Jets with Variable
We introduce a new class of jet algorithms designed to return conical jets with a variable ∆R radius. A specific example, in which ∆R scales as 1/pT , proves particularly useful in capturing the kinematic features of a wide variety of hard scattering processes. We implement this ∆R scaling in a sequential recombination algorithm and test it by reconstructing resonance masses and kinematic endpo...
متن کاملPerformance of CCC-r control chart with variable sampling intervals
The CCC-r chart is developed based on cumulative count of a conforming (CCC) control chart that considers the cumulative number of items inspected until observing r nonconforming ones. Typically, the samples obtained from the process are analyzed through 100% inspection to exploit the CCC-r chart. However, considering the inspection cost and time would limit its implementation. In this paper, w...
متن کاملSome Nucleosynthesis Effects Associated with R-process Jets
Recently I discussed an environment in which a core collapse supernova rotates and has an embedded magnetic field during the collapse. The result should be the formation of a neutron star with a surrounding accretion-extrusion disk and the formation of narrowly collimated jets based in the disk close to the neutron star surface. The disk material in the jets should have a velocity of about 0.5c...
متن کاملLarge-eddy simulation of variable-density round and plane jets
Large-eddy simulations (LES) of heated and cooled plane and round variable-density jets were conducted using a variety of density ratios s 1⁄4 qj=qco , which relates the jet nozzle density qj to the freestream density qco . The initial momentum flux was kept constant for better comparison of the resulting data. Both simulations confirm experimental results, in that the jet half-width grows line...
متن کاملLarge Eddy Simulation of Variable Density Turbulent Axisymmetric Jets
Three cases of variable-density turbulent round jets discharging from a straight circular pipe into a weakly confined low-speed co-flowing air stream are studied with the aid of large eddy simulation. The density ratios considered are 0.14 [He/air], 1.0 [air/air] and 1.5 [CO2/air], with Reynolds numbers of 7000, 21000 and 32000, respectively. Detailed comparisons of the statistics show good agr...
