Yes / In recent times two or more desalination processes have been combined to form integrated systems that have been widely used to resolve the limitations of individual processes as well as producing high performance systems. In this regard, a simple integrated system of the Multi Effect Distillation (MED)/Thermal Vapour Compression (TVC) and Permeate Reprocessing Reverse Osmosis (PRRO) process was developed by the same authors and confirmed its validity after a comparison study against other developed configurations. However, this design has a considerable amount of retentate flowrate and low productivity. To resolve this issue, two novel designs of MED and double reverse osmosis (RO) processes including Permeate and Retentate Reprocessing designs (PRRP and RRRO) are developed and modelled in this paper. To systematically assess the consistency of the presented designs, the performance indicators of the novel designs are compared against previous simple designs of MED and PRRO processes at a specified set of operating conditions. Results show the superiority of the integrated MED and double permeate reprocessing design. This has specifically achieved both economic and environmental advantages where total productivity is increased by around 9% and total retentate flowrate (disposed to water bodies) is reduced by 5% with a marginally reduced energy consumption.

Les technologies mobiles terrestre et satellite sont naturellement complémentaires. Les réseaux cellulaires terrestres sont adaptés aux villes où la densité d'utilisateurs est maximale mais perdent leur rentabilité dans les zones peu peuplées. A l'inverse, les systèmes mobile satellite permettent de couvrir de vastes zones à moindre coût mais n'assurent pas la couverture dans les zones urbaines car le signal est bloqué par les constructions. En les combinant pour assurer la couverture en ville par le réseau terrestre et dans les zones moins denses avec le satellite, on obtient un système à la couverture totale pour un coût optimal. Nous appelons un tel système intégrant une composante satellite et une composante terrestres un "système intégré" satellite/terrestre. Nul doute que d'ici quelques années, le rêve de la communauté satellite de rendre tous les terminaux mobiles capables de se connecter à un satellite sera accessible. Le satellite pourra ainsi être vu par les utilisateurs de terminaux portables comme une énième technologie d'accès à un système "intégré", aux côtés du Bluetooth, du Wifi et des technologies cellulaires (GSM, UMTS, LTE). La réutilisation du spectre satellite par les systèmes terrestres est un facteur déterminant dans le succès de cette intégration car elle permet de justifier les investissements dans le système satellite qui ne peut être rentabilisé par les abonnements seuls. Toutefois sa mise en œuvre pose de nombreux problèmes : règlementaires, commerciaux et bien entendu techniques. Cette thèse apporte des solutions sur ce dernier point et j'espère qu'elle contribuera ainsi à rendre possible ce rêve d'intégration. Nous avons adopté une approche descendante du problème du partage de spectre dans les systèmes mobiles satellite-terrestre. Nous avons tout d'abord établi une synthèse sur les aspects recouverts par l'intégration des systèmes mobiles satellite et terrestre. Nous avons ensuite dressé l'état de l'art sur la problématique de la réutilisation du spectre satellite par les systèmes terrestres, que nous avons complété par nos analyses. Nous avons décidé dans cette thèse de nous focaliser sur un des problèmes majeurs soulevés par cette réutilisation : les interférences co-fréquence du système terrestre sur le lien montant satellite. A partir de l'analyse d'une solution de partage statique de spectre par coordination des plans de fréquence (principe de zone d'exclusion), nous avons élaboré puis analysé les performances de mécanismes innovants d'allocation de ressources dans le système terrestre qui permettent de réduire de façon importante les interférences. De plus, nous proposons une méthode pour garantir au système satellite que les interférences subies sur son lien montant soient inférieures à une valeur limite. Enfin, nous définissons une architecture et les mécanismes associés qui permettent l'implantation des solutions proposées dans un système satellite-terrestre fondé sur la technologie LTE. L'étude du sujet de partage de spectre dans les systèmes mobiles satellite-terrestre est relativement nouvelle et cette thèse constitue donc un travail novateur important qui pourra être utilisé comme base à de futurs travaux. / Terrestrial and satellite mobile technologies are naturally complementary. Terrestrial cellular systems are adapted to urban areas where the user density