Screen Printing Process Design Of Experiments For Fine Line Printing Of Thick Film Ceramic Substrates, Jianbiao Pan, Gregory L. Tonkay, Alejandro Quintero Nov 1998

#### Screen Printing Process Design Of Experiments For Fine Line Printing Of Thick Film Ceramic Substrates, Jianbiao Pan, Gregory L. Tonkay, Alejandro Quintero

##### Industrial and Manufacturing Engineering

Screen printing has been the dominant method of thick film deposition because of its low cost. Many experiments in industry have been done and many models of the printing process have been developed since the 1960’s. With a growing need for denser packaging and a drive for higher pin count, screen printing has been refined to yield high resolution prints. However, fine line printing is still considered by industry to be difficult. In order to yield high resolution prints with high first pass yields and manufacturing throughput, the printing process must be controlled stringently.

This paper focuses on investigating ...

A Slip-Line Field For Ploughing During Orthogonal Cutting, Daniel J. Waldorf, Richard E. Devor, Shiv. G. Kapoor Nov 1998

#### A Slip-Line Field For Ploughing During Orthogonal Cutting, Daniel J. Waldorf, Richard E. Devor, Shiv. G. Kapoor

##### Industrial and Manufacturing Engineering

Under normal machining conditions, the cutting forces are primarily due to the bulk shearing of the workpiece material in a narrow zone called the shear zone. However, under finishing conditions, when the uncut chip thickness is of the order of the cutting edge radius, a ploughing component of the forces becomes significant as compared to the shear forces. Predicting forces under these conditions requires an estimate of ploughing. A slip-line field is developed to model the ploughing components of the cutting force. The field is based on other slip-line fields developed for a rigid wedge sliding on a half-space and ...

Fuzzy Logic Control Of A Model Airplane, Jon C. Ervin, Sema E. Alptekin Oct 1998

#### Fuzzy Logic Control Of A Model Airplane, Jon C. Ervin, Sema E. Alptekin

##### Industrial and Manufacturing Engineering

Common uses of fuzzy logic control today are found in relatively simple applications in products. These applications only scratch the surface of the potential of fuzzy logic control in complex mechatronic systems. In order to demonstrate the utility of fuzzy logic in complex device control, a fuzzy logic fly-by-wire system has been developed for a model airplane. The model airplane is a complex system of several critical inputs that require rapid processing and action in order to maintain flight stability. In addition, payload and power constraints severely limit the size, weight and processing power of the hardware to be carried ...

A Parametric Programming Technique For Efficient Cnc Machining Operations, Manocher Djassemi Oct 1998

#### A Parametric Programming Technique For Efficient Cnc Machining Operations, Manocher Djassemi

##### Industrial Technology and Packaging

In this paper the application of parametric programming to CNC machining is discussed. As one of the less frequently utilized features of CNC machines, parametric programming has the potential to increase the efficiency of CNC operations. This feature is particularly beneficial to companies with group technology manufacturing where parts with similar design or operational requirements are processed within a machine cell. Using two case studies, the capabilities of parametric programming for CNC machines are illustrated.

Communication And Uncertainty In Concurrent Engineering, Christoph. H. Loch, Christian Terwiesch Aug 1998

#### Communication And Uncertainty In Concurrent Engineering, Christoph. H. Loch, Christian Terwiesch

##### Operations, Information and Decisions Papers

We present an analytical model of concurrent engineering, where an upstream and a down-stream task are overlapped to minimize time-to-market. The gain from overlapping activities must be weighed against the delay from rework that results from proceeding in parallel based on preliminary information. Communication reduces the negative effect of rework at the expense of communication time. We derive the optimal levels of concurrency combined with communication, and we analyze how these two decisions interact in the presence of uncertainty and dependence. Uncertainty is modeled via the average rate of engineering changes, and its reduction via the change of the modification ...

