Download or read book Improving Characterization of Anthropogenic Methane Emissions in the United States written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-08-25 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding, quantifying, and tracking atmospheric methane and emissions is essential for addressing concerns and informing decisions that affect the climate, economy, and human health and safety. Atmospheric methane is a potent greenhouse gas (GHG) that contributes to global warming. While carbon dioxide is by far the dominant cause of the rise in global average temperatures, methane also plays a significant role because it absorbs more energy per unit mass than carbon dioxide does, giving it a disproportionately large effect on global radiative forcing. In addition to contributing to climate change, methane also affects human health as a precursor to ozone pollution in the lower atmosphere. Improving Characterization of Anthropogenic Methane Emissions in the United States summarizes the current state of understanding of methane emissions sources and the measurement approaches and evaluates opportunities for methodological and inventory development improvements. This report will inform future research agendas of various U.S. agencies, including NOAA, the EPA, the DOE, NASA, the U.S. Department of Agriculture (USDA), and the National Science Foundation (NSF).

Download or read book Acoustic Emission Testing written by Christian U. Grosse and published by Springer Nature. This book was released on 2021-07-14 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to Acoustic Emission Testing and its applications to different materials like concrete, steel, ceramics, geotechnical materials, polymers, biological structures and wood. Acoustic Emission Techniques (AET) techniques have been studied in engineering for a long time. The techniques are applied more and more to practical investigations and are more and more standardized in codes. This is because the degradation of structures due to ageing urgently demand for maintenance and rehabilitation of structures in service. It results in the need for the development of advanced and efficient inspection techniques. In mechanical engineering and concerning the monitoring of machines and mechanical components, AE is a widely accepted observing deterioration in the frame of structural health monitoring. The advantages of AE like sensitivity, damage localization potential, non-intrusive nature as well as developments in signal analysis and data transmission allow applications that could not be considered decades ago. As such, AE techniques draw great attention to diagnostic applications and in material testing. This book covers all levels from the description of AE basics for AE beginners (level of a student) to sophisticated AE algorithms and applications to real large-scale structures as well as the observation of the cracking process in laboratory specimen to study fracture processes. This book has proved its worth over the past twelve years. Now in its second edition, it will be a resource that sets the standard and equips readers for the future. All chapters from the 1st edition have been updated and rewritten and eight extra chapters (e.g also regarding AE tomography, AE in plate-like structures and AE for investigations of hardening of fresh concrete) have been added.

Download or read book Measurement Uncertainty of Radiated Emissions Classic Reprint written by David A. Hill and published by Forgotten Books. This book was released on 2018-03-20 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Measurement Uncertainty of Radiated Emissions A diagram for a generic radiated emissions measurement is shown in figure 1. The equipment under test (eut) could be any electronic device, such as a digital computer, that is capable of emitting electromagnetic radiation. We include cables in figure 1 because they typically affect radiated emissions. In a formal compliance test, the measurement setup and procedure are normally specified in detail, but many other radiated emissions measurements are made without set procedures. This report covers both cases because they involve the same radiated field measurement issues and uncertainties. The measurement facility could be an outdoor facility, such as an open area test site (oats) as specified by the Federal Communications Commission (fcc) for measuring radiated emissions from computing devices or an indoor shielded facility, such as an anechoic chamber or a reverberation chamber. The receiving antenna could be any well characterized antenna. A narrowband example is a half-wavelength, tuned dipole, and broadband examples are biconical and log-periodic antennas. A typical receiver is a spectrum analyzer, and in formal compliance tests a minimum receiver bandwidth is normally specified.

Available in PDF, EPUB and Kindle. Book excerpt: Acoustic Emission (AE) techniques have been studied in civil engineering for a long time. The techniques are recently going to be more and more applied to practical applications and to be standardized in the codes. This is because the increase of aging structures and disastrous damages due to recent earthquakes urgently demand for maintenance and retrofit of civil structures in service for example. It results in the need for the development of advanced and effective inspection techniques. Thus, AE techniques draw a great attention to diagnostic applications and in material testing. The book covers all levels from the description of AE basics for AE beginners (level of a student) to sophisticated AE algorithms and applications to real large-scale structures as well as the observation of the cracking process in laboratory specimen to study fracture processes.
Download or read book Measuring Temperature in Emission Testing Micro chambers Evaluation of Potential Temperature Measurement Methods for ASTM WK40293 written by Dustin Poppendieck and published by . This book was released on 2016 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: ASTM subcommittee D22.05 on Indoor Air is working to finalize WK40293: Standard Test Method for Estimating Chemical Emissions from Spray Polyurethane Foam (SPF) Insulation Using Micro-Scale Environmental Test Chambers. One issue in WK40293 is determining the best method to accurately measure the temperature in the micro-chambers. Properly characterizing micro-chamber temperature is vital to get comparable emission data. Three methods to determining micro-chamber temperature with a thermocouple were investigated using two micro-chamber systems: 1) placing the thermocouple in the airspace of a micro-chamber, 2) taping the thermocouple to the bottom of the air filled micro-chamber, 3) placing the thermocouple in a micro-chamber filled 50 % to 75 % with water. The results show that air measurements are dependent upon the depth of the thermocouple placement, as both micro-chamber systems are stratified. Taping the thermocouple to the bottom of the micro-chamber resulted in average values that were similar to a water filled micro-chamber for one system but not the other. Data from both the air and tape methods had 1 [degrees]C to 2 [degrees]C temperature cycles in one of the systems, but not the other. The water method consistently resulted in temperature data with the smallest standard deviation. As a result of this research the authors propose new prescriptive and performance metric text for temperature measurement requirements in ASTM WK40293.
