Inverse Transient Analysis (ITA) is a powerful approach for leak detection of pipelines. When the pipe transient flow is analyzed in frequency domain the ITA is called Inverse Frequency Response Analysis (IFRA). To implement an IFRA for leak detection, a transient state is initiated in the pipe by fast closure of the downstream end valve. Then, the pressure time history at the valve location is...
Abstract Background and purpose: To determine the effect of intrasphincteric botulinum toxin injection to treat internal anal sphincter achalasia. Materials and methods: Twenty patients (11 boys, average age 4.95± 2.47 years) with definite diagnosis of internal anal sphincter achalasia received 20 units of botulinum toxin injection in 4 points of the internal anal sphincter (totally 80 unit...
Space Vector Current Regulators (SPCR) have low harmonic currents in steady state, but they have slower transient response compared to other control methods such as hysteresis current regulator. In this paper a new method is proposed to improve transient response of SPCR compared to conventional methods. The proposed technique is based on adjustment of zero vector time intervals and modifying t...
Abstract: In this paper, we show that adaptive controllers designed using the standard backstepping technique proposed in Krstic [1995] globally stabilize a class of uncertain systems with unknown input time delay and unmodeled dynamics. As such systems belong to nonminimum phase systems and thus our result extends the class of systems stabilizable from minimum phase systems when the standard b...
