چکیده
This research-in-progress paper attempts to identify events that have an effect on future oil price changes based on the predictive power of news messages on the oil market. For this purpose, text mining algorithms are used to determine whether news messages can be regarded as oil-relevant. Examining some 45 million news messages over a period of 8 years, a decision support system is constructed for early warning purposes. The system uses an indicator metric that triggers an alarm for events that will have an impact on the future (short-term) oil price. Relating to historic oil price series, regression analyses formally attest the predictive power of online news messages and thus the potential of the early warning system.

wnloade eted therapy for cancer, which is specifically directed toward the cancer without any potential for outside of controlling the tumor, is a gold standard for treatment. Ewing's sarcoma contains the tial target EWS-FLI1, as a result of a pathognomonic chromosomal translocation. The EWS-FLI1 protein includes the EWS domain, a potent transcriptional activator alongside the highly conserved ...

The purpose of this study was to determine computer and Internet use in agricultural extension by Extension Workers (EWs). This study used a descriptive-correlational design.Population for the study consisted of all extension workers (N= 320) in Isfahan Province, Iran. A stratified sampling technique and census was used to select EWs (n = 200). Overall, findings indicate that EWs have access to...
متن کاملApplication of multifractal modeling for separation of sulfidic mineralized zones based on induced polarization and resistivity data in the Ghare-Tappeh Cu deposit, NW Iran
The aim of this study was to identify various sulfidic mineralized zones in the Ghare-Tappeh Cu deposit (NW Iran) based on geo-electrical data including induced polarization (IP) and resistivity (RS) using the concentration-volume (C-V) and number-size (N-S) fractal models. The fractal models were used to separate high and moderate sulfidic zones from low sulfidic zones and barren wall rocks. B...
