A variable neutral density filter, as we’ve alluded to elsewhere in this guide to the best variable ND filters, controls ALL of the light that enters your camera. Unlike a fixed ND filter that reduces light levels by a stop, a variable ND filter allows you more control over these light...
Until now GND filters come in fixed values. Users need to go through multiple GND filters based on the shooting environment. Meanwhile there are no fractional stop GNDs. 播放 Adjustment of transition area is shown at 0:23. Unedited UHD 4k version With a PowerGXND variable GND filter, all...

If |Ej| > λand Ej< 0 the variable is selected since it has a significant effect on the reduction of the prediction error value. These are the “fixed” variables. • If |Ej| > λand Ej> 0 the variable is discarded since it has a significant effect on the increase of the predict...
fixed time. This allows the detector signal, without an m/z species impinging on the detector and causing an ion current, to decay to a background noise value. However, this is not optimal since the fixed time may be too short, causing the carry over errors, or the fixed time may be...
(i.e. statistical significance of association between the SNP and phenotype passes the filter parameterp). Since the ability to identify cases of misclassification improves with the phenotype predictive ability of the set of SNPs selected as input, if the selected SNPs have weak associations we ...
1. A control device for an infinitely variable transmission for a vehicle, the infinitely variable transmission comprising an input shaft, a continuously variable transmission which outputs the rotation of the input shaft at an arbitrary speed ratio, a fixed speed ratio transmission which outputs the...
The variable admittance controller proposed in this paper can not only overcome the limitation of the fixed admittance model but also improve the smoothness of the traditional variable admittance model. From the aspect of intuitive perception, participants comment that it is easy to accelerate but ...
However, the basic WNN offered a fixed set of weight during the training process and was unable to obtain the characteristics of all input data. It was difficult to learn the input data deeply with fixed weight coefficients if the data were distributed in a wide domain [24]. Then, the ...
