Predicting the In-Service Performance of Materials Exposed to Outdoor Weathering

May 12, 2010
Author(s)
Christopher C. White, Kar T. Tan, Donald L. Hunston
Test methods were developed to duplicate the failure modes that occur to sealants during exposure in structures. The methods used a systematic approach to identify independent and synergistic effects of various aging factors on the durability of sealants

STRUCTURAL RESPONSE OF WTC 7 FLOOR SYSTEMS TO FIRE

May 12, 2010
Author(s)
Therese P. McAllister
The WTC 7 investigation by the National Institute of Standards and Technology (NIST) identified several factors that alone, or in combination, led to fire-induced failures of the floors, and subsequently, total collapse of the 47-story WTC 7 building. A

The NIST Handbook of Mathematical Functions

May 12, 2010
Author(s)
Frank W. Olver, Daniel W. Lozier, Ronald Boisvert, Charles W. Clark
The NIST Handbook of Mathematical Functions supplies validated reference information in 36 chapters on a wide selection of important mathematical functions, covering the properties necessary for their use in scientific applications, together with general

Synthesis and properties of turbostratically disordered,ultrathin WSe2 films

May 11, 2010
Author(s)
Ngoc Nguyen, Polly Berseth, Qiyin Lin, Catalin Chiritescu, D.G. Cahill, Anastassios Mavrokefalos, Li Shi, Paul Zschack, Michael D. Anderson, Ian M. Anderson, David C. Johnson
Turbostratically disordered tungsten diselenide (WSe2) thin films with as few as two c-axis-oriented (basal plane) structural units were synthesized from modulated elemental reactants. By varying the number of elemental W-Se bilayers deposited, the

Test Suite for Building Energy Analysis of Conceptual Spatial Layout

May 11, 2010
Author(s)
Kenway K. Chen, Robert R. Lipman, Mark E. Palmer
This report documents a test suite for validation and conformance testing in support of the interoperability among building design and energy analysis applications. The objectives of this test suite are to: provide to software vendors test cases to

FRVT 2006: Quo Vidas Face Quality

May 10, 2010
Author(s)
P J. Phillips, J. R. Beveridge, Geof H. Givens, Bruce A. Draper, David Bolme, Yui M. Lui
This paper summarizes a study of how three state-of-the-art algorithms from the Face Recognition Vendor Test 2006 (FRVT 2006) are effected by factors related to face images and the people being recognized. The recognition scenario compares highly

Measuring and improving U.S. construction productivity

May 10, 2010
Author(s)
Robert E. Chapman, David T. Butry, Allison L. Huang
Although the construction industry is a major component of the U.S. economy, it has experienced a prolonged period of decline in productivity. Due to the critical lack of measurement methods, however, the magnitude of the productivity problem in the U.S

Multiple Encounter Dataset I (MEDS-I)

May 10, 2010
Author(s)
Craig I. Watson
In December, 2008, the FBI provided MITRE with an extract of submissions of deceased persons. The submissions contain face images of subjects with multiple encounters over time. The type 10 records (face and SMT) are mostly frontal or near frontal face

Shell-dependent Blinking of CdSe-Based Core/Shell Nanocrystals

May 10, 2010
Author(s)
Seung Koo Shin, Bonghwan Chon, Sung Jun Lim, Wonjung Kim, Hyeong G. Kang, Taiha Joo, Jeeseong C. Hwang
Blinking of zinc-blende CdSe-based core/shell nanocrystals are studied as a function of shell materials. CdSe/ZnS, CdSe/ZnSe/ZnS, and CdSe/CdS/ZnS core/shell nanocrystals are prepared by epitaxial growth of two-to-six monolayers (MLs) of shell materials
