Artificial neural networks were designed to model the unique architecture of the human brain, and are used to solve complex problems that are otherwise hard to solve using traditional algorithmic techniques.
Neural networks are used in character recognition, speech recognition, and can be applied to NP-complete problems including the traveling salesman problem.
Instead, estimates are made based on the tree's size and presumed growth rate.
The second table includes trees with these estimated ages.
In addition, tree ages are derived from a variety of sources, including documented "tree-ring" count core samples, and from estimates.
For these reasons, this article presents three lists of "oldest trees," each using varying criteria.

The MWCNTs synthesized here were characterized by a transmission electron microscope, a Raman spectrophotometer and a wide angle X-ray diffractometer.
For some old trees, so much of the centre is missing that their age cannot be directly determined.
Together these findings suggest that surface tension may be used to determine how nanoparticle structure affects neurotoxicity and protein conformational changes.
Carbon nanotubes (CNTs) present several unique chemical, thermal, optical, mechanical, electrical and structural properties that make them ideal candidate in biomedical application for the treatment of wide range of disorders.
One of the main disadvantages of CNTs is the lack of solubility and the low biocompatibility in the physiological media.
CNTs have been functionalized with the different hydrophilic moieties to overcome these problems.
