An On-Off Source Model for Improved Buffer Statistics Modeling in TCP Fluid Approximation Models.
We propose using an on-off fluid source model for queuing statistics under TCP. This model was originally introduced to model queuing statistics of ATM multiplexers by D.Anick, D.Mitra and M.M.Sondhi. A good approximation for packet loss probability is
View subspaces for indexing and retrieval of 3D models
View-based indexing schemes for 3D object retrieval is gaining popularity since they provide good retrieval results. These schemes are coherent with the theory that humans recognize objects based on their 2D appearances. The view-based techniques also
Common Logic (CL) is an ISO standard that specifies a family of knowledge representation languages. The function of modules within CL is to support local context with a local domains of discourse. Modules play a crucial role since they enable users to
Recommendation for Block Cipher Modes of Operation: The XTS-AES Mode for Confidentiality on Storage Devices
This document approves the XTS-AES mode of the AES algorithm by reference to IEEE Std 1619-2007, subject to one additional requirement, as an option for protecting the confidentiality of data on storage devices. The mode does not provide authentication of
Complex Systems Program Activities Summary, Fiscal Years 2007-2008

Cryptographic Key Management Workshop Summary - June 8-9, 2009
On June 8 and 9, 2009, NIST held a Cryptographic Key Management (CKM) Workshop at its Gaithersburg, Maryland, campus that attracted approximately 80 people attending the workshop in person, with another 75 participating through video conferencing, and an
A Hybrid Frame Concealment Algorithm for H.264/AVC
In packet-based video transmissions, packets loss due to channel errors may result in the loss of the whole video frame. Recently, many error concealment algorithms have been proposed in order to combat channel errors, however most of the existing
Proceedings of the Privilege Management Workshop, September 1-3, 2009
Privilege management is large and complex, often the source of heated debate and opinion, and fraught with widely-understood, yet ill-defined terminology and concepts. The National Institute of Standards and Technology (NIST) and the National Security
This Editor In Chief's (EIC) message is expected to appear in the January, 2010 issue of the IEEE Transactions on CAS for Video Technology (TCSVT). The editorial team will be under the leadership of the new EIC for a period of two years.
Recommendation for Key Management - Part 3: Application-Specific Key Management Guidance
[Superseded by: SP 800-57 Part 3 Rev. 1 (January 2015): http://www.nist.gov/manuscript-publication-search.cfm?pub_id=917445 ] Special Publication 800-57 provides cryptographic key management guidance. It consists of three parts. Part 1 provides general
Transistors have been made from single molecules, where the flow of electrons is controlled by modulating the energy of the molecular orbitals. Insight from such systems could aid the development of future electronic devices.
Model of magnetic impurities within the Josephson junction of a phase qubita
We consider a superconducting phase qubit consisting of a monocrystalline sapphire Josephson junction with symmetry axis perpendicular to the junction interfaces. Via the London gauge we present a theoretical model of Fe3+ magnetic impurities within the
There is a growing recognition within the visual analytics community that interaction and inquiry are inextricable. It is through the interactive manipulation of a visual interface the analytic discourse that knowledge is constructed, tested, refined, and

Self-Deployment Algorithms for Coverage Problem in a Network of Mobile Sensors with Unidentical Sensing Range
In this paper, efficient sensor deployment algorithms are proposed to improve the coverage area in the target field. The proposed algorithms calculate the position of the sensors iteratively based on the existing coverage holes in the target field. The
Indifferentiability Characterization of Hash Functions and Optimal Bounds of Popular Domain Extensions
Understanding what construction strategy has a chance to be a good hash function is extremely important. Nowadays it is getting more importance due to current SHA3 competition which is intended to make a standard for hash functions. In TCC 04, Maurer et al
SER Performance Analysis for Physical Layer Network Coding over AWGN Channel
While original network coding is proposed over data link layer, recent work suggests that it can also be implemented on physical layer. In fact it is more natural for wireless networks because of its omnidirectional transmission. In this paper, we