is maximal but their cost-effectiveness is much lower in sparsely populated areas. On the contrary, mobile satellite systems cover large zones at a relatively low cost but they cannot ensure coverage in urban areas because of signal blockage due to buildings. By combining both systems for ensuring coverage in cities with terrestrial networks and in less dense areas with the satellite, we obtain a system with complete coverage for an optimal cost. Such a system is called mobile terrestrial and satellite "integrated system". It is likely that in a few years, the dream of enabling satellite connectivity on all mobile terminals will be within reach. The satellite will then be perceived for mobile terminal users as an additional access technology to an "integrated network" comparable to Wifi, Bluetooth or cellular technologies (GSM, UMTS, LTE). The spectrum reuse by terrestrial systems is a key for the success of this integration because it justifies part of the investments in the satellite systems that cannot be supported by user subscriptions only. However, implementation of spectrum sharing generates many issues: regulatory, commercial and obviously technical. This thesis brings answers on the latter and I hope it will contribute to make this dream of integration become reality. We used a descending approach of the issue of spectrum sharing in terrestrial and satellite mobile systems. First, we establish a synthesis of all the aspects covered by the integration of mobile satellite and terrestrial systems. Then, we made the state of the art on the issue of satellite spectrum reuse by terrestrial systems and we completed it with our analysis. We decided to focus our work on one of the major issues raised by this reuse: co-frequency interference generated by the terrestrial system on the satellite uplink. From the analysis of a solution proposing a static spectrum sharing by coordination of frequency plans (the exclusion zone principle), we elaborated and analyzed performances of innovative mechanisms of resources allocation in the terrestrial system that allows to reduce significantly the interferences. Moreover, we proposed a method for guaranteeing to the satellite system that interferences from the terrestrial system will not exceed a given threshold. At last, we define an architecture and the associated mechanism that allow the implementation of our solution in an integrated terrestrial-satellite systems based on LTE technology. The study of spectrum sharing in terrestrial-satellite mobile systems is rather new and this thesis represents an innovative work that may serve as a basis for future studies on this issue.

A Lei n˚. 12.435, de 6 de julho de 2011, instituiu o Sistema Único de Assistência Social (SUAS) no Brasil e é considerada um marco na Política de Assistência Social visto incluir, dentre os objetivos de gestão, a implementação da Gestão do Trabalho e a Educação Permanente. O interesse em realizar estudo de caso sobre a Gestão do Trabalho no âmbito do SUAS no município de Varginha, MG surgiu a fim de avaliar se os seus princípios se faziam presentes na operacionalização desta política em âmbito local. Para tanto, foi realizada revisão bibliográfica, visitas aos campos de pesquisa, que se constituíram nos cinco Centros de Referência de Assistência Social e ao Centro de Referência Especializado de Assistência Social e realização de entrevistas semi-estruturadas com os gestores e executores desta política. Foram levantados dados sobre a composição das equipes de referência; Analisadas a percepção, o discurso e a prática do Poder Público municipal em relação à Gestão do Trabalho e avaliada, junto ao Plano Municipal de Assistência Social (PMAS), a existência de planejamento de ações e mecanismos que visassem o fortalecimento da sua execução. Quanto à caracterização da política, os dados colhidos apontaram que o número de CRAS, CREAS e profissionais é insuficiente. Também ficou constatada a inexistência de concurso público específico, a ocorrência de readaptações de profissionais, a falta de experiência e conhecimentos necessários à área, além da predominância da terceirização dos profissionais de nível superior. Tudo isso contribui para o enfraquecimento da categoria “Trabalhadores do SUAS” e demonstra a necessidade de investimento na Gestão do Trabalho. Com relação à percepção e ao discurso, verificou-se que existe consciência sobre a incompletude das equipes e, assim, da impossibilidade do atendimento total da população. Enquanto os gestores apontaram a escassez de recursos para completá-las, os profissionais de nível superior elencaram falta de interesse ou vontade política, aliada ao não reconhecimento da Assistência Social como Política Pública. Adequação