An Eulerian-Lagrangian method for open channel flows

A discrete vector potential method for unsteady 3-D Navier-Stokes equations.

Pointwise and uniform approximation of the Hilbert transform

The Hilbert transform of a function g, H(g) is an important tool in many mathematical fields. Expecially its numerical evaluation is often useful in some procedures for searcing solutions of the singular integral equations. In this context an approximation of (HV^alpha,beta,f;t), |t|1, where f is a…

Implementation of a model for the horizontal gradients in the ESA retrieval algorithm for MIPAS

Neglecting the horizontal variability of the atmosphere in the forward model for the simulation of limb emission radiances causes a systematic error in MIPAS retrieved profiles. The horizontal gradient model will be introduced into the Optimized Retrieval Model (ORM) v8, which will be used for the…

Preventing the drop in security investments for non-competitive cyber-insurance market

The rapid development of cyber insurance market brings forward the question about the effect of cyber insurance on cyber security. Some researchers believe that the effect should be positive as organisations will be forced to maintain a high level of security in order to pay lower premiums. On the…

Tor Marketplaces Exploratory Data Analysis: The Drugs Case

The anonymous marketplaces ecosystem represents a new channel for black market/goods and services, offering a huge variety of illegal items. For many darknet marketplaces, the overall sales incidence is not (yet) comparable with the correspondent physical market; however, since it represents a…

A one-dimensional vertical ecosystem model for lake dynamics

We present a modified version of an existing lake ecosystem model, describing a trophic chain generated by nutrients, phytoplankton and zooplankton (NPZ model). The NPZ model takes into account the vertical dynamics of the biomasses of the main species. We tailor the model to specific ecosystems by…
