Measuring convergence of National Accounting Standards with International Financial Reporting Standards  

Microsoft Academic Search

This paper analyses three methods for measuring the success achieved in effecting convergence between any two sets of accounting standards. We begin by reviewing a measurement method based on the concept of Euclidean distances. We then propose two better measures (involving Jaccard's coefficients and Spearman's coefficients) to assess the progress of National Accounting Standards setting bodies in converging their standards

[Spectrum analysis and measurment research on visual density of the national standard densitometer].  

PubMed

Visual density is an important index for the estimation of photographic film and visual photo. The development of biomedical image and macromolecule image needs high measurement uncertainty of visual density in spectrum characteristic. The ISO standard of visual density measurement conditions was modified in 2001. A series of equipments designed for densitometer enhance the spectral matching between the national standard densitometer and the ISO standard function. And a new measurement formula is given based on theory analysis. According to the measurement data and uncertainty analysis, the combined uncertainties are 0.001 1 (0 < D < 4.0) and 0.003 1 (4.0 < or = D < 6.0). PMID:23427559

National Energy Efficiency Evaluation, Measurement and Verification (EM&V) Standard: Scoping Study of Issues and Implementation Requirements  

SciTech Connect

This report is a scoping study that identifies issues associated with developing a national evaluation, measurement and verification (EM&V) standard for end-use, non-transportation, energy efficiency activities. The objectives of this study are to identify the scope of such a standard and define EM&V requirements and issues that will need to be addressed in a standard. To explore these issues, we provide and discuss: (1) a set of definitions applicable to an EM&V standard; (2) a literature review of existing guidelines, standards, and 'initiatives' relating to EM&V standards as well as a review of 'bottom-up' versus 'top-down' evaluation approaches; (3) a summary of EM&V related provisions of two recent federal legislative proposals (Congressman Waxman's and Markey's American Clean Energy and Security Act of 2009 and Senator Bingaman's American Clean Energy Leadership Act of 2009) that include national efficiency resource requirements; (4) an annotated list of issues that that are likely to be central to, and need to be considered when, developing a national EM&V standard; and (5) a discussion of the implications of such issues. There are three primary reasons for developing a national efficiency EM&V standard. First, some policy makers, regulators and practitioners believe that a national standard would streamline EM&V implementation, reduce costs and complexity, and improve comparability of results across jurisdictions; although there are benefits associated with each jurisdiction setting its own EM&V requirements based on their specific portfolio and evaluation budgets and objectives. Secondly, if energy efficiency is determined by the US Environmental Protection Agency to be a Best Available Control Technology (BACT) for avoiding criteria pollutant and/or greenhouse gas emissions, then a standard can be required for documenting the emission reductions resulting from efficiency actions. The third reason for a national EM&V standard is that such a standard is likely to be required as a result of future federal energy legislation that includes end-use energy efficiency, either as a stand-alone energy-efficiency resource standard (EERS) or as part of a clean energy or renewable energy standard. This study is focused primarily on this third reason and thus explores issues associated with a national EM&V standard if energy efficiency is a qualifying resource in federal clean energy legislation. Developing a national EM&V standard is likely to be a lengthy process; this study focuses on the critical first step of identifying the issues that must be addressed in a future standard. Perhaps the most fundamental of these issues is 'how good is good enough?' This has always been the fundamental issue of EM&V for energy efficiency and is a result of the counter-factual nature of efficiency. Counter-factual in that savings are not measured, but estimated to varying degrees of accuracy by comparing energy consumption after a project (program) is implemented with what is assumed to have been the consumption of energy in the absence of the project (program). Therefore, the how good is good enough question is a short version of asking how certain does one have to be of the energy savings estimate that results from EM&V activities and is that level of certainty properly balanced against the amount of effort (resources, time, money) that is utilized to obtain that level of certainty. The implication is that not only should energy efficiency investments be cost-effective, but EM&V investments should consider risk management principles and thus also balance the costs and value of information derived from EM&V (EM&V should also be cost-effective).

NAREL (National Air and Standard Environmental Laboratory) standard operating procedures for radon-222 measurement using diffusion barrier charcoal canisters  

SciTech Connect

Radon monitoring procedures for the National Air and Radiation Environment Laboratory (NAREL) are described. Radon is detected by sorption to activated charcoal, followed by detection of gamma ray emissions from the radon decay products lead-214 (295 KeV and 392 KeV) and bismuth-214 (609 KeV). The activated charcoal is held in an 8 ounce metal can, under a polyethylene diffusion barrier and a stainless steel screen, 30--50% open. The polyethylene barrier reduces water absorption by the charcoal, and improves integration over the exposure period. The proper use of the container is described, as is the counting system and calibration of the detecting system. Fabrication of reference standards and background canisters is described. Equations and sample calculations to determine radon concentrations are given. All terms in the equation are defined, and all calibration factors are calculated. The minimal detectable amounts of radon as a function of detector exposure time are calculated. 5 refs., 7 figs., 1 tab. (MHB)

Requirements relating to radon in the International Basic Safety Standards: information, measurement and national strategies.  

PubMed

The fifth edition of the International Basic Safety Standards (BSS) has recently been established as Part 3 of the General Safety Requirements of the IAEA Safety Standards Series. The BSS applies to all exposure situations and to all categories of exposure. As such, the BSS addresses both occupational exposure due to radon in workplaces and public exposure due to radon in dwellings. In workplaces, exposure due to radon is treated either as a planned exposure situation or as an existing exposure situation, depending on the circumstances. With regard to exposure due to radon in dwellings, the BSS requires that general information on radon, including information on health risks and the synergy with smoking, be made available to the public and other interested parties. Countries are also required to determine whether an action plan for controlling exposure due to radon indoors is necessary, and, if so, to establish and implement such an action plan. Guidance material, covering the establishment of reference levels, national and regional radon surveys, identification of radon prone areas, building codes for new buildings, corrective actions for existing buildings, information campaigns and programme evaluation and effectiveness is currently being developed.

The fourth workshop on Moisture Measurement and Control for Microelectronics served as a forum on moisture and/or materials reliability problems and on ways to control them or measure their extent. Twenty-two presentations are included which contain detailed information on hermeticity measurement and definition; development of standard packages for mass spectrometric calibrations; moisture interaction with various materials; and techniques that can be used to measure moisture microelectronics. It was clear from several presentations in the workshop that a very systematic approach is needed when organic materials are involved; all the variables must be identified and studied one at a time. This is the key to lot-to-lot reproducibility, materials selection, and control; hence a better reliability at the design phase will decrease the need for testing; hence the cost, thus resulting in a greater satisfaction to the customer.

The Brazilian National Standards in Acoustics  

NASA Astrophysics Data System (ADS)

The elaboration of technical standards is a difficult and expensive activity, not always necessary, since there are international standards that can be used. Therefore, the elaboration of technical standards in Brazil is, in general, linked to several programs and regulations developed in this country. Among these are the Brazilian labeling program, which intends to label domestic appliances; the approval of new car models and the annual control of the existent fleet; occupational noise control programs and the growing requirement for the accreditation of calibration and testing laboratories. In particular, in the electroacoustics area, in 1998 a Technical Committee formed of 3 Working Groups was created, which developed 11 technical standard projects relating to specific programs in the process or in the elaboration phase such as the introduction of the conformity tests for equipment used for acoustic measurements, the creation of a conformity label for audio equipment, and an intercomparision program at the national level for the calibration of audiometers. This contribution aims to show a general vision of the state of the art of Brazilian standardization as well as the several programs for which these standards will serve as support.

A Shelton Precision Interferometer Base, which is used for calibration of coordinate standards, was improved through hardware replacement, software geometry error correction, and reduction of vibration effects. Substantial increases in resolution and reliability, as well as reduction in sampling time, were achieved through hardware replacement; vibration effects were reduced substantially through modification of the machine component dampening and software routines; and the majority of the machine's geometry error was corrected through software geometry error correction. Because of these modifications, the uncertainty of coordinate standards calibrated on this device has been reduced dramatically.

Standardization of radon measurements  

SciTech Connect

Radon escaping from soil into homes appears to present the single greatest source of radiation exposure that most people will ever face. Measurement protocols for the relatively inert gas inextricably link the method of collection with the counting of the specimen. The most commonly used methods depend on the measurement of dislocation sites on plastic {alpha}-track detectors or on the adsorption of radon onto activated charcoal for subsequent counting of the {gamma}-rays produced by decay of the radon progeny. The uncertainties inherent to the radon-measurement methods used commercially in the United States are far greater than those for measurements of other environmental radionuclides. The results of this preliminary study raise doubts as to whether existing proficiency-testing programs can provide assurance that radon-measurement methods are representative of actual conditions in any dwelling. 17 refs., 1 figs., 4 tabs.

National Patterns of Risk-Standardized Mortality and Readmission for Acute Myocardial Infarction and Heart Failure: Update on Publicly Reported Outcomes Measures Based on the 2010 Release  

PubMed Central

Background Patient outcomes provide a critical perspective on quality of care. The Centers for Medicare and Medicaid Services (CMS) is publicly-reporting 30-day risk-standardized mortality rates (RSMRs) and risk-standardized readmission rates (RSRRs) for patients hospitalized with acute myocardial infarction (AMI) and heart failure (HF). We provide a national perspective on hospital performance for the 2010 release of these measures. Methods and Results The RSMRs and RSRRs are calculated from Medicare claims data for fee-for-service Medicare beneficiaries, 65 years or older, hospitalized with AMI or HF between July 1, 2006 and June 30, 2009. The rates are calculated using hierarchical logistic modeling to account for patient clustering, and are risk-adjusted for age, sex and patient comorbidities. The median RSMR for AMI was 16.0% and for HF was 10.8%. Both measures had a wide range of hospital performance with an absolute 5.2% difference between hospitals in the 5th versus 95th percentile for AMI and 5.0% for HF. The median RSRR for AMI was 19.9%, and for HF was 24.5% (3.9% range for 5–95th percentile for AMI, 6.7% for HF). Distinct regional patterns were evident for both measures and both conditions. Conclusions High RSRRs persist for AMI and HF and clinically meaningful variation exists for RSMRs and RSRRs for both conditions. Our results suggest continued opportunities for improvement in patient outcomes for HF and AMI.

National photonics skills standards for technicians  

NASA Astrophysics Data System (ADS)

Photonics is defined as the generation, manipulation, transport, detection, and use of light information and energy whose quantum unit is the photon. The range of applications of phonics extends from energy generation to detection to communication and information processing. Photonics is at the heart of today's communication systems, from the laser that generates the digital information transported along a fiber- optic cable to the detector that decodes the information. Whether the transmitted information is a phone call from across the street or across the globe, photonics brings it to you. Where your health is concerned, photonics allows physicians to do minimally invasive surgery using fiber-optic endoscopes and lasers. Researches using spectroscopy and microscopy are pushing the frontiers of biotechnology in activities as widespread as diagnosing disease and probing the mysteries of the genetic code. Advanced sensing and imaging techniques monitor the environment, gathering data on crops and forests, analyzing the ocean's currents and contents, and probing the atmosphere of pollutants. Transportation needs are being impacted by photonic sensors and laser rangefinders that will soon monitor and control the traffic on our nation's highways. In our factories, photonics provides machine vision systems that give a level of quality control human inspectors could never achieve. In manufacturing, lasers are replacing a variety of cutting, welding, and marking techniques, while imaging systems teamed with neural networks are producing intelligent robots. In short, photonics is paving our way into the new millennium. The skill standard is intended to define the knowledge and capabilities - the skills - that workers in the phonics industry need. Phonics will be one of the primary battlefields of the world economic conflict, and it is imperative that U.S. photonics technicians be skilled enough to allow the United States to remain competitive in a global marketplace. The focus of this standard is on the skills necessary for employment as a phonics technician and is not intended to be an analysis of those skills that are important for workers in all occupational areas. A comprehensive treatment of the skills necessary for all workers has been the subject of a number of studies, most notably, the work of the Secretary's Commission on the Achievement of Necessary Skills (SCANS). It is our hope at CORD that the work presented in the standard lends more detail and rational for the accomplishment of the broader skills that should be obtained by all students.

