Experimental evidence of bouncing localized structures in a nonlinear optical system is reported. Oscillations in the position of the localized states are described by a consistent amplitude equation, which we call the Lifshitz normal form equation, in analogy with phase transitions. Localized structures are shown to arise close to the Lifshtiz point, where nonvariational terms drive the dynami...

The equation of state of nuclear matter suggests that at suitable beam energies the disassembling hot system formed in heavy ion collisions will pass through a liquid-gas coexistence region. Searching for the signatures of the phase transition has been a very important focal point of experimental endeavours in heavy-ion collisions, in the last fifteen years. Simultaneously theoretical models ha...

This paper presents theoretical, computational and experimental aspects of the instability development in the ow of thin uid lms. The theoretical part involves basic uid mechanics and presents derivation of the thin lm equation using lubrication approximation. Simpli ed version of this equation is then analyzed analytically using linear stability analysis, and also numerically. The results are ...

We derived an ordinary differential equation model to capture the disease dynamics during blood-stage malaria. The model was directly derived from an earlier age structured partial differential equation model. The original model was simplified due to experimental constraint. Here we calibrated the simplified model with experimental data using multiple objective genetic algorithm. Through the ca...

Phase transformation tensor Q in the constitutive equation pmposed by Tanaka has been evaluated by employing experimental data of TiNi alloys in a constrained recovery process. It demonstrates that the absolute value of Q for the consmined recovery process is typically about 0.6 0.7 x103 MPa, which is much smaller than that for the stress induced martensitic transformation (typically 2.5 3.5 x1...

a viscosity model, based on eyring’s absolute rate theory combined with a cubic pr equation of state and wong-sandler mixing rule, has been proposed in order to correlate viscosities of aqueous solutions of alkanolamine mixtures at atmospheric pressure and different temperatures. in the proposed method, the energy and size parameters in studied equation of state (eos) have been obtained using t...

We have studied patterns of electrically-driven convective vortices in thin freely-suspended lms of smectic liquid crystal at and above the onset of con-vection. We present measurements of the convective amplitude above onset, the spatial variation of the amplitude due to the presence of end walls, and the relaxation of the amplitude following a sudden change in the experimental control paramet...
