Oxygen saturation of small arteries and veins (20-500 micron) was determined microspectrophotometrically in the hearts of 12 pentobarbital-anesthetized open-chest dogs. Hearts were removed, quick frozen in liquid propane, and O2 saturation was determined in blood vessels on a regional basis between and within ventricular walls. No significant differences existed in arterial O2 saturation betwee...

Abatrati-An analysis is presented of a binary film with fog formation and a negligible induced velocity (traditionally referred to as “Stefan-Nusselt flow”). The governing equations of energy and diffusion, coupled with the saturation con@on, are solved and analytical correction factors are derived. Subsequently, the “negligible induced velocity” (NIV) fog film model is applied to channel flow,...

Abstract Analytical modeling of the PMSM often involves many simplifying assumptions. The model thus obtained is a model where the physical phenomena and dynamics are neglected during the identification of the process such that the saturation of the magnet circuit and the skin effect. However, the variation of stator resistances, cyclic inductances and moment of inertia due to the temperature a...

Electrorheology (ER) denotes the control of a material's flow properties (rheology) through an electric field. We have fabricated electrorheological suspensions of coated nanoparticles that show electrically controllable liquid-solid transitions. The solid state can reach a yield strength of 130 kPa, breaking the theoretical upper bound on conventional ER static yield stress that is derived on ...

We investigate the dissipative loss in the ±J Ising spin glass in three dimensions through the scaling of the hysteresis area, for a maximum magnetic field that is equal to the saturation field. We perform a systematic analysis for the whole range of the bond randomness as a function of the sweep rate by means of frustration-preserving hard-spin mean-field theory. Data collapse within the entir...

In this paper, a novel tuning technique for the current and speed controllers of the Brushless DC (BLDC) motor derive system is presented. The parameters of PI controllers in the inner current control loop and outer speed control loop which vary with the operating conditions such as variation of temperature and saturation phenomena or load torque changing of the drive are adjusted in order to m...
