Testing the lognormality of the galaxy and weak lensing convergence distributions from Dark Energy Survey maps
(Oxford Univ Press, 2017-04-01)
It is well known that the probability distribution function (PDF) of galaxy density contrast is approximately lognormal; whether the PDF of mass fluctuations derived from weak lensing convergence (kappa(WL)) is lognormal ...
Many-body effects in wide parabolic AlGaAs quantum wells
(American Institute of Physics (AIP), 2007-11-01)
Photoluminescence measurements at different temperatures have been performed to investigate the optical response of a two-dimensional electron gas in n-type wide parabolic quantum wells. A series of samples with different ...

Raco Wind at the Exit of the Maipo Canyon in Central Chile: Climatology, Special Observations, and Possible Mechanisms
(American Meteorological Society, 2020)
Raco is the local name given to a strong (gusts up to 17 m s(-1)), warm, and dry down-valley wind observed at the exit of the Maipo River Canyon in central Chile. Its climatology is documented based on eight years of surface ...
State Observer Applied to Position and Vibration Control Using Flexible Link Manipulator
(2021-01-01)
Vibration control techniques are of a great importance in Aerospace Engineering, Automotive Engineering, Mechanical Engineering, and Robotics, providing stability and well damped behavior to control systems. In this context, ...

Deepwater gas kick simulation
(Elsevier Science BvAmsterdamHolanda, 2009)
Analysis of total visual and CCD V-broadband observations of Comet C/1995 O1 (Hale-Bopp): 1995-2001
(ELSEVIER SCI LTD, 2009)
We developed a general method for determination of water production rates from groundbased visual observations and applied it to Comet Hale-Bopp. Our main objective is to extend the method to include total visual magnitude ...
Valence band tail states in disordered superlattices embedded in wide parabolic AlGaAs well
(AMER INST PHYSICSMELVILLE, 2012)
Optical properties of intentionally disordered multiple quantum well (QW) system embedded in a wide AlGaAs parabolic well were investigated by photoluminescence (PL) measurements as functions of the laser excitation power ...
