For compact and efficient actuation, miniature hydraulic system has overwhelming superiority in power to weight ratio.However, it always involves nonlinear interferences like variable hose volume or oil bulk modulus, which greatly restricts control performance for the actuation.In this paper, a miniature hydraulic volume-controlled actuation system
The United States Department of Agriculture Forest Service (Forest Service) manages 154 national forests and 20 grasslands in 44 states and Puerto Rico.National Forest Land and Resource Management Plans (forest plans) form the basis for land and resource management of national forests in the United States.For more than a decade the Forest Service h
This work utilizes cement kiln dust in fly ash and blast furnace slag-based geopolymer.Geopolymer cement was produced using different compositions of ground, granulated blast furnace slag with fly ash and cement bypass flue dust.Crystalline sodium metasilicate pentahydrate was used as an activator at 10, 15 and 20% Accessories (by weight) of the ge
