An Efficient Coupled Genetic Algorithm-NLP Method for Heat Exchanger Network Synthesis

Synthesis of heat exchanger networks (HENs) is inherently a mixed integer and nonlinear programming (MINLP) problem. Solving such problems leads to difficulties <span style="font-size: 10pt; color: #00...

Simple Extractors via Constructions of Cryptographic Pseudo-random Generators

Trevisan has shown that constructions of pseudo-random generators from hard functions (the Nisan-Wigderson approach) also produce extractors. We show that constructions of pseudo-random generators from one-way permutations (the Blum-Micali-Yao approach) can be used for building extractors as well. Using this new technique we build extractors that do not use designs and polynomial-based error-co...

APG: An Efficient Software Program for Amp-Pl Thermobarometry Based on Graphical Method

Geothermobarometry equations are based on thermodynamic principles and appear in single or multi-variant functions. The number of variants for a specific composition or reaction usually is reduced into 2 involving temperature (T) and pressure (P). Since most of planned equations have two passive or variant P and T, using these equations should be with special care. It is very effective to use g...