Recent fission cross section standards measurements  

SciTech Connect

The /sup 235/U(n,f) reaction is the standard by which most neutron induced fission cross sections are determined. Most of these cross sections are derived from relatively easy ratio measurements to /sup 235/U. However, the more difficult /sup 235/U(n,f) cross section measurements require the use of advanced neutron detectors for the determination of the incident neutron fluence. Examples of recent standard cross section measurements are discussed, various neutron detectors are described, and the status of the /sup 235/U(n,f) cross section standard is assessed. 23 refs., 8 figs., 4 tabs.

National Emission Standards for Hazardous Air Pollutants submittal -- 1997  

SciTech Connect

Each potential source of Nevada Test Site (NTS) emissions was characterized by one of the following methods: (1) monitoring methods and procedures previously developed at the NTS; (2) a yearly radionuclide inventory of the source, assuming that volatile radionuclide are released to the environment; (3) the measurement of tritiated water (as HTO or T{sub 2}O) concentration in liquid effluents discharged to containment ponds and assuming all the effluent evaporates over the course of the year to become an air emission; or (4) using a combination of environmental measurements and CAP88-PC to calculate emissions. The emissions for National Emission Standards for Hazardous Air Pollutants (NESHAPs) reporting are listed. They are very conservative and are used in Section 3 to calculate the EDE to the maximally exposed individual offsite. Offsite environmental surveillance data, where available, are used to confirm that calculated emissions are, indeed, conservative.

RADC/NBS (Rome Air Development Center/National Bureau of Standards) Workshop. Moisture Measurement and Control for Semiconductor Devices, 3  

NASA Astrophysics Data System (ADS)

Measurement problems in integrated circuit processing and assembly, and control of moisture in hermetically packaged semiconductor devices were examined. Thirty-four presentations are included which contain detailed information for securing hermetic packages with low moisture content. Agreement in measurement was obtained with the mass spectrometer for cerdip and metal packages at the 5000 ppmv level of moisture through the use of suitable moisture generators, a 3-volume calibrator, calibrated dewpoint hygrometers, and appropriate operational procedures. An approach is given for a reproducible and reliable transfer package. However, the increased use of organic materials in new and rapidly expanding technologies such as VLSI/VHSIC and hybrid packaging presents new and more complex challenges to accurate measurement of interior moisture.

National colloquium: developing national standards for industry, government, and academia  

NASA Astrophysics Data System (ADS)

The National Colloquium for Information Systems Security Education (the Colloquium) was established in 1997 to serve as a living body to bring government, industry, and academia together to meet the challenges of information security. All aspects of our lives and all aspects of our social, economic and political system are becoming increasingly dependent on our information and communications infrastructure. The security and assurance of our information and communications infrastructure should be a national priority. To address this, our nation needs an information-literate work force that is aware of its vulnerability, as well as a cadre of information professionals that are knowledgeable of the recognized 'best practices available in information security and information assurance, as called for in Presidential Decision Directive 63, May 22, 1998. It is the task of American higher education to provide that information- literate work force and to prepare information professions. To meet this priority, higher education must be informed of the knowledge, skills, and attitudes to be taught in the general curricula and in the information curricula of its colleges and universities. Industry and government must under their role in supporting higher education, not simply expecting higher education to be responsive and informed about information security and assurance.

IEC measurement standards for ultrasonic hydrophones and radiation force balances  

NASA Astrophysics Data System (ADS)

Acoustic output measurements of medical ultrasonic equipment are usually performed in water and using two widely established methods: ultrasonic power measurement with a radiation force balance and acoustic pressure measurement with an ultrasonic hydrophone. The International Electrotechnical Commission (IEC) has published a number of International Standards on both methods, prepared by its Technical Committee 87 ''Ultrasonics.'' These are discussed and future standardization trends are presented. The basic standard for ultrasonic power measurements is IEC 61161. It recommends using a radiation force balance and specifies the relevant technical properties and sources of uncertainty. It is currently envisaged to revise this standard and to include particular recommendations for the power range up to 20 W which have recently been worked out in an international cooperation of national metrology institutes. Hydrophone standards have continuously been developed over many years. The most recent one is IEC 62092 which extends the upper frequency limit of hydrophone standarization from 15 MHz to 40 MHz. The current trend is to reorganize all existing hydrophone standards and to find a new scheme of three parallel standards dealing with hydrophone properties, hydrophone use, and hydrophone calibration.

PubMed

To prepare anti-Brucella abortus serum used for calibrate the agglutination test follwing the national standard, 4 anti-Brucella abortus sera were obtained from 4 cows infected with Brucella abortus naturally. By potency testing, the third serum was selected. Sterility, vaccum degree, residual moisture, uniformity and stability of this standard material were tested and proved to meet the national standard. Referring to the international standard, RBT (Rose-Bengal plate agglutination test), SAT (standard tube agglutination) and CFT (complement fixation test) titers of this standard material were measured to be 1:160 "+" 1:2 400 "++" and 1:800 "++", which are identical with the collaborative assay results. International unit of the standard material is 4 000 IU/mL. PMID:21845849

National Emission Standards for Hazardous Air Pollutants submittal -- 1994  

SciTech Connect

This report focuses on air quality at the Nevada Test Site (NTS) for 1994. A general description of the effluent sources are presented. Each potential source of NTS emissions was characterized by one of the following: (1) by monitoring methods and procedures previously developed at NTS; (2) by a yearly radionuclide inventory of the source, assuming that volatile radionuclides are released to the environment; (3) by the measurement of tritiated water concentration in liquid effluents discharged to containment ponds and assuming all the effluent evaporates over the course of the year to become an air emission; or (4) by using a combination of environmental measurements and CAP88-PC to calculate emissions. Appendices A through J describe the methods used to determine the emissions from the sources. These National Emission Standards for Hazardous Air Pollutants (NESHAP) emissions are very conservative, are used to calculate the effective dose equivalent to the Maximally Exposed Individual offsite, and exceed, in some cases, those reported in DOE`s Effluent Information System (EIS). The NESHAP`s worst-case emissions that exceed the EIS reported emissions are noted. Offsite environmental surveillance data are used to confirm that calculated emissions are, indeed, conservative.

Biological measures of the standard of living.  

PubMed

When economists investigate long-term trends and socioeconomic differences in the standard of living or quality of life, they have traditionally focused on monetary measures such as gross domestic product--which has occupied center stage for over 50 years. In recent decades, however, scholars have increasingly recognized the limitations of monetary measures while seeking useful alternatives. This essay examines the unique and valuable contributions of four biological measures--life expectancy, morbidity, stature, and certain features of skeletal remains--to understand levels and changes in human well-being. People desire far more than material goods and in fact they are quite willing to trade or give up material things in return for better physical or psychological health. For most people, health is so important to their quality of life that it is useful to refer to the "biological standard of living." Biological measures may be especially valuable for historical studies and for other research circumstances where monetary measures are thin or lacking. A concluding section ruminates on the future evolution of biological approaches in measuring happiness. PMID:19771661

SUPPLEMENTARY COMPARISON: Final report on international comparisons of national standards in the field of measurements of deviations from straightness and flatness with the measurement range of deviations from straightness from 0 to 50 µm, the length of surface from 0.4 to 5 m  

NASA Astrophysics Data System (ADS)

The aim of the project was to ensure the reliability of length measurement unit transfer in the field of measurement of deviations from straightness and flatness and to confirm the claimed measurement capabilities of the national state measurement standards of Republic of Belarus, Republic of Kazakhstan and Russia. The comparison was conducted on a granite bridge of the Kazakhstan measurement standard by the measurement of its deviations from straightness using instruments which are parts of the national measurement standards of comparison participants and which they brought. The measurement results were processed, the uncertainty budgets and the confidence levels were determined, and the results were analyzed. In summary: The comparison was successfully carried out and the obtained results confirmed the measuring capabilities claimed by the participants. The reference value was calculated using arithmetical mean, weighted arithmetical mean and median of deviations from straightness of the bridge. The value 6.86 µm was chosen as the reference value with an associated expanded uncertainty of 0.52 µm. The deviation of the measurement result from the reference value of each comparison participant is, in absolute value, always smaller than or equal to the expanded uncertainty of the participant. The analysis of pair-wise equivalence shows that the estimate of difference of measurement results (systematic bias) of each possible pair of comparison participants does not exceed the expanded uncertainty of this estimate. The obtained results confirm the equivalence of participating laboratories. The results of additional comparisons which have been carried out can be presented together with those of the COOMET and BIPM ones. Main text.

Precision Standard Model measurements at the Tevatron  

SciTech Connect

The CDF and D0 collaborations at the Tevatron have produced exquisite precision measurements on high-P{sub T} physics with their large datasets of p{bar p} collisions. The top quark is being studied in great detail, and a precision of 1.1% in the measurement of its mass has been achieved. The large datasets of W and Z boson decays have allowed the most precise measurement of the W mass to date, and detailed studies of production and decay asymmetries; moreover, associated production of pairs of vector bosons have been observed and measured. The precise knowledge of top and W masses are providing decisive new input for the allowed mass range of a standard model Higgs boson, as well as for the parameter space of benchmark scenarios in supersymmetric theories.

The development of national standards for adult educators in Namibia  

NASA Astrophysics Data System (ADS)

Since gaining independence from South Africa in 1990, Namibia has placed considerable emphasis on education, including adult learning. As a means of improving the quality of adult learning, the Namibian Ministry of Education commissioned the development of national standards in 2010 to express competency requirements for adult educators. Particular attention was paid to the views of adult learners who participated through thirty focus groups. The participatory process revealed that the work of an adult educator is more complex and demanding than had previously been appreciated. The required competencies were categorised under four headings: (1) Knowledge as an adult educator, (2) Practice as an adult educator, (3) Relationships as an adult educator and (4) Ethics and professionalism as an adult educator. The Namibia Qualifications Authority, acting under its legislative mandate of setting occupational standards for occupations, jobs, posts and positions, approved the national standards in 2011.

Standardized measures for substance use stigma.  

PubMed

Despite indications that the stigma associated with substance use is high and may play a role in discouraging treatment participation, there is limited research in this area and only a few psychometrically sound measures of substance use stigma exist. The purpose of this study was to formulate and evaluate the psychometric properties of three substance use stigma measures. College students (N=565) completed three measures of substance use stigma that were modified from three established measures of mental illness stigma. Two of the three modified measures (Social Distance Scale for Substance Users and Affect Scale for Substance Users) emerged as having acceptable psychometric properties, whereas one modified measure (Dangerousness Scale for Substance Users) had inadequate psychometric properties. In regard to sex differences, women had significantly higher substance use stigma on the two psychometrically sound measures (p<.01). Perhaps, with standardized measures, there can be greater progress towards better understanding the mechanisms leading to high levels of substance use stigma and ultimately address failures to seek out treatment due to stigma.

Intrathoracic pressure measurement in cattle: standardized procedure.  

PubMed Central

A procedure to standardize the position of an esophageal catheter (eso-cat) tip, used to measure intrathoracic pressure, was tested in ten healthy Dutch Friesians. The cattle were in normal condition with body weights (BW) between 52 and 670 kg and thoracic perimeters (TP) between 80 and 210 cm. The position of the neck and head was standardized. The eso-cat was introduced via the nose into the thoracic portion of the esophagus. The distance between the nares and the eso-cat tip (Lcat), which was positioned between the crossing point with the aorta and the caudal mediastinal lymph nodes, was measured for each animal. The regression equation, calculated between the Lcat and the BW and TP was, respectively: Lcat (cm) = 65 + 0.115 x BW (kg) (r2 = 0.99) and Lcat (cm) = 22 + 0.535 x TP (cm) (r2 = 0.97). The corresponding residual standard deviations were respectively 2.52 and 4.37 cm. The multiple and curvi-linear regression equation did not give a significantly better fit of the data.

[Standardized new method for measuring vibration perception].  

