PARTIAL DISCHARGES IN ELECTRICAL MACHINES FOR THE MORE ELECTRIC AIRCRAFT—PART I: A COMPREHENSIVE MODELING TOOL FOR THE CHARACTERIZATION OF ELECTRIC DRIVES BASED ON FAST SWITCHING SEMICONDUCTORS

The arrival on the market of new power devices based on wide bandgap semiconductors has raised a relevant interest due to their superior properties compared to conventional technologies.On the other hand, these devices are inherently characterized by high rates of voltage changes over time, which may result in reliability challenges in electric dri

Urban horticulture is not as new as many people think.Throughout history, different techniques have been used to ensure sustainable urban agricultural production.A 2 Way 8" good example of this is the chinampa system, which was developed during the time of the Aztecs in the region of Lake Xochimilco, south of Mexico City.A chinampa is a raised fiel

As a fundamental principle of natural resource management, sustainability encompasses a range of interrelated concepts, including operational efficiency, environmental effect minimization, Gift Wrapping and socioeconomic impact analysis.Microalgae have the capability to minimize CO2 emissions while also generating a large volume of oil, which might

In most researches in the area of risk management, the result stops at proposing the mitigation strategies.The number of researches on associating cost analysis into the risk management process is very limited.This paper proposes a practical process on how cost analysis can be associated into the risk management process especially in the area of ma
