Also, many of their calculations depend heavily on the mass estimates for the pterosaurs.
Good correspondence is found in the added mass estimates of the two methods.
Further confirmation of these peaks was provided by the accurate mass estimates provide by TOF-MS (Figure 4).
In this section, we first state the local well-posedness of system (1.2) and then give the mass estimates.
Mass estimates of the S4 reactor design that meets both the thermal and the reactivity requirements are provided.
This increases the uncertainty of the black hole mass estimates using the virial theorem for AGNs with broader lines.
When the mass estimates don't match up with the observed size of the cluster, the difference is assumed to be due to dark matter (ScienceNOW, 15 April 2002).
In most cases, those mass estimates chimed closely with how bright the clusters appeared as expected from observing the Milky Way's clusters.
The authors assumed a mass of 250 kilograms for the giant Quetzalcoatlus when in reality, says Unwin, such mass estimates vary widely.
The 2dF group aims to measure the speeds of 250,000 galaxies by the end of 2001, and the mass estimates will improve with more data, Dalton notes.
In general, they are somewhat complex to compute and may have deficiencies such as negative mass estimates at given points (Prentice et al. 2004).