PubMed

The examination of the vibration perception is one of the basic measurements applied in the evaluation of the peripheral neuropathies in hand-arm vibration syndrome (HAVS) The detailed guidelines on how this kind of examinations should be performed, presented in the 1998 ISO standard, differ substantially from those currently binding in Poland. The aim of this study was to standardize the method of vibration perception measurements, taking account of the parameters consistent with the ISO recommendations, such as algorithm (stimulus presentation method), vibration frequency, the size and contact force of vibrating probe, as well as the comparison of the results obtained by means of both methods (ISO-recommended method and standard Polish method). It was found that the algorithm change (ascending method replaced by Bekesy's technique, recommended by ISO) did not affect the of the vibration perception thresholds values within the wide range of frequencies (32-500 Hz), whereas the decreased size of probe, pressed with smaller contact force, resulted in significantly higher values of perception thresholds within the frequency range of 125-400 Hz. The comparison of the outcomes of the ISO-recommended and Polish standard methods revealed that the perception thresholds did not differ at the frequency of 125 Hz, but at the frequencies of 250 and 400 Hz, the ISO-recommended method produced higher values. Moreover, at the frequencies ranging from 125 to 400 Hz, the results of the perception threshold measurements, taken several times in the same persons (intrasubject variability) by means of both methods, were more scattered. It was revealed that the measurements at the frequency range of 4-125 Hz should be included in the vibration perception examinations, and the certification of the ability to work in the conditions of exposure to hand-arm vibration should be based on their results. It is also essential that in the standard examination, a smaller vibratory probe (phi = 5 mm) and lighter contact force (0.1 N) than those currently used, should be applied. PMID:11828844

The importance and necessity for a fully developed and implemented National Incident Management System (NIMS) has been demonstrated in recent years by the impact of national events such as Hurricane Katrina in 2005. Throughout the history of emergency response to major disasters, especially when multiple response organizations are involved, there have been systemic problems in the consistency and uniformity of response operations. Identifying national standards that support the development and implementation of NIMS is key to helping solve these systemic problems. The NIMS seeks to provide uniformity and consistency for incident management by using common terminology and protocols that will enable responders to coordinate their efforts to ensure an efficient response.

This paper describes a set of tests used to determine Phasor Measurement Unit (PMU) measurement characteristics under steady state and dynamic conditions. The methodology is repeatable, comparable among test facilities, and can be performed at any facility with commonly available relay and standard test equipment. The methodology is based upon using test signals that are mathematically generated from a signal model and played into the PMU with precise GPS synchronization. Timing flags included with the test signal provide correlate the test signals and the PMU output. This allows accurate comparison of the phasor model with the value estimated by the PMU for accurate performance analysis. The timing flags also facilitate programmed plot and report generation.

Radiation-based quantitative bioimaging at the national institute of standards and technology  

PubMed Central

Building on a long history of providing physical measurements and standards for medical X rays and nuclear medicine radionuclides, the laboratory has expanded its focus to better support the extensive use of medical physics in the United States today, providing confidence in key results needed for drug and device development and marketing, therapy planning and efficacy and disease screening. In particular, to support more quantitative medical imaging, this laboratory has implemented a program to provide key measurement infrastructure to support radiation-based imaging through developing standard, benchmark phantoms, which contain radioactive sources calibrated to national measurement standards, to allow more quantitative imaging through traceable instrument calibration for clinical trials or patient management. Working closely with colleagues at the National Institutes of Health, Rensselaer Polytechnic Institute, the Food and Drug Administration and Cornell University, this laboratory has taken the initial steps in developing phantoms, and the protocols to use them, for more accurate calibration of positron emission tomography (PET) or single-photon emission computed tomography (SPECT) cameras, including recently standardizing 68Ge. X-ray measurements of the laboratory's recently developed small, resilient and inexpensive length standard phantom have shown the potential usefulness of such a “pocket” phantom for patient-based calibration of computed tomography (alone or with PET) systems. The ability to calibrate diagnostic imaging tools in a way that is traceable to national standards will lead to a more quantitative approach; both physician and patient benefit from increased accuracy in treatment planning, as well as increased safety for the patient.

National Emission Standards for Hazardous Air Pollutants Calendar Year 2005  

SciTech Connect

The Nevada Test Site (NTS) is operated by the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office (NNSA/NSO). From 1951 through 1992, the NTS was operated as the nation’s site for nuclear weapons testing. The release of man-made radionuclides from the NTS as a result of testing activities has been monitored since the first decade of atmospheric testing. After 1962, when nuclear tests were conducted only underground, the radiation exposure to the public surrounding the NTS was greatly reduced. After the 1992 moratorium on nuclear testing, radiation monitoring on the NTS focused on detecting airborne radionuclides that are resuspended into the air (e.g., by winds, dust-devils) along with historically-contaminated soils on the NTS. To protect the public from harmful levels of man-made radiation, the Clean Air Act, National Emission Standards for Hazardous Air Pollutants (NESHAP) (40 Code of Federal Regulations 61 Subpart H) limits the release of radioactivity from a U. S. Department of Energy (DOE) facility (e.g., the NTS) to 10 millirem per year (mrem/yr) effective dose equivalent (EDE) to any member of the public. This is the dose limit established for someone living off of the NTS for inhaling radioactive particles that may be carried by wind off of the NTS. This limit assumes that members of the public surrounding the NTS may also inhale “background levels” or radioactive particles unrelated to NTS activities that come from naturally-occurring elements in the environment (e.g., radon gas from the earth or natural building materials) or from other man-made sources (e.g., cigarette smoke). The U. S. Environmental Protection Agency (EPA) requires DOE facilities (e.g., the NTS) to demonstrate compliance with the NESHAP dose limit by annually estimating the dose to a hypothetical member of the public, referred to as the maximally exposed individual (MEI), or the member of the public who resides within an 80-kilometer (50-mile) radius of the facility who would experience the highest annual dose. This dose to a hypothetical person living close to the NTS cannot exceed 10 mrem/yr. C.1 This report has been produced annually for the EPA Region IX, and for the state of Nevada since 1992 and documents that the estimated EDE to the MEI has been, and continues to be, well below the NESHAP dose limit. The report format and level of technical detail has been dictated by the EPA and DOE Headquarters over the years. It is read and evaluated for NESHAP compliance by federal and state regulators. Each section and appendix presents technical information (e.g., NTS emission source estimates, onsite air sampling data, air transport model input parameters, dose calculation methodology, etc.), which supports the annual dose assessment conclusions. In 2005, as in all previous years for which this report has been produced, the estimated dose to the public from inhalation of radiological emissions from current and past NTS activities is shown to be well below the 10 mrem/yr dose limit. This was demonstrated by air sampling data collected onsite at each of six EPA-approved “critical receptor” stations on the NTS. The sum of measured EDEs from the four stations at the NTS boundaries is 2.5 mrem/yr. This dose is 25 percent of the allowed NESHAP dose limit. Because the nearest member of the public resides approximately 20 kilometers (12 miles) from the NTS boundary, this individual receives only a small fraction of this dose. NESHAP compliance does not require DOE facilities to estimate annual inhalation dose from non-DOE activities. Therefore, this report does not estimate public radiation doses from any other sources or activities (e.g., naturally-occurring radon, global fallout).

US National Large-scale City Orthoimage Standard Initiative  

USGS Publications Warehouse

The early procedures and algorithms for National digital orthophoto generation in National Digital Orthophoto Program (NDOP) were based on earlier USGS mapping operations, such as field control, aerotriangulation (derived in the early 1920's), the quarter-quadrangle-centered (3.75 minutes of longitude and latitude in geographic extent), 1:40,000 aerial photographs, and 2.5 D digital elevation models. However, large-scale city orthophotos using early procedures have disclosed many shortcomings, e.g., ghost image, occlusion, shadow. Thus, to provide the technical base (algorithms, procedure) and experience needed for city large-scale digital orthophoto creation is essential for the near future national large-scale digital orthophoto deployment and the revision of the Standards for National Large-scale City Digital Orthophoto in National Digital Orthophoto Program (NDOP). This paper will report our initial research results as follows: (1) High-precision 3D city DSM generation through LIDAR data processing, (2) Spatial objects/features extraction through surface material information and high-accuracy 3D DSM data, (3) 3D city model development, (4) Algorithm development for generation of DTM-based orthophoto, and DBM-based orthophoto, (5) True orthophoto generation by merging DBM-based orthophoto and DTM-based orthophoto, and (6) Automatic mosaic by optimizing and combining imagery from many perspectives.

Recommendations for a commercial vehicle to roadway communications national standard  

SciTech Connect

This is the final report by the Lawrence Livermore National Laboratory (LLNL). Based on the authors studies of the Electronic Toll and Traffic Management (ETTM) industry, they make recommendations for a possible future national standard for short range Vehicle-to-Roadway Communications (VRC) for Commercial Vehicle Operations (CVO). Of primary interest to the Federal Highway Administration are Mainline Automated Clearance Systems (MACS). In such a system, CVs would exchange data with weigh-stations and ports of entry at highway speeds using wireless Radio Frequency (RF) techniques and to enable automated clearance. The CV would carry a transponder (or tag) and transmit electronic credentials, safety data, in-transit data, etc. on command from a roadside transceiver (or reader) upstream from the weigh-station or port of entry. Computer processing of this data, plus the weigh-in-motion reading and historical information, would be used to decide whether to direct the truck to stop for manual clearance or proceed.

Substantive inference from cross-national studies have important implications for theory (e.g., because they reveal insights into generalizability and boundary conditions) and managerial practice (e.g., because they offer guidelines to MNC managers). However, few empirical studies attend to measurement issues involved in cross-national research, and still fewer recognize the risk of inferential errors that are likely to occur by overlooking measurement

Accelerator-based Neutron Fluence Standard of the National Metrology Institute of Japan  

SciTech Connect

We report the present status of the national standard on accelerator-based fast neutron fluences in Japan. Monoenergetic neutron fluence standards have been established at 144 keV, 565 keV, 5.0 MeV and 8.0 MeV by using a Van de Graaff accelerator and at 2.5 MeV and 14.8 MeV by using a Cockcroft Walton accelerator. These standards are prepared to measure the detection efficiency and the energy response of neutron sensitive devices, such as personal dosimeters and survey meters. Neutron production and absolute fluence measurement for these energies are described. We are developing a new standard in the energy region of a few tens of keV, which is also introduced here as well as our future plans.

Evaluating a Proposed 20% National Renewable Portfolio Standard  

SciTech Connect

This paper provides a preliminary analysis of the impacts of a proposed 20% national renewable portfolio standard (RPS) by 2021, which has been advanced in the U.S. Congress by Senator Jeff Bingaman of New Mexico. The paper was prepared before the America Recovery and Reinvestment Act was signed into law by President Barack Obama on February 17, 2009, and thus does not consider important changes in renewable energy (RE) policy that need to be addressed in follow-on analysis. We use NREL's Regional Energy Deployment System (ReEDS) model to evaluate the impacts of the RPS requirements on the energy sector and consider design issues associated with renewable energy certificate (REC) trading markets.

Urban-aerosol acids: Analysis of National Institute of Standards and Technology Standard Reference Material 1649  

SciTech Connect

Urban air particulate matter, collected from Washington, D.C. and certified by the National Institute of Standards and Technology (NIST) as Standard Reference Material 1649, was extracted and fractionated into acid, base and neutral fractions. Each fraction was tested for biological activity using a microbial mutagenesis assay system. The organic acid fraction showed unexpectedly high mutagenic activity, and was subjected to chemical characterization studies. Following derivatization, analysis by GC/MS showed the presence of fatty acids, aromatic acids (including phenolic compounds), and a significant number of compounds that could not be identified from mass spectral compendia. Spectroscopic and elemental analysis data supported the characterization of the fraction as predominantly aromatic. Mass spectra from both GC/MS and direct probe analysis showed the presence of a chlorinated substance, subsequently identified as the fungicide Dichlorophen. The compound was shown to comprise over 50 percent of the mass of the organic acid fraction. A reference standard of Dichlorophen was not mutagenic. The presence of the fungicide in the NIST certified urban aerosol is, in all probability due to artifactual processes. Attempts to concentrate the observed mutagenic activity by preparative chromatography and acid/base partition experiments were not successful.

