On recursive stopping of decimation of discrete-time bandlimited signals

open access: yesLietuvos Matematikos Rinkinys, 2011
For each non-decimated as well as decimated realization discrete-time Fourier series coefficient values, located at Nyquist frequency are calculated, using original speedy recursive expressions based on reverse order processing of the given realizations.

Stop the top background of the stop search [PDF]

open access: yesJournal of High Energy Physics, 2012
Abstract The main background for the supersymmetric stop direct production search comes from Standard Model $ t\overline t $ events. For the single-lepton search channel, we introduce a few kinematic variables to further suppress this background by focusing on its dileptonic and semileptonic topologies ...

Online Computation of Time-Optimization-Based, Smooth and Path-Consistent Stop Trajectories for Robots

open access: yesRobotics, 2022
Enforcing the cessation of motion is a common action in robotic systems to avoid the damage that the robot can exert on itself, its environment or, in shared environments, people. This procedure raises two main concerns, which are addressed in this paper.

Social-class differences in spacing and stopping during the historical fertility transition: Insights from cure models [PDF]

open access: yesDemographic Research
BACKGROUND: There is a long-standing debate about the role of spacing and stopping in the fertility transition, fueled by a lack of methods to appropriately model spacing and stopping. Traditional event-history analysis cannot distinguish between the two
