The promotion of science & technology and the creation of an enabling environment for countries innovation systems has been a growing worldwide trend in developed countries, with 21 out of 30 member countries of the Organisation for Economic Co-operation and Development (OECD) currently utilising some form of tax incentive program aimed at encouraging investment in research and development (R&D) by private industry. 1 Encouraging R&D and associated innovation is generally seen as an effective tool in advancing science and technology, which in turn leads to the creation of new products and services, an increase in international competitiveness of local business, direct foreign investment and social spin-offs in the form of increased employment and economic growth? R&D is, however, expensive and involves high levels of technical risk, with the costs and risk involved often outweighing the potential profit. Consequently, many businesses choose not to perform R&D, which has resulted in governments of most developed countries having implemented various incentives to encourage private business to undertake R&D. These incentives can take the form of either direct incentives (grants, soft loans, subsidies etc) or indirect incentives (such as tax incentives). Tax incentives effectively subsidise the costs of R&D, making it a more attractive and profitable alternative for business. Developed countries, including: the United States of America (US), the United Kingdom (UK), Japan, China, Canada and Australia have all adopted a combination of both direct and indirect incentives, with various tax incentive measures receiving much attention in the last 2 decades. In South Africa the legislation providing for R&D tax incentives has been substantially amended in recent years through a number of Taxation Amendment Acts,] culminating in the enactment of s lID of the Income Tax Act 58 of 1962 (the Act). The aim of this dissertation is to critically examine the current South Afi'ican tax incentive scheme as contained in sliD, focusing on the eligibility requirements of that incentive. In addition, the dissertation will highlight design features and characteristics of the incentive, particularly in respect of its generosity, predictability, simplicity, administration and targeting. 4 The design and characteristics of the South African incentive is then compared to those of three different countries: the UK, Australia and Canada.s Based on the analysis and comparison, certain lessons are identified for South Africa6 and various opinions are advanced on the effectiveness of the current structure and whether particular aspects of it could be improved going forward. / Thesis (LL.M.)-Unversity of KwaZulu-Natal, Durban, 2010.

Cette thèse porte sur les capacités d'extraction d'une mousse déposée sur un support poreux dans le but d'y déloger un contaminant ayant imprégné la porosité. Nous avons donc considéré l'imprégnation forcée de fluides dans un pore unique, étudiée pour deux cas particuliers : (i) lors de l'impact d'une goutte de liquide à l'aplomb d'un pore unique vertical cette situation visant à modéliser l'imprégnation du poreux par le contaminant, et (ii) lors de l'aspiration d'une mou sse liquide à travers le pore qui illustre la compétition d'aspiration entre la mousse et le poreux. Dans chaque cas, le diamètre du pore est inférieur à celui des gouttes ou des bulles.Pour le premier cas, nous nous sommes intéressés au volume et à la profondeur d'imprégnation pour des surfaces hydrophiles et hydrophobes. Nous établissons les diagrammes d'imprégnation en fonction du diamètre du pore et de la vitesse d'impact et un travail de modélisation nous permet de déterminer les limites entre les différentes régions de ces digrammes.Pour le second cas, nous montrons que lors de l'aspiration, la mousse entre dans le pore uniquement dans un domaine bien déterminé dans le diagramme fraction liquide, rapport de taille pore/bulle et débit d'aspiration. En dehors de ce domaine, l'aspiration peut faire entrer soit le gaz seul, soit le liquide seul. La encore, un travail de modélisation nous permet de prédire les limites des différentes zones du diagramme. Dans une dernière partie, nous revenons à un problème pratique d'imprégnation sur support textile et quantifions les capacités d'extraction d'une mousse dans cette configuration dans le but d'y déloger un contaminant

Attempts to identify information as an asset has led to an increased awareness of the role of information in enhancing organisational performance. Central to this role is the identification of attributes of information assets which include quality, utility, productivity, effectiveness and financial and economic aspects. Measurement of attributes of information as an asset may provide an identifiable link between information management and improved business performance. Identifying attributes of information assets that are recognised and valued by senior managers in today's information-intensive UK organisations is a key step in developing evidence for a link between information management and organisational performance. The research study engaged with a range of stakeholders in the information as an asset domain, including: senior British information managers, senior executives and managers and internationally-active information professionals and academics. Open-ended guided interviews were conducted with stakeholders. Four case studies in information-intensive UK organisations formed the major data collection strategy. Findings highlighted the importance of customer information assets. The most important attribute identified was quality. Information assets and their attributes were linked to competitive advantage with customer involvement and management attention being the key issues identified. A grounded theory of information assets that takes competitive advantage as its core category, is proposed.

