Researchers at the University of Freiburg, the University of Pittsburgh and the University of Akron have now discovered that this adhesion hysteresis is caused by thesurface roughnessof the adherent soft materials. Through a combination of experimental observations and simulations, the team demonstrated t...
Gaussian surface elevation fields (6m×6m) were generated for a range of slopes and roughnesses (sill σ and range R of the variogram). A full factorial of 6 slopes (0–15%), 6 values of R (50–400mm) and 6 values of σ (2–40mm) was considered, and the RSCf calculated for ...
摘要: Numerical simulations are performed for the stick-slip motion in the Burridge-Knopoff model of one block. Calculated amplitude increases with the driving velocity. We argue that this effect can be a criterion to distinguish between the stick-slip and pure slip oscillations....
aThe ratio of the average squared differences of the interclass means to the sum of the Intraclass variances are calculated and this quantity is denoted as. interclass手段的平均被摆正的区别的比与Intraclass变化的总和被计算,并且这个数量表示。[translate] ...
What is the Gravimetric Method for Paint Thickness Measurement? By measuring the mass and area of the coating, thickness can be determined. The simplest method is to weigh the part before and after coating. Once the mass and area have been determined, the thickness is calculated using the foll...
These are determined by the first and second derivatives of the surface topography and can be evaluated through a point-by-point analysis of the data. Equation 3: Equation 4: Using the equivalent radius, the corrected elastic modulus,Ec, is calculated from the measured modulus,Er, and...
How is power pump calculated? Pump Power calculation Formula: Pump Power P(kW)= q(m3/hr)x ρ(kg/m3)x g(m2/s)x h(m)x p(Pa)/ 3600000. The same way pump power in horsepower formula can be written as, Pump Power P(HP)= q(m3/hr)x ρ(kg/m3)x g(m2/s)x h(m)x p(Pa)...
and were calculated using the following: where q is specific humidity, g is the acceleration due to gravity, V is the horizontal wind, Pt is the air pressure at the top of the atmosphere, and Ps is the surface air pressure. The cumulative components were calculated from 0000 UTC on Nove...
For each panel, urban porosity and average building side length are calculated from the building footprint data. Additionally, the DEM of each panel is analyzed to find the maximum slope and direction. We subsequently calculate the effective chord length in the direction of maximum slope in each...
Surprisingly, the technique to fix a crack in a boat’s hull is pretty much the same as methods used to repair a hole with epoxy. Step 1: Clean and flatten the aluminum surface Bring the damaged hole back to its original shape by doing the similar technique to fix a boat hull. Also,...
