1. Flat Frequency Response in the Electronic Measurement of the Boltzmann Constant
Topic: Energy
Published: 6/1/2013
Authors: Jifeng Qu, Horst Rogalla, Yang Fu, Jianqiang Zhang, Alessio Pollarolo, Samuel Paul Benz
Abstract: A new quantum voltage calibrated Johnson noise thermometer (JNT) was developed at NIM to demonstrate the electrical approach that determines the Boltzmann constant k by comparing electrical and thermal noise power. A measurement with an integration p ...

2. Johnson Noise Thermometry Measurement of the Boltzmann Constant with a 200 Ohm Sense Resistor
Topic: Energy
Published: 6/1/2013
Authors: Alessio Pollarolo, Tae H. Jeong, Samuel Paul Benz, Horst Rogalla
Abstract: In 2010, NIST measured the Boltzmann constant k with an electronic technique that measured the Johnson noise of a 100 Ω resistor at the triple point of water (TPW) and used a voltage waveform synthesized with a quantized voltage noise source (QV ...

3. Assessment of Real-Time Factory Performance through the Application of Multi-Relationship Evaluation Design
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7911
Topic: Energy
Published: 4/17/2013
Authors: Brian A Weiss, John A Horst, Frederick M Proctor
Abstract: Successful operations within manufacturing environments require both accurate and precise information flow from one operation to the next. Incorrect, too little, or too much information can slow the manufacturing process and/or result in poor qua ...

4. Block-copolymer healing of simple defects in a chemoepitaxial template
Topic: Energy
Published: 4/11/2013
Authors: Paul Nathan Patrone, Gregg M. Gallatin
Abstract: Using a phase-field model of block copolymers (BCPs), we characterize how a chemoepitaxial template with parallel lines of arbitrary width affects the BCP microdomain shape. The model, which is an extension of the Leibler-Ohta-Kawasaki theory, accoun ...

5. Strategies to Achieve Net-Zero Energy Homes: A Framework for Future Guidelines Workshop Summary Report
Series: Special Publication (NIST SP)
Report Number: 1140
Topic: Energy
Published: 4/5/2013
Author: Nancy A McNabb
Abstract: The National Institute of Standards and Technology (NIST) Measurement Science Roadmap for Net-Zero Energy Buildings Workshop Report (NIST TN 1660 – March 2010) identified a number of broad challenges to achieving NZE high-performance green buildi ...

6. Effects of fiber gripping methods on the single fiber tensile test: I. Non parametric statistical analysis
Topic: Energy
Published: 2/15/2013
Authors: Jae Hyun Kim, Nathanael A Heckert, Stefan D Leigh, Haruki Kobayashi, Walter G McDonough, Kirk D Rice, Gale Antrus Holmes
Abstract: Single fiber tensile tests using two different gripping methods were carried out on various fiber lengths. One method (the glue-tab grip) consists of mounting a fiber onto a rigid tab as specified in ASTM C1557-03 using an adhesive, while the other ( ...

9. Performance Improvement of a Roof Top Air-Conditioning Unit by Refrigerant Circuitry Optimization
Topic: Energy
Published: 1/26/2013
Authors: Sunil Lee, David A Yashar, Piotr A Domanski
Abstract: In this experiment-aided simulation study, we achieved the performance improvement of a Roof Top Unit (RTU) by optimizing an evaporator’s refrigerant circuitry using evolutionary algorithms. The system used in this study was a 2-stage 7.5 Ton RTU wit ...
