Due to low counts in an (111)In single photon emission computed tomography (SPECT) scan, a large part of the head was missing in the reconstructed images on Philips Extended Brilliance Workspace (EBW) and IntelliSpace Portal (ISP) workstations. This problem occurred for the ordered subsets expectation maximization (OSEM) algorithm with and without resolution recovery (Astonish), but not for fil...

This thesis introduces a novel technique for noise robust speech recognition by first describing a speech signal through a set of broad speech units, and then conducting a more detailed analysis from these broad classes. These classes are formed by grouping together parts of the acoustic signal that have similar temporal and spectral characteristics, and therefore have much less variability tha...

In this paper, we have successfully extended our previous work of convex optimization methods to MMIE-based discriminative training for large vocabulary continuous speech recognition. Specifically, we have re-formulated the MMIE training into a second order cone programming (SOCP) program using some convex relaxation techniques that we have previously proposed. Moreover, the entire SOCP formula...

In this paper we derive the well known EBW reestimation formulae for Gaussian mixture models using the recently proposed reverse Jensen inequality. In addition to the simplicity of the derivation, it leads to closed form expressions for the D of each Gaussian in the mixture. Using some approximations, it is shown that the expressions can be reduced to the popular formula of [8] with a Gaussian ...

The high-β operating regime of spherical tokamaks (ST), such as in NSTX and MAST, make them attractive fusion devices. For access to such high β regimes, it is necessary to heat and to drive currents in ST plasmas. While such plasmas are overdense to conventional electron cyclotron waves, electron Bernstein waves (EBW) offer an attractive means toward this purpose. The applications of EBWs in S...

Results Primary outcome was hospital days, following initial admission, at 12-month follow-up. Secondary outcomes were total hospital days to 12-months and full remission (EBW>95% and global Eating Disorder Examination score within 1 SD of published means). There was no significant difference between groups in hospital days used following initial admission. There were significantly more total h...

：A new distribution called the exponentiated Burr XII Weibull(EBW) distributions is proposed and presented. This contains several known such as log-logistic Weibull, Rayleigh, exponential, Lomax Exponential, Rayleigh exponential special cases. A comprehensive investigation of properties this generalized including series expansion probability density function cumulative function, hazard reverse ...

Although neural networks (NNs) have been applied for trac and congestion control in ATM networks, many implementations only consider a single service class with identical trac characteristics and requirements. In addition, the most commonly used NN is the multi-layer perceptron (MLP) networks which are known to converge slowly. We present a multi-service connection admission control (CAC) sch...
