Improved Methods And System For Watermarking Halftone Images, Phil Sherry

Theses

Watermarking is becoming increasingly important for content control and authentication. Watermarking seamlessly embeds data in media that provide additional information about that media. Unfortunately, watermarking schemes that have been developed for continuous tone images cannot be directly applied to halftone images. Many of the existing watermarking methods require characteristics that are implicit in continuous tone images, but are absent from halftone images. With this in mind, it seems reasonable to develop watermarking techniques specific to halftones that are equipped to work in the binary image domain. In this thesis, existing techniques for halftone watermarking are reviewed and improvements are developed …

A Study Of Company-Initiated Training In Us And Swedish Printing Firms Relative To Prepress, Press, And Finishing Operations, Jonas Hedman

Theses

Company-initiated training has become an increasingly important activity in printing firms because of the digital revolution in the industry which started in the mid 1980's. Previously, almost every step in prepress, press and finishing was analog, but today the workflow can be 100 percent digital until the information reaches the paper on the press. The computer is the principal part of the workflow, and it is essential for a printing firm to continuously train its workforce in the new technologies in order to develop the company's human resources, and thereby to improve the workflow and even ultimately to ensure the …

Theses

This study examines the effect of the viscidity of the corporate client-advertising agency relationship and of the expert power exercised by the agency on the level of personalization in the resultant print campaign. A phone survey of 250 advertising agencies nationwide provides statistical support to the findings. The results indicate that for those advertising agencies that perform a significant volume of work on a retainer basis, the expert power exercised by the agencies and the level of the viscidity of the relationship between the clients and the agencies are in close correlation to the level of personalization employed by the …

Preserving Conformance For Gcra Regulated Flows, Deryck Hong

Theses

Traffic policing/shaping has been employed at the edge of networks to ensure proper provisioning of network resources and Quality of Service (QoS) guarantees. As shown in this thesis, however, network flows that have been regulated at the network edge based on traffic descriptors, e.g., GCRA, may still become non-conforming in the network core, depending on the packet scheduling algorithm used. Two supplemental schemes to scheduling algorithms are proposed and analyzed in this thesis to ensure conformance for GCRA regulated flows. The first scheme is to add an additional traffic regulator to shape the traffic more aggressively than required constraints before …

Design Of Asphalt Concrete Mixtures For Pavement Maintenance And Rehabilitation, Mubarak Bakheet Gaith Al-Falahi

Theses

The main objective of the thesis is to develop a knowledge base for the design of asphalt concrete mixtures suiting various types and causes of pavement distress and to develop supporting guidelines for the selection of aggregate types, gradation and binder contents for desirable mixture properties.

To achieve this objective, a two-level model was developed. The upper-level is a Factorial Experimental Design Model (FEDM) for the pavement condition evaluation. It can be used as a prediction tool to estimate the Pavement Condition Index (PCI), and determine the percentages of the types of distresses (Load, Environmental, Others). The upper-level model was …

Maximizing The Capability Of Wireless Sensor Networks, Cory Cress

Theses

Wireless micro-sensors introduce a new frontier in sensing devices and data acquisition capabilities. These sensors, capable of sensing, processing data, and short-range communication, can be spread over regions to form ad hoc wireless sensor networks (WSN) so as to deliver aggregate information from geographically diverse areas. This aggregate data gathering and processing induces a synergistic effect and enables a sensor network to complete sensing tasks that may never be feasible using a single, perhaps powerful, sensor. This new paradigm in sensing devices is not without many fundamental challenges, one being a constrained energy resource, which first need to be solved …

Aerodynamic Force And Moment Balance Design, Fabrication, And Testing For Use In Low Reynolds Flow Applications, Corey Abe

Theses

The aerodynamic performance of airfoils operating at Reynolds numbers below 105 has been of interest due to its variety of applications in areas such as unmanned remotely piloted vehicles, small-scale machinery, and more recently, Micro Air Vehicles (MAV's). Design and testing of airfoils to meet these applications is challenging due to the lack of experimental data in low Reynolds flow, compared to airfoils tested at higher Reynolds numbers. Two mechanical balance devices are designed and evaluated to provide a quick and simple method to test small airfoil aerodynamic loads. Each device measures two degrees of freedom; a force balance measures …

Within both the sculptural work and the written work I am exploring the fragility and vulnerability of being human. The reality of impermanence …

3-D Image Segmentation And Rendering, Hui Wang

Theses

Finding methods for detecting objects in computer tomography images has been an active area of research in the medical and industrial imaging communities. While the raw image can be readily displayed as 2-D slices, 3-D analysis and visualization require explicitly defined object boundaries when creating 3-D models. A basic task in 3-D image processing is the segmentation of an image that classifies voxels/pixels into objects or groups. It is very computation intensive for processing because of the huge volume of data. The objective of this research is to find an efficient way to identify, isolate and enumerate 3-D objects in …

However, governmental and educational sites …

Parametric Modeling Of Tooling: Workpiece Interaction With Engineered Abrasives, Hitesh Kataria

Theses

Abrasive processes are some of the most important operations employed in manufacturing to remove unwanted material and introduce desired geometry and surface finish. However, some of the difficulties encountered when trying to model abrasive process are related to a multi-point of contact tooling composed of extremely hard and brittle particles which geometry, shape and distribution are unknown. With the introduction of engineered abrasives to the market over the past few years, the opportunity to drastically improve the quality and consistency of abrasive machining now exists. One of the main benefits of engineered abrasives is the ability to control the abrasive …

