The research has a descriptive-analytical, qualitative approach and investigates the MBL and MN postings on Facebook between April 11 and 17, 2016. The study follows the methodological framework of Depth Hermeneutics proposed by Thompson (2011), whose includes the stages: (1) Interpretation of Doxa; (2) Socio-historical analysis; (3) Formal Analysis; and (4) Interpretation/Re-interpretation. The first stage includes the theoretical chapters that discuss the paradigm shift in communication and social relations based on the evolution of technologies, focusing on the transformations of the Digital Age. In the second phase, we seek to reconstitute the historical-social context of Brazil between the years of 2013 and 2016 with the focus on the street protests and the political polarization. For the formal analysis of the messages, we used the Content Analysis tool (BARDIN, 1977) with the help of Iramuteq software for the lexical analysis and similarity of the textual corpus. The analytical categories were constructed and adapted from the meaning carriers (JASPER, 2016), the floating reading of the messages and the modes of operation of the ideology (THOMPSON, 2011). In the sequence, we perform the reinterpretation, combining the theoretical framework, the historical-social context, the investigation of the origin and the political tendency of MBL and MN and the analytical categories. In the result, we have identified that both virtual communities have developed similar communication strategies to construct their narratives about impeachment. However, the discourses were dissonant regarding the political position and the role attributed to the state and the market. Tensions between the political, economic, business, media, communication and legal social fields were preponderant for a negative social representation of the Dilma government, of the Partido dos Trabalhadores and for the polarization of opinions. At the end we propose reflections on cyberdemocracy, launching arguments that highlight advances, achievements and challenges that must be faced to build the future with freedom, equality and fraternity. / Essa dissertação estuda as estratégias de comunicação das comunidades virtuais do Movimento Brasil Livre (MBL) e da Mídia NINJA (MN) para mobilizar os cidadãos a participar do processo de impeachment da presidente Dilma Rousseff em 2016. A pesquisa tem caráter descritivo-analítico, abordagem qualitativa e investiga as postagens do MBL e da MN no Facebook entre os dias 11 e 17 de abril de 2016. O estudo segue o referencial metodológico da Hermenêutica de Profundidade (HP) proposto por Thompson (2011), cujo percurso inclui as fases: (1) Interpretação da Doxa; (2) Análise sócio-histórica; (3) Análise Formal; e (4) Interpretação/Re-interpretação. A primeira fase abrange os capítulos teóricos que discutem a mudança de paradigma na comunicação e nas relações sociais com base na evolução das tecnologias, centrando-se nas transformações da Era Digital. Na segunda fase, buscamos reconstituir o contexto histórico-social do Brasil entre os anos de 2013 e 2016 com o olhar nas manifestações de rua e na polarização política. Para a análise formal das mensagens, utilizamos a ferramenta da Análise de Conteúdo (BARDIN, 1977) com o auxílio do software Iramuteq para as análises lexical e de similitude do corpus textual. As categorias analíticas foram construídas e adaptadas a partir dos portadores de significado (JASPER, 2016), da leitura flutuante das mensagens e dos modos de operação da ideologia (THOMPSON, 2011). Na sequência, realizamos a reinterpretação, combinando o arcabouço teórico, o contexto históricosocial, a investigação da origem e tendência política do MBL e da MN e as categorias analíticas. Como resultado, identificamos que ambas as comunidades virtuais desenvolveram estratégias de comunicação semelhantes para construir suas narrativas sobre o impeachment. No entanto, os discursos foram dissonantes quanto ao posicionamento político e o papel atribuído ao Estado e ao mercado. Tensões entre os campos sociais político, econômico, empresarial, midiático, comunicacional e jurídico foram preponderantes para uma representação social negativa do governo Dilma, do Partido dos Trabalhadores e para a polarização de opiniões. Ao final propomos reflexões sobre a ciberdemocracia, lançando argumentos que destacam avanços, conquistas e desafios que precisam ser enfrentados para construirmos o futuro com liberdade, igualdade e fraternidade.

