Introducing computer engineering major for first year students using robotic projects
No full textIn almost every engineering curriculum, an introductory engineering course to enlighten students knowledge on the different engineering disciplines is offered for the freshman students. To better describe the engineering majors and increase students interest, practical projects are often requested to complement the theoretical lectures and concepts covered in these classes. In here we present a robotic-based design project that is designed and developed to serve as one of several final projects available for an introduction to engineering class. The projects require minimal-to-no previous knowledge in programming and attempts to give the students an enjoyable and rewarding experience while being introduced to the computer engineering discipline. The survey results clearly show that the projects enhance students\u27 motivation and improve their interpretation to the engineering design process

El mito de la Revolución. Masas, violencia y sindicalismo en Georges Sorel
No full textEl rojo y el negro, el comunismo y el fascismo. El filósofo Georges Sorel entendido las diferencias y similitudes de ambos ideológico y simbólico de paradigmas, en sus diferentes modalidades, de la de la época de entreguerras. En tanto Sorel vio a una causa común, compartida potencial y similares instrumento revolucionario, destinado, mutatis mutandis, a la destrucción parcial o total de la multiforme liberal–burgués heredado desde el siglo xix. Ambos varias apuestas para la proclamada Redentora de la Revolución Socialista del proletariado, así como las diversas opciones de un nacionalista casi en paralelo Revolución Conservadora, presentó el mismo de la razón histórica. La razón marcado, y tal vez por etapas, por el "símbolo": el símbolo a ser destruidos en su decadencia (la liberal–democracia burguesa) y el símbolo para construir el nuevo socialismo (la violencia revolucionaria). Por esa razón, su polémica doctrinal pluralismo, en el que combinan las propuestas de ambas esferas en el espectro ideológico (supuestamente antagónicos de la historiografía), no era un enigma ni una contradicción, y su propuesta de que el Sindicalismo revolucionario, en el mito de la moral y de trabajo de la violencia, algo totalmente ajeno a su tiempo
Acéphale e a hora presente
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão.Esta dissertação busca, a partir da leitura cruzada de dois periódicos extremamente díspares do imediato pré-segunda-guerra, o francês Acéphale, encabeçado por Georges Bataille e o brasileiro Cadernos da Hora Presente, dirigido por Tasso da Silveira, contribuir para a discussão sobre os impasses das vanguardas artísticas nesse período. Questiona-se aqui a proposta de uma "solução religiosa" para a (des)organização social - ponto comum entre as duas revistas - apontando-se as divergências entre o modo cefálico, sustentado pelos Cadernos, e o acéfalo. Constam também desse volume uma tradução, propositadamente polêmica, dos cinco números de Acéphale e o fichamento completo dos nove números dos Cadernos da Hora Present
Communication-Theoretic Foundations for Optical Receivers Using Dynamically Biased Avalanche Photodiodes
No full textTo meet the demands of the exponential growth in video, voice, data and mobile device traffic over the internet, the telecommunication industry has been moving toward higher speed protocols such as 40-Gb/s and 100-Gb/s. Operations at such high speeds require detectors with optimized internal gain (leading to high sensitivity) to reduce cost. Avalanche photodiodes (APDs) are commonly used photodetectors in many high-speed optical receivers due to their internal optoelectronic gain, which allows the photogenerated current to dominate the thermal noise without the need for optical pre-amplification of the received optical signal. However, the long avalanche buildup time associated with APDs, namely the time needed for all the impact ionizations to settle, has limited their speed and stopped them from meeting the expectations of 40-Gb/s systems. A new approach was proposed recently for operating APDs employing bit-synchronous and periodic dynamic biasing that is expected to reduce the buildup time dramatically. In this dissertation, we present an extensive theoretical modeling and analysis for the novel approach of dynamically biased APD. We develop the first theory for the joint buildup-time and gain statistics for avalanche multiplication under dynamic electric fields. We also develop a theory for filtered shot noise under dynamic biasing, which addresses rigorously the statistic of the dynamically biased APD photocurrent, such as the mean, variance, autocorrelation function, etc. This is used, in turn, to derive analytical expressions for the statistics of the output of the integrate-and-dump optical receiver output. The study is characterized by its ability to predict the performance of a dynamically biased APD-based receiver and to optimize the system parameters to achieve an optimal receiver performance. The exact expressions for the receiver bit-error rate and sensitivity in an on-off keying setting will be extracted using the photocurrent statistics. The sensitivity analysis of the dynamically biased APD-based receiver will specifically capture intersymbol interference (ISI) and dark current, as well as Johnson noise from the trans-impedance amplifier used in the pre-amplification stage of receivers. The results show that operating the APD under dynamic biasing improves the receiver performance beyond its traditional limits operating under static biasing
About this researcher blog on Georges Focus
No full textGeorges Focus, who died in 1708, was a French painter who became crazy at the end of his life. He is the author of a bit more than 130 drawings, accompanied by poems, of great technical quality, made while suffering from psychological disorders. These bizarre works are also marked by great erudition and many precise allusions to contemporary personalities and events. They are a source of micro-history for research on 17th century French society, literature and fine arts. Public domain, htt..
