Scale Dependence Of Cloud Microphysical Response To Turbulent Entrainment And Mixing, Bipin Kumar, Paul Gotzfried, Neethl Suresh, Jörg Schumacher, Raymond Shaw

Michigan Tech Publications, Part 1

The dynamics and lifetime of atmospheric clouds are tightly coupled to entrainment and turbulent mixing. This paper presents direct numerical simulations of turbulent mixing followed by droplet evaporation at the cloud‐clear air interface in a meter‐sized volume, with an ensemble of up to almost half a billion individual cloud water droplets. The dependence of the mixing process on domain size reveals that inhomogeneous mixing becomes increasingly important as the domain size is increased. The shape of the droplet size distribution varies strongly with spatial scale, with the appearance of a pronounced negative exponential tail. The increase of relative dispersion during …

On The Asymmetry Between Upward And Downward Field-Aligned Currents Interacting With The Ionosphere, A. V. Streltsov

Publications

The paper presents results from the numerical study of the magnetosphere-ionosphere interactions driven by the large-scale electric field in the magnetically conjugate, high-latitude regions of northern and southern hemispheres. Simulations of the two-fluid MHD model demonstrate that these interactions can lead to a generation of a system of small-scale, intense field-aligned currents with a significant difference in size and amplitude between the upward and downward currents. In particular, in both hemispheres, the downward currents (where the electrons are flowing from the ionosphere) become more narrow and intense than the adjacent upward currents. At high latitudes, the field-aligned currents are closely …

Results Of Webt, Vlba And Rxte Monitoring Of 3c 279 During 2006-2007, Niall Smith, Et. Al.

Blackrock Castle Observatory Publications

Context. The quasar 3C 279 is among the most extreme blazars in terms of luminosity and variability of flux at all wavebands. Its variations in flux and polarization are quite complex and therefore require intensive monitoring observations at multiple wavebands to characterise and interpret the observed changes.

Aims. In this paper, we present radio-to-optical data taken by the WEBT, supplemented by our VLBA and RXTE observations, of 3C 279. Our goal is to use this extensive database to draw inferences regarding the physics of the relativistic jet.

Methods. We assemble multifrequency light curves with data from 30 ground-based observatories and …

On The Existence Of Ionospheric Feedback Instability In The Earth’S Magnetosphere-Ionosphere System, Anatoly V. Streltsov, Evgeny V. Mishin

Publications

The ionospheric feedback instability (IFI) has been considered one of the main generation mechanisms for large-amplitude ultralow frequency waves and small-scale field-aligned currents in the auroral and subauroral regions for more than 40 years. Sydorenko and Rankin (2017, https://doi.org/10.1002/2017GL073415) have recently challenged the very existence of the IFI for any realistic geophysical conditions in the Earth's ionosphere-magnetosphere system. Because this conclusion contradicts numerous theoretical, numerical, and experimental works successfully used IFI to explain and predict results from observations for more than four decades, it deserves special attention. We show that this conclusion is mainly based on the specific ionospheric …

How Songbirds Learn To Sing Provides Suggestions For Designing Team Projects For Computing Courses, Ashwin Satyanarayana, Radhika Natarajan, Lior Baron

Publications and Research

Understanding how our brain works and how we learn is perhaps one of the greatest challenges facing twenty-first computer science. Songbirds are good candidates for trying to unravel some of this mystery. Over the last decade, a large amount of research has been made to better understand how songbirds learn complex songs. The Canary (Serinus canaria) and the Zebra Finch (Taeniopygia guttata) have been widely used bird models to study these brain and behavior relationships. Like songbirds, we humans are vocal and social learners. In such learners, the development of communication is initially steered by social interactions with adult tutors. …

Molten-Salt Synthesis Of Complex Metal Oxide Nanoparticles, Jose P. Zuniga, Maya Abdou, Santosh K. Gupta, Yuanbing Mao

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Chemistry)

The development of feasible synthesis methods is critical for the successful exploration of novel properties and potential applications of nanomaterials. Here, we introduce the molten-salt synthesis (MSS) method for making metal oxide nanomaterials. Advantages over other methods include its simplicity, greenness, reliability, scalability, and generalizability. Using pyrochlore lanthanum hafnium oxide (La2Hf2O7) as a representative, we describe the MSS protocol for the successful synthesis of complex metal oxide nanoparticles (NPs). Furthermore, this method has the unique ability to produce NPs with different material features by changing various synthesis parameters such as pH, temperature, duration, and post-annealing. By fine-tuning these parameters, we …

P-43 Doing Astronomy With Gravitational Waves, Tiffany Summerscales

Celebration of Research and Creative Scholarship

With the first detection of gravitational waves on September 14, 2015, the new era of gravitational wave astronomy began. Gravitational wave detections, along with observations made by optical telescopes, have given us new information about the universe. This includes new estimates of the numbers of black holes in the universe and their properties, as well as confirming theories about the sources of some gamma ray bursts and how those sources produce heavy elements.

