  • Fracture aperture and fill characterization in a limestone ...

    In previous appliions to fracture characterization, AVO analysis has not been applied to thin fracture such as typically encountered in the subsurface. This paper reports on thin fracture aperture and fill permittivity characterization in a limestone quarry using AVA analysis. The analysis considers the case where the host rock is not homogeneous rock above and below the fracture have ...

  • Thermogravimetric Analysis of Carbonate Aggregate

    10 years, the Iowa DOT has begun using Xray analysis to predict the durability of coarse aggregate for pee pavement (1). This research has been highly successful in developing an Xray diffraction method of identifying nondurable Iowa do­ lomitic aggregates. The durability correlates very well with the dspacing of the maximum intensity dolomite peak. A dspacing of less than would ...

  • Geotechnical Characterization of Jordanian Limestone

    However, Zarka limestone is an impure limestone and can be characterized as marly limestone and has a yellow color. The NX size cylindrical cores were prepared with the help of diamond core drilling machine as per ISRM standard [9] . The coring process was applied perpendicular to the bedding planes of the rock. Samples with cracks or defects were excluded from further analysis.

  • Detection and Characterization of Port Scan Attacks

    The analysis was conducted on the UCSD ActiveWeb machines. We used Snort to simplify scan detection and logging. Snort is a freeware traffic analyzer much like tcpdump, with the addition of preprocessors that allow for packet sorting based on a set of predefined rules. We then used a series of Perl scripts to further analyze the results and
