Mathews, V. John | A stable adaptive Hammerstein filter employing partial orthogonalization of the input signals | Abstract-This paper presents an algorithm that adapts the parameters of a Hammerstein system model. Hammerstein systems are nonlinear systems that contain a static nonlinearity cascaded with a linear system. In this paper, the static nonlinearity is modeled using a polynomial system, and the linear ... | | 2006 |

Stevens, Kenneth | Algorithms for MIS vector generation and pruning | Ignoring the effect of simultaneous switching for logic gates causes silicon failures for high performance microprocessor designs. The main reason to omit this effect is the run time penalty and potential over-conservatism. Run times are directly proportional to the vector sizes. Efficient algorithm... | | 2006 |

Gesteland, Raymond F.; Atkins, John F. | Evolutionary specialization of recoding: frameshifting in the expression of S. cerevisiae antizyme mRNA is via an atypical antizyme shift site but is still +1 | An autoregulatory translational shift to the +1 frame is required for the expression of ornithine decarboxylase antizyme from fungi to mammals. In most eukaryotes, including all vertebrates and a majority of the studied fungi/yeast, the site on antizyme mRNA where the shift occurs is UCC-UGA.

Balasubramonian, Rajeev | Exploiting eager register release in a redundantly multi-threaded processor | Due to shrinking transistor sizes and lower supply voltages, transient faults (soft errors) in computer systems are projected to increase by orders of magnitude. Fault detection and recovery can be achieved through redundancy. Redundant multithreading (RMT) is one attractive approach to detect and r... | Transient faults; Soft errors; Redundant multithreading; Eager register release; Register file design | 2006 |
