We develop a density functional theory and investigate the interfacial tension of several pure substances N(2), CO(2), H(2)S, normal alkanes from C(1) to nC(10), and binary mixtures C(1)/C(3), C(1)/nC(5), C(1)/nC(7), C(1)/nC(10), CO(2)/nC(4), N(2)/nC(5), N(2)/nC(6), N(2)/nC(8), N(2)/nC(10), nC(6)/nC(7), nC(6)/nC(8), and nC(6)/nC(10). The theory is combined with the semiempirical Peng-Robinson e...

The limit of an infinite number of quark colours turns out to be a very useful starting point to understand many features of the strong interaction. The SU(NC) gauge theory simplifies considerably at NC →∞, while keeping the most essential properties of QCD. Choosing the coupling constant gs to be of O ( 1/ √ NC ) , i.e., taking the large–NC limit with αsNC fixed, there exists a systematic expa...

Based on the results of Blum, Shub and Smale 1], Meer 5], Cucker and Matamala 3] and Koiran 7], we develop the study of real computation models restricted to additive operations. More speciically we introduce some complexity classes deened by algebraic circuits and we study their relationships with the real computation model. We show that the languages accepted by nonuniform additive circuits o...

We examine a dual theory of a Supersymmetric Standard Model(SSM) in terms of an SU(3)C gauge group. In this scenario, it is naturally understood that at least one quark (the top quark) should be heavy, i.e., almost the same order as the weak scale. Moreover, the supersymmetric Higgs mass parameter μ can naturally be expected to be small. This model automatically induces nine pairs of composite ...

The presence of pronounced inequalities in mortality and life expectancy across income, education and social groups has long been a “stylized fact” of demography. Research across a large number of developed and wealthy countries, including Ireland, has shown that those with fewer resources, less education or a lower occupational class have higher standardised mortality rates (SMRs) than more ad...

In order to study circuit complexity classes within NC in a uniform setting we need a uniformity condition which is more restrictive than those in common use Two such conditions stricter than NC uniformity Ru Co have appeared in recent research Immerman s families of circuits de ned by rst order formulas Im a Im b and a unifor mity corresponding to Buss deterministic log time reductions Bu We s...

We show that ACC0 is precisely what can be computed with constant-width circuits of polynomial size and polylogarithmic genus. This extends a characterization given by Hansen, showing that planar constant-width circuits also characterize ACC0. Thus polylogarithmic genus provides no additional computational power in this model. We consider other generalizations of planarity, including crossing n...

STEP (STandard for the Exchange of Product model data, ISO 10303) data for numerical control, or STEP-NC, is intended to provide full product and process data interoperability between computer-aided manufacturing systems and machine tool controllers. Numerous prototype and several commercial implementations of STEP-NC are currently being developed. Testing is an essential step toward ensuring c...