Fatal General Aviation Accidents In Furtherance Of Business (1996–2015): Rates, Risk Factors, And Accident Causes, Scott Burgess, Stewart Boyd, Douglas Boyd

Journal of Aviation Technology and Engineering

Introduction: General aviation missions related to furtherance of business potentially carry higher risk (operations in adverse weather, at night, for longer distances) than those undertaken for recreation. The study herein was undertaken to determine fatal accident rates, proportions, and risk factors/causes.

Method: The National Transportation Safety Board aviation accident database was queried for accidents (1996–2015). Annual fleet times were from the general aviation annual activity survey. Statistical analyses used Poisson distributions, proportion testing, and Cohen’s Kappa tests.

Results: The fatal accident rate for business operations was three- to six-fold lower than the rate for recreational flights with a decline evident …

Primary Emissions Of Glyoxal And Methylglyoxal From Laboratory Measurements Of Open Biomass Burning, Kyle J. Zarzana, Vanessa Selimovic, Abigail R. Koss, Kanako Sekimoto, Matthew M. Coggon, Bin Yuan, William P. Dubé, Robert J. Yokelson, Carsten Warneke, Joost A. De Gouw, James M. Roberts, Steven S. Brown

Chemistry and Biochemistry Faculty Publications

We report the emissions of glyoxal and methylglyoxal from the open burning of biomass during the NOAA-led 2016 FIREX intensive at the Fire Sciences Laboratory in Missoula, MT. Both compounds were measured using cavity-enhanced spectroscopy, which is both more sensitive and more selective than methods previously used to determine emissions of these two compounds. A total of 75 burns were conducted, using 33 different fuels in 8 different categories, providing a far more comprehensive dataset for emissions than was previously available. Measurements of methylglyoxal using our instrument suffer from spectral interferences from several other species, and the values reported here …

Statistical Monitoring Of Queuing Networks, Yaren Bilge Kaya

USF Tampa Graduate Theses and Dissertations

Queuing systems are important parts of our daily lives and to keep their operations at an efficient level they need to be monitored by using queuing Performance Metrics, such as average queue lengths and average waiting times. On the other hand queue lengths and waiting times are generally random variables and their distributions depend on different properties like arrival rates, service times, number of servers. We focused on detecting the change in service rates in this report. Therefore, we monitored queues by using Cumulative Sum(CUSUM) charts based on likelihood ratios and compared the Average Run Length values of different service …

More Than Free: Equity In Open Educational Resources, Nicole Williams, Kathryn Anastasi

Open Educational Resources

Faculty creation and adoption of OER and ZTC materials can provide students with benefits that extend beyond no-cost or low-cost considerations. These materials can be the foundation of more culturally relevant classroom materialsthanstudents are used to seeing. They can increase the accessibility of instructional materials to students with disabilities. They can be employed to support student-centered learning ideas which upend traditionalnotionshow information flows between teachers and students. Using OER and ZTC materials has the potential to address many of the concerns about inequality that faculty and students alike have about the current educational model. Although OER and ZTC initiatives present …

From The River To The Gulf: An Investigation Of Biogeochemical Cycling In Wetland Soils And Coastal Shelf Sediments, Katie Bowes

LSU Master's Theses

Louisiana is home to 40% of the coastal wetlands in the lower 48 states, yet accounts for 80% of the coastal wetland loss in this region. This loss is attributed to decreased sediment supply, levee alteration, sea level rise, channelization, and subsidence. The levee system in Louisiana disconnected coastal wetlands from the main stem of the Mississippi River (MSR), reducing the amount of land-building sediment that reaches coastal wetlands. This disconnection also allows a greater percentage of river discharge, including agricultural contaminants and runoff, to flow into the northern Gulf of Mexico (NGOM).

The 2012 Coastal Master Plan proposed eight …
