چکیده
We derive Sobolev-type inner products with respect to which hat functions on arbitrary triangulations of domains in R are orthogonal. Compared with linear interpolation, the resulting approximation schemes yield superior accuracy at little extra cost.

Close interval approximation of piecewise quadratic fuzzy numbers for fuzzy fractional program
The fuzzy approach has undergone a profound structural transformation in the past few decades. Numerous studies have been undertaken to explain fuzzy approach for linear and nonlinear programs. While, the findings in earlier studies have been conflicting, recent studies of competitive situations indicate that fractional programming problem has a positive impact on comparative scenario. We pro...
متن کاملHybrid model predictive control of a nonlinear three-tank system based on the proposed compact form of piecewise affine model
In this paper, a predictive control based on the proposed hybrid model is designed to control the fluid height in a three-tank system with nonlinear dynamics whose operating mode depends on the instantaneous amount of system states. The use of nonlinear hybrid model in predictive control leads to a problem of mixed integer nonlinear programming (MINLP) which is very complex and time consuming t...
متن کاملApproximate explicit constrained linear model predictive control via orthogonal search tree
Solutions to constrained linear model predictive control problems can be pre-computed off-line in an explicit form as a piecewise linear state feedback on a polyhedral partition of the state space, avoiding real-time optimization. We suggest an algorithm that will determine an approximate explicit piecewise linear state feedback by imposing an orthogonal search tree structure on the partition. ...
متن کاملDiscrete Wavelet Transform of Approximation Order 2 with Improved Time-localization — the Slantlet Transform
The discrete wavelet transform is usually carried out by filter bank iteration, however, for a fixed approximation order this does not yield a discrete-time basis that is optimal with respect to timelocalization. This paper describes a new orthogonal discrete wavelet transform with approximation order two and improved timelocalization. It is not based on filter bank iteration, instead new filte...
متن کاملNumerical Solution of Fractional Order Differential-algebraic Equations Using Generalized Triangular Function Operational Matrices
This article introduces a new application of piecewise linear orthogonal triangular functions to solve fractional order differential-algebraic equations. The generalized triangular function operational matrices for approximating Riemann-Liouville fractional order integral in the triangular function (TF) domain are derived. Error analysis is carried out to estimate the upper bound of absolute er...
