Combining Classifiers by Constructive Induction (2007)
. Using multiple classifiers for increasing learning accuracy is an active research area. In this paper we present a new general method for merging classifiers. The basic idea of Cascade...
Implementation of a Library for Modelling in Economics: Design Guidelines (2007)
In this paper we propose some design guidelines for the implementation of a library for computer aided modelling and analysis in economics. We base our approach in object-oriented programming. We...
Control of Search Parameters in Evolutionary Algorithms (2007)
In this paper we present a strategy for automatically adapting the control parameters of an evolutionary algorithm. Its main features consist on its simplicity, and on providing total independence of...
CROSS A Combined Relation-Operation Based Scheduling System (2007)
Jo Ao, Jo~ao M. N, Viegas Luis, M. M. Cust'odio
In this paper a heuristic approach for the project job-shop scheduling problem is presented. The scheduling of a job-shop type production system is generally an NP-complete problem, so the computable...
Stability of Switched Systems with Average Dwell-Time (2007)
Jo Ao, Jo~ao P. Hespanha, A. Stephen Morse
It is shown that switching among stable linear systems results in a stable system provided that switching is "slow-on-the-average." In particular, it is proved that exponential stability is...
(On behalf of the CDF Collaboration) The Tevatron is expected to be most sensitive to the Standard Model Higgs in its associated production with a W or Z boson. The Collider Detector at Fermilab...
INTERVAL COMPUTATION OF VISWANATH'S CONSTANT (2007)
Jo Ao, Batista S. De, Luiz Henrique, De Figueiredo
Abstract. Viswanath has shown that the terms of the random Fibonacci sequences dened by t 1 = t 2 = 1, and t n = tn 1 t n 2 for n> 2, where each sign is chosen randomly, increase exponentially in...
: We consider the Schrodinger equation for a class of two-level atoms in a quasi-periodic external field for large coupling, i.e., for which the energy difference 2ffl between the unperturbed levels...
What Can Be Done with an Uncalibrated Stereo System? (1998)
Jo Ao, Zachary Dodds, Gregory D. Hager, A. S. Morse
Over the last several years, there has been an increasing appreciation of the impact of control architecture on the accuracy of visual servoing systems. In particular, it is generally acknowledged...
Embedding Learning in Behaviour-Based Architectures: A Conceptual Approach (1997)
: This paper addresses the identification of the key elements to be present in a generic, behaviour -based architecture for robot control. These elements include the definition of behaviours aiming...
A Behaviour-Based Kernel Architecture for Robot Control (1997)
: This paper identifies the basic building blocks in a behaviour-based architecture for robot control. The major contribution of the paper is the definition of a state space able to embed semantic...
