Envelope Theorems for Arbitrary Choice Sets

by Paul Milgrom, Ilya Segal - ECONOMETRICA , 2002
"... The standard envelope theorems apply to choice sets with convex and topological structure, providing sufficient conditions for the value function to be differentiable in a parameter and characterizing its derivative. This paper studies optimization with arbitrary choice sets and shows that the tradi ..."

A spectral algorithm for envelope reduction of sparse matrices

by Stephen T. Barnard, Alex Pothen, Horst D. Simon - ACM/IEEE CONFERENCE ON SUPERCOMPUTING , 1993
"... The problem of reordering a sparse symmetric matrix to reduce its envelope size is considered. A new spectral algorithm for computing an envelope-reducing reordering is obtained by associating a Laplacian matrix with the given matrix and then sorting the components of a specified eigenvector of the ..."

show that the new reordering algorithm usually computes smaller envelope sizes than those obtained from the current standards such as the Gibbs-Poole-Stockmeyer (GPS) algorithm or the reverse Cuthill-McKee (RCM) algorithm in SPARSPAK, in some cases reducing the envelope by more than a factor of two.

Standard Lyndon bases of Lie algebras and enveloping algebras

Transcriptional adaptation of Mycobacterium tuberculosis within macrophages: insights into the phagosomal environment

by Sabine Ehrt, Martin I. Voskuil, Yang Liu, Joseph A. Mangan, Irene M. Monahan, Gregory Dolganov, Brad Efron, Philip D. Butcher, Carl Nathan, Gary K. Schoolnik - J Exp Med , 2003
"... Little is known about the biochemical environment in phagosomes harboring an infectious agent. To assess the state of this organelle we captured the transcriptional responses of Mycobacterium tuberculosis (MTB) in macrophages from wild-type and nitric oxide (NO) synthase 2–deficient mice before and ..."

The intraphagosomal transcriptome was compared with the transcriptome of MTB in standard broth culture and during growth in diverse conditions designed to simulate features of the phagosomal environment. Genes expressed differentially as a consequence of intraphagosomal

APPLICATION OF IT AND INTERNATIONAL STANDARDS TO EVALUATE BUILDING ENVELOPE PERFORMANCE

by Hua Sheng He, Amin Hammad, Paul Fazio
"... Improving thermal performance of building envelopes reduces energy consumption of residential buildings. This reduction is better fostered if the thermal analysis is included in the overall performance analysis of the building envelope or the building system. An integrated approach with IT and inter ..."

with IT and international standards, such as IFC, can ensure that the building envelope satisfies energy requirements as well as other requirements such as hygrothermal, acoustic, aesthetic, or economic criteria. This paper presents the concept of a building envelope performance evaluation framework which includes an IFC

Efficient Spectral Envelope Estimation and its application to pitch shifting and envelope preservation

by A. Röbel - Proceedings of the 8th International Conference on Digital Audio Effects , 2005
"... In this article the estimation of the spectral envelope of sound signals is addressed. The intended application for the developed algorithm is pitch shifting with preservation of the spectral envelope in the phase vocoder. As a first step the different existing envelope estimation algorithms are inv ..."

increased computational complexity compared to the standard LPC algorithm but offers significantly improved control over the envelope characteristics. The application of the true envelope estimator in a pitch shifting application is investigated. The main problems for pitch shifting with envelope

Energy Minimization for Linear Envelope MRFs

by Pushmeet Kohli, M. Pawan Kumar
"... Markov random fields with higher order potentials have emerged as a powerful model for several problems in computer vision. In order to facilitate their use, we propose a new representation for higher order potentials as upper and lower envelopes of linear functions. Our representation concisely mod ..."
Abstract - Cited by 26 (8 self) - Add to MetaCart
models several commonly used higher order potentials, thereby providing a unified framework for minimizing the corresponding Gibbs energy functions. We exploit this framework by converting lower envelope potentials to standard pairwise functions with the addition of a small number of auxiliary variables

Submodule Envelope Measurement Report

by V. Guarino, N. Hill, E. Petereit, J. Proudfoot, K. Wood
"... We report submodule envelope measurements made on the submodules used for the assembly of AE0. The standard height measurements,show an interesting systematic effect which is not understood, but does not have a significant affect on the mechanical assembly of the prototype. A set of precision measur ..."

Adaptive envelope-constrained filtering

by Ba-ngu Vo, Sumeetpal Singh, Vladislav Tadic - 2003 IEEE international conference on acoustics, speech, and signal processing, Hong Kong , 2003
"... In the discrete-time Envelope-Constrained filtering problem, the gain of the filter is minimised subject to the constraint that the filter output to a prescribed input fits into a given envelope. In this paper, a novel adaptive algorithm for solving this problem based on stochastic optimisation is p ..."
