that serves as a foundation for the Brazilian economy. The results pointed to the difference in terms of the contribution to the agribusiness trade balance to include the fish and crustaceans product groups; pharmaceutical products; fertilizers; and tractors in the new proposal the contribution to the total trade balance is lower. In addition, the data showed that the country has external dependence on vaccines and fertilizers and that these products are high and medium-high technological intensity.

Treatment of a cyanide-free copper electroplating solution by electrodialysis: study of ion transport and evaluation of water and inputs recovery

Scarazzato, Tatiana 27 February 2018 (has links)
Los dos baños de cobre más utilizados comercialmente son el baño ácido a base de sulfato y el baño alcalino a base de cianuro. Los baños alcalinos son utilizados principalmente para producir recubrimientos en piezas con geometría compleja y para evitar la deposición galvánica cuando se deposita un metal en un sustrato menos noble. Debido a la toxicidad de los compuestos de cianuro, se han desarrollado baños alternativos usando diferentes agentes complejantes. El punto de partida de la presente investigación es un baño primario sin cianuros para deposición de cobre en sustratos de Zamak desarrollado en el Instituto de Investigaciones Tecnológicas del Estado de Sao Paulo / Brasil. La sustitución de materias primas como el cianuro debe ser económicamente ventajosa y técnicamente viable. De esta manera, la investigación presentada pretendió proponer una alternativa para el tratamiento de residuos líquidos del baño ya mencionado con la finalidad de recuperar de manera simultánea el agua y las materias primas en un sistema cerrado. Se ha estudiado el proceso de separación por membranas de intercambio iónico, la electrodiálisis, usando un sistema en escala de laboratorio y una disolución sintética que simulaba las aguas residuales del baño a base de HEDP. Se ha evaluado la viabilidad del sistema por medio del análisis de los parámetros de operación, como la extracción de iones, la tasa de desmineralización, el porcentaje de concentración, la eficiencia de la intensidad calculada para cada especie y el consumo medio de energía. Debido a que el ácido HEDP es un agente quelante, se ha evaluado el transporte de los quelatos Cu(II) HEDP a través de membranas de intercambio de aniones por medio de métodos electroquímicos. Se han construido curvas cronopotenciométricas y curvas intensidad-potencial para diferentes disoluciones sintéticas que contenían los mismos compuestos que el baño original. Se ha establecido la relación entre la presencia de los quelatos en las disoluciones y los grupos fijos de intercambio de aniones. Por fin, se han realizado las pruebas de deposición usando electrólitos conteniendo los compuestos reciclados y se han evaluado las características de los depósitos obtenidos. Los resultados indicaron que el sistema de electrodiálisis usando membranas de intercambio de aniones con grupos de intercambio de base fuerte ha podido producir disoluciones tratadas y un concentrado conteniendo los iones del baño. Se ha podido añadir el concentrado al baño original para compensar eventuales perdidas del arrastre sin afectar la calidad de los depósitos. Por lo tanto, la aplicación de la electrodiálisis demostró ser una alternativa viable para la recuperación del agua y de las materias primas de la disolución evaluada, reduciendo la generación de residuos líquidos y ahorrando los recursos naturales. / The two most common commercial copper baths are the acid sulfate copper bath and the alkaline cyanide copper bath. Alkaline copper baths are mostly used to coat parts with complex geometry and to avoid galvanic deposition when depositing a metal on a less noble substrate. Because of the toxicity of cyanide compounds, alternative baths have been developed using different complexing agents. The starting point of the present study is a cyanide free strike bath developed for copper plating on Zamak substrates developed by the Institute for Technological Research of the State of São Paulo/ Brazil. The replacement of a raw material such as cyanide must be economically advantageous and technically feasible. Therefore, this study intended to propose an alternative to the treatment of liquid wastes from the mentioned bath, aiming at simultaneous water reclamation and chemicals recovery in a closed system. The electrodialysis membrane separation process was studied, using a laboratory-scale system operating with a synthetic solution simulating the rinsing waters from the HEDP-based bath. The feasibility of the technique was evaluated by analyzing operational parameters such as ion extraction, demineralization rate, concentration rate, current efficiency for each anionic specie and average energy consumption. Because HEDP is a chelating agent, the transport of Cu(II) HEDP chelates through anion exchange membranes was also evaluated by means of electrochemical methods. Chronopotentiometric and current-voltage curves were constructed for different model solutions containing the same compounds as the original bath. A relation between the presence of chelates in the solutions and the fixed ion exchange group could be established. Lastly, deposition tests were performed using electrolytes containing the recycled inputs and the characteristics of the coatings were analyzed. The results showed that an electrodialysis stack using strongly basic anion exchange membranes was suitable to produce treated solutions and a concentrate containing the ions from the bath. The concentrate could be added to the copper bath to compensate eventual drag-out losses without affecting the quality of the coatings. Thus, the application of electrodialysis was shown to be a feasible alternative for recovering water and inputs from the evaluated solution, reducing the wastewater generation and saving natural resources. / Els dos banys de coure més utilitzats comercialment són el bany àcid a base de sulfat i el bany alcalí a base de cianur. Els banys alcalins són utilitzats principalment per a produir recobriments en peces amb geometria complexa i per a evitar la deposició galvànica quan es deposita un metall en un substrat menys noble. A causa de la toxicitat dels compostos de cianur, s'han desenrotllat banys alternatius usant diferents agents complexants. El punt de partida de la present investigació és un bany primari sense cianurs per a deposició de coure en substrats de Zamak desenrotllat en l'Institut d'Investigacions Tecnològiques de l'Estat de Sao Paulo / Brasil. La substitució de matèries primeres com el cianur ha de ser econòmicament avantatjosa i tècnicament viable. D'aquesta manera, la investigació presentada va pretendre proposar una alternativa per al tractament de residus líquids del bany ja mencionat amb la finalitat de recuperar de manera simultània l'aigua i les matèries primeres en un sistema tancat. S'ha estudiat el procés de separació per membranes d'intercanvi iònic, electrodiàlisi, usant un sistema en escala de laboratori i una dissolució sintètica que simulava les aigües residuals del bany a base d'HEDP. S'ha avaluat la viabilitat del sistema per mitjà de l'anàlisi dels paràmetres d'operació, com l'extracció d'ions, la taxa de desmineralització, el percentatge de concentració, l'eficiència de la intensitat calculada per a cada espècie i el consum mitjà d'energia. Pel fet que l'àcid HEDP és un agent quelant, s'ha avaluat el transport dels quelats Cu (II)-HEDP a través de membranes d'intercanvi d'anions per mitjà de mètodes electroquímics. S'han construït corbes cronopotenciomètriques i corbes intensitat-potencial per a diferents dissolucions sintètiques que contenien els mateixos compostos que el bany original. S'ha establit la relació entre la presència dels quelats en les dissolucions i els grups fixos d'intercanvi d'anions. Finalment, s'han realitzat les proves de deposició usant electròlits contenint els compostos reciclats i s'han avaluat les característiques dels depòsits obtinguts. Els resultats van indicar que el sistema d'electrodiàlisi usant membranes d'intercanvi d'anions amb grups d'intercanvi de base forta ha pogut produir dissolucions tractades i un concentrat que conté els ions del bany. S'ha pogut afegir el concentrat al bany original per a compensar eventuals perdudes de l'arrossegament sense afectar la qualitat dels depòsits. Per tant, l'aplicació de l'electrodiàlisi va demostrar ser una alternativa viable per a la recuperació de l'aigua i de les matèries primeres de la dissolució avaluada, reduint la generació de residus líquids i estalviant els recursos naturals. / Scarazzato, T.

