This document describes recommendations provided to the National Institute of Justice's (NIJ) Special Technical Committee (STC) for the revision of the Stab Resistant Body Armor Standard related to the specification of idealized bust surrogates for armor
A new method for fabrication of high current density field emitters based on nanoporous silicon carbide is presented. The emitters are monolithic structures which do not require high temperature gas phase synthesis and the process is compatible with
The method to build an analysis function described in ISO 6143, Gas analysis - Comprarison methods for determining and checking the composition of calibration gas mixtures, is extended to recognize the typically small number of instrumental readings
Common Logic (CL) is an ISO standard that specifies a family of knowledge representation languages. The function of modules within CL is to support local context with a local domains of discourse. Modules play a crucial role since they enable users to

Recently a test of nonclassicality for a single qubit was proposed R. Alicki and N. Van Ryn, J. Phys, A: Math. Theor. 41, 062001 2008. We present an optimized experimental realization of this test leading to a 46standard deviation violation of classicality
The technical activities of the Materials Reliability Division during Fiscal year 1998 are summarized. The Division has eighteen research projects in five program areas: Metals Processing (3), Ultrasonic Characterization of Materials (9), Electronic
Consider an ill-posed problem transformed if necessary so that the errors in the data are independent, identically normally distributed with mean zero and variance 1. We evaluate a method proposed by Rust for choosing the regularization parameter that

Powder-in-Tube (PIT) Nb 3Sn conductors have been fabricated utilizing a low-cost intermetallic Cu 5Sn 4 powder as the tin source. A novel octagonal PIT design that incorporates dispersion strengthened copper as well as a hexagonal PIT design were
A recent evaluation of the accuracy of National Physical Laboratory (NPL) primary frequency standard NPL CsF1 gives an overall frequency uncertainty of δŅ/Ņ 0 = 1 × 10 -15. This stated uncertainty includes a correction of a frequency bias of δŅ/Ņ 0 = 8 ×

This paper describes the construction, calibration, and use of a precision capacitance-based metrology for the measurement of the thermal and hygrothermal (swelling) expansion of thin films. It is demonstrated that with this version of our capacitance cell
