2017/3/14
The oft-quoted proverb, “Too many cooks spoil the broth,” is apt wisdom for describing challenges facing policy makers, public resource managers, ag producers, industry, residents and other ...
Segmentation of ARX-models using sum-of-norms regularization
Segmentation Regularization ARX-models
2015/8/7
Segmentation of time-varying systems and signals into models whose parameters are piecewise constant in time is an important and well studied problem. It is here formulated as a least-squares problem ...
Maximizing a sum of sigmoids
Sigmoid function convex constraint set mathematics marketing network planning
2015/8/7
The problem of maximizing a sum of sigmoidal functions over a convex constraint set arises in many application areas. This objective captures the idea of decreasing marginal returns to investment, and...

Metaplectic Eisenstein Series Gauss Sum Combinatorics
2015/7/6
For metaplectic covers of these groups, the Whittaker models may or may not be
unique. Gelbart and Piatetski-Shapiro considered the representations of the double
cover of SL2 that have unique Whitta...
Tractable fitting with convex polynomials via sum-of-squares
via sum-of-squares Tractable fitting
2015/6/19
We consider the problem of fitting given data with a convex polynomial. A technique to solve this problem using sum of squares polynomials is presented. This technique is extended to enforce convexity...

Time Delays via Polynomial Systems
2015/6/19
We present a methodology for analyzing robust independent-of-delay and delay-dependent stability of equilibria of systems described by nonlinear Delay Differential Equations by algorithmically constru...
CHIRAL SUM-RULES AND THEIR PHENOMENOLOGY

2014/12/23
We present an analysis of four sum rules, each based on chiral symmetry and containing the difference ρV(s) − ρA(s) of isovector vector and axialvector spectral functions. Experimental data from...
Calculation of a weak nonleptonic matrix element using “Weinberg” sum rules
Weak matrix element vector and axis vector spectrum function spectral function
2014/12/23
There is a ``toy'' weak matrix element which can be expressed as an integral over the vector and axial vector spectral functions, $\rho_V (s) - \rho_A (s)$. I review our recent evaluation of these spe...
