S ri Lanka having an a g r i c u l t u r e b a s e d civilisation with an agricultural history of over 13,000 years, the archaeological evidence to confirm the ex is tence of a nomadic era is very scanty or nil. There are still doubts about the indigenous cattle in Sri Lanka, as to whether they are truly indigenous or have been introduced during sometime in the history from our neighbouring cou...

Differential SAR Interferometry (D-InSAR) is an effective tool in monitoring land subsidence because of its greater coverage area and better resolution of height change. A series of Japanese Earth Resources Satallite-1 (JERS-1) images from 1992 to 1998 has been used in monitoring the mine subsidence in the test site of this study, one of the important coal mining areas in China. D-InSAR procedu...

The Itai-Itai disease case is one of four major pollution-related lawsuits occurring in Japan after World War H. This paper, which is based on investigations of the pollution source, the Kamioka mine, considers (1) the history of the disturbances to the environment caused by the Kamioka mine; (2) the Itai-Itai disease suit; (3) the pollution nprevention measures and methods of the Kamioka mine ...

water has an important role in creating pollution problems in the mining regimes influencing the surrounding surface environment. the purpose of this study is to make an assessment of groundwater quality in an underground mine site in portugal with a view of determining the pollution potential of groundwater. in the corresponding surface area of this underground mine, intersections of fou...

Geographic Information System (GIS) is a computer-based system used to store and manipulate geographic information. In this study, GIS is used to obtain information about "open green space of urban areas" (RTHKP). Office of street lighting and Cemetery Palembang is one agency that regulates the green open spaces but not using media such as websites that support the community to get information ...

We consider the problem of testing distribution identity. Given a sequence of independent samples from an unknown distribution on a domain of size n, the goal is to check if the unknown distribution approximately equals a known distribution on the same domain. While Batu, Fortnow, Fischer, Kumar, Rubinfeld, and White (FOCS 2001) proved that the sample complexity of the problem is Õ( √ n ·poly(1...

The Asymptotic Equipartition Property (see, e.g., [3]) implies that, if we choose the characters of a string s of length n independently and according to the same probability distribution P over the alphabet then, for large values of n, the 0th-order empirical entropy H0(s) of s (see, e.g., [4]) will almost certainly be close to the entropy H(P ) of P . Batu, Dasgupta, Kumar and Rubinfeld [1] s...

nitrogen oxides and carbon monoxide gases together with dust are known as the major pollutants arising during the blasting operations using the ammonium nitrate-fuel oil (anfo) explosive at the sungun surface mine, located in the northwest of iran. the pollutants were monitored during some blasting operations at the mine. it was concluded that the gases and dust clouds initially went up to the ...
