This chapter is devoted exclusively to Alamán’s efforts between the early 1820s and about 1830 to revive the Mexican silver mining industry on the basis of massive capital injections by British investors. The company he managed in Mexico between about 1825 and 1830 was the United Mexican Mining Association, one of the largest among a flock of such ...

Electric submersible pump broken shaft fault diagnosis based on principal component analysis
, 2020Electric Submersible Pump (ESP) is currently widely employed to help enhance production for nonlinear-flowing well with high production and high water cut well. However, ESP broken shaft is common in the oil industry. The broken shaft leads to production

Soil Dynamics and Earthquake Engineering, 2019
Due to the special configurations of the shaft-tunnel junction, discrepant responses of the shaft and the tunnel will arise when earthquakes strike. This paper presents shaking table tests addressing this discrepancy and its influence on the structures ...

Analysis and Suppression of Shaft Voltage in SiC-Based Inverter for Electric Vehicle Applications
IEEE transactions on power electronics, 2019SiC mosfets allow a higher frequency, lighter weight inverter over their Si counterparts for electric vehicle (EV) applications. However, using SiC-based EV traction inverters is likely to increase the shaft voltage in an ac motor drive system, which ...
