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.

In this paper, a diagnostics and root-cause analysis scheme for real-time monitoring of process quality of pull-type fastening operations is presented. The proposed approach encompasses (1) integrating a strain gage, an LVDT (Linear Variable Differential Transducer), a pressure sensor, and a mote on a pull-type pneumatic tool;(2) monitoring process parameters coming from embedded sensors communicated wirelessly via the mote and generating process signatures in real-time;and (3) detecting anomalies in real-time in the process signatures for quality problems related to the grip length deviation in pull-type fastening operations. A feature extraction-based diagnostic methodology is employed to make decisions in terms of grip length deviations in the form of normal grip, over grip, and under grip. The process signature of strain-over-displacement versus displacement has shown unique features that are extracted to determine the quality of the fastening process. In addition, air pressure is also continuously monitored in real-time during the process since it also affects the quality of the fastening operation. The overall architecture has been implemented on a Huck45 pull-type tool, which is a hand-held pneumatic fastening tool used extensively in the aerospace industry, with lock-bolt fasteners. The prototype has been tested under a variety of experimental settings in order to verify its effectiveness and validate its performance over a wide range of different sheet metal thicknesses used for fastening. The experiments have shown that the proposed approach is successful, with an accuracy of over 96%, in determining the quality of fastening operations and in communicating the quality information in real-time using a wireless network to a server. Overall, the proposed architecture has merits to (1) detect quality problems in real-time during the fastening process and (2) reduce post-process inspection, thereby improving quality while reducing cost. In addition, the propose

It is dangerous that a technician the inner parts of an oil tanker for defects and conditions because of many harmful gases, complex structures, etc. However, these inspections are necessary to many oil tankers of old years. In this reason, we proposed the fundamental techniques of mobile robot for inspection of CAS in oil tanker. The developed CAS inspection mobile robot has four modules, a measurement module of oil tanker's thickness, a corrosion inspection module, a climbing module of the surface on a wall, and a monitoring module. In order to getting over at a right angled path, the driving control algorithm was developed. And, magnetic wheels were used to move the surface of a wall. This study constructed a communication network (Bluetooth) and the monitoring program to operate the developed mobile robot from remote sites. In order to evaluate the inspection ability, the experiments using developed mobile robot have been conducted.

IIE Annual Conference and Expo 2007 - Industrial engineering's Critical Role in a Flat World

Broaching is one of the most recognized machining processes that can yield high productivity and high quality when applied properly. One big disadvantage of broaching is that all process parameters, except cutting speed, are built into the broaching tools. Therefore, it is not possible to modify the cutting conditions during the process once the tool is manufactured. Optimal design of broaching tools has a significant impact to increase the productivity and to obtain high quality products. In this paper, an optimization model for broaching design is presented. The model results in a non-linear non-convex optimization problem. Analysis of the model structure indicates that the model can be decomposed into smaller problems. The model is applied on a turbine disc broaching problem which is considered as one of the most complex broaching operations.

114th Annual ASEE Conference and Exposition, 2007

作者： Newberry, Byron Baylor University United States Department of Mechanical Engineering Baylor University United States Baylor Great Texts Program United States Texas Tech University University of Texas United States Japan IEEE Society for Social Implications of Technology United States L3 Communications Integrated Systems

In his book Designing Engineers, engineer Louis Bucciarelli answers the question "Do you know how your telephone works?" with the rhetorical rebuttal, "Does anyone know how their telephone works?" At first pass, we might be inclined to assume that engineers, scientists, or computer scientists are by default technologically literate - if anyone knows how the telephone works, surely it is them. But the intent of Bucciarelli's question is to point to a deeper ambiguity about what is means to "know" how something works, even in the case of a technical expert. Essentially what he is asking is "Is anyone really technologically literate?" This is the question I will explore philosophically in this paper, with particular focus on the technological literacy of technological professionals such as engineers. I will begin by examining the definitions of, and criteria for, technological literacy provided by the NAE report Technically Speaking. I will examine the extent to which those criteria might be satisfied, both for lay people as well as technological professionals. The Technically Speaking report describes some general obstacles to achieving technological literacy. I will discuss these challenges and offer some additional ones, including some to which technological professional contribute, and others which primarily affect technological professionals. I will close by offering some general observations from an engineer's perspective on the definition and goals of technological literacy. © American Society for engineering Education, 2007.

The goal of this special session is to explore what engineering education might be like if it were done from a feminist perspective, and how this new vision might influence the profession and society. Feminist perspectives are understood broadly to recognize the connectedness of all forms of social injustice. Thus feminist visions of engineering might address a broad set of concerns such as militarism, racism, and global economic inequality as well as sexism and heterosexism. Outcomes include concrete ideas for future research and institutional transformation, collaboration and mutual support of one another's efforts.
