A bisection method for computing the H_infinity-norm of a transfer matrix and related problems
Transfer matrix singular value assessment the Hamiltonian matrix characteristic values of linear algebra
2015/8/13
Inspired by recent work of Byers we establish a simple connection between the singular values of a transfer matrix evaluated along the imaginary axis and the imaginary eigenvalues of a related Hamilto...
Method of centers for minimizing generalized eigenvalues

Bilinear matrix inequality linear matrix in-equality semide
2015/8/11
In this paper we present a path-following (homotopy) method for (locally) solving bilinear matrix inequality (BMI) problems in control. The method is to linearize the BMI using a first order perturbat...
Rainfall-Runoff Modeling for an Experimental Watershed of Western Greece Using Extended Time-Area Method and GIS
Rainfall-runoff modeling Forested watershed Time-area method Flow velocity
2015/8/11
In this study, an effort was made to simulate the transformation of rainfall into runoff, in a small experimental mountainous-forested watershed in western Greece. The main objective was the productio...
Erosion Risk Assessment using an Empirical Model of Pacific South West Inter Agency Committee Method for Zargeh Watershed, Iran
MPSIAC Erosion Sediment Yield Iran
2015/8/11
Watershed degradation due to soil erosion and sedimentation is one of the major environmental problems in Iran. In addressing the issue, a study on the validity of an empirical model of Pacific South ...
PLUME-MoM 1.0: A new integral model of volcanic plumes based on the method of moments
PLUME-MoM moments
2015/8/11
In this paper a new integral mathematical model
for volcanic plumes, named PLUME-MoM, is presented.
The model describes the steady-state dynamics of a plume
in a 3-D coordinate system, accounting f...
A heuristic method for statistical digital circuit sizing

2015/8/10
In this paper we give a brief overview of a heuristic method for approximately solving a statistical digital circuit sizing problem, by reducing it to a related deterministic sizing problem that inclu...
An efficient method for large-scale slack allocation
timing graph slack allocation delay budgeting convex optimization truncated Newton method
2015/8/7
We consider a timing or project graph, with given delays on the edges and given arrival times at the source and sink nodes. We are to find the arrival times at the other nodes; these determine the tim...
