This paper analyzes the resonance phenomenon that occurs in the uncontrolled slave motor of two surface mounted permanent magnet synchronous motor (SPMSM) drives, connected in parallel to a single inverter. This phenomenon is observed when the inverter is controlled by the master-slave method, due to the differences in parameters between the two motors and(More)
A mixture of tiletamine, a dissociative anesthetic, and zolazepam, a minor tranquilizer, has been widely used as an anesthetic or an immobilizing agent in a variety of animal species. However, interestingly, their pharmacokinetic behaviors have been published only in polar bears and pigs. In this study, we introduce a sensitive liquid chromatography/tandem(More)
This study was to determine the daily fluctuation of serum thyroxine (tT4), free thyroxine (fT4), 3,5,3'-triiodothyronine (T3) concentrations in healthy dogs. Thyroid function of these dogs was evaluated on the basis of results of TSH response test. Samples for the measurement of serum tT4, fT4, and T3 concentrations were obtained at 3- hour intervals from(More)
Trans epidermal water loss (TEWL), skin hydration status and pH were determined in 14 skin regions of five healthy male Beagle dogs (2-4 years) both before and after anaesthesia. Trans epidermal water loss was highest for the footpad and head and lowest for the inguinal region. Skin hydration status was higher in the ear but did not vary significantly in(More)
This paper presents an application of a discrete derivative method with a new frequency mapping technique for adaptive-notch-filter (ANF) based resonance suppression in an actual industrial servo system. An ANF includes a frequency estimator which estimates the frequency of input signal in real time. A new discrete derivative method, which utilizes a(More)
Manufacturing demands have increased in recent years, requiring a tack time a few tens of milliseconds to assembly machines with vibrational modes of less than a couple of hundreds of Hz. For typical high-frequency range (approximately 800 Hz) vibrations, notch filters with a depth of 1.0 are successfully used for vibration suppression. However,(More)
This paper presents a method to enhance robustness in sliding mode control (SMC) combined with decoupled disturbance compensator (DDC). More specifically, a gain selection method for the DDC in industrial servo systems with unknown inertia is developed. The SMC with DDC method is a well-known robust control method which is effective for slowly-varying and(More)
This study was performed to investigate the antioxidant and hepatoprotective effects of fermented red ginseng (Panax ginseng C.A. Meyer; FRG) on high-fat diet-induced hyperlipidemia in rats. Sprague-Dawley rats were divided into four groups of seven: normal control, NC; high-fat diet control, HFC; high-fat diet-0.5% FRG, HF-FRGL; and high-fat diet-1% FRG,(More)
This paper presents an application of the command shaping method to industrial servo systems. The command shaping method, such as input shapers and bi-quad notch filters, is a well-known control technique for reducing residual vibrations. An input shaper cancels out the vibration using the convolution of a sequence of impulses with a reference command. A(More)
