Due to the long range capabilities and low energy consumption, Low-Power Wide Area Networks (LPWANs) are the ideal technologies to send small data occasionally. With their unique characteristics, LPWANs can be used in many applications and in di erent environments such as urban, rural and even indoor.

For this, three distinct scenarios are proposed and tested. The inclusion of LoRa in a multi-technology data gathering platform is the key objective of this dissertation. For this it is proposed: (1) an organization based in clusters of sensor nodes; (2) a Media Access Control (MAC) protocol to provide e cient communications through the LoRa technology; and nally, (3) a Connection Manager that is capable of managing the di erent available technologies in the sensor nodes and that is able to adapt its actions according to the acquired data type is proposed. The performed tests aim to perceive which type of parameters can in uence the performance of the overall proposed solution, as well as the advantages of a multi-technology approach in a data gathering platform.

Повний текст джерелаA partir del año 2020 se prevé que un nuevo paradigma de comunicación surja en la sociedad, debido a la aparición de nuevos servicios y la era del Internet de las cosas. El conjunto de requisitos impuesto por estas nuevas aplicaciones es muy amplio y diverso, y tiene como principal objetivo proporcionar conectividad de banda ancha y universal. En las últimas décadas, la comunidad científica ha estado trabajando en la definición de la 5G de redes móviles que brindará los mecanismos necesarios para garantizar estos requisitos. En este marco, se han identificado tres mecanismos clave para conseguir el necesario incremento de capacidad de la red: el aumento de la eficiencia espectral a través de, por ejemplo, el uso de tecnologías MIMO masivas, la utilización de mayores porciones del espectro en frecuencia y la densificación de la red mediante el despliegue de más estaciones base por área. Esta Tesis doctoral aborda la densificación como el principal mecanismo que permitirá la conectividad de banda ancha y universal requerida en la 5G, centrándose en el estudio de las Redes Ultra Densas o UDNs. En concreto, se analiza el conjunto de tecnologías habilitantes que pueden llevar a las UDNs a obtener su máxima eficiencia y prestaciones, incluyendo el uso de altas frecuencias para el aprovechamiento de mayores anchos de banda, la utilización de MIMO masivo con sistemas de antenas distribuidas y el uso de técnicas de reparto de recursos distribuidas para la coordinación de interferencias. En primer lugar, se analiza si existe un límite fundamental en la mejora de las prestaciones en relación a la densificación. Con este fin, las prestaciones de las UDNs se evalúan utilizando un modelo analítico de red unidimensional con BSs equiespaciadas, en el que la distancia entre BSs se disminuye hasta alcanzar el límite de densificación cuando ésta se aproxima a 0. Las tasas alcanzables en redes con distintas distancias entre BSs son analizadas, considerando distintos niveles de potencia disponible en la red y varios grados de cooperación entre celdas. Además, el comportamiento de las UDNs se estudia junto al uso masivo de antenas y la utilización de anchos de banda mayores. Más concretamente, las prestaciones de ciertas técnicas híbridas MIMO de precodificación y beamforming se examinan en la banda milimétrica. Por una parte, se analizan esquemas de beamforming en BSs con arquitectura híbrida en función de la disponibilidad de cadenas de radiofrecuencia en escenarios exteriores. Por otra parte, se evalúan las prestaciones de ciertos esquemas de precodificación híbrida en escenarios interiores, utilizando distintos despliegues y centrando la atención en los sistemas de antenas distribuidos o DAS. Además, se propone un algoritmo de precodificación híbrida específico para DAS, y se evalúan y comparan sus prestaciones con las de otros algoritmos de precodificación utilizados. Por último, se investiga el impacto en las prestaciones de ciertas limitaciones prácticas y deficiencias introducidas por el uso de dispositivos no ideales. Finalmente, el estudio de las UDNs se completa