We present the first constant-factor approximation algorithm for the metric k-median problem. The k-median problem is one of the most well-studied clustering problems, i.e., those problems in which the aim is to partition a given set of points into clusters so that the points within a cluster are relatively close with respect to some measure. For the metric k-median problem, we are given n poin...

Telah dilakukan penelitian untuk menentukan bidang gelincir pada daerah Wisata Bukit Chinangkiek, Kabupaten Solok menggunakan metode geolistrik resistivitas dua dimensi konfigurasi Wenner-Schlumberger. Penelitian ini 2 lintasan dengan panjang bentangan 80 meter software Res2Dinv. Hasil pengolahan data berupa penampang bawah permukaan yang menunjukkan bahwa diduga memiliki lapisan batuan gamping...

the need for clean groundwater resources to have sustainable development in a country is undoubted. due to the importance and high quality of karstic waters in supplying water in iran especially in shahrood city, it is attempted in this research work to recognize and explore karstic waters in southwest of tepal area, shahrood. for this purpose, integration of the results obtained from the metho...

Abstract The quality of groundwater standards in Muttom–Mandaikkadu coastal stretch is the focus present study, whose aquifers are particularly at risk due to intrusion marine water. Thirty samples were scrutinized for assessment physical and chemical parameters during January June. Hydrochemical characteristics spatially depicted understand spatial variations such as (pH, EC, TDS, Na + , K Ca ...

Panax Geothermal Limited is developing a geothermal resource in South Australia, the Limestone Coast Project, which is a conventional “hot aquifer” reservoir in a deep sedimentary basin. The initial development is the Pretty Hill Formation sandstones in the Penola Trough of the Otway Basin. The area is an exploited gas basin with modern 3D seismic and excellent existing petroleum well data cove...

Abstract This paper proposes a novel method to measure each constituent of an oil–gas–water mixture in water continuous flow, typically encountered many processes. It deploys dual-plane electrical resistance tomography sensor for measuring dispersed phase volume fraction and velocity; gradiomanometer flow density meter drift flux model estimate slip velocities; with absolute pressure temperatur...
