Glottalization of coda /t, p/ is a common process in American English. This study uses acoustic measures to determine when coda glottalization occurs in the conversational speech of the Buckeye Corpus. Vowels preceding coda /t, p/ tokens for 40 speakers were analyzed using H1*–H2*, an acoustic correlate of glottal constriction. Results indicate that coda glottalization is more common before a s...

In earthquake source estimation, coda-derived source methods provide more stable source parameters than methods using direct waves due to the inherent averaging nature of coda waves (Mayeda and Walter, 1996; Mayeda et al., 2007). Unlike conventional direct-phase regional measurements (e.g., Pg or Lg), which take peak amplitude at the specific arrival time, the coda amplitude measurement through...

seismic waves when crossing the earth in heterogeneous and anisotropic environments, having interaction. recognizing the impact of these factors on the seismograms help us to find out more information about interior of the earth. coda waves are the main reason for the random heterogeneities in earth. local earthquakes in the northeast region of iran with epicentral distance less than 200 km is ...

An advanced distributed file system like Coda is an integral part of today’s mobile environment. This is due to the limitations of having large storage capacities on small mobile devices, finite battery life and the ubiquitous nature of wireless networking today. However, systems such as Coda do not perform optimally on low bandwidth connections such as low-speed error prone wireless links and ...

[1] The influence of density variation on scattering is investigated in terms of attenuation, coda level, and apparent frequency shift. The influence of density variations is to producemore scattered energy than for velocity perturbations alone with a consequently higher coda level. The temporal decay of the coda is reduced, so that high perturbations in density are associated with a long durat...

In this study, statistical analysis is used to investigate nasal coda loss in spoken Standard Chinese. In order to find out the factors that influence nasal coda loss, we take into account the segmental and supra-segmental features and their interactions. We find out that articulation manner, post nasal coda boundary and tone influenced the nasal coda loss significantly, the interaction between...

This paper provides an overview of the CODA framework for modelling and refinement of componentbased embedded systems. CODA is an extension of Event-B and UML-B and is supported by a plugin for the Rodin toolset. CODA augments Event-B with constructs for component-based modelling including components, communications ports, port connectors, timed communications and timing triggers. Component beh...

Coda waves are sensitive to changes in the subsurface because the strong scattering that generates these waves causes coda waves to repeatedly sample a limited region of space. Coda wave interferometry is a technique that exploits this sensitivity to estimate weak changes in the medium from a comparison of the coda waves before and after the perturbation. Here I present the general theory of co...
