Beyond the standard IAU framework
نویسنده
چکیده
We discuss three conceivable scenarios of extension and/or modification of the IAU relativistic resolutions on time scales and spatial coordinates beyond the Standard IAU Framework. These scenarios include: (1) the formalism of the monopole and dipole moment transformations of the metric tensor replacing the scale transformations of time and space coordinates; (2) implementing the parameterized post-Newtonian formalism with two PPN parameters β and γ; (3) embedding the post-Newtonian barycentric reference system to the Friedman-RobertsonWalker cosmological model.

متن کاملForensic Voice Comparison Using Chinese /iau/
An acoustic-phonetic forensic-voice-comparison system extracted information from the formant trajectories of tokens of Standard Chinese /iau/. When this information was added to a generic automatic forensic-voice-comparison system, which did not itself exploit acoustic-phonetic information, there was a substantial improvement in system validity but a decline in system reliability.
متن کاملMass of the Galaxy Inferred from Outer Rotation Curve
Using an outer rotation curve of the Galaxy, we explore the galactic constants and the mass of the Galaxy. We show that Θ0 of 200 km s −1 is more favorable than the IAU standard value of 220 km s, and also show that if Θ0 is smaller than 207 km s −1 the rotation curve beyond 2R0 is declining in Keplerian fashion. In the case of Θ0= 200 km s −1 and R0= 7.6 kpc, the total mass and the extent of t...
متن کاملOrganizational Learning and Knowledge Spillover in Innovation Networks: Agent-Based Approach (Extending SKIN Framework)
In knowledge-based economy, knowledge has a public good and non-rivalry nature. Firms build their own knowledge stock not only by means of internal R&D and collaboration with partners, but also by means of previously spilled over knowledge of other firms and public research laboratories (such as universities). Firms based on their absorptive capacity, and level of intra-industry and extra-indus...
متن کاملAn Investigation of Automatic Phonetic-Unit Selection for Forensic Voice Comparison
A hybrid Hidden Markov Model (HMM) Gaussian Mixture Model (GMM) system was proposed to automatically select tokens of /iau/, /ai/, /ei/, /m/ and /n/ in a database of recordings of Standard-Chinese speech collected under studio-clean, mobile-landline degraded and mismatched recording conditions. The FVC systems constructed were all MFCC GMM-UBM systems, but based on different portions of the rec...
