A number of inventories of the Blanchet concern are extant, providing valuable information about the technique of French harpsichord building.
OPRAH uses a simulated annealing algorithm and information about extant native vegetation, land use and rehabilitation costs, to find solutions to non-linear landscape-scale problems.
However that may be, from Proclus' extant works and the information about his lost works it emerges that he was a productive writer indeed.
Extant Egyptian documents provide valuable information about Palestine in the period of the Egyptian 12th dynasty (1938 1756 bce) and argue for significant Egyptian interest and influence in Palestine at this time.
Because fossils have a rather different information content than do extant organisms (e.g., less information about soft anatomy and almost invariably no access to DNA characters), various conventions have been devised to accommodate fossils in classifications (see Smith 1994).
Stem pinniped fossils were particularly important for the comparative analyses (disparity analyses were extant-only) because they provide information about the ancestral morphology of the group.
Because there are few extant pieces from the early periods, information about early furniture is gleaned from literary descriptions, engravings on mirrors, clay images, and graphic representations.
Students showed significant improvements in three skill-based items: inferring ancestral traits when provided with information about the traits of extant taxa (Q.6), mapping character state changes while constructing trees (Q.7c), and aligning extant taxa at branch tips while constructing trees (Q.7d; Table 3 and Figure 3).
From the numerous references to such machines in extant tragedies or comedies and vase paintings, information about its design and operation is available, and efforts to reconstruct such mechanisms have been reported in the literature.
For example, reasonable elastic property estimates of cortical bone from fossil hominid skulls should be possible once adequate information about such properties in extant great apes is added to our current data from humans, macaques, and baboons.