de espaços, contratação de pessoal e implantação do processo de capacitação foram indicadas. A prática revela que não são destinados recursos financeiros específicos à Gestão do Trabalho, inexiste setor responsável por sua operacionalização e nunca se realizou diagnóstico sobre essa questão; Os profissionais não contam com Plano Municipal de Capacitação, tampouco com Plano de Carreira, Cargos e Salários. Evidenciou-se carência de planejamento em relação à inserção de profissionais nos equipamentos públicos. A elaboração do PMAS ocorreu em processo participativo entre gestores e trabalhadores e utilizou informações oriundas do Diagnóstico Social (2013). A elaboração da Política Municipal de Capacitação e complementação das equipes, através da realização de concurso específico, foram apontadas, mas importantes ações não foram contempladas. Diante do exposto, verifica-se que a Gestão do Trabalho no âmbito do SUAS em Varginha é parcial e incipiente. Contudo, o Poder Público demonstrou consciência de que para a execução do SUAS, as orientações e normativas deverão ser efetivadas. Desta forma, será necessário o reconhecimento da sua importância para a prestação dos serviços e para que mudanças ocorram, deverão ser considerados o contexto histórico, político e orçamentário da política. / The law n˚. 12,435 from 6th July 2011 that set up the Unified System for Social Assistance (SUAS) is considered a milestone in policy making for Social Assistance in Brazil due to the fact that it includes in its objectives the implementation of Work Force Management and Permanent Education. The interest to explore more about Work Force Management within the SUAS in the town of Varginha, MG was to evaluate if its principles were present and rooted in the operational aspects of this policy in the town. In order to do this, it was taken extensive bibliography review; field visits of all five Social Assistance Reference Centers as well as the Specialised Reference Centre for Social Assistance. Semi-structured interviews with the management and with those who implement the policies were carried out. It was aimed at understanding the composition of the specialised teams; to analyse its perception, the rhetoric and the actions of the local government towards ‘Work force Management’ and to verify if the Local Plan for Social Assistance (PMAS) has in its content and execution actions and mechanism that contribute to its strengthening. In regards to the characteristics of this policy, the data shows that the numbers of CRAS, CREAS and professionals are not enough. It was also established that there is not specific recruitment for the area; many of its work force comes from other fields; there is a lack of experience and understanding for this area as well as outsourcing of specialised professionals with degrees in the field. All of this contributes to the weakening of the category of the ‘Workers in the SUAS’ and demonstrate the need for investment in the Work Force Management. In the interviewees’ perception and rhetoric, they acknowledge the teams are not completed and, therefore, they cannot meet all demand. While the management pointed out the lack of resources to met demand, the specialised professionals pointed out the lack of commitment and interest from the politicians to recognise Social Assistance as part of the Public Policy. Improvisation of spaces, recruitment of personnel and implementation of a process for permanent education were identified. The practice shows that there is not specific financial resources aimed at Work Force Management; there is not a department responsible for its operation and it has never been carried out any diagnosis of its performance. The professionals do not have a Local Plan for Development neither a Carrier Plan with well defined structure and wages. There is a gap in planning regards the access of these professionals to the public machinery and structure. The making up of the PMAS was in a participative way between management and workers and it was used information from the 2013 Social Diagnosis Study. The institution of the Local Policy for Development and to fulfill all teams through proper public entrance exams were point out but other important tasks were not completed. For all the facts it was confirmed that the Work Force management within SUAS in Varginha is partial and on its early stages. Nevertheless the public policy-makers acknowledges that to proper functioning the SUAS the suggestions and norms must be put in place. In this way, it is necessary to acknowledge of its importance to deliver public services and for changes to happen it is needed to take into consideration the historic context as well the political and budgetary policies.