con el análisis de su principal limitación, el nivel creciente de interferencia en la red. Para ello, se propone un algoritmo de control de interferencias basado en la partición de recursos. Sus prestaciones son evaluadas y comparadas con las de otras técnicas de asignación de recursos. Tras este estudio, se puede afirmar que las UDNs tienen gran potencial para la consecución de los requisitos de la 5G. Sin embargo, sin el uso conjunto de mayores porciones del espectro, adecuadas técnicas de control de la interferencia y el uso masivo de antenas, las UDNs pueden convertirse en serios obstáculos para los operadores móviles. Los resultados de la evaluación de prestaciones de estas tecnologías confirman el gran aumento de la capacidad de las redes mediante el uso masivo de antenas y la introducción de mecanismos de I
A partir de l'any 2020 es preveu un nou paradigma de comunicació en la societat, degut a l'aparició de nous serveis i la era de la Internet de les coses. El conjunt de requeriments imposat per aquestes noves aplicacions és ampli i divers, i té com a principal objectiu proporcionar connectivitat universal i de banda ampla. En les últimes dècades, la comunitat científica ha estat treballant en la definició de la 5G, que proveirà els mecanismes necessaris per a garantir aquests exigents requeriments. En aquest marc, s'han identificat tres mecanismes claus per a aconseguir l'increment necessari en la capacitat: l'augment de l'eficiència espectral a través de, per exemple, l'ús de tecnologies MIMO massives, la utilització de majors porcions de l'espectre i la densificació mitjançant el desplegament de més estacions base per àrea. Aquesta Tesi aborda la densificació com a principal mecanisme que permetrà la connectivitat de banda ampla i universal requerida en la 5G, centrant-se en l' estudi de les xarxes ultra denses (UDNs). Concretament, el conjunt de tecnologies que poden dur a les UDNs a la seua màxima eficiència i prestacions és analitzat, incloent l'ús d'altes freqüències per a l'aprofitament de majors amplàries de banda, la utilització de MIMO massiu amb sistemes d'antenes distribuïdes i l'ús de tècniques distribuïdes de repartiment de recursos per a la coordinació de la interferència. En primer lloc, aquesta Tesi analitza si existeix un límit fonamental en les prestacions en relació a la densificació. Per això, les prestacions de les UDNs s'avaluen utilitzant un model analític unidimensional amb estacions base equidistants, en les quals la distància entre estacions base es redueix fins assolir el límit de densificació quan aquesta distància s'aproxima a 0. Les taxes assolibles en xarxes amb diferents distàncies entre estacions base s'analitzen considerant diferents nivells de potència i varis graus de cooperació entre cel·les. A més, el comportament de les UDNs s'estudia conjuntament amb l'ús massiu d'antenes i la utilització de majors amplàries de banda. Més concretament, les prestacions de certes tècniques híbrides MIMO de precodificació i beamforming s'examinen en la banda mil·limètrica. D'una banda, els esquemes de beamforming aplicats a estacions base amb arquitectures híbrides és analitzat amb disponibilitat limitada de cadenes de radiofreqüència a un escenari urbà dens. D'altra banda, s'avaluen les prestacions de certs esquemes de precodificació híbrida en escenaris d'interior, utilitzant diferents estratègies de desplegament i centrant l'atenció en els sistemes d' antenes distribuïdes (DAS). A més, es proposa un algoritme de precodificació híbrida distribuïda per a DAS, i s'avaluen i comparen les seues prestacions amb les de altres algoritmes. Per últim, s'investiga l'impacte de les limitacions pràctiques i altres deficiències introduïdes per l'ús de dispositius no ideals en les prestacions de tots els esquemes anteriors. Finalment, l' estudi de les UDNs es completa amb l'anàlisi de la seua principal limitació, el nivell creixent d'interferència entre cel·les. Per tractar aquest problema, es proposa un algoritme de control d'interferències basat en la partició de recursos. Les prestacions de l'algoritme proposat s'avaluen i comparen amb les d'altres tècniques d'assignació de recursos. Una vegada completat aquest estudi, es pot afirmar que les UDNs tenen un gran potencial per aconseguir els ambiciosos requeriments plantejats per a la 5G. Tanmateix, sense l'ús conjunt de majors amplàries de banda, apropiades tècniques de control de la interferència i l'ús massiu d'antenes, les UDNs poden convertir-se en seriosos obstacles per als operadors mòbils. Els resultats de l'avaluació de prestacions d' aquestes tecnologies confirmen el gran augment de la capacitat de les xarxes obtingut mitjançant l'ús massiu d'antenes i la introducci

