Design and Implementation of the PBIW Instruction Decoder in a Softcore Embedded Processor
Found in: 2012 13th Symposium on Computer Systems - XIII Simp sio de Sistemas Computacionais (WSCAD-SSC)
By Renan Marks,Felipe Araujo,Renato Santos,Felipe Yonehara,Ricardo Santos
Issue Date:October 2012
pp. 110-117
This paper presents the PBIW (Pattern Based Instruction Word) instruction encoding technique on the \RVEX embedded soft core processor. The PBIW encoding technique maps the assembly generated by a compiler into an encoding scheme of a target processor. The...
 
Multiagent Systems Modeling Using GPUs -- A Case Study of the Human Immune System
Found in: 2012 13th Symposium on Computer Systems - XIII Simp sio de Sistemas Computacionais (WSCAD-SSC)
By Oberlan Christo Romao,Luis Eduardo de Souza Amorim,Ricardo Santos Ferreira,Maurilio de Araujo Possi,Alcione de Paiva Oliveira
Issue Date:October 2012
pp. 234-241
Computer Science development plays an important role to understand natural phenomena. Its advance has impacted on studies results from many areas such as Biology and Medicine. Agent-based Models (ABM) are an alternative to model and to simulate natural phe...
 
Personality, Emotion, and Mood in Agent-Based Group Decision Making
Found in: IEEE Intelligent Systems
By Ricardo Santos,Goreti Marreiros,Carlos Ramos,José Neves,José Bulas-Cruz
Issue Date:November 2011
pp. 58-66
Incorporating affective characteristics (such as personality, emotion, and mood) in an agent-based group decision-support system can help improve the negotiation process.
 
Context-Aware Emotion-Based Model for Group Decision Making
Found in: IEEE Intelligent Systems
By Goreti Marreiros, Ricardo Santos, Carlos Ramos, José Neves
Issue Date:March 2010
pp. 31-39
<p>This context-aware emotion-based model can help design intelligent agents for group decision-making processes. Experiments show that agents with emotional awareness reach agreement more quickly than those without it.</p>
 
The UBIRIS.v2: A Database of Visible Wavelength Iris Images Captured On-the-Move and At-a-Distance
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Hugo Proença, Sílvio Filipe, Ricardo Santos, João Oliveira, Luís A. Alexandre
Issue Date:August 2010
pp. 1529-1535
The iris is regarded as one of the most useful traits for biometric recognition and the dissemination of nationwide iris-based recognition systems is imminent. However, currently deployed systems rely on heavy imaging constraints to capture near infrared i...
 
2D-VLIW: An Architecture Based on the Geometry of Computation
Found in: Application-Specific Systems, Architectures and Processors, IEEE International Conference on
By Ricardo Santos, Rodolfo Azevedo, Guido Araujo
Issue Date:September 2006
pp. 87-94
This work proposes a new architecture and execution model called 2D-VLIW. This architecture adopts an execution model based on large pieces of computation running over a matrix of functional units connected by a set of local register spread across the matr...
 
An implementation of the multi-geo routing protocol for wireless sensor networks using quadtrees
Found in: Proceedings of the 6th ACM symposium on Performance evaluation of wireless ad hoc, sensor, and ubiquitous networks (PE-WASUN '09)
By Carlos Castro Goulart, Mauro Nacif Rocha, Ricardo Santos Ferreira, Vitor Barbosa C. Souza
Issue Date:October 2009
pp. 23-26
This work presents a modified version of Multi-Geo, an adaptive hybrid protocol for Wireless Sensor Network (WSN) whose behavior is based on the network traffic in a given time. It is set to a reactive behavior when the frequency of events is low or it is ...
