ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / This paper suggests a reconfigurable sensor network (data bus) which is well suited for telemetry mission of rockets and launch vehicles. Reconfiguration of sensors’ channel information can be achieved without additional software and hardware. The proposed network consists of a central unit and multiple remote units with RS-485 data bus. Since those units need only an FPGA and a programmable ROM to be implemented, the network can provide minimum costs and high reliability. And this paper also presents reliability prediction result of a unit based on MIL-HDBK-217F and Monte Carlo simulation.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This article presents a measurement system based on the RS-485 interface. The presented system is an alternative solution for distributed measurement systems, which cannot be built using IEEE-488 interface due to distance limitation between elements of the system. The RS-485 interface is a base for communication between measurement instruments and uses a Master-Slave protocol to exchange data between them. One dedicated master device, usually a PC, controls all slave devices connected to the interface. To control measurement devices SCPI language is used. This solution simplifies communication between measurement devices and allows utilizing the HP-VEE environment to control any SCPI devices connected to the RS-485 network.

My thesis inquires into the reasons behind Proclus' and Boethius' adaptation of discussion more geometrico in their metaphysical works, Elements of Theology and De Hebdomadibus, respectively. My argument is that each philosopher is engaged in a spiritual exercise to the effect that each sought, in his own way, to predispose readers to the anagogical acceptance of profound matters of faith.

This master thesis aimed to develop a prototype of a hardware platform which allowed digital communication as well as DC power to be transmitted over one pair of wires. The prototype was used as a pre-study for Axis Communications AB that wanted a bit rate high enough to transmit digital audio, as well as enough power to supply a set of speakers. The prototype included one circuit to send power and data (master), as well as two receivers (slaves). With this configuration data rates of up to 17 Mbps were achieved as well as an output power of 90 W from master. The data was transmitted on a RS-485 bus type, which was AC coupled to a 48 V DC bias. Because of the AC coupling, the bit stream needed to alternate, therefore Manchester encoded data, or similar, was recommended. The receiver cards included a buck converter to supply the circuits with a stable 5 V DC. The converters needed at least 10 V supply voltage to function, which gave a theoretical max range in cabling when accounting for voltage drop in the cables. For a 0.75 mm² power cord at max allowed current, this range was 500 metres per wire.

Busca-se com isso esclarecer, primeiramente, a influência da matemática no desenvolvimento da filosofia, e, depois, o efeito desta na evolução metodológica daquela, principalmente no que diz respeito ao método analítico, ou hipotético. A pesquisa é norteada pelos testemunhos de Proclus em seus Comentários ao Livro I dos Elementos de Euclides, onde o nome de Platão é associado ao método. Em seguida, verifica-se a descrição dos métodos da análise e síntese feita por Pappus de Alexandria em sua Coleção matemática, a partir da qual são procurados nos diálogos os elementos precursores. A interpretação dos trechos matemáticos dos textos platônicos apoiase nos testemunhos e fragmentos de Hipócrates de Quios, Filolau de Crotona e Árquitas de Tarento, elaborando assim um quadro geral do estado da arte das ciências matemáticas nos séculos V-VI a.C. O seu intuito foi o de contextualizar as principais questões da matemática que teriam atraído o interesse de Platão, levando-o a valer-se da matemática como paradigma metodológico e heurístico a ser adaptado à filosofia. Apresentando uma inovação didática envolta por problemas da imprecisão da linguagem, Platão reformula as doutrinas présocráticas combinadas ao pensamento matemático, cujos desdobramentos são essenciais à organização aristotélica e à formalização Euclidiana / The objective of this thesis is to investigate the relationship between mathematics and philosophy in three Plato‟s work: the Meno, the Phaedo and the Republic. Searching with this to clarify, first, the influence of mathematics in the philosophy‟s development, and then, the effect of this one on the methodological development of that, especially with regard to the analytical or hypothetical method. The research is guided by the Proclus testimony in his Commentary On The First Book of Euclid’s Element, where the name of Plato is associated with the method. Hereupon, is checked the description of the methods of analysis and synthesis made by Pappus of Alexandria in his Mathematical Collection, from which is searched the precursor elements on the dialogues. The interpretation of the mathematical passages of the Platonic texts are based on testimonies and fragments of Hippocrates of Chios, Philolaus of Croton, and Archytas of Tarentum, thus elaborating a general picture of the mathematical sciences state of the art in the centuries V-VI BC. Its scope was to contextualize the main issues of the mathematics that have attracted the Plato‟s interest and that led him to avail himself of that science as a methodological and heuristic paradigm to be adapted to the philosophy. Featuring a didactic innovation surrounded by the imprecision of language problems, Plato reformulates the pre-Socratic doctrines combined to the mathematical thinking, whose developments are essential to Aristotelian organization and Euclidean formalization

Facultad de Filosofía y Humanidades / La recepción creativa de Las Troyanas a manos de Jean Paul Sartre, en constante relación con el hipotexto de Eurípides, es el tema que nos proponemos estudiar en este trabajo. Siguiendo los planteamientos de la teoría de la recepción de Jauss, para quien la obra literaria se define como el resultado del encuentro entre ésta y la recepción que recibe, planteamos que el horizonte de impacto, en tanto sistema que integra el momento de composición de la obra (la época histórica, el contexto sociológico, el contexto autorial y la recepción de la obra en su propio contexto de la Atenas clásica) encuentra profundas afinidades con el horizonte de recepción de Jean Paul Sartre, en relación a la circunstancia histórica específica en que este autor retoma Las Troyanas. Dicho horizonte de recepción considera, tanto el código estético que Sartre introduce en la obra, como el horizonte de los espectadores de su época, y la personal concepción del autor respecto a la misma.

The main focus in this diploma thesis is to analyse ARM microcontroller ATSAM3X8E, audio codec TLV320DAC3203 and CAN / RS485 bus for communication possibly used in device design. This device's purpose is to establish communicatio between elevator cabin and central control unit. Finally, there is design made for this communication device and measurement of CAN bus speed on H05VVH6 cable.

The goal of this thesis is design of platform capable of sensor output emulation. The platform allows to emulate either digital sensors, communicating over UART, SPI, I2C, CAN and RS-485 buses, or analog sensors and sensors with frequency output. Design of computer interface to configure the platform is also a part of the thesis. Special emphasis is placed on the universality and overall user-friendliness of the entire system.
