The Mars Desert Research Station - Erau Crew 160 Expedition, Lycourgos Manolopoulos, Ashley Hollis-Bussey, Hiroki Sugimoto, Cassandra Vella, John Herman, Marc Carofano Dec 2016

The Mars Desert Research Station - Erau Crew 160 Expedition, Lycourgos Manolopoulos, Ashley Hollis-Bussey, Hiroki Sugimoto, Cassandra Vella, John Herman, Marc Carofano

Student Works

The Mars Desert Research Station (MDRS) is a research program which is owned and operated by the Mars Society. The MDRS is located in Hanksville, Utah which hosts simulations that are typically two weeks long for professional scientists and engineers as well as college students of all levels, in training for human operations specifically on Mars. This space analog facility is in isolation, allowing for rigorous field studies regarding research that represents a true mission as if the crew members are conducting a real expedition on Mars. Participants are assigned specific roles and tasks that are typically aligned with their …


Optimizing Border Security With Stochastic And Deterministic Strategies, Gabriel A. Rueda Dec 2016

Optimizing Border Security With Stochastic And Deterministic Strategies, Gabriel A. Rueda

Theses and Dissertations

International trade and border security have always been linked together, and so has the need to find ways to improve security decisions. The United States and bordering countries benefit from the North American Free Trade Agreement (NAFTA), but amongst the positive effects of NAFTA there is a looming drug threat that effects the bi-national supply chains. In 2015 Customs and Border Protections (CBP) processed over 72,000 trucks, rail, and sea containers a day. CBP also seized 3.4 million pounds of narcotics, the majority of them at the ports of entry. With unknown threats using commercial vehicles to transport their illicit …


Safety Of Lithium Nickel Cobalt Aluminum Oxide Battery Packs In Transit Bus Applications, Timothy Cleary, Marc Serra Bosch, Jim Kreibick, Joel Anstrom Oct 2016

Safety Of Lithium Nickel Cobalt Aluminum Oxide Battery Packs In Transit Bus Applications, Timothy Cleary, Marc Serra Bosch, Jim Kreibick, Joel Anstrom

Mineta Transportation Institute

The future of mass transportation is clearly moving toward the increased efficiency and greenhouse gas reduction of hybrid and electric vehicles. With the introduction of high-power/high-energy storage devices such as lithium ion battery systems serving as a key element in the system, valid safety and security concerns emerge. This is especially true when the attractive high-specific-energy and power-chemistry lithium nickel cobalt aluminum oxide (NCA) is used. This chemistry provides great performance but presents a safety and security risk when used in large quantities, such as for a large passenger bus. If triggered, the cell can completely fuel its own fire, …


Using Everyday Objects To Engage Students In Standards Education, Margaret Phillips, Paul Mcpherson Oct 2016

Using Everyday Objects To Engage Students In Standards Education, Margaret Phillips, Paul Mcpherson

Libraries Faculty and Staff Presentations

This paper describes an innovative approach to standards education in an undergraduate mechanical engineering technology design course. The work is focused on making standards appeal to students by using “everyday objects” (e.g. toaster, ladder, grill, etc.) as catalysts to introduce the topic of standards in a way that connects to students’ daily lives. The project involves instructor-librarian collaboration to incorporate information literacy and campus library resources into the standards curricula, so that students not only become familiar with standards resources, but also proficient at searching for and locating the documents. Preliminary results and observations indicate this is an effective approach …

Portable Sensory Room For The West Orange County Consortium For Special Education, Lindsey Chase, Emma Eskildsen, Alex Fox, Claire Francis, Nate Hoffman, Kaylee Keck, Sarah Sullivan Jun 2016

Portable Sensory Room For The West Orange County Consortium For Special Education, Lindsey Chase, Emma Eskildsen, Alex Fox, Claire Francis, Nate Hoffman, Kaylee Keck, Sarah Sullivan

Biomedical Engineering

This report discusses the development of a Portable Sensory Room to be used at Newland Elementary School in Huntington Beach. Newland Elementary has an exceptional Special Needs program that teaches the children with the most severe cases of autism in its school district. People with autism typically also have sensory processing disorders, which can be extremely disruptive for a child’s development and can make it difficult for a child to be able to concentrate long enough to gain necessary life skills. The idea behind a Sensory Rooms is to create a place to calm the students and to expose them …


Advances In Repurposing And Recycling Of Post-Vehicle-Application Lithium-Ion Batteries, Charles R. Standridge, Lindsay Corneal, Nicholas Baine May 2016

Advances In Repurposing And Recycling Of Post-Vehicle-Application Lithium-Ion Batteries, Charles R. Standridge, Lindsay Corneal, Nicholas Baine

Mineta Transportation Institute

Increased electrification of vehicles has increased the use of lithium-ion batteries for energy storage, and raised the issue of what to do with post-vehicle-application batteries. Three possibilities have been identified: 1) remanufacturing for intended reuse in vehicles; 2) repurposing for non-vehicle, stationary storage applications; and 3) recycling, extracting the precious metals, chemicals and other byproducts. Advances in repurposing and recycling are presented, along with a mathematical model that forecasts the manufacturing capacity needed for remanufacturing, repurposing, and recycling. Results obtained by simulating the model show that up to a 25% reduction in the need for new batteries can be achieved …


Covert Contrast: The Acquisition Of Mandarin Tone 2 And Tone 3 In L2 Production And Perception, Liya Mar May 2016

Covert Contrast: The Acquisition Of Mandarin Tone 2 And Tone 3 In L2 Production And Perception, Liya Mar

Theses and Dissertations

This dissertation investigates the occurrence of an intermediate stage, termed a covert contrast, in the acquisition of Mandarin Tone 2 (T2) and Tone 3 (T3) by adult speakers of American English. A covert contrast is a statistically reliable distinction produced by language learners that is not perceived by native speakers of the target language (TL). In second language (L2) acquisition, whether a learner is judged as having acquired a TL phonemic contrast has largely depended on whether the contrast was perceived and transcribed by native speakers of the TL. However, categorical perception has shown that native listeners cannot perceive a …


Stop Identity Cues As A Cue To Language Identity, Paula Lisa Castonguay Jan 2016

Stop Identity Cues As A Cue To Language Identity, Paula Lisa Castonguay

Wayne State University Dissertations

The purpose of the present study was to determine whether language membership could potentially be cued by the acoustic-phonetic detail of word-initial stops and retained all the way through the process of lexical access to aid in language identification. Of particular interest were language-specific differences in CE and CF word-initial stops. Experiment 1 consisted of an interlingual homophone production task. The purpose of this study was to examine how word-initial stop consonants differ in terms of acoustic properties in Canadian English (CE) and Canadian French (CF) interlingual homophones. The analyses from the bilingual speakers in Experiment 1 indicate that bilinguals …
