Flexible Intercom System Design for Telemetry Sites and Other Test Environments

Bougan, Timothy B. 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / Testing avionics and military equipment often requires extensive facilities and numerous operators working in concert. In many cases these facilities are mobile and can be set up at remote locations. In almost all situations the equipment is loud and makes communication between the operators difficult if not impossible. Furthermore, many sites must transmit, receive, relay, and record telemetry signals. To facilitate communication, most telemetry and test sites incorporate some form of intercom system. While intercom systems themselves are a not a new concept and are available in many forms, finding one that meets the requirements of the test community (at a reasonable cost) can be a significant challenge. Specifically, the test director must often communicate with several manned stations, aircraft, remote sites, and/or simultaneously record all or some of the audio traffic. Furthermore, it is often necessary to conference all or some of the channels (so that all those involved can fully follow the progress of the test). The needs can be so specialized that they often demand a very expensive "custom" solution. This paper describes the philosophy and design of a multi-channel intercom system specifically intended to support the needs of the telemetry and test community. It discusses in detail how to use state-of-the-art field programmable gate arrays, relatively inexpensive computers and digital signal processors, and some other new technologies to design a fully digital, completely non-blocking intercom system. The system described is radically different from conventional designs but is much more cost effective (thanks to recent developments in programmable logic, microprocessor performance, and serial/digital technologies). This paper presents, as an example, the conception and design of an actual system purchased by the US government.

No. of bitstreams: 1 moraes_ecg_dr_bauru.pdf: 4040331 bytes, checksum: 2a19a4abe9d8d36393ef3dff26e544ff (MD5) Previous issue date: 2018-08-27 / Em uma sociedade permeada pela incorporação das tecnologias digitais nas diversas ações do cotidiano, a mediatização ganha relevância em outras instâncias, como a dos eventos científicos. Essas ações, pautadas por atividades presenciais, reúnem o público para tratar de temas relacionados às ciências nas distintas áreas do conhecimento. Considerando a mediatização como o conceito que trata das transformações sociais e culturais, resultantes da ubiquidade dos meios de comunicação na sociedade, nos eventos científicos, a inserção das tecnologias digitais tem contribuído para novos formatos dessas ações, bem como novas modalidades de interação. Diante do exposto, este trabalho visa analisar como o processo de mediatização modifica os eventos científicos. Para isso, inicialmente, construímos um referencial teórico pautado no tema dos eventos e mediatização e seus desdobramentos. Para a realização da pesquisa, empregamos o método de estudo de caso, tendo como objeto de pesquisa o XXXIX Congresso Brasileiro de Estudos Interdisciplinares da Comunicação, promovido pela Intercom. De acordo com esse método, realizamos três pesquisas: observação participante no congresso presencial; análise da página do Facebook, criada para o evento e entrevistas com os diretores da Intercom, para, posteriormente fazer a triangulação dos resultados. Os resultados indicam a relevância das atividades presenciais, sob a perspectiva dos debates entre pares, importantes para o aprimoramento dos trabalhos, como as vivências dos participantes, que resultam da sinergia proporcionada pelo clima do evento. Por outro lado, as tecnologias digitais foram incorporadas ao evento de modo que se tornaram essenciais à sua realização. Elas, inicialmente, facilitam e agilizaram os procedimentos para a organização e participação no congresso, além de proporcionar o acesso livre ao conteúdo científico publicado nos anais eletrônicos do evento. Além disso, a análise demonstrou que as redes sociais digitais são utilizadas para a interação entre os participantes, de modo colaborativo, evidenciando o caráter ativo desse público. Essas redes constituem, ainda, importante fonte de dados que podem contribuir para que os organizadores identifiquem os interesses e expectativas dos participantes. De acordo com os resultados, as tecnologias digitais permeiam todas as etapas dos eventos científicos, mas não substituem as propriedades exclusivas da experiência presencial, constituindo, portanto, uma forma de mediatização indireta. / In a society surrounded by the incorporation of the digital technologies in several daily activities, the mediatization gets its relevancy in other events, like the scientific ones, these events, tied by presential activities, gather the public to deal with themes related to science in different areas of knowledge. Considering the mediatization as a concept that treats the social and cultural transformations as a result of the ubiquity of the communication means in the society, at the scientific events, the insertion of digital technologies has contributed for the format of these new actions, as well as new interaction modalities. Given the above, this paper aims at analyzing how the mediatization process modifies the scientific events. For this, initially, we have built a theoretical referential based on the theme of events, mediatization and its consequences. For the research, we have used a case study method, having as the research object the XXXIX Interdisciplinary Communication Study Brazilian Congress, promoted by Intercom. According to this method, we have performed three researches: observation of the participants at the presential congress; analysis of the Facebook page created for the event and interview with Intercom directors, so that later on the triangulation of results could be made. The results indicate the relevance of the presential activities under the perspective of peer discussions, which are important for the enhancement of the work as well as the experience of the participants, which result in the synergy provided by the events atmosphere. On the other hand, the digital technologies have been incorporated to the event in a way that they became essential to its execution. They have initially made the congress organization and participation easier and faster, besides providing free access to the scientific content published at the events digital records. Besides that, the analysis has demonstrated that the digital social media are used for the interaction of the participants, in a collaborative way, evidencing the active behavior of this public. These networks also represent an important source of data that can contribute for the organizers to identify interests and expectations of the participants. According to the results, the digital technologies are present in all phases of the scientific events, but they do not replace the exclusive properties of the presential experience, composing then a way of indirect mediatization.

