This Open Access book explores questions such as why and how did the first biological cells appear? And then complex organisms, brains, societies and –now– connected human societies? Physicists have good models for describing ...

Volume visualization is a difficult three-dimensional task and a significant amount of research is devoted to the development of a suitable computer input device for it. Most of the proposed models use fixed displays, thus ...

In this paper is proposed and analyzed a digital hysteresis modulation using a FPGA (Field Programmable Gate Array) device and VHDL (Hardware Description Language), applied at a hybrid three-phase rectifier with almost ...

The proposal of this work is to present the development and assembly of a virtual oscilloscope, by developing a software within the LabVIEW®, from National Instruments, together with Smart-Tech’s DAQ the PenDAq®, and scaling ...

Working from home has been a trend in recent years and has gained a monumental scale due to the coronavirus pandemic that started in 2020, when about 11 percent of Brazilians workers worked in this modality. Along with ...

This work presents a new high power factor three-phase rectifier based on a Y-connected differential autotransformer with reduced kVA and 18-pulse input current followed by three DC-DC boost converters. The topology provides ...
