Automatic Format Generation Techniques for Network Data Acquisition Systems

Kupferschmidt, Benjamin, Pesciotta, Eric 10 1900 (has links)
ITC/USA 2009 Conference Proceedings / The Forty-Fifth Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2009 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Configuring a modern, high-performance data acquisition system is typically a very timeconsuming and complex process. Any enhancement to the data acquisition setup software that can reduce the amount of time needed to configure the system is extremely useful. Automatic format generation is one of the most useful enhancements to a data acquisition setup application. By using Automatic Format Generation, an instrumentation engineer can significantly reduce the amount of time that is spent configuring the system while simultaneously gaining much greater flexibility in creating sampling formats. This paper discusses several techniques that can be used to generate sampling formats automatically while making highly efficient use of the system's bandwidth. This allows the user to obtain most of the benefits of a hand-tuned, manually created format without spending excessive time creating it. One of the primary techniques that this paper discusses is an enhancement to the commonly used power-of-two rule, for selecting sampling rates. This allows the system to create formats that use a wider variety of rates. The system is also able to handle groups of related measurements that must follow each other sequentially in the sampling format. This paper will also cover a packet based formatting scheme that organizes measurements based on common sampling rates. Each packet contains a set of measurements that are sampled at a particular rate. A key benefit of using an automatic format generation system with this format is the optimization of sampling rates that are used to achieve the best possible match for each measurement's desired sampling rate.

Um mestre da crítica: romantismo, mito e Iluminismo em Walter Benjamin / A master of critique: romanticism, myth, and enlightenment in Walter Benjamin

Oliveira, Everaldo Vanderlei de 27 October 2009 (has links)
O presente trabalho visa investigar os conceitos de crítica e experiência na obra de Walter Benjamin em torno dos anos de 1920, como resultado dos desdobramentos do Programa de 1918, de modo a pôr em relevo seu entrelaçamento com os conceitos de mito e Iluminismo. Para tanto, este trabalho concentra-se no estudo da dissertação de doutoramento do filósofo acerca do romantismo de Iena, bem como seu ensaio crítico sobre As afinidades eletivas de Goethe. Quanto ao primeiro, mostra-se que o conceito de crítica imanente une-se às perspectivas da filosofia e poesia românticas, o que se deve, em especial, ao messianismo presente veladamente no conceito de reflexão. No segundo, tem-se em vista o problema da crítica e da experiência em nova chave, cujos desdobramentos assinalam as relações entre mito e Iluminismo, o que também inclui uma crítica ao eterno retorno, a concepção mítica do tempo. / The present paper aims to investigate the concepts of critique and experience in the work of Walter Benjamin written in the years around 1920, which was derived from On the program of the coming philosophy written in 1918 and thus to highlight their intertwined relationship with the concepts of myth and Enlightenment. To do so, this paper focuses on Benjamin\'s doctorate thesis, The concept of art criticism in German romanticism, as well as on his critical essay on Goethes Elective Affinities. Regarding the first one, we show that the concept of immanent critique joins the perspectives of romantic philosophy and poetics, which is particularly due to the hidden presence of messianism in the concept of reflection. In the second one, we focus on the problem of critique and experience in a new formulation, whose developments show the relations between myth and Enlightenment, which also includes a critique of the eternal return, the mythical concept of time.
