Direct injection technology has changed how engines make power and use fuel. It allows precise control of the air-fuel mixture, improving both performance and efficiency. However, this design has one ...

This repository contains a MiniZinc model and a set of generated instances for the CP2025 paper The Work Task Variation Problem, Mikael Z. Lagerkvist and Magnus Rattfeldt.

Much of mathematics involves so-called forward problems. These problems begin with a model of a physical system — say, a ball rolling down an incline plane — and researchers use parameters, such as ...

With direct injection, engines can run with higher compression ratios, higher boost, and higher efficiencies. The marvel has lead to widespread downsizing of engines, ditching large naturally ...

An approach of solving the most fundamental and important geodetic tasks with usage of ellipsoidal chords (slant distances) proposed by Molodensky.

The initial-boundary and the inverse coefficient problems for the semilinear hyperbolic equation with strong damping are considered in this study. The conditions for the existence and uniqueness of ...

ABSTRACT: In the author’s recent publications, a parametric system biorthogonal to the corresponding segment of the exponential Fourier system was unusually effective. On its basis, it was discovered ...

Zhang Yimou, director of many of China’s most spectacular and successful movies, is to try his hand at sci-fi. He will direct a film adaptation of “The Three-Body Problem.” The project was announced ...
