Department of Mechanical Engineering, The University of Louisiana at Lafayette, Lafayette, LA, USA. The study of curvature in geometry and its relationship with differential equations is a central ...

"We show that this design can, in principle, find half of all existing Earth-like planets orbiting sun-like stars within 30 light-years in less than three years." When you purchase through links on ...

A new method is presented for solving Poisson's equation inside a rectangular waveguide. The method uses Fast Fourier Transforms (FFTs) to perform mixed convolutions and correlations of the charge ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Urban soil science is critical and expanding. Urbanization rates continue to rise, leading to more urban lands and higher human population densities in urban areas. This leads to increased soil ...

A description of a four-phase RC oscillator of a sinusoidal and rectangular shape is given. A triangular-shaped signal is obtained by the counterphase addition of half-waves of sinusoidal signals ...

Despite the overall ease of controlling a car, the statistics still show many drivers get into accidents. Although it’s not always the fault of the person behind the wheel, people can often trip over ...

Abstract: In this article, we present the dyadic Green’s functions (DGFs) for electric dipole excitation of perfect electromagnetic conductor (PEMC) rectangular waveguides and cavities. To derive the ...
