Despite the unrivalled spatial resolution and depth penetration of active-source seismic methods used for mineral exploration in hardrock environment, economic environmental restrictions (e.g., source permitting) may preclude its full-scale application. In such a case, 2D passive reflection seismics can be considered cost-effective way to perform reconnaissance-type survey provide body-wave str...

This paper proposes a new and e cient two-pass protocol for authenticated key agreement in the asymmetric (public-key) setting. The protocol is based on Di e-Hellman key agreement and can be modi ed to work in an arbitrary nite group and, in particular, elliptic curve groups. Two modi cations of this protocol are also presented: a one-pass authenticated key agreement protocol suitable for envir...

Commercial databases support different isolation levels to allow programmers to trade off consistency for a potential gain in performance. The isolation levels are defined in the current ANSI standard, but the definitions are ambiguous and revised definitions proposed to correct the problem are too constrained since they allow only pessimistic (locking) implementations. This paper presents new ...

Relational database systems (and the related standards body ANSI/INCITS H2) are busy adding XML support. One of the main components of such XML extensions will be support for the upcoming XML query language XQuery. The presentation will outline how XQuery and XML conceptually fit into a relational database environment. It will cover the organization of the XML in the database, how to type it us...

Globalization and technology transfer have led to the diffusion of risk communications to users from cultures that were not initially viewed as the target users. This study examined industry and trade workers' overall impressions of symbols used to convey varying degrees of hazardousness. Six symbols, including symbols from the American National Standards Institute (ANSI) Z535 Standard (ANSI, 1...

This paper is a user’s manual for MCLite, an adaptive multilevel finite element MATLAB package for solving scalar nonlinear elliptic equations in the plane. MCLite is a two-dimensional MATLAB prototype of a more complete twoand three-dimensional ANSI-C code called MC, which expends MCLite’s capabilities to elliptic systems of tensor equations on 2and 3-manifolds. Both codes share the same core ...

A difference of approximately 5 dB exists between the level of spoken English determined using the ANSI standard vu-meter method compared to the common root-mean-square (rms) method. If the rms method is substituted for the present ANSI standard method for calibrating a speech audiometer, for example, the reported speech reception thresholds will improve 5 dB: Speech levels read approximately 5...

In this work, poly (o-Anisidine) (POA) was prepared by consecutive potential cycling in an acidic monomer solution at the surface of Carbon Paste Electrode (CPE). Nickel ions were dispersed into the polymer by immersing the electrode in NiSO4 solution. The prepared Ni/POA/CPE was characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, Atomic Force Mic...