National Incident Management System (NIMS) Standards Review Panel Workshop Summary Report  

SciTech Connect

The importance and need for full compliant implementation of NIMS nationwide was clearly demonstrated during the Hurricane Katrina event, which was clearly expressed in Secretary Chertoff's October 4, 2005 letter addressed to the State's governors. It states, ''Hurricane Katrina was a stark reminder of how critical it is for our nation to approach incident management in a coordinated, consistent, and efficient manner. We must be able to come together, at all levels of government, to prevent, prepare for, respond to, and recover from any emergency or disaster. Our operations must be seamless and based on common incident management doctrine, because the challenges we face as a nation are far greater than capabilities of any one jurisdiction.'' The NIMS is a system/architecture for organizing response on a ''national'' level. It incorporations ICS as a main component of that structure (i.e., it institutionalizes ICS in NIMS). In a paper published on the NIMS Website, the following statements were made: ''NIMS represents a core set of doctrine, principles, terminology, and organizational processes to enable effective, efficient and collaborative incident management at all levels. To provide the framework for interoperability and compatibility, the NIMS is based on a balance between flexibility and standardization.'' Thus the NIC is challenged with the need to adopt quality SDO generated standards to support NIMS compliance, but in doing so maintain the flexibility necessary so that response operations can be tailored for the specific jurisdictional and geographical needs across the nation. In support of this large and complex challenge facing the NIC, the Pacific Northwest National Laboratory (PNNL) was asked to provide technical support to the NIC, through their DHS Science and Technology ? Standards Portfolio Contract, to help identify, review, and develop key standards for NIMS compliance. Upon examining the challenge, the following general process appears to be a reasonable approach for identifying and establishing existing standards that would be applicable to NIMS compliance. The suggested generalized steps to establishing existing SDO generated standards for NIMS compliance are: (1) establish search criteria from the NIMS and its support documents, (2) search SDO databases to identify key existing nationally and/or internationally recognized standards that have potential application to NIMS compliance needs, (3) review the identified standards against the specific component needs of the NIMS, (4) identify the pertinent aspects/components of those identified standards that clearly address specific NIMS compliance needs, (5) establish a process to adopt the pertinent standards, which includes the generation of formalized FEMA Guidance that identifies the specific NIMS component compliance needs addressed in the respective standard, (6) develop performance criteria for which to measure compliance with the identified NIMS components addressed by the respective adopted standard, and (7) adopt the standard, publish the guidance and performance criteria, and incorporate it into routine FEMA/NIC NIMS management operations. This review process will also help identify real gaps in standards for which new NIMS specific standards should be developed. To jump start this process and hopefully identify some key ''low hanging fruit'' standards the NIC could use to begin such a process, a panel of first-responder experts (familiar with the current standards of common use in the first-responder community) from various response disciplines was formed and a workshop held. The workshop included a pre-workshop information gathering process. This report discusses the workshop and its findings in detail.

New National Science Standards and Astronomy: An Update on the National Scene  

NASA Astrophysics Data System (ADS)

In the summer of 2009, the National Academy of Science (NAS) began the process of collecting input on the development of the next-generation of national science education standards and frameworks for K-12 schools. We were asked to provide input related to the science disciplines' perspectives on core ideas around which the standards would be designed. This paper is an abbreviated summary of our work commissioned by the NAS, providing an interpretation of "core ideas" as those few notions that have broad explanatory and predictive power, proposes a possible set of criteria for their identification, and suggests some implications to a standards development process. The broad notion of a core idea in science is proposed as one of a brief, yet cohesive, set of statements that taken together have deep explanatory and predictive power describing observed phenomena in the natural world. The characteristic of a core idea is that it helps learners make sense of considerable information and confusing claims. We propose that there are only a few core ideas relevant to a scientifically literate citizenship, and they are highly intertwined with one another. Additionally, we propose that our collected observations of K-12 teachers and classrooms have implications for the EPO and Astronomy Education Research communities. EPO products need to be explicitly tied to and constrained by these core ideas, and they need to explicitly link content and cross-cutting ideas. Future astronomy education research should most likely turn its attention to small-medium scale studies that focus on cognitive mechanisms.

Standardization and analytical goals for glycated hemoglobin measurement.  

PubMed

Abstract Glycated hemoglobin (HbA1c) plays a key role in diagnosing diabetes and monitoring the glycemic state. To guarantee the reliability of its measurement at the global level, the IFCC has defined a reference measurement system, based on the definition of the measurand as hemoglobin molecules having a special hexapeptide in common, which is the stable adduct of glucose to the N-terminal valine of the hemoglobin ?-chain. In addition to the traceability of HbA1c results to the reference system, the establishment of analytical goals to make HbA1c measurements clinically reliable becomes crucial. However, allowable goals will depend on the assay specificity (i.e., selectivity) and, consequently, on units in which HbA1c results are expressed [mmol/mol for IFCC-aligned systems or % for National Glycohemoglobin Standardization Program (NGSP) converted numbers]. In this regard, analytical goals derived from biological variability studies in which the determination of HbA1c has been carried out by an assay providing the same selectivity for the measurand as defined by the IFCC are recommended. Only these targets should be used for evaluating the performance of commercial assays traceable to the IFCC system and of clinical laboratories using them through appropriately structured quality assessment schemes. Analytical systems following different calibration hierarchies (e.g., the NGSP-aligned assays) will require different analytical goals, possibly derived from clinical outcome data. PMID:23729573

NIST bullet signature measurement system for RM (Reference Material) 8240 standard bullets.  

PubMed

A bullet signature measurement system based on a stylus instrument was developed at the National Institute of Standards and Technology (NIST) for the signature measurements of NIST RM (Reference Material) 8240 standard bullets. The standard bullets are developed as a reference standard for bullet signature measurements and are aimed to support the recently established National Integrated Ballistics Information Network (NIBIN) by the Bureau of Alcohol, Tobacco and Firearms (ATF) and the Federal Bureau of Investigation (FBI). The RM bullets are designed as both a virtual and a physical bullet signature standard. The virtual standard is a set of six digitized bullet signatures originally profiled from six master bullets fired at ATF and FBI using six different guns. By using the virtual signature standard to control the tool path on a numerically controlled diamond turning machine at NIST, 40 RM bullets were produced. In this paper, a comparison parameter and an algorithm using auto-and cross-correlation functions are described for qualifying the bullet signature differences between the RM bullets and the virtual bullet signature standard. When two compared signatures are exactly the same (point by point), their cross-correlation function (CCF) value will be equal to 100%. The measurement system setup, measurement program, and initial measurement results are discussed. Initial measurement results for the 40 standard bullets, each measured at six land impressions, show that the CCF values for the 240 signature measurements are higher than 95%, with most of them even higher than 99%. These results demonstrate the high reproducibility for both the manufacturing process and the measurement system for the NIST RM 8240 standard bullets. PMID:15317178

Standardization of Laser Methods and Techniques for Vibration Measurements and Calibrations  

SciTech Connect

The realization and dissemination of the SI units of motion quantities (vibration and shock) have been based on laser interferometer methods specified in international documentary standards. New and refined laser methods and techniques developed by national metrology institutes and by leading manufacturers in the past two decades have been swiftly specified as standard methods for inclusion into in the series ISO 16063 of international documentary standards. A survey of ISO Standards for the calibration of vibration and shock transducers demonstrates the extended ranges and improved accuracy (measurement uncertainty) of laser methods and techniques for vibration and shock measurements and calibrations. The first standard for the calibration of laser vibrometers by laser interferometry or by a reference accelerometer calibrated by laser interferometry (ISO 16063-41) is on the stage of a Draft International Standard (DIS) and may be issued by the end of 2010. The standard methods with refined techniques proved to achieve wider measurement ranges and smaller measurement uncertainties than that specified in the ISO Standards. The applicability of different standardized interferometer methods to vibrations at high frequencies was recently demonstrated up to 347 kHz (acceleration amplitudes up to 350 km/s{sup 2}). The relative deviations between the amplitude measurement results of the different interferometer methods that were applied simultaneously, differed by less than 1% in all cases.

Standards for organic contaminant thickness measurement by the ellipsometer  

SciTech Connect

No film thickness standards have been established for the ellipsometer that can be used for determining the thickness of organic contaminants on electrical components. Thickness measurement of organic contamination on a surface is dependent on the refractive index of the film; knowledge of the refractive index of the film is required before thickness measurements can be made. Silicon oxide has a refractive index equivalent to most organic materials. Silicon oxide, therefore, can be used for developing thickness standards for use in ellipsometer measurement of organic film contamination. A film thickness standard curve was established by correlating known silicon oxide thicknesses with their corresponding phase change (delta, an optical constant of the surface). Thickness standards up to 2700 A were established.

Use of internal standards for the measurement of reaction entropies  

SciTech Connect

A simple method is reported for measuring the entropy changes associated with a single redox couple, ..delta..S/sup 0/. This method, which eliminates the need for nonisothermal cell measurements, involves recording the reduction potential of an internal redox couple, E/sup f//sub sam/, versus the reduction potential of an internal standard, E/sup f//sub std/, at a variety of temperatures in a single compartment thermostated cell. Ferrocene serves as a standard for measurements in nonaqueous systems and ruthenium hexaamine in aqueous solutions. Measurements of the entropy values for Co(phen)/sub 3//sup 2 +/, where phen = 1,10-phenanthroline in water and for Co(Cp)/sub 2/ (cobaltocene) in acetonitrile are presented as illustrations of the applicability of the method. Values of the entropy changes obtained by this internal standard method can be used to obtain thermodynamic parameters associated with electron-transfer cross reactions. 15 references, 1 figure, 1 table.

National Emission Standards for Hazardous Air Pollutants Calendar Year 2006  

SciTech Connect

The Nevada Test Site (NTS) is operated by the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office (NNSA/NSO). From 1951 through 1992, the NTS was operated as the nation's site for nuclear weapons testing. The release of man-made radionuclides from the NTS as a result of testing activities has been monitored since the first decade of atmospheric testing. After 1962, when nuclear tests were conducted only underground, the radiation exposure to the public surrounding the NTS was greatly reduced. After the 1992 moratorium on nuclear testing, radiation monitoring on the NTS focused on detecting airborne radionuclides which come from historically-contaminated soils resuspended into the air (e.g., by winds) and tritium-contaminated soil moisture emitted to the air from soils through evapotranspiration.

Nursing student compliance to standards for blood pressure measurement.  

PubMed

In conclusion, no individual student complied with every step of the recommended procedure. In fact, 95% failed to comply with some specific steps that are unique to the AHA standards and that experts consider critical to accurate blood pressure measurement. Response to the questionnaire revealed that factors of logistics and attitudes of others influence student compliance or at least make the situation less conducive to adhering to the AHA standards. An additional interesting finding from the questionnaire was that while students may not have complied entirely with the AHA standards, they believed the procedure to be reasonable and to provide an accurate reading of blood pressure.

Applicability of ISO standard methods to vibration measurements at high frequencies and high accelerations  

NASA Astrophysics Data System (ADS)

New and revised laser methods and techniques developed by national metrology institutes and by leading manufacturers in the past two decades have been swiftly specified as standard methods in the ISO 16063 series of international document standards. The first international standard for the calibration of laser vibrometers, ISO 16063-41:2011, specifies the instrumentation and procedures for performing primary and secondary calibrations of rectilinear laser vibrometers in "typical" ranges of frequency (0,4 Hz to 50 kHz) and other conditions, with "typical attainable uncertainties" (0,25% to 5% for different specified conditions). This allows the specified standard methods to apply with refined techniques and procedures achieving even wider measurement ranges and smaller measurement uncertainties than that specified in the ISO standard. Recent theoretical and experimental investigations demonstrate the applicability of the standardized interferometric methods up to frequencies considerably higher than 50 kHz if measurable vibration amplitudes are generated. Sinusoidal vibration was generated by a piezoelectric actuator at frequencies between 63 kHz and 347 kHz and the displacement was measured by different interferometric standard methods applied simultaneously. Their results differed by less than 1% from each other. From the analysis of the results it is expected that frequencies up to 500 kHz are achievable.

The development of national quality performance standards for disposable absorbent products for adult incontinence.  

