There is a long history of cryptographic hash functions, i.e. functions mapping variable-length strings to fixed-length strings, with such functions also expected to enjoy certain security properties. Hash functions can be effected via modular arithmetic, recursive permutation-based schemes, chaotic mixing, and so on. Herein we introduce the notion of an Artificial Life (or ALife) hash function...

Cubic equations of state (CEoSs) are extensively used in academia and industry for their consistency, reliability, even under extrapolation conditions, capacity to predict phase-equilibrium energetic properties with acceptable accuracy. The optimal parametrization a pure-component CEoS, prerequisite the development any CEoS mixtures, is discussed first. binary interaction parameter (BIP) involv...

Solubility of hydrocarbons in water is important due to ecological concerns and new restrictions on the existence of organic pollutants in water streams. Also, the creation of a thermodynamic model has required an advanced study of the phase equilibrium between water (as a basis for the widest spread muds and amines) and gas hydrocarbon phases in wide temperature and pressure ranges. Therefore,...

The critical properties of a solute are required for modeling of the solubility by the equation of state. For many compounds, the critical properties are not available. So, group contribution method is utilized as a common method to estimate these properties. But, it leads to the consecutive errors in calculations of the solubility modeling. In this study, Soave-Redlish-Kowang (SRK) and Peng-Ro...

We consider two distinct centers which arise in measuring how quickly a random walk on a tree mixes. Lovász and Winkler [8] point out that stopping rules which “look where they are going” (rather than simply walking a fixed number of steps) can achieve a desired distribution exactly and efficiently. Considering an optimal stopping rule that reflects some aspect of mixing, we can use the expecte...

The magnetic-field dependence of many-body states in quantum dots can be tailored by controlling the mixing of various angular momenta. In lateral quantum dots—defined electrostatically in a two-dimensional electron gas—this mixing can be accomplished by introducing anisotropies in the confinement potential, thereby explicitly breaking rotational symmetry. Mixing can be severe enough to violate...

There have been efforts in the recent years to make home videos look more interesting and pleasing to viewers by mixing it with music. Most of the existing software enables the user to add music of his preference. It assumes that the user has enough knowledge about the aesthetic mixing principles. In our research, we propose a way of adding audio to video by synthesizing appropriate music based...

In this paper we describe an algorithm which generates all colored planar maps with a good minimum sparsity from simple motifs and rules to connect them. An implementation of this algorithm is available and is used by chemists who want to quickly generate all sound molecules they can obtain by mixing some basic components.
