Accurate shortterm analysis of the fundamental frequency and the harmonicstonoise ratio of a sampled sound
 IFA Proceedings 17
, 1993
"... We present a straightforward and robust algorithm for periodicity detection, working in the lag (autocorrelation) domain. When it is tested for periodic signals and for signals with additive noise or jitter, it proves to be several orders of magnitude more accurate than the methods commonly used for ..."

the position of the maximum of the autocorrelation function of the sound, while the degree of periodicity (the harmonicstonoise ratio) of the sound can be found from the relative height of this maximum. However, sampling and windowing cause problems in accurately determining the position and height
HEIGHT
"... A Conditional Random Field is a mathematical model for sequences that is similar in many ways to a Hidden Markov Model, but is discriminative rather than generative in nature. Here we explore the application of the CRF model to ASR processing by building a system that performs firstpass phonetic re ..."

"... We report on a continuing study of multigap parallel plate avalanche chambers; primarily as photoelectron detectors forme with Cerenkov ring imaging counters. By suitable control of the fields in Successive gaps and by introducing screens to reduce photon feedback to the cathode the gain may be incr ..."

be increased considerably. We have obtained gains in excess of 6 X 10 ' for photoelectrons with a good pulse height spectrum and expect to increase this further. We discuss the use of resistive anodes to give avalanche positions in two dimensions by charge division.
Continuity and discontinuity of behavioral inhibition and exuberance: Psychophysiological and behavioral influences across the first four years of life.
 Child Development,
, 2001
"... Abstract: Fourmonthold infants were screened (N = 433) for temperamental patterns thought to predict behavioral inhibition, including motor reactivity and the expression of negative affect. Those selected (N = 153) were assessed at multiple age points across the first 4 years of life for behavior ..."

from all channels of the EEG record prior to subsequent analysis. The rereferenced, artifactscored EEG data were submitted to a discrete Fourier transform analysis that utilized a Hanning window with 50% overlap. The result of this analysis was to produce power in picowatt ohms (or microvolts squared
The Digital Prolate Spheroidal Window
"... The optimal window, the time limited sequence whose energy is most concentrated in a finite frequency interval is related to a particular discrete prolate spheroidal sequence. The optimal window is actually a family of windows with many degrees of freedom. The Kaiser window is an approximation to th ..."

Asymmetries in the Processing of Vowel Height
"... a Purpose: Speech perception can be described as the transformation of continuous acoustic information into discrete memory representations. Therefore, research on neural representations of speech sounds is particularly important for a better understanding of this transformation. Speech perception ..."

models make specific assumptions regarding the representation of mid vowels (e.g., [e]) that are articulated with a neutral position in regard to height. One hypothesis is that their representation is less specific than the representation of vowels with a more specific position (e.g., [ae]). Method: In a
TREE INCLUSIONS IN WINDOWS AND SLICES
"... Abstract. P is an embedded subtree of T if P can be obtained by deleting some nodes from T: if a node v is deleted, all edges adjacent to v are also deleted, and outgoing edges are replaced by edges going from the parent of v (if it exists) to the children of v. Deciding whether P is an embedded sub ..."

subtree of T is known to be NPcomplete. Given two trees (a target T and a pattern P) and a natural number w, we address two problems: 1. counting the number of windows of T having height exactly w and containing pattern P as an embedded subtree, and 2. counting the number of slices of T having height
A simulationbased review of the ubiquitous windowheadheight to daylit zone depth ruleofthumb

"... This paper reviews the validity of the ubiquitous daylighting rule of thumb (DRT) that relates windowheadheight to the depth of the daylit area adjacent to a facade. Different versions of the rule taken from prominent daylighting design guides and norms are presented. A formal link is established ..."
