Time-Frequency Analysis of Superorbital Modulation of X-ray Binary SMC X-1 by Hilbert-Huang Transform
Time-Frequency Analysis Superorbital Modulation X-ray Binary SMC X-1 Hilbert-Huang Transform
2011/10/21
The high-mass X-ray binary (HMXB) SMC X-1 exhibits a superorbital modulation with a dramatically varying period ranging between ~40 d and ~60 d. This research studies the time-frequency properties of ...
Evaluation of alternative formulae for calculation of surface temperature in snowmelt models using frequency analysis of temperature observations
alternative formulae surface temperature snowmelt models frequency analysis temperature observations
2010/4/7
The snow surface temperature is an important quantity in the snow energy balance, since it modulates the exchange of energy between the surface and the atmosphere as well as the conduction of energy i...

LOW FLOW FREQUENCY ANALYSIS OF THE NILÜFER RIVER AT THE GEÇITKÖY STATION, TURKEY
Frequency analysis critical drought flows low flows surface water pollution
2009/10/13
Frequency analysis of low flows (critical drought flows) is the first step in surface water
pollution control. In this study, a Type-3 Extremal (or Weibull) Distribution with a lower limit
is appl...
