    Close-up of a stone in the NIST stone wall

    No full text
    The NIST stone wall was built using 2,352 stones from 47 US states and 320 from 16 foreign countries. The wall is approximately 12 m long, 4 m high, 0.6 m thick at the bottom, and 0.3 m at the top. The aim of the wall construction was to study the aging process of stones used in construction under outside weathering conditions

    JANET B. MILLER NBS/NIST: 1969-1981 and 1988-2007 INDUCTED: 2017 Birth: 5 January 1947, Bethesda, Maryland EDUCATION: Wake Forest University, BA (Psychology), 1969 CITATION: For exceptional contributions in financial management and budget execution and formulation for NBS and NIST. POSITIONS HELD AT NBS/NIST: Administrative Intern, Personnel Division, Associate Director for Administration (ADA), 1969-1970 Budget Analyst, Budget Division, ADA, 1970-1976 Senior Budget Analyst, Financial Management Division, ADA, 1976-1977 Supervisory Budget Analyst, Budget Office, Associate Director for Programs, Budget, and Finance (ADPBF), 1977-1979 Special Assistant to the Budget Officer, Budget Office, ADPBF, 1979-1981 Budget Analyst/Lead Budget Analyst, Budget Office, Office of the Director (OD), 1988-1995 Group Leader, Formulation and Financial Management, Budget Office, OD, 1995-1997; Budget Office, Chief Financial Officer (CFO), 1997-1998 Acting Budget Officer, Budget Office, CFO, 1998-1999 Group Leader, Formulation and Financial Management, Budget Division, Director for Administration and CFO, 1999-2004; Budget Division, OD, 2004-2007 SIGNIFICANCE OF WORK: Ms. Miller worked closely with the NIST Director, senior management, and financial personnel across the organization to support the NIST mission by securing appropriated funding through the budget process and ensuring proper stewardship of agency resources. She played a critical financial management role during a period of significant growth in NIST programs, responsibilities, and appropriation accounts; increasing external requirements (CFO Act, GPRA, FFMIA, and subsequent legislation) and audit; frequent organizational and management changes; and unprecedented technological innovation, challenges (Y2K), and system conversions. Her attention to detail and in-depth knowledge of NIST budget activities made her a reliable, respected expert among NIST colleagues and officials at the Department of Commerce, Office of Management and Budget, and Congressional Budget Office. She received recognition for automation efficiencies and increased accuracy in budget formulation and initiative pricing; documentation of NIST fiscal policy and procedures; crafting of the Management Discussion and Analysis for the end-of-year financial statements, part of a team effort that led to the Department’s first clean audit opinion in 1999; and significant contributions to the transition from the pre-2004 NIST Cost Accounting System to the Department-wide Commerce Administrative Management System.

    Impact Toughness Modification of NIST Low-Energy Charpy Verification Specimens for Testing at Room Temperature

    No full text
    The possibility for the National Institute for Standards and Technology (NIST) to certify Charpy reference specimens for testing at room temperature (21 �C � 1 �C) instead of _40 �C was investigated in a previous study, in which a slightly increased likelihood of specimen jamming was observed at the low-energy level (13 J to 20 J). Moreover, there is a concern that the higher impact toughness of low-energy verification specimens at room temperature would not allow the same Charpy machine features to be verified as in the case of low-temperature (_40 �C) tests, namely, the linear elastic behavior of the sample and the very high maximum forces (typically larger than 33 kN). In this paper, we report on the change in the mechanical properties (hardness and absorbed energy) of the American Iron and Steel Institute (AISI) 4340 steel low-energy specimens that ensues from the modification of the temperature of the final tempering heat treatment. We established that, if low-energy verification specimens are tempered at 300 �C for 2 h and then air cooled, they exhibit equivalent impact toughness (13 J to 20 J) and postimpact behavior (specimen halves projected backward at high speed) at room temperature as compared to specimens currently on sale for testing at _40 �C. Their hardness is however increased to above 49 HRC on the Rockwell scale. The minimum hardness requirement for low-energy verification specimens, currently set at 44 HRC in NIST specifications, will have to be increased to 49 HRC
