On The Strain-Rate Sensitivity Of Columnar Ice, M. E. Manley, E. M. Schulson
On The Strain-Rate Sensitivity Of Columnar Ice, M. E. Manley, E. M. Schulson
Dartmouth Scholarship
A power law relation between stress and strain rate of the form σ ∝ ε̇1/n was used to describe the response to strain rate of S1 ice loaded across the columns at -10°C. The rate exponent, n, decreased with increasing strain from about 4.6 at an observed peak on the load displacement curve to approximately 2.6 at a shortening of 2%. Analysis of these results and of the results of other authors on different forms of ice deformed at the same temperature suggests that the power law exponent, n, is proportional to Fc/Fg. The parameter Fc/Fg is the far-field basal …

Markovian Decision Control For Traffic Signal Systems, Xiao-Hua Yu, Allen R. Stubberud
Electrical Engineering
Setting signals at intersections to minimize the queue length and vehicle delay time is a key goal in traffic management. In this paper, a new control strategy for a signalized traffic intersection is developed by applying Markovian decision control theory. Statistical analysis of simulation results with different arrival rates indicate the excellent potential of this approach.
Optimal Block Encoding And Optimal Entropy For Lossless Image Compression, Larry Ray Dennis
Optimal Block Encoding And Optimal Entropy For Lossless Image Compression, Larry Ray Dennis
Dissertations and Theses
In this thesis, a novel approach is designed using a quad-tree stack structure to encode the image to determine the optimal block size at the optimal and effective entropy in the lossless image compression method. Proof is given through encoding of the predictor and randomly constructed planes. There is a high degree of relationship between the placement of bits in the planes. Clearly results shows that use of the optimal entropy and encoding block sizes will increase the compression ratio using the lossless method. The cost of using the block size methods to encoding and entropy is discussed and proven. …

Determination Of A Flexibility Range For Cellular Manufacturing Systems Under Product Mix Variations, Hamid Seifoddini, Manocher Djassemi
Determination Of A Flexibility Range For Cellular Manufacturing Systems Under Product Mix Variations, Hamid Seifoddini, Manocher Djassemi
Industrial Technology and Packaging
One of the underlying assumptions in cellular manufacturing is that product mix is relatively stable over time. In this paper, a procedure for the sensitivity analysis of the performance of a cellular manufacturing system with respect to changes in the product mix is presented and a flexibility range representing the capability of the system in dealing with these changes is determined using simulation modelling. The simulation results in this study show that as the changes in the product mix increase the superiority of the performance of the cellular manufacturing system to the corresponding job shop system diminishes.

Formation Of A Metastable Bcc Solid Solution And Decomposition To A C15 Laves Phase In Melt-Spun Crnb10Ti10, Katherine C. Chen, P. G. Kotula, F. Chu, Dan J. Thoma
Materials Engineering
A metastable, disordered bcc phase has been formed from the melt in a Cr-rich alloy of the Nb-Cr-Ti system, where large volume fractions of the Laves phase would develop under equilibrium solidification conditions. X-ray diffraction (XRD) studies and lattice constant determinations confirm that the melt-spun ribbons contain a bcc phase beyond its terminal solid solution limits. Solidification pathways are proposed based upon metastable and equilibrium phase diagrams. Microstructures have been studied using optical microscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Cross-sectional TEM reveals tiny, dispersed Laves phase precipitates within the metastable bcc grains near the chill (wheel) …

The Development Of Electromechanical Batteries For Power System Support And For Short-Term Standby Power, Michael Peter O'Leary
Masters
The slow move from a fossil-fuel powered society to a renewable-energy powered society is creating and will continue to create a demand for good energy storage techniques. The electromechanical battery (EMB), comprising a flywheel energy storage system with electrical input and output, is one of the many candidate technologies. Two different EMB types are evaluated in this present project. The first is a ring (or annular) flywheel to be constructed using fibre composite materials and to rotate at high speed in a vacuum. Energy is to be imported and exported electromagnetically based on linear electrical machine principles. Confinement of the …

