31. Theory and Algorithms for Weighted Total Least-Squares Fitting of Lines, Planes, and Parallel Planes to Support Tolerancing Standards
Topic: Energy
Published: 8/16/2013
Authors: Craig M Shakarji, Vijay Srinivasan
Abstract: We present the theory and algorithms for fitting a line, a plane, two parallel planes (corresponding to a slot or a slab) or many parallel planes in a total (orthogonal) least-squares sense to coordinate data that is weighted. Each of these problems ...

32. Soft X-ray Characterization of DSA Block Copolymers
Topic: Energy
Published: 8/12/2013
Authors: Daniel Franklin Sunday, Wen-Li Wu, Regis J Kline

33. 3D X-ray Metrology for Block Copolymer Lithography Line-Space Patterns
Topic: Energy
Published: 7/15/2013
Authors: Daniel Franklin Sunday, Matthew R. Hammond, Chengqing C. Wang, Wen-Li Wu, Regis J Kline, Gila E. Stein
Abstract: We report on the development of a new measurement method, resonant critical-dimension small-angle x-ray scattering (CD-SAXS), for the characterization of the buried structure of block copolymers (BCP) used in directed self assembly (DSA). We use reso ...

34. Absolute spectral responsivity measurements of solar cells by a hybrid optical technique
Topic: Energy
Published: 7/15/2013
Authors: Behrang H Hamadani, John F Roller, Brian P Dougherty, Fiona Persaud, Howard W Yoon
Abstract: An irradiance mode, absolute differential spectral response measurement system for solar cells is presented. The system is based on combining the monochromator-based approach of determining the power mode spectral responsivity of cells with an LED-b ...

35. Frameworks and Data Initiatives for Smart Grid and other Cyber-Physical Systems
Topic: Energy
Published: 7/1/2013
Author: David A Wollman
Abstract: I describe the NIST smart grid framework and its applicability as a model for organizational efforts to advance cyber-physical systems, and provide an overview of smart grid data initiatives.

36. 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 ...

37. 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 ...

38. A focused super-continuum solar simulator for illuminated solar cell microscopy
Topic: Energy
Published: 5/12/2013
Author: Tasshi Dennis
Abstract: The design and application of a novel, focused solar simulator based on a high-power, super-continuum laser is described. We used the simulator to create micrometer-scale spatial maps of full-spectrum optical beam induced current (FS-OBIC) in sam ...

39. Towards Demand Response Measurement and Verification Standards
Topic: Energy
Published: 5/1/2013
Authors: David G Holmberg, David Hardin, Ed Koch
Abstract: The value and impact of demand response (DR) at grid-scale depends upon the widespread and active participation of a diverse customer base. The level of participation by customers is impacted by financial compensation and return-on-investment. The ro ...

40. 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 ...
