P-y curves on model piles: Uncertainty identification
, 2010 The aim of determining the P-y reaction curves. The instrumented pile allows the bending moment profiles to be obtained. The uncertainty on the moment measurement is first quantified. The displacements are determined from a polynomial function fitted on the moment data and calculated by double-integrating the moment.

Families of noncongruent numbers [PDF]
, 2002 Let E_k denote the elliptic curve defined by y^2 = x(x^2 - k^2). We consider the curves with k = pl, p = l = 1 mod 8 primes, and show that the density of rank-0 curves among them is at least 1/2 by explicitly constructing nontrivial elements in the 2 ...

Estimation of Genetic Parameters for Peak Yield, Yield and Persistency Traits in Murciano-Granadina Goats Using Multi-Traits Models [PDF]
, 2019 This paper studies parameters of a lactation curve such as peak yield (PY) and persistency (P), which do not conform to the usual selection criteria in the Murciano-Granadina (MG) breed, but are considered to be an alternative to benefit animal welfare ...

p-y curves for lateral bearing behavior of strength composite piles in soft clay
Yantu gongcheng xuebao, 2020 The strength composite (SC) pile is a novel type of pile technology which combines high-strength concrete piles and deep cement-mxing (DCM) columns. To attain a theoretical approach for the lateral bearing capacity of SC piles in soft clay, the cement ...

Numerical derivation of CPT-based p–y curves for piles in sand [PDF]
Géotechnique, 2014 The formulations for the lateral load–displacement (p–y) springs conventionally used for the analysis of laterally loaded piles have been based largely on the back-analysis of the performance of small-scale instrumented piles subjected to lateral load.

Shallow-layer p-y curves for single micropile in sands
Yantu gongcheng xuebao, 2018 Micropiles are increasingly used in seismic design or retrofitting for pile foundations. This study aims to investigate the validity of the widely used p-y relationships proposed by the American Petroleum Institute (API) and the ‘m method'; in the ...

Integral points on generic fibers
, 2008 Let P(x,y) be a rational polynomial and k in Q be a generic value. If the curve (P(x,y)=k) is irreducible and admits an infinite number of points whose coordinates are integers then there exist algebraic automorphisms that send P(x,y) to the polynomial x