Coincidences Are Not Accidental: A Theorem, Vladik Kreinovich
Coincidences Are Not Accidental: A Theorem, Vladik Kreinovich
Departmental Technical Reports (CS)
In this paper, we formalize and prove the statement that coincidences cannot be accidental, a statement that underlies many useful heuristics in mathematics and physics.
Our proof uses a version of Kolmogorov complexity, a technique originally developed to describe randomness and "accidentalness".
Why Kolmogorov Complexity In Physical Equations, Vladik Kreinovich, Luc Longpre
Why Kolmogorov Complexity In Physical Equations, Vladik Kreinovich, Luc Longpre
Departmental Technical Reports (CS)
Several researchers, including M. Gell-Mann, argue that the notion of Kolmogorov complexity, developed in the algorithmic information theory, is useful in physics (i.e., in the description of the physical world). Their arguments are rather convincing, but there seems to be a gap between traditional physical equations and Kolmogorov complexity: namely, it is not clear how the standard equations of physics can lead to algorithmic notions underlying Kolmogorov complexity. In this paper, this "gap" is bridged: we explain how Kolmogorov complexity naturally appear in physical equation.
Joint Map Registration And High Resolution Image Estimation Using A Sequence Of Undersampled Images, Russell C. Hardie, Kenneth J. Barnard, Ernest E. Armstrong
Joint Map Registration And High Resolution Image Estimation Using A Sequence Of Undersampled Images, Russell C. Hardie, Kenneth J. Barnard, Ernest E. Armstrong
Electrical and Computer Engineering Faculty Publications
n many imaging systems, the detector array is not sufficiently dense to adequately sample the scene with the desired field of view. This is particularly true for many infrared focal plane arrays. Thus, the resulting images may be severely aliased. This paper examines a technique for estimating a high-resolution image, with reduced aliasing, from a sequence of undersampled frames. Several approaches to this problem have been investigated previously. However, in this paper a maximum a posteriori (MAP) framework for jointly estimating image registration parameters and the high-resolution image is presented. Several previous approaches have relied on knowing the registration parameters …
Investigation And Demonstration Of A Rich Combustor Cold Start Device For Alcohol Fueled Engines, David Kim Irick
Investigation And Demonstration Of A Rich Combustor Cold Start Device For Alcohol Fueled Engines, David Kim Irick
Doctoral Dissertations
Alcohols (methanol and ethanol) have been identified as having the potential to improve air quality when used to replace conventional gasoline. This potential is primarily due to the different organic species that are emitted by alcohol-fueled engines. The use of "near neat" alcohols gives greater benefits than fuels containing lower levels of alcohol, but neat alcohols present a significant cold starting problem.
The primary objective of this study was to develop a rich combustor device which will extend the cold start range of alcohol fueled engines to -30°C while reducing cold start emissions. In support of this objective a software …

Spacing Of Connections In Compression Elements For Cold-Formed Steel Members (Beams), Michael L. Jones, Roger A. Laboube, Wei-Wen Yu
CCFSS Library (1939 - present)
PREFACE The spacing of connectors in compression elements of built-up flexural members was evaluated both experimentally and analytically at the University ofMissouri-Rolla (UMR) under the sponsorship of the American Iron and Steel Institute. A computational model was developed for determining the bending capacity of single-fluted sections with cover plates that do not have edge stiffeners. The results of the investigation are presented and recommendations are made for design of single-flute cross sections having cover plates without edge stiffeners. Previous research developments by Yener, at Purdue University, and Luttrell, at the University of West Virginia, were compared to the UMR experimental …

Development Of A Versatile Wide-Angle Lens Characterization Strategy For Use In The Omnister Stereo Vision System, Keith B. Johnson
Development Of A Versatile Wide-Angle Lens Characterization Strategy For Use In The Omnister Stereo Vision System, Keith B. Johnson
Masters Theses
This thesis details the development of an accurate and efficient wide-angle stereo vision system. Wide-angle or fisheye stereo is desired because it provides the capability to recover depth information for a large scene from a single stereo image pair. However, nonlinear image distortions caused by the camera optics complicate the necessary stereo processes of camera modeling and disparity analysis . The characterization and removal of these lens distortions therefore is considered vital to stereo evaluation of fisheye images. Existing wide-angle stereo systems have maintained the use of pinhole projections to model the respective camera systems . This ideal projection model …
