A Heuristic Algorithm To Generate Test Program Sequences For Moving Probe Electronic Test Equipment, Bertha M. Arteta Oct 2001

A Heuristic Algorithm To Generate Test Program Sequences For Moving Probe Electronic Test Equipment, Bertha M. Arteta

FIU Electronic Theses and Dissertations

The electronics industry, is experiencing two trends one of which is the drive towards miniaturization of electronic products. The in-circuit testing predominantly used for continuity testing of printed circuit boards (PCB) can no longer meet the demands of smaller size circuits. This has lead to the development of moving probe testing equipment. Moving Probe Test opens up the opportunity to test PCBs where the test points are on a small pitch (distance between points). However, since the test uses probes that move sequentially to perform the test, the total test time is much greater than traditional in-circuit test. While significant ...

Computer-Aided Engineering For Tool Design In Manufacturing Engineering Curriculum, Daniel J. Waldorf Jun 2001

Computer-Aided Engineering For Tool Design In Manufacturing Engineering Curriculum, Daniel J. Waldorf

Industrial and Manufacturing Engineering

At Cal Poly – San Luis Obispo, a variety of tool design issues are covered in a junior-level manufacturing engineering course called Tool Engineering. In the course, designing fixtures – for any process – is a major component of the content. The process of designing a fixture is similar to the method a mechanical engineer would use to design a new product. The course is therefore an excellent opportunity to teach design principles to manufacturing engineers. This project involves an attempt to introduce computer-aided methods, including the finite element method (FEM), for analysis of tool design into the Tool Engineering course. The approach ...

Teaching Factory, Sema E. Alptekin, Reza Pouraghabagher, Patricia Mcquaid, Daniel Waldorf

Industrial and Manufacturing Engineering

Academia must develop a new approach to teaching in order to better prepare engineering students to function efficiently and adjust readily within the framework of the factories in the real world. Some engineering programs emphasize theory, while others emphasize application as isolated blocks. The "Teaching Factory" being developed at Cal Poly combines both theory and applications. It makes use of state-of-the-art industrial grade production equipment, computer hardware and software in the form of the following two systems: 1) a functioning "real" factory hardware environment, and 2) a Production Planning and Control Center.

The Impact Of Surface Errors On The Location And Orientation Of A Cylindrical Workpiece In A Fixture, Supapan Sangnui, Frank E. Peters May 2001

The Impact Of Surface Errors On The Location And Orientation Of A Cylindrical Workpiece In A Fixture, Supapan Sangnui, Frank E. Peters

Industrial and Manufacturing Systems Engineering Publications

Surface error at the contact region is one factor that contributes to the displacement of the workpiece in a fixture. This work employs the Newton-Raphson technique to develop a mathematical model that predicts the impact of surface errors on the location and orientation of a cylindrical workpiece. Model validation and measurement analysis were conducted to verify the proposed mathematical model. An experimental fixture and workpiece were developed to simulate the effect of surface errors on the placement of a workpiece. The study showed that the numerical model is reliable in predicting the behavior of the workpiece.


Maximum Acceptable Oral Reading Speed For Voice Input Systems, Nirari M. Oda Apr 2001

Maximum Acceptable Oral Reading Speed For Voice Input Systems, Nirari M. Oda

Master's Theses

The objective of this thesis was to study the effect of vocal duration period and background noise on psychophysical oral reading speed. Ten healthy white males (21-28 years old) were used as subjects. Experiment one was designed to determine Maximum Acceptable Oral Reading Speed (MAORS) for an 8-hour period using psychophysical methodology. Results indicate that 114 words/min was an acceptable oral reading rate for an 8-hour day. Furthermore, 2 hours and 20 minutes is an acceptable testing period ( equivalent to the 8-hour day). Acoustical and physiological variables support these findings. Experiment two was designed to study the effect of ...