Повний текст джерелаSince the beginning of the 21st century, terrestrial broadcasting systems have been blamed of an inefficient use of the allocated spectrum. To increase the spectral efficiency, digital television Standards Developing Organizations settled to develop the technical evolution of the first-generation DTT systems. Among others, a primary goal of next-generation DTT systems (DVB-T2 and ATSC 3.0) is to simultaneously provide TV services to mobile and fixed devices. The major drawback of this simultaneous delivery is the different requirement of each reception condition. To address these constraints different multiplexing techniques have been considered. While DVB-T2 fulfilled the simultaneous delivery of the two services by TDM, ATSC 3.0 adopted the LDM technology. LDM can outperform TDM and FDM by taking advantage of the UEP ratio, as both services, namely layers, utilize all the frequency and time resources with different power levels. At receiver side, two implementations are distinguished, according to the intended layer. Mobile receivers are only intended to obtain the upper layer, known as CL. In order not to increase their complexity compared to single layer receivers, the lower layer, known as EL is treated as an additional noise on the CL decoding. Fixed receivers, increase their complexity, as they should performed a SIC process on the CL for getting the EL. To limit the additional complexity of fixed receivers, the LDM layers in ATSC 3.0 are configured with different error correction capabilities, but share the rest of physical layer parameters, including the TIL, the PP, the FFT size, and the GI. This dissertation investigates advanced technologies to optimize the LDM performance. A demapping optimization for the two LDM layers is first proposed. A capacity increase is achieved by the proposed algorithm, which takes into account the underlying layer shape in the demapping process. Nevertheless, the number of Euclidean distances to be computed can be significantly increased, contributing to not only more complex fixed receivers, but also more complex mobile receivers. Next, the most suitable ATSC 3.0 pilot configuration for LDM is determined. Considering the two layers share the same PP a trade-off between pilot density (CL) and data overhead (EL) arises. From the performance results, it is recommended the use of a not very dense PP, as they have been already designed to cope with long echoes and high speeds. The optimum pilot amplitude depends on the channel estimator at receivers (e.g. the minimum amplitude is recommended for a Wiener implementation, while the maximum for a FFT implementation). The potential combination of LDM with three advanced technologies that have been adopted in ATSC 3.0 is also investigated: MultiRF technologies, distributed MISO schemes, and co-located MIMO schemes. The potential use cases, the transmitter and receiver implementations, and the performance gains of the joint configurations are studied for the two LDM layers. The additional constraints of combining LDM with the advanced technologies is considered admissible, as the greatest demands (e.g. a second receiving chain) are already contemplated in ATSC 3.0. Significant gains are found for the mobile layer at pedestrian reception conditions thanks to the frequency diversity provided by MultiRF technologies. The conjunction of LDM with distributed MISO schemes provides significant performance gains on SFNs for the fixed layer with Alamouti scheme. Last, considering the complexity in the mobile receivers and the CL performance, the recommended joint configuration is MISO in the CL and MIMO in the EL.
