Kaczmarz-Type Methods for Solving Matrix Equation AXB = C
This paper proposes a class of randomized Kaczmarz and Gauss–Seidel-type methods for solving the matrix equation AXB=C, where the matrices A and B may be either full-rank or rank deficient and the system may be consistent or inconsistent. These iterative

Hypoplasticity for Sand With Explicitly Defined Asymptotic States
ABSTRACT A hypoplastic model for sand with defined asymptotic states is proposed. The fourth‐order tensor A$\mathsf {A}$ is defined by modifying the compression relation of the reference hypoplastic model by von Wolffersdorff (HP). This enables the mathematical formulation of a hypoplastic model for sand including the asymptotic state boundary surface (

On some properties of k-circulant matrices with the generalized Pell-Padovan numbers
In this paper, we investigate the properties of the $k$-circulant matrix generated by the generalized Pell--Padovan numbers. We derive explicit formulas for the sum of entries, the maximum column sum norm ($\Vert \cdot \Vert _{1}$), the maximum row sum ...

On the domain of implicit functions in a projective limit setting without additional norm estimates
We examine how implicit functions on ILB-Fréchet spaces can be obtained without metric or norm estimates which are classically assumed. We obtain implicit functions defined on a domain D which is not necessarily open, but which contains the unit open ...

Numerical simulation of polyethylene rotational molding using the Smoothed Particle Hydrodynamics (SPH) method. ABSTRACT This work presents the development of a numerical model based on the smoothed particle hydrodynamics (SPH) method to simulate the rotational molding process of powder thermoplastic polymers, used in the manufacture of liners for high‐

Norms and Spread of the Fibonacci and Lucas RSFMLR Circulant Matrices
Circulant type matrices have played an important role in networks engineering. In this paper, firstly, some bounds for the norms and spread of Fibonacci row skew first-minus-last right (RSFMLR) circulant matrices and Lucas row skew first-minus-last right

STABILITY, COHOMOLOGY VANISHING, AND NONAPPROXIMABLE GROUPS
Several well-known open questions (such as: are all groups sofic/hyperlinear?) have a common form: can all groups be approximated by asymptotic homomorphisms into the symmetric groups $\text{Sym}(n)$ (in the sofic case) or the finite-dimensional unitary ...

Unbiased fully nonlinear data assimilation. Part 1: The stochastic particle flow filter
While the existing deterministic particle flow filter (PFF) has been applied successfully to nonlinear high‐dimensional systems, it tends to underestimate ensemble spread when using a small number of particles. We introduce the stochastic particle flow filter (SPFF), which incorporates an additional Gaussian noise term into the particle flow dynamics ...

ABSTRACT The increasing integration of distributed energy resources demands enhanced coordination between transmission system operators (TSOs) and distribution system operators (DSOs) to maintain reliable grid operation. Traditional approaches rely on hierarchical or distributed optimization schemes for power flow management, but these methods either ...
