Bias

1. In statistics, a circumstance leading to inaccurate results because of conscious or unconscious manipulation of data. Bias is anything that reduces the randomness of the sample being tested.

2. Anything that affects a decision other than facts. For example, a company may be disinclined to expand into an area of town because it is perceived as dangerous, whether or not it actually is. Bias is thought to reduce efficiency. See also: Behavioral economics.

4, is showed the variation of oscillation frequency obtained versus the variation of bias voltage. In response to a sweep of the bias voltage between 0.7 and 1.2 V, the operation frequency increases progressively from 6138 to 7222 MHz.
The spectra were obtained by changing the polarity of the bias voltage to evaluate the difference in charge transport properties between electrons and holes.
Because the LC bias voltage is loaded along the z-direction, the LC molecules are also along the z-direction.
The left part of Figure 5 depicts a bias circuit that is used to provide three constant bias voltages, [V.sub.1], [V.sub.2], and [V.sub.3].
A Bosch resistive particulate matter sensor from a MY15 Ford F-series truck was installed after the DPF, and the manufacturer supplied control module for the PM sensor was replaced with a rapid prototype controller that facilitated non-standard transitions between measurement (bias voltage on) and regeneration (bias off, heater on) states.
The J-V curves for the n-type [beta]-Fe[Si.sub.2]/p-type Si heterojunctions grown by RFMS on a logarithmic scale as a function of temperature ranging from 300 down to 20 K under forward and reverse bias conditions in the applied bias voltage range of -1.5 to +1.5 V are displayed in Figure 3.
For MOSFET under low temperature condition, the resistance value for each MOSFET highly depends on its bias voltage which varies rapidly.
To understand the polarization behaviors of C[H.sub.3]N[H.sub.3]Pb[I.sub.3] films, we applied a DC bias voltage between the C[H.sub.3]N[H.sub.3]Pb[I.sub.3] film and the conductive tip during the AFM measurement; the DC biases voltages were set to 0 V, +3 V, +6 V, and -10 V, respectively.
found that the nanoscale friction properties of a Si (100) sample can be manipulated significantly by the simple application of a bias voltage [18].
Once the bias voltage is greater than the threshold voltage, the resonant frequency changes less drastically with changes in voltage, but the resonance quality steadily increases as the voltage continues to increase.
SCM uses a metalized probe tip to bias the semiconductor in the depletion mode and to measure the differential capacitance between the probe and the semiconductor material as a function of the bias voltage [5-9] (see Fig.
