A general equation of state for fluids of any number of phases is derived. The equation contains the principal experimental state equations as special cases. The non-additive energies of 3, 4, ... particles must also be considered, plus the additive…

We present a secure deterministic cipher and decipher mechanism based on the well-known Lorenz dynamic system. The ciphering process is performed by the combination of the message to be ciphered and the states of the Lorenz dynamic system, which act…

The Mw7.8 Kunlun earthquake of 14 November, 2001, in the northern Tibetan Plateau of China, was the largest event in the Chinese continental area in the latest 50 years. In this paper, layered visco-elastic models are calculated using the PSGRN/…

Apparent dips from 3-D reflectors are calculated by maximizing the semblance-based coherency (C2) by numerical optimization techniques. This maximization was done by means of searching through a tessellation of the apparent dips domain, and by optimization algorithms. We applied the…

A severe salt water intrusion in Guaymas Valley, Sonora is mapped by means of 44 time-domain electromagnetic soundings. In the southern part of the valley the resistivity distribution is simple. A conducting layer associated with the saline intrusion in the…

Currents data from a ten-month period at 197 measuring points covering all Yucatan Channel were processed by harmonic analysis to estimate tidal parameters for the O1, K1, M2 and S2 components. The highly detailed coverage confirms the known dominance for…

In this paper a new Kernel, from statistical learning theory is proposed to work with symbols chains (words) obtained from a discretization procedure of a continuous features. Although the exact definition of the discretization is not strictly necessary, there must…

In this note we present a novel stability analysis method for DC to DC series resonant converters which relies on the phase plane technique. This method gives more insight into the rationale behind the stability conditions because these are obtained…

This study is the first attempt for integration voting algorithms with fault diagnosis devices. Voting algorithms are used to arbitrate between the results of redundant modules in fault-tolerant systems. Smart sensors are used for FDI (Fault Detection and Isolation) purposes…

A Real-Time audio watermarking scheme is proposed, where the strength of audio signal modifications is limited by the requirement of producing an output audio signal that is perceptually equal to the original one. The watermark embedding stage, based on a…
