Generalized Rational B‐Spline Bases via Homographic Parametrization and Applications

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
A new class of rational parametrization has been developed and was used to generate a new family of rational B‐splines, αGiki=0k, which depend on a parameter α ∈ (−∞, 0) ∪ (1, +∞). This family of functions satisfies, among other properties, positivity and the partition of unity.

Constructing a Set of Kronecker–Pauli Matrices

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
In quantum physics, the choice of basis is crucial for formulation. The generalization of the Pauli matrices via the Kronecker product, known as Pauli strings, is typically restricted to 2n‐dimensional systems. This paper explores extending this generalization to n‐dimensional systems, where n is an integer, n > 2, to construct n × n‐Kronecker–Pauli ...

Progressive development of cracks in biochar–cement composites through multiscale analysis

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 30, Page 5952-5971, 19 December 2025.
Abstract The intrinsic brittleness of the cement matrix limits its synergy with steel reinforcement bars, constraining energy dissipation and crack control capacity of concrete. Enhancing the ductility of cementitious materials is, therefore, essential for improving structural resilience.

Computationally Enhanced Paper‐Like Problem Solving: pSolver as a Digital Notebook for Engineering Education

Computer Applications in Engineering Education, Volume 33, Issue 6, November 2025.
ABSTRACT Engineering problem solving is a fundamental component of technology education. However, students often struggle due to mathematical complexity, fragmented computing tools, and limited instructional time. Although technical computing software is widely available, many tools lack transparency and tracking, which takes students away from the ...
