In his decades-long career in tech journalism, Dennis has written about nearly every type of hardware and software. He was a founding editor of Ziff Davis’ Computer Select in the 1990s, senior ...

Trying to kill algae with chemicals is a common response when community ponds or other water features go green, but a ...

Abstract: Inhomogeneous linear ordinary differential equations (ODEs) and systems of ODEs can be solved in a variety of ways. However, hardware circuits that can perform the efficient analog ...

There is growing evidence that the current globalised agri-food system is neither sustainable nor resilient. It is responsible for around one third of the global GHG emissions and is a major driver of ...

Abstract: In this article, we provide a system-theoretic treatment of certain continuous-time homogeneous polynomial dynamical systems (HPDS) via tensor algebra. In particular, if a system of ...

Striving to increase workplace diversity is not an empty slogan — it is a good business decision. A 2015 McKinsey report on 366 public companies found that those in the top quartile for ethnic and ...

Differential method and homotopy analysis method are used for solving the two-dimensional reaction-diffusion model. And the structure of the solutions is analyzed. Finally, the homotopy series ...
