Virtual Blasting System For Removal Of Coating And/Or Rust From A Virtual Surface, Michael Bolick, Chris Lampe, Jason Ebensberger, Jeremiah Treloar, Rick Klein, Eric Conrad Peterson, Chad Jason Zalkin

Patents (University of Northern Iowa)

A computer simulation and virtual reality system simulates the use of a blasting nozzle to remove one or more coatings and/or rust from a virtual surface. The user operates an electronic controller in the form of a blasting nozzle that outputs a signal indicating whether the blasting nozzle controller is in an "on" position or in an "off" position. The system also has a motion tracking system that tracks the position and orientation of the blasting nozzle controller with respect to the virtual surface defined on the display screen. Simulation software in a computer generates virtual blast pattern data ...


The Green And Ampt Infiltration Model Accounting For Air Compression And Air Counterflow In The Shallow Water Table Environment: Laboratory Experiments, Yuliya Lukyanets 2010 University of South Florida

The Green And Ampt Infiltration Model Accounting For Air Compression And Air Counterflow In The Shallow Water Table Environment: Laboratory Experiments, Yuliya Lukyanets

Graduate Theses and Dissertations

Water infiltration into the unsaturated zone especially in a shallow water table environment is affected by air compression ahead of the wetting front and air counterflow. Neglecting air compression in infiltration modeling can overestimate infiltration and infiltration rates, whereas not accounting for air counterflow can underestimate infiltration and infiltration rates due to unrealistic buildup of air pressure resistance ahead of the wetting front. A method, derived on the basis of the Green and Ampt (1911) infiltration model, is introduced to simulate air compression and air counterflow during infiltration into a shallow water table. The method retains the simplicity of the ...


Individual Muscle Contributions To The Axial Knee Joint Contact Force During Normal Walking, Kotaro Sasaki, Richard R. Neptune 2010 Boise State University

Individual Muscle Contributions To The Axial Knee Joint Contact Force During Normal Walking, Kotaro Sasaki, Richard R. Neptune

Mechanical and Biomedical Engineering Faculty Publications and Presentations

Muscles are significant contributors to the high joint forces developed in the knee during human walking. Not only do muscles contribute to the knee joint forces by acting to compress the joint, but they also develop joint forces indirectly through their contributions to the ground reaction forces via dynamic coupling. Thus, muscles can have significant contributions to forces at joints they do not span. However, few studies have investigated how the major lower-limb muscles contribute to the knee joint contact forces during walking. The goal of this study was to use a muscle-actuated forward dynamics simulation of walking to identify ...


Concurrent Muscoskeletal Dynamics And Finite Element Analysis Predicts Altered Gait Patterns To Reduce Foot Tissue Loading, Jason P. Halloran, Marko Ackermann, Antonie J. van den Bogert 2010 Cleveland Clinic

Concurrent Muscoskeletal Dynamics And Finite Element Analysis Predicts Altered Gait Patterns To Reduce Foot Tissue Loading, Jason P. Halloran, Marko Ackermann, Antonie J. Van Den Bogert

Mechanical Engineering Faculty Publications

Current computational methods for simulating locomotion have primarily used muscle-driven multibody dynamics, in which neuromuscular control is optimized. Such simulations generally represent joints and soft tissue as simple kinematic or elastic elements for computational efficiency. These assumptions limit application in studies such as ligament injury or osteoarthritis, where local tissue loading must be predicted. Conversely, tissue can be simulated using the finite element method with assumed or measured boundary conditions, but this does not represent the effects of whole body dynamics and neuromuscular control. Coupling the two domains would overcome these limitations and allow prediction of movement strategies guided by ...


High-Pressure And High-Temperature Density Measurements Of N-Pentane, N-Octane, 2,2,4-Trimethylpentane, Cyclooctane, N-Decane, And Toluene, Yue Wu 2010 Virginia Commonwealth University

High-Pressure And High-Temperature Density Measurements Of N-Pentane, N-Octane, 2,2,4-Trimethylpentane, Cyclooctane, N-Decane, And Toluene, Yue Wu

Theses and Dissertations

Information on the density of hydrocarbons at high pressures and temperatures is of great importance in many fields, such as the study of ultra-deep reservoirs up to ~240 MPa and 250°C. However, density data at such high pressures and temperatures are often not available in the literature. In this study, experimental densities are reported for n-pentane, n-octane, 2,2,4-trimethylpentane, cyclooctane, n-decane, and toluene to ~280 MPa and ~250°C. These experimental densities are in good agreement with available literature data, although the literature data for many of these fluids do not extend to the pressures and temperatures utilized ...

A Framework Based On Gaussian Mixture Models And Kalman Filters For The Segmentation And Tracking Of Anomalous Events In Shipboard Video, Ben Wenger

Theses and Dissertations

Anomalous indications in monitoring equipment on board U.S. Navy vessels must be handled in a timely manner to prevent catastrophic system failure. The development of sensor data analysis techniques to assist a ship's crew in monitoring machinery and summon required ship-to-shore assistance is of considerable benefit to the Navy. In addition, the Navy has a large interest in the development of distance support technology in its ongoing efforts to reduce manning on ships. In this thesis, algorithms have been developed for the detection of anomalous events that can be identified from the analysis of monochromatic stationary ship surveillance ...

Cavity Resonant Mode In A Metal Film Perforated With Two-Dimensional Triangular Lattice Hole Arrays, Wan Kuang, Alex English, William B. Knowlton, Jeunghoon Lee, William L. Hughes, Bernard Yurke

Electrical and Computer Engineering Faculty Publications and Presentations

The transmission property of metallic films with two-dimensional hole arrays is studied experimentally and numerically. For a triangular lattice subwavelength hole array in a 150 nm thick Ag film, both cavity resonance and planar surface modes are identified as the sources of enhanced optical transmissions. Semi-analytical models are developed for calculating the dispersion relation of the cavity resonant mode. They agree well with the experimental results and full-wave numerical calculations. Strong interaction between the cavity resonant mode and surface modes is also observed.


Tilted Guides With Friction In Web Conveyance Systems, M. R. Brake, Jonathan A. Wickert 2010 Sandia National Laboratories

Tilted Guides With Friction In Web Conveyance Systems, M. R. Brake, Jonathan A. Wickert

Mechanical Engineering Publications

One challenge in designing web conveyance systems is controlling the displacement and vibration of the webs by guides without introducing instabilities or higher frequency disturbances from flange impacts. A solution to this problem is to use an actively or passively tilted guide or roller to steer the web. In this paper, a model of tilted guides with friction is developed, and it is shown that tilted guides produce a change in the web’s displacement, slope, bending moment, and shear force. When the web is conceptually unwrapped from its path, the normal force between the web and a tilted guide ...


Structural And Mechanical Properties Of Nanostructured Tio2 Thin Films Deposited By Rf Sputtering, 2010 Selected Works

Structural And Mechanical Properties Of Nanostructured Tio2 Thin Films Deposited By Rf Sputtering

A.S. Md Abdul Haseeb

This study mainly aims to evaluate the effects of substrate temperatures on the mechanical properties of TiO2 thin films deposited on glass substrates by radio-frequency (RF) magnetron sputtering. All titania films possess anatase structure having a nodular morphology. AES results reveal that Si and Na ions from glass diffuse into TiO2 films at higher substrate temperatures. Micro-scratch and wear tests were conducted to evaluate their mechanical and tribological properties. The adhesion critical loads of TiO2 films deposited at room temperature, 200 and 300°C are found to be 1.51, 1.54 and 1.08N, respectively. Scratch hardness also increases ...
