Particle swarm optimization (PSO) is a population-based swarm intelligence algorithm that shares many similarities with evolutionary computation techniques. However, the PSO is driven by the simulation of a social psychological metaphor motivated by collective behaviours of bird and other social organisms instead of the survival of the fittest individual. Inspired by the classical PSO method and quantum mechanics theories, this work presents new Quantum-behaved PSO (QPSO) approaches using mutation operator with exponential probability distribution. The simulation results demonstrate good performance of the QPSO in solving a well-studied continuous optimization problem of mechanical engineering design. Copyright © 2006 by ASME.

The present work is focused on the study of indoor thermal comfort control problem in buildings equipped with heating systems. The occupants' thermal comfort sensation is addressed here by a comfort index known as PMV (Predict Mean Vote). In this context, two control algorithms are proposed by using only-one-actuator system associated to the heating system. The methods are based on the model predictive control scheme and on the improvement of the PMV index together with energy minimization. Simulation results - obtained by using the weather data file for the city of Curitiba, Brazil - for two case studies: i ) variations between low and moderate occupants metabolic rates and ii) variations between moderate and high occupants metabolic rates are presented to validate the proposed methodology in terms of room air temperature, relative humidity and PMV control.

Society of Plastics Engineers Annual Technical Conference 2006, ANTEC 2006

Injection Molding (IM) is the most important process for mass-producing plastic products. The difficulty of optimizing an IM process is that the performance measures (PMs), usually show conflicting behavior. The aim of this work is to demonstrate a method utilizing CAE, statistical testing, artificial neural networks (ANNs), and data envelopment analysis (DEA) to find the best compromises between multiple PMs and their variability. Two case studies are presented. A case study based on a virtual part is presented in detail in order to illustrate this method. The second case study is experimentally based, using the American Society of Testing Materials (ASTM) mold, to illustrate how this approach applies when only experimental results are available.

113th Annual ASEE Conference and Exposition, 2006

While the pedagogy of Service-Learning (S-L) has been applied beneficially in a variety of disciplines, only recently have engineering departments begun to adopt the practice of integrating academically-relevant community service projects into classes and, in doing so, it is most common to offer service-oriented projects in elective classes. However, the University of Massachusetts Lowell and the Massachusetts Institute of Technology have independently begun to develop S-L programs in engineering fields that work specifically to use the pedagogy in the core curriculum of the discipline. While the two universities and educational programs are distinct, the approach to S-L has been reasonably similar, and faculty and staff from each school have used common tools and methods to assess certain aspects of the integration from student and faculty perspectives. From surveys used at both of the schools (almost 760 pre-surveys and 680 post-surveys administered in the 04-05 academic year), a key finding was that student opinion changed significantly regarding the relationship between engineering and societal problems;students developed the belief that engineers should apply their skills to solve social problems. Additionally, both institutions surveyed the engineering faculty about their attitudes toward S-L and found the majority of faculty showed considerable interest in the concept. Overall, these findings show promise for integrating S-L into core engineering curriculums. © American Society for engineering Education, 2006.

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.

Regulations governing the discharge of sewage from ships have been in force since the early 1970's. In response, the marine industry has developed ever more complex systems and processes for managing these wastes. The first compliance method involved holding wastes until they could be legally discharged;as technology advanced, treatment systems were developed and installed to enable discharge within regulated waters. As the size and number of ships as increased with maturation of the ocean tourism business, more restrictive regulations have been enacted to minimize the impact on sensitive waters. The trend is toward increasing regulation of both sewage and graywater. The most recent action occurred on 12 October 2005 when the Governor of California signed into law Senate Bill 771 regulating most ship liquid discharges within state waters. This paper describes the development of an innovative advanced wastewater treatment technology, based on advanced oxidation, bearing in mind the lessons learned from systems developed by industry over the past thirty years.

This paper investigates vision based robot control based on a receding horizon control strategy, as a first step for a predictive visual feedback control. Firstly, the brief summary of the 3D dynamic visual feedback system with eye-in-hand configuration is given. Next, a stabilizing receding horizon control for the 3D dynamic visual feedback system, a highly nonlinear and relatively fast system, is proposed. The stability of the receding horizon control scheme is guaranteed by using the terminal cost derived from an energy function of the visual feedback system. Furthermore, simulation results are assessed with respect to the stability and the performance

In this study, a new micro electroporation (EP) cell chip with three-dimensional (3D) electrodes was fabricated by means of MEMS technology, and tested on HeLa cervical cancer cells. Large statistical data of loading efficiency for five different size molecules and cell viability were determined under various voltage and duration time. Based on more than 2000 single cell measurements, the critical size of molecule was found to be approximately 40 kD. © 2006 Society for Chemistry and Micro-Nano systems.