In this context, two main goals, the stratigraphic and the structural analysis, had guided the research. For this purpose, it was used the 3D seismic volume and eight wells located in the study area and adjacencies. The stratigraphic analysis of the Valanginian-Barremian interval was carried through in two distinct phases, 1D and 2D, in which the basic concepts of the sequence stratigraphy had been adapted. In these phases, the individual analysis of each well and the correlation between them, allowed to recognize the main lithofacies, to interpret the effective depositional systems and to identify the genetic units and key-surfaces of chronostratigraphic character. The analyzed lithofacies are represented predominantly by conglomerates, sandstones, siltites and shales, with carbonate rocks and marls occurring subordinately. According to these lithofacies associations, it is possible to interpret the following depositional systems: alluvial fan, fluvio-deltaic and lacustrine depositional systems. The alluvial fan system is mainly composed by conglomerates deposits, which had developed, preferentially in the south portion of the area, being directly associated to Carnaubais fault system. The fluvial-deltaic system, in turn, was mainly developed in the northwest portion of the area, at the flexural edge, being characterized by coarse sandstones with shales and siltites intercalated. On the other hand, the lacustrine system, the most dominant one in the study area, is formed mainly by shales that could occur intercalated with thin layers of fine to very fine sandstones, interpreted as turbidite deposits. The recognized sequence stratigraphy units in the wells are represented by parasequence sets, systems tracts and depositional sequences. The parasequence sets, which are progradational or retrogradational, had been grouped and related to the systems tracts. The predominance of the progradation parasequence sets (general trend with coarsening-upward) characterizes the Regressive Systems Tract, while the occurrence, more frequently, of the retrogradation parasequence sets (general trend with finning-upward) represents the Transgressive System Tract. In the seismic stratigraphic analysis, the lithofacies described in the wells had been related to chaotic, progradational and parallel/subparallel seismic facies, which are associated, frequently, to the alluvial fans, fluvial-deltaic and lacustrine depositional systems, respectively. In this analysis, it was possible to recognize fifteen seismic horizons that correspond to sequence boundaries and to maximum flooding surfaces, which separates Transgressive to Regressive systems tracts. The recognition of transgressive-regressive cycles allowed to identify nine, possibly, 3a order deposicional sequences, related to the tectonic-sedimentary cycles. The structural analysis, in turn, was done at Baixo Vermelho seismic volume, which shows, clearly, the structural complexity printed in the area, mainly related to Carnaubais fault system, acting as an important fault system of the rift edge. This fault system is characterized by a main arrangement of normal faults with trend NE-SO, where Carnaubais Fault represents the maximum expression of these lineations. Carnaubais Fault corresponds to a fault with typically listric geometry, with general trend N70?E, dipping to northwest. It is observed, throughout all the seismic volume, with variations in its surface, which had conditioned, in its evolutive stages, the formation of innumerable structural features that normally are identified in Pendencia Formation. In this unit, part of these features is related to the formation of longitudinal foldings (rollover structures and distentional folding associated), originated by the displacement of the main fault plan, propitiating variations in geometry and thickness of the adjacent layers, which had been deposited at the same time. Other structural features are related to the secondary faultings, which could be synthetic or antithetic to Carnaubais Fault. In a general way, these faults have limited lateral continuity, with listric planar format and, apparently, they play the role of the accomodation of the distentional deformation printed in the area. Thus, the interaction between the stratigraphic and structural analysis, based on an excellent quality of the used data, allowed to get one better agreement on the tectonicsedimentary evolution of the Valanginian-Barremian interval (Pend?ncia Formation) in the studied area / A ?rea de Baixo Vermelho, localizada na por??o norte do Graben de Umbuzeiro (Bacia Potiguar emersa), representa um exemplo t?pico de uma bacia do tipo rifte, caracterizada, em subsuperf?cie, pela seq??ncia sedimentar rifte, correlata ? Forma??o Pend?ncia (Valanginiano-Barremiano), e pelo Sistema de Falhas de Carnaubais. Dentro deste contexto, duas abordagens principais nortearam o estudo, a estratigr?fica e a estrutural, em que se lan?ou m?o da interpreta??o do volume s?smico 3D de Baixo Vermelho e de oito po?os explorat?rios da ?rea e adjac?ncias. A an?lise estratigr?fica do intervalo do Valanginiano ao Barremiano foi realizada em duas fases distintas, 1D e 2D, nas quais foram adaptados os conceitos b?sicos da estratigrafia de seq??ncias. Nestas fases, a an?lise individual de cada po?o e a correla??o entre os mesmos permitiu reconhecer as principais litof?cies presentes, interpretar os sistemas deposicionais vigentes e identificar as unidades gen?ticas e as superf?cies-chave de car?ter cronoestratigr?fico. As litof?cies analisadas constituem, predominantemente, conglomerados, arenitos, siltitos e folhelhos, ocorrendo, ainda, de forma subordinada, rochas carbon?ticas e margas. Com base nas associa??es destas litof?cies foram interpretados os sistemas deposicionais de leque aluvial, fl?vio-deltaico e lacustre. O sistema de leque aluvial ? composto, principalmente, por dep?sitos conglomer?ticos, os quais se desenvolveram, principalmente, na por??o sul da ?rea, estando diretamente associados ao Sistema de Falhas de Carnaubais. O sistema fl?viodeltaico, por sua vez, foi desencadeado, preferencialmente, na por??o noroeste da ?rea, na margem flexural, sendo caracterizado por arenitos grossos a finos intercalados a folhelhos e siltitos. Em contrapartida, o sistema lacustre, o mais dominante na ?rea investigada, ? formado principalmente por folhelhos que ocorrem, por vezes, intercalados a delgadas camadas de arenitos finos a muito finos, interpretados como dep?sitos turbid?ticos. As unidades da estratigrafia de seq??ncias reconhecidas nos po?os est?o representadas pelos conjuntos de parasseq??ncias, tratos de sistemas e seq??ncias deposicionais. Os conjuntos de parasseq??ncias, ora progradacionais, ora retrogradacionais, foram agrupados e relacionados aos tratos de sistemas. A predomin?ncia dos conjuntos de parassequ?ncias progradacionais (trend geral com engrossamento textural para o topo) caracteriza o Trato de Sistemas Regressivo, ao passo que a ocorr?ncia, com maior freq??ncia, dos conjuntos de parassequ?ncias retrogradacionais (trend geral com afinamento textural para o topo) representam o Trato de Sistemas Transgressivo. Na an?lise sismoestratigr?fica, as litof?cies descritas nos po?os foram relacionadas ?s sismof?cies ca?tica, progradacional e paralela/subparalela, as quais se associam, freq?entemente, aos sistemas de leques aluviais, fl?vio-deltaico e lacustre, respectivamente. Nesta an?lise foram mapeados quinze horizontes s?smicos que correspondem aos limites de seq??ncias deposicionais e ?s superf?cies de inunda??o m?xima, que separam o trato de sistemas transgressivo do regressivo. O reconhecimento de ciclos transgressivo-regressivo permitiu identificar nove seq??ncias deposicionais, possivelmente de 3a ordem, relacionadas a ciclos tectono-sedimentares. A an?lise estrutural, por sua vez, foi realizada no volume s?smico de Baixo Vermelho, que mostra, com clareza, a complexidade estrutural impressa na ?rea, relacionada, principalmente, ao Sistema de Falhas de Carnaubais, que atua como um importante sistema de falhas de borda de rifte. Este sistema de falhas ? caracterizado por um arranjo principal de falhas normais NE-SO, em que a Falha de Carnaubais representa a express?o m?xima destes lineamentos. A Falha de Carnaubais corresponde a uma falha com geometria tipicamente l?strica, direcionada segundo o trend geral N70?E, mergulhando para noroeste. Apresenta-se, ao longo de todo o volume s?smico, com varia??es em sua superf?cie, as quais condicionaram, em seus est?gios evolutivos, a forma??o de in?meras fei??es estruturais, que s?o comumente identificadas na Forma??o Pend?ncia. Nesta unidade, parte das fei??es est? relacionada ? forma??o de dobramentos longitudinais (estrutura do tipo rollover e dobramentos distensionais associados), decorrentes do deslocamento do plano da falha principal, propiciando varia??es na geometria e espessura dos estratos adjacentes, os quais foram depositados sincronicamente. Outras fei??es estruturais est?o relacionadas a falhamentos secund?rios, tanto sint?ticos quanto antit?ticos ? Falha de Carnaubais. De uma maneira geral, estas falhas t?m continuidade lateral limitada, com formato planar a l?strico e, aparentemente, desempenham o papel de acomoda??o da deforma??o distensional imposta na ?rea. Assim, a intera??o entre as an?lises estratigr?fica e estrutural, alicer?ados pela excelente qualidade dos dados utilizados, permitiu obter um melhor entendimento sobre a evolu??o tectono-sedimentar do intervalo Valanginiano ao Barremiano (Forma??o Pend?ncia) na ?rea de estudo

