Karl Rawer’s interest and encouragement regarding new approaches to ionospheric modeling

New Approaches in 3D Geomechanical Earth Modeling

In this paper two new approaches for building 3D Geomechanical Earth Model (GEM) were introduced. The first method is a hybrid of geostatistical estimators, Bayesian inference, Markov chain and Monte Carlo, which is called Model Based Geostatistics (MBG). It has utilized to achieve more accurate geomechanical model and condition the model and parameters of variogram. The second approach is the ...

Ionospheric Propagation Effects on GNSS Signals and New Correction Approaches

New approaches in Medium Scale Travelling Ionospheric Disturbances modelling

The Medium Scale Travelling Ionospheric Disturbances (MSTIDs) are the most frequent wave signatures in the ionosphere, with amplitudes up to several TECUs, periods from several hundreds to one-two thousands of seconds, and propagation velocities from 50 to +300 m/s, mainly equator-eastward in winter/fall seasons, and westward in summer/spring seasons (M. Hernandez-Pajares et al., Radio Science,...

New approaches to operational risk modeling

Estimation of economic capital of a financial institution requires modeling of operational losses of the business units of the organization. Operational losses of the financial institution are usually represented as an aggregate sum of the losses incurred by the operational events of the business units. Simulation of these events requires the introduction of a co-dependence structure for a more...

New Approaches to Modeling Elastic Media

In this chapter we suggest new models for the study of deformations of elastic media through the minimization of distortion functionals. This provides a “holistic” approach to this problem and a potential mathematical underpinning of a number of phenomena which are actually observed. The functionals we study are conformally invariant and give measures of the local anisotropic deformation of the...
