Generalized Multivariable Control of Discrete Event Systems in Dioids
Found in: Discrete Event Systems, International Workshop on
By Ricardo Lüders, Rafael Santos-Mendes
Issue Date:October 2002
pp. 197
Dioids are algebraic structures suitable to represent a timed event graph by means of a linear state-space or transfer function model, where synchronization of events can be described. This paper proposes a model reference control strategy under partial ob...
Evaluating the Effects of Branch Prediction Accuracy on the Performance of SMT Architectures
Found in: Parallel, Distributed, and Network-Based Processing, Euromicro Conference on
By Ronaldo Gonçalves, Maurício Pilla, Guilherme Pizzol, Tatiana Santos, Philippe Navaux, Rafael Santos
Issue Date:February 2001
pp. 355
Branch instruction occurrence reduces the parallelism exploited from the source code of single-threaded applications. In order to reduce the branch penalty, several branch predictor techniques have been proposed. Branch predictors allow the fetch unit to c...
Ten Years of SkyServer I: Tracking Web and SQL e-Science Usage
Found in: Computing in Science & Engineering
By M. Raddick,Ani Thakar,Rafael Santos,Alexender S. Szalay
Issue Date:March 2014
pp. 1
We describe how we collect and analyze the complete record of more than ten years of web hits and SQL queries to SkyServer, the primary catalog data portal of the Sloan Digital Sky Survey (SDSS) that makes multiple Terabytes of astronomy data available to ...
Citizen Science-based Labeling of Imprecisely Segmented Images: Case Study and Preliminary Results
Found in: Sistemas Colaborativos, Simpósio Brasilerio de
By Marinalva Dias Soares, Rafael Santos, Nandamudi Vijaykumar, Luciano Dutra
Issue Date:October 2010
pp. 87-94
One of the most important objectives of remote sensing image processing is the identification of objects on an image. Automatic and correct object identification is hard to achieve, since the intermediate steps (including segmentation) may yield imprecise ...

By Luciano Godoy Fagundes, Rafael Santos
Issue Date:September 2010
pp. 34-45
The iPhone is one of the most powerful, complete and versatile portable phones on the market. There are presently more than 150.000 applications available for the iPhone, and its users had downloaded more than three billion applications so far. The iPhone ...
QoS-Broker for Transactional Workloads
Found in: Advanced Information Networking and Applications Workshops, International Conference on
By Celso Rafael Santos, Joao Costa, Pedro Furtado
Issue Date:May 2007
pp. 594-599
Traditional database servers try to accommodate requests as fast as possible, which can be described as a best effort approach. However, different access items may have different quality-of-service (QoS) requirements. Therefore, it is important to provide ...
