Optimal Surface Coating
The short-term clinical failures of cementless stems, such as proximal bone resorption and thigh pain, have limited their acceptance despite the potential long-term benefits of biological fixation for younger and more active patients. The clinical problems are believed to be related to failure at the bone-stem interface. By optimizing the design of the prosthesis to prevent or minimize failure ...
متن کاملNeural Networks Analysis of Airfield Pavement Heavy Weight Deflectometer Data
The Heavy Weight Deflectometer (HWD) test is one of the most widely used tests for assessing the structural integrity of airport pavements in a non-destructive manner. The elastic moduli of the individual pavement layers predicted from the HWD deflection measurements through inverse engineering analysis are effective indicators of pavement layer condition. The primary objective of this study wa...
متن کاملSmooth particle hydrodynamics simulation of surface coating
The simulation of plane impinging jets using the Lagrangian technique of smooth particle hydrodynamics is presented. In Section 1 the impingement of a plane jet onto a stationary surface is considered for Reynolds numbers 800, 4000, 8000 and Froude number 4. For each case, the height of the associated streams is measured and compared with both experimental and theoretical results. The agreement...
متن کاملThe Surface Coating of Car Bodies
Step 2 Phosphating The metal is treated with phosphoric acid, leading to the following two reactions occuring in the zinc-rich surface of the steel: 2H3PO4 + 3Zn → 3H2 + Zn3(PO4)2 2H3PO4 + Fe + 2Zn → 3H2 + FeZn2(PO4)2 This gives a mixture of zinc phosphates. The electrocoat paint binds better to these zinc phosphates than to the steel alone, and the zinc phosphates corrode much slower than the ...
متن کاملAirfield Pavement Deicing with Conductive Concrete Overlay
Conductive concrete is a cementitious admixture containing a certain volumetric ratio of electrically conductive materials to attain high and stable electrical conductivity. Due to its electrical resistance, a thin overlay of conductive concrete can generate enough heat to prevent ice formation when energized by AC power. Under a research sponsored by Nebraska Department of Roads, Yehia and Tua...
