Fuel cells have the potential to provide clean power for a variety of uses including stand-alone residential power. But to increase the acceptance of fuel cells for off-grid generation, the cost of the energy management system must be greatly reduced. Of the many ways to accomplish this, this paper looks at reducing cost through topology changes and elimination of current sensors. A dual 2.5kW non-isolated bidirectional boost converter is designed and analyzed. The various bidirectional boost topologies are compared on cost and ability to meet the specifications.

As normas de gestão ambiental têm por objetivo prover as organizações dos elementos necessários para implantação de Sistemas da Gestão Ambiental (SGA) que possam ser integrados a outros requisitos da gestão, e auxiliá-las a alcançar seus objetivos ambientais e econômicos. A Unidade de Produção de Hexafluoreto de Urânio USEXA, do Centro Tecnológico da Marinha em São Paulo - CTMSP, será a primeira planta industrial da etapa de conversão do ciclo do combustível nuclear (produção de hexafluoreto de urânio UF6) do Brasil, permitindo que seja agregado valor ao minério de urânio.

Abstract:

O objetivo do desenvolvimento do projeto foi minimizar uma das principais desvantagens no uso do gás natural veicular, que é a perda de potência, e aumentar sua eficiência volumétrica através da construção de um circuito eletrônico capaz de gerenciar de forma eficiente a injeção do gás. O aumento do rendimento é obtido através do gerenciamento eficiente da mistura ar-combustível utilizando um sistema de malha fechada. O gerenciamento da relação de potência e economia é conseguido com o uso simultâneo de gás natural e o combustível líquido. Nos sistemas de conversão atuais e nos veículos origin

Abstract:

Human society releases greenhouse gas emissions to the atmosphere while providing housing, heat, mobility and industrial production. Man-made greenhouse gas emissions are the main causes of climate change, coming mainly from burning fossil fuels and land-use changes. Sustainably managed forests play an important role in climate change mitigation with the prospect of sustainably providing essential materials and services as part of a low-carbon economy, both through the substitution of fossil-intensive fuels and material and through their potential to capture and store carbon in the long-term p

Abstract:

Optimal control of energy flows in a Hybrid Electric Vehicle (HEV) is crucial to maximising the benefits of hybridisation. The problem is complex because the optimal solution depends on future power demands, which are often unknown. Stochastic Dynamic Programming (SDP) is among the most advanced control optimisation algorithms proposed and incorporates a stochastic representation of the future. The potential of a fully developed SDP controller has not yet been demonstrated on a real vehicle; this work presents what is believed to be the most concerted and complete attempt to do so.

Abstract:

Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. • Air pollution, noise, congestion and land-use may jeopardise public health and quality of life, especially in urban areas. In a sustainable urban transport system most trips are made with public transport because high convenience and comfort makes travelling with public transport attractive. In terms of emissions, including noise, the veh
