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...

â â â  â â â â â  abstract: â  up to now, the impact of real exchange rate on the non-oil exports of iran has been mainly on focus. however, the more important aspect of the fluctuations in exchange rate is its degree of volatility which can have profound effect on the non-oil exports. hence, the main objective of this paper is to investigate the linkage between non-oil exports and the real exc...

in this work the general aspect and the behavior of a simplified theoretical model for studying mass isolated systems are investigated. the model is in the form of a dual mass model in a single storey arrangement. to find damping ratio and natural frequency of the system, non-classical eigen analysis has been performed on the model. later, time integration analyses subjected to different earthq...

The world today is characterised by the proliferation of information sources available through media such as the WWW, databases, semi-structured files (e.g. XML documents), etc. Nevertheless, this information is usually scattered, heterogeneous and weakly structured, so it is difficult to process it automatically. DENODO Corporation has developed a mediator system for the construction of semi-s...

Along with thc rapid development of Internet and the extensive use of information technology in various fields, large amount of heterogeneous data has been produced. Tbe way of integrating these heterogeneous data has been a hot issue. In this paper, from the problems which enterprise information integration faced, a framework of self-adaptive heterogeneous data integration system (AHDIS) has b...

Cost control and schedule control are two of the most important management functions in the construction industry. Major research efforts are focused on developing procedures for improving the effectiveness of cost and schedule control. As a result, researchers are concerned with the quality, integrity, and timeliness of data that flow through such control systems. A number of data models have ...

Many studies aimed to construct an automated gene expression analysis platform for researchers. However, they lack an integrated data model for analyzing heterogeneous data. In order to address this issue, we created a biological data integration platform for transcriptome analysis (BiDIP) for managing various kinds of databases. As part of this platform, we developed a biological interaction d...
