Why do sudden and massive social, economic, and political changes occur when and where they do? Are there institutional preconditions that encourage such changes when present and discourage such changes when absent? In this paper, I employ a general model which suggests that such changes are more

•  A signal is composed of low and high frequency components low frequency components: smooth / piecewise smooth high frequency components: oscillatory Neighboring pixels have similar brightness values Neighboring pixels have different brightness values You’re within a region You’re either at the edges or noise points

, the detection of anomalies is needed. In this paper we introduce a method for detecting sudden changes applying windowed moving variance computation technique.

of the propagation of changes in traffic distribution along these roads may be deduced (??2, 3). The theory is applied (?4) to the problem of estimating how a 'hump', or region of increased concentration, will move along a crowded main road. It is suggested that it will move slightly slower than the mean

in homogeneous regions of foreground objects; and the frame-level component detects sudden, global changes in the image and swaps in better approximations of the background. We compare our system with 8 other background subtraction algorithms. Wallflower is shown to outperform previous algorithms by handling a

This paper investigates sudden changes in volatility in the stock markets of new European Union (EU) members by utilizing the iterated cumulative sums of squares (ICSS) algorithm. Using weekly data over the sample period 1994-2006, the time period of sudden change in variance of returns
