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.

Esta pesquisa se insere nas linhas de investigação do Centro de Pesquisa ATOPOS, da Escola de Comunicação e Artes da Universidade de São Paulo (ECA/USP) sobre os aspectos teóricos das mídias digitais. Propõe compreender, estudar, analisar e verificar como a sociabilidade expressa nos blogs está contribuindo para ressignificação e identificação dos valores culturais entre os dekasseguis por meio da construção de uma identidade comunicativa na web. A metodologia baseia-se em uma análise de fundo qualitativo da composição da postagem de oito blogs em três períodos determinados, levando em conta critérios trazidos pela determinação da tipologia de blogs e existência de comunidades e espaços conversacionais na rede digital e por fragmentos de análise usados pela análise do discurso. Entre os resultados podemos afirmar que o termo comunidade dekassegui não é apropriado se for levado em conta a sociologia clássica, porém este termo pode ser aplicado no âmbito digital. Também o termo mediascape, de Arjun Appadurai (1996), e situação social tecnológica (MEYROWITZ, 1985) se mostram presentes e relidos ao serem aplicados a este grupo. / This research fits into the lines of investigation of the ATOPOS Research Center, of Escola de Comunicação e Artes da Universidade de São Paulo [School of Communication and Arts of the University of São Paulo] (ECA/USP) on the theoretical aspects of digital media. It is intended to understanding, studying, analyzing and verifying how the sociability expressed in the blogs contributes to the redefinition and identification of the cultural values among the dekasseguis through the construction of a communicative identity in the Web. The methodology is based on the qualitative analysis of the composition of posts of eight blogs, in three determined periods, considering criteria brought by speech analysis and determination of the typology of blogs and the existence of communities and conversational spaces in the digital web. Among the results, one can state that the term dekassegui community is not appropriate, considering the classic sociology, but such term can be applied in the digital sphere. Also, the terms mediascape, of Arjun Appadurai (1996), and social technologic situation (Meyrowitz, 1985) are present and redefined when applied to this group.

Filtering is an important part of digital processing, since the applications often require a change of features of a digital or analog signal. A digital filter is a device or a system that removes or alters certain parts of a signal. Optical fibers are used to transmit information over longer distances and at higher bandwidths than traditional copper cables. In order to enable high-rate transmission in optical communication systems, it is necessary to have a filter that compensates for chromatic dispersion in optic links, since the dispersion alters the signal in an unwanted way. This thesis presents the implementation and evaluation of two filter architectures, used in fiber-optic communication. The clock frequency of the implemented designs reaches 475 MHz, which results in a processing speed of 60 GS/s.

Este projeto tem como objetivo a especicação de um enlace de comunicação digital para veículos aéreos não tripulados. Os principais desaos presentes no meio de transmissão serão evidenciados, assim como o impacto acarretado no sistema de comunicação. O projeto foi dividido entre a parte analógica e digital. A parte analógica tratará dos requisitos de potência para o devido funcionamento do canal através do procedimento de link budget. O projeto da parte digital, por sua vez, empregará a técnica de transmissão OFDM. No presente trabalho foi sugerido um método de estimação do canal utilizando os tons pilotos. 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
