A Fast Amplitude Approximation For Quadrature Pairs
Bell System Technical Journal, 1971This paper gives an algorithm from which an approximation to the amplitude of a quadrature pair can be obtained simply and without requiring more bits than are needed to represent the largest allowable amplitude, A. If A cos θ and A sin θ are a quadrature pair, the amplitude is $A=(A^{2}\cos^{2}\theta + A^{2}\sin^{2}\theta)^{1\over 2}.$ If AX is the ...

On realizations of an approximation random quadrature formula
USSR Computational Mathematics and Mathematical Physics, 1983The coefficients \(c=\int f(x)\Phi(x)\mu(dx)\) of the least square approximation of f according to a system \(\Phi =(\phi_ 1,...,\phi_ m)\) of \(\mu\)-orthonormalized functions \(\{\phi_ k\}^ m_ 1\) satisfy a linear system of equations. The authors propose to approximate the integrals c by the solution \(\hat c\) of an approximation of this system ...

Approximate Value Iteration Based on Numerical Quadrature
IEEE Robotics and Automation Letters, 2018Learning control policies has become an appealing alternative to the derivation of control laws based on classic control theory. Value iteration approaches have proven an outstanding flexibility, while maintaining high data efficiency when combined with probabilistic models to eliminate model bias.

TPQA: Three point quadrature approximation MPPT algorithm
2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS), 2013Growing concerns about environmental issues and the world energy crisis have attracted a great deal of interests for the development and application of the photovoltaic (PV) power system that uses the nonpolluting and the most abundant solar energy. This paper introduces a novel maximum power point tracking (MPPT) algorithm that is based on the fact ...

Bayesian quadrature with non-normal approximating functions
Statistics and Computing, 1998We consider an efficient Bayesian approach to estimating integration-based posterior summaries from a separate Bayesian application. In Bayesian quadrature we model an intractable posterior density function f(·) as a Gaussian process, using an approximating function g(·), and find a posterior distribution for the integral of f(·), conditional on a few ...
