Abstract The alkali–silica reaction (ASR) can cause expansion, cracking, and degradation of the mechanical properties affected concrete. Concerns about safety ASR-damaged reinforced concrete structures have driven demand for studying effects ASR on residual load capacity deteriorated structure. Conventionally, field testing methods are used to assess ASR-affected structures. In this study, a no...

Automatic speech recognition (ASR) model adaptation is important to many real-life ASR applications due to the variability of speech. The differences of speaker, bandwidth, context, channel and et al. between speech databases of initial ASR models and application data can be major obstacles to the effectiveness of ASR models. ASR models, therefore, need to be adapted to the application environm...

The University at Buffalo (UB) team participated in the SpokenQuery&Doc task at the NTCIR-12, working on the Spoken Content Retrieval (SCR) subtask. We investigated the use of multiple ASR hypotheses (words) and subword units (syllables) for improving retrieval effectiveness. We also compared the retrieval effectiveness based on texts generated by two automatic speech recognition (ASR) engines,...

We evaluated the performance characteristics of three real-time reverse transcription-PCR test systems for detection and quantification of hepatitis C virus (HCV) and performed a direct comparison of the systems on the same clinical specimens. Commercial HCV panels (genotype 1b) were used to evaluate linear range, sensitivity, and precision. The Roche COBAS TaqMan HCV test for research use only...

In this paper we describe some of our recent investigations into ASR and SMT coupling issues from an ASR perspective. Our study was motivated by several areas: Firstly, to understand how standard ASR tuning procedures effect the SMT performance and whether it is safe to perform this tuning in isolation. Secondly, to investigate how vocabulary and segmentation mismatches between the ASR and SMT ...

Despite several decades of research, automatic speech recognition (ASR) lacks the performance achieved by human listeners. One of the major challenges in ASR is to cope with the immense variability of spoken language, which can be categorized into extrinsic sources (e.g., additive noise) and intrinsic factors (such as speaking rate, style, effort, dialect, and accent). What can we learn from th...

The strength of the acoustic startle response (ASR) to short bursts of broadband noise or tone pips (4, 8 and 16 kHz) and the prepulse inhibition (PPI) of the ASR elicited by prepulse tones (4, 8 and 16 kHz) were measured in parvalbumin-deficient (PV-/-) mice and in age-matched PV+/+ mice as controls. Hearing thresholds as determined from recordings of auditory brainstem responses were found to...

BACKGROUND Female cancer, especially breast and gynecologic cancers are considered multistage disease, highly influenced by risk and protective factors and/or screening preventive modalities. Consequences of all these factors result in the trend of change over time. METHODS In this comparative study, based on data of national cancer registry of Iran 2004 published by Iranian Ministry of Healt...

In this paper, we propose a mathematical study to simulate the dynamics of alkali–silica reaction (ASR) by using Caputo fractional derivative. We solve non-linear fractional-order system containing six differential equations understand ASR. For proving existence unique solution, use some recent novel properties Mittag–Leffler function along with fixed point theory. The stability proposed is als...
