functional datawhite noiseminimum distanceWe propose a new procedure for white noise testing of a functional time series. Our approach is based on an explicit representation of the L2-distance between the spectral density operator and its best (L2-)approximation by a spectral density operator ...
There are 2 distinct functional types of noise reduction systems, the single ended system and the codec or dual ended system. The purpose of a single ended device is to remove noise or other artefacts that are already present in a signal while the purpose of codec is to minimise the generat...
We observe that for equivalent function, more complex networks exhibit a reduction in intrinsic noise. This is not easily attributable simply to the increased total molecule counts18,19. First, although there are more total mol- ecules in more the complex networks, each species is kept at ...
Position emission tomography (PET) is used to assess the functional activity of the human auditory brain; however, the activity detected by PET could be af... K Kim,RF Burkard,AH Lockwood,... - 《Scandinavian Audiology》 被引量: 10发表: 2000年 Active noise reduction stethoscopy for lung ...
The spectral analysis of signals is currently either dominated by the speed–accuracy trade-off or ignores a signal’s often non-stationary character. Here we introduce an open-source algorithm to calculate the fast continuous wavelet transform (fCWT). T
Image Signal Processing (ISP) is the processs of converting an image into digital form by performing operations like noise reduction, auto exposure, autofocus, auto white balance, HDR correction, and image sharpening with a Specialized type of media processor.

In the latter paper the intervals between collapses have 123 150 Queueing Systems (2021) 99:121–159 a general distribution, and the random reduction factor at collapses has a minus-log phase-type distribution, i.e., minus its natural logarithm has a phase-type distribution. This corresponds ...
Airflow-induced noise prediction and reduction is one of the priorities for both the energy and aviation industries. This review paper provides valuable insights into flow-induced noise computation, prediction, and optimization methods with state-of-the-art efforts in passive noise reduction on airfoil...
Since the Q-function is a decreasing function, an increase in the average transmit power PT or a reduction in the noise power N0/2 or a decrease in the bit rate Rb or a combination of these three changes can reduce the minimum bit error rate....
Consequently, network inference algorithms should strongly benefit from an a priori reduction in the number of alternative routes. In the following we present an unbiased network inference algorithm that eliminates alternative routes with low signal-to-noise ratio as a preprocessing step. Inference of ...