Spatial Function Estimation with Uncertain Sensor Locations / Spatial Function Estimation with Uncertain Sensor Locations

Ptáček, Martin January 2021 (has links)
Tato práce se zabývá úlohou odhadování prostorové funkce z hlediska regrese pomocí Gaussovských procesů (GPR) za současné nejistoty tréninkových pozic (pozic senzorů). Nejdříve je zde popsána teorie v pozadí GPR metody pracující se známými tréninkovými pozicemi. Tato teorie je poté aplikována při odvození výrazů prediktivní distribuce GPR v testovací pozici při uvážení nejistoty tréninkových pozic. Kvůli absenci analytického řešení těchto výrazů byly výrazy aproximovány pomocí metody Monte Carlo. U odvozené metody bylo demonstrováno zlepšení kvality odhadu prostorové funkce oproti standardnímu použití GPR metody a také oproti zjednodušenému řešení uvedenému v literatuře. Dále se práce zabývá možností použití metody GPR s nejistými tréninkovými pozicemi v~kombinaci s výrazy s dostupným analytickým řešením. Ukazuje se, že k dosažení těchto výrazů je třeba zavést značné předpoklady, což má od počátku za následek nepřesnost prediktivní distribuce. Také se ukazuje, že výsledná metoda používá standardní výrazy GPR v~kombinaci s upravenou kovarianční funkcí. Simulace dokazují, že tato metoda produkuje velmi podobné odhady jako základní GPR metoda uvažující známé tréninkové pozice. Na druhou stranu prediktivní variance (nejistota odhadu) je u této metody zvýšena, což je žádaný efekt uvážení nejistoty tréninkových pozic.

Sušovský, Tomáš January 2019 (has links)
This thesis focuses on design and implementation of a tool for automated generation of test inputs for a specified program trace. The aim of the thesis is to make development of testing suites (complying a given advanced coverage criteria) easier and more effective. These kinds of test suites are used in critical applications with code base written in low-level languages like C/C++ with strict restrictions applied. The tool investigates a program model and what conditions must be met to execute program in a way following provided trace. The tool uses advanced SMT-solver tool (software tool specialized for solving satisfiability problem) for generating fitting values. LLVM compiler framework libraries are used for modelling a program. Z3 library is used as a SMT-solver backend. This thesis brings results in architectural and implementation design of a tool capable of test inputs generation based on program analysis and provided program trace to cover.

Active Learning in the Sensorimotor Loop

Martius, Georg 20 October 2017 (has links)
In this thesis we study a novel approach to on-line learning of artificial neural networks, called backward modelling, and apply it to active learning in the sensorimotor loop. At first the mathematic foundations of this approach are elaborated. We observe effects like spontaneous symmetry breaking, response increasing, and generalisation improvement at a theoretical level. We then justify the theory with experimental results on some synthetic problems, in order to understand the phenomena clearly. Finally we consider a simple robot with an adaptive world model. In the case the controller of the robot is just covering a sub-space of the actuator space we realise degenerated world representations in the world model with passive learning and standard learning algorithms. We show that backward modelling and active learning point out degeneracies in the world model and correct them with direct exploration. A special kind of active learning evolves from the use of backward modelling which directly queries patterns on the fly. Additionally, different strategies are investigated in order to control the interplay of controller based and active learning based behaviour.
