Journal of Applied Packaging Research
This research examines the effect of top-to-bottom static compression load on the bulge of RSC containers. The study compares a control regular slotted container (RSC) constructed with corrugated fiberboard to tape-reinforced designs. The bulge reduction, achieved using various tape placements and conditioning environments, were measured. Currently, no research on the effect of reinforcement tape towards reduction in the out-of-plane displacement (bulging) of the corrugated fiberboard panels has been undertaken. Samples related to four different container designs, varying by presence, quantity and the position of the reinforcement tape on the vertical panels, were tested and analyzed.

Towards A Cyber-Physical Manufacturing Cloud Through Operable Digital Twins And Virtual Production Lines, Md Rakib Shahriar
Graduate Theses and Dissertations
In last decade, the paradigm of Cyber-Physical Systems (CPS) has integrated industrial manufacturing systems with Cloud Computing technologies for Cloud Manufacturing. Up to 2015, there were many CPS-based manufacturing systems that collected real-time machining data to perform remote monitoring, prognostics and health management, and predictive maintenance. However, these CPS-integrated and network ready machines were not directly connected to the elements of Cloud Manufacturing and required human-in-the-loop. Addressing this gap, we introduced a new paradigm of Cyber-Physical Manufacturing Cloud (CPMC) that bridges a gap between physical machines and virtual space in 2017. CPMC virtualizes machine tools in cloud through web services …
Feasibility Of Electric Field Assisted Clogging Reduction In Cold Gas Spraying Nozzle, Hendric Tronsson
Feasibility Of Electric Field Assisted Clogging Reduction In Cold Gas Spraying Nozzle, Hendric Tronsson
ENGS 88 Honors Thesis (AB Students)
The relatively novel cold spraying process expands its range of applications constantly. In order to continue this trend, this process still has various hurdles that need to be overcome such as clogging. Clogging within the cold gas spraying process causes porous coatings with less material properties and lower durability; a solution is needed in order to reduce the clogging and so expand the cold gas spraying applications. This study aimed to explore the feasibility of using an electric field to reduce clogging. To do so a simplified channel was used to simulate charged particle trajectory shifts under the influence of …

Manufacturing Process Simulation – On Its Way To Industrial Application, Dennis Otten, Tobias A. Weber, Jan-Christoph Arent
International Journal of Aviation, Aeronautics, and Aerospace
Manufacturing process simulation (MPS) has become more and more important for aviation and the automobile industry. A highly competitive market requires the use of high performance metals and composite materials in combination with reduced manufacturing cost and time as well as a minimization of the time to market for a new product. However, the use of such materials is expensive and requires sophisticated manufacturing processes. An experience based process and tooling design followed by a lengthy trial-and-error optimization is just not contemporary anymore. Instead, a tooling design process aided by simulation is used more often. This paper provides an overview …

Photovoltaic Cooking In The Developing World, Tyler Watkins, Christopher O'Day, Omar Arriaga
Mechanical Engineering
The challenge of clean cooking is faced by hundreds of millions of people worldwide. We present a cooking technology consisting of a solar panel directly connected to an electric heater in a well-insulated chamber. Assuming continued decrease in solar panel prices, we anticipate that in a few decades Solar Electric Cooking technologies will be the most common cooking technology for the poor. Appropriate use of insulation reduces the power demand making low-power Insulated Solar Electric Cooking systems already cost competitive.

A Case Study Of Multiple-Use Finish Electrodes For Die-Sinking Edm, Troy A. Robertson
Masters Theses & Specialist Projects
This study examines the use of one finishing electrode to finish multiple dies without remachining the electrode. The multiple-use electrode finishing experiment in this study addresses technology in the die-forging industry. Methods of manufacturing spherical straight bevel forge gear dies have relied on die-sinking Electrical Discharge Machining (EDM) practices that showed great potential for advancement. The focus of this study is solely on the improvements of electrode use in EDM finishing-processes. The surface finish quality itself is not an area of concern other than maintaining that it does not diminish. The focused concern is maximizing the process by using one …

Loss On Ignition Using Infrared Heating, Benjamin J. Binoniemi
Masters Theses
The focus of this study is a proof of concept that infrared heating can be used to produce a reliable and rapid method of performing the loss on ignition test. The loss on ignition test is a foundry industry standard test that requires all moisture and volatile organic compounds be vaporized from a sample of foundry sand. The standard test as recommended by the American Foundry Society uses a muffle oven and requires nearly four hours to perform. This new concept performs the same test in approximately ten minutes. The biggest issues with the loss on ignition test are time …
Engineered Surface Properties Of Porous Tungsten From Cryogenic Machining, Julius M. Schoop
Engineered Surface Properties Of Porous Tungsten From Cryogenic Machining, Julius M. Schoop
Theses and Dissertations--Chemical and Materials Engineering
Porous tungsten is used to manufacture dispenser cathodes due to it refractory properties. Surface porosity is critical to functional performance of dispenser cathodes because it allows for an impregnated ceramic compound to migrate to the emitting surface, lowering its work function. Likewise, surface roughness is important because it is necessary to ensure uniform wetting of the molten impregnate during high temperature service. Current industry practice to achieve surface roughness and surface porosity requirements involves the use of a plastic infiltrant during machining. After machining, the infiltrant is baked and the cathode pellet is impregnated. In this context, cryogenic machining is …
