Abstract A new configuration for realizing high input impedance voltagemode biquadratic filters with two inputs and one output is presented. The proposed configuration uses two second generation current conveyors (CCII’s) of different polarity, two resistors, and two capacitors. The present configuration is capable of realizing band pass (BP), all pass (AP), and notch filter functions. The circ...
The aim of the BEST-project is to support laymen in judging their legal position through intelligent disclosure of case-law in the area of Dutch tort law. A problem we have to face in this context is the discrepancy between the terminology laymen use to describe their case and the terminology found in legal documents. We address this problem by supporting users to describe their case in common ...
International Digital Divide is an imbalance state of ICT penetration between countries. This paper analyzes the current status and trends of international digital divide, adopts Gompertz technology diffusion model to verify the determinants of ICT penetration level and diffusion rate separately. Finally, China should use “policy levers” to strengthen international trade cooperation, improve th...
BACKGROUND The utility of combined oesophageal pressure-impedance recording has been enhanced by automation of data analysis. OBJECTIVE To understand how oesophageal function as measured by automated impedance manometry (AIM) pressure-flow analysis varies with bolus characteristics and subjective perception of bolus passage. METHODS Oesophageal pressure-impedance recordings of 5 and 10 ml l...
Inductive plethysmography and impedance pneumography are two non-invasive technologies for measuring respiratory function. The following report describes the advantages of inductive plethysmography, which include greater accuracy and sensitivity; the ability to assess thoracoabdominal coordination; and the minimization of motion artifact. Together, these properties make inductive plethysmograph...
In this paper, a new impedance function is proposed to achieve accurate force tracking under the presence of uncertainties in robot dynamics and environment models. The new impedance function is formulated on the basis of PID control of the force tracking error which compensates for the unknown environment stiiness and position. The robot dynamics uncertainties are compensated by a simple time-...
A new current-mode (CM) single input three outputs (SITO) multifunction filter topology is presented, which employs only three FTFNs or OFAs and five passive elements. From this topology, two filter circuits can be derived selecting the passive elements properly. The proposed filter realizes three filter functions simultaneously all at high impedance outputs. No component matching is required a...
Electrical impedance of biological matter is known as electrical bioimpedance or simply as bio-impedance. Bio-impedance devices are of great value for monitoring the pathological and physiological status of biological tissues in clinical and home environments. The technological progress in instrumentation has significantly contributed to the progress that has been observed during the last past ...
Abstract. We consider the inverse obstacle scattering problem of determining both the shape and the “equivalent impedance” from far field measurements at a fixed frequency. In this work, the surface impedance is represented by a second order surface differential operator (refer to as generalized impedance boundary condition) as opposed to a scalar function. The generalized impedance boundary co...
