Co2 Conversion Over Supported Coni Bimetallic And Conipd Trimetallic Catalyst Via Dry Reforming With Methane, Scott Bamonte

Discovery Day (formerly Post & Beyond)

Greenhouse gas emission is a problem for the earth, and is causing warming

of the climate, and acidification of the oceans. The primary objective of

this project is to develop novel cobalt based catalysts, to enhance catalytic

conversion of CO₂ by methane into, value added chemicals and fuels. The

heterogeneous Co-based bimetallic and tri metallic catalysts were synthesized

via a wet incipient impregnation method to uniformly coat the metal

salts to the pre-treated support (TiO₂, SiO₂, and La-ZrO₂). The catalyst was

dried in the oven at 80∞ C for two hours before subjected …

Applications Of Groebner Bases In Commutative Algebra And Algebraic Geometry, Christopher Guevara

Discovery Day (formerly Post & Beyond)

An ideal I in a polynomial ring k[x1,...,xn] is a nonempty set closed under

addition satisfying hf _ I whenever h _ k[x1,...,xn] and f _ I. We say I is finitely

generated if there exist f1,...,fs _ I such that every element of I is of the form

h1f1+ΣΣΣ+hsfs for some h1,...,hs _ k[x1,...,xn]. By a fundamental result called

the Hilbert Basis Theorem, every polynomial ideal is finitely generated. Every

polynomial ideal has a special finite generating set called a Groebner basis.

A Groebner basis {g1,...,gt} is a set of polynomials in I such that the ideal

generated by …

Solar Eclipse Induced Atmospheric Turbulence Effects On High Altitude Balloons, Fnu Anamika, Denise Buckner, Peter Henson, Jennifer Fowler, Nanette Valentour

2017 Academic High Altitude Conference

The North Dakota Atmospheric Education Student Initiated Research (ND-AESIR) team launched a balloon during the total solar eclipse in Rexburg, Idaho. After the umbra’s passage, the balloon experienced unexpectedly high levels of atmospheric turbulence. Video footage taken from the payload displays the conditions, and analysis of flight path data models created from the iridium GPS confirm that unusually violent turbulence occurred. These forces caused the key rings holding the bottom of the parachute to the payload train to rip open; the balloon and parachute flew away and the payloads free fell to the surface from an altitude of 68,301 feet. …

Physoon - Radiation Detection In Various High Altitude Environments, Christopher Helmerich

2017 Academic High Altitude Conference

Physoon is a high altitude ballooning payload designed and built by members of the Space Hardware Club for the purpose of comparing cosmic and terrestrial radiation from a variety of environmental conditions, including clear days, night times, solar events (eclipses, solar flares, coronal mass ejections), and thunderstorms. Over three design iterations, Physoon has flown eleven times with various combinations of Geiger counters sensors: a low energy Alpha-Beta-Gamma detector, an unshielded high-energy Beta-Gamma detector, and a shielded high-energy Beta-Gamma detector. One of these iterations successfully recovered data from high altitude during totality of the Great American Solar Eclipse. Another iteration was …

Measurement Of Speed Of Sound Profile Using Laaces Balloon, Zhuang Li, Brett Schaefer, Brian Schaefer, William Dever, Tyler Morgan, Matthew Foltz

2017 Academic High Altitude Conference

The goal of this mission is to test the speed of sound at different altitudes and ultimately at a maximum height of 100,000 feet (30 km). In conjunction with this testing, environmental parameters including temperature, pressure, and humidity are measured and used to calculate the speed of sound to compare to the measured results. The team constructed the payload “Dorothy” using polystyrene foam due to its lightweight and thermal isolation property. An ultrasonic sensor with a reflection mirror were installed outside payload box to measure speed of sound. All the sensors were calibrated. Software for the project was developed in …

Calibration Of Temperature Sensors In Preparation For The 2017 Total Solar Eclipse, Erick Agrimson, Kaye Smith, Ana Taylor, Vina Onyango-Robshaw, Rachel Lang, Alynie Xiong, Peace Sinyigaya, Grace Maki, Rachel Dubose, Brittany Craig, James Flaten, Gordon Mcintosh

2017 Academic High Altitude Conference

In preparation for the 2017 total solar eclipse, St. Catherine University developed a calibration protocol for the temperature sensors flown during thermal wake boom experiments. The calibration method used a standard two-point technique that corrected each individual sensor for both slope and offset errors using a high quality NIST certified thermocouple as the temperature standard. Our method is not absolute but corrects each sensor relative to the NIST standard so that we feel some confidence that individual sensor variations are mitigated. In preparation for the eclipse, calibration curves were generated for over 200 individual digital and thermistor temperature sensors.

Data Analysis And Curve Fitting To Determine The Regener-Pfotzer Maximum, Liam Taylor, Gordon Mcintosh, Alaina Swanson, Erick Agrimson, Kaue Smith

2017 Academic High Altitude Conference

Various data analysis methods were explored to more accurately and consistently determine the Regener-Pfotzer (RP) maxima for high altitude cosmic radiation. The radiation has been measured during 15 balloon flights using Geiger counters with five second accumulation times. Of the 15 flights, 10 of them included omni-directional counts data, and 8 of them included vertical coincidence counts data. Count data from altitudes greater than 10 km were analyzed to determine the maxima. The data analysis methods used were moving average filtering and summation of Geiger counts into one minute intervals. Moving average filtering did not give reliable results, so the …

