Author(s)
Richard Ayers, Sam Brothers, Wayne Jansen
Mobile device forensics is the science of recovering digital evidence from a mobile device under forensically sound conditions using accepted methods. Mobile device forensics is an evolving specialty in the field of digital forensics. This guide attempts

LTE Physical Layer Performance Analysis

May 15, 2014
Author(s)
Wen-Bin Yang, Michael R. Souryal
In this report, we present results of a physical layer performance study for all MCSs (from MCS0 to MCS28) in terms of block error rate (BLER) and spectral efficiency. The results are obtained by using the Steepest Ascent LTE toolbox for MATLAB which

Non-contact Conductance Measurement of Nanosize Objects using Reasonant Cavity

May 15, 2014
Author(s)
Jan Obrzut, Nathan D. Orloff, Oleg A. Kirillov
A cavity perturbation method is used to determine conductance of small volume nano-carbon materials. These are the building blocks of nanostructured materials and devices, and therefore their electrical characteristics are important in the materials

Standards in Biothermodynamics

May 15, 2014
Author(s)
Robert N. Goldberg
The field of biothermodynamics encompasses physical property measurements on biochemical and biological systems. This chapter reviews the status of standards documents that are pertinent to biothermodynamics as well as recommendations that have been made

A Facile Route to the Synthesis of Monodisperse Nanoscale Liposomes Using 3D Microfluidic Hydrodynamic Focusing in a Concentric Capillary Array

May 14, 2014
Author(s)
Wyatt N. Vreeland, Renee R. Hood, Don L. DeVoe, Francisco J. Atencia, Donna M. Omiatek
A novel microscale device has been developed to enable the one-step continuous flow assembly of monodisperse nanoscale liposomes using three-dimensional microfluidic hydrodynamic focusing (3D-MHF) in a radially symmetric capillary array. The 3D-MHF flow

Effect of Interfacial Octahedral Behavior in Ultrathin Manganite Films

May 14, 2014
Author(s)
E. J. Moon, P. V. Balachandran, Brian Kirby, D.J. Keavney, R.J. Sichel-Tissot, C. M. Schleputz, E. Karapetrova, X. M. Cheng, James M. Rondinelli, S. J. May
We investigate structural coupling of the MnO 6 octahedra across a film/substrate interface and the resultant changes of the physical properties of ultrathin La 2/3}Sr 1/3}MnO 3 (LSMO) films. In order to isolate the effect of interfacial MnO 6 octahedral

Packing density of rigid aggregates is independent of scale

May 14, 2014
Author(s)
Christopher D. Zangmeister, James G. Radney, Michael R. Zachariah
Large planetary seedlings, comets, microscale pharmaceuticals, and nanoscale soot particles are made from rigid, aggregated subunits that are compacted under low compression into larger structures spanning over 10 orders of magnitude in dimensional space

Precise Latency Measurement of Unidirectional-Data-Flow Network Equipment

May 14, 2014
Author(s)
I-Chun Chao, Kang B. Lee, Frederick M. Proctor, Chien-Chung Shen, Fan-Ren Chang
In regards to network performance measurements, many timing indices, such as latency, jitter, and one-way delay (OWD), are getting more attention because real-time applications and needs are pushing higher network capabilities. Data latency in a network

Reference Materials 8096 and 8097 - The MEMS 5-in-1 RMs: Homogeneous and Stable

May 14, 2014
Author(s)
Janet M. Cassard, Jon C. Geist, John A. Kramar
The NIST Microelectromechanical Systems (MEMS) 5-in-1 Reference Materials (RMs) were developed to assist users in validating their use of five documentary standard test methods. A Reference Material can be defined as a material whose property values are

A CW calibrated laser pulse energy meter for the range 1 pJ to 100mJ

May 13, 2014
Author(s)
Malcolm G. White, Rodney W. Leonhardt, David J. Livigni, John H. Lehman
We describe the use of a silicon photodiode trap detector and digital storage oscilloscope as an absolute laser pulse energy meter, capable of repetition rates of 85 Hz and 5% uncertainty (k = 2). The maximum repetition rate is limited by the decay time of

Metrology for 3D Integration

May 13, 2014

Richard A. Allen, Victor H. Vartanian, David T. Read, Winthrop A. Baylies
Three-dimensional stacked integrated circuit (3DS-IC) fabrication requires complex technologies such as high-aspect ratio through- silicon vias (TSVs), wafer thinning, thin wafer handling and processing, and bonding of thin wafers with complex patterned

Small and Medium-size Business Information Security Outreach Program

May 13, 2014
Author(s)
Richard L. Kissel, Kim Quill, Chris Johnson
Small and medium-sized businesses (SMBs) represent 99.7 percent of all U.S. employers and are an important segment of the U.S. economy. These organizations, totaling more than 28.2 million, create over 60 percent of all new U.S. private-sector jobs and

A single photon transistor based on superconducting systems
