A publicação da Revista Brasileira de Enfermagem – REBEn, além de descortinar aspectos importantes da história da enfermagem brasileira, permite acompanhar diversos movimentos que se entrecruzaram a essa história, como o movimento eugenista, cujas primeiras manifestações ocorreram no Brasil nas…

In this paper, the results of optical investigations for thin films of carbon-palladium (C-Pd) nanocomposites are presented. This films were prepared using two steps method (PVD/ CVD). The optical and Raman spectroscopy has been used to characterize the material. The…

The paper presents mathematical model - TOPSIS method, which was utilized on insulating state of distribution transformer to analyze and sensibility of individual measurements methods mutual comparison. We can uniquely determine the importance of these measurements methods with this mathematical…

The article presents a current-mode full-wave rectifier employing multiple output current follower transconductance amplifier (MO-CFTA). The both circuits description is very simple, it merely comprises only single MO-CFTA, without external passive element. In addition, the magnitude and direction of output…

Alternative for adjust optical fiber light-guiding properties by bulk glass doping is provided by microstructured optical fibers, which allows access directly to the light guiding core via their microstructure. Following paper will report utilizing of suspended-core, so-called high-delta, microstructured optical…

The harmonic impedance of the power system is an important quantity, which describes the behaviour of the power system with the existence of different frequencies beside the fundamental. The harmonic study belongs to the most difficult part of the electrical…

The paper deals with a new concept of power electronic two-phase system with two-stage DC/AC/AC converter and two-phase IM/PMSM motor. The proposed system consisting of two-stage converter comprises: input resonant boost converter with AC output, two-phase half-bridge cyclo-converter commutated by…

This paper describes the performance of LTE advanced uplink transmission in a flat Rayleigh channel. The uplink is simulated using a modified version of the Vienna uplink link level matlab code simulator. This modified version supports two transmission antennas instead…

Certain multimedia and voice services, such as VoIP, IPTV, etc., are significantly delay sensitive and their performance is influenced by the overall transmission delay and its variance. One of the most common solutions used in access networks are xDSL lines,…
