We consider the electromagnetic field of a charge moving with a constant acceleration along an axis. We find that this field obtained from the Li´enard–Wiechert potentials does not satisfy Maxwell equations if one considers ...

Recommender Systems (RSs) are powerful and popular tools for e-commerce. To build their recommendations, RSs make use of varied data sources, which capture the characteristics of items, users, and their transactions. Despite ...

This paper details the design and implementation of a simultaneous dual true random numbers generator using only one laser and a digital signal processing system with a DE0 Nano FPGA. We implemented the random generator ...

Copper nanoparticles (NCu) may co-exist with other pollutants in agricultural soils, such as pesticides. However, this has been little evaluated yet. Thus, possible effects of the simultaneous applications of pesticides ...

This document examines the two-way relationship between health and employment and their dynamics using U.S. data from the PSID (Panel study of Income Dynamics). This study uses two dependent variables (Self-assessed health ...

En el presente trabajo se realiza una aproximación a la relación endógena entre el desarrollo económico de los municipios en Colombia y su tasa de emprendimiento. Por lo tanto, se explora un modelo de dos ecuaciones ...

resumen: Los procesos y su sistema de control se diseñan de forma independiente y secuencial. Dicho procedimiento no garantiza que el sistema de control funcione correctamente, y en ocasiones es necesario realizar ...
