During applied signal-detection (e.g., airport-baggage screening) human operators can be assisted in their decision-making process by automated devices. Automation implementation is aimed at increasing performance relative to unaided levels. Generally, this intended effect is empirically observed. However, operators consistently fall short of optimal levels of aided performance, indicating suboptimal aid-use...
Chloride-induced corrosion is one of the primary causes of the degradation of reinforced steel in concrete structures. Currently, the rapid chloride permeability test (RCPT) is the most specified method to determine the concrete’s resistivity to chloride ingress, thus a determining factor in assessing the durability of concrete. While it is...
Multimorbidity, or the concurrent presence of two or more chronic conditions, significantly increases the risk of adverse health outcomes, particularly for adults age 65 and older. Psychosocial, behavioral and social factors can further exacerbate the impact of multimorbidity, but are infrequently and inconsistently documented within electronic health records (EHRs). Research...
The purpose of this study was to examine the validity and reliability of the 30-minute cycling time trial to estimate the heart rate at lactate threshold. Recreationally trained cyclists and triathletes (n = 47) performed 3 tests in random order: 1) One graded exercise test to directly determine lactate threshold...
Low concentrations of dissolved copper have proven to be harmful to a number of aquatic organisms, with recent research highlighting detrimental effects to endangered salmonid species. Stormwater runoff can represent a significant source of copper to surface waters, necessitating cost-effective alternatives to current stormwater best management practices (BMPs). This study...
Fundraising in the 21st century is becoming an increasingly important component of rural community colleges' (RCCs) overall funding strategies. Alumni represent a significant population of potential college supporters. The problem facing rural community colleges involves fiscal viability through developing innovative fundraising practices and identifying emerging sources of additional revenue. The...
We identify all translation covers among triangular billiards surfaces. Our main tools are the J-invariant of Kenyon and Smillie and a property of triangular billiards surfaces, which we call fingerprint type, that is invariant under balanced translation covers.
Wave-induced circulation is the defining characteristic of the nearshore. Within this region, the constant feedback cycle between incoming waves, wave-generated currents, and the mobile sediment bed is responsible for the evolution of complex patterns in nearshore and beach morphology. Central to our understanding of this system is knowledge of the...
An experimental study of the near-field flow structure produced by an incompressible turbulent Acoustically Self-Excited Jet (ASEJ) in a large enclosure using Particle Image Velocimetry (PIV) is presented. The salient feature of this jet is that it provides an increase in near-field mixing and turbulence without additional external power input....
