چکیده
Web access logs, usually stored in relational databases, are commonly used for various data mining and data analysis tasks. The tasks typically consist in searching the web access logs for event sequences that support a given sequential pattern. For large data volumes, this type of searching is extremely time consuming and is not well optimized by traditional indexing techniques. In this paper we present a new index structure to optimize pattern search queries on web access logs. We focus on its physical structure, maintenance and performance issues.

Introduction: Web logs are the evident tools for the librarians. There are three main ways for applying web logs in librarianship fields, as follows: personal use by librarian to upgrade their personal information, as a source of information in case of libraries, and for their services. The aim of this research is to comparison between Iranian libraries and librarians, and superior librarianshi...
متن کاملDevelopment of an Intelligent System to Synthesize Petrophysical Well Logs
Porosity is one of the fundamental petrophysical properties that should be evaluated for hydrocarbon bearing reservoirs. It is a vital factor in precise understanding of reservoir quality in a hydrocarbon field. Log data are exceedingly crucial information in petroleum industries, for many of hydrocarbon parameters are obtained by virtue of petrophysical data. There are three main petrophysical...
متن کاملSystematic fractures analysis using image logs and complementary methods in the Marun Oilfield, SW Iran
Fractures are considered as one of the important structures in fractured reservoirs due to their effect on fluid currents and reservoirparameters such as porosity and permeability. Fracture parameters can only be directly calculated with core and image logs. Cores haveserious limitations, so image logs are the best method. The aim of this study is the systematic fractures analysis of the Asmari...
متن کاملA programming method to estimate proximate parameters of coal beds from well-logging data using a sequential solving of linear equation systems
This paper presents an innovative solution for estimating the proximate parameters of coal beds from the well-logs. To implement the solution, the C# programming language was used. The data from four exploratory boreholes was used in a case study to express the method and determine its accuracy. Then two boreholes were selected as the reference, namely the boreholes with available well-logging ...
متن کاملImproving Petrophysical Interpretation of Conventional Log by Determination of Real Bed Boundaries
Proper determination of bed boundaries in layered reservoirs is vital for accurate petrophysical interpretation of conventional logs. In the wellbore, logs continuously measure physical properties of reservoir while the properties change stepwise. This continuous representation of logs may lead to ignorance of some high potential reservoir zones. The main reasons for continuous nature of l...

Well logs are principal sources of subsurface geological information. They provide significant information on mineralogical composition, texture, sedimentary structures and petrophysical properties such as porosity and permeability. By compiling data from various well logs, one can discriminate sedimentary units with comparable log characteristics. Sedimentary units with similar fluid flow and ...
