111. Measuring the Utility/Path Diversity Tradeoff in Multipath Protocols
Topic: Math
Published: 10/20/2009
Authors: Fern Y Hunt, Vladimir V Marbukh
Abstract: We derive a model of congestion control where the trade-off between utility and path diversity can be investigated. In a network where there can be multiple routes between locations, each source is assigned a route according to a random allocation s ...

112. Metrological Compatibility and Statistical Consistency
Topic: Math
Published: 9/5/2010
Authors: Raghu N Kacker, Ruediger Kessel, Klaus-Dieter Sommer, Xin Bian
Abstract: The traditional concept of consistency in multiple evaluations of the same measurand is statistical. The statistical view of consistency does not match the modern view of uncertainty in measurement; in particular, it does not apply to the results of ...

113. Minimum-Phase Calibration of Sampling Oscilloscopes
Topic: Math
Published: 8/15/2006
Authors: Andrew M Dienstfrey, Paul D Hale, Darryl A. Keenan, Tracy S. Clement, Dylan F Williams
Abstract: We describe an algorithm for determining the minimum phase of a linear time-invariant response function from its magnitude. The procedure is based on Kramers Kronig relations in combination with auxiliary direct measurements of the desired phase resp ...

114. Modeling Microstructures with OOF2
Topic: Math
Published: 9/1/2009
Authors: Andrew C.E. Reid, Rhonald Lua, R E Garcia, Valerie R. Coffman, Stephen Langer
Abstract: OOF2 is a program for computing the properties and behavior of material microstructures, beginning with an image of the microstructural geometry. OOF2 uses finite elements, but is designed to be used by materials scientists with little or no finite e ...

115. Modeling of Photochemical Reactions in a Focused Laser Beam
Series: Journal of Research (NIST JRES)
Topic: Math
Published: 7/1/2007
Authors: Fern Y Hunt, Adolfas Kastytis Gaigalas, Lili Wang
Abstract: This paper presents a mathematical model of photodegradation of fluorophores passing through a laser beam. The beam is focused on the sample and thus the power distribution of incident light is strongly dependent on spatial location while the fluorop ...

116. Modelling Type Ia Supernova Light Curves
Topic: Math
Published: 9/15/2010
Authors: Bert W Rust, Dianne M O'Leary, Katharine M Mullen
Abstract: Type Ia supernova light curves are characterized by a rapid rise from zero luminosity to a peak value, followed by a slower quasi-exponential decline. The rise and peak last for a few days, while the decline persists for many months. It is widely b ...

117. Moment-Preserving Modeling With Image Applications
Topic: Math
Published: 7/6/1998
Authors: Anastase Nakassis, Abdou Sleiman Youssef
Abstract: Linear least-square modeling is a powerful modeling approach. Optimal piece-wise constant modeling is an important special case. In this paper we will develop a piece-wise constant modeling method that preserves the regional means and regional fir ...

118. Multiresolution Representation of Urban Terrain By L^1^ Splines, L^2^ Splines, and Piecewise Planar Surfaces
Topic: Math
Published: 12/11/2000
Authors: J E Lavery, David E. Gilsinn
Abstract: Cubic L^d1^ and L^d2^ interpolating splines based on C^u1^ smooth piecewise cubic Sibson elements on a tensor-product grid are investigated. Computational tests were carried out for a 102.4 km area of Fort Hood, Texas represented by a 1025 x 1025 set ...

119. NIST Digital Library of Mathematical Functions
Topic: Math
Published: 5/1/2003
Author: Daniel W Lozier
Abstract: NIST (formerly, National Bureau of Standards) has started an ambitious project that aims to produce a successor to Abramowitz and Stegun's {\em Handbook of Mathematical Functions}, published by the National Bureau of Standards in 1964 and reprinted b ...

120. On Feedback Functions of Maximum Length Nonlinear Feedback Shift Registers
Topic: Math
Published: 8/2/2010
Authors: Cagdas Calik, Meltem Sonmez Turan, Ferruh Ozbudak
Abstract: Feedback shift registers are basic building blocks for many cryptographic primitives. Due to the insecurities of Linear Feedback Shift Register (LFSR) based systems, the use of Nonlinear Feedback Shift Registers (NFSRs) became more popular. In this w ...