In this sense, integrated crop-livestock systems have been characterized by different dynamics compared to conventional crops systems, mainly because of the more efficient use of inputs due to high nutrient stored in the soil. The no-tillage (NT) associated with integrated crop-livestock (ICL) has been an alternative for intensification of soil use in Southern Brazil. In this issue, there are a lot of farmers have been cropped maize for silage production in the summer and annual ryegrass for various purposes (cover crop and animal feed). The maize due its yield potential, chemical composition and nutritional value, among other factors, constitutes one of the most important cropped and consumed cereal in the world and, moreover, this crop can be used for market manufacturing animal feed and human food. In this work were (i) evaluate the effects of liming on soil management systems (conventional tillage – CT, minimum tillage – MT, no-tillage – NT, and chiseled no-tillage – CNT) about the accumulated nutrients in maize aerial part; (ii) evaluated the dry matter (DM) and silage yields taking into consideration the previous crop annual ryegrass for different uses (cover crop – C, grazing – G, and silage – S) during the winter. The experiment was carried out Field Demonstration and Experimental (CDE) of the ABC Foundation, in the municipality of Castro-PR, in a clayey Haplohumox. The experimental design was a randomized complete block with split plots and four replications. In main plots (10 x 30 m), four systems of soil management (CT, MT, NT and CNT) was studied. In subplots (10 x 10 m), the annual ryegrass was cropped for different purposes (C, G and S). The intensification of soil use due pasture or silage production during the winter cannot change macronutrient inputs in systems of soil tillage under high concentration of organic matter and acidity controlled. This can be state if the winter pasture to be adequately managed. The high DM and macronutrients accumulated in aerial part of maize show the ability of annual ryegrass for nutrient recycling on the systems of production with different tillage and conditions of lime reactivity. / Pesquisas vêm sendo direcionadas no sentido de aprimorar a eficiência de utilização de nutrientes pelas plantas, evitar a degradação dos recursos ambientais, aumentar o rendimento das culturas e maximizar a lucratividade no sistema de produção agrícola. Nesse sentido, os sistemas integrados de produção têm sido caracterizados por dinâmica diferenciada em relação aos cultivos isolados, principalmente por apresentarem maior eficiência na utilização dos insumos. O sistema plantio direto (SPD), aliado à integração lavoura-pecuária (ILP) tem se destacado como uma das alternativas para a produção mais intensiva e sustentável de alimentos no Sul do Brasil. Nesse caso, o milho tem sido cultivado em sucessão ao azevém anual que pode ser destinado na forma de pastejo e/ou silagem pré-secada consumida pelos animais e também como cobertura do solo. O milho por seu potencial produtivo, sua composição química e seu valor nutritivo, entre outros fatores, constituí em um dos mais importantes cereais cultivados e consumidos no mundo, assumindo grande importância em âmbito mundial devido a suas inúmeras finalidades, como atender ao mercado de fabricação de ração animal e alimentação humana. Os objetivos deste trabalho foram: (i) avaliar os efeitos da calagem em sistemas de manejo do solo (sistema convencional – SC, cultivo mínimo – CM, sistema plantio direto – SPD, e SPD com subsolagem – SPD+S) sobre o acúmulo de macronutrientes na parte aérea do milho; (ii) avaliar o rendimento de massa seca/silagem, decorrente de diferentes formas de uso (planta de cobertura do solo, pastejo animal e produção de silagem) do azevém anual durante o inverno. O experimento foi instalado no Campo Demonstrativo e Experimental (CDE) da Fundação ABC, no município de Castro, PR, em um solo Latossolo Bruno argiloso. O delineamento experimental utilizado foi o de blocos completos casualizados, com parcelas subdivididas e quatro repetições. Nas parcelas (10 x 30 m) foram estudados quatro sistemas de manejo do solo (SC, CM, SPD e SPD+S). Nas subparcelas (10 x 10 m) foram estudadas três formas de uso do azevém anual (cobertura, pastejo e silagem). A intensificação de uso do azevém anual mediante pastejo ou silagem pré-secada, desde que leve em consideração os critérios de altura (para pastejo/corte e resíduo) e nutricionais (com base na exportação e rendimento de massa seca) não alteram os aportes dos macronutrientes em sistemas de preparo de solo com alto teor de MO e acidez corrigida. Os altos rendimentos de MS e acúmulos de macronutrientes na parte aérea do milho evidenciam a capacidade do azevém anual proporcionar a reciclagem de nutrientes no sistema de produção, independentemente do manejo de solo adotado e condições de reatividade do calcário.