#### Low Vision, Stimulus Encoding And Information Processing: A Characterization Of Performance Of Partially Sighted Users On Computer-Based Tasks, Max A. Dixon

##### FIU Electronic Theses and Dissertations

This study focuses on the characterization of partially sighted users' performance within a graphical user interface environment. Participants, ranging in visual abilities from fully sighted (FSU) with no visual impairments to partially sighted (PSU) with limited visual abilities, participated in computer-based search and select tasks. It is shown that visual search strategies employed by both PSU and FSU within a graphical user interface can be described by Steinberg's (1969) Additive Factor Model. In addition, selection strategies, measured by mouse movement times, are linearly related and highly correlated to the Index of Difficulty as explained by Fitts' Law. This is ...

Maximally Disjoint Solutions Of The Set Covering Problem, David J. Rader, Peter L. Hammer Jul 1998

#### Maximally Disjoint Solutions Of The Set Covering Problem, David J. Rader, Peter L. Hammer

##### Mathematical Sciences Technical Reports (MSTR)

This paper is concerned with finding two solutions of a set covering problem that have a minimum number of variables in common. We show that this problem is NP­ complete, even in the case where we are only interested in completely disjoint solutions. We describe three heuristic methods based on the standard greedy algorithm for set covering problems. Two of these algorithms find the solutions sequentially, while the third finds them simultaneously. A local search method for reducing the overlap of the two given solutions is then described. This method involves the solution of a reduced set covering problem. Finally ...

#### Meta-Ethnographic Development Of A Dialogue Methodology Applied To Organization Discourse, Shelley P. Gallup

##### Engineering Management & Systems Engineering Theses & Dissertations

A gap exists between theoretical stances that acknowledge the importance of dialogue as a dynamic within socially constructed structures, and "steersmanship" of those constructs--e.g., directing, intervening or transforming organizations. A "mechanism" which links theory with practice is missing, leaving practitioners with an acknowledgment of dialogue's central position, but without tools to enact this centrality in practice or research. This research constructs a conceptual model of dialogue, derived from the literature. Using this model as a base, the research seeks to generate a dialogue methodology bridging theory and practice with respect to organizational dialogue. The model, methodology, and research ...

#### Consortia As Technology Innovation Management Vehicles: Toward A Framework For Success In Venture Based Public-Private Partnerships, Ralph B. Saunders Ii

##### Engineering Management & Systems Engineering Theses & Dissertations

The purpose of this research was to explore the approach by federal/state agencies, university, and private sector consortia to develop and manage commercialization of innovation technologies. The evaluation, support, and management of technologically based consortia has traditionally been held in the private sector. There is a somewhat mature literature guiding innovation management (Utterback 1996; Rosenberg et al. 1994; Quinn 1997, 1992) in the private sector. However, there is an increasing emergence of consortia consisting of universities, industrial/private sector entities, and government agencies joining in collaborative efforts to launch technology based initiatives. These consortia are non-traditional and the applicability ...

Study Of Human Factors Variables In Battle Outcome Prediction Models, David Andrew Glovier Apr 1998

#### Study Of Human Factors Variables In Battle Outcome Prediction Models, David Andrew Glovier

##### Engineering Management & Systems Engineering Theses & Dissertations

Over time there have been many improvements in models that are used to predict the outcome of battles. Currently there is much supposition and speculation surrounding the use of human performance related factors as additional inputs to battle simulation models to improve their accuracy. However there is no conclusive scientific evidence which shows that these factors do make a significant difference. This study investigates the use of factors that may impact on the human performance directly or indirectly in battle prediction models. These factors consist of traditional human factors and external factors that may influence the human performance. The research ...

#### A Study To Analyze And Improve Mechanical And Electro-Mechanical Designs Using Design For Quality Manufacturability (Dfqm) Technique, Bhavani P. Veerapaneni

##### Theses

The competitive nature of modern manufacturing demands that an innovative approach be used to build advanced and robust designs. Shortening the product development time, which is the period from initial design to full production, is a priority to most manufacturers today. Design for Quality Manufacturability (DFQM) is a methodology to address manufacturing / assembly quality issues during product design. As a consequence DFQM helps shorten the product development time.

The DFQM methodology addresses the issue of quality manufacturability (QM) - the likely hood that defects will occur during the manufacture of a product in a standard plant. The DFQM architecture identifies a ...
