Towards Cross-Layer Optimization of Virtualized Radio Access Networks

August 15, 2019
Author(s)
Vladimir Marbukh, Kamran Sayrafian, Behnam Rouzbehani, Luis Correia
This paper proposes an approach to cross-layer optimization of virtualized Radio Access Network resources in future mobile communications. Assuming that the Virtual Network Operators (VNOs) guarantee contracted Service Level Agreements (SLAs) with the

TOWARDS EFFICIENT THERMAL SIMULATION OF POWDER BED FUSION ON PATH LEVEL

August 15, 2019
Author(s)
Paul W. Witherell
As a widely used additive manufacturing (AM) technology to produce metallic parts, powder bed fusion (PBF) is driven by a moving heat source. Thermal simulation is a critical tool to understand the mappings between manufacturing parameters (e.g. laser

A Modelling Framework for Householder Decision-Making for Wildfire Emergencies

August 14, 2019
Author(s)
Ruggiero Lovreglio, Erica D. Kuligowski, Steve Gwynne, Ken Strahan
The occurrence of wildfire threats has dramatically increased in the last few decades creating serious challenges for hundreds of thousands of communities around the world. Understanding the physical and social dynamics characterizing wildfires is

The Evolution of Cranfield

August 14, 2019
Author(s)
Ellen Voorhees
This chapter examines how the test collection paradigm, the dominant evaluation methodology in information retrieval, has been adapted to meet the changing requirements for information retrieval research in the era of community evaluation conferences such

AMAP Review: Biological Effects from Contaminants on Arctic Wildlife and Fish

August 13, 2019
Author(s)
Rune Dietz, Robert Letcher, Colleen E. Bryan Sallee, John Kucklick, Stacy Schuur, Jean-Pierre Desforges, Igor Eulaers, Bjorn Munro Jenssen, Melissa McKinney, Christian Sonne, Niladri Basu, Simon Wilson, Sara Pedro, Jenny Bytingsvik, Garry Stenson, Anuschka Polder, Joshua T. Ackerman, Collin A. Eagles-Smith, Mark P. Herzog, Alex Hartman, Sarah Peterson, Allyson Jackson, Birgit Braune, Derek Muir, Frank Riget, Milton Levin, Anders Bignert, Maria Dam, Marlene Evans, Magali Houde, Katrin S. Hoydal
Since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of the exposure to persistent organic pollutants (POPs) classified as organohalogen compounds (OHCs) in Arctic biota there has been a considerable number

Ramsey-Borde Matter-Wave Interferometry for Laser Frequency Stabilization at 10 -16 Frequency Instability and Below

August 13, 2019
Author(s)
Judith B. Olson, Todd Sheerin, Holly Leopardi, Roger C. Brown, Richard W. Fox, Rick Stoner, Tara M. Fortier, Christopher W. Oates, Andrew D. Ludlow
We demonstrate Ramsey-Borde (RB) atom interferometry for high performance laser stabilization with fractional frequency instability −16 for timescales between 10 and 1000s. The RB spectroscopy laser interrogates two counterpropagating 40Ca beams on the 1S

Understanding the Impact of Drug Background Levels in Forensic Laboratories

August 13, 2019
Author(s)
Edward Sisco, Marcela N. Najarro, Amber Burns, Robert Kirkby
As drugs become increasingly potent and analytical instrumentation becomes more sensitive, the need to understand and monitor drug background levels is becoming imperative. Background monitoring is commonplace in many other industries but has been largely

Users Guide to Type277 Loosely Coupled Integration of TRNSYS with Java

August 13, 2019
Author(s)
Farhad Omar
The purpose of this document is to provide instructions for using a newly developed TRNSYS component (Type277). Type277 enables the loosely-coupled integration of a TRNSYS model with Java software environments using socket communication. The bi-directional

Terahertz-Rate Kerr-Microresonator Optical Clockwork

August 12, 2019
Author(s)
Tara E. Drake, Travis Briles, Daryl T. Spencer II, Jordan R. Stone, David R. Carlson, Daniel D. Hickstein, Qing Li, Daron A. Westly, Kartik A. Srinivasan, Scott A. Diddams, Scott B. Papp
Kerr microresonators generate interesting and useful fundamental states of electromagnetic radiation through nonlinear interactions of continuous-wave (CW) laser light. When implemented with photonic-integration techniques, functional devices with low

SCAP Composer: A DITA Open Toolkit Plug-in for Packaging Security Content

August 9, 2019
Author(s)
Joshua Lubell
The Security Content Automation Protocol (SCAP) schema for source data stream collections standardizes the requirements for packaging Extensible Markup Language (XML) security content into bundles for easy deployment. SCAP bundles must be self-contained

Standardization of I-124 by three liquid scintillation-based methods

August 9, 2019
Author(s)
Denis E. Bergeron, Leticia S. Pibida, Brian E. Zimmerman, Jeffrey T. Cessna, Ryan P. Fitzgerald
A solution of 124I was standardized for activity by 4πβ(LS)-γ(NaI) live-timed anticoincidence (LTAC) counting, with confirmatory measurements by triple-to-double coincidence ratio (TDCR) and CIEMAT-NIST efficiency tracing (CNET) liquid scintillation

Disentangling Polymer Network and Hydration Water Dynamics in Polyhydroxyethyl Methacrylate Physical and Chemical Hydrogels

August 8, 2019
Author(s)
Daria Noferini, Antonio Faraone, Marta Rossi, Eugene Mamontov, Emiliano Fratini, Piero Baglioni
Cross-linker nature and water content may impact the microscopic dynamics of hydrogels components, and thus their properties in applications such as drug-delivery. To investigate this aspect, we used quasi-elastic neutron scattering with contrast variation
