Finite Element Simulation of NiTi Umbrella-Shaped Implant Used on Femoral Head under Different Loadings

Bioengineering, 2017
In this study, an umbrella-shaped device that is used for osteonecrosis treatment is simulated. The femoral head is subjected to various complex loadings as a result of a person’s daily movements. Implant devices used in the body are made of shape memory

Application of agent-based modelling for selecting configuration of vertical slot fishway

Građevinar, 2021
Physical and 3D numerical hydrodynamic flow models and an agent-based model are developed with the principal objective of analysing fish behaviour in two vertical slot fishway configurations.

Prediction of Beach Sand Particle Size Based on Artificial Intelligence Technology Using Low-Altitude Drone Images

Journal of Marine Science and Engineering
Coastal erosion is caused by various factors, such as harbor development along coastal areas and climate change. Erosion has been accelerated recently due to sea level rises, increased occurrence of swells, and higher-power storm waves.

A Neural Model of How the Brain Represents and Compares Multi-Digit Numbers: Spatial and Categorical Processes [PDF]

, 2001
Both animals and humans are capable of representing and comparing numerical quantities, but only humans seem to have evolved multi-digit place-value number systems.

Enriching the Symphony of Gravitational Waves from Binary Black Holes by Tuning Higher Harmonics

, 2018
For the first time, we construct an inspiral-merger-ringdown waveform model within the effective-one-body formalism for spinning, nonprecessing binary black holes that includes gravitational modes beyond the dominant $(\ell,|m|) = (2,2)$ mode ...

Impact of the horizontal resolution of GEOS-Chem on land‒ocean and tropic‒extratropic partitioning and seasonal cycle in CO2 inversion

Environmental Research Letters
Credible regional carbon budget estimates from atmospheric CO _2 measurements rely on the accuracy of atmospheric transport models (ATMs). However, the atmospheric transport in ATMs is usually simplified and spatiotemporally averaged, leading to ...

Closure of two dimensional turbulence: the role of pressure gradients

, 2002
Inverse energy cascade regime of two dimensional turbulence is investigated by means of high resolution numerical simulations. Numerical computations of conditional averages of transverse pressure gradient increments are found to be compatible with a ...

Pseudospectral versus finite-differences schemes in the numerical integration of stochastic models of surface growth

, 2007
We present a comparison between finite differences schemes and a pseudospectral method applied to the numerical integration of stochastic partial differential equations that model surface growth. We have studied, in 1+1 dimensions, the Kardar, Parisi and

Numerical study of a non-equilibrium interface model

, 1996
We have carried out extensive computer simulations of one-dimensional models related to the low noise (solid-on-solid) non-equilibrium interface of a two dimensional anchored Toom model with unbiased and biased noise.
