Abstract: Greenhouse gas (GHG) emissions are widely acknowledged to be responsible for much of the global warming in the past century. Since the burning of fossil-based fuels is an important source of GHGs, the policies on GHG ...

Abstract: The global optimal solution for the underactuated attitude maneuver plays a significant role in the fields of spacecraft, robotics, and mechanics. This paper investigated the global optimal underactuated attitude maneuver ...

Abstract: Infiltration tests were conducted in the laboratory to study water movement during infiltration in compacted clay and to determine the suction head at the wetting front as defined in the Green-Ampt infiltration equation. ...

Abstract: The problem of sliding surface tractions on a porous biphasic layer with viscous interstitial fluid is solved, which can serve as the basis for solving problems of elastohydrodynamic lubrication ...

Abstract: An asymptotic procedure is presented to evaluate the tracer trajectory in a two-stream turbulent pipe mixing unit with an oblique branch. The proposed mixing jet trajectory estimate near the ...

Abstract: A database is described that contains laboratory measurements of hydraulic conductivity and associated soil properties that were extracted from construction reports for compacted soil liners. The database contains measurements ...

Abstract: Flow field plays an important role in proton exchange membrane fuel cell (PEMFC) performance. Excellent flow field configuration promotes the transport of reactant gases in the membrane electrode assembly (MEA), effectively ...

Abstract: Iron tailings (IT) are by-products of iron ore mining, which have the characteristics of high stockpile and low cost. Recycling IT as alternatives for high-quality quartz sand (QS) in ultrahigh-performance mortar (UHPM) ...

Abstract: The coning problems for vertical wells and the ridging problems for horizontal wells are very difficult to solve by conventional methods during oil production from reservoirs with bottom water ...
