Biomass harvest of invasive Typha promotes plant diversity in a Great Lakes coastal wetland

Creator:: Lishawa, Shane C., Lawrence, Beth A., Albert, Dennis A., and Tuchman, Nancy C.
Abstract:: Ecological and financial constraints limit restoration efforts, preventing the achievement of desired ecological outcomes. Harvesting invasive plant biomass for bioenergy has the potential to reduce feedback mechanisms that sustain invasion, while alleviating financial limitations. Typha × glauca is a highly productive invasive wetland plant that reduces plant diversity, alters ecological...

A Novel Fuel Performance Index for Low-Temperature Combustion Engines Based on Operating Envelopes in Light-Duty Driving Cycle Simulations

Creator:: Niemeyer, Kyle E., Daly, Shane R., Cannella, William J., and Hagen, Christopher L.
Abstract:: Low-temperature combustion (LTC) engine concepts such as homogeneous charge compression ignition (HCCI) offer the potential of improved efficiency and reduced emissions of NOₓ and particulates. However, engines can only successfully operate in HCCI mode for limited operating ranges that vary depending on the fuel composition. Unfortunately, traditional ratings such as...

Investigation of the LTC fuel performance index for oxygenated reference fuel blends

Creator:: Niemeyer, Kyle E., Daly, Shane R., Cannella, William J., and Hagen, Christopher L.
Abstract:: A new metric for ranking the suitability of fuels in LTC engines was recently introduced, based on the fraction of potential fuel savings achieved in the FTP-75 light-duty vehicle driving cycle. In the current study, this LTC fuel performance index was calculated computationally and analyzed for a number of fuel...

Predicting fuel research octane number using Fourier-transform infrared absorption spectra of neat hydrocarbons

Creator:: Daly, Shane R., Niemeyer, Kyle E., Cannella, William J., and Hagen, Christopher L.
Abstract:: Liquid transportation fuels require costly and time-consuming tests to characterize metrics, such as Research Octane Number (RON) for gasoline. If fuel sale restrictions requiring use of standard Cooperative Fuel Research (CFR) testing procedures do not apply, these tests may be avoided by using multivariate statistical models to predict RON and...

Fourier-Transform Infrared Absorption Spectroscopy in Binary Hydrocarbon-Alcohol Single Droplet Evaporation

Creator:: Daly, Shane R., Olson, Nicholas, and Hagen, Christopher L.
Abstract:: Broadband absorption spectroscopy, by way of FTIR, was used to investigate the vapor cloud of a single millimeter sized liquid droplet suspended by a syringe as it evaporates at standard conditions. Single beam data were collected every 8 seconds resulting in a time-resolved record. Species concentrations were tracked using their...

Traffic Signal System Misconceptions Across Three Cohorts: Novice Students, Expert Students, and Practicing Engineers

Creator:: Hurwitz, David S., Brown, Shane, Islam, Mohammad, Daratha, Kelvin, and Kyte, Michael
Abstract:: Theories of situated knowledge and research evidence suggest that students are not prepared for the engineering workforce upon graduation from engineering programs. Concept inventory results from diverse fields suggest that students do not understand fundamental engineering, mathematics, and science concepts. These two concerns may result from different knowledge deficiencies; one...

Influence of Collaborative Curriculum Design on Educational Beliefs, Communities of Practitioners, and Classroom Practice in Transportation Engineering Education

Creator:: Hurwitz, David S., Swake, Joshua, Brown, Shane, Young, Rhonda, Heaslip, Kevin, Sanford Bernhardt, Kristen L., and Turochy, Rod E.
Abstract:: The development and widespread implementation of best practices in transportation engineering classrooms is important in attracting and retaining the next generation of transportation engineers. Engineering education professionals have uncovered many best practices in the field; however, the process of effectively disseminating and ultimately achieving the widespread adoption of these best...

In Situ Chemical Characterization of Aged Biomass-Burning Aerosols Impacting Cold Wave Clouds

Creator:: Pratt, Kerri A., Heymsfield, Andrew J., Twohy, Cynthia, Murphy, Shane M., DeMott, Paul J., Hudson, James G., Subramanian, R., Wang, Zhien, Seinfeld, John H., and Prather, Kimberly A.
Abstract:: During the Ice in Clouds Experiment–Layer Clouds (ICE-L), aged biomass-burning particles were identified within two orographic wave cloud regions over Wyoming using single-particle mass spectrometry and electron microscopy. Using a suite of instrumentation, particle chemistry was characterized in tandem with cloud microphysics. The aged biomass-burning particles comprised ~30%–40% by number...

Abstract:: During the Ice in Clouds Experiment‐Layer Clouds (ICE‐L), dry lakebed, or playa, salts from the Great Basin region of the United States were observed as cloud nuclei in orographic wave clouds over Wyoming. Using a counterflow virtual impactor in series with a single‐particle mass spectrometer, sodium‐potassium‐magnesium‐calcium‐chloride salts were identified as...
