In earlier studies we found that the three-element windkessel, although an almost perfect load for isolated heart studies, does not lead to accurate estimates of total arterial compliance. To overcome this problem, we introduce an inertial term in parallel with the characteristic impedance. In seven...
The DB stubs-loaded MN features an open-stub and a shorted-stub in parallel with total length 位1/4 (位1 is guided wavelength from lower f1 of two matching frequencies). The considered load has frequency-dependent complex impedance at two uncorrelated frequencies (f1, f2). Design equations ...

Moreover, to ensure best possible acoustic signal propagation, we opted for a thin GL, whereas water has an acoustic impedance of 1.5 × 106 kg m−2 s−1 and an acoustic attenuation coefficient at 0.0022 db cm−1 MHz, gold exhibits values of 62.6 × 106...
What is Transfer Impedance in a PDN?We often talk about impedance in a PDN, but we always refer to self impedance. Here’s what you need to know about transfer impedance in your PCB.Read Article What is Spreading Inductance?The spreading inductance of a plane pair has a simple meaning, ...
The infant was dressed (with arms and legs covered) and swaddledto ensure that both arms and legs remained parallel with the main axis of the body and that their movement was restricted. TOBEC measurements were made in a modified EMME M-60 instrument (DICKEY-john, Auburn, IL) as pre- ...
Preliminary studies showed more accurate predictions of BCM when parallel-transformed values of reactance were used rather than the values reported by the bioelectrical impedance analyzer. Modeling equations derived after logarithmic transformation of height, reactance, and impedance were more accurate ...
since there is impedance matching requirement for LVDS, and if you just parallel 2 LVDS input (the MIPI-paralle converter, and the FPGA) this may upset the balance and it will not work. let our engineering look at this if it will work. 喂吴先生,也,这可能不是一样平直向前的,象我提及...
Unfortunately, distributed generation (DG) inherently leads to weak systems because the source impedances of small generators are large, that is, they cannot supply a large current (ideally infinitely large) during transient operation. This application example studies the power-factor correction for a...
Finally, considering MMs in terms of the effective and m, they can provide the impedance matching of absorbing structures with free space. Perfect absorption in metamaterials has been demonstrated in far-infrared11, mid-infrared12, near-infrared13 and visible14 ranges. Last decade hyperbolic ...
