The interest in motor drive systems with a number of phases greater than three has increased, mainly in high-power industrial fields due to their advantages compared with three-phase drive systems.In this paper, comprehensive mathematical modeling of a five-phase matrix converter (MC) is introduced.Besides that, the direct and indirect space vector
A theoretical analysis upon the GF MUESLI four-dimensional (4D) spatio-temporal temperature dependent dynamics of 888 nm pumped Nd:YVO 4 dual-rod laser is established, which is valid in both continuous-wave (CW) and acousto-optic (AO) Q-switched pulse lasers conditions.Our model can accurately solve the 4D thermal generation and temperature evoluti
Abstract Background Studies involving the built environment have typically relied on US Census data to measure residential density.However, census geographic units are often unsuited to health-related research, especially in rural areas where development is clustered and discontinuous.Objective We evaluated the accuracy of both standard census meth
A well-designed learning curve is essential for the acquisition of laparoscopic skills: but, are Towel there risk factors that can derail the surgical method? From a review of the current literature on the learning curve in laparoscopic surgery, we identified learning curve components in video laparoscopic cholecystectomy; we suggest a learning cur
