Deformation Analysis of Large Diameter Monopiles of Offshore Wind Turbines under Scour

Applied Sciences, 2020
The displacement of monopile supporting offshore wind turbines needs to be strictly controlled, and the influence of local scour can not be ignored. Using p–y curves to simulate the pile–soil interaction and the finite difference method to calculate ...

P Y Curves of Laterally Loaded Piles Near Earth Slopes

International Journal of Engineering and Advanced Technology, 2020
Design of piles under lateral loads using numerical analysis is a time-consuming process, requiring competent geotechnical engineers who can accurately model the soil profile and construction sequence. Therefore, most engineers have resorted to the p-y method that is a less time-consuming process in both the modeling and running time.

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

Research on optimization of p-y spring model applied in bucket foundation-soil interaction along horizontal direction

Yantu gongcheng xuebao
As a new type of marine foundation, bucket foundation has been increasingly applied in the offshore wind turbine engineering. Its stable service performance is closely related to the interaction between bucket foundation and marine soil.

A Numerical Analysis on Lateral Resistance of Pile–Bucket Foundation for Offshore Wind Turbines

Applied Sciences, 2022
The large-diameter single pile has been widely used in marine wind turbine foundations. In order to improve its lateral bearing capacity, the suction bucket foundation (BF) can be used as a reinforcement method, which surrounds the periphery of the ...

Small-displacement behavior of offshore wind power monopiles subjected to static lateral loading

Yantu gongcheng xuebao
The centrifuge tests and numerical simulations are carried out to explore the small-displacement behavior of 9 m-diameter offshore wind power large-scale monopiles with various embedment depths. The results show that as the embedment depth increases, the

Sato--Tate, cyclicity, and divisibility statistics on average for elliptic curves of small height

, 2007
We obtain asymptotic formulae for the number of primes $p\le x$ for which the reduction modulo $p$ of the elliptic curve $$ \E_{a,b} : Y^2 = X^3 + aX + b $$ satisfies certain ``natural'' properties, on average over integers $a$ and $b$ with $|a|\le A ...

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about
