Engineering Mathematics: Even though engineering is more varied than ever in 2026, some mathematical principles are still applicable. Calculus (including Differential Equations) and Linear Algebra are ...

THE Ministry of Education has issued detailed guidance to Grade 10 and Grade 11 students as they prepare for the second Caribbean Secondary Education Certificate (CSEC) mathematics mock examinations ...

Abstract: Positron emission tomography (PET) is an important imaging technique to visualize a number of functions in the brain or human body. For reconstructing PET images from the sinogram data, an ...

Dozens of machine learning algorithms require computing the inverse of a matrix. Computing a matrix inverse is conceptually easy, but implementation is one of the most difficult tasks in numerical ...

Rice grain is considered a complex matrix. Thus, the extraction and clean-up steps must be carefully studied. The most frequent strategies are based on liquid-liquid; solid-phase; as well as ...

A UNSW Sydney mathematician has discovered a new method to tackle algebra's oldest challenge—solving higher polynomial equations. Polynomials are equations involving a variable raised to powers, such ...

Abstract: An H-matrix accelerated direct solver employing the high-order Chebyshev-based Boundary Integral Equation (CBIE) method has been formulated, tested, and profiled for performance on high ...

Computer scientists are a demanding bunch. For them, it’s not enough to get the right answer to a problem — the goal, almost always, is to get the answer as efficiently as possible. Take the act of ...

Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei, which give them different atomic masses. Percent abundance is the percentage of an isotope’s occurrence ...

Article subjects are automatically applied from the ACS Subject Taxonomy and describe the scientific concepts and themes of the article. We present a combination of the contact-less sample handling, ...

Schematic separation of configuration space in the R-matrix method. The outer region Schrödinger equation is a set of multichannel coupled differential equations and the R-matrix is the inverse ...
