Pengukuran geolistrik yang dilakukan bertujuan untuk mengetahui keberadaan, kedalaman, ketebalan, jumlah dan penyebaran akuifer. Hasil pengukuran menggunakan konfigurasi Schlumberger di Dusun Mangkung Lauk Desa Mangkung, Kecamatan Praya Kabupaten Lombok Tengah menunjukkan terdapat 5 lapisan penyusun. Lapisan ke-1 berupa lempung dengan tahanan jenis 3.42 – 12.59 Ohm-m. ke-2 breksi nilai 12.50 ke...

Accurate knowledge of soil fertility is required to promote global food security for life sustenance. Literatures have shown that electrical resistivity method effective agricultural site selection without passing through the rigor test. However, factor responsible inconsistence in signature with from one place another, effect texture and depth variation on crop yield are questions this work ge...

Groundwater, one part of water resources is the most needed by humans for life. The availability ground and increasing population growth in Tangkerang Labuai Village reguire use clean water. This study aims to determine rock layers that makes up soil aquifers quality groundwater. For layer, it user Schlumberger configuration geoelectric method,for aquifer test, uses Jacobs step drawdown method ...

Bartal [4, 5] gave a randomized polynomial time algorithm that given any n point metric G, constructs a tree T such that the expected stretch (distortion) of any edge is at most O(logn log logn). His result has found several applications and in particular has resulted in approximation algorithms for many graph optimization problems. However approximation algorithms based on his result are inher...

This report summarizes the CONALD meeting, which took place June 11-13, 1998, at Carnegie Mellon University. CONALD brought together an interdisciplinary group of scientists, concerned with decision making based on data. This report is organized in two parts. The first part (pages 1-6) summarizes the CONALD meeting and highlights its main outcomes, beyond the individual workshop level. The seco...

The fifth Distributed Artificial Intclligencc Workshop tias held at the Schlumberger-Doll Research Laboratory from October 14 to 17, 1984 It was attended by 20 participants from academic and industrial institutions. As in the past,’ this workshop was designed as an informal meeting It included brief research rcport,s from individual groups along with genera1 discussion of questions of common in...

During the past thirty years concrete has developed enormously in both strength and durability. A downside of these improvements is the increased risk of explosive spalling in case of fire. The moisture inside the concrete plays an important role in this spalling mechanism. As the temperature is increasing during a fire the water will start to boil in the concrete. However due to its low permea...
