this paper presents the numerical analysis of seismic soil-pile-superstructure interaction in soft clay using free-field soil analysis and beam on winkler foundation approach. this model is developed to compute the nonlinear response of single piles under seismic loads, based on one-dimensional finite element formulation. the parameters of the proposed model are calibrated by fitting the experi...

 Fitting a suitable covariance function for the correlation structure of spatial-temporal data requires de-trending the data. In this article, some potential models for spatial-temporal trend are presented. Eventually the best model will be announced for de-trending tropospheric ozone concentration data for the city of Tehran (Capital city of Iran). By using the selected trend model, some ...

Active contour models based on local region fitting energy can segment images with intensity inhomogeneity effectively, but their segmentation results are easy to error if the initial contour is inappropriate. In this paper, we present a simple and universal method of improving the robustness of initial contour for these local fitting-based models. The core idea of proposed method is exchanging...

Miniaturized liquid sensors are essential devices in online process or condition monitoring. In case of viscosity and density sensing, microacoustic sensors such as quartz crystal resonators or SAW devices have proved particularly useful. However, these devices basically measure a thin-film viscosity, which is often not comparable to the macroscopic parameters probed by conventional viscometers...

In 1987-2001 unemployment and inßation have the opposite inßuences on the popularities of Finnish and Swedish leftist and rightist parties. The popularities of the Finnish right-wing (left-wing) parties decrease (increase) when unemployment and inßation increase but in Sweden the opposite happens although the countries experience simultaneously an economic crisis. Fitting a threshold model in t...

We introduce a generic and efficient method for 2D and 3D shape estimation via density Þelds. Our method models shape as a density map and uses the notion of density to Þt a model to a rapidly computed occupancy map of the foreground object. We show how to utilize hierarchical (pyramid-like) object segmentation data to regularize a hierarchical model Þtting. With primary focus on estimating 3D ...

An ice-free Arctic summer would have pronounced impacts on global climate, coastal habitats, national security, and the shipping industry. Rapid and accelerated Arctic sea ice loss has placed the reality of an ice-free Arctic summer even closer to the present day. Accurate projection of the first Arctic ice-free summer year is extremely important for business planning and climate change mitigat...

This paper, begins with an overview of the two levels of Bayesian inference: model fitting and model selection, and shows how they can be used for the image texture analysis. The applied models are the Gauss-Markov and Gibbs auto-binomial Random Fields. In the second part the article introduces a linear model for the image wavelet coefficients able to explain the full description of the spatial...