Entrance Capacity Of An Automated Highway System, Randolph W. Hall, Ali Nowroozi, Jacob Tsao Jan 2001

Entrance Capacity Of An Automated Highway System, Randolph W. Hall, Ali Nowroozi, Jacob Tsao

Faculty Publications

This paper evaluates the entrance capacity and queueing delay for Automated Highway Systems through use of simulations and analytical modeling. Queueing statistics are also used to determine the sustainable capacity of alternative concepts, taking trip length distribution and spacing between ramps into consideration. Based on safety-spacing headways (produced in a separate analysis), the most promising concept utilizes platoons both on the highway and on on-ramps. However, it is unclear whether comparable capacity can be achieved on exit, when vehicles must be decoupled from their platoons, and whether it is safe for vehicles to enter the highway in closely spaced platoons ...

Industrial and Management Systems Engineering Faculty Publications

This paper presents an integrated simulation and activity-based management approach for determining the best sequencing scheme for processing a part family through a manufacturing cell. The integration is illustrated on a loop or U-shaped manufacturing cell and a part family consisting of four part types (A, B, C, and D). Production requirements for the cell demand that part batches be processed one type at a time. For example, all part A’s are processed until weekly demand is met, then part B’s, etc. The objective of this example is to determine the best part sequence (e.g., ABCD, DCBA ...


Combining Activity-Based Costing With The Simulation Of A Cellular Manufacturing System, Paul Savory, Robert Williams, Rodney Rassmuseun Jan 2001

Combining Activity-Based Costing With The Simulation Of A Cellular Manufacturing System, Paul Savory, Robert Williams, Rodney Rassmuseun

Industrial and Management Systems Engineering Faculty Publications

Discrete-event simulation is one of the most effective techniques for analyzing a manufacturing system. Unfortunately, little attention is given to using simulation models to estimate the economic impact of a proposed system configuration. This paper defines how activity-based costing (ABC) concepts can be incorporated into a discrete-event simulation model. Special emphasis is on demonstrating how decision making can be aided by having the simulation create a detailed “Bill of Activity” describing costs associated with manufacturing a part. The integration of ABC and simulation is illustrated by evaluating the impact of a proposed manufacturing cell configuration. The additional costing information aids ...

Virtual Classroom For Teaching The Economics Of Engineering Design, Janis P. Terpenny, Kimberly Sward Jan 2001

Virtual Classroom For Teaching The Economics Of Engineering Design, Janis P. Terpenny, Kimberly Sward

Janis P. Terpenny

As decision-makers, engineers must be knowledgeable and competent in multiple aspects of design. Engineering is more than a problem solving activity focusing on simply the expected performance of designed artifacts. Consideration must also be given to the economic consequences of design decisions on life-cycle issues. A major challenge to undergraduate engineering education is to increase student competency in the economic elements that are such a critical part of the engineering process. Many believe that success in this endeavor requires new methods and materials that actively engage students in learning, are more closely aligned with engineering decision-making, and include real-world problems ...


Development Programs For One-Shot Systems Using Multiple-State Design Reliability Models , Suntichai Shevasuthisilp Jan 2001

Development Programs For One-Shot Systems Using Multiple-State Design Reliability Models , Suntichai Shevasuthisilp

Retrospective Theses and Dissertations

Design reliability at the beginning of a product development program is typically low and development costs account for a large proportion of the total product cost. Our research focuses on how to conduct "development programs" (series of tests and redesigns) to both achieve high final design reliability and spend as little of a fixed budget as possible on development. Multiple-state reliability models are used. We consider one-shot systems, which are destroyed at first use or during testing. Dynamic programming is used to identify the best test-and-redesign strategy and is shown to presently be computationally feasible for at least 5 state ...

The construction industry lags behind other industries in adopting new information technologies (ITs). The current construction procedures used to transfer data need to be updated. The most common data capture technologies are bar code and radio frequency identification (RFID) tagging. Although bar code and RFID systems are quite different, they might accomplish the same tasks.;In fact, so many new data capture technologies now exist that industry managers are often perplexed when they plan a new system. This research develops a decision tool that enables decision makers in the construction industry to select the most appropriate data capturing technology for ...


