This paper introduces a multiscale analysis based on optimal piecewise linear approximations of time series. An optimality criterion is formulated and on its base a computationally effective algorithm is constructed for decomposition of a time series into a hierarchy of trends (local linear approximations) at different scales. The top of the hierarchy is the global linear approximation over the...

the central cooperative banks occupy a crucial position in the pyramidal structure of agricultural cooperative banking system. they from the backbone of the agricultural credit structure and provide the vital line between the primary agricultural societies and the state apex cooperative bank functioning at the state level. the study is based on secondary data obtained from annual reports of edc...

Bangladesh is still a low urbanized country although it experienced a rising trend in the level of urbanization throughout the twentieth century and had a remarkably high urban growth immediately after its independence in 1971. The country recorded the highest ever annual average growth rate (9.04) and percentage of interval variation (137.57%) in an urban population in 1974; thereafter, growth...

hydrologic regime is highly dependent on climate change, as hydrologic cycle components are directly influenced by climatic conditions. this paper analyzes the impacts of climate change on the hydrologic regime of the atrak river basin in the northeast of iran. it drains to the caspian sea. the data collected at 11 hydrometeorological stations were examined to detect trends in hydroclimatologic...

The evidence to date suggests that the use of mind-body medicine in chronic pain management can improve physical and psychological symptoms. However, past research evidence has largely relied on global measures of distress at pre- and post-intervention. Even though it is plausible that reported anxiety occurs in the context of pain, there is also evidence to suggest a reciprocal relationship. T...

The Hawkesbury-Nepean River (HNR) system in South-Eastern Australia is the main source of water supply for the Sydney Metropolitan area and is one of the more complex river systems due to the influence of urbanisation and other activities in the peri-urban landscape through which it flows. The long-term monitoring of river water quality is likely to suffer from data gaps due to funding cuts, ch...

Software vulnerabilities exist and will continue to do so. Every week, a new vulnerability gains popular attention, is discussed at length in mailing lists, and hopefully gets patched by the vendor before exploits and attack tools start appearing. But there is little evidence that we are learning from our mistakes. Sharing of vulnerability information through public databases has been possible ...
