Polarization of Light Scattered by Particles on Silicon Wafers

January 1, 1999
Author(s)
Li Piin Sung, George W. Mulholland, Thomas Germer
Bidirectional ellipsometry has been developed as a technique for distinguishing among various scattering features near surfaces.Employi Employing incident light with fixed polarization, the technique measures the principal angle of polarization and the

An efficient curve evolution algorithm for multiphase image segmentation

January 7, 2015
Author(s)
Gunay Dogan
We propose a novel iterative algorithm for segmentation of multiphase images by curve evolution. Specifically, we address a multiphase version of the Chan-Vese piecewise constant segmentation energy. Our algorithm is efficient: it is based on an explicit

On The Reversion of an Asymptotic Expansion and the Zeros of the Airy Functions

January 15, 1999
Author(s)
Bruce R. Fabijonas, Frank W. Olver
The general theories of the derivation of inverses of functions from their power series and asymptotic expansions are discussed and compared. The asymptotic theory is applied to obtain asymptotic expansions of the zeros of the Airy functions and their

Modeling Spatial Reasoning Systems With Shape Algebras and Formal Logic

June 1, 1996
Author(s)
Scott Chase
The combination of the paradigms of shape algebras and predicate logic representations,used in a new method for describing designs, is presented. First order predicate logicprovides a natural, intuitive way of representing shapes and spatial relations

Energy Balance in a Large Compartment Fire. (POSTER ABSTRACTS)

September 18, 2005
Author(s)
Anthony P. Hamins, Erik L. Johnsson, Michelle K. Donnelly
The experiments described here were part of an international collaborative project to assess and validate fire computer codes for nuclear power plant applications. Understanding the distribution of energy released by a fire is important for testing the

Experimental observation of thermalisation with noncommuting charges

February 9, 2022
Author(s)
Florian Kranzl, Aleksander Lasek, Manoj Joshi, Amir Kalev, Rainer Blatt, Christian Roos, Nicole Halpern
… Quantum simulators have recently enabled experimental observations of quantum many-body systems' internal thermalisation. Often, … particle number—in a microcanonical subspace. How- ever, quantum evolution can also conserve quantities, or charges, …

Recommendation for the Triple Data Encryption Algorithm (TDEA) Block Cipher

January 23, 2012
Author(s)
William C. Barker, Elaine B. Barker
This publication specifies the Triple Data Encryption Algorithm (TDEA), including its primary component cryptographic engine, the Data Encryption Algorithm (DEA). When implemented in an SP 800-38-series-compliant mode of operation and in a FIPS 140-2
