General polynomial factorization-based design of sparse periodic linear arrays [PDF]
, 2010 We have developed several methods of designing sparse periodic arrays based upon the polynomial factorization method. In these methods, transmit and receive aperture polynomials are selected such that their product results in a polynomial representing ...

Time-relevant 2D behaviors [PDF]
, 2011 In this work we present some results on 2D behaviors described by linear constant coefficient partial difference equations where one of the independent variables, “time”, is distinguished and plays a special role. We call such systems ‘time-relevant’. We

Factorization of polynomial x^n-1 over finite fields
四川大学学报. 自然科学版, 2019 Factorization of the polynomial x^n-1 over finite fields is not only important theoretically, but also has a lots of applications, especially in secure communication and error-correcting coding theory.

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

Negacyclic Codes of Length
IEEE Access, 2019 Let $F_{q}$ be a finite field of odd order $q$ . Let $m$ be a positive integer such that $X^{2^{m}}+1$ factors completely into degree-one factors in $F_{q^{2}}[X]$ . The polynomial generators of all negacyclic codes of length $2^{m}p^{n}$ over

Advanced Engineering Materials, EarlyView.We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Topology and factorization of polynomials
MATHEMATICA SCANDINAVICA, 2009 For any polynomial $P\in {\mathsf C} [X_1,X_2,\ldots,X_n]$, we describe a $\mathsf C$-vector space $F(P)$ of solutions of a linear system of equations coming from some algebraic partial differential equations such that the dimension of $F(P)$ is the number of irreducible factors of $P$.
