Coupling Community Preferences With Hydrologic Evaluation Of Low Impact Development Implementation In An Urban Watershed, Corinna M. Fleischmann, Carol Atkinson-Palombo, Joseph T. Bushey, Eric D. Jackson, David W. Payne

Suburban Sustainability

Stormwater runoff, and its associated pollutants, is a major problem in urban watersheds where the runoff is either channeled into surface water bodies or wastewater treatment plants. One emerging Best Management Practice (BMP) to control stormwater runoff is low impact development (LID). The EPA Stormwater Management Model (SWMM) was used to evaluate the hydrologic effectiveness at a watershed scale of five LID technologies (vegetated swales, bioretention cells, porous pavement, rain barrels and tree boxes) in an existing, typical urban watershed. As implementation focused on public transportation areas, hydrologic effectiveness of runoff reduction was assessed as a function of roadway length: …

Finite Element Modeling Of Shallow Embedded Connection Stiffness, Trevor Jones, Dr. Paul Richards

Journal of Undergraduate Research

Shallowly embedded connections are a common and important connection of steel columns to reinforced concrete foundations, which can increase the building’s overall stiffness and strength. Until now, their contributions have been neglected because they are hard to quantify and study. Previous research at BYU (Barnwell 2015) has shown that the strength and stiffness available in these connections is greater than was previously assumed. A thorough understanding of these desirable properties would allow engineers to design buildings that are more cost-effective.

Thermal Properties Of Natural-Colored And Darkened Portland Cement Concrete Pavement, Tenli Waters, W. Spencer Guthrie

Journal of Undergraduate Research

The purpose of this project was to measure thermal properties of natural-colored and darkened portland cement concrete in order to explain observations from field data already collected. While portland cement concrete pavement offers a durable surface and long service life when designed and constructed properly, selected concrete pavement sections require expensive winter maintenance treatments to clear snow and ice. One method of potentially reducing winter maintenance costs is darkening the concrete pavement. Darkening the concrete reduces its albedo, or whiteness, and should therefore promote higher pavement surface temperatures through increased absorption of radiation energy from the sun. In winter, darkened …

Journal of Undergraduate Research

NASA’s Decadal Survey emphasizes the importance of soil moisture measurements, citing their significance in predicting natural hazards and the role of soil moisture levels in the water and carbon cycles [1]. Soil moisture estimates are used for a variety of applications including drought detection, flood and landslide forecasts, crop yield monitoring, and rain precipitation models [1]–[4]. Orbiting sensors provide an effective way to measure soil moisture globally because measurements of each area can be taken at a relatively high revisit frequency (typically one to two days). These sensors are generally able to measure soil moisture parameters despite cloud coverage and, …

Single Ion Detection For Mass Spectrometry Using Low Capacitance Mosfets, Matthew Hamblin, Aaron Hawkins

Journal of Undergraduate Research

Mass spectrometry is an important tool for analytical chemistry that allows the chemical composition of a compound to be determined. In order to do so, it separates the compound into ions, and then detects the number of ions of different masses.

The charge on a single ion is very small, making it difficult to measure. In order to overcome this, current mass spectrometers must use methods such as electron multipliers to create a cascading effect of electrons until a measurable charge is reached or cryodetectors that measure the thermal change of an ion hit at low temperatures.¹ Using methods …

Comparison Of Renting Training Aircraft Using Data Envelopment Analysis, Heather Dickerson

Undergraduate Review

Many elements are involved when a pilot is trying to decide which aircraft to pursue for rental. Uninformed new pilots decide to rent purely based upon the aircraft used for initial training, but once more variables are considered, the pilot will realize such an important decision must consider all aspects. Cost typically being the greatest determining factor, horsepower output of the engine, speed, the maximum load capacity, and the maximum altitude the aircraft is able to reach also tend to have a large effect on determining which aircraft will suit the needs of the pilot. Data Envelopment Analysis was used …

Fast And De-Noise Support Vector Machine Training Method Based On Fuzzy Clustering Method For Large Real World Datasets, Omid Naghash Almasi, Modjtaba Rouhani

Turkish Journal of Electrical Engineering and Computer Sciences

Classifying large and real-world datasets is a challenging problem in machine learning algorithms. Among the machine learning methods, the support vector machine (SVM) is a well-known approach with high generalization ability. Unfortunately, while the number of training data increases and the data contain noise, the performance of SVM significantly decreases. In this paper, a fast and de-noise two-stage method for training SVMs to deal with large, real-world datasets is proposed. In the first stage, data that contain noises or are suspected to be noisy are identified and eliminated from the genuine training dataset. The process of elimination and identification is …
