Multigrid methods for improving the variational data assimilation in numerical weather prediction [PDF]

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2014
Two conditions are needed to solve numerical weather prediction models: initial condition and boundary condition. The initial condition has an especially important bearing on the model performance.

A numerical model for durotaxis [PDF]

open access: yesJournal of Theoretical Biology, 2011
Cell migration is a phenomenon that is involved in several physiological processes. In the absence of external guiding factors it shares analogies with Brownian motion. The presence of biochemical or biophysical cues, on the other hand, can influence cell migration transforming it in a biased random movement.

On the Hughes model and numerical aspects [PDF]

open access: yes2016 IEEE 55th Conference on Decision and Control (CDC), 2016
We study a crowd model proposed by R. Hughes and we describe a numerical approach to solve it. The Hughes model comprises a Fokker-Planck equation coupled with an eikonal equation with Dirichlet or Neumann data. First, we establish a priori estimates for the solutions. Second, we study radial solutions and identify a shock formation mechanism.

Improving the Gaussianity of radar reflectivity departures between observations and simulations using symmetric rain rates [PDF]

open access: yesAtmospheric Measurement Techniques
Given that the Gaussianity of the observation error distribution is the fundamental principle of some data assimilation and machine learning algorithms, the error structure of radar reflectivity has become increasingly important with the development of ...

Numerical Predictive Combustion Model of Hydrogen Enriched Natural Gas [PDF]

open access: yesMATEC Web of Conferences, 2022
Hydrogen was established as one of the main pillars of energy stability in the Europe Union. One of the ways how to achieve this goal is natural gas enriched with hydrogen.

Development of a new and modification of existing elastic clips for rails fastening

open access: yesGrađevinar, 2022
One of the problems of railway fastening systems (fastening system) that occurs due to the development of railways is the damage of the elastic clips, which leads to the loss of structural integrity between the rail and the base.