PubMed

Disposable absorbent products are widely used in inpatient care settings and in the community to manage adult urinary and fecal incontinence, but few product standards exist to help guide their production or optimal use. Increasing costs and reduced revenues have caused a number of states to evaluate absorbent product use among persons who receive care at home with the assistance of the Medicaid Waiver Program, further increasing concerns about the lack of product performance standards. To address these issues, the National Association For Continence (NAFC) formed a council of experts and key stakeholders with the objective of establishing national, independent quality performance standards for disposable absorbent products provided by states to Waiver Program recipients. The Council consisted of representatives from five purposefully selected states, technical directors from six nonwoven product manufacturers, an officer of the nonwoven manufactures trade association, a delegate from an academic nursing program and professional societies, a family caregiver, and a patient representative. Following a consensus method and guidelines for use, nine specific recommendations were developed, posted for public comment, and further refined. Final recommendations for product performance assessment include: rewet rate (a measure of a product's ability to withstand multiple incontinent episodes between changes), rate of acquisition (a measure of the speed at which urine is drawn away from the skin by a product, product retention capacity (a measure of a product's capacity to hold fluid without rewetting the skin), sizing options, absorbency levels, product safety, closure technology, breathable zones (a measure of the air permeability across a textile-like fabric at a controlled differential pressure), and elasticity. The Council also set values for and recommended four quantifiable parameters, and the testing methodology associated with each, to help consumers and states evaluate absorbent products (medium adult size): Maximum Rewet Rate: <1.0-2.0 g for briefs and <0.5-1.0 g for underwear; Maximum Rate of Acquisition: <50-60 seconds for briefs and <35-45 seconds for underwear; Minimum Retention Capacity: >250 g for standard briefs or underwear and >400 g for premium briefs or underwear; and Breathability of Zones: Minimum of >100 cubic feet per minute. As these recommendations are implemented, research is needed to evaluate the impact on both cost and quality of care for further refinement and modifications, particularly as technology and knowledge is advanced.

Correlation of topography measurements of NIST SRM 2460 standard bullets by four techniques  

NASA Astrophysics Data System (ADS)

Three optical instruments including an interferometric microscope, a Nipkow disc confocal microscope and a laser scanning confocal microscope and a stylus instrument are used for the measurements of bullet profile signatures of a National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) 2460 standard bullet. The two-dimensional profile signatures are compared with the virtual bullet standard signature established by the same stylus instrument. The bullet signature differences are quantified by the maximum cross-correlation function CCFmax. If the compared signatures were exactly the same, CCFmax would be 100%. Comparison results show close agreement among the four techniques for bullet profile signature measurements. The average CCFmax values are higher than 90%. This supports the possibility of using surface topography techniques for ballistic identifications as an alternative to the current technology based on image comparisons.

The Nevada Test Site (NTS) is operated by the U.S. Department of Energy Nevada Operations Office (DOE/NV) as the site for nuclear weapons testing, now limited to readiness activities and experiments in support of the national Stockpile Stewardship Management Program. It is located in Nye County, Nevada, with the southeast corner about 105 km (65 mi) northwest of Las Vegas, Nevada. The NTS covers about 3,500 km2 (1,350 mi2), an area larger than Rhode Island. Its size is about 46 to 56 km (28 to 35 mi) east to west and from 64 to 88 km (40 to 55 mi)north to south. The NTS is surrounded, except on the south side, by public exclusion areas (Nellis Air Force Range) that provide another 24 to 104 km (15 to 65 mi) between the NTS and public lands. The NTS is characterized by desert valley and Great Basin mountain topography, with a climate, flora, and fauna typical of the southwest deserts. Surface waters are scarce on the NTS and there is great depth to slow-moving groundwater.

SciTech Connect

The Nevada Test Site (NTS) is operated by the US Department of Energy's Nevada Operations Office (DOE/NV) as the site for nuclear weapons testing, now limited to readiness activities and experiments in support of the national Stockpile Stewardship Management Program. It is located in Nye County, Nevada, with the southeast corner about 105 km (65 mi) northwest of Las Vegas, Nevada. The NTS covers about 3,561 km{sup 2} (1,375 mi{sup 2}), an area larger than Rhode Island. Its size is about 46 to 56 km (28 to 35 mi) east to west and from 64 to 88 km (40 to 55 mi) north to south. The NTS is surrounded, except on the south side, by public exclusion areas (Nellis Air Force Range [NAFR]) that provide another 24 to 104 km (15 to 65 mi) between the NTS and public lands. The NTS is characterized by desert valley and Great Basin mountain topography, with a climate, flora, and fauna typical of the southwest deserts. Population density within 150 km (93 mi) of the NTS is only about 0.2 persons per square kilometer, excluding the Las Vegas area. Restricted access, low population density in the surrounding area, and extended wind transport times are advantageous factors for the activities conducted at the NTS. Surface waters are scarce on the NTS and there is great depth to slow-moving groundwater.

Creation of the ? angle standard for the flat angle measurements  

NASA Astrophysics Data System (ADS)

Angle measurements are based mainly on multiangle prisms - polygons with autocollimators, rotary encoders fo high accuracy and circular scales as the standards of the flat angle. Traceability of angle measurements is based on the standard of the plane angle - prism (polygon) calibrated at an appropriate accuracy. Some metrological institutions have established their special test benches (comparators) equipped with circular scales or rotary encoders of high accuracy and polygons with autocollimators for angle calibration purposes. Nevertheless, the standard (etalon) of plane angle - polygon has many restrictions for the transfer of angle unit - radian (rad) and other units of angle. It depends on the number of angles formed by the flat sides of the polygon that is restricted by technological and metrological difficulties related to the production and accuracy determination of the polygon. A possibility to create the standard of the angle equal to ? rad or half the circle or the full angle is proposed. It can be created by the circular scale with the rotation axis of very high accuracy and two precision reading instruments, usually, photoelectric microscopes (PM), placed on the opposite sides of the circular scale using the special alignment steps. A great variety of angle units and values can be measured and its traceability ensured by applying the third PM on the scale. Calibration of the circular scale itself and other scale or rotary encoder as well is possible using the proposed method with an implementation of ? rad as the primary standard angle. The method proposed enables to assure a traceability of angle measurements at every laboratory having appropriate environment and reading instruments of appropriate accuracy together with a rotary table with the rotation axis of high accuracy - rotation trajectory (runout) being in the range of 0.05 ?m. Short information about the multipurpose angle measurement test bench developed is presented.

The Nevada Test Site (NTS) is operated by the U.S. Department of Energy (DOE), National Nuclear Security Administration Nevada Operations Office (NNSA/NV) as the site for nuclear weapons testing, now limited to readiness activities, experiments in support of the national Stockpile Stewardship Program, and the activities listed below. Located in Nye County, Nevada, the site's southeast corner is about 88 km (55 mi) northwest of the major population center, Las Vegas, Nevada. The NTS covers about 3,561 km2 (1,375 mi2), an area larger than Rhode Island. Its size is 46 to 56 km (28 to 35 mi) east to west and from 64 to 88 km (40 to 55 mi) north to south. The NTS is surrounded, except on the south side, by public exclusion areas (Nellis Air Force Range [NAFR]) that provide another 24 to 104 km (15 to 65 mi) between the NTS and public lands (Figure 1.0). The NTS is characterized by desert valley and Great Basin mountain topography, with a climate, flora, and fauna typical of the southwest deserts. Population density within 150 km (93 mi) of the NTS is only about 0.2 persons per square kilometer, excluding the Las Vegas area. Restricted access, low population density in the surrounding area, and extended wind transport times are advantageous factors for the activities conducted at the NTS. Surface waters are scarce on the NTS, and slow-moving groundwater is present hundreds to thousands of feet below the land surface. The sources of radionuclides include current and previous activities conducted on the NTS (Figure 2.0). The NTS was the primary location for testing of nuclear explosives in the Continental U.S. between 1951 and 1992. Historical testing above or at ground surface has included (1) atmospheric testing in the 1950s and early 1960s, (2) earth-cratering experiments, and (3) open-air nuclear reactor and rocket engine testing. Since the mid-1950s, testing of nuclear explosive devices has occurred underground in drilled vertical holes or in mined tunnels (DOE 1996a). No such tests have been conducted since September 23, 1992 (DOE 2000). Limited non-nuclear testing includes spills of hazardous materials at the Hazardous Materials Spill Center, private technology development, aerospace and demilitarization activities, and site remediating activities. Processing of radioactive materials is limited to laboratory analyses, and handling is restricted to transport, storage, and assembly of nuclear explosive devices and operation of radioactive waste management sites (RWMSs) for low-level radioactive and mixed waste (DOE 1996a). Monitoring and evaluation of the various activities conducted onsite indicate that the potential sources of offsite radiation exposure in CY 2001 were releases from (1) evaporation of tritiated water (HTO) from containment ponds that receive drainage water from E Tunnel in Area 12 and from discharges of two wells (Well U-3cn PS No. 2 and Well ER-20-5 No.3) into lined ponds, (2) onsite radio analytical laboratories, (3) the Area 5 RWMS (RWMS-5) facility, and (4) diffuse sources of tritium and re- suspension of plutonium and americium. The following sections present a general description of the present sources on the NTS and at the North Las Vegas Facility.

Standard target sets for field sensor performance measurements  

NASA Astrophysics Data System (ADS)

The US Army Night Vision and Electronic Sensors Directorate (NVESD) Modeling and Simulation Division develops sensors models (FLIR 92, NV Therm, NV Therm IP) that predict the comparative performance of electro-optical sensors. The NVESD modeling branch developed a 12-vehicle, 12-aspect target signature set in 1998 with a known cycle criteria. It will be referred to as the 12-target set. This 12-target set has and will continue to be the modeling "gold standard" for laboratory human perception experiments supporting sensor performance modeling, and has been employed in dozens of published experiments. The 12-target set is, however, too costly for most acquisition field tests and evaluations. The authors developed an 8-vehicle 3-aspect target set, referred to as the 8- target set, and measured its discrimination task difficulty, (N50 and V50). Target identification (ID) range performance predictions for several sensors were made based on those V50/N50 values. A field collection of the 8-target set using those sensors provided imagery for a human perception study. The human perception study found excellent agreement between predicted and measured range performance. The goal of this development is to create a "silver standard" target set that is as dependable in measuring sensor performance as the "gold standard", and is affordable for Milestone A and other field trials.

Data format standard for sharing light source measurements  

NASA Astrophysics Data System (ADS)

Optical design requires accurate characterization of light sources for computer aided design (CAD) software. Various methods have been used to model sources, from accurate physical models to measurement of light output. It has become common practice for designers to include measured source data for design simulations. Typically, a measured source will contain rays which sample the output distribution of the source. The ray data must then be exported to various formats suitable for import into optical analysis or design software. Source manufacturers are also making measurements of their products and supplying CAD models along with ray data sets for designers. The increasing availability of data has been beneficial to the design community but has caused a large expansion in storage needs for the source manufacturers since each software program uses a unique format to describe the source distribution. In 2012, the Illuminating Engineering Society (IES) formed a working group to understand the data requirements for ray data and recommend a standard file format. The working group included representatives from software companies supplying the analysis and design tools, source measurement companies providing metrology, source manufacturers creating the data and users from the design community. Within one year the working group proposed a file format which was recently approved by the IES for publication as TM-25. This paper will discuss the process used to define the proposed format, highlight some of the significant decisions leading to the format and list the data to be included in the first version of the standard.

Free-standing classrooms at two schools in Southern California were successfully renovated. Noise levels were greatly reduced, and now meet requirements of the ANSI standard. A 1950s style bungalow classroom at the Paradise Canyon School (PCS) in Los Angeles County and a double-trailer classroom at the Wildomar Elementary School (WES) in Riverside County were targeted. The aim was to make classrooms suitable for pupils with severe hearing disabilities. But the methods used apply equally to mainstream classrooms. At both schools the above-ceiling air distribution systems were modified to produce quiet airflow. At PCS, a noisy rooftop heat pump was replaced with a much quieter rooftop heat pump and installation. At WES, a noisy wall-mounted heat pump was replaced with a new unit mounted on an exterior concrete pad. At PCS, exterior noise intrusion was achieved by replacing a poorly performing accordion wall with a permanent wall. Further noise reduction can be achieved by replacing leaky windows. Exterior noise intrusion at WES was obtained by replacing leaky windows. The resulting acoustical improvements are documented. Costs and lessons learned are discussed.

