A usual way of ASR accuracy evaluation is calculation of Word Error Rate (WER) and Sentence Error Rate (SER). The misrecognitions that contribute to WER are classified into three categories: deletions, insertions and substitutions. The paper presents a study about a contribution of intrinsic speech variabilities to the each of the error category. Decision tree (DT) analysis is used. Five DT sty...

We consider a general class of birth-and-death processes with state space {0,1,2,3,…} which describes the size population going eventually to extinction probability one. obtain complete spectrum generator process killed at 0 in large limit, that is, we scale by parameter K, and take limit K→+∞. assume differential equation dx/dt=b(x)−d(x) describing infinite (in any finite-time interval) has re...

Phytoseiid mites are important for biological control of some pest species including phytophagous and small insects. The species, Phytoseius corniger Wainstein is one the most abundant predatory mite in fruit orchards urban green spaces Razavi Khorasan province, Iran. Biological parameters this feeding on two-spotted spider Tetranychus urticae Koch was studied first time under laboratory condit...

The development and life history parameters of Neoseiulus agrestis feeding on the storage mite, Thyreophagus sp., were studied at three different temperatures 20, 25, 30 °C. results show that juvenile oviposition period as well reproductive potential this predatory mite are significantly affected by temperature. times immature expectancy adults ranged from 11.36 to 6.06 days 58.71 38.65 days, r...

PURPOSE Prostate-specific antigen (PSA) doubling-time (PSA-DT) is an important indicator of progression and survival in men with prostate cancer. Three major limitations regarding PSA-DT determination may lead to inconsistent results: the variety of mathematical methods currently applied, the non-standardized handling of input variables and the potential lack of accuracy due to PSA variability....

PURPOSE A short posttreatment prostate specific antigen (PSA)-doubling time (DT) following radical prostatectomy or radiation therapy was evaluated as a surrogate end point for prostate cancer specific mortality (PCSM). MATERIALS AND METHODS Baseline, treatment and followup information was compiled on a cohort of 8,669 patients with prostate cancer treated with surgery (5,918) or radiation (2...

background bronchopulmonary dysplasia (bpd) is one of the most common serious squeal of preterm infants. it involves approximately one quarter of infants with birth weight less than 1500 grams and 30% of less than 1000 grams. vitamin a has been shown to reduce bpd rate. we compared efficacy of low and high doses of vitamin a for prevention of bpd in very low birth weight preterm infants. materi...

BACKGROUND Dynamic population models, or models with changing vital rates, are only beginning to receive serious attention from mathematical demographers. Despite considerable progress, there is still no general analytical solution for the size or composition of a population generated by an arbitrary sequence of vital rates. OBJECTIVE The paper introduces a new approach, Intrinsic Linkage, that...
