In this paper, we propose a statistical method of evaluating the pronunciation proficiency of Japanese words. We analyze statistically the utterances to note a combination that has a high correlation between a Japanese teacher’s score and certain acoustic features. We found that the syllable recognition rates (accuracy) was the best measure of pronunciation proficiency. The effective measure wh...

In this study the effects of temperature on anaerobic co-digestion of saw dust with cattle dung is investigated. It also simulates the biogas production from saw dust with cattle dung at various temperatures. Results showed that high temperature could improve the anaerobic digestion and hence increase the biogas production rates. The operating temperatures used in this study were 35°C, 45°C, an...

BACKGROUND The pressure-recording analytical method is a new semi-invasive method for cardiac output measurement (PRAM). There are no studies comparing this technique with femoral artery thermodilution (FATD) in an infant animal model. METHODS A prospective study was performed using 25 immature Maryland pigs weighing 9.5 kg. Fifty-eight simultaneous measurements of cardiac index (CI) were mad...

BACKGROUND Radiographs are used to monitor thoracic kyphosis in individuals with certain pathologies (e.g. osteoporosis), exposing patients to potentially harmful radiation. Thus, other measures for monitoring the progression of thoracic kyphosis are desirable. The gravity-dependent inclinometer has been shown to be reliable but its validity as a measure of thoracic kyphosis has not been invest...

OBJECTIVE To study the correlation between 18F-FDG uptake and cell proliferation in cancer patients by meta-analysis of published articles. METHODS We searched PubMed (MEDLINE included), EMBASE, and Cochrane Database of Systematic Review, and selected research articles on the relationship between 18F-FDG uptake and Ki-67 expression (published between August 1, 1994-August 1, 2014), according ...

We improve an algorithm originally due to Chudnovsky and Chudnovsky for computing one selected term in a linear recurrent sequence with polynomial coefficients. Using baby-steps / giant-steps techniques, the nth term in such a sequence can be computed in time proportional to √ n, instead of n for a naive approach. As an intermediate result, we give a fast algorithm for computing the values take...

The solutions to a change problem form restricted partitions. For one particular change problem, we look at the sequence representing the parity of these restricted partition values. It appears that the period of this sequence has not been studied. Through recurrences involving binomial coefficients, we find that the sequence has a period of 200.

Le but de cette note est essentiellement de présenter des conjectures ainsi que des indications sur les raisons qui nous ont portées à énoncer ces conjectures. Les conjectures portent sur la forme explicite d’équations de récurrence que semble satisfaire la suite th(n), des nombres de tableaux de Young de hauteur bornée par h, ainsi que la suite t (2) h (n), des nombres de paires de tels tablea...