Standards, calibration and quality assurance of 222Rn measurements in Sweden  

NASA Astrophysics Data System (ADS)

Inhaled decay products of 222Rn are the dominant components of the natural radiation exposure to the general population. Limits have been introduced in Sweden, and recommendations were made in 1980 for decreasing indoor 222Rn concentration. The need for the coordinated calibration of measuring instruments as well as for quality assurance was obvious for both health and economic reasons. 222Rn measurements in Sweden are based on standards traceable to the National Institute of Standard and Technology (NIST) through the use of standard reference material 226Ra. Standards for both 222Rn and short-lived 222Rn progeny are described together with the reference instrument adopted for these studies. The calibration of field instruments was performed in a ``radon room'', a climate chamber in which it is possible to vary and monitor the concentration of 222Rn as well as other characteristics of the indoor air such as temperature, humidity, ventilation rate and aerosol concentration. The rules and regulations for field measurements imply a calibration of the instruments yearly, as well as accreditation and training for the companies that carry out the measurements. Examples are given of the official measurement protocols used for the different types of instruments.

Characterization of textile electrodes and conductors using standardized measurement setups.  

PubMed

Textile electrodes and conductors are being developed and used in different monitoring scenarios, such as ECG or bioimpedance spectroscopy measurements. Compared to standard materials, conductive textile materials offer improved wearing comfort and enable long-term measurements. Unfortunately, the development and investigation of such materials often suffers from the non-reproducibility of the test scenarios. For example, the materials are generally tested on human skin which is difficult since the properties of human skin differ for each person and can change within hours. This study presents two test setups which offer reproducible measurement procedures for the systematic analysis of textile electrodes and conductors. The electrode test setup was designed with a special skin dummy which allows investigation of not only the electrical properties of textile electrodes but also the contact behavior between electrode and skin. Using both test setups, eight textile electrodes and five textile conductors were analyzed and compared. PMID:20086274

Standard reference materials: sampling, materials handling, processing, and packaging of NBS (National Bureau of Standards) sulfur in coal standard reference materials  

SciTech Connect

This publication describes in detail the performance of a grant given to Valley Forge Laboratories, Inc., by the National Bureau of Standards, to obtain and prepare four standard reference coals, with nominal sulfur contents of 0.5, 2.0, 3.0, and 4.5 percent to be issued as SRM's 2682, 2683, 2684, and 2685, respectively. All activities pertaining to the sampling, preparation, packaging, and homogeneity testing of the coal SRM's are documented in this report, including a separate description of each of the four coal sampling activities. Protocols used in the development of these Standard Reference Materials are similar to those used in other NBS SRM preparation procedures to ensure that materials used for SRM's have the highest possible homogeneity and stability.

Perceptually standardized imaging of digitized film for comparative ROC measurements  

NASA Astrophysics Data System (ADS)

Primary diagnostic reading of digitized film, displayed on a CRT, requires a quality assurance (QA) that all of the perceptual information, which is accessible from the film when displayed on a light table, can be reproduced on the CRT display. Some of the CRT display parameters are already defined. The DICOM standard 3.14 introduces a contrast transfer function (grayscale display function standard) for minimum contrasts which are defined as single just-noticeable- differences (JND) in luminance. It establishes, throughout the entire intensity range of the data, contrast recognition of single JND resolution and implies linearity of contrast perception. Conventionally, the CRT QA utilizes a SMPTE contrast test pattern of 5% contrast ]13 digital driving levels (DDLs)[ resolution. We developed for the QA of the new standard a perceptual contrast pattern with single DDL resolution (perceptual contrast pattern equals P-pattern). It allows the visual assessment and measurement of perceived contrast linearity at a minimum level 1.2% contrast (3 DDLs). We analyzed, at various room light conditions (0 - 300 cdm-2) and on DICOM 3.14-standardized CRTs of various maximum luminance (110 - 400 cdm-2), the minimum luminance of the CRT that is required for establishing perceptual contrast linearity. We compared the use of the SMPTE pattern and the P-pattern for QA of linearity. The SMPTE pattern was not effective for a statistically significant correlation of contrast linearity with room light and monitor luminance. However, the P-pattern furnished an effective tool for the assessment, measurement or adjustment of contrast linearity. We found that perception of linearity for 3 JND contrasts at low room light conditions (0 - 6 cdm-2) requires a minimum luminance of 10 cdm-2 which is not directly derived from the background luminance of the light reflected from the monitor but may indicate a perceptual threshold value for task performance.

Measures of Inequality: Application to Happiness in Nations.  

PubMed

What is a good measure for happiness inequality? In the context of this question, we have developed an approach in which individual happiness values in a sample are considered as elements of a set and inequality as a binary relation on that set. The total number of inequality relations, each weighed by the distance on the scale of measurement between the pair partners, has been adopted as an indicator for the inequality of the distribution as a whole. For models in which the happiness occurs as a continuous latent variable, an analogous approach has been developed on the basis of differentials. In principle, this fundamental approach results in a (zero) minimum value, and, more importantly, also in a maximum value. In the case where happiness is measured using a k-points scale, the maximum inequality is obtained if all ½N sample members select the lowest possible rating (Eq. 1) and the other ½N the highest possible one (k). This finding even applies to the truly ordinal case, i.e., if the distances between the successive ratings on the scale are unknown. It is, however, impossible to quantify the inequality of some measured sample distribution, unless all distances of the k categories of the scale of measurement are known or at least estimated, either on an empirical basis or on the basis of assumptions. In general, the numerical application of the method to continuous distributions is very complicated. An exploration on the basis of a relatively simple model with a linear probability density function suggests that the inequality of a beta probability distribution with shape parameters a and b increases as the value of these parameters decreases. A contour plot, obtained by numerical integration, demonstrates this relationship in a quantitative way. This approach is applicable to judge the aptness of common statistics of dispersion, among which the standard deviation and the Gini coefficient. The former is shown to be more appropriate than the latter for measuring inequality of happiness within nations. PMID:20835392

Direct Measurement of Recoil Effects on Ar-Ar Standards  

NASA Astrophysics Data System (ADS)

Advances in the precision possible with the Ar-Ar method using new techniques and equipment have led to considerable effort to improve the accuracy of the calibration of interlaboratory standards. However, ultimately the accuracy of the method relies on the measurement of 40Ar*/39ArK ratios on primary standards that have been calibrated with the K-Ar method and, in turn, on secondary standards that are calibrated against primary standards. It is usually assumed that an Ar-Ar total gas age is equivalent to a K-Ar age, but this assumes that there is zero loss of Ar due to recoil. Instead, traditional Ar-Ar total gas ages are in fact Ar retention ages [1] and not, strictly speaking, comparable to K-Ar ages. There have been efforts to estimate the importance of this effect on standards along with prescriptions for minimizing recoil effects [2,3], but these studies have relied on indirect evidence for 39Ar recoil. We report direct measurements of 39Ar recoil for a set of primary and secondary standards using the vacuum encapsulation techniques of [1] and show that significant adjustments to ages assigned to some standards may be needed. The fraction f of 39Ar lost due to recoil for primary standards MMhb-1 hornblende and GA-1550 biotite are 0.00367 and 0.00314 respectively. It is possible to modify the assumed K-Ar ages of these standards so that when using their measured Ar retention 40Ar*/39ArK ratios, one obtains a correct K-Ar age for an unknown, assuming that the unknown sample has zero loss of 39Ar due to recoil. Assuming a primary K-Ar age for MMhb-1 of 520.4 Ma, the modified age would be 522.1 Ma and assuming a primary K-Ar age for GA-1550 of 98.79 Ma [4] yields a modified effective age of 99.09 Ma. Measured f values for secondary standards FCT-3 biotite, FCT-2 sanidine and TCR-2 sanidine are 0.00932, 0.00182 and 0.00039 respectively. Using an R value for FCT-3 biotite relative to MMhb-1 [5], the K-Ar age for this standard would be 27.83 Ma and using R values for FCT and TC sanidines [4] against GA-1550, their K-Ar ages would be 28.06 Ma and 28.41 Ma respectively. For retrospective recalculation purposes, the effective Ar-Ar age of these samples that should yield correct K-Ar ages for unknowns with zero recoil loss would be 28.09 Ma, 28.11 Ma and 28.42 Ma for FCT-3 biotite, FCT-2 sanidine and TCR-2 sanidine respectively. The measured f for FCT-3 appears to explain the R value of it relative to FCT sanidine of 1.0086 found by [8]. From the low T portion of the Ar release spectra of the biotite and amphibole standards, it is clear that the dominant recoil artifact affecting Ar release is the re-implantation mechanism seen in clay samples [1,6,7] and not the loss of 39Ar at the surface of the grain. The geometry of neighboring grains during irradiation and internal defects may predominate in controlling recoil loss. [1] Dong et al., 1995, Science, 267, 355-359.

Methods and procedures used at the National Bureau of Standards to certify sulfur in coal SRM's (Standard Reference Materials) for sulfur content, calorific value, ash content. Final report  

SciTech Connect

This special publication consists of a collection of analytical methods used at NBS for the determination of total sulfur, calorific value, and ash content in four different coals, SRM's 2682, 2683, 2684, and 2685, with nominal sulfur contents of 0.5, 2.0, 3.0, and 4.5 percent, respectively. Also, included are descriptions of methods and procedures used for providing noncertified values for approximately 30 elements including carbon, hydrogen, and nitrogen. These procedures were selected and often specifically developed, by the scientific staff members of NBS, to provide measurements with the best obtainable accuracy and precision. The materials for these SRM's were obtained and processed by Valley Forge Laboratories under a grant from the National Bureau of Standards. Material preparation of the four coal SRM's is described in NBS Special Publication 260-84, Sampling, Materials Handling, Processing, and Packaging of Standard Reference Coal Materials.

Assessing the Life Science Knowledge of Students and Teachers Represented by the K-8 National Science Standards  

PubMed Central

We report on the development of an item test bank and associated instruments based on the National Research Council (NRC) K–8 life sciences content standards. Utilizing hundreds of studies in the science education research literature on student misconceptions, we constructed 476 unique multiple-choice items that measure the degree to which test takers hold either a misconception or an accepted scientific view. Tested nationally with 30,594 students, following their study of life science, and their 353 teachers, these items reveal a range of interesting results, particularly student difficulties in mastering the NRC standards. Teachers also answered test items and demonstrated a high level of subject matter knowledge reflecting the standards of the grade level at which they teach, but exhibiting few misconceptions of their own. In addition, teachers predicted the difficulty of each item for their students and which of the wrong answers would be the most popular. Teachers were found to generally overestimate their own students’ performance and to have a high level of awareness of the particular misconceptions that their students hold on the K–4 standards, but a low level of awareness of misconceptions related to the 5–8 standards.

Measurement precision for repeat examinees on a standardized patient examination.  

PubMed

Examinees who initially fail and later repeat an SP-based clinical skills exam typically exhibit large score gains on their second attempt, suggesting the possibility that examinees were not well measured on one of those attempts. This study evaluates score precision for examinees who repeated an SP-based clinical skills test administered as part of the US Medical Licensing Examination sequence. Generalizability theory was used as the basis for computing conditional standard errors of measurement (SEM) for individual examinees. Conditional SEMs were computed for approximately 60,000 single-take examinees and 5,000 repeat examinees who completed the Step 2 Clinical Skills Examination(®) between 2007 and 2009. The study focused exclusively on ratings of communication and interpersonal skills. Conditional SEMs for single-take and repeat examinees were nearly indistinguishable across most of the score scale. US graduates and IMGs were measured with equal levels of precision at all score levels, as were examinees with differing levels of skill speaking English. There was no evidence that examinees with the largest score changes were measured poorly on either their first or second attempt. The large score increases for repeat examinees on this SP-based exam probably cannot be attributed to unexpectedly large errors of measurement. PMID:21964951

Modeling the wet bulb globe temperature using standard meteorological measurements.  

