Uncertainty Analysis for Virtual Cement Measurement
Virtual measurements are the outputs of well-defined mathematical models based on theoretical principles and simulation algorithms. The VCCTL (Virtual Cement and Concrete Testing Laboratory) is a software system built by the Material and Construction
Guide to Computer Security Log Management
The National Institute of Standards and Technology (NIST) developed this document in furtherance of its statutory responsibilities under the Federal Information security Management Act (FISMA) of 2002, Public Law 107-347. This publication seeks to assist

Effective Link Triggers to Improve Handover Performance
Effective link layer triggering is key in order to enable fast and reliable handover across different access networks. In this paper, we investigate the use of signal strength as part of the trigger mechanism. We propose an analytical model to estimate the
Investigating Global Behavior in Computing Grids
This paper presents an executable model of grid computing systems and a measurement approach, based on multidimensional analysis, to understand global behavior in a complex system. Specifically, we investigate effects of spoofing attacks on the scheduling
Guidelines for Media Sanitization
Information systems capture, process, and store information using a wide variety of media. This information is located not only on the intended storage media but also on devices used to create, process, or transmit this information. These media may require
Guide to Integrating Forensic Techniques into Incident Response
This publication is intended to help organizations in investigating computer security incidents and troubleshooting some information technology (IT) operational problems by providing practical guidance on performing computer and network forensics. The

Multiple Description Video Coding Over Multiple Path Routing Networks
This paper presents a multiple description (MD) video-coding scheme, which uses interlaced high signal to noise ratio (H-SNR) and low signal to noise ratio (L-SNR) coded frames to produce two bit-streams. At the decoder, when both bit-streams are received
Polarization Recovery and Auto-compensation in Quantum Key Distribution Network
A Quantum Key Distribution (QKD) network can allow multi-user communication via secure key. Moreover, by actively switching communication nodes, one can achieve high key transmission rate for the selected nodes. However, the polarization properties of
Multiple Description Video Coding over Multiple Path Routing Networks
This paper presents a multiple description (MD) video-coding scheme, which uses interlaced high signal to noise ratio (H-SNR) and low signal to noise ratio (L-SNR) coded frames to produce two bit-streams. At the decoder, when both bit-streams are received
Effects of Using an Unshielded Cable as a Reference Standard in Cable Shielding Measurements, or, Do You Really Want to Base Your Results on a Naked Cable?
We examine the effects of using an unshielded cable as a reference standard for the evaluation of the high-frequency shielding effectiveness of cables. We placed an unshielded cable (wire) in five different configurations in our reverberation chamber. In
Demonstration of an Active Quantum Key Distribution Network
We previously demonstrated a high speed, point to point, quantum key distribution (QKD) system with polariztion coding over a fiber link, in which the resulting cryptographic keys were used for one-time pad encryption of real time video signals. In this
Concrete Multiplicative Complexity of Symmetric Functions
The multiplicative complexity of a Boolean function f is defined as the minimum number of binary conjunction (AND) gates required to construct a circuit representing f, when only exclusive-or, conjunction and negation gates may be used. This article

Intelligent Plane as a Mapping Mechanism for User Level Performance Optimization: A Case of Reliable Services over Unreliable Network
This paper proposes a framework for balancing competing user level requirements by resolving the corresponding trade-offs in a distributed system with limited resources. Assuming that each user's preferences can be characterized by some utility function
Multi-Path Multi-Channel Routing Protocol
In this paper we present a DSR-based multi-path Routing protocol, which has been developed for transmission of Multiple Description Coded (MDC) packets in wireless ad-hoc network environments. The protocol is designed to eliminate co-channel interference
5th Annual PKI R&D Workshop "Making PKI Easy to Use" Proceedings
NIST hosted the fifth annual Public Key Infrastructure (PKI) Research Workshop on April 4-6, 2006. The two and a half day event brought together PKI experts from academia, industry, and government to explore the remaining challenges in deploying public key