No entanto h? uma necessidade urgente na diversifica??o da nossa matriz de forma que haja uma maior seguran?a para o consumidor em per?odos com escassez de chuva e, al?m disso, que essas varia??es na gera??o de energia el?trica se adaptem ?s discuss?es atuais referentes ? baixa emiss?o de carbono al?m de garantir uma maior preserva??o ambiental. Nesse contexto, surge a energia solar fotovoltaica que, al?m de possuir um grande potencial na produ??o de eletricidade oriunda de um recurso inesgot?vel ? o sol - ainda ? uma fonte energ?tica que contribui imensamente para a economia do pa?s devido ao seu elevado ?ndice de empregabilidade, com pouco mais de oito milh?es de empregos gerados no mundo somente no ano de 2016. Apesar de ainda representar a menor parcela na participa??o da matriz energ?tica el?trica nacional, a energia solar fotovoltaica come?a a mostrar sinais de for?a e potencial em crescimento no cen?rio nacional desde a resolu??o 482 de 2012, atualizada pela norma 687 de 2015 que, juntas, incentivam e criam oportunidades mais acess?veis para o consumidor/gerador de pequeno porte. Com base nos conceitos de mini e micro gera??o distribu?da, contidos nas normas supracitadas, o Instituto Federal do Rio Grande do Norte (IFRN) foi a primeira institui??o de ensino p?blica no Brasil a aderir ao sistema de compensa??o energ?tica regulamentado pela ANEEL e hoje j? conta com 14 usinas em opera??o onde quatro encontram-se em projeto de amplia??o e outras sete encontram-se em fase de instala??o. Uma dessas usinas situa-se no campus da cidade de Santa Cruz localizada na mesorregi?o do agreste potiguar. A mesma possui um sistema de micro gera??o fotovoltaica conectada ? rede com pot?ncia nominal de instala??o de 84kWp e ser? tema de discuss?o nesse trabalho. Essa disserta??o ter? como objetivo uma an?lise t?cnica (atrav?s das an?lises da produtividade do sistema, produtividade de refer?ncia, desempenho global - performance ratio) e econ?mica (an?lise pelo m?todo payback simples e descontado, Valor Presente L?quido ? VPL e a Taxa Interna de Retorno - TIR) do micro gerador fotovoltaico com a finalidade de verificar o funcionamento atual do sistema e compara-lo com outros sistemas. Al?m de verificar a viabilidade econ?mica da instala??o dentro do per?odo de vida ?til dos componentes do sistema fornecido pela empresa respons?vel pela instala??o que ? de 25 anos. / According to national research companies, the Brazilian electrical matrix is almost totally composed by hydroelectric energy, around 65%. However, it is necessary to change our matrix in a way that makes it more secure for the consumers in periods of draught. Moreover, these variations in the electric power generation have to be adapted to the discussions about low carbon emissions and environmental preservation. In this context, the photovoltaic solar energy drawn with an inexhaustible generation fount ? the sun - and great potential in producing electrical energy. Moreover, the photovoltaic solar energy plays a huge contribution to the Brazilian economy due to its high employability index, with more than eight million jobs created in the world in the year of 2016 alone. Despite representing the smallest participation in the national electrical matrix, the photovoltaic solar energy starts to show signs of power and potential in the national scenario since the resolution 482 of 2012, updated by the norm 687 of 2015 that, together, encourage and create opportunities more accessible to the small consumer/generator. According the concepts about mini and micro distributed generation, contained in the norms already cited, the Federal Institute of Rio Grande do Norte (IFRN) was the first Brazilian public institution of teaching to adhere to the system of electrical energy compensation of the ANEEL and today it counts with 14 plants in operation which four are in extension phase and other seven are in installation phase. One of these plants is located at the Santa Cruz Campus. This plant has a photovoltaic micro generation connected to the grid with installation nominal power of 84kWp and will be the subject of discussion of this master thesis. The target of this master thesis is to perform a technical analysis (through the analyses of system productivity, reference productivity, global performance ? performance ration) and economic analysis (simple and discounted payback, liquid present value ? VPL and intern return index ? TIR) of the photovoltaic micro generator in order to verify the actual operation system condition and compare it with other systems. In addition, this thesis will also verify the economic viability of the installation inside the 25 years? life period of the system components.

