The National Institute of Standards and Technologys Standards Coordination Office offers training to government agencies on standards, conformity assessment and related topics. One such course, Setting Standards: A Simulation Exercise in Strategy and

This paper discusses system security policies. System policies are the set of rules that when implemented afford a strategy for the protection of information. The policy objectives are diverse and span the social-economic spectrum. System policies govern
In this paper, an energy-efficient strategy is proposed for tracking a moving target in a mobile sensor network. The energy expenditure of the sensors in the network is assumed to be due to communication, sensing and movement. First, the target area is
This report summarizes the work of the Complex Systems Program within NIST s Information Technology Laboratory. The Overview presents some background material and a high-level overview of the Program s activities including significant technical
We report a simple strategy to control the pressure-driven flow rates from fluid reservoirs to a microchip in an efficient and compact fashion. We demonstrate that using a floating reservoir, less than 1 percent change in flow rate per ml of delivered

Advancement in MEMS-based sensors brings a new challenge for system-on-a-chip (SoC) design integration where analog and digital circuits coexist on a common substrate with the actual sensing platform. Integration of these MEMS-based sensors into an SoC

A strategy successfully used by manufacturing companies is to develop product families so as to offer a variety of products with reduced development costs. This paper introduces our initial research on the representation of the evolution of product
An evaporative cooling strategy that uses a two-component Fermi gas was employed to cool a magnetically trapped gas of 7 x 10 5 40K atoms to 0.5 of the Fermi temperature T f. In this temperature regime, where the state occupation at the lowest energies has
