A novel mesh-free methodology for the coupled magnetic field-circuit simulation of power transformers is presented in this paper. The proposed methodology employs equivalent models for the conductors and the iron core, w...

The transesterification reaction of soybean oil with methanol is studied with different gAl2O3 heterogeneous catalysts. The catalysts used are K-gAl2O3, Na-gAl2O3, Li-gAl2O3, Ca-gAl2O3 and Ba-gAl2O3 both 5% and 10% in me...

The standard method for spectrum analysis is the Discrete Fourier Transform(DFT), typically implemented using a Fast Fourier Transform (FFT) algorithm. However, certain applications require an on-line spectrum analysis o...

Relative vibration between two flexible subsystems can be detrimental to the performance of many engineering applications, such as optics-based instruments, machine tools, or adjacent industrial structures sharing piping...

This chapter introduces the most relevant concepts about wine field, including terroir, manufacturing process and the Wine Protected Designation as a way ofauthentication. Contents of molecular organic acids, volatile sp...
