Group B

Let H3 be the upper half-space model of the three-dimensional hyperbolic space. For certain cocompact Fuchsian subgroups Γ of an extended Bianchi group Bd, the extremality of the axis of hyperbolic F ∈ Γ in H3 with respect to Γ implies its extremality with respect to Bd. This reduction is used to obtain sharp lower bounds for the Hurwitz constants and lower bounds for the highest limit points in the Markov spectra of Bd for some d < 1000. In particular, such bounds are found for all non-Euclidean class one imaginary quadratic fields. The Hurwitz constants for the imaginary quadratic fields with discriminants -120 and -132 are given. The second minima are also indicated for these fields.

Engineering Practices

Choosing an accurate soil model is the key point in calculating the foundation settlement. The commonly used models in engineering practices are the Winkler’s model, elastic half space model and finite compressible layer model. Among these models, the finite compressible layer model is widely used in the designing of raft foundation. As the finite compressible layer model can not reflect the nature of the in situ soil and the nonlinear settlement, in this paper we try to modify the elastic modulus E by the secant modulus in order to improve the soil model of finite compressible layer.