O local de estudo em quest?o, por ser uma ?rea militar protegida, encontra-se completamente livre de interfer?ncias humanas e sem nenhuma edifica??o em seu topo, fazendo com que as an?lises sejam representativas de condi??es naturais impostas aos taludes estudados. As atividades desenvolvidas durante a elabora??o desta disserta??o est?o agrupadas em quatro etapas: revis?o bibliogr?fica, trabalhos de campo, ensaios de laborat?rio e an?lise da estabilidade das fal?sias. Atrav?s de visitas realizadas na ?rea de estudo, foram colhidas informa??es necess?rias para a posterior obten??o dos perfis cr?ticos das fal?sias para an?lise de estabilidade. Foram observados que os perfis em geral n?o s?o ?ngremes, com a presen?a de incis?o basal em alguns trechos. Verificou-se nas an?lises que as tens?es de tra??o atuantes apresentam valores baixos. O principal mecanismo respons?vel por deflagrar os processos de instabilidade ? o aumento parcial da satura??o dos solos ocasionado pelas precipita??es pluviom?tricas, o que diminui sua resist?ncia e gera movimentos de massa. Pelos ensaios realizados observou-se que o intercepto de coes?o dos solos saturados ? em torno de 26% do valor obtido para os solos no teor de umidade natural. Contudo, os ?ngulos de atrito em ambos os casos sofrem inexpressivas varia??es. Concluiu-se que a presen?a da incis?o basal n?o apresentou efeitos significativos na redu??o da estabilidade nas configura??es analisadas pelos m?todos por Equil?brio-Limite, enquanto que pela an?lise de tens?es observa-se um aumento de tens?es de tra??o na face da se??o. O estudo da an?lise de estabilidade realizado neste trabalho representou efetivamente os tipos de ruptura observados nas fal?sias do litoral do Rio Grande do Norte, sendo bem mais coerentes que os obtidos pelos m?todos tradicionais. / This Dissertation treat of obtaining geotechnical properties of sediments of Barreiras Formation and the stability analysis of the cliffs located at the Barreira do Inferno Launches Center, Parnamirim, Rio Grande do Norte State. Coastal areas attracts great interest for the population in general, and developments in these regions are quite common, causing erosive processes to be studied in order to provide a better understanding of the factors influencing the Stability of the cliffs and consequently their safety. The study site in question, being a protected military area, is completely free of human interference and without any edification at its top, making the analysis representative of natural conditions imposed on the slopes studied. The activities developed during the elaboration of this dissertation are grouped in four stages: bibliographic revision, fieldwork, laboratory tests and stability analysis of the cliffs. Based on visits accomplished in situ, information was collected for the subsequent retrieval of the critical profiles of the cliffs for stability analysis. It was observed that the profiles in general aren?t steep, with the presence of basal incision in some areas. It was verified in analyzes that the tensile tensions acting are low. The main mechanism responsible for triggering the instability processes is the partial increase of soil saturation caused by rainfall, which decreases its resistance and generates mass movements. From the tests carried out, it was observed that the cohesion intercept of the saturated soils is around 26% of the obtained value in the natural moisture content. However, the angles of friction in both cases suffer inexpressive variations It was concluded that the presence of the basal incision had no significant effect on the reduction of stability in the configurations analyzed by the limit equilibrium methods, while stress analysis showed an increase in tensile stresses on the face of the section. The study of the stability analysis performed in this work effectively represented the types of rupture observed in the cliffs of the coast of Rio Grande do Norte, being more coherent than those obtained by traditional methods.

Algoritmos bioinspirados, baseados no comportamento de organismos, s?o adequados para problemas de otimiza??o e v?m sendo, recentemente, empregados para a sele??o de caracter?sticas em v?rios dom?nios de problemas. Nesta pesquisa, a vers?o bin?ria do algoritmo bioinspirado em col?nia artificial de abelhas ? aplicado na sele??o de caracter?sticas para detec??o de desvios vocais, com o intuito de determinar quais medidas ac?sticas baseadas na an?lise da quantifica??o de recorr?ncia s?o relevantes para a discrimina??o entre vozes saud?veis e vozes com desvios vocais (soprosidade, rugosidade e tens?o). Os resultados apontam que, de forma geral, houve uma redu??o na quantidade de caracter?sticas utilizadas na classifica??o, empregando-se o classificador K-NN, com taxas de acur?cia superiores a 86%, apresentando competitividade quando comparados com outras abordagens.
