1. Technical and economic viability of the installation of a hybrid solar-wind generation system in a Brazilian industry
Abstract The demand for electricity is growing worldwide. At the same time, the non-renewable natural resources that account for a large proportion of the global energy matrix are rapidly depleting, which will pose a major challenge in the near future. Therefore, micro-grid models that use renewable energy sources, such as solar and wind, are rapidly develo

2. Estimativa do potencial de recuperação energética de resíduos sólidos urbanos usando modelos matemáticos de biodigestão anaeróbia e incineração
RESUMO Atualmente, um dos grandes problemas enfrentados pelos gestores de resíduos sólidos urbanos (RSU) é a disposição final dos resíduos gerados por sua população. As disposições de resíduos devem ser feitas em espaços e sob condições adequados de modo a minimizar os impactos socioeconômicos e ambientais. Nesse contexto, este artigo teve por

3. Proposal for a Monitoring and Dispatch System for Distributed Micro-Generation of Renewable Energy in Virtual Energy Centers
ABSTRACT The creation and updating of ANEEL (National Electricity Regulatory Agency) regulatory resolution on distributed generation provided a new business environment for the electricity sector, as well as enabling consumers to generate energy. In this context, distributed microgeneration plants management is a challenge, mainly for electric power distribu

4. Combined Cycle Performance Evaluation and Dynamic Response Simulation
ABSTRACT Power plants operating in combined cycle present higher thermal efficiency (over 60%) and increased power generation when compared to traditional simple cycles, such as gas or steam turbines operating alone. Considering that the power plant evaluated in this paper is already operational, a further development concerning to the power plant control sy

5. Análisis de tasas y modelos para generación de viajes en hipermercados y supermercados
The location of commercial trip generation hubs produces urban impacts in the area of influence since they increase the number of vehicle trips that affects environment and quality of life. For better understanding of this phenomenon, it is reported in this article an analysis of trip generation rates and models in hypermarkets and supermarkets considering d

6. Decomposition approach for generation and transmission expansion planning with implicit multipliers evaluation
In an electric power systems planning framework, decomposition techniques are usually applied to separate investment and operation subproblems to take benefits from the use of independent solution algorithms. Real power systems planning problems can be rather complex and their detailed representation often leads to greater effort to solve the operation subpr

7. Network modelling of palm biodiesel plants to supply the isolated electric power systems of Pará state
Despite the great advance brought by the National Interconnected System (NIS), which is able to provide clean hydroelectric power to almost all Brazilian customers, there are still cities supplied by power generated from fossil fuel, which are subsidized by taxes, they are called Isolated Electric Power Systems (IEPS). Pará State, that has 34 cities with IE

8. Desenvolvimento de modelos e algoritmos sequenciais e paralelos para o planejamento da expansão de sistemas de transmissão de energia elétrica / Development of mathematical models, sequential and parallel algorithms for transmission expansion planning
The main objective of this study is to propose a new methodology to deal with the long-term transmission system expansion planning with multiple generation dispatch scenarios problem (TEP-MDG). With the methodology proposed in this thesis we aim to build expansion plans with minimum investment cost and also capable of meeting the new demands of modern electr

9. Green-Markov models - new optimization strategies: a case study for user allocation in co-channel macro/femto networks
The femtocell concept aims to combine fixed-line broadband access with mobile telephony using the deployment of low-cost, low-power third and fourth generation base stations in the subscribers' homes. While the self-configuration of femtocells is a plus, it can limit the quality of service (QoS) for the users and reduce the efficiency of the network, based o

10. A swirler stabilized combustion chamber for a micro-gas turbine fuelled with natural gas
Micro-gas turbines are a good alternative for on-site power generation, since their operation is very reliable. The possibility of operating with various fuels increases versatility and, as a result, the usage of these devices. Focusing on a performance improvement of a tri-fuel low-cost micro-gas turbine, this work presents investigations of the inner flow

The Brazilian publishing market in expansion since the first decades of the XX Century has incorporated at its own manner the speeches produced either by the hygienist movement as well as by those who understood upbringing as a way to regenerate a nation, leading it into progress and modernity. Written mostly by pediatricians, mother guidebooks were part of

12. Busca heurística e inferência de parâmetros cinéticos de reações de hidrotratamento de óleo diesel a partir de dados experimentais escassos
Currently, the amount of contaminants (such as sulfur, nitrogen and aromatics) in diesel oil is strictly controlled, due to their impact on pollutant emissions. The most important process used to meet fuel specifications regarding contaminants is the catalytic hydrogenation, specifically hydrotreatment (HDT). Optimization of the HDT process can benefit from