Des de començaments del segle XXI, els sistemes de radiodifusió terrestre han sigut culpats d'un ús ineficient de l'espectre assignat. Per a augmentar l'eficiència espectral, els organismes d'estandardització de TV digital van començar a desenvolupar l'evolució tècnica dels sistemes de TDT de primera generació. Entre altres, un dels objectius principals dels sistemes de TDT de pròxima generació (DVB-T2 i el ATSC 3.0) és proporcionar simultàniament serveis de TV a dispositius mòbils i fixos. El principal inconvenient d'aquest lliurament simultani són els diferents requisits de cada condició de recepció. Per a abordar aquestes limitacions, s'han considerat diferents tècniques de multiplexació. Mentre que DVB-T2 escomet el lliurament simultani dels dos serveis mitjançant TDM, ATSC 3.0 va adoptar la Multiplexació per Divisió en Capes (LDM). LDM pot superar a TDM i a FDM en aprofitar la relació de Protecció d'Error Desigual (UEP), ja que tots dos serveis, cridats capes, utilitzen tots els recursos de freqüència i temps amb diferents nivells de potència. En el costat del receptor, es distingeixen dues implementacions, d'acord amb la capa a decodificar. Els receptors mòbils solament estan destinats a obtenir la capa superior, coneguda com Core Layer (CL). Per a no augmentar la seua complexitat en comparació amb els receptors de capa única, la capa inferior, coneguda com Enhanced Layer (EL), és tractada com un soroll addicional en la decodificació. Els receptors fixos augmenten la seua complexitat, ja que han de realitzar un procés de Cancel·lació d'Interferència (SIC) sobre la CL per a obtenir l'EL. Per a limitar la complexitat addicional dels receptors fixos, les capes de LDM en ATSC 3.0 estan configurades amb diferents capacitats de correcció, però comparteixen la resta de blocs de la capa física, inclòs el TIL, el PP, la grandària de FFT i el GI. Aquesta dissertació investiga tecnologies avançades per a optimitzar el rendiment de LDM. Primer es proposa una optimització del procés de demapeo per a les dues capes de LDM. L'algoritme proposat aconsegueix un augment de capacitat, en tenir en compte la forma de l'EL en el procés de demapeo de la CL. No obstant açò, el nombre de distàncies Euclidianes a computar pot augmentar significativament, conduint NO sols a receptors fixos més complexos, sinó també a receptors mòbils més complexos. A continuació, es determina la configuració de pilot ATSC 3.0 més adequada per a LDM. Tenint en compte que les dues capes comparteixen el mateix PP, es produeix una contrapartida entre la densitat de pilots (CL) i la redundància sobre les dades (EL). A partir dels resultats de rendiment, es recomana l'ús d'un PP no gaire dens, ja que ja han sigut dissenyats per a fer front a ecos llargs i altes velocitats. L'amplitud pilot òptima depèn de l'estimador de canal en els receptors (ex., es recomana l'amplitud mínima per a una implementació Wiener, mentre que la màxima per a una implementació FFT). També s'investiga la potencial transmissió conjunta de LDM amb tres tecnologies avançades adoptades en ATSC 3.0: les tecnologies d'agregació de MultiRF, els esquemes de MISO distribuït i els de MIMO colocalitzat. S'estudien els potencials casos d'ús, els principals aspectes d'implementació del transmissor i el receptor, i els guanys de rendiment de les configuracions conjuntes per a les dues capes de LDM. Les restriccions addicionals de combinar LDM amb les tecnologies avançades es consideren admissibles, ja que les majors demandes ja estan contemplades en ATSC 3.0 (ex., una segona cadena de recepció). S'obtenen guanys significatius per a la capa mòbil en condicions de recepció per als vianants gràcies a la diversitat en freqüència proporcionada per les tecnologies MultiRF. La conjunció de LDM amb esquemes MISO distribuïts proporciona guanys de rendiment significatius en xarxes SFN per a la capa fixa amb l'esquema d'Alamouti.

During the 2015 Paris Climate Change Conference, world climate scientists and policymakers agreed that global temperatures must not exceed a two degree Celsius increase above pre-industrial levels within the next 30 years. It is estimated that this will require investments of $40 trillion or $1.3 trillion per year in new and mature clean technologies. Currently, only about $0.3 trillion of investment goes to clean technology a year and the majority of that funding goes to mature, proven technologies. There is an investment gap in clean technologies, and the gap is especially pronounced for new and unproven technologies that are necessary to bring down costs of the entire system, and produce quicker breakthroughs in CO₂ mitigation. The gap is partly due to the large losses sustained by venture capitalists-one of the greatest source of early-stage capital-who invested heavily in clean technology companies in the years leading up to the 2008 recession. After the market crashed, federal and state governments ended up being among the few remaining supporters of these technology companies because of their public benefits. However, in order to stay below 2 degree Celsius warming, venture capitalists and other private venture investors must be engaged to invest in the clean technology sector again. Public sector funds are not sufficient. In a sector that has produced few winners while receiving substantial government support, the challenge could not be greater. To address this challenge, we ask three questions of three key actors: How can entrepreneurs attract private investment and scale up pass the Valley of Death? How can venture capitalists build the ability and confidence to invest in the cleantech sector again? How can policymakers address the failure modes that may still exist if investors and entrepreneurs follow best practices? To explore this issue, we conducted interviews, reviewed literature, compiled data from online sources, and compiled information from conferences and workshops. Our findings reveal a "Cleantech Confluence", or a preliminary set of best practices and partnerships. When simultaneously implemented, the Confluence can mobilize multiple sources of private capital into early-stage clean technologies.

