This article aims to examine methods of optimizing GMM-based voice conversion systems performance in which GMM method is introduced as the basic method for improvement of voice conversion systems performance. In the current methods, due to using a single conversion function to convert all speech units and subsequent spectral smoothing arising from statistical averaging, we will observe quality ...

in the present study, the effects of calcium doping on the performance of the co-precipitated cu-mgo catalysts prepared with different calcium loadings in the selective hydrogenation of furfuraldehyde were investigated. the results proved that the addition of this promoter had a remarkable impact on the catalytic performance. the conversion of furfuraldehyde enhanced up to 83% and the furfuryl ...

Voice conversion (VC) is an area of speech processing that deals with the conversion of the perceived speaker identity. In other words, the speech signal uttered by a first speaker, the source speaker, is modified to sound as if it was spoken by a second speaker, referred to as the target speaker. The most obvious use case for voice conversion is text-to-speech (TTS) synthesis where VC techniqu...

Rotation among opioids to minimize side effects and improve analgesia is a common clinical strategy in pain and palliative care. Methadone is frequently prescribed during opioid rotation, either by mouth or intravenously (IV) with patient-controlled analgesia (PCA) at home. However, there is a lack of consensus on rotation strategies from other opioids to methadone, as well as on conversion rat...

Recent advances in 3D have increased the importance of stereoscopic content creation and processing. Therefore, converting existing 2D contents into 3D contents is very important for growing 3D market. The most difficult task in 2D-to-3D conversion is estimating depth map from a single-view image. Thus, in this paper, we propose a novel algorithm to estimate the map by simulating haze as a glob...

The diagnosis of psychogenic nonepileptic seizures has become easier with the assimilation of studies on the clinical categorization of seizure-like events (1), video EEG monitoring (2), measurement of serum prolactin (3), the selective use of neuropsychological tests (4), and various other diagnostic methods. Much less information is available to the clinician on what to do next. How should th...

In the present study, the effects of calcium doping on the performance of the co-precipitated Cu-MgO catalysts prepared with different calcium loadings in the selective hydrogenation of furfuraldehyde were investigated. The results proved that the addition of this promoter had a remarkable impact on the catalytic performance. The conversion of furfuraldehyde enhanced up to 83% and the furfuryl ...

conclusions previous abdominal surgery, including previous colonic surgery, confers no added risk of conversion to an open operation, morbidity or mortality for patients undergoing laparoscopic colorectal surgery. the operative time however is longer (30 minutes) for patients with previous colonic surgery. results out of 718 patients 476 had no previous abdominal surgery (group a), whilst 190 p...
