Many mobile applications have evolved from simple HTML pages to complex service-oriented applications that have high maintenance cost. This high maintenance cost is due to the heterogeneity of mobile applications, to the fast mobile evolution and to the fast-moving market which imposes short development cycles and frequent modifications. In order to control the maintenance cost, quantitative me...

Exact and/or rigorous results are reviewed for the Ising and XY /Villain spin glasses in finite dimensions, such as the exact energy, correlation identities and a functional relation between the distribution functions of ferromagnetic and spin glass order parameters. This last relation is useful to prove that the phase space is not complex on a line in the phase diagram. The spin wave theory ne...

The hoarseness diagram supplies a method to quantitatively describe the periodicity and the noise content of voices. It is based on four acoustic measures, three of which assess different aspects of periodicity (jitter, shimmer, mean period correlation) while one indicates the relative amount of additive noise (glottal to noise excitation ratio). The behavior of these measures is discussed in d...

Phase behaviors of binary alloys with an embedded atom model potential are investigated using the thermodynamic perturbation theory. The free energies of the liquid and solid phases are computed using the fundamental measure density functional theory and accurate approximations to the hard-sphere mixture correlation functions. The method is applied to calculate the Au-Cu alloy phase diagram. To...

The capability to enhance or suppress the nucleation of protein crystals opens opportunities in various fundamental and applied areas, including protein crystallography, production of protein crystalline pharmaceuticals, protein separation, and treatment of protein condensation diseases. Herein, we show that the rate of homogeneous nucleation of lysozyme crystals passes through a maximum in the...

We present a metallicity distribution based on photometry and spectra for 442 ω Centauri cluster members that lie at the main sequence turnoff region of the color-magnitude diagram. This distribution is similar to that found for the red giant branch. The distribution shows a sharp rise to a mean of [Fe/H] = –1.7 with a long tail to higher metallicities. Ages have then been determined for the st...

In this work, we investigate the quantum phase transition in a non-Hermitian XY spin chain. The diagram shows that critical points of Ising expand into zone after introducing effect. By analyzing gap and long-range correlation function, one can distinguish different phases by means features decay properties tricky problem traditional model. Furthermore, results reveal relationship among regions...

abstractthe understanding of water resources for the purpose of ground and surface water management as two inseparable systems is great importance. in this study by examining the time series of climatic variables (precipitation), hydrological (flow and consume) and the level of water table, the parameters associated with each other and with fluctuating water table can be realized. there was a d...

an extended peng-robinson equation of state (epr-eos) is used to model the vapor-liquid equilibrium (vle) in systems containing (water + nacl + co2), (water + methanol + nacl + co2), (water + na2so4 + co2) and (water + nh4cl + co2). the binary and ternary interaction parameters between salt and solvent are adjusted to experimental mean solvent activity of salts (nacl and na2so4). for the system...
