Adaptive Set Observers Design for Nonlinear Continuous-Time Systems: Application to Fault Detection and Diagnosis
Adaptive observers nonlinear continuous-time systems fault detection interval residuals
font style='font-size:12px;'>
2010/12/28
The paper deals with joint state and parameter estimation for nonlinear continuous-time systems. Based on a guaranteed LPV approximation, the set adaptive observers design problem is solved avoiding t...
Local-Testability and Self-Correctability of q-ary Sparse Linear Codes
Local-Testability Self-Correctability q-ary Sparse Linear Codes
font style='font-size:12px;'>
2011/3/3
We prove that q-ary sparse codes with small bias are self-correctable and locally testable. We generalize a result of Kaufman and Sudan [3] that proves the local testability and correctability of bina...

We study codes with a single check element derived from group rings, namely, checkable codes. The notion of a codecheckable group ring is introduced.
Improved linear programming decoding of LDPC codes and bounds on the minimum and fractional distance
Improved linear programming LDPC codes bounds minimum fractional distance
font style='font-size:12px;'>
2011/1/19
We examine LDPC codes decoded using linear programming (LP). Four contributions to the LP framework are presented. First, a new method of tightening the LP relaxation,and thus improving the LP decoder...
