A unifying framework for finite wordlength realizations [PDF]
, 2007 A general framework for the analysis of the finite wordlength (FWL) effects of linear time-invariant digital filter implementations is proposed. By means of a special implicit system description, all realization forms can be described.

A Practical pedestrian approach to parsimonious regression with inaccurate inputs [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2014 A measurement result often dictates an interval containing the correct value. Interval data is also created by roundoff, truncation, and binning. We focus on such common interval uncertainty in data.

Quantifying Numerical Energy Dissipation in Implicit Large Eddy Simulations
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.Abstract A novel methodology, using energy tracers, is introduced with the aim of diagnosing numerical energy dissipation, both globally and locally, in numerical models of the atmosphere. Energy dissipation might correspond to some physical process, such as the cascade of kinetic energy to unresolved scales if that energy is not restored as heat ...

The Role of Dice in the Emergence of the Probability Calculus
International Statistical Review, Volume 94, Issue 2, Page 464-483, August 2026.Summary The early development of the probability calculus was clearly influenced by the roll of dice. However, while dice have been cast since time immemorial, documented calculations on the frequency of various dice throws date back only to the mid‐13th century.

Network-coded internet-friendly transport protocol
Journal of Algorithms & Computational Technology, 2017 This paper presents the design of network-coded TCP (NCTCP). NCTCP is a reliable TCP-like transport protocol that uses network coding to dramatically improve the overall performance in networks with lossy links.

FloeNet: A Mass‐Conserving Global Sea Ice Emulator That Generalizes Across Climates
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract We introduce FloeNet, a graph neural network trained to emulate the Geophysical Fluid Dynamics Laboratory global sea ice model, SIS2. FloeNet is a mass‐conserving model, emulating 6‐hr mass and area budget tendencies related to sea ice and snow‐on‐sea‐ice growth, melt, and advection.

Convergence and roundoff errors in a two-dimensional eigenvalue problem using spectral methods and Arnoldi-Chebyshev algorithm [PDF]
, 2007 We show that an efficient way for solving 2D stability problems in fluid mechanics is to use, after discretization of the equations that cast the problem in the form of a generalized eigenvalue problem, the incomplete Arnoldi-Chebyshev method.

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver
International Journal for Numerical Methods in Fluids, Volume 98, Issue 7, Page 804-839, July 2026.A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for

Optimal realizations of floating-point implemented digital controllers with finite word length considerations. [PDF]
, 2004 The closed-loop stability issue of finite word length (FWL) realizations is investigated for digital controllers implemented in floating-point arithmetic. Unlike the existing methods which only address the effect of the mantissa bits in floating-point
