Particle swarm optimization (PSO) is a population-based stochastic optimization technique, originally developed by Eberhart and Kennedy, inspired by simulation of a social psychological metaphor instead of the survival of the fittest individual. In PSO, the system (swarm) is initialized with a population of random solutions (particles) and searches for optima using cognitive and social factors by updating generations. PSO has been successfully applied to a wide range of applications, mainly in solving continuous nonlinear optimization problems. Based on the PSO and chaos theories, this paper discusses the use of a chaotic PSO approach hybridized with an Implicit Filtering (IF) technique to optimize performance of economic dispatch problems. The chaotic PSO with chaos sequences is the global optimizer and the IF is used to fine-tune the chaotic PSO run in sequential manner. The hybrid methodology is validated for a test system consisting of 13 thermal units whose incremental fuel cost function takes into account the valve-point loading effects. © 2007 IEEE.

Soil Stratification methods are used to estimate soil geoelectrical parameters. Several stratification methods are available, but reducing the error estimation introduced by such methods still poses as a challenge. The purpose of this work is to present a heuristic algorithm applied to the optimization of geoelectrical prospection process. The goal is to estimate soil parameters, such as the amount of layers, thickness and resistivity of each layer in an optimal and automated manner. The algorithm consists of analyzing the sensitivity of sampling space parameters. The propose methodology shows error reduction above 75% between the experimental and theoretical curves of the analyzed soils. The results are presented and discussed. © 2016 IEEE.

Particle swarm optimization (PSO) is a population-based swarm intelligence algorithm driven by the simulation of a social psychological metaphor instead of the survival of the fittest individual. Based on the swarm intelligence theory, this paper discusses the use of PSO approaches using an operator and based on the Gaussian probability distribution function as a population space of a cultural algorithm, called cultural Gaussian PSO (GPSO-CA). Cultural algorithms are mechanisms that incorporate domain knowledge obtained during the evolutionary process, which increase the efficiency of the search process. These approaches are employed in a well-studied continuous optimization problem of mechanical engineering design. © 2006 IEEE.

SaaS (Software as a Service) has become one of the fastest-growing innovative fields of the IT sector. Yet, as any other software intensive organizations, SaaS providers also need to deliver the service quality they offer. And, although, today exist a multitude of software quality models, so far, a specific adaptation does not exist to the SaaS context. Therefore, we present the results of our research on discovering software process and product quality criteria in the SaaS scenario. We adopted a research methodology, including, domain analysis, stakeholders interviews and literature review to elicit quality criteria and a survey to validate and prioritize the identified criteria. Such a set of identified quality criteria may help service clients to select providers as well as serve as a basis for a mapping relevant software process areas and best practices in order to adapt existing capability/maturity models and standards to this specific domain. © 2010 Springer-Verlag.

Recently, evolutionary algorithms (e.g. genetic algorithms, evolutionary programming, and evolution strategies) have proven to be useful tools for the optimization of difficult problems in electromagnetics. Differential evolution (DE) is one comparatively simple variant of an evolutionary algorithm using floating-point encoding and few control parameters. This work presents improved DE algorithms based on linearly time varying control parameters, sinusoidal functions, and diversity analysis of population. © 2006 IEEE.

Minimum Realization Tuning Strategy for Dynamic Matrix Control

IFAC Proceedings Volumes 2014年第3期47卷 1314-1319页

作者： Daniel C. Jeronymo Antonio A.R. Coelho Automation and Systems Engineering Graduate Program Federal University of Santa Catarina UFSC Florianópolis SC Brazil

In this paper autotuning and self-tuning methods for Dynamic Matrix Control (DMC) are presented with application to single-input single-output (SISO) processes which can be approximated by a first-order-plus-dead-time model. In order to validate the method a nonlinear control valve system described by a Wiener process is simulated. This process was identified by a Hammerstein model and controlled by DMC with output compensator. The proposed tuning methods have its performance compared to another standard method found in literature, showing more conservative results regarding smoothness of the control action while maintaining adequate performance on set-point tracking.

The development of artificial intelligence(AI) and the mining of biomedical data complement each other. From the direct use of computer vision results to analyze medical images for disease screening, to now integrating biological knowledge into models and even accelerating the development of new AI based on biological discoveries, the boundaries of both are constantly expanding, and their connections are becoming closer.

Mandatory and discretionary policies for CORBA security

Journal of Network and systems Management 2005年第3期13卷 309-328页

This paper proposes extending the CORBA (Common Object Request Broker Architecture) security model to make possible the use of mandatory policies and policy management in distributed applications. Mandatory policies and a policy service were proposed for insertion in the JaCoWeb Project, which is developing an authorization scheme for large-scale networks based on CORBA security standards. In this paper, there is a combination of client-side and server-side access control, in a single domain. Our mandatory control is carried out on the level of ORB (Object Request Broker), on the client side, preventing, in unauthorized accesses, the emission of the corresponding requisition, the associated processing on the server and also, the generation of new requests through this unauthorized processing. In this paper, operations of security management not currently included in the OMG standards are also proposed. The paper further presents implementation results and an evaluation of these results based on common criteria. © 2005 Springer Science+Business Media, Inc.
