Quasiuniversal Excess Entropy Scaling in Binary Supercooled Liquids

August 27, 2020
Author(s)
Ian H. Bell, Jeppe Dyre, Trond Ingebrigtsen
Transport coefficients, such as viscosity or diffusion coefficient, show significant dependence on density or temperature near the glass transition. Although several theories have been proposed for explaining this dynamical slowdown, the origin remains to

Heat capacity and decomposition of rimantadine hydrochloride

January 30, 2020
Author(s)
Ala Bazyleva, Yauheni Paulechka, Dzmitry H. Zaitsau, Andrey V. Blokhin, Gennady J. Kabo
Heat capacities of antiviral drug rimantadine hydrochloride in the crystalline state were measured by adiabatic calorimetry and differential scanning calorimetry in the temperature range from (7 to 453) K. A broad low-enthalpy solid-state phase anomaly was

Characterization of the internal translation initiation region in monoclonal antibodies expressed in Escherichia coli

October 11, 2019
Author(s)
Erik M. Leith, William Brad O'Dell, Na Ke, Colleen McClung, Mehmet Berkmen, Christina Bergonzo, Robert G. Brinson, Zvi Kelman
Monoclonal antibodies (mAbs) represent an important platform for the development of biotherapeutic products. While most mAbs are produced in mammalian cells, there are several examples of mAbs made in Escherichia coli, including therapeutic fragments. When

Towards Operational Use of Unit Manufacturing Process Models

July 25, 2019
Author(s)
Amogh Kulkarni, William Z. Bernstein, David Lechevalier, Daniel Balasubramanian, Gabor Karsai, Peter O. Denno
Unit Manufacturing Processes (UMP) are models that capture succinct definitions of individual manufacturing steps in a manufacturing system. They are used to facilitate model composition and reuse. However, mainly due to their textual nature, they are

Capture of Highly Charged Ions in a Pseudo-Hyperbolic Paul Trap

July 12, 2019
Author(s)
Joan M. Dreiling, Aung Naing, Joseph Tan, Joshua Hanson, Shannon Hoogerheide, Samuel Brewer
The confinement of ions in a radio-frequency (RF) trap (also known as a Paul trap) has proven to be advantageous in many applications. Typically, singly- or few-times-ionized atoms can be created in situ within the ion trap. Highly charged ions, on the

Optimization of Air-to-Refrigerant Evaporator with Low-GWP Refrigerants

June 23, 2019
Author(s)
Piotr A. Domanski
An analytical evaluation of the performance of low-GWP refrigerants in a finned-tube evaporator used for residential cooling applications will be presented. The study employed an evolutionary-computation optimization module to examine the effect of a

BowTie - A deep learning feedforward neural network for sentiment analysis

April 22, 2019
Author(s)
Apostol T. Vassilev
How to model and encode the semantics of human-written text and select the type of neural network to process it with are not settled issues in sentiment analysis. Accuracy and transferability are critical issues in machine learning in general. These

Generating Domain Terminologies using Root- and Rule-Based Terms

December 21, 2018
Author(s)
Talapady N. Bhat, John T. Elliott, Ursula R. Kattner, Carelyn E. Campbell, Eswaran Subrahmanian, Ram D. Sriram, Jacob Collard, Monarch Ira
Motivated by the need for exible, intuitive, reusable, and normalized ter- minology for the semantic web, we present a general approach for generat- ing sets of such terminologies from nat- ural language documents. The terms that this approach generates

The Costs and Benefits of Advanced Maintenance in Manufacturing

April 25, 2018
Author(s)
Douglas Thomas
The manufacturing atmosphere is continually changing with new technologies and standards being swiftly developed. Firms create competitive advantages using their knowledge, skills, supply chains, and processes to create superior products at lower prices

A Layered and Aggregated Queuing Network Simulator for Detection of Abnormalities

December 3, 2017
Author(s)
Junfei Xie, Chenyan He, Yan Wan, Kevin L. Mills, Christopher E. Dabrowski
Driven by the needs to monitor, detect, and prevent catastrophic failures for complex information systems in real-time, we develop in this paper a discrete-time queuing network simulator. The dynamic model for the simulator abstracts network dynamics by

Effect of the Additive Manufacturing Process on Cutting Forces in Hybrid Manufacturing

November 3, 2017
Author(s)
Michael Gomez, Andrew Honeycutt, Jarred C. Heigel, Tony Schmitz
Powder bed fusion (PBF) enables metal components with complex geometries to be made via additive manufacturing (AM). Disadvantages of AM are rougher surface finish and lower achievable dimensional tolerances compared to computer numerically-controlled (CNC

Scaling Methods for Dynamic Building System Simulation in an HVACSIM+ Environment

August 9, 2017
Author(s)
Zhelun Chen, Jin Wen, Anthony Kearsley, Amanda Pertzborn
A robust and efficient nonlinear algebraic and differential equations solver is increasingly essential as the scale of dynamic building system simulation grows larger and the models employed become more complex. There are many factors affecting the

Mobile Manipulator Performance Measurement Data

June 27, 2017
Author(s)
Roger V. Bostelman, YaShian Li-Baboud, Steven Legowik, Tsai H. Hong, Sebti Foufou
The National Institute of Standards and Technology, Intelligent Systems Division has collected data detailing the performance measurement of a mobile manipulator, i.e., an automatic guided vehicle (AGV) with onboard robot arm from two different

Void-based Assembly of Colloidal Crystals

June 1, 2017
Author(s)
Nathan Mahynski, Lorenzo Rovigatti, Christos Likos, Athanassios Panagiotopoulos
We have used computer simulations to reveal how colloidal crystals may be assembled by engineering the shape and charge of polymeric additives, which act as structure-directing agents (SDAs). Using these agents, only a single desired polymorph may be

Towards Estimating the Uncertainty Associated with 3D Geometry Reconstructions from Medical Image Data

May 23, 2016
Author(s)
Zachary H. Levine, Karim O. Genc, Stephen M. Luke, Todd Pietiela, Ross T. Cotton, Benjamin Ache, Phillipe G. Young, Marc Horner, Kevin C. Townsand
3D image based modeling for visualization, physics-based simulation or additive manufacturing, is becoming more common within R&D labs in academia, government and commercial industry. Computed Tomography (CT) is a common imaging modality used to obtain the

Phase Behavior of Poly(3-hexylthiophene-2,5-diyl)

March 8, 2016
Author(s)
Chad R. Snyder, Enrique Gomez
The phase behavior of many conjugated polymers is rich but not yet fully explored. Stiff chain conformations and planar ring-like structures can promote both crystalline and liquid crystalline phases. Recent computational efforts that rely on atomistic and