PubMed

The U.S. Army has a need for continuous, accurate estimates of the wet bulb globe temperature to protect soldiers and civilian workers from heat-related injuries, including those involved in the storage and destruction of aging chemical munitions at depots across the United States. At these depots, workers must don protective clothing that increases their risk of heat-related injury. Because of the difficulty in making continuous, accurate measurements of wet bulb globe temperature outdoors, the authors have developed a model of the wet bulb globe temperature that relies only on standard meteorological data available at each storage depot for input. The model is composed of separate submodels of the natural wet bulb and globe temperatures that are based on fundamental principles of heat and mass transfer, has no site-dependent parameters, and achieves an accuracy of better than 1 degree C based on comparisons with wet bulb globe temperature measurements at all depots.

Harmonizing the American National Standards Institute (ANSI) and International Electrotechnical Commission (IEC) sound level meter specification standards  

NASA Astrophysics Data System (ADS)

It has been over 20 years since the last major revision of the American National Standard Specification for Sound Level Meters, S1.4-1983 (R2002). This is the most extensively referenced ANSI acoustical standard, with wide application to architectural acoustics, soundscapes, environmental noise, and hearing conservation. A new revision is proposed that conforms as closely as possible to the recently developed International Electrotechnical Commission Standard for Electroacoustics-Sound Level Meters Part 1: Specifications, IEC 61672-1 (2002-05). This proposed revision represents an improvement over ANSI S1.4-1983, particularly in its frequency response tolerance limits at high frequencies, and impulse (toneburst) response. Also, it incorporates the high-frequency electrical design goals and tolerance limits for A-weighted response that were specified in Amendment S1.4A-1985, and it maintains the more restrictive low-frequency tolerance limits of the earlier (1983) specification, compared to IEC 61672-1. The proposed revision maintains the laboratory precision Type 0 specification, which is absent in IEC 61672-1, while incorporating the specifications for integrating-averaging sound level meters previously given in ANSI S1.43-1997. Sound level meters which meet the Type 1 and Type 2 specification requirements, respectively, in this S1.4 revision will also meet the Class 1 and Class 2 specification requirements of 61672-1.

Development of an Australian secondary standard for the reference air kerma rate measurement of 125I seeds.  

PubMed

Calibration of a High-Dose-Rate 1000 Plus ionisation chamber and associated electrometer for the determination of reference air kerma rate for 125I brachytherapy seeds has been developed. Traceability was established from ionisation chamber measurements of an Amersham model 6711 125I seed for which a primary standard measurement of reference air kerma rate has been made by the National Institute of Standards and Technology. The status of an Australian secondary standard is to be realised by establishing legal verifying authority from the National Measurement Institute. The calibrated chamber thus provides a measurement from which similar chambers in hospitals may be calibrated. For quality assurance this result was compared with the calibration certificate supplied by the Accredited Dosimetry Calibration Laboratory of the University of Wisconsin, USA. PMID:16250476

A method to measure hyperfine interaction beyond standard statistical limit  

NASA Astrophysics Data System (ADS)

We propose a method to measure the hyperfine interaction between a single electron spin and a nuclear spin and apply it to the trapped electron and the ^15N nuclear spin in a diamond nitrogen-vacancy (NV) center. The electron spin is prepared in a pure quantum state and the nuclear spin acquires an unknown partial polarization as a consequence of the preparation of the electron state. The proposed quantum measurement protocol is independent of the incoherence of the initial nuclear spin state. The model utilizes the time ? of a sequence of quantum operations as well as the number N of repeated sequences to increase the accuracy and the precision of the estimation. The deleterious effect of the electron spin decoherence on the precision during time ? is included in the simulation. While in the statistical limit the standard deviation (measure of imprecision) of the estimation is proportional to 1/?N, the quantum operations in time ? enables the imprecision to decrease faster as 1/? instead of the equivalent statistical limit of 1/??. Thus, the net imprecision of the estimation dips below the statistical limit. The robustness test of our simulation shows that experimental implementation of such a precision measurement is possible.

Sound power measurement standards at laboratory and field environments  

NASA Astrophysics Data System (ADS)

Sound power level measurements, SWLs, of equipment and machinery through direct or comparison methods at laboratory or field conditions, are of increasing importance in terms of regulations and industrial competitiveness. SWLs constitute the input data when modeling the real world, in complex industrial premises for example, as a means for diagnosis and SPL predictions. SWLs have a major technical and economical impact, trying to keep the measurement uncertainties as low as possible, while balancing the testing complexity, time consumption, and costs. In the present work, a description about the calibration of a Reference Sound Source, RSS, B&K 4204 [ISO 6926] is made. The testing survey of normal equipment emitting steady noise and the RSS at different acoustical environments, that range from an hemi-anechoic room to a typical industrial facility is also described. Some measuring methods such as ISO 3745, ISO 3744, ISO 9614-2 are compared for the different sources and environments, yielding some discrepancies between standards as is extensively referred to in literature. A proposal based on a new multiple height microphone array is encouraged at laboratory conditions. Regarding field tests, sound intensity measurements by scanning is extensively adopted for practical reasons, with acceptable results according to our experience.

Aligning science assessment items from the Iowa Testing Program batteries and the State Collaborative on Assessment and Student Standards with the National Science Education Content Standards  

NASA Astrophysics Data System (ADS)

This research study determined the nature and extent of alignment between science content standards and standardized assessments used to measure science proficiency. The alignment process involved external expert blind review and document analysis. Documents reviewed included the National Science Education Content Standards (NSECS), the Iowa Tests of Basic Skills (ITBS), the Iowa Tests of Educational Development (ITED) and the State Collaborative on Assessment and Student Standards (SCASS). Webb's alignment criteria of Categorical Concurrence, Depth of Knowledge, Range of Knowledge Correspondance and Balance of Representation were used to determine acceptable alignment. A pilot study was conducted on Form B ITBS and ITED items and Phase II SCASS items. Inter-rater reliability was determined and consensus building dialogs were conducted. The three research questions were: What is the nature and extent of alignment between the NSECS and Form A ITBS, Levels 9--14? What is the nature and extent of alignment between the NSECS and Form ITED, Levels 15--17/18? What is the nature and extent of alignment between the NSECS and Phase III SCASS Science items? The major findings indicated that none of the assessments had comprehensive alignment of all of the NSECS. However, most did have acceptable categorical concurrence with Science as Inquiry, Physical Science, Life Science, Earth and Space Science. Most did not have acceptable Categorical Concurrence with Science and Technology, Science in Personal and Social Perspectives and History and Nature of Science. More than half of the assessment items were categorized Beyond Knowledge level of Bloom's Taxonomy (Depth of Knowledge). Of the standards with acceptable Categorical Concurrence between 43% and 86% of the fundamental components aligned (Range of Knowledge Correspondence). And the Index of Balance of representation indicated an equal distribution of the items across all of the fundamental components of the NSECS with acceptable alignment. Further implications and future research questions, in addition to an elaboration of the fundamental components assessed by each standardized assessment analyzed are explored in the paper.

The Space Weather Compendium: Trials and Tribulations to Aligning Existing Lessons with the National Standards  

NASA Astrophysics Data System (ADS)

A major challenge facing successful programs in solar and space physics education is finding appropriate standards-based lessons at the elementary, middle and high school levels. High-quality lessons follow a specific set of criteria to facilitate science literacy in solar and space physics within a defined scope and sequence. Without this, students fail to grasp the interconnectedness of the science and lack a sense of the bigger picture. Because teachers often have limited familiarity with the science of solar and space physics, finding solar and space physics lessons that align with state and national standards can be a challenge. CU-LASP's Space Weather Compendium is a compilation of existing lessons and activities from a wide range of sources that we have aligned to national and Colorado state standards and placed within a grade- appropriate scope and sequence. Here, we explore the challenges involved in creating a compendium of activities that align with national standards, and how to successfully meet space physics literacy goals at the elementary, middle and high school levels. In addition, we outline the additional supporting materials that we have found teachers need in order to bring the excitement of solar and space physics into the classroom effectively.

Analysis of primary fine particle national ambient air quality standard metrics.  

PubMed

In accordance with the Clean Air Act, the U.S. Environmental Protection Agency (EPA) is currently reviewing its National Ambient Air Quality Standards for particulate matter, which are required to provide an adequate margin of safety to populations, including susceptible subgroups. Based on the latest scientific, health, and technical information about particle pollution, EPA staff recommends establishing more protective health-based fine particle standards. Since the last standards review, epidemiologic studies have continued to find associations between short-term and long-term exposure to particulate matter and cardiopulmonary morbidity and mortality at current pollution levels. This study analyzed the spatial and temporal variability of fine particulate (PM2.5) monitoring data for the Northeast and the continental United States to assess the protectiveness of various levels, forms, and combinations of 24-hr and annual health-based standards currently recommended by EPA staff and the Clean Air Scientific Advisory Committee. Recommended standards have the potential for modest or substantial increases in protection in the Northeast, ranging from an additional 13-83% of the population of the region who are living in areas not likely to meet new standards and thereby benefiting from compliance with more protective air pollution controls. Within recommended standard ranges, an optimal 24-hr (98th percentile)/annual standard suite occurs at 30/12 microg/m3, providing short- and long-term health protection for a substantial percentage of both Northeast (84%) and U.S. (78%) populations. In addition, the Northeast region will not benefit as widely as the nation as a whole if less stringent standards are selected. Should the 24-hr (98th percentile) standard be set at 35 microg/m3, Northeast and U.S. populations will receive 16-48% and 7-17% less protection than a 30 microg/m3 standard, respectively, depending on the level of the annual standard. A 30/12 microg/m3 standard suite also provides nearly equivalent 24-hr and annual control of PM2.5 distributions across the United States, thereby ensuring a more uniform and consistent level of protection than unmatched or "controlling" and "backstop" standards. This could occur even within EPA staff's recommended range of standard suites, where 22-43% of the monitors in the country could meet a controlling standard but fail to meet the combined backstop standard, resulting in inconsistent short- and long-term protection across the country. An equivalent standards combination of 30/12 microg/m3 would minimize the wide variation of protectiveness of 24-hr and annual PM2.5 concentrations. Furthermore, given recent associations of subdaily exposures and acute adverse health effects, in the absence of a subdaily averaging metric, a stringent 24-hr standard will more effectively control maximum hourly and multihourly peak concentrations than a weaker standard.

Breast composition measurements using retrospective standard mammogram form (SMF)  

NASA Astrophysics Data System (ADS)

The standard mammogram form (SMF) representation of an x-ray mammogram is a standardized, quantitative representation of the breast from which the volume of non-fat tissue and breast density can be easily estimated, both of which are of significant interest in determining breast cancer risk. Previous theoretical analysis of SMF had suggested that a complete and substantial set of calibration data (such as mAs and kVp) would be needed to generate realistic breast composition measures and yet there are many interesting trials that have retrospectively collected images with no calibration data. The main contribution of this paper is to revisit our previous theoretical analysis of SMF with respect to errors in the calibration data and to show how and why that theoretical analysis did not match the results from the practical implementations of SMF. In particular, we show how by estimating breast thickness for every image we are, effectively, compensating for any errors in the calibration data. To illustrate our findings, the current implementation of SMF (version 2.2?) was run over 4028 digitized film-screen mammograms taken from six sites over the years 1988-2002 with and without using the known calibration data. Results show that the SMF implementation running without any calibration data at all generates results which display a strong relationship with when running with a complete set of calibration data, and, most importantly, to an expert's visual assessment of breast composition using established techniques. SMF shows considerable promise in being of major use in large epidemiological studies related to breast cancer which require the automated analysis of large numbers of films from many years previously where little or no calibration data is available.

