Standard Data-Based Predictive Modeling for Power Consumption in Turning Machining

February 26, 2018
Author(s)
Seungjun Shin, Jungyub Woo, Sudarsan Rachuri, Prita Meilanitasari
In the metal cutting industry, power consumption is an important metric in the analysis of energy efficiency since it relates to energy consumption of machine tools. Much of the research has developed predictive models that correlate process planning

New Connections for Enhancing Robustness of Precast Concrete Frame Structures

February 24, 2018
Author(s)
Travis E. Thonstad, Yihai Bao, Jonathan M. Weigand, Joseph A. Main, Hai S. Lew
A recent experimental and computational study of two precast concrete moment-frame assemblies under a column removal scenario revealed vulnerabilities in the moment connections arising from (a) local bending of reinforcing bars due eccentricity in the

Band Jahn-Teller Structural Phase Transition in Y 2 In

February 23, 2018
Author(s)
E. Svanidze, C. Georgen, Qingzhen Huang, J. M. Santiago, Jeffrey W. Lynn, E. Morosan
The number of paramagnetic materials that undergo a structural phase transition is rather small, which ca perhaps explain the limited understanding of the band Jahn-Teller mechanism responsible for the effect. Here we present a structural phase transition

Evaluation of Cloud Computing Services Based on NIST SP 800-145

February 23, 2018
Author(s)
Eric D. Simmon
This document provides clarification for qualifying a given computing capability as a cloud service by determining if it aligns with the NIST definition of cloud computing; and for categorizing a cloud service according to the most appropriate service

Large Field of View Quantitative Phase Imaging of Induced Pluripotent Stem Cells and Optical Pathlength Reference Materials

February 23, 2018
Author(s)
Edward J. Kwee, Alexander W. Peterson, Jeffrey R. Stinson, Michael W. Halter, Liya Yu, Michael P. Majurski, Joe Chalfoun, Peter Bajcsy, John T. Elliott
Induced pluripotent stem cells (iPSCs) are reprogrammed cells that can have heterogeneous biological potential. Quality assurance metrics of reprogrammed iPSCs will be critical to ensure reliable use in cell therapies and personalized diagnostic tests. We

NIST Time and Frequency Bulletin

February 23, 2018
Author(s)
Kathryn R. Stephenson
The Time and Frequency Bulletin provides information on performance of time scales and a variety of broadcasts (and related information) to users of the NIST services.

PSCR Highly Mobile Deployable Networks R&D Summit Report

February 23, 2018
Author(s)
Maxwell K. Maurice, Samuel L. Ray, Marc Leh
The Public Safety Communications Research Program (PSCR) convened over 85 stakeholders at the Department of Commerce Boulder, CO campus to discuss the opportunities and challenges facing public safety’s expanded use of next-generation deployable systems

Weak and Strong Gels and the Emergence of the Amorphous Solid State

February 23, 2018
Author(s)
Jack F. Douglas
Gels are amorphous solids whose macroscopic viscoelastic response derives from contraints in the material that serve to localize the constituent molecules or particles about their average positions in space. These contraints may either be local in nature

A Non-Invasive Method to Directly Quantify Surface Heterogeneity of Porous Materials

February 22, 2018
Author(s)
Wei-Shan NMN Chiang, Daniel Georgi, Taner Yildirim, Jin-hong Chen, Yun Liu
Many porous materials have widely differing pore surface properties because the matrix materials forming the pores are heterogeneous at microscopic levels resulting in different adsorption/desorption behaviors and storage capacity of guest molecules in

Blade Coating Aligned, High-Performance, Semiconducting-Polymer Transistors

February 22, 2018
Author(s)
Lee J. Richter, Hyun W. Ro, Regis J. Kline, Daniel A. Fischer, Dean M. DeLongchamp, Lars Thomsen, Christopher McNeil, Dawei Wu, Maria Kaplan, Eliot H. Gann
Recent demonstration of mobilities in excess of 10 cm2V-1s-1 have energized research in solution deposition of polymers for thin film transistor applications. Due to the lamella motif of most soluble, semiconducting polymers, the local mobility is

Implementations of the Tennessee Eastman Process in Modelica

February 22, 2018
Author(s)
Carla Martin-Villalba, Alfonso Urquia, Guodong Shao
The Tennessee Eastman process is a typical industrial process that consists of five main process units: a two-phase reactor where an exothermic reaction occurs, a separator, a stripper, a compressor, and a mixer. This is a nonlinear open-loop unstable

Structure, Nanomechanics and Dynamics of Dispersed Surfactant-Free Clay Nanocomposite Films

February 22, 2018
Author(s)
Xiao Zhang, Jing Zhao, Chad R. Snyder, Abdullah Al-Enizi, Ahmed Eltazahry, Alamgir Karim
Using additives to tailor the performance of polymeric materials is perhaps one of the most important aspects for producing materials of advanced applications. The exploitation of nanoparticle dispersion strategies have been broadly investigated for tuning

Topological Rigidification of Flexible Polymers in Solution

February 22, 2018
Author(s)
Jack F. Douglas, Fernando Vargas-Lara
We use molecular dynamic simulations on a coarse-grained model for flexible polymers in solution to study how molecular topology affects the intrinsic rigidity of polymeric chains. In particular, we study how polymeric "topological complexity", defined by

What Does the Tg of Thin Polymer Films Really Tell Us?

February 22, 2018
Author(s)
Wengang Zhang, Francis W. Starr, Jack F. Douglas
The disparate results for Tg shifts in ultra-thin polymer films with the same film thickness, substrate, and chemistry raises the question of whether Tg is a useful way to characterize thin films. Underlying many Tg measurements is the assumption that Tg

"The devil's in the detail": Release of an expanded, enhanced and dynamically revised forensic STR Sequence Guide

February 21, 2018
Author(s)
Christopher Phillips, Katherine Gettings, Jonathan King, David Ballard, Martin Bodner, Lisa Borsuk, Walther Parson
The STR sequence template file published in 2016 as part of the considerations from the DNA Commission of theInternational Society for Forensic Genetics on minimal STR sequence nomenclature requirements, has been comprehensively revised and audited using
