The first design of a morphing wing (Re-MOW) is based on two-stage rhombus-type DAMs. In the first stage, a retraction-type electrothermal actuator (ReACT) consisting of a diamond-shaped displacement amplification structure (DAS) and an actuating bar that is thermally expanded by thin-film ...
He then spent most of another day programming and testing in the game, and after multiple refinements, he finally completed this popular online science video.The Agriculture Irrigation System was built around 256 BC and still 3.___ function) more than 2,000 years later. Unlike modern dams, ...
Other events and issues such as natural disasters, war, the construction of dams, and poverty in developing countries also contribute to the destruction of tropical rainforests.What Can You Do to Help Save the Tropical Rainforest Preserving tropical rainforests involves more than just deciding not ...
[1] We examined channel response following the removal of low-head dams on two low-gradient, fine- to coarse-grained rivers in southern Wisconsin. Following removal, channels eroded large quantities of fine sediment, resulting in deposition 3–5 km downstream. At one site (Baraboo River), ups...
Two-noded springs can be connected to any two nodes of the finite element mesh using theAdd Two-Noded Springsoption. The location for both ends of the spring can be specified. If one end of a two-node spring was assigned to a composite liner or structural interface, it will be assign...

2021). Thus, in warm periods, riverine fishes can potentially move into these cool-water refugia to maintain their body temperatures at physiologically optimum levels, providing their ability to access them is not inhibited by anthropogenically constructed barriers, such as weirs and dams (Grill et ...
In the United States, there are approximately 84,000 dams including approximately 14,000 dams that are classified as high hazard. Approximately 50% of high... DR Judi,SJ Burian,TN Mcpherson - 《Journal of Water Resources Planning & Management》 被引量: 4发表: 2015年 Numerical Simulation of ...
His research currently focuses on hydraulic structural health diagnosis, mainly including detecting technology and equipment for concrete microcracks, telemetry and equipment for concrete microcracks, detecting and visualizing reinforcement technology and equipment for deep-buried diseases in high dams, and ...
They have been strongly modified by the construction of dams, by wastewater treatment plant inputs and by hydro-electrical facilities. Both rivers have previously been studied mainly for the most common heavy metals (e.g. zinc, lead, cadmium, copper) and organic pollutants (e.g. perfluoroalkyl...
