81. Modeling queuing dynamics of TCP: a simple model and its empirical validation.
Topic: Modeling
Published: 5/6/2011
Authors: Daniel Ilya Genin, Anastase Nakassis
Abstract: Understanding queuing dynamics of TCP is important for correct router buffer sizing as well as for optimizing the performance of the TCP protocol itself. However, modeling of buffer content dynamics under TCP has received relatively little attent ...

82. Modelling Type Ia Supernova Light Curves
Topic: Modeling
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 ...

83. Multiresolution Representation of Urban Terrain By L^1^ Splines, L^2^ Splines, and Piecewise Planar Surfaces
Topic: Modeling
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 ...

84. Multiscale Model of Germanium Quantum Dots in Silicon
Topic: Modeling
Published: 3/1/2007
Authors: David Thomas Read, Vinod K Tewary
Abstract: Atomic displacements, strains and strain energies in the neighborhood of near-spherical, coherent germanium ¿quantum dots¿ (QD) in crystalline silicon and near a {001} Si surface have been predicted by multiscale modeling, using a combination of clas ...

85. NON-RIGID 3D SHAPE RETRIEVAL USING MULTIDIMENSIONAL SCALING AND BAG-OF-FEATURES
Topic: Modeling
Published: 12/20/2010
Authors: Zhouhui Lian, Afzal A Godil
Abstract: Matching non-rigid shapes is a challenging research field in content-based 3D object retrieval. In this paper, we present an image-based method to effectively address this problem. Multidimensional Scaling (MDS) and Principal Component Analysis ( ...

86. OOF3D: An Image-Based Finite Element Solver for Materials Science
Topic: Modeling
Published: 3/28/2012
Authors: Valerie R. Coffman, Andrew C.E. Reid, Stephen Langer, Gunay Dogan
Abstract: Recent advances in experimental techniques (micro CT scans, automated serial sectioning, electron back-scatter diffraction, synchrotron radiation x-rays) have made it possible to characterize the full, three dimensional structure of real materials. S ...

87. On Parameter Differentiation for Integral Representations of Associated Legendre Functions
Topic: Modeling
Published: 5/24/2011
Author: Howard S Cohl
Abstract: For integral representations of associated Legendre functions in terms of modified Bessel functions, we establish justification for differentiation under the integral sign with respect to parameters. With this justification, derivatives for associate ...

88. On a generalization of the generating function for Gegenbauer polynomials
Topic: Modeling
Published: 1/28/2013
Author: Howard S Cohl
Abstract: We derive a Gegenbauer polynomial expansion for complex powers of the distance between two points in $d$-dimensional Euclidean space. The argument of the Gegenbauer polynomial in the expansion is given by the cosine of the separation angle between th ...

89. On the Delay and Data Rate Performance of Throughput-Efficient Multi-Channel Access Algorithms in Cognitive Radio Networks
Topic: Modeling
Published: 7/8/2013
Authors: Kamran Sayrafian, Luca Zappaterra, Hyeong-Ah Choi, Jari Iinatti
Abstract: Cognitive Radio Networks (CRNs) are designed to increase spectrum utilization by allowing unlicensed secondary users (SUs) to operate over existing wireless channels where primary users (PUs) have license to transmit. An SU searches for channels not ...

90. Onset of Convection in Binary Liquid Layers
Topic: Modeling
Published: 3/24/2010
Authors: Geoffrey B McFadden, Sam Ray Coriell, Aaron Lott
Abstract: We perform linear stability calculations for horizontal bilayers of a two-component fluid that can undergo a phase transformation, taking into account both buoyancy effects and thermocapillary effects in the presence of a vertical temperature gradien ...
