in this work, polypyrrole/ceo2 nanocomposite (nc) was synthesized in the presence of methylorange as a reactive self-degraded soft template. the field emission scanning electron microscopy(fesem) images indicate that the ceo2 nps have a nucleus effect and cause a homogenous ppycore–shell type morphology with an encapsulation of the ceo2 core by the ppy shell. the effect ofnc on acrylic waterbor...

OBJECTIVE To utilize real-time electrical impedance tomography to guide lung protective ventilation in an animal model of acute respiratory distress syndrome. DESIGN Prospective animal study. SETTING Animal research center. SUBJECTS Twelve Yorkshire swine (15 kg). INTERVENTIONS Lung injury was induced with saline lavage and augmented using large tidal volumes. The control group (n = 6) ...

The purpose of this paper is to propose the adaptive expert masssage robot using a multi-fingered robot. Towards this goal, the present paper gives a modeling of human skin muscle through robot perception of impedance, and control strategy using impedance control to implement adaptive control system, even if human condition is changed. The model validity is demonstrated via many experiments by ...

Impedance measurements provide a useful probe of the physics of bolometers and calorimeters. We describe a method for measuring the complex impedance of these devices. In previous work, stray impedances and readout electronics of the measurement apparatus have resulted in artifacts in the impedance data. The technique allows experimenters to find an independent Thevenin or Norton equivalent cir...

Skin impedance at acupuncture points (APs) has been used as a diagnostic aid for more than 50 years. In this study, we have a diagnostic tool (JXT-2008) to measure the skin impedance of ear APs of 30 breast cancer patients and the corresponding skin impedance of ear APs of 30 healthy humans, and then we compared these changes in ear AP impedance in breast cancer patients and healthy individuals.

The transient response of passivated metallic electrode system under potential step was analyzed based on a linear model, and a technique for calculating the parameters characterizing the growth and dissolution of passive film was proposed. It is believed that the information which is expected to be gained from the impedance measurement can be obtained by this technique and that this technique ...

KŘIVÁNEK, I.: Impedance pattern of vaginal and vestibular mucosa in cyclic goats. Acta univ. agric. et silvic. Mendel. Brun., 2008, LVI, No. 4, pp. 109–114 The changes of vaginal and vestibular impedance during the oestrous cycle in goats were examined. The onset of oestrus was teased with a buck once a day during the experiment. Impedance was measured by a four-terminal method. The vaginal imp...

Mechanical impedance is the dynamic generalization of stiffness, and determines interactive behavior by definition. Although the argument for explicitly controlling impedance is strong, impedance control has had only a modest impact on robotic manipulator control practice. This is due in part to the fact that it is difficult to select suitable impedances given tasks. A spatial impedance control...
