A Path-Following Algorithm for Linear Programming Using Quadratic and Logarithmic Penalty Functions [PDF]

open access: yesSIAM Journal on Control and Optimization, 1993
Summary: Motivated by a recent work of \textit{R. Setiono} [`An interior dual proximal point algorithm for linear programs', Tech. report, Computer Sci. Dept., Univ. of Wisconsin, Madison, WI/USA (1989)], a path-following algorithm for linear programming using both logarithmic and quadratic penalty functions is proposed. In the algorithm, a logarithmic

Adaptive estimation for Hawkes processes; application to genome analysis [PDF]

open access: yes, 2010
The aim of this paper is to provide a new method for the detection of either favored or avoided distances between genomic events along DNA sequences. These events are modeled by a Hawkes process.

Semiparametric Multinomial Logit Models for Analysing Consumer Choice Behaviour [PDF]

open access: yes, 2006
The multinomial logit model (MNL) is one of the most frequently used statistical models in marketing applications. It allows to relate an unordered categorical response variable, for example representing the choice of a brand, to a vector of covariates ...

A Modified Higher-Order Singular Value Decomposition Framework With Adaptive Multilinear Tensor Rank Approximation for Three-Dimensional Magnetic Resonance Rician Noise Removal

open access: yesFrontiers in Oncology, 2020
The magnetic resonance (MR) images are acknowledged to be inevitably corrupted by Rician distributed noise, which adversely affected the image quality for diagnosis purpose.

Inexact Convex Relaxations for AC Optimal Power Flow: Towards AC Feasibility

open access: yes, 2020
Convex relaxations of AC optimal power flow (AC-OPF) problems have attracted significant interest as in several instances they provably yield the global optimum to the original non-convex problem.

Quasi-static imaged-based immersed boundary-finite element model of human left ventricle in diastole [PDF]

open access: yes, 2014
SUMMARY: Finite stress and strain analyses of the heart provide insight into the biomechanics of myocardial function and dysfunction. Herein, we describe progress toward dynamic patient-specific models of the left ventricle using an immersed boundary ...

On adaptive estimation of linear functionals [PDF]

open access: yes, 2005
Adaptive estimation of linear functionals over a collection of parameter spaces is considered. A between-class modulus of continuity, a geometric quantity, is shown to be instrumental in characterizing the degree of adaptability over two parameter spaces

Penalized nonparametric mean square estimation of the coefficients of diffusion processes [PDF]

open access: yes, 2007
We consider a one-dimensional diffusion process $(X_t)$ which is observed at $n+1$ discrete times with regular sampling interval $\Delta$. Assuming that $(X_t)$ is strictly stationary, we propose nonparametric estimators of the drift and diffusion ...

A Topology-Preserving Level Set Method for Shape Optimization

open access: yes, 2004
The classical level set method, which represents the boundary of the unknown geometry as the zero-level set of a function, has been shown to be very effective in solving shape optimization problems.

A distributed algorithm for demand-side management: Selling back to the grid

open access: yesHeliyon, 2017
Demand side energy consumption scheduling is a well-known issue in the smart grid research area. However, there is lack of a comprehensive method to manage the demand side and consumer behavior in order to obtain an optimum solution.