Interval Estimators Of Parameters For Normal One Sample And Balanced One-Way Random Effects Models When Data Are Rounded , Chiang-Sheng Lee Jan 2001

Interval Estimators Of Parameters For Normal One Sample And Balanced One-Way Random Effects Models When Data Are Rounded , Chiang-Sheng Lee

Retrospective Theses and Dissertations

In standard statistical analysis, data are typically assumed to be essentially exact. But in fact, all real data are reported to some smallest unit of measure related to the precision of the device used to produce them. We might call such data "rounded" because they are really obtained by "rounding to something." We first discuss the interval estimation of the parameters mu and sigma, when a single rounded sample comes from the N(mu, sigma 2) distribution with both parameters unknown. Then we discuss the interval estimation of variance components sigma and sigmatau if rounded data are from a balanced ...


Statistical Modeling And Design For Cmm-Type Data Locating Known Two-Dimensional Geometries , Dewi Rahardja Jan 2001

Statistical Modeling And Design For Cmm-Type Data Locating Known Two-Dimensional Geometries , Dewi Rahardja

Retrospective Theses and Dissertations

This research was motivated by a problem from a car-manufacturer that needed to compare/analyze two hood assembly fixtures. The consistency of the car hood placement was examined for both fixtures. A "constant width" gap between the hood and the car's body is preferred. A "wide" gap at one point and a "narrow" gap at another constitutes a bad quality placement of the car hood, and will affect customer satisfaction.;3-D data were taken using a Coordinate Measuring Machine (CMM) with 12 (fixed) probe paths to the hood. For each fixture, ten "12-dimensional" vectors were taken and the original ...

Retrospective Theses and Dissertations

Three in-process surface roughness prediction (ISRP) systems using linear multiple regression, fuzzy logic, and fuzzy nets algorisms, respectively, were developed to allow the prediction of real time surface roughness of a work piece on a turning operation. The surface roughness is predicted from feed rate, spindle speed, depth of cut, and machining vibration that is detected and collected by an accelerometer.;Two groups of data were collected for two cutters with nose radii of 0.016 and 0.031 inches, respective. A total of 162 training data sets and 54 testing data sets for each cutter were applied to train ...


Generation Planning For Electric Power Utilities Under Market Uncertainties: A Real Options Approach , Chung-Hsiao Wang Jan 2001

Generation Planning For Electric Power Utilities Under Market Uncertainties: A Real Options Approach , Chung-Hsiao Wang

Retrospective Theses and Dissertations

The generation business in the U.S. is currently undergoing a transition from a regulated monopoly toward an uncertain, competitive market. Under the competitive market, the price of electric power as well as the corresponding revenue may be much less certain than before. These market uncertainties have increased the significance of two critical factors in generation planning. These factors are financial risks and managerial flexibilities.;In order to quantitatively and objectively address these two factors in generation planning, in this dissertation, we design and analyze a series of mathematical models based on the real options approach for generation planning. Hence ...

Use Of Incremental Adaptation And Habituation Regimens For Mitigating Optokinetic Side-Effects, David A. Graeber Jan 2001

Use Of Incremental Adaptation And Habituation Regimens For Mitigating Optokinetic Side-Effects, David A. Graeber

Retrospective Theses and Dissertations

The use of incremental and repeated exposures regimens have been put forth as effective means to mitigate visually induced motion sickness based on the Dual Process Theory (DPT) (Groves & Thompson, 1970) of neural plasticity. In essence, DPT suggests that by incrementing stimulus intensity the depression opponent process should be allowed to exert greater control over the net outcome than the sensitization opponent process, thereby minimizing side-effects. This conceptual model was tested by empirically validating the effectiveness of adaptation, incremental adaptation, habituation, and incremental habituation regimens to mitigate side-effects arising from exposure to an optokinetic drum. Forty college students from the ...
