Optimization Of The Fuzzy Logic Controller For An Autonomous Uav, Jon C. Ervin, Sema E. Alptekin, Dianne J. Deturris
Optimization Of The Fuzzy Logic Controller For An Autonomous Uav, Jon C. Ervin, Sema E. Alptekin, Dianne J. Deturris
Industrial and Manufacturing Engineering
In this paper, we describe the optimization of membership functions in an application employing a hierarchical Fuzzy Logic Controller. The size of the rule base is made manageable by using a unique formulation, known as Combs method, to help control the problem of ‘exponential rule expansion’. The optimization is performed using a steady state genetic algorithm with a dynamic fitness function. The controller being developed is designed to fly a small, autonomous parafoil, suitable for short-range reconnaissance and land survey applications. The optimization process is performed in the Matlab/Simulink software environment and incorporates fuzzy logic modules developed in the Matlab …
Stability Analysis For Forging Of Porous Bodies, Xuan Wang, Eugene Olevsky, Alain Molinari
Stability Analysis For Forging Of Porous Bodies, Xuan Wang, Eugene Olevsky, Alain Molinari
Industrial and Manufacturing Engineering
The continuum theory of sintering is used for the analysis of the stability of forging of a cylindrical powder specimen. The constitutive properties of the powder material are assumed to follow a power-law creep relationship. Temperature-coupled linear non-uniform stability analyses are carried out. Stability maps are obtained for forging of copper powder components.

The Effectiveness Analysis Of The Online Tools For Engineering Faculty Needs, Ismail Fidan, Jianbiao Pan, Leijun Li
Industrial and Manufacturing Engineering
As the use of Internet is increasing dramatically, many faculty members are using it in their teaching, research, and services. The Internet also provides faculty easy access to employee benefits and other information. Many universities are using or plan to use online teaching. Lately, many editorial and funding agencies have also started to initiate online review and decision-making system. These systems have eased the burden on both reviewers and agencies. In this study, a survey was prepared and conducted to investigate the effectiveness of the online tools for faculty needs in authors’ institutions and some other United States universities. The …

Industrial and Manufacturing Engineering
This work is a continuation of Zadeh’s research on Precisiated Natural language. Precisiated Natural Language (PNL) provides a system for computation and deduction of propositions expressed in a natural language. The importance of PNL for economics is discussed. The improved process of PNL is presented using a real world example from economics.
Development Of A Flying Eye: A Project-Based Learning Experience, Sema E. Alptekin, Dianne Deturris, Daniel J. Macy, Jon E. Ervin
Development Of A Flying Eye: A Project-Based Learning Experience, Sema E. Alptekin, Dianne Deturris, Daniel J. Macy, Jon E. Ervin
Industrial and Manufacturing Engineering
The paper describes the design for manufacturability of a prototype product as part of a manufacturing engineering capstone course. The product chosen was a vertically launched unmanned aerial vehicle (UAV)—the “Flying Eye.” The Flying Eye is an autonomous parafoil surveillance platform quipped with sensors, controllers, mechanical components, and software. Once the autonomous UAV is deployed, it is designed to follow a predetermined flight path down to the ground. The design effort of the prototype device took place over a three-year period as a collaborative effort between the Aerospace Engineering and Industrial and Manufacturing Engineering departments at California Polytechnic State University. …

There is an increasing demand for replacing tin-lead (Sn/Pb) solders with lead-free solders in the electronics industry due to health and environmental concerns. The European Union recently passed a law to ban the use of lead in electronic products. The ban will go into effect in July of 2006. The Japanese electronics industry has worked to eliminate lead from consumer electronic products for several years. Although currently there are no specific regulations banning lead in electronics devices in the United States, many companies and consortiums are working on lead-free solder initiatives including Intel, Motorola, Agilent Technologies, General Electric, Boeing, NEMI …

Machine Vision Course For Manufacturing Engineering Undergraduate Students, Jose Macedo, Kurt Colvin, Daniel Waldorf
Industrial and Manufacturing Engineering
A 10-week course was designed with funding from the Society of Manufacturing Engineers (SME) and input from industry representatives, to offer upper division engineering students a course on advanced automation. The objective was to provide engineering students theoretical and hands-on practical experience with automation technologies that will be of prime importance over the next decade: data acquisition and instrumentation, machine vision and motion control. This paper describes the machine vision portion of that class. It describes important concepts, hands-on equipment, and labs developed for this course, as well as examples of student projects from Spring Quarter, 2004. The course and …
