Population balances represent an effective framework for the analysis of rate processes in dispersed phase systems. Mainly, they are able to account for the dynamics of the dispersed phase because of particle breakup and agglomeration while concurrently accounting for the rate processes in single particles. The effectiveness of this framework depends on whether particle phenomena (such as break...

This paper discusses procedures for approximating high-order rational Dower spectrum matrices and minimum ~ h a s e stable transfer function matrices by lower-order objects of the same type. The basis of the approximation is to secure closeness of a high-order and low-order minimum phase stable transfer function matrix in phase, and to infer from this, closeness in magnitude. A suitable definit...

The successive phase transitions of [Mg(H?0)6][SiF6] were studied by measuring 2 H NMR spectra. The quadrupole coupling constant eQq/h and asymmetry parameter 77 changed drastically at each transition temperature. 1 2 H and 1 F NMR T\ were measured for this compound to study the relation between the molecular motions and the successive phase transitions. The activation energy Ea and the pre-exp...

In-flight vibration measurements from the transmission of an OH-58C KIOWA are analyzed. In order to understand the effect of normal flight variation on signal shape, the first gear mesh components of the planetary gear system and bevel gear are studied in detail. Systematic patterns occur in the amplitude and phase of these signal components with implications for making time synchronous average...

Phase vocoder approaches to time-scale modification of audio introduce a reverberant/phasy artifact into the time-scaled output due to a loss in phase coherence between short-time Fourier transform (STFT) bins. Recent improvements to the phase vocoder have reduced the presence of this artifact, however, it remains a problem. A method of time-scaling is presented that results in a further reduct...

The aim of this study is to investigate of the synchronization of periodic rhythmic movements with single discrete movements as reaction to external trigger signals. The underlying coordination principle derived from the experimental results is supposed to be either phase entrainment or phase reset. In phase entrainment, the response is more probable to occur during the phase, when the periodic...

somatic embryogenesis is a new approache to plant mass in vitro propagation. this method influences by elements and their components in medium. in order to investigate the effects of different media and it,s role on somatic embryogenesis of carrot, a cbd experiment with four replications (including 12 treatments) was conducted. to do this, carrot petioles (with 1 cm dimension) in induction phas...

based on the {s+, i-} pathway, the concentration of surfactant and surface charge density of silanolate groups control the phase transition from lamellar, to hexagonal through cubic form. the high surface charge density of silanolate groups was observed for the lamellar phase. with decrease of molar concentration of surfactant on the gel, the yield of reaction decreases and the stability of mes...
