Abstract: This article presents a method for estimating a linear time-varying approximation of a general class of nonlinear time-varying (NLTV) systems. It starts from noisy measurements of the ...

Abstract: Model order reduction of input affine nonlinear systems via trajectory piecewise linear approximation is a well known practice. This method along with its variants is known to generate ...

Global ecosystems are under threat from the rapid expansion of linear infrastructure (LI)‚ – roads, railroads, power lines, fences, pipelines, and canals. LI development can obstruct wildlife movement ...

I started thinking about getting our house in order when Tavia’s father died. Tavia, my friend from early childhood (and youth, and middle age, and these years on the downhill slalom), grew up in unit ...

Pi Approximation Day occurs every July 22nd. It celebrates pi, a key mathematical constant. Pi relates a circle's circumference to its diameter. William Jones introduced the π symbol in 1706.

Nick Trefethen, professor of applied mathematics in residence at Harvard University, will present the 2025 Russell E. Marker Lectures in Mathematics, collectively titled “Numerical Rational Functions, ...

This paper presents two sets of considerations on the use of approximations to estimate freight trip generation (FTG) and freight generation (FG) rates, based on a single variable. Following recent ...

SiC-based converters and inverters are the optimal choice for battery-operated vehicles (BEVs), renewables, and all other applications where maximum efficiency is required. Silicon Carbide (SiC) ...

Can a simple daily practice truly restore our peace amidst the stress and chaos of modern life? One such practice is gratitude, a core principle of positive psychology that has garnered significant ...

Transportation Science, Vol. 38, No. 3 (August 2004), pp. 343-356 (14 pages) Bounds and approximate formulae are developed for the average optimum distance of the transportation linear programming ...
