Use of NOAA-N satellites for land/water discrimination and flood monitoring
A tool for monitoring the extent of major floods was developed using data collected by the NOAA-6 advanced very high resolution radiometer (AVHRR). A basic understanding of the spectral returns in AVHRR channels 1 and 2 for water, soil, and vegetation was reached using a large number of NOAA-6 scenes from different seasons and geographic locations. A look-up table classifier was developed based on analysis of the reflective channel relationships for each surface feature. The classifier automatically separated land from water and produced classification maps which were registered for a number of acquisitions, including coverage of a major flood on the Parana River of Argentina
Digital Therapeutics for Mental Health: Is Attrition the Achilles Heel?
Digit therapeutics are novel software devices that clinicians may utilize in
delivering quality mental health care and ensuring positive outcomes. However,
uptake of digital therapeutics and clinically tested software-based programs
remains low. This article presents possible reasons for attrition and low
engagement in clinical studies investigating digital therapeutics, analyses of
studies in which engagement was high, and design constructs that may encourage
user engagement. The aim is to shed light on the importance of real-world
attrition data of digital therapeutics, and important characteristics of
medical devices that have positively influenced user engagement. The findings
presented in this article will be useful to relevant stakeholders and medical
device experts tasked with addressing the gap between software medical design
and user engagement present in digital therapeutic clinical trials.Comment: 11 pages, 1 tabl
The effect of switching mobile sources to natural gas on the ozone in the great smoky mountains national park
Mobile sources are among the largest contributors of NOx in the Great Smoky Mountains National Park region (GSMNP). In 2001, these sources contributed 45% of NOx emissions. From 1990 to 2001, the growth of vehicle miles traveled (VMT) increased 60% and 55% in neighboring Sevier and Blount counties respectively. These emissions combined with the high volatile organic compounds (VOC) emissions in the Southeast area have caused the ozone ground level concentration to be as high as some major metropolitan areas in the summer season. In 2001, the maximum 8-hr ozone concentration inside the park was 103 parts per billion. In response to high ozone levels in other areas, federal, state, and local governments are promoting the use of alternative, clean, and reformulated fuel vehicles as a means to improve local air pollution. One of these fuels is compressed natural gas (CNG). The purpose of this project was to use USEPA's CMAQ system in order to model the air quality and compare the ozone ground level formation in the GSMNP from light duty vehicles (LDVs) operating with 100% CNG within 100 miles around GSMNP. A severe southeast ozone episode between August and September 1999 was used as a reference and 2004 was used as a future case. Results showed that LDVs fueled with 100% CNG in the domain could reduce ozone level by 10% and 8% for 1-hr and 8-hr ozone formation respectively in the GSMNP on the modeled time period. Scavenging occurred around the GSMNP in the morning time during the selected episode
