Solution Strategies For A Supply Chain Deterministic Model, Ming Hong

Theses

To most firms, intelligent supply chain decisions are essential to achieve competitiveness in an environment characterized with increasing globalization and relentless changes. As the supply chain concept largely evolved from traditional logistics management, practitioners and researchers have historically focused on the individual processes of a supply chain. A wide array of mathematical models have been developed to tackle such functional issues as inventory level, lead-time performance, delivery performance, customer satisfaction and so on. This research presents a model that aims to evaluate and optimize the overall performance of the supply chain. The key nodes and variables in the model are …

Quantitative Analysis Of Infrared Contrast Enhancement Algorithms, Seth Weith-Glushko

Theses

This thesis examines a quantitative analysis of infrared contrast enhancement algorithms found in literature and developed by the author. Four algorithms were studied, three of which were found in literature and one developed by the author: tail-less plateau equalization (TPE), adaptive plateau equalization (APE), the method according to Aare Mallo (MEAM), and infrared multi-scale retinex (IMSR). Engineering code was developed for each algorithm. From this engineering code, a rate of growth analysis was conducted to determine each algorithm’s computational load. From the analysis, it was found that all algorithms with the exception of IMSR have a desirable linear nature. Once …

On The Applicability Of Random Mobility Models For Swarm Robot Movements, Siddharth Sail

Theses

Random mobility models have been traditionally used to represent cellular or ad hoc movement patterns for PDA and laptop users. These models are critical for network traffic and protocol analysis. As robotics move to a paradigm where wireless network protocols are being utilized, it is unclear whether the same mobility models are applicable for analyzing these wireless network protocols. This thesis examines the similarity and differences between the traditional random mobility models and the mobility patterns exhibited by a team of randomly moving robots. Though the movements are driven by the same random functions, the robots need to detect and …

Generalized Construction Of Trend Resistent 2-Level Split-Plot Designs, Guillermo Lopez

Theses

Common experimental practices suggest randomizing the order in which runs are performed. However, there may be situations in which randomization might not produce the most desirable order, especially in the presence of known trends. There has been research done on systematically designing experiments to be robust against trends. However, few studies address the additional dimensions that arise in nested designs such as split-plot designs. Split-plot designs have been used for many years in agricultural applications and are sometimes preferred where there are hard-to-change factors in industrial settings. There currently is no established methodology to produce split-plot designs that are robust …

A Reverse Engineering Process For Mechanical Engineering Systems, Frank Tamarez-Gomez

Theses

This thesis presents a literature review of current reverse engineering technologies and processes, with an emphasis on tools commonly used in Software Reverse Engineering (SRE). Using the foundation of the literature review, the thesis will then propose a standard process, referred to as "A Reverse Engineering Process for Mechanical Engineering Systems (REPMES)." The REPMES tool is intended to enable engineers to understand how current products work. Additionally, REPMES may allow engineering design teams to more effectively revise their product designs through competitive benchmarking. The REPMES is illustrated through application to case studies of a consumer flashlight and an automotive torque …

Multi-Degree Of Freedom Telemanipulation In An Unstructured Environment, Diego Ramirez

Theses

Two approaches to 6-degrees-of-freedom telemanipulation that will accommodate different needs and skills of potential users with congenital amputation, arthrogryposis, muscular dystrophy and cerebral palsy were developed. One method uses scalable movements (i.e. position and orientation), and the second employs isometric forces and torques without movement. The scalable position approach employs a 6-degress-of-freedom electromechanical stylus whose joint orientations are used by the controlling computer to determine the position and orientation of the robot's end effector via inverse kinematics or by one-to-one matching of the stylus joint angles with those of the manipulator. The isometric method uses the measured forces and torques …

Development Of Enzymatic Biofuel Cell Based On Carbon Nanotube Electrodes On Porous Silicon, Fan Yang

Theses

The work presented in this thesis has focused on designing and characterizing biofuel cell electrodes using porous silicon (p-Si) as the substrate or current collecting platform on which carbon nanotubes (CNTs), both single-walled carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MiWNTs), were synthesized directly, followed by enzyme catalyst immobilization on the CNTs. Laccase and glucose oxidase (GOx) were used as enzymatic biocatalysts, which were immobilized on the CNT walls and tips using an electrochemical technique. Cyclic voltammetry showed well-defined redox peaks which indicated that the enzyme (GOx and laccase) were successfully immobilized on the CNTs. The amperometric responses of the …

