INTRODUCTION TO NUMERICAL RELATIVITY

Introduction to Numerical Relativity

Numerical Relativity is a multidisciplinary field including Wipes relativity, magneto-hydrodynamics, astrophysics and computational methods, among others, with the aim of solving numerically highly-dynamical, strong-gravity scenarios where no other approximations are available.Here we describe some of the foundations of the field, starting from the

Collembola laterally move biochar particles.

Biochar is being discussed as a soil amendment to improve soil fertility and mitigate climate change.While biochar interactions with soil microbial biota have been frequently studied, interactions with soil mesofauna are understudied.We here present an experiment in which we tested if the collembolan Folsomia candida I) can transport biochar partic

Global control of reaction wheel pendulum through energy regulation and extended linearization of the state variables

This paper presents the design and simulation of a global controller for the Reaction Wheel Pendulum system using energy regulation and extended linearization methods for the state feedback.The CASEIN proposed energy regulation is based on the gradual reduction of the energy of the system to reach the unstable equilibrium point.The signal input for