Ανάπτυξη και διαχείριση διαδικτυακού εκπαιδευτικού λογισμικού / Development and maintenance of a web based educational software

Φωκά, Γεωργία 24 January 2011 (has links)
Στην εργασία αυτή, παρουσιάζεται η ανερχόμενη μέθοδος εκμάθησης Intercomprehension καθώς και η αξιοποίηση αυτής από το διαδικτυακό εκπαιδευτικό λογισμικό εκμάθησης ξένων γλωσσών ‘Intercom’. Η συγκεκριμένη εφαρμογή στηρίζεται αποκλειστικά στη μεθοδολογία αυτή, η οποία και αναπτύσσει μια μέθοδο διδασκαλίας για την προώθηση της αμοιβαίας κατανόησης, στηριζόμενη σε κοινές στρατηγικές που αξιοποιούν τις μη-γλωσσικές πτυχές της δεκτικής ικανότητας. Το λογισμικό αυτό, αποτελείται από ένα σύνολο διαδικτυακών δραστηριοτήτων αλληλεπίδρασης με σκοπό την εκμάθηση τεσσάρων γλωσσών: Γερμανικά, Πορτογαλικά, Βουλγάρικα και Ελληνικά, αξιοποιώντας παράλληλα δύο γλώσσες οδηγούς (Αγγλικά και Γαλλικά). Η πρωτοτυπία του εκπαιδευτικού αυτού λογισμικού, συνιστάται στην εξέλιξη της συγκεκριμένης μεθόδου διδασκαλίας επεκτείνοντας την και πέρα των γλωσσικών οικογενειών παράλληλα με την αξιοποίηση μη γλωσσικών πτυχών κατά την εκμάθηση μιας ξένης γλώσσας. / The purpose of this paper is to present the new learning method "Intercomprehension", as well as a web based educational software of learning foreign languages called "Intercom", which is based in this particular method. The application is exclusively based in this learning method, which also develops a teaching method for the promotion of mutual comprehension, supported in common strategies that develop the not-linguistic aspects of receptive faculty. This software is constituted by a number of web interactive activities aiming at the learning of four languages: German, Portuguese, Bulgarian and Greek, while using two guide languages (English and French). The originality of this educational software, is contested in the extension of this learning method over linguistic families while trying to develop not linguistic aspects in the procedure of learning a foreign language.
