This paper aims to investigate the structural, optical and electrical properties of PEO doped with NiO. The DFT calculations have been performed using Gaussian 09 package of programs. The calculated electronic properties...

Motorbikes are an object that is very prone to being stolen, anticipating theft is not enough just by installing a safety lock, but it needs to be equipped with a monitoring and control system to reduce theft of motorbik...

The main objective of this research work is to develop a new low-cost isolated three-level ac-dc power converter topology with a reduced number of switches. Existing three-level converter topologies change ac power to dc...

Abstract The software-defined radio has been allowing engineers the possibility of implementing operations on software that were previously only possible to be performed through hardware. With the continuous increase in ...

Abstract This article presents the development of an inclinometer device based on a Mach-Zehnder interferometer considering the effects caused by temperature variations. It was demonstrated the operation of a LPG-taper s...

Raspberry Pi is a single board computer that the author uses as a voip server based on asterisk. To use this voip network, each device must have a static IP as well as be connected to a stable network. The advantage of u...

Abstract We proposed and analyzed a planar narrow-band absorber based on a bi-layer metal/dielectric structure. The planar absorber uses the Fabry-Pérot resonance and the inherent loss of the metals, for maximum light a...
