This paper evaluates the performance of R-22, R-290, R-290/600a (70/30), and R-32/152a (50/50) for application in a water-to-water residential heat pump for
We review some of our recent studies on elastic constants, internal friction, and related properties of two-phase materials. The occluded-phase geometry
Expect is a tool for automating interactive programs. Expect is controlled by writing Tcl scripts, traditionally a manual process. This paper describes
The International Standard STEP (ISO 10303) is intended to facilitate the exchange of data between CAD systems. The first release of the standard, which
A new method of describing designs by combining the paradigms of shape algebras and predicate logic representations is presented. Representing shapes and
The National Institute of Standards and Technology is developing a dimensional pitch standard covering the range 1 micrometers to 10 mm, intended for the
Manufacturing features and their interactions have become areas of research scrutiny in recent years. It is widely accepted that intelligent reasoning about
