This paper presents a novel training algorithm for Hidden Markov Model (HMM)-based speech synthesis. One of the biggest issues causing significant quality degradation in synthetic speech is the over-smoothing effect often observed in generated speech parameter trajectories. Recently, we have found that a Modulation Spectrum (MS) of the generated speech parameters is sensitively correlated with ...

The aim of this study is to address a new feature extraction method in the area of the heart arrhythmia classification based on a metric with simple mathematical calculation called Curve-Length Method (CLM). In the presented method, curve length of the under study excerpted segment of signal is considered as an informative feature in which the effect of important geometric parameters of the ori...

Deep and frequent GPS signal fading due to strong ionospheric scintillation is major concern for aircraft navigation in the equatorial region during solar maximum periods. Deep signal fading can break a receiver’s carrier tracking lock on a satellite channel and the satellite cannot be used for position solution until a receiver reacquires the lost channel. Frequent signal fading also causes fr...

BACKGROUND A type III error arises from a two-sided test, when one side is erroneously favoured although the true effect actually resides on the other side. The relevance of this grave error in decision-making is studied for epidemiological maps. RESULTS Theoretical considerations confirm that a type III error may be large for regions with small numbers of expected cases even when no spatial ...

In this paper we study a bivariate smoothing approach for estimating multiple functional parameters for functional data with a two-dimensional domain. We present a penalized regression framework for smoothing with the purpose to: (a) facilitate the estimation of the smooth overall bivariate mean function of two-dimensional functional data, (b) enable the estimation of the functional effect of a...

Tax avoidance and income smoothing are important issues that impact the company's operations. The complexity between these two phenomena affects firm value, which is often influenced by family ownership, influences how manufacturing companies avoid tax smoothing. This study aims to examine effect of on with ownership as a moderating variable. Hypothesis testing was carried out using multiple re...

T value of information sharing and how it could address the bullwhip effect have been the subject of studies in the literature. Most of these studies used different forms of demand models, assuming that no order smoothing was used by the retailer and that the supplier has full knowledge of the retailer’s demand model and order policy. In this paper, we contribute to the literature by starting w...

We are interested in this article in investigating the smoothing effect properties of the solutions of the Schrödinger equation. Since the work by Craig, Kapeller and Strausss [13], Kato [16], Constantin and Saut [12] establishing the smoothing property, many works have dealt with the understanding of this effect. In particular the work by Doi [14] and Burq [5, 6] shows that it is closely relat...
