This paper describes a statistical spectral parameter emphasis technique for HMM-based speech synthesis using mel-scaled line spectral pair (mel-LSP). Spectral parameter emphasis is effective for compensating over-smoothed spectra in HMM-based speech synthesis. However, there is no conventional technique that satisfies such requirements as automatic tuning for different speakers and realtime sy...

Monopulse radarsare one of the most accurate tracking radars used to guide various platforms. Detection and tracking of surface targets with these radars are performed in order to point strike targets. Sea clutter presents challenges for detecting floated targets and in addition to affecting detection height, it can cause errors in monopulse angle finding. In this paper, the airborne monopulse ...

The failure probability of engineering structures such as aircraft, bridges, dams, nuclear structures, and ships, as well as microelectronic components and medical implants, must be kept extremely low, typically <10(-6). The safety factors needed to ensure it have so far been assessed empirically. For perfectly ductile and perfectly brittle structures, the empirical approach is sufficient becau...

Markov modulated self-similar processes are proposed to model MPEG video sequences that can capture the LRD (Long Range Dependency) characteristics of video ACF (Auto-Correlation Function). The basic idea is to decompose an MPEG compressed video sequence into three parts according to different motion/content complexity such that each part can individually be described by a self-similar process....

Ever since the 1980s there is a sustained interest in size effect, as one of most pronounced consequences fracture mechanics. In present study, investigation effect focused on estimation Weibull cumulative distribution function (CDF) critical value J-integral (Jc) transition temperature region under constraint small statistical sample size. Specifically, Jc experimental data correspond to C(T) ...

Due to the influence of atmospheric environment and pointing errors, performance free space optical communication is greatly limited. In this paper, we propose a parallel multi-hop hybrid (FSO)/radio frequency (RF) system improve performance. The FSO sub-link RF are modeled by Gamma–Gamma turbulence with errors Nakagami-m distributions, respectively. Based on selective combination scheme, proba...

Multiple input multiple output (MIMO) approach in fiber optical communication has emerged as an effective proposition to address the ever increasing demand for information exchange. In ergodic case, channels, associated with modes or cores both fiber, is modeled by Jacobi ensemble of random matrices. A key quantity assessing performance MIMO systems mutual (MI). We focus here on case arbitrary ...

This paper traces the development/evolution of three of our recently proposed MPEG coded video traffic models, that can capture the statistical properties of MPEG video data. The basic ideas behind these models are to decompose an MPEG compressed video sequence into several parts according to motion/scene complexity or data structure. Each part is described by a self-similar process. These diff...

Two variational formulas for the power of the binary hypothesis testing problem are derived. The first is given as the Legendre transform of a certain function and the second, induced from the first, is given in terms of the Cumulative Distribution Function (CDF) of the log-likelihood ratio. One application of the first formula is an upper bound on the power of the binary hypothesis testing pro...