Повний текст джерелаComputer science plays an increasingly important role in the analysis and understanding of biological data. In this thesis, we present the multiple characterization problem that addresses, as a combinatorial optimization problem, the detection of plant pathogenic bacterial strains. Indeed, some bacteria are responsible for diseases on a wide range of crops and decrease the market value of the seeds. Diagnostic tests can be designed and require the identification of discriminant observable characters. We have developed several exact methods (branch and bound, linear programming) and approximate (metaheuristics) to minimize the number of characters to deal with. Specifically, considering a subset of individuals representing different groups, the aim for each group is to find a characterization (as a propositional formula) to distinguish the individuals of the group compared to those of the other groups. We use the term “multiple characterization” to highlight the mutual aspect of theses discriminations in the sense “versus a group the other groups” and that for each group. Our work has been validated experimentally on data sets and an in-depth study of the problem’s complexity has been conducted

Повний текст джерелаand communication technologies (ICT), a data warehouse, and Extranet banking.The generic model of ICT can be applied to any particular technology. Results revealed that the pattern of technology diffusion follows the S curve and the dominant variables that may impact on technology diffusion are training, a backlog of problems, and market potential. Furthermore economic returns are obtained only after spending substantially on technological investment. Thus, it is necessary to balance between technological investment and economic returns. The model of diffusion of a data warehouse was developed highlighting the necessity of quality and quantity of knowledge workers. Therefore, training support is an important factor to diffuse this technology. On the other hand, the model of diffusion of Extranet banking revealed that the success of this technology comes from the acceptance by customers. Thus, perceived relative advantages, positive features of the technology and promotional advertising should be taken into consideration. The S curve pattern of technology diffusion is also confirmed by the two technologies.The policy for technology adoption involves the selection of technology, which best fits with identified criteria. The policy analyses of the three technologies confirm that the core important policies that increase technology diffusion and economic gains are increasing positive features of technology, decreasing perceived complexity, increased perceived relative advantages and increasing co-operation between IT people and users. If technology is to support the work performance in an organisation, training support is the dominant policy, whereas if technology facilitates customers directly, marketing strategy such as promotional advertising is vital.The study implied that the banking industry in Thailand is able to use ICT as levers for competitive advantage. ++
However, technological investment in each bank differs depending on size, objectives and readiness in terms of capital and human resources.All the findings have implications for the bank and could be applied to other banks and general policy makers in various business enterprises.