Use And Implementation Of The Automatic Packet Reporting System (Aprs) On High Altitude Payloads., Sam Fink, Robert Moody, Carson Keeter, Cassandra Runyon, Cyndi Hall

2017 Academic High Altitude Conference

Once a weather balloon enters the uncontrollable realm of nature upon release it is subject to a high degree of freedom and flight path options. Passive tracking methods become essential to physically follow the trajectory, the balloon, and its payload. The Automatic Packet Reporting System (APRS) provides an ideal platform for tracking high-altitude and low earth orbit instrumentation because at zenith there is no radio horizon. Demonstrated aboard the International Space Station, this simple system provides the maximum tracking range at very low power and cost with very high accuracy, by utilizing existing federally funded infrastructure. An amateur radio license …

Pressure Regulator For A High Altitude Balloon, Kala Brown, Darci Snowden, Joe Cuthbertson, Jessica Kisner, Addison Wenger

2017 Academic High Altitude Conference

High altitude balloons are large latex balloons filled with gas that carry a payload to near space. Because they can travel to around 100,000 feet, they provide a convenient way to study the Earth’s atmosphere. Per Boyle’s Law, the pressure and volume of a confined gas are inversely proportional. Thus, as the balloon ascends and the atmospheric pressure decreases, the gas inside the balloon expands. This pressure difference allows the balloon to ascend, but it also causes it to continuously expand until it bursts. For some observations, one might want their balloon to remain at about the same altitude for …

Controlled Heading Automation Device, Robert Coulson

2017 Academic High Altitude Conference

One of the most significant limitations of weather balloon-based data collection is that instruments and payloads cannot depend on particular orientations or predictable rotation. Several investigators have used payload heading control devices to overcome this limitation in order to collect directional data and record motion controlled video footage. The work described in this presentation builds on the Controlled Heading Automation Device (CHAD) developed by Kruger et al. (2016) and was carried out at DePaul University in summer 2017 as an undergraduate research project. Our goal was to record stable video of the shadow of the moon on Earth’s surface during …

A Survey Of Current Balloon Trajectory Prediction Technology, Luke W. Renegar

2017 Academic High Altitude Conference

High-altitude scientific balloons allow for very little control over their trajectories. Although systems exist to influence the burst altitude of the balloons, their horizontal motion is dictated solely by the vagrancies of the wind. The accurate prediction of balloon trajectories is thus a topic of great importance to flight operations personnel, since launch/no-launch decisions must be made based on the likelihood of the balloon landing in some undesirable location. Such concerns are particularly acute in areas with high population densities or significant areas of restricted airspace, both of which are prevalent in the Mid-Atlantic region. This paper presents an overview …

Eclipse Ballooning Stem Outreach For Elementary, Middle, And High School Education, Peter Henson, Fnu Anamika, Denise Buckner, Marissa Saad, Caitlin Nolby

2017 Academic High Altitude Conference

To promote Science, Technology, Engineering and Mathematics (STEM) education through ballooning, the North Dakota Space Grant Consortium (NDSGC) organizes an annual Near-Space Balloon Competition (NSBC) for students in grades 6 - 12. Students across the state of North Dakota have the opportunity to launch experiments into a near- space environment. The students learn how to write proposals, design payloads, and analyze data. They learn through an active, inquiry-based style that will prepare them for real-world engineering and critical thinking jobs. In 2016, NSBC proposed Great American Eclipse as the theme for the competition, thus the students were focused on designing …

Impactful Practice: Lessons Learned Through Ballooning Outreach, Tracy Knowles, Leandro Braga, Alex Eberle, Tom Busby, John Paul Beard, Jessica Glasscock, Jacolby Gardner, Matt Smither

2017 Academic High Altitude Conference

The goal of Bluegrass Community and Technical College’s (BCTC) Eclipse Outreach Ambassador Project was to get students across the Bluegrass excited and educated about the 2017 total solar eclipse. Several years ago the BalloonSat Project was started to provide hands-on earth and atmospheric science experiences to BCTC students. In linking the two initiatives, we allowed BCTC BalloonSat team members to continue learning to design, build, test, fly and retrieve balloon-borne payloads while using a novel method by which to engage local elementary and middle school students in learning more about and anticipating the upcoming eclipse. Eclipse practice flights carried payloads …

Placing A High-Altitude Balloon In The Path Of Totality, Nicholas Jordan, Christopher Helmerich

2017 Academic High Altitude Conference

The UAH Space Hardware Club had conducted 70 flights prior to the Eclipse. In this time, we have gained valuable skills and experience which we have put into practice and passed on through the years. We put these skills into practice for the Eclipse. Our first challenge was finding where to launch. We started out by looking for suitable locations inside totality. We also examined a map of totality at 80,000 ft. We then ran predictions based on past weather during that time of year. By compiling multiple past predictions, we eliminated possible launch sites. We had multiple payloads, some …

Single Versus Concurrent Systems: Nominal Classification In Mian, Greville G. Corbett, Sebastian Fedden, Raphael Finkel

Computer Science Faculty Publications

The Papuan language Mian allows us to refine the typology of nominal classification. Mian has two candidate classification systems, differing completely in their formal realization but overlapping considerably in their semantics. To determine whether to analyse Mian as a single system or concurrent systems we adopt a canonical approach. Our criteria – orthogonality of the systems (we give a precise measure), semantic compositionality, morphosyntactic alignment, distribution across parts of speech, exponence, and interaction with other features – point mainly to an analysis as concurrent systems. We thus improve our analysis of Mian and make progress with the typology of nominal …