In industry, simulation is one of the most widely used probabilistic modeling tools for modeling highly complex systems. Major sources of complexity include the inputs that drive the logic of the model. Effective simulation input modeling requires the use of accurate and efficient input modeling procedures. This research focuses on nonstationary arrival processes. The fundamental stochastic model on which this study is conducted is the nonhomogeneous Poisson process (NHPP) which has successfully been used to characterize arrival processes where the arrival rate changes over time. Although a number of methods exist for modeling the rate and mean value functions that …

Neutron Radiography Study Of Water Transport In An Operating Fuel Cell: Effects Of Diffusion Media And Cathode Channel Properties, Jon Owejan

Theses

In a polymer electrolyte membrane fuel cell, effective water management is required for optimal cell performance. While membrane hydration is needed for effective proton conduction, an excess of water, particularly on the cathode side, hinders transport of oxygen to the catalyst sites and lowers cell voltage. This study utilized neutron radiography to reveal the presence of liquid water while operating the PEMFC. These insitu experiments investigated both rectangular and triangular flow field geometries, various flow field surface energies, and several gas diffusion media samples. Correlations were drawn between accumulated water mass and performance data collected during the imaging process. The …

Twixt, Karen Schlesinger

Theses

This thesis discusses photographs exhibited at the School of Photographic Arts and Sciences Gallery at Rochester Institute of Technology from April 28 - May 10, 2003. In these photographs of desecrated landscapes at liminal times of day, the eerie light and vibrant colors of dusk and dawn enable me to create views of my personal world, a foreign and perilous place for some audiences, an intoxicating and disquieting environment for others. As the light gives way to darkness, the deepening shadows of the vegetation come alive as monstrous figures. Fears lurk in the darkness and become threatening creatures of the …

Identification And Prediction Of Nonlinear Dynamics, Andrew Dick

Theses

Chaos theory and associated analyses are being applied to a growing number of disciplines. Studies of biological and ecological systems have shown the widest application of chaotic analyses thus far. When studying these systems, it is often only possible to measure a subset of the system's many variables. To effectively perform a number of the analyses required to study a chaotic system, it is necessary to identify a complete strange attractor for the system. Consequently, it is necessary to reconstruct the system's strange attractor from the available data. Many different methods exist for reconstructing strange attractors, but the effectiveness of …

Seeing, Sensing, And Selection: Modeling Visual Perception In Complex Environments, Roxanne Canosa

Theses

The purpose of this thesis is to investigate human visual perception at the level of eye movements by describing the interaction between vision and action during natural, everyday tasks in a real-world environment. The results of the investigation provide motivation for the development of a biologically-based model of selective visual perception that relies on the relative perceptual conspicuity of certain regions within the field of view. Several experiments were designed and conducted that form the basis for the model. The experiments provide evidence that the visual system is not passive, nor is it general-purpose, but rather it is active and …

A Manufacturing Execution System Using Siemens' Pc Based Automation Technology, Prakash Gandhi

The focus of any manufacturing operation is to establish better yields, reduced cycle times, increase quality, and handle dynamic demand/resource fluctuations. Over the past few years many manufacturing companies have implemented Enterprise Resource Planning (ERP) systems and they have proved themselves to be successful in achieving these goals. However, real-time data is required in order to portray an accurate account of the day-to-day and/or hourly product manufacturing operations. Retrieval of this real-lime data is a challenging task. A Manufacturing Execution System (MES) is a real-time information system that improves the performance of the shop floor operations by linking business planning, …

Effects Of Operator Training Method On Knowledge Retention On A Common Cnc Machine Interface, Phillip Rogerson

Theses

The continued growth of computer numerically controlled (CNC) machine tool use in industry combined with increased competition in the global market requires workers to quickly attain requisite skills and raise productivity levels to meet production demands. Retention of knowledge is a key factor in an operator's ability to transfer training into actual machine operation in a production setting. This study examines the difference in short term retention of knowledge necessary to perform basic interface operations in operators trained using a conventional training method compared to those trained using a train-to-criteria method.

A Simulation Study Of Dispatching Rules And Rework Strategies In Semiconductor Manufacturing, Gregory Laubisch

Theses

The semiconductor industry is fast paced and on the cutting edge of technology, resulting in very short life spans of semiconductor products. In order to stay competitive, manufacturers must be able to quickly adapt to produce new products, and they must achieve a high level of productivity. Two major operational components of semiconductor fabrication plants (fabs) that effect productivity are dispatching rules and rework strategies. Although prior research has been conducted independently on these two issues, the hypothesis is that the interrelationship between the dispatching rules and rework strategies has a significant effect on the productivity of the fab. Moreover, …

Kinetic And Analytical Studies On Catalytic And Noncatalytic Oxidative Degradation Of Some Hazardous Organic Dyes Using Hydrogen Peroxide, Salem Hmoud Salem Al-Ameri

Theses

Dyes have become a very important part to countless modem applications. As a result of this huge consumption of dyes in manufacturing processes, huge amounts of wastewater contaminated with dyes are released into different natural dumps like rivers and seas. These dyes contaminated wastes have dangerous impacts on the environment and toxic affects. Two problems are facing scientists concerned about this environmental task. First, dyes vary in their chemical and physical natures and different waste treatments are needed which sometime are not available. Second, getting rid of these pollutants from its sources is costly, that many manufactures can not afford. …
