adaptation of the lord of the rings is considered by many to be among the greatest, most successful and at the same time most popular of the above mentioned trend so far. it is my intention to look at the success and popularity of this epic fantasy in the light of the 9/11 attacks and the war on terror context of g. w. bush’s aura. in so doing i aim at bringing into the light the determining fa...
After Northridge (1994) and Kobe (1995) earthquakes, several studies have been conducted to improve the seismic performance of steel structures. In this investigation, new steel moment-resisting connections (FSFN) developed by the authors, were studied by the non-linear numerical analysis. These connections were single-sided beam-to-column assemblies that are representative of exterior beam-to-...
In order to see the occurrence of magnetic reconnection in the solar chromosphere, we investigate the behavior of non-linear perturbations on the magneto hydro dynamic (MHD) equations. Numericalstudy of the resistive tearing instability in a current sheet is presented by considering the MHD framework.To do this, the four field model is applied. It is shown based on the simulation that the non-l...
To complete traditional time- and frequency-domain analyses, new methods derived from non-linear systems analysis have recently been developed for time series studies. A panel of the most widely used methods of heart rate analysis is given with computations on mouse data, before and after a single atropine injection.
Endurance time (ET) method is a relatively new performance-based earthquake method for structural evaluation and design. In this method, the structure is subjected to a gradually intensifying accelorogram(s) and its performance is assessed based on the maximum time duration that it can meet the specified performance objectives. Using moment-resisting and braced frames which are rehabilitated by...
In this paper, we assess whether using non-linear dimension reduction techniques pays off for forecasting inflation in real-time. Several recent methods from the machine learning literature are adopted to map a large dimensional dataset into lower-dimensional set of latent factors. We model relationship between and factors constant time-varying parameter (TVP) regressions with shrinkage priors....
Relationship between age and measures of balance, strength and gait: linear and non-linear analyses.
An age-related decline in balance, gait and lower-extremity muscle strength measures may lead to increased risk of falls and fractures. Previous studies have reported a possible non-linear age-related decline in these measures, but the choice of methodological approach has limited its interpretation. Healthy community-dwelling women (n=212) 21-82 years of age were evaluated for strength [Nichol...