Повний текст джерелаThe globalization of markets and the growing international competitiveness in the last two decades have provided the entry of competing firms in the market, among which are small firms. Notably recognized for their social and economic importance, small enterprises of the industry, trade and services sectors of activity are, in numerical terms, the vast majority of businesses in Brazil. Given the importance of this object of research, this research has as general objective to explore the relationship between the innovation orientation and the internationalization patterns of small and medium enterprises (SMEs). To achieve this general objective, three specific objectives are drawn, which are the study of the internationalization process and patterns of small-and-medium-sized technology based firms and the study of dynamic capabilities for innovation inherent to the distinct internationalization process and patterns of the SMEs. The dynamic capabilities for innovation drive the technological innovation development, namely, innovation in products, processes and services, also fostering the non-technological innovation development, in other words, the Marketing and the organizational. In addition, the dynamic capabilities impact positively on the competitiveness of small businesses in domestic and international markets. The theoretical basis of this research lies in the Internationalization Theories, from the Behavioral School and the Economic School, for Business Internationalization, and the Innovation Theories, referring to the Dynamic Capabilities for Innovation. In order to better understand the object of research, for each topic there is a section concerning to the SMEs. The sectoral diversity of the participants firms contributed to the magnitude of results on the dynamic capabilities for innovation of Brazilian SMEs, as well as to identify their internationalization patterns. From a qualitative study, the analysis show that Brazilian SMEs seek to differentiate through innovation in their international operating markets. Regarding the internationalization patterns of Brazilian SMEs, they differ in some criteria than shown in the literature. Therefore, the analysis of dynamic capabilities for innovation shows that small Brazilian companies have high potential for the innovation development, even with the existence of external barriers. Concerning the internationalization, the SMEs of the study have specific international patterns, requiring, therefore, criteria approaches in relation to literature. As academic contributions, the research presents the analysis of dynamic capabilities for innovation related to the pattern of internationalization of Brazilian SMEs, presenting emerging variables from the research themes. Finally, as managerial contributions, the analysis of the cases enables verifying how firms seek to position themselves competitively in international markets

Повний текст джерелаEsta pesquisa teve por objetivo analisar as contribuiÃÃes de metodologia desenvolvida, com suporte de tecnologias digitais, para o desenvolvimento do conceito de covariaÃÃo presente nas estruturas multiplicativas. Para isso, foram realizadas anÃlises das situaÃÃes presentes no campo conceitual multiplicativo, verificando a ocorrÃncia, ou nÃo, da covariaÃÃo. O desenvolvimento das atividades foi fundamentado em estudos relacionados Ãs contribuiÃÃes das mÃltiplas representaÃÃes para a aprendizagem e da abordagem seres-humanos-com-mÃdias. Utilizou-se, como metodologia, a pesquisa de intervenÃÃo. A investigaÃÃo foi realizada em uma Escola Municipal de Tempo Integral, localizada no municÃpio de Fortaleza - CearÃ, com estudantes de uma das turmas do 6 ano do Ensino Fundamental. A turma de alunos foi dividida em: Grupo Controle (GC), com 15 alunos e Grupo Experimental (GE), com 12 alunos. A investigaÃÃo foi dividida em trÃs etapas: prÃ-teste, intervenÃÃo e pÃs-teste. Todos os alunos, dos dois grupos, participaram do prÃ-teste e do pÃs-teste, aplicados individualmente e sem uso do computador. Tendo sido aplicados para diagnosticar os conhecimentos dos alunos em relaÃÃo à compreensÃo de situaÃÃes de proporÃÃo simples, de proporÃÃo mÃltipla, de proporÃÃo dupla, de interpretaÃÃo e construÃÃo de grÃficos lineares e compreensÃo de padrÃo de tabelas. A intervenÃÃo aconteceu apenas com o GE, no momento das aulas de MatemÃtica. Essa etapa teve duraÃÃo de 3 meses, com 18 encontros. As atividades desenvolvidas para esses encontros, utilizavam tecnologias digitais como: software Geogebra, recurso digital Equilibrando proporÃÃes, aplicativo online Cacoo, WhatsApp e blog. O GC manteve as aulas de MatemÃtica e de disciplinas eletivas, nos mesmos horÃrios do GE. Os dados foram analisados de modo a conhecer e compreender o desempenho dos alunos antes e apÃs as atividades; os teoremas-em-aÃÃo mobilizados durante a intervenÃÃo e suas evoluÃÃes; e as contribuiÃÃes das tecnologias usadas para a compreensÃo do conceito de covariaÃÃo. Os estudantes submetidos à intervenÃÃo apresentaram, estatisticamente, um desempenho superior, quando comparados aos estudantes do GC, demonstrando a eficÃcia da metodologia. Constatou-se, ainda, a modificaÃÃo de esquemas por meio de estratÃgias mais elaboradas, mesmo para situaÃÃes que jà eram conhecidas pelos estudantes do GE. As tecnologias digitais utilizadas contribuÃram para a compreensÃo da invariÃncia e da covariaÃÃo, ao relacionar mÃltiplas representaÃÃes de forma dinÃmica, possibilitar a produÃÃo de conhecimento e a significaÃÃo de contextos sociais e matemÃticos.