The area of this work is a combination of draping and printing. It strives towards the technique that dazzles the eye with illusions of more than one dimension. As a viewer you will believe that the prints are real drapings while they are flat surfaces. Today prints in fashion are categorized as placed prints or all-over prints, and generally created as a flat surface to decorate the garments. In this work the idea is to manipulate and challenge the boundaries of print and give it life through the body shapes and in the movement. Potentially this work could be an introduction to a new way of working with prints in fashion. This work could poosibly be presented as a new technique where placed- print and all-over prints comes together- called placed all-over prints. Also, it could develop into further techniques in using two-dimensional flatness and save fabric in using photography as an option to the real three-dimensional drapings. Furthermore could it mean savings in material as a conscious choice in the process ? This investigation explores two particular kinds of techniques, - print and draping, that are merged into one expression. The aims of this work is to find new ways of using print in combination with draping in dress and explore the possibilities to find a new technique to create interesting womenswear. To unite dimensions like two-dimensional and three-dimensional as a method of finding new forms and expressions. Through experiments with striped textiles the focus is to investigate the possibilities of greater visual effects on two-dimensional prints. For a depth and to exaggerate the directions in the fabric before translating it into a flat surface the striped textile can be a tool for further design. The striped textile has the potential to help the eye to understand the directions in the print and can be used in more than one dimension and color. To explore how to create 3D effect on 2D in print design through draping in dress is the aim of this work. / Program: Modedesignutbildningen

O desempenho desta abordagem será medido através de uma simulação de monte Carlo / This project aims to design a digital data communication link for unmaned aerial vehicles. We will focus the main challenges and their impacts in the communication system. The project was divided in an analog and digital block. The analog block address the power requirements that make the system works by using a link budget procedure. The digital block will use the OFDM transmission technique. In this work we also suggest a channel estimation procedure via pilot tones. The performance of this approach will be measured by Monte Carlo Simulation

As redes sociais virtuais são um meio de comunicação que se diferencia da mídia tradicional por uma razão fundamental: a distribuição entre os usuários da capacidade de comunicar. O usuário dessas redes não se limita à posição de espectador, pois ele pode ser também autor, produtor e promotor de textos ou outros materiais. Cai, portanto, o modelo top-down unidirecional, e ganha espaço uma comunicação bidirecional (entre usuários) e difusa, o que representa a transição de uma topologia de árvore para outra, oposta, de rizoma. O objetivo deste trabalho é compreender a comunicação nas redes sociais virtuais, o que será feito analisando-as externa e internamente. Visa-se a formar, dessa maneira, um construto sobre essas redes quanto à sua técnica e seus usuários, sua forma e suas identidades, o que delas irradia e nelas se desenvolve, e, assim, precisar as características fundamentais da comunicação nesses espaços. / Virtual social networks are a means of communication that differs from traditional media due to one fundamental reason: the power to communicate is distributed among their users. In these networks, the user is not merely the spectator, but also the author, the producer, and the promoter of texts or other materials. Therefore, these networks put aside the unidirectional top-down model, giving ground to the emergence of a bidirectional and diffuse communication, which represents a topological transition from tree to rhizome. This research looks for understanding the communication in virtual social networks by analyzing them internally and externally. It seeks building a construct on these networks\' technique and users, their shape and identities, what irradiates from them and what grows in them, thus allowing the understanding of the fundamental communication characteristics in these spaces.

O projeto consiste em uma pesquisa sobre a comunicação digital, especialmente sobre os blogs , como ferramenta de relacionamento direta entre a organização e seus públicos. Neste contexto, as relações públicas (dentro do contexto da comunicação organizacional) são fundamentais para identificar que públicos têm condições de se relacionar por meio da Web e qual é o melhor conteúdo, layout, ferramenta e funcionalidades que o meio digital deve apresentar para atingir com efetividade o target visado. Além disso, acredita-se que a comunicação simétrica de mão dupla ganha força com a comunicação digital, o que contribui para o fortalecimento dos relacionamentos criados pela comunicação organizacional e pelas relações públicas digitais. / This project consists of research about digital communication, especially weblogs, as a relationship tool between the companies and their publics. In this context, the public relations are fundamental to identify which publics have conditions to interact via web and what are the best content, layout, tool and functionality that digital vehicles should present to target the audiences effectively. Besides that, the simetric and bidirectional communication gets stronger with digital communications, which contributes to a better relationship created by digital public relations.

