We analyse a model of the phosphorus cycle in the ocean given by Slomp and Van Cappellen (Biogeosciences 4:155-171, 2007. 10.5194/bg-4-155-2007). This model contains four distinct oceanic boxes and includes relevant parts of the water, carb...
Adaptive multi-parameter regularization approach to construct the distribution function of relaxation times [0.03%]
自适应多参数正则化构造弛豫时间分布函数的方法

Mark Žic et al.
Determination of the distribution function of relaxation times (DFRT) is an approach that gives us more detailed insight into system processes, which are not observable by simple electrochemical impedance spectroscopy (EIS) measurements. DF...
A cut finite element method for elliptic bulk problems with embedded surfaces [0.03%]
带有嵌入曲面的椭圆主体问题的切割有限元方法

Erik Burman et al.
We propose an unfitted finite element method for flow in fractured porous media. The coupling across the fracture uses a Nitsche type mortaring, allowing for an accurate representation of the jump in the normal component of the gradient of ...
Simulation of settlement and bearing capacity of shallow foundations with soft particle code (SPARC) and FE [0.03%]

In this study we investigate the development of shear zones due to the settlement of shallow foundations and their load-settlement behavior. Firstly, a well-documented experiment of shallow penetration into sand is used for the validation o...
The inverse scattering problem for orthotropic media in polarization-sensitive optical coherence tomography [0.03%]
各向异性介质在偏振敏感光学相干断层扫描成像中的逆散射问题研究

Peter Elbau
In this paper we provide for a first time, to our knowledge, a mathematical model for imaging an anisotropic, orthotropic medium with polarization-sensitive optical coherence tomography. The imaging problem is formulated as an inverse scatt...
Romberg extrapolation for Euler summation-based cubature on regular regions [0.03%]
基于Euler求和的正则区域立方方法的Romberg加速算法
W Freeden,C Gerhards
W Freeden
Romberg extrapolation is a long-known method to improve the convergence rate of the trapezoidal rule on intervals. For simple regions such as the cube [Formula: see text] it is directly transferable to cubature in q dimensions. In this pape...

The aim of this paper is to numerically investigate the development, thickness and orientation of shear bands, in biaxial test with two approaches towards solving problems of continuum mechanics, namely the meshless "Soft PARticle" method a...