Повний текст джерелаOur research object is twofold: understand a strategic organizational competences bulding using IT, on the one hand, and go beyond the existing analysis of impacts of the IT models, integrating a multidimensional approach, on the other hand. We privileged an empirical approach beginning with a pilot case study that allowed us to define a theoretical framework of an abductive way, by a constant back and forth between the field and the theoretical existing constructs. The conceptual framework is a synthesis of the various RBV strands integrating the concept of organizational learning. The results of a multicase study underline the diffused and partially intentional character of a process, requiring interaction of additional resources highly dependent from the past, and leading to improve efficiency of the routines and dynamic adaptability. We propose a design of the process and discuss significant concepts for the study of this phenomenon

Повний текст джерелаI tunga lastbilsbranschen spelar sälj- och servicenätverk en viktig roll. Investeringar i nätverken är dyra, och för att vara lönsamma krävs en viss servicevolym. Det är särskilt utmanande på nya marknader, där efterfrågan är låg och obestämd. En möjlig lösning är att dela sälj- och servicenätverk med konkurrenter. Simultant samarbete och konkurrens, så kallad co-opetition, är ett komplext och motsägande fenomen, som tidigare forskats på med fokus på samarbete inom utveckling. Denna uppsats undersöker co-opetition inom sälj, genom att titta på hur tunga lastbilsföretag kan ingå partnerskap inom sälj- och servicenätverk tillsammans med konkurrenter. Detta görs genom en litteraturgenomgång samt en flerfallstudie. Utifrån vår analys presenteras ett ramverk för att bedöma och utforma potentiella partnerskap med konkurrenter. Ramverket består av sju viktiga faktorer för framgångsrika partnerskap inom sälj- och servicenätverk tillsammans med konkurrenter; kulturell passform (cultural fit), icke-konkurrerande produkter, kompatibla mål, överbliven kapacitet i nätverket, dedikerade säljare, högt engagemang och tålmodig implementering. Uppsatsen bidrar till forskning inom co-opetition inom sälj och med diskussion kring begreppen konkurrens, framgång och partnerskap.

Повний текст джерелаIn electron beam lithography, a new proximity affects correction strategy has been imagined to push the resolution capabilities beyond the limitations of the standard dose modulation. In this work, the proximity affects inherent to e-beam lithography have been studied on the newest e-beam tools available at LETI. First, the limits of the standard dose modulation correction have been evaluated. The influences of each step of the lithographic process have also been analyzed from a theoretical point a view. A simulation approach was built and used to determine the impact of each of these steps on the patterned features. Then, a new writing strategy has been fully developed. It involves sub resolution features known as eRIF (electron Resolution Improvement features) which provide a finer control of the dose profile into the resist. Since the eRIF are exposed a top the nominal features, this new writing strategy is called multiple pass exposure. In this work, the position, the dose and the design of the eRIF have been studied and optimized to get the best of this new strategy. To do so, experiments were led in a clean room environment, and minimization algorithms have been developed. It has been demonstrated that the eRIF provide a significant gain compared to the standard dose modulation. Improvements have been observed even on the most critical levels of the Integrated circuits. By using the multiple pass exposure with optimized eRIF, the resolution capabilities of the e-beam tool have been reduced by 2 technological nodes. The design rules that have been determined to use the eRIF the most efficient way were finally implemented in INSCALE, the new data preparation software developed by ASELTA NANOGRAPHICS. This way, multiple pass exposure can be used in an automated mode to correct full layouts

Повний текст джерелаEm todos os domínios da sociedade atual, da Educação em geral e da Educação Especial em particular, as tecnologias da informação são aplicadas no sentido de melhorar a qualidade de vida e, neste contexto, de melhorar os processos de ensino e aprendizagem das crianças multideficientes, na medida que, as características destes alunos colocam grandes desafios às escolas e aos profissionais que com eles trabalham. O presente estudo incide sobre a perceção dos professores de Educação Especial, na Região Autónoma dos Açores (RAA), face à adoção das Tecnologias da Informação e Comunicação (TIC) na prática pedagógica com alunos com multideficiência. Procura também compreender quais são as atitudes dos professores de Educação Especial face às TIC e o seu parecer na adoção das mesmas no processo educativo destes alunos. No decorrer da planificação da presente investigação, optou-se por um estudo descritivo de cariz quantitativo. A recolha de dados foi feita através de um inquérito por questionário ao qual responderam 97 professores. Conclui-se que a idade dos docentes não tem qualquer influência na utilização das TIC; os docentes com menos experiência profissional apresentam uma maior apetência pelo conhecimento e uso das TIC; os docentes com mestrado ou doutoramento usam mais aplicativos de exploração lúdica para alunos com multideficiência do que os docentes especializados; quanto mais elevada é a utilização das TIC e a formação contínua na área, maior é a perceção de benefícios para as crianças multideficientes e mais elevada é a frequência da sua utilização; os docentes da amostra, ainda referem sentir muitas necessidades formativas referentes ao uso das TIC na multideficiência.
