The ion selectivity of nanochannel due to the wall surface charges is capable of inducing strong coupling between fluidic and ionic motion within the system, which has been overlooked in the study of nanofluidics. This interaction opens up the prospect of operating nanochannel as nanoscale devices for electrokinetic energy conversion. However, the very short channel lengths make the ionic movement...
An equivalent electric circuit model is used to interpret the dynamic behavior of a photo-voltaic (PV) panel with a power electronic converter. The power electronic converter used for maximum power point tracking (MPPT) draws rippled currents from the PV panel. The circuit model is derived on basis of the static single-diode model, in which, the threshold voltage is approximately identical to the...
In this paper, design and characterization of a 18 V switched-capacitor CMOS interface circuit for the closed-loop operation of a capacitive accelerometer is presented. The pendulous silicon accelerometer operates in atmosphere pressure and is designed for non-peaking (low-Q) response with a sensitivity of 0.5 pF/g without vacuum packaging. Test results shows that a full scale acceleration of plusmn15...
It is necessary to analyze the anti-terrorism performance of Taiwanpsilas security system after September 11, 2001 attacks. We use three stage data envelopment analysis model that Fried et al. (2002) developed, getting intelligence performance of the Investigation Bureau of the Ministry of Justice, to discuss the ability of anti-terrorism in Taiwanpsilas national security system. Putting 10 outputs,...
