In recent years, as performance and capacity of main and external memory grow, performance of database management systems (DBMSes) on certain kinds of queries is more determined by raw CPU speed. Currently, PostgreSQL uses the interpreter to execute

The paper considers the construction of adaptive methods based on the explicit Runge–Kutta stages. The coefficients of these methods are adjusted to the problem being solved, using component-wise estimates of the eigenvalues of the Jacobi matrix wi

Problems connected with the use of quantum-cascade lasers (QCLs) in biomedical practice are discussed. A comparative analysis was made of laser spectroscopic methods for noninvasive diagnostics of diseases by exhaled air; examples of the practical im

The main computational costs of implicit Runge–Kutta methods are caused by solving a system of algebraic equations at every step. By introducing explicit stages, it is possible to increase the stage (or pseudo-stage) order of the method, which make

We consider methods that are the inverse of the explicit Runge–Kutta methods. Such methods have some advantages, while their disadvantage is the low (first) stage order. This reduces the accuracy and the real order in solving stiff and differential

The solution of stiff problems is frequently accompanied by a phenomenon known as order reduction. The reduction in the actual order can be avoided by applying methods with a fairly high stage order, ideally coinciding with the classical order. Howev
