Construction of coset codes in order to realize interference alignment
(2017-01-01)
Interference is usually viewed as an obstacle to communication in wireless networks. Therefore, we develop a new methodology to quantize the channel coefficients in order to realize interference alignment onto a 2-dimensional ...
Evaluation of acid stage and of hydrogen peroxide on alkaline extraction of eucalyptus kraft pulp
(2017-01-01)
The Elemental Chlorine Free (ECF) bleaching technology is very well established for kraft pulp bleaching due to its efficiency in bleaching processes, once it presents high brightness, besides low reversion. In this work ...
Parkinson disease identification using residual networks and optimum-path forest
(2018-08-20)
Known as one of the most significant neurodegenerative diseases of the central nervous system, Parkinson's disease (PD) has a combination of several symptoms, such as tremor, postural instability, loss of movements, ...
Enhancing brain storm optimization through optimum-path forest
(2018-08-20)
Among the many interesting meta-heuristic optimization algorithms, one can find those inspired by both the swarm and social behavior of human beings. The Brain Storm Optimization (BSO) is motivated by the brainstorming ...
Temperature and Electric Field Influence on the Electrical Properties of Light-Emitting Devices Comprising PEDOT:PSS/GPTMS/Zn2SIO4:Mn Composites
(2018-01-01)
In the present study, we analyze the influence of temperature and active layer thickness on the electrical properties of electroluminescent devices comprising a polymeric conductive blend (poly(3,4 ethylenedioxythiophene ...
Photovoltaic DG with accumulation, active and reactive power control for grid-connected and intentional islanding operations
(2018-01-12)
Considering the new challenges in the energetic scenario around the world, this paper proposes the implementation of a micro-grid with photovoltaic generation and local accumulation, considering its capability to operate ...

(2018-01-12)
This paper presents the development of an educational digital module able to generate control signals considering several modulation strategies for DC-to-AC converters, single and three-phase, to achieve the integration ...
Comparison between Lebaron-Perez and Dal Pai-Escobedo correction methods for diffuse irradiance measured by the meo shadowring method
(2017-01-01)
This study aims to determine the effectiveness of two methods of correction of diffuse irradiance measured with shadowbands: LeBaron-Perez method and Dal Pai-Escobedo method. For the LeBaron-Perez method, we use the original ...
Interactive android application for education in AC-to-DC converters
(2018-01-12)
The paper presents an Android application with a friendly and interactive approach to aid the teaching of AC-to-DC converters operating in steady-state. Some features of the proposed application are demonstrated through ...
Aspects of user profiles that can improve mobile augmented reality usage
(2017-11-16)
Augmented Reality (AR) applications running on mobile devices have become more popular in recent years. As with digital games, many developers have begun to direct their applications to mobile platforms, although the ...
