Crustal thickness in Vrancea area-Romania from S to P converted waves
Crustal thickness (CT) in Vrancea region (Romania) and adjacent area is investigated using 1294 S to P converted waves from the Moho discontinuity. A total of 269 local earthquakes in the depth range 99.8 to 171.1 km and recorded by 76 permanent and 46 temporary stations of the Romanian Seismological Network are used. Time difference between the converted wave and the direct P phase is corrected to a first order for epicentral distance and for the

In this article we shall give a generalization of Cobb–Douglas, Constant Elasticity of Substitution (CES), Lu–Fletcher, Liu–Hildebrand, Variable Elasticity of Substitution (VES) and Kadiyala production functions. We compute the principal indicators such as the marginal products, the marginal rate of substitution, the elasticities of factors and the elasticity of substitution. Finally,we formulate three theorems of characterization for the functions
