Abstract: The direct boundary integral equation due to Burton and Miller (1971) is used for the solution of the Helmholtz equation in the exterior domain. The formulation is complex, involving four ...

Abstract: The largest salt-gradient solar pond in the U. S. occupies an area of 2020 m2 and was installed for only $35/m2 . The pond has a storage layer of 1.6 m consisting of 18 percent sodium ...

Abstract: In this paper we study an efficient boundary element method for the determination of the acoustic field around arbitrary-shaped finite structures immersed in an infinite homogeneous acoustic ...

Abstract: Despite the many advantages of using lasers for welding ceramics (alumina in particular), cracks induced by the resulting and severe thermal stresses are often detrimental to weld quality and ...

Abstract: In 1971, dioxin contaminated wastes were dumped on a dirt farmroad in rural Missouri. Subsequent migration of the soil led to the contamination of the shoulders of an adjacent state highway. Kriging, a geostatistical ...

Abstract: An instrument package developed for measuring six-level, dry-bulb and wet-bulb temperature profiles above forests is described. Germanium diodes, incorporated into a constant current circuit, were used as temperature ...

Abstract: The abrasiveness of hard carbon-containing thin films such as diamond-like carbon (DLC) and boron carbide (nominally B4C) towards steel is considered here. First, a remarkably simple experimentally ...

Abstract: In diseases such as hydrocephalus, the cerebral ventricles enlarge. The treatment options for these patients are presently based on pressure, which has limited capabilities. We present the design ...

Abstract: Steel coupling beams have emerged as a viable alternative to conventionally and diagonally reinforced concrete coupling beams because of their superior energy-dissipation characteristics, smaller member depth, and ease of ...
