1. Efficient Low-Complexity Optimized Channel Estimating Methods for OFDM-Based Low-Voltage Broadband Power Line Communication Systems
Abstract Broadband Power Line Communication (BB-PLC) technology enables data transmission for smart grid applications. Nevertheless, channel equalizers are required in the receiver to estimate and compensate for the nonlinear time-variant impulse response and noise interference effects introduced by the BB-PLC channel. In this paper, we append the Particle S

2. ELABORAÇÃO E USO DE ANIMAÇÕES COMO ESTRATÉGIA PARA O ENSINO DE MECANISMOS DAS REAÇÕES ORGÂNICAS
The Chemistry of organic compounds is present in many aspects of life on the planet. In addition to many substances in our body being organic compounds, the energy matrix is based on burning fossil fuels, the biodiesel industry is also linked to organic reactions as well as the pharmaceutical industry. However, Organic Reaction Mechanisms is considered one o

3. Two-dimensional beams in rectangular coordinates using the radial point interpolation method
Abstract The three-dimensional Theory of Elasticity equations lead to a complex solution for most problems in engineering. Therefore, the solutions are typically developed for reduced systems, usually symmetrical or two-dimensional. In this context, computational resources allow the reduction of these simplifications. The most recognized methods of algebraic

5. Materials Selection Using a 2-tuple Linguistic Multi-criteria Method
The materials selection can affect the design component radically, with effect on the manufacturing systems efficiency, environmental impact issues, and customer satisfaction. There are different methods employed for materials selection; however, two steps are usual for most of these methods: screening and ranking. The ranking step identifies among materials

6. A Computational Framework for Daily Power Flow Analysis Considering Photovoltaic Distributed Generation
Abstract In Brazil, the demand for the acquisition and installation of photovoltaic systems has grown exponentially and, with that, the importance of studies considering their effects on the distribution grids power flow also grows. Due to the intermittent nature of photovoltaic generation, it is important to approach the analysis in a discrete way, taking i

7. Computational algorithm for stability analysis of distribution networks with distributed generation
Abstract With the insertion of distributed generation in distribution networks, security analysis becomes crucial, in islanded operation or when the system is connected to the grid. Dynamic stability analyses are necessary in order to achieve minimum levels of security and reliability. Such analyses are obtained through the solution of the algebraic-differen

8. Experimental and Computational Studies of the Adsorption of Furan, Pyrrole, and Thiophene on Hydroxyapatites in a Single and Ternary Component
Non-doped (Hap) and doped hydroxyapatites with Cu2+ and Fe2+ were synthesized and used to study the adsorption of furan (Fur), pyrrole (Pyr), and thiophene (Thi) in single and ternary component systems. Spectroscopic data and N2 isotherms indicated there were no structural alterations in Hap with the incorporation of Cu2+ and Fe2+. For both single and ternar

9. ROBUST METHODOLOGY FOR DETECTION OF SPIKES IN MULTIBEAM ECHO SOUNDER DATA
Abstract Currently, during the operation in shallow waters, scanning systems, such as multibeam systems, are capable of collecting thousands of points in a short time, promoting a greater coverage of the submerged bottom, with consequent increase in the detection capacity of objects. Although there has been an improvement in the accuracy of the depths collec

11. Artificial intelligence, machine learning, computer-aided diagnosis, and radiomics: advances in imaging towards to precision medicine
Resumo A disciplina de radiologia e diagnóstico por imagem evoluiu sobremaneira nos últimos anos. Temos observado o aumento exponencial do número de exames realizados, a subespecialização das disciplinas médicas e a maior acurácia dos métodos, tornando um desafio para o médico radiologista “saber tudo sobre todos exames e regiões”. Além disso,

12. Análise Descritiva do Tema Deficiência nos Currículos de Graduação da Universidade Federal do Rio Grande do Norte
RESUMO A educação pode contribuir com a inclusão de pessoas com deficiência na sociedade em pelo menos duas frentes. De um lado, é preciso garantir acesso, permanência e conclusão dessas pessoas nos sistemas de ensino. De outro, é preciso ensinar pessoas sem deficiência a conviver e lidar adequadamente com pessoas com deficiência. O desafio de form
