Information Extraction from semistructured data becomes more and more important. In order to extract meaningful or interesting contents from semistructured data, we need to extract common structured patterns from semistructured data. Many semistructured data have irregularities such as missing or erroneous data. A tag tree pattern is an edge labeled tree with ordered children which has tree str...

Consider the three-component time series model that decomposes observed data (Y ) into the sum of seasonal (S), trend (T ), and irregular (I) portions. Assuming that S and T are nonstationary and that I is stationary, it is demonstrated that widely-used Wiener-Kolmogorov signal extraction estimates of S and T can be obtained through an iteration scheme applied to optimal estimates derived from ...

The Pliocene lignite hypothesis is an environmental hypothesis that has been proposed to explain the etiology of Balkan endemic nephropathy (BEN). Aqueous leaching experiments were conducted on a variety of coal samples in order to simulate groundwater leaching of organic compounds, and to further test the role of the Pliocene lignite hypothesis in the etiology of BEN. Experiments were performe...

semiarid regions with their exceptional weather conditions, low precipitation, and high evapotranspiration pose a great challenge to water resources managers. one possible way to face this challenge is the conjunctive use of both surface water and groundwater resources in these regions. this paper proposes a conjunctive use model which has been implemented in najafabad plain in central iran. th...

Various researchers have reported and described the adverse effects of saltwater ingression in coastal zones of different parts of world like Italy, Japan, Greek islands, Oman, Nigeria, Atlanta Coast USA, Turkey, Netherlands, Catalonia and Sardinia and various coastal areas of India [1-35]. India has long coastal line of 5700 km. The east coast (Coromandel Coast) extended from West Bengal to Ka...

This study has three objectives, i.e calculating the availability of groundwater in area, water demand for domestic and livestock evaluating safe yield extraction. To achieve these availability, actual utilization are calculated. Groundwater is calculated based on multiplication aquifer thickness specific yield. Water determined base number population amount each person day. consumption day, wh...

• excavating and removing all contaminated soil and disposing of the soil in an environmentally sound manner; • covering the site with a blanket of uncontaminated soil and installing a runoff control and drainage system to limit the potential contamination of surface water or groundwater; • other in-situ treatment methods that involve complex physical and/or chemical neutralization or extractio...

Directional drilling and hydraulic-fracturing technologies are dramatically increasing natural-gas extraction. In aquifers overlying the Marcellus and Utica shale formations of northeastern Pennsylvania and upstate New York, we document systematic evidence for methane contamination of drinking water associated with shale-gas extraction. In active gas-extraction areas (one or more gas wells with...
