Circular plates with radially varying thickness, stiffness, and density are widely used for the structural optimization in engineering. The axisymmetric flexural free vibration of such plates, governed by coupled diff...
Although the relationship between pay level and pay satisfaction has been verified as one of the most robust relationships in the literature of pay satisfaction, scholars have not yet reached an agreement regarding it...
Let M be a compact Riemann surface, h(x) a positive smooth function on M, and Ф(x) a smooth function on M which satisfies that ∫MeФdVg = 1. In this paper, we consider the functionalJ(u)=1/2∫M|△u|2eФdVg+...
The formaidehyde-free finishing agent 4,5-di-hydroxy-1,3-dimethy1-2-imidazolidinone(DMeDHEU)was prepared by the reaction of 1,3-dimethylurea and glyoxal.The reaction rate and equilib-rium conversion in relation to pH ...
