The energy parameter has been widely used as an extension to the basic features of mel-frequency cepstral coefficients (MFCCs) to improve the recognition accuracy in speech recognition. In this paper, a simple and effective approach for energy normalization for silence (non-speech) portions in an utterance is proposed. This approach, named as silence energy normalization (SEN), uses the high-pa...

Shapiro and Wilk (1965) proposed a highly intuitive goodness-offit test of normality with nuisance location and scale parameters. The test has received a considerable attention in the literature; its asymptotic null distribution is covered by the results of de Wet and Wenter (1973), and was recently studied by Sen (2002). We extend the Shapiro-Wilk test to the situation with nuisance regression...

BACKGROUND Short bowel syndrome (SBS) can lead to intestinal failure and require total or supplemental parenteral nutrition (TPN or PN, respectively). Glucagon-like peptide 2 (GLP-2) is a nutrient-dependent, proglucagon-derived gut hormone that stimulates intestinal adaptation. OBJECTIVE Our objective was to determine whether supplemental enteral nutrients (SEN) modulate the intestinotrophic ...

INTRODUCTION Clostridium difficile infection (CDI) remains a diagnostic challenge for clinicians. More recently, loop-mediated isothermal amplification (LAMP) has become readily available for the diagnosis of CDI, and many studies have investigated the usefulness of LAMP for rapid and accurate diagnosis of CDI. However, the overall diagnostic accuracy of LAMP for CDI remains unclear. In this me...

The use of computational steering for smog prediction is described. This application is representative for many underlying issues found in steering high performance applications: high computing times, large data sets, and many diierent input parameters. After a short description of the smog prediction model, its visualization and steering are described. The amount of computation needed to solve...

We test perturbatively a recent scheme for implementing chiral fermions on the lattice, proposed by Kaplan and modified by Narayanan and Neuberger, using as our testing ground the chiral Schwinger model. The scheme is found to reproduce the desired form of the effective action, whose real part is gauge invariant and whose imaginary part gives the correct anomaly in the continuum limit, once tec...

In Mexico, students with special educational needs (SEN) can study in regular schools or without the support of education professionals, schools. The purpose this research is to identify academic performance SEN who attend general public Mexican schools, and support, from urban rural areas states Querétaro, San Luis Potosí Sonora. These were nominated as successful by authorities each entity. D...

Computational steering is a technique that combines simulation and visualization. The user is continuously provided with visual feedback about the state of the simulation, and can change parameters on the y. Designers can vary parameters to optimize their product, users can detect errors in the input early, researchers can do qualitative sensitivity analyses easily. The implementation of comput...

We present a method for the deenition of multiple views in 3D interfaces for computational steering. The method uses the concept of a point-based parametrizable camera object. This concept enables a user to create and conngure multiple views on his custom 3D interface in an intuitive graphical manner. Each view can be coupled to objects present in the interface, parametrized to (simulation) dat...
