Two-phase bubble formation coupled with phase change at a submerged nozzle is studied theoretically. The whole bubble consists of a ®apor and a liquid phase. The inner ®apor phase is assumed to be surrounded by a thin condensate layer, in which the ®apor condenses partially as the two-phase bubble grows. The interface element approach is applied to describe the dynamics of bubble formation. The...

We analyze the phase diagram in effective chiral quark models (the Nambu– Jona-Lasinio model, the σ-model with quarks) and show that at the mean-field level a phase with a periodically-modulated chiral fields separates the usual phases with broken and restored chiral symmetry. A possible signal of such a phase is the production of multipion jets travelling in opposite directions, with individua...

We propose a linear compression technique for the time interval distribution of photon pairs. Using a partially frequency-entangled two-photon (TP) state with appropriate mean time width, the compressed TP time interval width can be kept in the minimum limit set by the phase modulation, and is independent of its initial width. As a result of this effect, ultra-narrow TP time interval distributi...

In the following we will desefibe a PC based system which allows motor disabled persons to control devices in a domestic environment. The system will be able to "learn" and reproduce infrared (IR) code from virtually every IR controller currently available, so it can relay on a wide range of commercial devices, now and in the future. The configuration phase will be quite easy, enabling non-expe...

Resonances appearing in hadronic scattering processes are described by a two-phase model. In the one phase, scattering products are observed, whereas the other phase describes confinement. A so-called “Resonance-Spectrum Expansion” is derived, containing expressions that resemble Breit-Wigner formulae. This method also provides a straightforward explanation for the origin of the light scalar me...

Improving phoneme recognition has attracted the attention of many researchers due to its applications in various fields of speech processing. Recent research achievements show that using deep neural network (DNN) in speech recognition systems significantly improves the performance of these systems. There are two phases in DNN-based phoneme recognition systems including training and testing. Mos...

Forecasting warranty claims for recently launched products that have short histories of claim records is vitally important for manufacturers in preparing their fiscal plans. Since the amount of historical claim data for such products is not large enough, developing forecasting models with good performance has been a difficult problem. The objective of this paper is to develop an algorithm for f...

—Recently there are emerging applications based on opportunistic mobile social networks, which are kinds of delay tolerant networks (DTNs) with social relations between the nodes. In such networking scenarios, messages are disseminated through intermittent connections in a store-carry-and-forward manner. A major advantage of the opportunistic mobile social networks includes enabling communicat...
