An Insight into the Data Structure of the Dynamic Batch Means Algorithm with Binary Tree Code

Mathematics, 2019
Batching is a well-known method used to estimate the variance of the sample mean in steady-state simulation. Dynamic batching is a novel technique employed to implement traditional batch means estimators without the knowledge of the simulation run length

Recursive Method for Nekrasov partition function for classical Lie groups [PDF]

, 2014
Nekrasov partition function for the supersymmetric gauge theories with general Lie groups is not so far known in a closed form while there is a definition in terms of the integral.

Special-case closed form of the Baker–Campbell–Hausdorff formula [PDF]

Journal of Physics A: Mathematical and Theoretical, 2015
The Baker-Campbell-Hausdorff formula is a general result for the quantity $Z(X,Y)=\ln( e^X e^Y )$, where $X$ and $Y$ are not necessarily commuting. For completely general commutation relations between $X$ and $Y$, (the free Lie algebra), the general result is somewhat unwieldy.

CLOSED FORM PRICING FORMULAS FOR DISCRETELY SAMPLED GENERALIZED VARIANCE SWAPS

Mathematical Finance, 2011
Most of the existing pricing models of variance derivative products assume continuous sampling of the realized variance processes, though actual contractual specifications compute the realized variance based on sampling at discrete times. We present a general analytic approach for pricing discretely sampled generalized variance swaps under the ...

Approximate Closed-Form Formulas for the Zeros of the Bessel Polynomials [PDF]

International Journal of Mathematics and Mathematical Sciences, 2012
We find approximate expressionsx̃(k,n,a)andỹ(k,n,a)for the real and imaginary parts of thekth zerozk=xk+iykof the Bessel polynomialyn(x;a). To obtain these closed-form formulas we use the fact that the points of well-defined curves in the complex plane are limit points of the zeros of the normalized Bessel polynomials.

Iterative and Non-Iterative Theoretical Closed Forms Discrete Cosine Transform-Based Incremental LMS

IEEE Access
Novel closed-form expressions of the discrete cosine transform (DCT)-based iterative and non-iterative incremental least mean square (DCTILMS) algorithms are derived here for wireless sensor networks (WSNs) and agent localization. As a direct application