Burmester Curve And Numerical Motion Generation Of Grashof Mechanisms With Perimeter And Transmission Angle Optimization In Mathcad, Peter J. Martin

Theses

An infinite number of planar four-bar mechanism solutions exist for a series of prescribed rigid-body positions. Given a set of Burmester curves or numerically-generated fixed and moving pivot curves, sorting through the limitless number of possible mechanism solutions to find one that ensures full link rotatibility, satisfies compactness criteria and produces feasible transmission angles can be a daunting task. In this work, two algorithms are developed and presented by which the user can select optimum planar four-bar motion generators (optimum with respect to Grashof criteria, mechanism perimeter criteria and transmission angle criteria) from a set of all mechanism solutions produced …

Implementation Of Stereo Correspondence Algorithms For Multi-Baseline Vision System, Navaneetha Shivram

Theses

The purpose of this study is to determine the impact of varying camera baselines on correspondence and depth estimation. As the baseline increases the resolution of depth increases but finding correspondences is very tedious. On the other hand when cameras are placed close to each other and thereby reducing the baseline distance points in the images are easily matched however depth resolution deteriorates. This problem is solved by using a multi-camera system is used in which the cameras are spaced close to each other along a straight line. Calculating the correspondence along successive camera pairs is relatively easy. These respondences …

Determining Continual Improvement Process Methods Within Quality Management Systems, Diane M. Bové

Theses

Institutionalized standards require organizations to actively define and implement quality management systems, which includes active participation in continual improvement efforts. Interpretations and practices vary on implementation methodology.

Traditional views of quality do not integrate the technical disciplines into a defined science which would support a standardized approach for continual improvement implementation.

In order to optimize improvement efforts, a conceptual hypothesis is proposed to integrate quality through combining and collaborating implementation efforts of engineering, control, assurance, improvement and costs. The purpose of this thesis is to establish a roadmap to assist in choosing effective quality improvement methodologies and toolsets that assist …

Channel-Predictive Link Layer Arq Protocols In Wireless Networks, Huseyin Dogukan Cavdar

Theses

Communication performance over a wireless channel should be considered according to two main parameters: energy and throughput. The reliable data transfer is a key to these goals. The reliable node-to-node data transfer is performed by link layer protocols. One prominent approach is Automatic Repeat Request (ARQ) protocol. The traditional ARQ protocols attempt to recover the erroneously transmitted frames by retransmitting those frames, regardless of the channel state. Since this channel state unaware behaviour may cause unnecessary retransmissions, traditional ARQ protocols are expected to be energy inefficient. Some ideas have been proposed such as stochastic learning automaton based ARQ, and channel …

Jet Assisted Fluidization Of Nanoparticle Agglomerates, Ayokunle O. Omosebi

Theses

Fluidization serves as a primary operation used to disperse, handle and process nanoparticles, but due to the complications involved with achieving homogenous fluidization of the agglomerates of nanoparticles, several methods have been developed to assist their conventional mode of fluidization.

In this work, the conventional mode of fluidization was coupled with secondary gas flow emerging from a micro jet nozzle. The effect of the jet on the fluidization behavior of various APF and ABF nanopowders was studied and compared with the pure conventional fluidization mode. Generally, experiments were conducted to find the optimal operation of the jet by varying parameters …

Inverse Dynamic Modeling For Characterization Of Spasticity, Katharine Markel Swift

Theses

Spasticity affects subjects with cerebral palsy, stroke, multiple sclerosis, and traumatic brain injury. The need to develop a deeper understanding of spasticity is driven by the existing limited understanding and the lack of satisfactory interventions for this disabling phenomenon.

An inverse model is implemented to describe the motion in the pendulum knee drop test. Inverse kinematic modeling is implemented to investigate the pathophysiology of spasticity.

