Measurement of semileptonic branching fractions of B mesons to narrow D-** states - art. no. 1711803

Using the data accumulated in 2002-2004 with the D0 detector in proton-antiproton collisions at the Fermilab Tevatron collider with a center-of-mass energy of 1.96 TeV, the branching fractions of the decays B ->(D) over bar (0)(1)(2420)mu(+)nu(mu)X and B ->(D) over bar (*0)(2)(2460)mu(+)nu(mu)X and their ratio have been measured: B (b) over bar -> B)xB(B -> (D) over bar (0)(1)mu(+)nu(mu)X)xB((D) over bar (0)(1)-> D(*-)pi(+))=[0.087 +/- 0.007(stat)+/- 0.014(syst)]%; B((b) over bar -> B)xB(B ->(D) over bar (*0)(2)mu(+)nu(mu)X)xB((D) over bar (*0)(2)-> D(*-)pi(+))=[0.035 +/- 0.007(stat)+/- 0.008(syst)]% and [B(B ->(D) over bar (*0)(2)mu(+)nu(mu)X)xB((D) over bar (*0)(2)-> D(*-)pi(+))]/[B(B ->(D) over bar (0)(1)mu(+)nu(mu)X)xB((D) over bar (0)(1)-> D(*-)pi(+))]=0.39 +/- 0.09(stat)+/- 0.12(syst), where the charge conjugated states are always implied.

Transient stability analysis of electric energy systems via a fuzzy ART-ARTMAP neural network

This work presents a methodology to analyze transient stability (first oscillation) of electric energy systems, using a neural network based on ART architecture (adaptive resonance theory), named fuzzy ART-ARTMAP neural network for real time applications. The security margin is used as a stability analysis criterion, considering three-phase short circuit faults with a transmission line outage. The neural network operation consists of two fundamental phases: the training and the analysis. The training phase needs a great quantity of processing for the realization, while the analysis phase is effectuated almost without computation effort. This is, therefore the principal purpose to use neural networks for solving complex problems that need fast solutions, as the applications in real time. The ART neural networks have as primordial characteristics the plasticity and the stability, which are essential qualities to the training execution and to an efficient analysis. The fuzzy ART-ARTMAP neural network is proposed seeking a superior performance, in terms of precision and speed, when compared to conventional ARTMAP, and much more when compared to the neural networks that use the training by backpropagation algorithm, which is a benchmark in neural network area.

Electric load forecasting using a fuzzy ART&ARTMAP neural network

This work presents a neural network based on the ART architecture ( adaptive resonance theory), named fuzzy ART& ARTMAP neural network, applied to the electric load-forecasting problem. The neural networks based on the ARTarchitecture have two fundamental characteristics that are extremely important for the network performance ( stability and plasticity), which allow the implementation of continuous training. The fuzzy ART& ARTMAP neural network aims to reduce the imprecision of the forecasting results by a mechanism that separate the analog and binary data, processing them separately. Therefore, this represents a reduction on the processing time and improved quality of the results, when compared to the Back-Propagation neural network, and better to the classical forecasting techniques (ARIMA of Box and Jenkins methods). Finished the training, the fuzzy ART& ARTMAP neural network is capable to forecast electrical loads 24 h in advance. To validate the methodology, data from a Brazilian electric company is used.

Cenografia teatral: uma análise dos aspectos cênicos da peça Bê-a-Bá Brasil - memória, sonho e fantasia

The main objective of this project step is the evolution of scenery matter on the occidental theater media, related to space and technical possibilities of the theatrical building and space on history of contemporary arts. The main point is that scenery must communicate with a specific matter. Something in touch with the plot speeches. Something that makes all the plot elements to communicate. Acting has an specific message to deliver, and that message is what really matter to the viewer of the show. “It’s never late to state that scenery is not a decoration, or just an interior composition. Scenery is not a painting or a sculpture: it’s an integrated art form. It’s never too repetitive to say that scenery is a result from the composition with lights, shadows, shapes, lines and volumes, in balance and on harmony as a whole, that create movement and contrast” (Dias, 2001) On the second step of the project, the objective is to analyze the building process and the scenery aspects of the “Be-a-bá Brasil” show, using illustrations, pictures and analysis data of the context the show was inserted on

Identifique-se: Exposição de Mail Art, uma poética compartilhada

This work refers to a cut of my artistic creation path with some reflections on the subject other. Mail Art has been an alternative trend of art / avant-garde, where communication between artists networks is the goal to be achieved, therefore, from this statement, was approached some historical and particular aspects regarding the post and its contingencies in the art / forefront. Share this moment of academic completion with a postcard exhibition that will take place through the agency of other participating artists. To do so, were invited artists from the theme IDENTIFY UP to send work in postcard size with the exclusive use of the Post Office. The exhibition event will take place in the Gallery of the Art Institute. Participant of other similar projects, I believe I experienced a new role: who calls, organizes and rules.
