Abstract: It is shown that both sticking (hydraulic lock) and lateral vibrations of pistons can be caused by hydrodynamic forces. Corrective methods are discussed.

Abstract: Three grid-connected monocrystalline silicon photovoltaic arrays have been instrumented with research-grade sensors on the Gaithersburg, MD campus of the National Institute of Standards and Technology (NIST). These arrays ...

Abstract: Commercial-scale solar photovoltaic (PV) arrays were designed, constructed, and are now operational on the Gaithersburg, Maryland campus of the National Institute of Standards and Technology (NIST). A design–bid–build ...

Abstract: During the early expansion of western America a group of Mormon pioneers came to the Great Salt Lake valley in covered wagons, arriving in July of 1847. Here they began to build a city. In the center of the city they ...

Abstract: The slow manifold of an inviscid five-mode model introduced by Lorenz is investigated. When the influence of the gravity modes on the Rossby modes is neglected, the analytical solution given by Lorenz and Krishnamurthy is ...

Abstract: This study develops a macroscopic model of mass transport in electroporated biological tissue in order to predict the cellular drug uptake. The change in the macroscopic mass transport coefficient is related to the increase ...

Abstract: Andrews and Hoskins used semigeostrophic theory to argue that the energy spectrum of a front should decay like the ?8/3 power of the wavenumber. They note, however, that their inviscid analysis is restricted to the very ...