O presente trabalho é uma pesquisa tecnológica (P&D) de inovação tecnológica de produto para o mercado brasileiro, que visa desenvolver um transmissor de pressão inteligente de alta exatidão com protocolo HART e sensor piezoresistivo em parceria LSI-USP / MEMS Ltda. Fornecendo assim um protótipo de um produto competitivo no mercado brasileiro. Neste trabalho se apresenta uma arquitetura baseada nos transmissores 4-20 mA de alta exatidão da MEMS Ltda. Essa arquitetura mantém as características de desemprenho da medição analógica e adiciona os componentes necessários para suportar as funções do padrão HART com camada física Bell 202. Além da arquitetura, neste documento é apresentado: o desenvolvimento das interfaces entre o algoritmo de compensação e os algoritmos responsáveis da comunicação digital, as modificações no circuito de controle da corrente de laço para permitir a modulação do sinal de 1200 Hz e 2200 Hz usado pela comunicação digital, e o projeto de alimentação do transmissor, que foi projetado visando a eficiência para respeitar os limites de consumo de corrente. Os resultados obtidos com essa nova arquitetura, apresentam que são mantidas as características dos transmissores 4-20 mA usados como base, e que a medição digital tem um nível de erro 0,05 %FS (porcentagem de fundo de escala) menor do que a saída analógica do mesmo transmissor, valor considerável comparado com o 0,2 %FS que é o nível de erro total do sistema. Os protótipos usados para as medições foram caracterizados num processo que levou 35 dias de operação continua, validando assim o projeto elétrico e software desenvolvido. / This thesis consists of a technical research (P&D) on technological innovations of a highly accurate intelligent pressure transmitter using a HART protocol and piezoresistive sensors in collaboration with LSI-USP / MEMS Ltda. The outcome consists of a prototype of a competitive product in the Brazilian market. This project presents a product architecture based on highly accurate 4-20mA MEMS Ltda. transmitters. It maintains the features necessary for analogical measurements and adds components, which are compatible with the functions of HART with a Bell 202 physical layer. In addition to the architecture, this document presents the development of: interfaces between the compensation algorithm and digital communication algorithms, modifications of the current loop control circuit to allow signal modulation used by digital communications of 1200Hz and 2000Hz, a voltage source project, which envisioned efficiency and considered the limits of current consumption. Results of this architecture show that the 4-20mA transmitter´s characteristics, used as a starting point for the product, are maintained and that digital measurements present 0.05%FS (Full Scale) less error than analogical measurements taken by the same transmitter. This presents a significant error reduction when compared to the total error of the system, which is 0, 2 %FS. The prototypes used for measurements were tested during 35 continuous days, validating their electrical installation and software.

Esta Tese apresenta uma contribuição para avaliação da comunicação digital na operação de veículos aéreos não tripulados (VANT) no ambiente aeronáutico. A comunicação digital aeronáutica relaciona-se diretamente ao nível de segurança crítica desejado para o controle do fluxo de tráfego aéreo, por parte de autoridades e de órgãos normativos, os quais possuem como objetivo tornar a comunicação uniforme para todos os continentes. Diversas são as discussões acerca do nível de segurança crítica que a comunicação digital entre VANT e controle em terra possa exibir, sempre buscando redução da exposição a riscos inerentes à operação desse tipo de veículo. Nesse contexto, a proposta desta Tese é avaliar a segurança na comunicação digital, por meio do uso de injeção de falhas, para operações de veículos aéreos não tripulados. Este trabalho descreve a importância de analisar as interferências causadas por falhas na comunicação digital, relacionadas ao envio de mensagens entre o órgão de controle e a aeronave não tripulada. Também são definidos quais os tipos de falhas que causam um maior impacto na comunicação, bem como quais os parâmetros que devem ser utilizados para manipulação das variáveis de falhas na comunicação. Para atender a avaliação proposta, foi utilizado o ambiente simulado que reúne as características do ambiente aeronáutico, denominado PipE-SEC (Plataforma Integrada para Ensaios de Sistemas Embarcados Críticos), bem como o protocolo CPDLC (Controller-Pilot Data Link Communications) para troca de mensagens digitais. / This thesis presents a contribution to the evaluation of digital communication in the operation of unmanned aerial vehicles (UAV) in the aeronautical environment. Aeronautical digital communication relates directly to the critical safety level required for controlling the air traffic flow by authorities and regulatory agencies, which are aimed at making communication uniform for all continents. There are several discussions about the safety critical level that digital communication between UAVs and ground control can display, always seeking to reduce exposure to risks inherent in the operation of such vehicles. In this context, the proposal of this thesis is to evaluate the safety in digital communication, through the use of fault injection for operations of UAV. This work describes the importance of analyzing the interference caused by faults in digital communication related to sending messages between the control agency and the UAV. There are also defined what types of faults cause a greater impact on communication as well as which parameters should be used to simulate communication faults. To answer the proposed evaluation, we used the simulated environment that combines the features of the aeronautical environment, called PIpE-SEC (Integrated Platform for Test Critical Embedded Systems), as well as the protocol CPDLC (Controller-Pilot Data Link Communications) to exchange digital messages.

