Conditional Equations Related to Drygas Functional Equations
Annales Mathematicae SilesianaeWe determine the solutions of the conditional Drygas equation for functions f1 and f2 that satisfy (y2 + y)f1(x) = (x2 + x)f2(y) for all (x, y) ∈ ℝ2 under the additional conditions y = x2, or y = log(x), x > 0 or y = exp(x).

Joint Estimation Using Quadratic Estimating Function
Journal of Probability and Statistics, 2011 A class of martingale estimating functions is convenient and plays an important role for inference for nonlinear time series models. However, when the information about the first four conditional moments of the observed process becomes available, the ...

Quadratic functions with prescribed spectra [PDF]
Designs, Codes and Cryptography, 2012 We study quadratic Boolean functions f from F2n to F2, which are well-known to have plateaued Fourier spectrum Fs;f , i.e., their Fourier coefficients are in the set {0,+_2(n+s)/2 } for some integer 0 ≤ s ≤ n-1. For various types of integers n, we determine possible values of s, construct f with Fs;f for a prescribed s, and present enumeration results ...

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Invariants at fixed and arbitrary energy. A unified geometric approach
, 1995 Invariants at arbitrary and fixed energy (strongly and weakly conserved quantities) for 2-dimensional Hamiltonian systems are treated in a unified way. This is achieved by utilizing the Jacobi metric geometrization of the dynamics.

Advanced Engineering Materials, EarlyView.A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...