Applying IEEE storage system management standards at the National Storage Laboratory  

SciTech Connect

Since its inception in 1990, the IEEE Storage System Standards Working Group has identified storage-system management as an area in need of further development The pressing need for standards in storage-system management arises from the requirement to exchange management information and to provide control in a consistent predictable manner between the components of a storage system. An appropriate set of management standards will allow multiple vendors to supply storage management subsystems or applications that are integral to or compatible with new storage systems conforming to future IEEE standards. An early, practical application of IEEE storage-system-management work is being pursued at the National Storage Laboratory (NSL), a recently-formed industrial collaboration at Lawrence Livermore National Laboratory. The NSL`s purpose is to develop advanced hardware and software technologies for high-performance, distributed storage systems. Since storage system management is of critical concern, it is being explored in depth at the NSL. Work was initiated to define basic management requirements and develop generalized graphical-user-interface tools using remote-procedure-call mechanisms to implement the NSL`s conceptual management framework. Several constraints were imposed on the development of early versions of this work to maintain compatibility with the NSL`s underlying UniTree-based software architecture and to provide timely prototypes and proof of concept. The project leverages the on-going standards work of the IEEE Storage System Standards Working Group (SSSWG) and also explores some of the relationships and interactions between IEEE storage-system management and more well known management methods for distributed systems and networks. It will have long term benefits by providing ``real-life`` storage-system-management requirements to the IEEE SSSWG for validation of evolving standards.

A reevaluation of the National Emission Standards for Hazardous Air Pollutants (NESHAP - 40 CFR 61, Subpart H) program at Sandia National Laboratories, New Mexico  

SciTech Connect

The initial National Emission Standards for Hazardous Air Pollutants (NESHAP - 40 CFR 61, Subpart H) Program at Sandia National Laboratories, New Mexico (SNL/NM) required: (1) continuous air monitoring of sources if the calculated effective dose equivalent (EDE) to the maximum exposed individual (MEI) was > 0.1 mrem/yr; (2) the determination of emissions based on measurements or measured parameters if the EDE to the MEI was < 0.1 mrem/yr; and (3) the calculation of worst case releases when the expected air concentrations were below detection limits using standard monitoring equipment. This conservative interpretation of the regulation guided SNL/NM to model, track, and trend virtually all emission sources with the potential to include any radionuclides. The level of effort required to implement these activities was independent of the EDE contributing from individual sources. A recent programmatic review found the NESHAP program to be in excess of the legal requirements. A further review found that, in summation, 13 of 16 radionuclide sources had a negligible impact on the final calculated EDE to the MEI used to demonstrate compliance at 20 separate on-site receptor locations. A reevaluation was performed to meet the legal requirements of 40 CFR 61, Subpart H, and still be reasonable and appropriate under the existing circumstances.

National Emission Standards for Hazardous Air Pollutants - Radionuclide Emissions, Calendar Year 2011  

SciTech Connect

The U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office operates the Nevada National Security Site (NNSS) and North Las Vegas Facility (NLVF). From 1951 through 1992, the NNSS was the continental testing location for U.S. nuclear weapons. The release of radionuclides from NNSS activities has been monitored since the initiation of atmospheric testing. Limitation to underground detonations after 1962 greatly reduced radiation exposure to the public surrounding the NNSS. After nuclear testing ended in 1992, NNSS radiation monitoring focused on detecting airborne radionuclides from historically contaminated soils. These radionuclides are derived from re-suspension of soil (primarily by wind) and emission of tritium-contaminated soil moisture through evapotranspiration. Low amounts of legacy-related tritium are also emitted to air at the NLVF, an NNSS support complex in North Las Vegas. To protect the public from harmful levels of man-made radiation, the Clean Air Act, National Emission Standards for Hazardous Air Pollutants (NESHAP) (Title 40 Code of Federal Regulations [CFR] Part 61 Subpart H) limits the release of radioactivity from a U.S. Department of Energy (DOE) facility to that which would cause 10 millirem per year (mrem/yr) effective dose equivalent to any member of the public. This limit does not include radiation unrelated to NNSS activities. Unrelated doses could come from naturally occurring radioactive elements, from sources such as medically or commercially used radionuclides, or from sources outside of the United States, such as the damaged Fukushima nuclear power plant in Japan. Radionuclides from the Fukushima nuclear power plant were detected at the NNSS in March 2011 and are discussed further in Section III. The NNSS demonstrates compliance with the NESHAP limit by using environmental measurements of radionuclide air concentrations at critical receptor locations. This method was approved by the EPA for use on the NNSS in 2001 and has been the sole method used since 2005. Six locations on the NNSS have been established to act as critical receptor locations to demonstrate compliance with the NESHAP limit. These locations are actually pseudo-critical receptor stations, because no member of the public actually resides at these onsite locations. Compliance is demonstrated if the measured annual average concentration is less than the NESHAP Concentration Levels (CLs) for Environmental Compliance listed in 40 CFR 61, Appendix E, Table 2. For multiple radionuclides, compliance is demonstrated when the sum of the fractions (determined by dividing each radionuclide's concentration by its CL and then adding the fractions together) is less than 1.0. In 2011, the potential dose from radiological emissions to air, resulting from both current and past NNSS activities, at onsite compliance monitoring stations was well below the 10 mrem/yr dose limit. Air sampling data collected at all air monitoring stations had average concentrations of radioactivity that were a fraction of the CL values. Concentrations ranged from less than 1% to a maximum of 12.2% of the allowed NESHAP limit. Because the nearest member of the public resides about 20 kilometers from potential release points on the NNSS, dose to the public would be only a small fraction of the value measured on the NNSS. The potential dose to the public from NLVF emissions was also very low at 0.000024 mrem/yr, more than 400,000 times lower than the 10 mrem/yr limit.

This limit does not include radiation unrelated to NNSS activities. Unrelated doses could come from naturally occurring radioactive elements, from sources such as medically or commercially used radionuclides, or from sources outside of the United States, such as those from the damaged Fukushima nuclear power plant in Japan. Because this report is intended to discuss radioactive air emissions during calendar year 2010, data on radionuclides in air from the 2011 Fukushima nuclear power plant releases are not presented but will be included in the report for calendar year 2011. The NNSS demonstrates compliance with the NESHAP limit by using environmental measurements of radionuclide air concentrations at critical receptor locations (U.S. Environmental Protection Agency [EPA] and DOE, 1995). This method was approved by the EPA for use on the NNSS in 2001(EPA, 2001a) and has been the sole method used since 2005. Six locations on the NNSS have been established to act as critical receptor locations to demonstrate compliance with the NESHAP limit.

Because the nearest member of the public resides about 20 kilometers from potential release points on the NNSS, dose to the public would be only a small fraction of that measured on the NNSS. The potential dose to the public from NLVF emissions was also very low at 0.000032 mrem/yr, more than 300,000 times lower than the 10 mrem/yr limit.

UV-B screening by tropospheric ozone: Implications for the National Ambient Air Quality Standard  

SciTech Connect

Tropospheric ozone reduces human exposure to harmful ultraviolet-B (UV-B) radiation. A 10-ppb decrease in seasonal average concentrations of ozone (about 20%) is estimated to lead to increases in cancers and cataracts valued at $0.29 billions to $1.1 billion annually. EPA in its ongoing review of the National Ambient Air Quality Standard for ozone should set a standard to minimize all identifiable health effects, including UV-B radiation-related effects. If these estimates are confirmed, this approach may reduce avoidable cancers, cataracts, and deaths by leading to a different standard than that recently proposed in a program already costing more than $20 billion annually. 44 refs.

Cervical cancer risk levels in Turkey and compliance to the national cervical cancer screening standard.  

PubMed

Cervical cancer screening with Pap smear test is a cost-effective method. The Ministry of Health in Turkey recommends that it be performed once every five years after age 35. The purpose of this study was to determine the cervical cancer risk levels of women between 35 and 69, and the intervals they have the Pap smear test, and to investigate the relation between the two. This study was performed on 227 women aged between 35 and 69 living in Balçova District of ?zmir province. Using the cervical cancer risk index program of Harvard School of Public Health, the cervical cancer risk level of 70% of the women was found below average, 22.1% average, and 7.9% above average. Only 52% of the women have had Pap smear test at least once in their lives. The percentage screening regularly in conformity with the national screening standard was 39.2%. Women in the 40-49 age group, were married, conformed significantly more (p<0.05) to the national screening standard. Compliance also increased with the level of education and decreased with the cervical cancer risk level (p<0.05). A logistic regression model was constructed including age, education level, menstruation state of the women and the economic level of the family. Not having the Pap smear test in conformity with the national cervical cancer screening standard in 35-39 age group was 2.52 times more than 40-49 age group, while it was 3.26 times more in 60-69 age group (p< 0.05). Not having Pap smear test in 35-39 age group more than other groups might result from lack of information on the cervical cancer national screening standard and the necessity of having Pap smear test. As for 60-69 age group, the low education level might cause not having Pap smear test. Under these circumstances, the cervical cancer risk levels should be determined and the individuals should be informed. Providing Pap smear test screening service to individuals in the target group of national screening standard, as a public service may resolve the inequalities due to age and educational differences.

Consistency of the National Realization of Dew-Point Temperature Using Standard Humidity Generators  

NASA Astrophysics Data System (ADS)

The comparison of two high-range standard humidity generators used by Instituto Nacional de Técnica Aeroespacial to realize dew-point temperature in the range from -10 °C to +95 °C has been performed using state-of-the art transfer standards and measurement procedures, over their overlapping range from -10 °C to +75 °C. The aim of this study is to investigate the level of agreement between the two generators, to determine any bias, and to quantify the level of consistency of the two realizations. The measurement procedures adopted to minimize the effect of the influence factors due to the transfer standards are described, and the results are discussed in the context of the declared calibration and measurement capabilities (CMCs).

Middle school assessment and the nature of science as related to the National Science Education Standards  

NASA Astrophysics Data System (ADS)

Scope and method of study. The purpose of this descriptive study was to provide information by identifying many of the good science teaching behaviors and assessment practices of middle school teachers in Oklahoma City as related to assessment behaviors expressed in the National Science Education Standard B, Part 1. Participants were thirty Oklahoma City middle school teachers who responded to a two-part interview. The demographic survey and research questionnaire responses were classified into fifty-four basic themes from which a data base was compiled to demonstrate science teaching behaviors that could be identified as the nature of science and as assessment practices for evaluating the nature of science in the National Science Education Standards. Findings and conclusions. Teachers have continued to teach science in the way that they experienced science or were trained. Few of these teachers have used the true concept of portfolios, rubric assessment, and performance assessment much less lab activities. Yet, through participation in a traditional competition such as science fair, the majority of teachers provided students (usually at their own expense) with some laboratory experiences and techniques. The research also indicated that teachers who had science endorsement reported using fewer of those process skills associated with teaching the nature of science (also called the process skills). It also indicated that teachers who have entered the field of teaching from private industry demonstrated great background in knowledge yet demonstrated little participation in inquiry oriented activities. The research also indicated that those teachers who had been exposed to the National Science Education Standards did describe assessment practices from the standards.

Federal standards and procedures for the National Watershed Boundary Dataset (WBD)  

USGS Publications Warehouse

The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. This document establishes Federal standards and procedures for creating the WBD as seamless and hierarchical hydrologic unit data, based on topographic and hydrologic features at a 1:24,000 scale in the United States, except for Alaska at 1:63,360 scale, and 1:25,000 scale in the Caribbean. The data within the WBD have been reviewed for certification through the 12-digit hydrologic unit for compliance with the criteria outlined in this document. Any edits to certified data will be reviewed against this standard prior to inclusion. Although not required as part of the framework WBD, the guidelines contain details for compiling and delineating the boundaries of two additional levels, the 14- and 16-digit hydrologic units, as well as the use of higher resolution base information to improve delineations. The guidelines presented herein are designed to enable local, regional, and national partners to delineate hydrologic units consistently and accurately. Such consistency improves watershed management through efficient sharing of information and resources and by ensuring that digital geographic data are usable with other related Geographic Information System (GIS) data. Terminology, definitions, and procedural information are provided to ensure uniformity in hydrologic unit boundaries, names, and numerical codes. Detailed standards and specifications for data are included. The document also includes discussion of objectives, communications required for revising the data resolution in the United States and the Caribbean, as well as final review and data-quality criteria. Instances of unusual landforms or artificial features that affect the hydrologic units are described with metadata standards. Up-to-date information and availability of the hydrologic units are listed at http://www.nrcs.usda.gov/wps/portal/nrcs/detail/national/technical/nra/dma/?&cid=nrcs143_021630/.
