Recent experimental investigations and physical modeling studies have indicated that turbulence behaviors within a liquid jet have considerable effects on the atomization process. For certain flow regimes, it has been observed that the liquid jet surface is highly turbulent. This turbulence characteristic plays a key role on the breakup of the liquid jet near to the injector exit. Other experim...

Loop detectors are the most common sensors used to collect freeway management data. There has been considerable research to screen the quality of loop detector data, but some significant detector errors have not received much attention due to the difficulty of identifying their occurrence. This paper examines one such error, pulse breakup: what should be a single pulse from a vehicle breaks up ...

The breakup of droplets occurs in the combustion of multiphase mixtures and the atomization of liquid jets. Most experiments studying droplet breakup have used the passage of a normal shock to provide a step change to uniform flow conditions. In the late 1950s, Engel [2] investigated how water droplets of various sizes broke up in the flow behind air shocks of different strengths. The subsequen...

The cross sections for the (8 B, 7 Be-p) breakup reaction on 58 Ni and 208 Pb targets at the beam energies of 25.8 MeV and 415 MeV have been calculated within a one-step prior-form distorted-wave Born approximation. The relative contributions of Coulomb and nuclear breakup of E1 and E2 multipolarities as well as their interference have been determined. The nuclear breakup contributions are foun...

This study investigated the prevalence and predictors of unwanted pursuit behaviors among college students. Participants (n = 282) had experienced the termination of a meaningful romantic relationship. Two questionnaires were administered. One assessed unwanted pursuit behaviors that were perpetrated by individuals who had not initiated the relationship breakup (breakup sufferers; n = 120); the...

The scattering of proton-halo nucleus 8B from 208Pb at 170.3 MeV is shown to reveal a distinctive pattern in the change in |SL| that is induced by coupling to breakup channels. The same pattern had been found for 8B scattering from 58Ni at 30 MeV, an energy near the Coulomb barrier, and has been linked to various other respects in which scattering for this proton-halo nucleus differs from that ...

This paper describes a novel method for quantitatively and routinely identifying auroral breakup following substorm onset using the Time History of Events and Macroscale Interactions during Substorms all-sky imagers. Substorm onset is characterized by a brightening of the aurora that is followed by auroral poleward expansion and auroral breakup. This breakup can be identified by a sharp increas...

The breakup of the shearless invariant torus with winding number ω = √ 2 − 1 is studied numerically using Greene’s residue criterion in the standard nontwist map. The residue behavior and parameter scaling at the breakup suggests the existence of a new fixed point of the renormalization group operator (RGO) for area-preserving maps. The unstable eigenvalues of the RGO at this fixed point and th...