In all areas of modern society, Education in general and Special Education, in particular, information technology is applied to improve the quality of life and, in this context, to improve the teaching and learning processes of children with multiple disabilities, in so far that, the characteristics of these students pose major challenges to schools and professionals who work with them. This study focuses on the perception of Special Education teachers in the Região Autónoma dos Açores (RAA), due to the adoption of Information and Communication Technologies (ICT) in multiple disabilities teaching practice. Also seeks to understand the attitudes of Special Education teachers towards ICT and its opinion on the adoption of the same in the educational process of these students. During the planning phase of this research was opted for apply a descriptive study of quantitative nature. Data gathering was carried through questionnaire survey to which 97 teachers responded. We conclude that the age of teachers has no influence on the use of ICT; teachers with less teaching experience have a greater keenness for knowledge and use of ICT; teachers with master's or doctorate use more playful exploration applications for students with multiple disabilities than specialized teachers; the higher the use of ICT and continuing education in the area, the higher is the perception of benefits for children with multiple disabilities; overall, the higher is the frequency of use; the teachers in sample also showed many training needs regarding the use of ICT in multiple disabilities.

Повний текст джерелаOver the last ten years, multi-antenna systems (MIMO) for mobile and fixed wireless communications have revolutionized the possibilities offered for numerous telecommunication application domains. Using multiple antennas at both ends of the link considerably increases the capacity of wireless systems. However, the digital algorithms needed to realize these systems are complex and constitute a challenge in order to define powerful hardware architectures. The goal of the present work centers specifically on the optimal definition of architectural solutions to combat this problem in a CDMA context. The first aspect of this work is a deepened study of space-time algorithms and design methods with regards to an efficient hardware implementation. Numerous detection schemes are proposed in the litterature and are applicable following three criteria : quality of service, binary throughput and algorithmic complexity. The latter constitutes a strong limitation for a low cost implementation of mobiles including these applications. Thus, it is necessary to use powerful tools to simulate, evaluate and rapidly prototype these new systems which constitute likely candidates for fourth generation telecommunication systems. The second aspect is the realization of an uncoded multi-antenna transceiver, integrating CDMA in a wideband channel case. A WCDMA mono-antenna system, generalized to any antenna array, has been integrated and simulated on the Lyrtech rapid prototyping platform. The developped architecture integrates the main baseband processing modules, such as Nyquist filtering, multiple path detection and detection itself. The MIMO-WCDMA prototype is characterized by its flexibility with regards to the number of inputs, format of samples, characteristics of the wireless channel and the targeted technology (ASIC, FPGA). The third aspect is more prospective since it introduces new methods to reduce the hardware cost of multi-antenna systems. The principle of dynamic allocation of the fixed point format is presented with the goal of adapting the data encoding according to the wireless channel's characteristics and consequently minimizing the circuit's complexity. Also, the concept of adaptive architectures is proposed to reduce the power consumption in an embedded system according to application context
