1. 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 ...

2. Commissioning Cost-Benefit and Persistence of Savings: A Report on Cost-Effective Commissioning of Existing and Low Energy Buildings
Series: Technical Note (NIST TN)
Report Number: 1727
Topic: Energy
Published: 9/17/2012
Authors: Hannah Friedman, Marti Frank, David Claridge, Kristin Heinemeier, Kim Crossman, Eliot Crowe, Cory Toole, Natascha Sylvia Milesi-Ferretti, Daniel Choniere
Abstract: Commissioning of new and existing buildings has been shown to reduce energy usage and can also produce non-energy related benefits such as improved occupant comfort. When compared with other initiatives such as installation of high efficiency equ ...

3. Confocal Microscopy Analysis of Breech Face Marks on Fired Cartridge Cases from Ten Consecutively Manufactured Pistol Slides
Topic: Energy
Published: 7/1/2012
Authors: Xiaoyu A Zheng, Robert Meryln Thompson, Todd Weller
Abstract: Ten (10) pistol slides with consecutively manufactured breech faces, were obtained from Sturm, Ruger Co, Inc. A total of nine (9) test fires from each pistol, for a total of ninety (90) test fired cartridge cases, were compared using comparison micr ...

4. Johnson Noise Thermometry Measurement of the Boltzmann Constant with a 200 Ohm Sense Resistor
Topic: Energy
Published: 7/1/2012
Authors: Alessio Pollarolo, Tae H. Jeong, Samuel Paul Benz, Horst Rogalla
Abstract: In 2010 NIST measured the Boltzmann constant k by use of an electronic technique that measured the Johnson noise of a 100 Ohm resistor at the triple point of water (TPW). The NIST Johnson noise thermometry (JNT) system used as a reference a voltage ...

5. A versatile light-emitting-diode-based spectral response measurement system for photovoltaic device characterization
Topic: Energy
Published: 6/29/2012
Authors: Behrang H Hamadani, John F Roller, Brian P Dougherty, Howard W Yoon
Abstract: An absolute differential spectral response measurement system for solar cells is presented. The system couples an array of light emitting diodes (LEDs) with an optical waveguide to provide large area illumination. Two unique yet complementary measur ...

6. Detection of Cutting Phenomena Using Sensor Fusion
Topic: Energy
Published: 6/8/2012
Authors: John A Slotwinski, Gregory W Vogl, Robert W Ivester, Ian Younker
Abstract: This paper presents an investigation of the application of a suite of sensors for simultaneous in-situ measurements of machining processes. While not every individual sensor responds to all machining phenomena, the suite of sensors together responds ...

7. Application of the Advanced Distillation Curve Method to the Variability of Jet Fuels
Topic: Energy
Published: 5/24/2012
Authors: Jessica Lynne Burger, Thomas J Bruno
Abstract: In this paper, we report the application of the advanced distillation-curve approach to the gas turbine fuels Jet-A, JP-8, and JP-5, in order to obtain information about the variability of these gas turbine fuels. The measurements of the temperatures ...

8. A strategy for testing product conformance to geometric dimensioning & tolerancing standards
Topic: Energy
Published: 4/20/2012
Authors: Simon Paul Frechette, Bryan R Fischer
Abstract: Geometric Dimensioning and tolerance (GD&T) information is created as part of the design process. Today, that process is performed using computer-aided design systems, which generate 3D digital product models. GD&T is created and stored as an integra ...

9. Modeling Line Edge Roughness in Lamellar Block Copolymer Systems
Topic: Energy
Published: 3/21/2012
Authors: Paul Nathan Patrone, Gregg M Gallatin
Abstract: Block copolymers offer an appealing alternative to current lithographic techniques with regard to fabrication of the next generation micro- processors. However, if copolymers are to be useful on an industrial manufacturing scale, they must meet or e ...
