In this paper, we prove that the direction of cepstrum vectors strongly depends on vocal tract length and that this dependency is represented as rotation in a cepstrum space. In speech recognition studies, vocal tract length normalization (VTLN) techniques are widely used to cancel ageand gender-difference. In VTLN, a frequency warping is often carried out and it can be modeled as a linear tran...

The performances of the current face recognition systems suffer heavily from the variations in lighting. To deal with this problem, this paper presents an illumination normalization approach by relighting face images to a canonical illumination based on the harmonic images model. Benefiting from the observations that human faces share similar shape, and the albedos of the face surfaces are quas...

We develop a quasi-normal mode theory (QNMT) to calculate system's scattering $S$ matrix, simultaneously satisfying both energy conservation and reciprocity even for small truncated set of resonances. It is practical reduced-order (few-parameter) model based on the resonant frequencies constant mode-to-port coupling coefficients, easily computed from an eigensolver without need QNM normalizatio...

A (complex) Enriques surface is a projective smooth connected algebraic surface Y over C with H(Y,OY ) = H (Y,OY ) = (0), (Ω 2 Y ) ⊗ 2 ≃ OY but Ω 2 Y 6≃ OY ([CF]). In this note we give a short proof of the fact that the coarse moduli space of complex Enriques surfaces is quasi-affine. This was first shown by Borcherds [B] using the denominator function of a generalized Kac-Moody superalgebra (t...

For a quasidifferentiable function f defined on R 2 , it is proved, in the sense of Demyanov and Rubinov, that the following assertion [∂f (x),∂f (x)]∈Df (x) (∂f (x) + ∂f (x)), [∂f (x),∂f (x)]∈Df (x) (∂f (x) − ∂f (x)) ∈ Df (x) in this paper, where Df (x) denotes the set of all quasidifferentials of f at x. It is shown that this way can be viewed as an approach to determining or choosing a repre...

This paper investigates the issues of combination and normalization of interval-valued belief structures within the framework of Dempster–Shafer theory (DST) of evidence. Existing approaches are reviewed, examined and critically analysed. They either ignore the normalization or separate it from the combination process, leading to irrational or suboptimal interval-valued belief structures. A new...

modern world revolutions have created some instruments known as ‎quasi-negotiable instruments which are different from negotiable ones, ‎despite having some similarities to them. commercial custom recognizes ‎them as quasi-negotiable instruments. the principle is that we don’t ‎need new legal regime for this new category because they are right in ‎personam when they are created and rights in re...

Image covariance features, enabled with efficient fusion of several different types of image features without any weighting or normalization, have low dimensions. The covariance-based trackers are robust and versatile with a modest computational cost. This paper investigates an object tracking algorithm using a sequential quasi-Monte Carlo (SQMC) filter combined with covariance features. The co...

RNA sequencing (RNA-seq) is widely used to profile transcriptional activity in biological systems. Here we present an analysis pipeline for differential expression analysis of RNA-seq experiments using the Rsubread and edgeR software packages. The basic pipeline includes read alignment and counting, filtering and normalization, modelling of biological variability and hypothesis testing. For hyp...

We ®rst review quasi Monte Carlo (QMC) integration for approximating integrals, which we believe is a useful tool often overlooked by statistics researchers. We then present a manuallyadaptive extension of QMC for approximating marginal densities when the joint density is known up to a normalization constant. Randomization and a batch-wise approach involving …0; s†-sequences are the cornerstone...
