and the term y(n)∙ x/|x|2 in brackets can be ignored, unless, as will be shown below, the sum of the source amplitudes is zero. However, the dependence on y(n) in the complex exponential cannot be ignored because it can dominate the result if some phase cancelation occurs in the...
Although we cannot completely rule out the existence of periodic daily movements outside the EARs detection range, analysis of the acoustic behaviour of dolphins indicates a diel cycle in the use of distinct vocalizations, which may explain observed day-night differences in dolphin detections. All ...
We did not believe that direct visualization of the glottis was necessary to rule out laryngeal pathology if the child and parent had no voice complaints. Furthermore, we believed that using the validated PVRQOL survey and the CAPE-V form would help ensure that we were in fact testing normal...
Host function and device kernel for matrix GMM method In fact, the logSum for the mix probability is a highly parallel implementation by the general parallel case, however, we must consider the variable Gaussian mix num. So we use the loop operation which loses part of effective. IV. ...
As a rule of thumb, the width dimension or length dimension of the area should be 1/6 of the wavelength of sound for the highest frequency of interest. What can Q be used for? Utilizing a device called aQsourceacoustic exciter, it is possible to take some interesting measurements by gener...
Disorders limited to the auditory nerve include neuropathies and intracanalicular vestibular schwannoma (also called acoustic neuroma). When the disease is limited to the auditory nerve without involvement of the cochlea, the cochlear microphonic, the summating potentials of the electrocochleogram and ...
19.The computer-readable storage device of claim 15, wherein the respective concatenation cost comprises a weighted sum of subcosts across phones. 20.The computer-readable storage device of claim 15, wherein the concatenation cost database is generated using statistical techniques which predict which...
the pollen and nectar sources in a given area, there is a maximum number of beehives that can be placed in one apiary. Too many beehives placed in one apiary result in competition for scarce resources. A good rule of thumb is to have no more than 25-40 beehives in a permanent apiary....
