Acquisition of pseudonoise signals by sequential estimation
Rapid Acquisition by Sequential Estimation /RASE/ system is used in the receivers of tracking and communications systems to bring identical locally generated pseudonoise digital modulation signal into time synchronization with the incoming pseudonoise signal. This acquisition system is particularly suited for medium input signal-to-noise ratios
Electromagnetic simulation of microwave backscatter from the ocean surface - A feasibility study
Photochemical etching is most successful method for obtaining simulated microwave backscatter pattern from ocean surface. Process is adaptable to integrated circuit and thin film semiconductor fabrications. The attained horizontal resolution of 10 should improve with equipment refinement
IR-Improved DGLAP-CS QCD Parton Showers in Pythia8
We introduce the recently developed IR-improved DGLAP-CS theory into the
showers in Pythia8, as this Monte Carlo event generator is in wide use at LHC.
We show that, just as it was true in the IR-improved shower Monte Carlo
Herwiri, which realizes the IR-improved DGLAP-CS theory in the Herwig6.5
environment, the soft limit in processes such as single heavy gauge boson
production is now more physical in the IR-improved DGLAP-CS theory version of
Pythia8. This opens the way to one's getting a comparison between the actual
detector simulations for some of the LHC experiments between IR-improved and
unimproved showers as Pythia8 is used in detector simulations at LHC whereas
Herwig6.5, the environment of the only other IR-improved DGLAP-CS QCD MC in the
literature, Herwiri1.031, is not any longer so used. Our achieving the
availability of the IR-improved DGLAP-CS Pythia8 then is an important step in
the further development of the LHC precision theory program under development
by the author and his collaborators.Comment: 6 pages, 1 figur
