this paper describes a methodology for the integration of well logs and a series of grid-based attributes extracted from interpreted seismic data for prediction of porosity distributions. the studied area is located in the southwest iran. before finding a relationship between the target logs and predicted logs from 3d seismic data, we have interpreted the 3d seismic data in the studied area. al...

Technological development at the end of the 20 Century opened a new gate for globes. In addition to the traditional analogue physical globes their digital counterparts evolved. Both globe representations are based on a threedimensional model of the real world. Because of increasing availability of global data visualization on a global level gains more significance. Therefore many software devel...

Cet article traite de l'exploration d'un réseau par un agent mobile, ou robot, modélisé par un automate fini. Le réseau est anonyme, au sens que les noeuds ne disposent pas nécessairement d'unétiquetage global. Le robot ne dispose pas de connaissances préalables sur la topologie du réseau, ni même sur sa taille. Sa tâche consistè a traverser chacun des liens du réseau. Nous montrons que, pour t...

Abstract The present paper considers a model that indicates the structure of inhomogeneity for marginal distributions ordinal categorical data. is based on complementary log–log transformation cumulative probability. A theorem homogeneity holds if and only proposed mean variance equality given. Also, conditional distribution considered under certain condition.

Novel storage solutions like RAMCloud promise never seen before latency by storing all their data in main memory. To efficiently store and retrieve objects from memory some systems reuse ideas from log-structured file systems and utilise a log like data structure to hold the data objects in DRAM. Instead of updating data in place, with log-structured memory any modification to the data generate...

The dynamic maintenance of the convex hull of a set of points in the plane is one of the most important problems in computational geometry. We present a data structure supporting point insertions in amortized O(log n · log log log n) time, point deletions in amortized O(log n · log log n) time, and various queries about the convex hull in optimal O(log n) worst-case time. The data structure req...

GIS is considered an important technique as well as a prerequisite for cost effective mineral exploration and determination of high potential areas. The purpose of this research is to determine high potential iron zones for detailed exploration using index overlay GIS method. Index Overlay was used to combine the geology, topography (scale: 1:1,000), lineaments, remote sensing (ASTER and ETM+) ...

The Paleogene Liushagang Formation is part of the Fushan Sag, a continental lacustrine basin located at theSoutheastern margin Beibuwan Basin, South China Sea. Further understanding deep-water gravityflow deposits in this formation will be conducive to lithologic reservoir exploration sag. In study,three members Formation, SQEls3 SQEls2 and SQEls1, from old young, are used withcore observation,...
