This chapter presents ViSta-PrnCmp, the module for Principal Components Analysis (PCA) in ViSta. This procedure is capable of analyzing numerical variables so they can be represented on a lower dimensionality space. The visualization for ViSta-PrnCmp includes a scatterplot-matrix of component scores; a bi-dimensional biplot; a tri-dimensional (spin-plot) version of the biplot; a box-diamond-dot...

Segment selection in the L&h Realspeak laboratory TTS system

The L&H RealSpeak Laboratory TTS (RSLab) system is a corpus based speech synthesis system comprising components that deal with linguistic processing, prosody prediction, segment selection, concatenation and modification. In this paper we focus on the segment selection process. During segment selection, the units in a large database of speech are scored with a cost according to their prosodic/ph...

Squareness in the special L-value and special L-values of twists

Let N be a prime and let A be a quotient of J0(N) over Q associated to a newform such that the special L-value of A (at s = 1) is non-zero. Suppose that the algebraic part of the special L-value of A is divisible by an odd prime q such that q does not divide the numerator of N−1 12 . Then the Birch and Swinnerton-Dyer conjecture predicts that the q-adic valuations of the algebraic part of the s...

Special Values of Abelian L - Functions at S = 0

In [12], Stark formulated his far-reaching refined conjecture on the first derivative of abelian (imprimitive) L–functions of order of vanishing r = 1 at s = 0. In [10], Rubin extended Stark’s refined conjecture to describe the r-th derivative of abelian (imprimitive) L-functions of order of vanishing r at s = 0, for arbitrary values r. However, in both Stark’s and Rubin’s setups, the order of ...
