Advanced Mechanical Characterization of Mesoscale Materials

Ongoing
Knowledge of a material’s mechanical properties is key to designing safe and reliable structural components for applications ranging in size from medical implants to large civil engineering structures. Traditionally, a material’s mechanical properties are measured by performing mechanical tests on

Advanced Metering in Smart Distribution Grids

Completed
Objective: To advance measurement science for the performance of smart meters and associated metering standards and test procedures that will enable accurate and fair electricity metering needed for the smart grid, by 2016. What is the new technical idea? This project will develop test procedures

Atomic Spectroscopy Data Center

Ongoing
The Atomic Spectroscopic Data Center at NIST provides the most comprehensive collection of atomic spectroscopy data in the world. We monitor scientific literature and maintain bibliographic databases of all papers containing spectroscopic data. By evaluating and compiling data on energy levels

Building Integration with Smart Grid

Ongoing
Objective - To develop the measurement science for industry standards that will enable interconnection of home and building automation and control systems with a future "smart" utility grid, provide consumers with energy usage information, and support industry efforts to develop the needed standards

Building Joint Sealant Service Life Prediction

Ongoing
The primary building sealant problem is that no method exists to provide high quality data for elucidating the relative importance of the k = 4 major weathering factors: X1: temperature, X2: humidity, X3: ultra-violet radiation, and X4: mechanical loading(and interactions) on the change in pre

Cell Line Authentication

Ongoing
Cell Line Authentication – The scientific community has responded to the misidentification of human cell lines with validated methods to authenticate these cells; however, there are few assays available for nonhuman cell line identification. We have developed multiplex polymerase chain reaction (PCR

Characterization of 3D Photovoltaics

Completed
First Generation (thick layers of crystalline silicon) and Second Generation (thin films of CdTe, CIGS, and related materials) PV devices are both well established in the marketplace, with well defined techniques for fabrication and characterization. Third Generation PV encompasses a wide diversity

Commissioning Building Systems for Improved Energy Performance

Ongoing
Objective - To improve the operating efficiency of building systems by providing the measurement science needed to develop improved building commissioning techniques that utilize embedded capabilities of building control systems, and accelerate the adoption of cost-effective commissioning as

Comparison of Internet Congestion-Control Algorithms

Complex systems are generically characterized by a large number of factors and a large number of potential responses, hence statistical questions immediately present themselves as to 1. What should be measured? 2. What experiment design should be used to generate content-full data? 3. How should

Computational Biology: Comparison of Cell Image Segmentation Algorithms

Ongoing
The Problem: The initial project problem was to determine whether image analysis techniques existed (or could be developed by the ITL groups) which would assist in the automatic differentiation of the A10 and 3T3 cell lines. The larger problem at hand was to determine what factors (and interactions)

Cyber-Physical Systems/Internet of Things for Smart Cities

Objective - To provide the measurement science and standards-based foundations for interoperable, replicable, scalable, and trustworthy cyber-physical systems that can be readily and cost-effectively deployed by cities and communities of all types and sizes to improve their efficiency

Cyber-Physical Systems/Internet of Things Testbed

Ongoing
Objective - To develop general design principles useful to all cyber-physical systems testbed developers and the co-simulation community; to develop specific design concepts to guide the development, operation, and evolution of NIST’s IoT/CPS testbed; and to establish a cross-sector IoT/CPS testbed

Cyber-Physical Systems and Internet of Things Foundations

Ongoing
Objective - To provide a common technical and conceptual foundation for CPS and IoT that enables conceptualization, realization and assurance across all domains, including a comprehensive and traceable methodology for meeting all stakeholder concerns throughout any systems engineering process and

Cybersecurity for Smart Grid Systems

Completed
Objective: To develop the measurement science needed to advance the development and standardization of cybersecurity, including privacy, policies, measures, procedures, and resiliency, in the smart electric grid. What is the new technical idea? As a result of deployment of new smart grid

Electric Power Metrology and the Smart Grid

Ongoing
Major advancements in electric power generation, transmission, distribution and loads over the last 20 years have led to improvements, reliability, robustness, efficiency and energy security unlike anything from the proceeding 80 years. Combined, this power grid modernization has been called the

Electron Beam Ion Trap (EBIT) Facility

Ongoing
The NIST EBIT is a table-top device which can produce matter in excess of ten million degrees Kelvin. At these temperatures, even the heaviest atoms shed most of their electrons. The highly charged ions which result are trapped by a configuration of electric and magnetic fields in an ultrahigh