This qualitative study aims to examine how Tillväxt Motala AB are working strategically to market Motala, a middle-sized city in Sweden. The study is implemented through qualitative semi-structured interviews with employees at Tillväxt Motala AB. The theories on which this study is built are strategic communication, place branding and marketing communication, and a few concepts regarding propaganda. The results show an integration of marketing and communication work roles at the organisation of interest. A deficiency concerning internal communication at Tillväxt Motala AB, due to lack of time, was found. Furthermore, Tillväxt Motala AB has a unique contact with both local and external networks from which employees benefit in their work regarding the place branding. Consensus in the interpretation of place branding as a definition was found among the employees - to highlight a place's positive qualities through communication to meet the needs of the business sector, visitors and residents and to differentiate themselves.

The boom in data communications that started in the 1960s is a long way from abating. The early and mid 1980s will see a new generation of digital data transmission services come into operation that could change the ways business is conducted. "Information management and exploitation will change the fabric of society", according to Nicolas Mokhoff, Associate Editor of IEEE Spectrum Magazine. Manipulated by microelectronic, computer, radio and other electronic disciplines, information has become a vital commodity at the trade exchange. But unlike the prices of most commodities today, the price for exchange of information is decreasing because of electronics. One of the principal contributors to this decrease has been the geosynchronous telecommunications satellite, due to rapid advances in space and communications technology and the resulting cost-effectiveness achieved in applying that technology. Advances in IC technology have made digital telephony an equal partner with analogue. The inherent advantages of digital reliability, low cost and smaller packaging are prompting Telecom to phase out present equipment and expand new services with a digital hierarchy, such as the Digital Data Service being introduced in late 1982. Services employing advanced satellite and microwave technology, and also the existing and upgraded telephone systems, will have at least two things in common: they will transmit and switch data digitally, including coded speech, and the data will be transmitted in bursts. The technology that may expand fastest is the second generation of commercial communications satellites. Pier Bargellini, a senior scientist at Comsat Laboratories, says that "without the use of satellites as reflectors for source and data channels, television signals could not be shared by remote areas, long-distance telephone services would be constricted and the data exchange for the business world would be hampered." Changes in the communications industry have been so dramatic (particularly with regard to satellites) that government bodies (including the Australian Federal Government) have been forced to reexamine long-standing communications practices. In October 1979 the Minister for Post and Telecommunications announced the Governments decision that it would be in the national interest to establish a communications satellite system for Australia. At that time, the Minister also announced that, a Satellite Project Office would be established within the Postal and Telecommunications Department to set in train the planning activities necessary for the introduction of the system. The SPO has been operational within the Department since late 1979, and 2. consultation of system service requirements in particular has involved liaison with a broad spectrum of interests including Commonwealth departments. Figure 1 of Appendix A testifies to the Australian Government's policy of supplying outback communities with improved communications services (including television) by using satellite facilities. Very little is known about the benefits and needs (in Australia) that a data communications satellite system might be able to fulfil, including those needs of the Department of Social Security. This is mainly due to the lack of specific details about the final configurations and costs of the separate satellite services, which wont be known until late 1981. This paper is , therefore, an initial but detailed examination of the hardware and software subsystems which constitute a domestic telecommunications satellite system. More specifically, the paper considers the on-board equipment of a communications satellite (the space segment - including satellite launch and orbit characteristics, and signal propagation delay and attenuation), and the earth stations (the ground segment - including signal modulation, multiple access and computer application considerations); all as dictated by Australian geographical, economic and communications traffic density characteristics. The paper then considers some of the possible methods Australian corporations and government departments may adopt to utilise satellite communications links, particularly for data communications. A second paper will re-examine the situation by applying the specific facilities and costs, when they are known (these will be announced by the Satellite Project Office after contracts for the space and ground segments have been let), to a large, low-traffic, interactive multipoint network such as that of the Department of Social Security.