Using the equilibrium point hypothesis as a conceptual framework to explain disabled and non-disabled neuromuscular control, it has been demonstrated that the equilibrium point of the passive knee is dynamic and exhibits a pseudo-exponential trajectory …

Analyzing Metallic Gloss Using A Micro-Goniophotometer, Saara Suni

Theses

Metallic inks are in widespread use in the graphic arts industry, but there currentiy is no way to "put a number" on metallic gloss. Process-control methods, such as densitometry, which analyzes how light is absorbed into the ink layer, are not usable for metallics, since hardly any light gets absorbed. In addition, it is very difficult to see visual differences when the ink film thickness crosses a certain threshold.

Dr. Jonathan Arney at the Chester F. Carlson Center for Imaging Science at Rochester Institute of Technology (RTT) has been using a micro-goniophotometer for analyzing paper gloss on a microstructure level, …

Nonlinear Vibration Of A Cantilever Beam, Iván Delgado-Velázquez

Theses

The vibration of a highly flexible cantilever beam is investigated. The order three equations of motion, developed by Crespo da Silva and Glyn (1978), for the nonlinear flexural-flexural-torsional vibration of inextensional beams, are used to investigate the time response of the beam subjected to harmonic excitation at the base. The equation for the planar flexural vibration of the beam is solved using the finite element method. The finite element model developed in this work employs Galerkin's weighted residuals method, combined with the Newmark technique, and an iterative process. This finite element model is implemented in the program NLB1, which is …

The Performance Of Group Diffie-Hellman Paradigms: A Software Framework And Analysis, Kieran S. Hagzan

Theses

A mobile computing environment typically involves groups of small, low-power devices interconnected through a mobile and dynamic network. Attempts to secure communication over these “ad-hoc” networks must be scalable to conserve the minimal resources of mobile devices as network sizes grow. In this project, the scalability of differing Group Diffie-Hellman security key generation implementations is examined. In theory, the implementation utilizing a data structure with the lowest theoretical run-time complexity for building the Diffie-Hellman group should prove the most scalable experimentally. A common modular framework was implemented to support generic Group Diffie-Hellman key agreement implementations abstracted from the underlying data …

Audio Watermarking Techniques Using Singular Value Decomposition, Joseph Kardamis

Theses

In an increasingly digital world, proving ownership of files is more and more difficult. For audio files, many schemes have been put into place to attempt to protect the rights of the digital content owners. In general, these techniques fall under the classification of Digital Rights Management (DRM). Audio watermarking is one of the less invasive schemes which embeds security into the data itself instead of in an outside layer meant to encapsulate and protect the data. There are many domains in which an audio watermark can be applied. The simplest is that of the time domain; often, however, other …

Performance Evaluation Of Extended Sparse Linearization In Gf(2) And Gf(28), Tigin Kaptanoglu

Theses

XSL (eXtended Sparse Linearization) is a recent algebraic attack aimed at the Advanced Encryption Standard. In order to shed some light into the behavior of the algorithm, which is largely unknown, we have studied XSL on equation systems with variables interpreted either as bits or bytes. The algorithm solves byte-systems much faster than it does bit-systems, which promts us to suggest that if a more compact representation of equation systems can be found, such as one where the variables are 8-byte blocks, or even a more generalized form of 8n-byte blocks, it may be possible to increase the speed of …

On-Chip Digital Decoupling Capacitance Methodology, Eric Scott Bohannon

Theses

Signal integrity has become a major problem in digital IC design. One cause of this problem is device scaling which results in a sharp reduction of supply voltage, creating stringent noise margin requirements to ensure functionality. Reductions in feature size also result in increased clock speeds leading to many different high frequency noise producing components. As on-chip area increases to allow for more computational capability, so does the amount of digital logic to be placed, magnifying the effects of noisy interconnect structures.

Supply noise, modeled as AV = Ldi/dt , is caused by rapid current spikes during a rise or …

Ieee Compliant Double-Precision Fpu And 64-Bit Alu With Variable Latency Integer Divider, Ryan D. Williams

Theses

Together the arithmetic logic unit (ALU) and floating-point unit (FPU) perform all of the mathematical and logic operations of computer processors. Because they are used so prominently, they fall in the critical path of the central processing unit - often becoming the bottleneck, or limiting factor for performance. As such, the design of a high-speed ALU and FPU is vital to creating a processor capable of performing up to the demanding standards of today's computer users.

In this paper, both a 64-bit ALU and a 64-bit FPU are designed based on the reduced instruction set computer architecture. The ALU performs …
