PURPOSE Successful management of anal fistulas depends upon accurate assessment of the primary tract and any secondary extensions. Preoperative imaging has, to date, been disappointing. METHODS A prospective study of 35 patients with a clinical diagnosis of fistula-in-ano was performed comparing magnetic resonance imaging with the independently documented operative findings. Magnetic resonanc...
Recently, increasing of non-linear loads in the power distribution network has been increased harmonics in these networks. The harmonics problems get worse and complicated by installation of power factor correction capacitors and filters. But the Distributed Generations (DGs) interface inverters with properly control can help to improve power quality, harmonic compensation and voltage unbalance...
This paper revisits the resonant behavior of a harmonically-forced Duffing oscillator with specific attention to phase resonance and its relation amplitude resonance. To this end, different families resonances, namely primary (1:1), superharmonic (k:1), subharmonic (1:ν) ultra-subharmonic (k:ν) resonances are carefully studied using first higher-order averaging. When lag is calculated between k...
