Introduction: With the introduction of high-speed traffic there is an increased consumption of traction current by new types of rolling stock. This issue is important, as high levels of traction currents can have not only prevents, but also a dangerous im... see more

For an energy-harvesting wireless transmission system, considering that a transmitter which can harvest energy from nature has two kinds of extra energy consumption, circuit consumption and storage losses, the optimization models are set up in this paper ... see more

Inter-turn short circuit of field windings (ISCFW) may cause the field current of a generator to increase, output reactive power to decrease, and unit vibration to intensify, seriously affecting its safe and stable operation. Full integration of mechanica... see more

Electric vehicles promise to contribute to the achievement of a more sustainable transport system, e.g. through reducing energy consumption and CO2 emissions. For the assessment of electric vehicles’ environmental impact and for decisions on their operati... see more

This study aimed to analyze the gap between the concepts of current and voltage between junior high school students and teachers in Indonesia. The number of samples was 720 students, class X, and 527 teachers who were selected by purposive sampling diagno... see more

For the footwear industry, Sobral, in Ceará, stands out as the most expressive productive territory, a fact that is justified by the location of Grendene's production units. This article aimed to analyze the general aspects of territorial interactions of ... see more

Electricity consumption expands every year. However, in Indonesia, electricity is still highly dependent on conventional energy sources such as coal. A microbial fuel cell (MFC) is one of the alternative inventions that consists of a series of tools which... see more

The Energy dissipation in conventional CMOS circuits can be minimized through adiabatic technique. By adiabatic technique dissipation in PMOS network can be minimized and some of energy stored at load capacitance can be recycled instead of dissipated as h... see more

O fenômeno global de consumo de objetos chamados aqui made in China - de baixo valor, baixa qualidade e utilidade reduzida -, que compõem certo universo kitsch contemporâneo, é o foco deste texto. O objetivo é abordá-lo do ponto de vista das práticas de c... see more
