We carried out several numerical experiments to analyze how different boundary conditions affect the ability detect small pipeline leaks. Our method is based on determining soil temperature gradient above a buried district heating channel. The equivalent thermal conductivity of wet insulation (λeq) value 0.5 W/(m·K) was used mimic water leakage. To evaluate heat loss through channel cross secti...

OBJECTIVES The objective of this program was to exploit low frequency structural acoustic clues which might exist in the scattered acoustic fields from buried and near-buried mines for long range, rapid mine classification and identification. Once these structural acoustic mechanisms and clues were established in the free--field scattering from these mines, the goal was to establish the basic e...

The first know description of buried penis was by Keyes in 1919. Buried penis was described as the “absence of the penis exists when the penis, lacking its proper sheath of skin, lies buried beneath the integument of the abdomen, thigh or scrotum (Keyes, 1919).” Classically, the entity of buried penis has been primarily discussed in the pediatric population (Boemers & De Jong, 1995, Crawford, 1...

According to the Department of Defense, over 10 million acres of land in the US need to be cleared of buried unexploded ordnance (UXO). Worldwide, UXO injures thousands each year. Cleanup costs are prohibitively expensive due to the difficulties in discriminating buried UXO from other inert non-UXO objects. Government agencies are actively searching for improved sensor methodologies to detect a...

Buried horizons and lenses in riparian soil profiles harbor large amounts of carbon relative to the surrounding soil horizons. Because these buried soil horizons, as well as deep surface horizons, frequently lie beneath the water table, their impact on nitrogen transport across the terrestrial–aquatic interface depends upon their frequency and spatial distribution, and upon the lability of asso...

Inverted strip buried heterostructure lasers have been fabricated. These lasers have threshold currents and quantum efficiencies that are comparable to those of conventional buried heterostructure lasers. The optical mode is confined by a weakly guiding strip loaded waveguide which makes possible operation in the fundamental transverse mode for larger stripe widths than is possible for conventi...
