Abstract: Via its impact on surface fluxes, subseasonal variability in soil moisture has the potential to feed back on regional atmospheric circulations, and thereby rainfall. An understanding of this feedback mechanism in the climate ...

Abstract: The elastic distortion of the inner ring of an experimental 3 × 106 DN roller bearing is investigated analytically. The geometry of this bearing is unusually complex and for this reason ...

Abstract: Computer-aided design (CAD) systems have become parametric, basing shape design on constraints and design feature operations. We review the development of constraint-based parametric CAD, explaining ...

Abstract: Geometric computation software tends to be fragile and fails occasionally. This robustness problem is rooted in the difficulty of making unambiguous decisions about incidence and nonincidence, ...

Abstract: Early constraint solvers used propagation techniques that were inadequate for solving simultaneous constraint problems. Simultaneous problems, also called variational problems, require solving systems ...

Abstract: Temperature data derived from Nimbus 4 SIRS radiance measurements have been used in four-dimensional assimilation experiments with a simple two-level primitive equation model. Data are inserted into a running forecast on ...

Abstract: Vertical soundings of temperature and moisture derived from the GOES VISSR Atmospheric Sounder (VAS) measurements have been produced operationally since summer 1987 at the VAS Data Utilization Center (VDUC). The algorithm ...

Abstract: This article provides recommendations on how to evaluate existing passive anchorage systems for Tainter gates. A review of various types of passive anchorage systems is provided, along with a detailed example problem. The ...

Abstract: Supercavitating baffle blocks, with their unique geometry, have been shown to be highly effective in reducing cavitation damage to stilling basins’ floors and to the baffle blocks themselves. However, this unique geometry, ...
