Proposal Of Hybrid Damping Package Design, Qi Zhang, Katsuhiko Saito, Katsushige Nagaoka

Journal of Applied Packaging Research

To protect products from shock and vibration during transport, Cushioning Packaging Design is implemented. The cushioning performance and anti-vibration performance of a package is tested by a drop test and a vibration test. The effectiveness of the cushioning during a drop test is predictable because the cushioning material`s thickness and bearing area are determined by the cushion curves which are plotted based on the results of the tests. However, an effective package-design method which can predict the package vibration of all the static stresses that are suitable for cushioning package design has not been established yet.thus, it remains ...

Designing And Building An Automatic Chamfer Grinder, William Johnson

Honors College Capstone Experience/Thesis Projects

Modern day manufacturing is a demanding environment with a constant need for process improvement. As automation becomes more advanced, there are fewer jobs that must be completed by a human. In the case of Stupp Bridge Company, a local manufacturer of steel bridge girders, their workforce is highly skilled, so replacing mundane tasks with automation allow the skilled workers to focus on the difficult jobs. One such task is grinding a chamfer onto every leading edge of each girder flange, eight edges in total, ranging from 20 to 200 feet long. The purpose of this project was to design an ...

Optimization Of A High-Speed X-Ray Imaging System For Studying Sprays, Lane E. Schultz, Mikhail N. Slipchenko, Terrence R. Meyer, Wilbert C. Slowman

The Summer Undergraduate Research Fellowship (SURF) Symposium

Spray-based liquid atomization and liquid mixing is critical for development of efficient combustors and drug delivery systems as well as multiple coating-related applications. While optical methods allow characterization of low density regions of sprays, the scattering of optical photons hinders the characterization of a dense core. Unlike optical photons, higher-energy X-ray photons have the capability to penetrate and image the core structure of sprays. Here we characterized temporal and spatial resolution of an X-Ray imaging system based on a commercially available tube source with an anode size of 0.6 mm. For high-speed imaging, a phosphor screen in combination with ...

Predicting The Effect Of Gaps Between Pallet Deckboards On The Compression Strength Of Corrugated Boxes, Matthew Baker, Laszlo Horvath, Marshall S. White

Journal of Applied Packaging Research

The majority of corrugated boxes are transported and stored on pallets where the reduced support area due to deckboard gaps has an adverse effect on the strength of the corrugated boxes Therefore, an adjustment factor is used to adjust the box compression strength to account for the lack of support, but these factors were developed for a limited range of deckboard gaps, box sizes, and box orientations. In addition, there is no predictive model that can estimate the reduction in compression strength based on the size of the box and the size of the gap. The main objective of this ...

Ir-Based Estimation Of Velocities Above Flames Spreading Over Different Fuels, Lulu Sun, Xiangyang Zhou, David R. Weise, Shankar Mahalingam

Lulu Sun

Wildfire spread in living vegetation such as chaparral in California and eucalyptus forests in Australia often causes significant damage to infrastructure and ecosystems. A physically based empirical model to predict fire spread rate is used in the United States to assist in a variety of fire management operations. The spread model does not adequately describe the chemical processes of combustion in live fuels.

Prior to describing and modeling the chemical processes of combustion in wildland fuels using computational fluid dynamics, we are investigating a technique to non-intrusively measure flame gas velocities using thermal imagery. By tracing "hot" pixels through successive ...

Lifelong Housing Design: User Feedback Evaluation Of Smart Objects And Accessible Houses For Healthy Ageing, Matteo Zallio, Niccolò Casiddu

Conference Papers

According to the latest research by the European Community and ISTAT (Italian National Institute of Statistics) surveys, Europe has the highest average age for its population. According to those data, in the near future, it could be necessary to move from a welfare model based on the centralization of care systems, to a system based on the distribution of certain healthcare facilities [1]. This means that the ageing population is ever increasing, thanks to better lifestyles, innovative medical care and wider access to different services. This work seeks to observe and analyse key implications of architectural and interior design features ...

Investigation Of Fate And Migration Of Hexavalent Chromium At The Mouat Industries Site, Columbus, Montana, Harwood Jeremy

Graduate Theses & Non-Theses

Human impacts to water resources occur in a variety of instances and are often associated with, but not limited to, nor always a result of, industrial processes. Manufacturing of Cr compounds for use as a corrosion inhibitor require the transformation of Cr into a toxic state, requiring extreme safety and caution during processing and handling.

Historical processing of chromite ore at the Mouat Industries site led to Cr-contaminated groundwater within the city limits of Columbus, MT. After the site was listed on the Environmental Protection Agency’s National Priority List in 1986, soil remediation was conducted at the site in ...

Numerical Simulation Of Live Chaparral Fire Behavior Using Firetec, Lulu Sun, Xiangyang Zhou, Shankar Mahalingam, Jesse Canfield, Rodman Linn

Lulu Sun

Fire spread through chaparral fuels is a significant feature of wildland fire in southern California. In order to study the detailed physical processes involved during fire spread, FIRETEC, a coupled atmosphere/wildfire behavior model was refined to examine chaparral fire behavior. FIRETEC combines a sophisticated fine-scale model to simulate a three- dimensional wildfire, moving over a terrain-following finite volume grid, with the motions of the local atmosphere. It accounts for the microscopic details of a fire with macroscopic resolution by dividing quantities into mean and fluctuating parts and the resulting transport equations are solved by using a finite difference method ...

Fire Behavior Of Some Southern California Live Chaparral Fuels, Lulu Sun, Xiangyang Zhou, Shankar Mahalingam, David R. Weise

Lulu Sun

Wildfire spread in living vegetation, such as chaparral in southern California, often causes significant damage to infrastructure and ecosystems. In order to study wildfire spread in living vegetation, four of the most common chaparral in southern California, chamise, manzanita, scrub oak and ceanothus, were burned and compared. The observed fire behavior included mass loss rate, flame height, temperature structure and velocity field above the burning fuel bed. It was observed that flame height increases mainly with heat release rate. By using successive images of the temperature field, a recently developed thermal particle image velocity (TPIV) algorithm was applied to estimate ...
