Various structural discontinuities, which form a discrete fracture network, play a significant role in the failure conditions and stability of the rock masses around underground excavations. Several continuum numerical methods have been used to study the stability of underground excavations in jointed rock masses but only few of them can take into account the influence of the pre-existing natur...

Archaeological excavations in the Areni-1 cave complex in southeastern Armenia revealed installations and artifacts dating to around 4000 cal. BCE that are strongly indicative of wine production. Chemical evidence for this hypothesis is presented here using a new method to detect the anthocyanin malvidin that gives grapes and pomegranates their red color. Using solid phase extraction (SPE) and ...

Modern excavations yielded a distribution of the house areas in the ancient Egyptian city Akhetaten, which was populated for a short period during the 14th century B.C. Assuming that the house area has a power law dependence of the wealth of its inhabitants allows us to make a comparison of the wealth distributions in ancient and modern societies.

INtrODUctION The science of Archaeology has been in existence for a long time and the way an archaeological excavation is conducted hasn't changed much. However, the way archaeological data is recorded has changed dramatically by the progress of technology and the widespread use of computers. Nowadays, almost any archaeological excavation uses databases to record not only the objects which have...

The use of supporting fluids to stabilize excavations is a common technique adopted in the construction industry. Rapid detection incipient collapse for deep and timely decision making are crucial ensure safety during construction. This paper explores hybrid framework forecasting fluid-supported circular by combining physics-based data-driven modeling. Finite-element limit analysis first used d...