Developments in electric technologies have the potential to increase the efficiency and performance of commercial aircraft. However, without proper architecture innovation, technology developments at the subsystem level are not sufficient to ensure successful integration. Adaptations to existing architectures work well when trades are made strictly between equivalent systems which fulfill and induce the same functional requirements. However, this approach does not provide the architect with adequate flexibility to integrate technologies with differing functional and physical interfaces. Architecture redefinition is required for proper implementation of non-traditional and innovative architectural elements. A function-based process for innovative architecture design was developed to provide flexibility in the definition of candidate architectural concepts. Tools and methods were developed which facilitate the definition and exploration of a function-based architectural design space. These include functional decomposition, functional induction, dynamic morphology, adaptive functional mapping, reconfigurable mission definition, and concept level system installation. The Architecture Design Environment (ADEN) was built to integrate these tools and to facilitate the definition of physics-based models in evaluating the performance of candidate architectures. Using functions as the foundation of this process assists in mitigating assumptions which traditionally govern architecture structures and offers a promising approach to architecting through flexible conceptualization and integration. This toolset provides the framework wherein knowledge from conceptual, preliminary, and detailed design efforts can be linked in the definition of revolutionary architectures.

Despite the productive and environmental advantages of the iLP systems and the conditions that make them technically feasible, the evaluation of their economic viability is fundamental for the implementation, consolidation and expansion of this modality of productive arrangement. The objective of this study is to evaluate under what technical and market conditions an iLP system becomes economically viable or ceases to be. In order to carry out such analysis, the analysis started with a representative (hypothetical) farm located in the Brazilian Savanna biome. The assessment of economic viability was based on the analysis of the Discounted Cash Flow of this farm and considered the 2016 economic and financial indicators as the base scenario. Based on that scenario, the study also evaluated how the economic viability of an iLP project changes from shocks on key variables. Among the results, it is noteworthy that, although the iLP system has proved to be economically profitable in most of the simulated scenarios, cyclical changes decisively affect the economic viability of the project. / Sob quais condições técnicas e de mercado um sistema de integração lavoura-pecuária (iLP) se torna economicamente viável no Cerrado? Em que pese as vantagens produtivas e ambientais dos sistemas iLP e as condições que os tornam tecnicamente factíveis, a avaliação de sua viabilidade econômica é fundamental para a implementação, consolidação e expansão dessa modalidade de arranjo produtivo. O objetivo dessa dissertação é avaliar sob quais condições técnicas e de mercado um sistema iLP se torna ou deixa de ser economicamente viável. Para realizar tal análise, partiu-se de uma propriedade rural representativa (hipotética) localizada no bioma Cerrado. A avaliação da viabilidade econômica se deu por meio da análise do Fluxo de Caixa Descontado dessa propriedade, considerando como cenário referencial os indicadores econômico-financeiros de 2016 (dados secundários). A partir desse cenário base e dando choques na principais variáveis do sistema, foram simulados cenários alternativos de forma a identificar sob quais condições o projeto se torna ou deixa de ser economicamente viável. Entre os resultados encontrados, destaca-se que, embora o sistema iLP tenha se mostrado economicamente rentável na maioria dos cenários simulados, alterações conjunturais afetam de forma decisiva a viabilidade econômica do projeto.
