Orbit determination of space objects based on sparse optical data
orbit determination space debris
2011/3/4
While building up a catalog of Earth orbiting objects, if the available optical observations
are sparse, not deliberate follow ups of specific objects, no orbit determination is possible
without pre...
Spatially regularized compressed sensing of diffusion MRI data
Spatially regularized compressed diffusion MRI data
2010/12/3
Despite the relative recency of its inception, the theory of compres-sive sampling (aka compressed sensing) (CS) has already revolutionized multiple areas of applied sciences, a particularly important...
Asymptotic normality of Hill Estimator for truncated data
heavy tails truncation second order regular variation
2010/12/9
The problem of estimating the tail index from truncated data is addressed in Chakrabarty and Samorodnitsky (2009). In that paper, a sample based (and hence random) choice of k is uggested,and it is sh...
Sufficient Conditions for Fredholmness of Singular Integral Operators with Shifts and Slowly Oscillating Data
Orientation-preserving non-Carleman shift Cauchy singular integral operator
2010/12/14
Suppose is an orientation preserving diffeomorphism (shift)of R+ = (0,∞) onto itself with the only fixed points 0 and ∞. We establish sufficient conditions for the Fredholmness of the singular integ...
