Experimental Study of the Stability of a Low-Cost C-Band Active Reflector Using Sentinel-1 Imagery
IEEE AccessThe application of Synthetic Aperture Radar (SAR) interferometry (InSAR) techniques when in the imaged areas the coherence is low and persistent scatterers are missing often demands the installation of artificial reflectors, usually represented by ...

On the maximum order of nilpotent transitive permutation groups
, 2014 Given two positive integers n and c, we determine an upper bound, as a function of n and c, for the maximum order of a finite nilpotent transitive group of degree n and nilpotency class at most c.Comment: 14 ...

High Relative Accuracy Computations With Covariance Matrices of Order Statistics
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In many statistical applications, numerical computations with covariance matrices need to be performed. The error made when performing such numerical computations increases with the condition number of the covariance matrix, which is related to the number of variables and the strength of the correlation between the variables. In a recent work,

A Scalable Real-Time Multi-Camera Vehicle Tracking System for Urban Environments
IEEE AccessReal-time Multi-Camera Vehicle Tracking (MCVT) systems are challenging to design and deploy due to the need for real-time processing at the edge, as well as issues such as high noise, low image resolution, and reidentification.

$L^p$-generic cocycles have one-point Lyapunov spectrum
, 2002 We show the sum of the first $k$ Lyapunov exponents of linear cocycles is an upper semicontinuous function in the $L^p$ topologies, for any $1 \le p \le \infty$ and $k$.
