Sensitivity constant

Ks is the sensitization constant and in the absence of other complications, it should be equal to Kq.

The positional resolution is inversely proportional to the sensitivity constant S = RC which means that the resistivity of the wire has to be high. Again, a choice has to be made between a good spatial resolution and a high counting rate capability. 

The microwave conductivity is proportional to the number of free electronic charge carriers multiplied by their respective mobilities (the contribution of ions and dipoles can be neglected in a first approximation.). The microwave sensitivity constant S must be obtained by calibration. The potential-dependent photoinduced microwave conductivity (PMC) of a semiconductor resulting from illumination has been calculated analytically as a function of the interfacial charge-transfer and surface recombination rates (Schlichthorl and Tributsch, 1992). The starting point is the general set of equations of the form... 

A sensitivity analysis has been made of the calculated results to the. values of the equation constants using benzene data. The most sensitive constant is (u°/k). A variation of 1% from its optimal value increases the error of calculated vapor pressures by 6%, and of calculated liquid... 

Both single-Knudsen cell and multiple-Knudsen cell systems can be used for thermodynamic measurements of metals and alloys. The critical consideration is the sensitivity constant Sa from Equation 48.1 ... 

We used a LB 9505 multidetector unit for the simultaneous and continuous recording of luminescence from six samples (Berthold and Maly 1987). This instrument is equipped with six rubidium-bialkali photomultiplier tubes placed in close proximity to the vials inside six independent counting chambers. Reflectors ensure optimum counting efficiency. Each measuring chamber has its own temperature control. Since the results from all six detectors should allow direct comparison, they were standardised by determination of its individual sensitivity constant (X-factor). 

Using the same settings as obtained in step 2, run the same procedure on pure water. The blank should be very small, if detectable at all. Usually with the 500mL vessel there is a small but significant blank (ca. 0.3 ng). Record this blank and convert it to concentration units using the sensitivity constant from step 2. 

Rho describes the sensitivity of the new reaction to substituent effects relative to the influence of the substituent on the ionization of benzoic acid. It is called the reaction constant or sensitivity constant for each new reaction under study. The following values ofp lead to the associated conclusions ...

With the proper fine-tuning of the sensitivity constants of the recommended methods and consequently the sensitivity, the user can choose the method which is most suitable to the particular process conditions and environment. The data bounding method was tested by Sebastian et al. with nuclear inventory data and found to be very successful. We have continued this work with robust smoothing methods and have found these to be successful as well. These methods also work for general SPC. 

This equation relates the mass change of the adsorbed layer to the frequency shift of the quartz crystal, which forms the fundamental basis of the highly sensitive QCM mass detection technique. Here, C is the mass sensitivity constant of 17.7 ng cm Hz for a 5 MHz quartz resonator [12].
